Dow/Kokam Powered Zombie…10s in 2010! (pt. 4)

December 26th, 2009

Hello to All,

Just in time for the Christmas holiday weekend, here’s the final installment, pt.4:

Continued from pt. 3…

On the surface, it seems the car will lose 450 lbs. or so, but other structural mods to the car adds back some weight. You’ll have to tune in to pt. 4 to get that and other interesting info on how things are progressing.

To understand where the status of the Zombie’s redesign is currently at, I need to back up a bit and redefine the timeline. When a big break through like a major battery sponsorship occurs, it’s as if a huge puzzle gets dumped on a table with all the pieces scattered about - pieces that you have to assess, then assemble into a completed project - and completing this project proved to be harder than I thought. Like any Waylandesque tale, there’s drama in how it has unfolded.

Following our failure to have an updated Zombie at the July 24th & 25th summer WI-IV races, the Kokam sponsorship deal we had been nurturing suddenly went on a fast track timeline. Just two and a half weeks after the races, we had our first meeting in mid-August here in Portland with Kokam’s national sales manager, Don Sandler. Two weeks later as August turned into September, Rich and I were in Missouri at Kokam America. Two weeks later in mid-September as promised by Kokam (and mentioned in my pt. 2 story) a shipment of 210 ultra high power Kokam cells arrived at the NWHS forklift facility, where I wasted now time grabbing a Crown stand-up reach and loaded the pallet into my service truck and took it home. In just minutes after backing the service truck to its resting spot in my home’s shop driveway, the pallet load of exotic cells were safely tucked away in my EV shop. - it’s sure handy to have my three wheel Hyster electric sit-down forklift at the ready! Before turning in for the night, I had to go back out to my shop ‘just’ to see if it was a dream, or if after years of trying to get lithium, I ‘really’ had all those ultra high power cells in my shop :-)

With a pallet full of lithium in my shop, the pressure was now on (by me) to get the job done. I ‘really’ wanted to get the Kokam pack designed, fabricated, and installed in the car - and then get back on the track to lay down 10s this year. PIR stays open all through October while flirting with the Portland metro area’s changing-seasons weather, then gives up the fight at the end of October to close for the Winter - not to reopen until March. The Kokam guys too, were quite excited and did all they could, to help us achieve that ambitious goal.

When we were back at Kokam America, we got to see some packaging designs of how various sized and shaped cells were assembled into batteries. One had a cast-formed plastic end cap that had slots where the cells’ tabs came through and then could be connected to adjacent cell tabs. I liked this design, as did Rich Rudman. As stated in my pt. 3 story, I wanted to have the Zombie’s modules made of clear Lexan - nonconductive for safety, strong, and transparent so that the cells could be seen and inspected, plus it would make for great show ‘n tell for PR purposes! It seems that some EV builders just don’t get it, that when you have something special, it needs to be visible and exciting to look at. Nothing frustrates me more, than an EV with boring ’stuff’ hiding one of the most unique aspects of an EV - the electric motor, or having exotic batteries only to have them completely out of view. In addition to breaking records and going quicker and faster, White Zombie has always been about being a great show ‘n tell vehicle to help get every day non-EVers excited. I feel quite privileged to have these expensive and rare model Kokam cells, so putting them inside opaque boxes was not an option.

September was already half over and I still needed to figure out how to make the Lexan modules happen. The tricky part would be creating the slotted end cap piece. Kokam’s CAD guys worked on and sent terrific files of what we wanted, so we had the drawings to aid in CNC-ing the parts we’d need. How cool is it, that our sponsor turns over their engineers to help you out? Rudman warned had me that to do it right, it would take thousands of dollars for material, machining costs, and especially the costs to make a cast plastic end cap piece, if that was the way we would go with the design. He also felt it was pretty much impossible to ‘properly’ design and assemble the modules, for him to finish testing on his new 8 channel BMS boards, then get completed modules installed in the car in time to go racing this year. I knew that too, but I was still pushing to get the car ready to make the last two weekends of October racing at PIR…I’m at the same time a driven person ‘and’ the eternal optimist!

I was looking for someone who would have access to a CNC setup, and, who we might just get excited enough about the lithium-Zombie project that we could get the work sponsored, so I made a call to Bob Fagliano (silent G). You’ll recall from my pt. 2 story, that I said, “Bob’s one of those guys who seems to know everybody, and as I’ve learned, he’s a guy who can get things done!” Without missing a beat, he simply said, “I’ll see what I can do.” The next day, Bob called and asked if I was available for a dinner meeting that night, as he had a guy he wanted me to meet that might be able to help us. At a nice dinner restaurant, I was introduced to Colin Murdoch, who worked at ChemWest, a plastics machining and fabrication facility based here in Portland with a branch in Austin, Texas as well. Their main customer base is the wafer fab industry, and they make pretty much anything that might be needed in the way of plastic shapes and forms. I had brought my trusty Mac laptop, and over dinner and great conversation I showed him Zombie drag videos. It was my hope that I would come away from our meeting with a commitment that ChemWest would sponsor the machining needed to build the complicated end cap pieces out of Lexan. Colin was pretty excited about what we were doing, saying he’d get back to us in a few days. When he called, we got more than we had hoped for, with ChemWest offering to not only provide all the labor and machine work, but all the high costing materials as well! It was a huge bonus to have ChemWest providing the material as I was still trying to budget dollars for everything. ChemWest in Portland was quite busy, but Colin had the Austin location ready to do the work for us. I was at the same time, excited about the generous support, and a bit concerned about not having the work done right here in Portland where I could keep an eye on things and have hands-on involvement with the work. We sent the CAD files of the module design to ChemWest, Austin, and hit the ‘go’ button!

ChemWest does plastics only, and will not cut metals with their equipment as metal contamination is a big no-no in the wafer fab industry. I know a bit about this, as in another life I worked for a company that built, sold, and serviced wafer contamination monitors, but that’s another story! Anyway, I still needed to find a machine shop that could CNC copper, as we needed to build all the conductive parts that make up the interconnects and terminals of the module design. Kokam’s engineers had also drawn the design specs for all the copper interconnects and terminals. In the pt. 2 story I wrote, “It took me a while, but I finally realized that sometimes it takes a team approach to get things done, and that’s exactly the change I made in 2009.” Once again, the team approach pulled through, when speaking with Jim Husted, he reminded me about his subleasing setup with Eric at Mountain Machining in Redmond, Oregon. I had met Eric before, and knew he was a nice guy who also happened to be a highly skilled machinist! Eric already has a commuter EV he’s put together, and he’s the guy who does all trick machining for Jim’s hotrod EV motors, so he’s already into EVs. Eric offered to be a Plasma Boy Sponsor and said he could make the hundreds of copper parts for the Zombie’s 13 modules. Did I say 13? Yes, I did! At my request, Kokam had provided enough cells so we could make a spare module, as the car’s design called for an arrangement of 12, 29.6V modules for a 355V system. Track side the 13th module will always be on hand just in case we have a module failure, but it will have a second more ’street oriented’ role. After shaving off the pack’s initial surface charge, the 13th module can be added to the 355.2V pack to up it to 384.8V and a higher capacity 24.6 kWh over the 12 module’s 22.7 kWh capacity…can you say 130 miles range?

Back to the story…as luck would have it, at about the time the Austin facility had been given the green light to acquire material and create the five different Lexan pieces that would make up the module cases (2 thin side panels, 2 thick side panels, a floor panel, the complicated top end cap, and the top cover panel), they suddenly got overloaded with new work, and understandably, paying jobs got the priority - our module project was on hold until early October. This wasn’t good news if we wanted to be on the track by late October! To help us plan the copper pieces needed for the buss bar system however, Adam, the Austin guy, CNC’d the top end cap pieces first, and sent one out to me so we’d have the ability to hand fit metal to check for proper clearance before making an entire run of parts out of expensive copper. Eric came up with a good plan to make a single set of test pieces out of aluminum.

The next chapter in this tale is pretty weird. I had been in both phone and email contact with Adam at ChemWest in Austin. He had sent great photos of the Lexan parts as they were being made, and the workmanship was awesome…things were finally on a roll after a slow start. A little more than a week into October after Adam had worked long days and into the nights working on getting our custom parts finished, everything was finally packaged up and ready for pickup the next morning, as Bob had arranged for overnight next day UPS shipping to Portland. Things get cloudy here, but suffice it to say that the Austin ChemWest guys affirmed the package was sitting in their front office ready for UPS pickup. The UPS driver says he went to pick up the package, but that the ChemWest office was closed…the ChemWest guys said they were there all day and that they even stayed open late so that they would not miss the UPS guy. According to them, the UPS guy never showed. The next day, the package however, was gone and nobody seems to know how it left. UPS claims they never picked it up. In any EVent, all of the custom built one of a kind stuff worth who knows how much, had vanished, and with this misstep so had my dreams of racing with the new pack in 2009! Subsequent tracking of the package showed it was never picked up, and it has never been found. Word on the street however, has it that Dennis Berube’ drove nonstop from Phoenix to Austin, snuck in and grabbed the package, and is now stuffing the enclosures with top secret cells…OK, I made this last part up :-)

It was now mid-October, we had lost all of the Lexan parts, and I had no idea how things would work out. After getting such a late start on making them, the lost module pieces sealed the deal…we were out of it for racing in 2009 :-( Good friend and Team Plasma Boy member Jim Husted put it best in an email he sent to me:

Hey John,

There is no doubt in my mind that the forces of darkness have teamed up against us on all fronts. It’s kind of a bitch that the passion that drives us to do what we do can also work against us in our time of need when the light of the world dims our light. I too, struggle against falling into the pit of darkness during times of trials and tribulations and as much as I realize it, I still fall victim to it. On the other side of the coin, it is very much like the statement that 1 ant won’t kill you but a 1000 will, and I understand how frustrating a 1000 “little” issues can at least just knock the snot out of you. That all said, I am excited about what might be around the bend and hoping a fool’s hope that the anti-EV Gods focus on others so we can get down to making something fun happen. So, in as much as our window may have passed to get Zombie down the track this year, there is much to do to build and ready this pack.

Oh well…in addition to Rudman’s warnings that we would not make my deadline, Tim Brehm (Zombie’s driver and team Plasma Boy lead mechanic) told me that we ‘really’ needed to rework structural parts of the car’s chassis that had been punished by years of wheel-standing launches with a 900 lb. gorilla in the back seat! Inspection of the Zombie’s underside revealed numerous cracks in the warped rear seat area floor boards, cracks in support weldments, cracks at the front floorboards where the roll cage supports met, and deformed leaf spring perches that were literally pushing up through the bottom of the car! With an assembled pack weight of 906 lbs. and with 525 lbs. of that just ahead of the forward spring perches, the violent slams of the slapper bars against the leading end of the leaf springs acted like a BIG hammer banging from underneath at the perches, and once firmly pressed against things, the bars would then lift up the entire car from the spring perch contact point - all this rude force over the years had been tearing welds and bending things! I had to agree with Tim, that the structural problems we’d found needed to be dealt with before powering the car into the 10s.

Side bar…the little Datsun 1200 was built from ‘71 through ‘73 as a light weight (1587 lbs. curb weight) fuem-sniffer econo-car - it was never intended to handle the massive torque of a Siamese 8 hit with 2000 amps -it takes two V8s to do the same! That said, the 1200 sedan has proven itself to be quite sturdy and the 37 year old unibody’s left and right side rails are still straight as an arrow and the rest of the body is in good shape, but as I said, the floorboards and factory subframe rails were definitely tweaked! When I first acquired the car back in 1985, it was already 13 years old and had been through a couple of non-car-guy type owners who had simply put gas in it, driven the crap out of it, and had evidently taken it to the corner gas station repair type shops (not Datsun factory approved dealership shops) whenever work was needed. Evidence…the floorboards had already been mistreated and beat up by what looked like 5 ton floor jacks misplaced under the sheet metal floors (not the structural subframe rails) then slammed up quick where their jack claw had punched through the metal floorboards. Even the two inner front section frame rails had been bent and tweaked by the same rude treatment. I remember lifting the factory rubber floor mats (1200s were so cheap they lacked carpet accept on the tranny tunnel) and seeing the mistreated floorboards, with rust and a few holes in the driver’s side where wet feet had left standing water over the years, and thinking some day I’d redo the floors in the otherwise straight and clean body. Twenty-four years later and with extra destructive help from hard-launches at the drag track, I’m finally forced into getting that done.

With the warm days of summer behind us, PIR about to close for the season, the cold Fall Oregon rains drenching Portland, no module parts, and the bulk of the lithium cells still in their shipping boxes, I gave up my hopes for any more racing in 2009, so White Zombie went 30 miles away to Scapoose, Oregon ending up inside Tim’s shop. It was immediately up on blocks and the tear-down began. All 60 of the Hawker lead acid batteries that comprised the Zombie’s dual string 360V pack were removed, and the car was essentially gutted. Everything removed was weighed on very accurate digital scales, from the battery trays to the power cables to the hold-downs & mounting hardware to the twin pack rear contactors (no longer needed) - everything was weighed.

Tim had hooked up with a couple of car buddies, one who runs ‘Flatline Fabrications’, a place that specializes in creative metal fab for off-roaders, drag racers, etc., and the three man team got out the plasma cutter and went to work. The car’s original mid-body subfloor unibody frame rails extend from the front of the car, then bend down vertical along the lower area of the firewall (where it bends to horizontal to join the front floors) then follow the sheet metal horizontally under the front floors getting smaller and ending about halfway between the firewall and the leading mounts for the front seats. Their spot welds were drilled through to separate them from the floorboard metal, then the original funky floors were cutout and removed. The unibody frame rails were then cut away right at the point where the under-hood portions wrap around the firewall to the underside of the floors, and removed to become scrap metal. Next, two new sheets of steel - one 16 gauge for the floors and the other 11 gauge for beam material, were obtained and readied for some very nice work to follow. I freaked-out a bit, when I learned that the two sheets together weighed 240 lbs.! This is not the way to keep the car light. Tim assured me they bought more steel than would be needed. I insisted that every piece of metal the guys cut away from the car was to be saved and weighed…I’ve always been very good at keeping track of the car’s ever-changing weight through all of its versions, and it’s the reason I’ve been so accurate in predicting the Zombie’s completed curb weight, year after year. I also had the target weight for the new Zombie to not be any heavier than 2300 lbs., and preferably, under that limit.

Unlike classic ‘65-’66 Mustangs or ‘69 Camaros where you can simply order up either factory or replica body panels from fenders to floor board metal, Tim and his friends had to create each piece for the ‘72 Datsun’s floors by hand, with a lot of credit to Flatline Fabrications for their expert work. Copying the basic shape of the four cutout factory pieces (driver’s side front - driver’s side rear, and passenger’s side front - passenger’s side rear) but making one long continuous floor panel for each side and making them completely flat instead of the slight bowl shapes of the original rear floor pieces, the new pieces were drawn up and sheared from the 16 gauge steel sheet, together weighing 37 lbs. The four thinner gauge factory floor pieces, the pair of small subframe rails removed, and the stamped steel seat mount structures together only weighed 23 lbs. - yes, I weighed each part, but the 8 lbs. of undercoat Tim scraped off of the underside of the floors (yes, I weighed that, too) brought the total factory floor weight removed to 31 lbs., so we only gained 6 lbs. with the thicker gauge new floors while losing a bit of sound deadening. The floorboards were nicely welded to the tranny tunnel and the unibody’s side rails (door sill boxed sections), and to the mount pads of the six point roll bar, then everything was seam-sealed, just like factory!

The new ‘under floor’ structural reinforcements are the big change - an improvement the car really needs, and a mod allowed under the Pro Street racing class. 32 lbs. of the 11 gauge material was sheared and folded on the metal brake to create a beefy pair of rigid full length subframe rails. With completely flat floors now, the U-shaped beams were welded to the underside of them and mated to both the under-hood factory beams that bend down and under the front floors and tied into the rear spring perch points, where no subframe beams ever extended to. The spring perch mounts were also boxed-in and fortified. Pictures of are up at the ‘Photos’ section of the web site, under ‘New Floors…out with the old, in with the new!’

With just 345 lbs. of lithium polymer cells taking place of 852 lbs. of lead acid batteries, this is a 507 lb. weight reduction in active material for the car, but the chassis upgrades added 38 lbs. of weight. In addition, there’s a much stronger redesigned drive line loop that’s 5 lbs. heavier, so now the increased weight is at 43 lbs. Then there’s the weight of the Lexan modules, new hold-downs, and new cabling to consider that will add weight again. On the subtraction side of things though, there’s another 54 lbs. that was part of the 906 lb. total weight of the twin 360V lead acid battery pack system, including the rear seat battery box, the trunk floor battery tray, hold-downs and hardware, long inter-pack cabling no longer needed, all the copper bus bars, Lexan pack cover lids, etc. We even shaved 3 lbs. off the aluminum seat mounts made years ago. Back and forth it goes, but in the end it appears the net result will be about a 385 lb. drop in curb weight from 2660 lbs. to an estimated 2275 lbs.

While the car was getting worked over in Scapoose, and prior to the missing Lexan caper, I had been trying to get the best deal on all the expensive copper needed to make the buss bar system for the battery modules. Once again, Bob Fagliano pulled through when he got a killer deal on electrical grade copper flat bar stock. I was grateful that he stopped by my place on the evening of Oct. 22nd and dropped off more than one hundred lbs. of copper (more than we needed), but this was after the bad news of the lost module pieces.

Meanwhile back in Texas…Colin had really gone out on a limb for us, so after all the extra time their guy in Austin spent on our nonpaying job, then the resultant loss of it all, I figured the owners of ChemWest were done wasting their time with us. You can imagine how pleasantly surprised I was then, when Colin called to tell me the ChemWest owner told him to remake all the parts for us!
Of course, now that we had missed our deadline and all urgency had faded away, this time it all went like clockwork, and on Oct. 30th a pallet of 91 Lexan parts (7 pieces per module X 13) was shipped to Portland.

In mid-November, after a lot of hard work with long weekend hours at the Redmond, Oregon Mountain Machining shop, Eric aided by Motor Dog Jim Husted, completed the creation of the hundreds of copper buss bars, copper clamp pieces, and copper output terminals. Bob Fagliano just happened to be in Central Oregon at the time, so as he passed through Redmond on his way back to Portland from the high desert town of Bend, he picked up the copper and hand-delivered them to me. The next week I got together with another of my longtime friends and Team Plasma Boy member, Marko Mongillo, at the sheet metal shop he works at. After hours of effort, I had every single piece of machined copper smoothed and buffed, ready to get nickel plated.

The Lexan parts, as mentioned in pt. 3, turned out to be way thicker than needed (our particular cells do not have to be compressed) and thus were pretty heavy. Lexan is tough stuff, so the half inch thick slab sides of the module body were overkill. Same goes for the other parts of the design as well. The main body - the box part of the module, was a screw-together affair that weighed 5.5 lbs…..yikes! Enter Marko Mongillo again. Re-using the old 1/8 inch Lexan battery compartment lids from the lead acid pack for prototyping purposes, Marko and I came up with a two piece box to replace the five piece screw-together module box. Colin Murdoch helped us figure out how to mate the two pieces, and offered to hot air weld the box pieces at ChemWest. The prototype formed, bent, and welded 1/8 inch Lexan box weighs just a pinch over 1.5 lbs., so that shaves a whopping 4 lbs. off each completed module! We hope to have the lighter weight module cases done in January, then will begin the assembly process of making thirteen, 29.6V, 64 ahr C2, 2,400 amp @ 10 second batteries. Each will be loaded with 16 cells in a 2P8S design, with a Manzanita Micro 8 channel BMS board built in.

As stated, the pack will be capable of 926 hp, but when we hit the track in the Spring, we’ll sneak up on all that power by restricting the controller’s input current. We expect that tapping into only half of the total power available from these killer batteries, White Zombie will run a 10 second ET. After we nail down the 10s, later in the year the full 2.4 kiloamps will be accessed when a second Z2K is connected, a 4 link with a taller ratio goes in back, wheelie bars are added to keep it on the ground, and aero aids are fitted to keep it stable at 130+ mph speeds through the traps. A Siamese 9 may have to replace the smaller Siamese 8 to handle the additional power…we’ll see how this all works out…

It’s going to be a fun 2010!

See Ya…John ‘Plasma Boy’ Wayland

Dow/Kokam Powered Zombie…10s in 2010! (pt. 3)

November 29th, 2009

Hello to All,

Continued from pt. 2…

With the background of this tale now properly set up, and continuing with my tradition of sharing technical info as freely as possible so that others can take advantage of it and help advance EVs by pushing the performance envelope, as promised here are the details of the high power Kokam LiPol pack:

I had hoped that when I got a lithium sponsor, that along with a big weight reduction for the car and the high power output needed to fully feed a hungry Zilla Z2K, that a properly configured lithium pack (read that 300-400 lbs.) might also give the Zombie more than the 30-35 miles of range the lead acid pack gave. I had gotten a sample of the range capabilities of lithium with the borrowed 175 lb. A123. Even though the 880 A123 cells in it weren’t ‘energy density’ types, that tiny pack could still out-range 852 lbs. of lead acid batteries. What could say, twice that weight in lithium do? How cool would it be to have a street legal EV that burns from 0-60 in less than 3 seconds, runs a high 10 second 1/4 mile, ‘and’ had 75 miles range? Do you think that might get the public’s attention? I figured that about 350 lbs. of good lithium power cells would be about right. Anyway, these were the target performance parameters I was hoping a lithium pack could provide for the Zombie, but as I studied the specs of these ultra high power cells and spoke with Kokam’s EE who confirmed that the specs were, if anything - conservative, I began to realize that ‘these’ cells could not only meet my dream specs…they would far exceed them!

The Kokam ultra high power cells really live up to their name, and are seemingly made for EV drag racing. They are considered large format type cells, but at about just 7.5 inches square they’re still smaller than other LiPol type cells. Each is about 1/3 inch thick, and weighs just 1.8 lbs. At 3.7V & 30 ahr, they have a beefy continuous discharge rating of 20C (600 amps) but it’s their <10 second rating of 40C (1200 amps) that puts them in killer territory! Unlike the small cylindrical type cells that have to be paralleled anywhere from 8 - 12 wide in order to achieve the high currents needed for EV drag racing, it takes just two of these Kokam cells in parallel to crank out 2,400 amps for 10 seconds - I’ll repeat that… 2,400 amps for 10 seconds!

Paralleling pairs of cells does more than just making the extraction of extreme currents possible - the pair also effectively creates a 60 hr cell. At the higher C2 discharge rate however, their capacity actually increases to 32 ahr. The cells pass the nail puncture test without exploding (seen it done), without catching on fire (seen it done), and without spewing fountains of chemicals (seen it done)…read that ‘they are safe’. If all this doesn’t already sound terrific, check this out. They have been tested at 100% discharge for 1450 cycles and still had 81% capacity remaining! At 80% DOD they are good for 2500 cycles and still have 91% capacity remaining.

The Zombie started life as Datsun 1200, a little economy car from the early 70’s powered by a tiny 1200cc 4 cylinder gas engine that sipped fuel, and with the body’s small frontal area, its low mass, and its fairly good cd, the Datsun 1200 was rated as America’s highest gas mileage car in ‘73. As a high powered electric car, though it can suck the amps when called on to dispatch a 500 horse Vette, the Zombie’s got a Jekyll and Hyde personality that turns it from a track terror into an efficient EV when driven ‘nicely’.

Before moving on to my predicted specs for the Kokam-powered Zombie, looking back at things (White Zombie History pages makes this easy) will put it into perspective. As we go through this together, forget that White Zombie is primarily a drag racing-focused EV, and rethink of it in terms of usable range per charge. You’ll begin to see why we are so excited about these cells!

Example (1)

The 60, 12V batteries that made up the lead acid pack weighed 852 lbs. and in terms of ‘power density’ could output 1500 amps at an initial sag to 220V at launch, then they would sag lower and lower towards 180V at the end of a run. That’s a max output of 330 kW dropping to 270 kW, or 442 battery hp declining to 362 battery hp. Of all the lead acid batteries I’ve tried over the years, from Optimas to Orbitals and including the various models of Hawkers, the combination of 60 small 16 ahr Hawkers gave the highest ‘power density’ of any lead acid battery, and power density has always been the focus with the batteries used in this car.

In terms of ‘energy density’ with twin strings of 360V @ 16 ahr C20, the combined pack was 360V @ 32 ahr C20, but lead acid being lead acid, at EV currents the actual ahr the combined pack could deliver at the real world C2 was about 16 ahr, resulting in 5.8 kWhr of what I refer to as ‘usable EV capacity’. Even at its heaviest 2660 lb. lead acid state, with the drag radials pumped up hard to 35 psi, the Zombie rolls quite easily and is efficient to the tune of about 190 Whrs per mile @ 55 mph. With the lead acid pack hanging at 375V at 55 mph, the ammeter indicates just 25-30 amps of current being pulled from the pack, so this backs up the 190 Whr per mile claim. An hour of continuous driving at 55 mph would then, give 55 miles range if the batteries could produce about 10.5 kWhrs…but they couldn’t. At 5.8 kWhr, you could get 30 miles of range, and 35 miles at lower urban speeds, hence the 30-35 miles per charge I rated my car at. The battery to vehicle weight ratio (BVR) was 32% so it all fits with the accepted calculations for a lead acid powered EV. Though the Zombie’s primary mission has always been acceleration, it’s also been great to have a decent range per charge (for lead acid) that has allowed the car really be a functional street legal drag car, with the emphasis on the word ’street’. Being able to drive to and from the track (16 miles one way) with opportunity charging at the track, for me, has always added credibility to the car’s mission. As the lead pack aged, that 30-35 miles became more like 25-30 miles. This was again, pretty much proven that Friday night in July of this year, when running on just half of the pack (covered in pt.1) the car did 13 miles of spirited 65 mph freeway driving, then started to fade away, stranding me about 2 miles shy of my place…call it 13 miles of good driving. If both strings had been working, that comes out to 26 miles range @ 65 mph.

Example (2)

Borrowing the crazy little A123 motorcycle pack was an enlightening experience on many levels. Like the Zombie’s lead acid pack, the 175 lb. ‘box ‘O batteries’ was designed with one thing in mind - power density! Bill Dube could care less about energy density when trying to push Killacycle ever quicker and faster through the 1/4 mile…it’s all about power density! 1400 amps from 175 lbs. of cordless drill cells is pretty amazing!

Lithium being lithium, even when the chemistry and the cell’s mechanical design is oriented towards power density, compared to lead acid chemistry you still end up with outstanding ‘energy density’. Point in case…just 175 lbs. of these cells made 6.9 kWhrs of usable EV power (880 cell pack configured at 8P110S - 2.3 ahr X 8 = 18.4 ahr - 3.4V X 110 = 374V - 374V X 18.4 ahr = 6881 Whr or 6.9 kWhr) You can look at it as 5 times the energy density as the lead acid pack, lb. for lb., or perhaps more entertaining, is that a little box 1/5 the size and weight of the lead acid pack, that fit inside the spare tire well area instead of taking up a large portion of the car, made ‘more’ kWhrs, at an impressive 6.9 kWhr vs 5.8 kWhr! To back this up, in an unplanned range test, I put on 32 miles without a recharge driving the Zombie back home from PIR after a night of racing, then drove it back the next night. After 32 miles the pack’s voltage was still ‘right there’…I probably could have made a few hard runs without recharging! Those 32 miles ate up 6 kWhrs of juice, but true to the reputation of lithium having a very flat discharge, with just .9 kWhr left in the pack it seemed quite ready to keep going!

OK, with this out of the way, here’s what I decided would be the best way to utilize the Kokam ultra high power cells to push the Zombie to the next level:

When going from lead acid to lithium, it takes a bit of adjusting one’s thought process on pack voltage. A lead acid pack comprised of 12V ‘nominal’ batteries is pretty easy to figure out, as everyone knows the ‘actual voltage’ of a fully charged 12V battery is about 12.85V or so…call it 13V. If you design a 360V pack, you know it sits at about 390V unloaded. You also know that at full charge when still connected to the charger and in the final constant voltage stage, each battery goes up to around 15V, so the pack rises as high as 450V. You also know that immediately after shutting down the charger, that the 450V rapidly goes away and the pack is below 400V in seconds. By the time you key-on, the pack is in the 390-395V range, safe for the Zilla, and ready to go. Things change with lithium. Knowing that I could pretty much name the number of cells I wanted, I thought of going higher in voltage for the pack. thinking that 208 cells (2P X 104S) would be perfect and would give 384.6V nominal. The problem is, these cells get taken to 4.2V at full charge, then off of charge only drop to 4.1V, for a 426.4V resting voltage after charging…Zilla, not happy :-( I’d have to drop the pack voltage.

As mentioned in pt. 2, I wanted to assemble these cells into modules. I worked closely with Rich Rudman on this with many brainstorming sessions over pie and scribbled-on napkins, and also with him back in Missouri where we ran the concept past the Kokam engineering team. The idea was to keep the design clean, simple, and accessible. It’s the accessible part that dictated a modular design, because having a large assembly of cells all ganged together in the trunk space of the car, makes a package that although small compared to the lead acid pack, is still too heavy and bulky to work on. It also makes it difficult to quickly get to cells if there’s a problem. With a possible TV show in the works (more on this in pt.4) and with Kokam interested in being a supplier of cells for that project, I wanted the modular design so other packs could be configured by adjusting the numbers of and the placement of modules for a given vehicle. Other factors that shaped the module’s design were weight, physical size, shape, current carrying ability, and cell numbers per module. I wanted each module to not be too heavy, so 35-37 lbs. was the goal. Rudman’s newest BMS board is an 8 channel unit, meaning it can keep track of 8 cells (or 8 paralleled groups of cells). At 1.8 lbs. per cell, and needing to have pairs of cells in parallel, a 2P X 8S, 16 cell module made sense. Each module would be made of tough clear Lexan, and the cell’s output tabs would be tied together with high current nickel plated copper buss and clamp bars. With just shy of 29 lbs. of active material (cells) and the heavy 3-4 lbs. of copper interconnects (needed to pass 2.4 kiloamps), hitting that 35-37 lb. goal would be a challenge. At 29.6V, 64 ahr @ C2, and ~36 lbs. per module, and with pack voltage, space constraints, and a pack target weight including cabling and hold-downs of 450-460 lbs., I went with a 12 module, 192 cell design for a 355V nominal, 22.7 kWhr @ C2 power package capable of outputting 2.4 kiloamps for 10 seconds! The very low voltage sag at high currents is very impressive with these particular cells. Graphs provided by Kokam reveal that for every 5C rate of discharge, the cell sags ~.1V, so beginning at 3.8V if one were to extract 150 amps, the cell drops to 3.7V, and at 10C or 300 amps, it goes to 3.6V, so at its continuous rating of 20C or 600 amps, the cell drops and stays at 3.4V…this is very impressive stuff! In theory, at the 10 second rate of 40C -1200 amps, the cell still hangs at 3V! Do the math for our 2P96S pack, and this equates to a staggering 691 kW! It’s amazing, that 345 lbs. of Kokam cells will generate 926 battery hp! This is terrific power density.

As exciting as the prodigious power density of this pack will be, there’s that other side of things, energy density, that is equally exciting for my street legal EV. With a full 22.7 kWhr @ C2, and with 190 Whrs per mile efficiency, White Zombie’s highway driving range will be a dream-come-true 110-120 miles! Remember, it doesn’t hurt these cells to take them down 100%…they can be taken there 1450 times and still retain 81% of their original capacity! Being conservative and just using 100 miles per 100% discharge, and being conservative and stopping at the 1000 cycle point, this equates to 100,000 miles of driving!

Knowing that my Datsun is a Nissan, it seems very handy for comparison’s sake that Nissan is unveiling its new electric car, the Leaf. Larger than a Datsun 1200 and heavier by more than a half ton - the Leaf weighs 3400 lbs. vs the predicted Zombie curb weight of 2275 lbs., Nissan’s new electric car has a 24 kWhr pack made from 192 flat-shaped cells, and they claim 100 miles per charge. Other early testers have this to say:

“The Leaf sports a 24 kilowatt-hour lithium manganese battery…air-cooled battery provides enough juice to go 100 miles”

“The Leaf, an all-electric five-door hatchback, will have a 100-mile range…driven by a 24-kilowatt-hour lithium-ion battery pack.”

“…said the 100-mile range suggests the car will have a 20-kilowatt battery.”

As with any production factory EV, you are not allowed 100% discharges from the battery’s capacity, so it’s safe to assume those 100 miles are accomplished on anywhere from 20-22 kWhrs. I am predicting 110-120 miles in my smaller car with its lower frontal resistance and that only weighs 2275 lbs. and with close to 23 kWhrs of usable battery capacity. Coincidentally, my old Nissan uses 192 flat-shaped lithium manganese cobalt cells @ 23 kWhrs while the new Nissan uses 192 flat-shaped lithium manganese cells @ 24 kWhrs. …it makes for a very interesting comparison:

Nissan Leaf:

3400 lbs. curb weight
mid-sized, 5 passenger
24 kWhr
100 miles per charge
0-60 in est. 8.5 seconds
est. 1/4 mile ET 17 seconds
top speed 87 mph

Nissan / Datsun 1200 ‘White Zombie’:

2275 lbs. curb weight
small, 4 passenger (2 now due to 6 pt. roll bar)
22.7 kWhr
110 - 120 miles per charge
0-60 in est. 2.5 seconds
est. 1/4 mile ET (at 1/2 power level) 10.8 seconds
top speed est. with ratio changed to 3:50, 135 mph

345 lbs. of these Kokam cells are 59% lighter than the out-going lead acid pack that was comprised of 60, 14.2 lb. Hawker 12V batteries that weighed 852 lbs., but considering module packaging with their built-in copper interconnects, cabling and hold-downs for the 12 modules, as stated, the Kokam pack as installed in the car should be 450-460 lbs. The lead acid pack had 852 lbs. of batteries, but with the copper interconnects, long cabling between the rear seat and trunk areas, the twin string bridging contactors, compartments and hold-downs, the actual lead acid assembled and installed pack weight was 906 lbs. On the surface, it seems the car will lose 450 lbs. or so, but other structural mods to the car adds back some weight. You’ll have to tune in to pt. 4 to get that and other interesting info on how things are progressing.

See Ya…John Wayland

Dow/Kokam Powered Zombie…10s in 2010! (pt. 2)

November 29th, 2009

Hello to All,

Just in time for Thanksgiving, here’s the second installment:

Continued from pt. 1….

After a two year drought seeking lithium, in the period immediately following the Wayland Invitational IV races things really started to happen. Figures, it all happened ‘after’ the races! Oh well, I guess I shouldn’t complain!

It took me a while, but I finally realized that sometimes it takes a team approach to get things done, and that’s exactly the change I made in 2009. I am fortunate to have good friends in the EV community, and many assisted in my efforts to acquire a high power lithium battery maker’s sponsorship. I had been working through Dick Brown to get in contact with Kokam. It was Dick Brown who had acquired sponsorship from Enersys in 2005 when a friend of his was high up in that company. This man, like Dick, knew and appreciated the value of proving a battery’s power and reliability on the race track. Soon after though, he left Enersys and moved on to form Kokam America, becoming the company president. Dick and I were in contact with him about the possibility of a Kokam sponsorship for the Zombie project, months before the WI-IV races. At the same Jim Husted and my new friend Bob Fagliano had also been talking with Kokam engineers about cells for another very high profile project. For those who were at the races and may have met him, Bob’s the guy who had that glossy-black ethonal powered T-Bird at the WI-IV races on display. I had met Bob in the weeks just before the WI-IV races, and we hit it off from the start. If you were at the Wayland EV Juice Bar enjoying the backyard craziness and social time, Bob provided those twin big coolers packed with icy-cold refreshments. Bob is heavily involved with alternative energy - ethonal, electric power, solar, wind, you name it, he’s into it! Like Dick Brown, Bob’s one of those guys who seems to know everybody, and as I’ve learned, he’s a guy who can get things done! Perhaps his best quality though, is that he’s just a good guy.

Bob had also established a relationship with Kokam’s national sales manager. Kokam’s markets have been mostly military and medical, but they have plans to get deeper into the EV market. Stimulus money was looking good for Kokam’s expansion plans to build an 800,000 square foot facility in Midland, Michigan that would produce advanced large format superior lithium polymer batteries for EVs. The sales manager is a sharp guy and saw the value in proving Kokam’s LiPol cells’ power and reliability in a stressful environment like EV drag racing, and he was convinced that showing off the cells in a high profile street legal electric car - not just a pure racing vehicle, was a great opportunity - the White Zombie project seemed a perfect fit. He also liked the whole TV series thing that was also brewing in the background. As it turned out, several of Kokam’s USA based engineers had seen the OPB video and were already hip to White Zombie. During the ongoing conversations and tech talks with the sales manager and key engineers, Dow was ironing-out their their partnership deal with Kokam America. At about the same time we were looking into a very special ‘ultra high power’ type lithium cell Kokam had made for a defense project, the U.S. Department of Energy announced a $161 million federal grant to Kokam for developing a new generation of high-power battery technology for supplying the automotive industry’s electric vehicles. All of the pieces were falling into place.

Bob had been in touch with one of Kokam’s top engineers, who besides being an expert on lithium cells, was very much into hi pro cars. Bob had been talking with him about White Zombie when he recommended the perfect cell for a street legal drag car - a cell with very high power density, yet also a cell with high energy density as well. Could it be, that the Zombie could have both insane levels of instantaneous power ‘and’ have a pack with enough energy density to up the ante in the miles-per-charge game? I had checked out the specs on this ultra high power LiPol cell, and quite frankly, was blown away with the stats!

While doing my daytime gig of wrenching on lift trucks getting beat up and covered in hydraulic oil, Bob called me in the very late afternoon, saying ‘he had something for me’. As it turned out, he and I were both in the same Oregon City area, so we arranged a top secret meeting in the darkened parking lot of Shari’s restaurant, and in the early evening, like some illegal drug deal, we met where he handed me ‘the package’. The box was a flat affair, about the size of a thick dinner tray and weighing maybe nine lbs. I opened it, to find a pair of vacuum-formed black plastic trays stacked together, and inside each were a pair of Kokam ultra high power lithium manganese cobalt polymer cells, looking like square pancakes sealed inside static bags and with two wide metal tabs at the top side. In my trembling hands, I was holding less than 8 lbs. of not-yet-available-to-the-public lithium cells that if connected in series could effortless crank a highway tractor - over and over, while making more instantaneous power than the tractor’s standard 200 lbs. of 8D lead acid cranking batteries!

One thing led to another, and I suddenly found myself in very positive negotiations with Kokam America. I studied the specs of these cells, and the more I read and the more I talked with Kokam’s engineers, the more excited I got over the possibility of getting enough of these to power-up the Zombie! Kokam America’s national sales manager even came to Portland for a face-to face meeting with team Plasma Boy. One of the team’s longtime members is Rich Rudman, who’s steadfastly supplied me with ever-increasingly more powerful chargers, BMS, and track side support from little known weeknight racing outings to full blown NEDRA EVents. Rich has always been there for me. Rich and his Manzanita Micro guys have been working with various brands of lithium and the BMS for it, for years now. Kokam was comfortable that we could handle the BMS to keep the cells alive.

We still had not been given the full go-ahead on cells, but we were very close. After being invited to visit the Kokam America plant in Lee’s Summit, Missouri, Rich and I were on a plane to the Mid-west. To say we were treated well, is an understatement. After a terrific night out to dinner, the next day was all business and a very productive meeting ensued. I wanted to design a modular type system for the Zombie, and the assembled Kokam team agreed with the plan. Kokam added that they would provide engineering assistance with detailed mechanical drawings and all the EE help we might need, As part of the plant tour we received, we got to see the stack of ultra high power cells with a ‘Plasma Boy Racing’ label on the rack! Kokam America had worked with the US Navy on a special limited run of these ultra high power lithium polymer cells they had been developed for helicopter rotor crank duty, one of the most stringent applications for any battery.

Not long after returning home from Missouri, 210 of the special ultra high power cells found their way to Portland…we had our lithium! It’s ironic that these LiPol cells were developed for helicopter rotor crank duty, because the very first version of White Zombie used helicopter rotor crank NiCads! From the June 2009 Design News magazine:

A little more than a decade ago, virtually all racers considered electric vehicles to be glorified golf carts. That began changing in 1994, however, when the Oregon Electric Vehicle Association decided to stage an electric drag race to show the public that environmentally-acceptable EVs could be “fun and exciting.” The organization cordoned off a little street in downtown Portland, grabbed a few stop watches, and laid chalk lines on the cobblestone surface. Wayland, however, was not about to stand for the idea of a genteel, 30-mph drag race. He found the concept offensive; it was as if someone had tried to paint a smiley face on his soul. “I thought about the 72-volt cars that could barely get out of their own way, lumbering and wheezing uphill at 30 miles per hour,” Wayland recalls. “And I said, we can’t show this to the public.” He didn’t. Wayland used a helicopter battery and transformed his Datsun 1200 into a 175-volt race car. “They weren’t expecting cars like mine,” he says now. “Here I came with my Datsun, burning rubber in all five gears and smoking the tires. Women and children were running for cover!”

To see photos of the first time I used helicopter batteries in White Zombie, go here:

Stay tuned for pt. 3 where I get into the nitty-gritty specs and details of these cells, and tell all about the many changes being made to the car to better handle the new power level. How much power did I say? The answer, in pt. 3!

See Ya…John ‘Plasma Boy’ Wayland

Dow/Kokam Powered Zombie…10s in 2010! (pt. 1)

November 29th, 2009

Hello to All,

It’s been a while since I’ve put together a full-blown Waylandesque post, so here’s one coming at you! As I never really got around to writing much about the Wayland Invitational IV races, I’m making this a combined story covering what led up to the races, what happened immediately after the races, and then I’ll get to the exciting stuff happening right now - the late ‘09 tear-down and rebuild of the Zombie that includes the design, creation and assembly of what I consider to be the ultimate battery pack for a high performance street EV!

From Rod Wilde:

>I can’t wait! It will be Sunday in less than 6 hours :-) I have been a bit >bored lately and could use a Wayland tale for a lift in spirits.

OK Rod, there’s a lot of details to follow, so kick off your shoes, grab a cup of hot coffee, and sit back and enjoy the tale…

From Rod Hower:

> I always read your posts on this list, but I might have missed one about the >details of your ‘most potent ever’ White Zombie. Inquiring minds want to >know what’s up your sleeve.

No, I haven’t really talked too much about this, but since you asked…it all started like this:

Ever since tasting the forbidden fruit more than two years ago when we borrowed the spare A123 lithium pack from the Killacycle team, I have been engaged in a quest to get lithium for White Zombie. As some will recall, in the Summer of ‘07 we pulled the heavy 852 lb. lead acid pack and dropped in the 374V, 6.9 kWh, 880 cell assembly that once powered Killacycle. It was the smallest of the three different lithium packs used in Killacycle. The 880 cell pack was the first one, then the team pulled and replaced it with a new pack at 990 cells, and now the current pack is at 1210 cells. With the heavy lead out of the Zombie and a tiny 175 lb. pack of lithium replacing it, the curb weight fell to around 1900 lbs.! Though the A123 pack didn’t quite match the fives time bigger 1500 amp-capable lead pack, the suitcase sized package of cordless drill cells still cranked out an amazing 1400 amps! Minus all the lead weight in the back seat and trunk areas, the car had a poor launch and excessive wheel spin that occurred throughout the entire run - even still, White Zombie still posted an 11.4 @ 114 mph ET. If we had more time to experiment with controller settings, tire pressure, and driving techniques, Tim, I, and most everyone else who were there that night, knew that the lithiumized Zombie was a high 10 second runner! Once the car ran broke through the 11.5 second barrier however, without a roll bar system and a fire suit for Tim (NHRA and NEDRA safety rules), we were politely escorted off the track and were not allowed to make any more runs. The next day, Sunday, we pulled the feisty A123 pack from the Zombie’s trunk, and with a tear in my eye, handed it back to the Killacycle boys :-(

Following that exciting July weekend, it was tough going back to 852 lbs. of lead :-( Even tougher, was installing a six point roll bar system knowing it would add close to 100 lbs. to the car! The Zombie’s curb weight ballooned to a porky 2660 lbs…by today’s standards about an average weight for a compact car, but for a 70’s economy car that used to be just under 1600 lbs., way too heavy! Even so, with the lead acid pack unleashing its full 1500 amps, in August at the NEDRA Nationals 10th Anniversary races WZ turned in an 11.882 @ 109.58 mph, the quickest ET it had ever run on lead acid - considering the amount of weight to move, not too bad! Back at PIR one week later at the ‘Street Warriorz’ drag races, the Zombie had launched hard carrying its front tires more than 100 feet as it walked all over a hot Corvette Z06. Looking at the timeslip’s 1/8 mile stats the Zombie was on its way to an 11.7, but damage to the Siamese 8 in the last 500 feet wiped that notion away as Tim shut the car down and it power-off coasted to a 12.07 ET :-(

As positive as 2007 was, most of 2008 was anything but! The problems started with motor parts delays, then there was the EVDL censorship nightmare that led to soured relationships and the cancellations of both the Wayland Inv. and the NEDRA Nationals in Portland. In spite of the troubles, I was busy all through 2008 trying to get lithium sponsorship on many levels. The l-o-n-g delay in the airing of the now infamous OPB ‘Electric Drag Racing’ video that we had put a lot of effort into and had hoped would be a catalyst for sponsorship, only contributed to the sponsorship drought. The EV drag racing story kept getting bumped off OPB’s play schedule, there was nothing new to show potential sponsors, and nothing materialized while the Zombie sat out the 2008 racing season.

After shelving it for a year and a half, in November of 2008 OPB finally aired the story in their weekly show ‘Oregon Field Guide’. To the surprise of the series’ executive producer (who had held its airing back) it immediately went viral. In fact, in their ‘20 Years of Oregon Field Guide’ three hour long anniversary celebration show aired at the end of the year, the show’s executive producer went on camera to announce that our EV drag racing episode had been was unofficially voted the #1 Oregon Field Guide video of all time - unofficial because it was aired too late in the year to be in the list of shows to vote on, yet the votes still piled in! In a few short months, there were over one million views at the OPB on line videos page! The OPB story was followed with the December 2008 release of the center fold-out feature story on my twin 1200 EVs in the Jan. issue of ‘Retro Cars’ magazine, and the media frenzy continued into 2009 with lots of interest pouring in - including being contacted by numerous network TV series producers who, inspired by the OPB video, had ideas for a Zombie-based TV series…more on this to follow.

In the early Spring of 2009 I was negotiating with an LA based TV series creator, who understanding the importance of having powerful lithium batteries in White Zombie, was making follow-up calls to prospective lithium companies on my behalf. I was getting closer to a lithium deal, and was ‘really’ hoping to have a lithium pack installed in the Zombie in time for this past Summer’s WIIV races - alas, that was not to be.

In July, with the EV drag races bearing my name about to happen, a White Zombie no-show was not an option, so I swallowed my pride and accepted the fact that the car would run slower than it had in the past. Tim and I resurrected the nearly three year old Hawker lead acid pack by initially pulling and replacing eight weak batteries, thanks to generous help from longtime friend and past sponsor, Dick Brown, who had scrounged up and sent eight new Hawkers to me just in time. It was Dick Brown who had gotten me sponsorship from Enersys (Hawkers) when a friend of his was high up in that company. Tim and I went through the pack that had little exercise during first half of ‘09, save for a few EV car shows and an occasional 10 mile run & recharge. We found that the majority of the batteries were all sitting at 12.6V or so, but we did find eight of them that were bad. It was ironic that we found exactly 8 bad ones, when Dick had sent exactly eight news ones. Through various techniques, we got the new batteries pretty well matched in SOC with the old ones, then we reconnected everything back into the twin 360V string affair it had always been. I took progressively longer trips followed by recharges for a few days, and the pack seemed to be getting stronger and stronger.

Hoping for maybe mid 13 runs so as to not be too embarrassed, the Zombie surprised us all when Friday night when it broke out of the gate with a 12.694 @ 96.7 mph! The ET was better than I had hoped for, but the low trap speed had me concerned. When Tim returned to the pit, we could see a mist on the Lexan cover for the back seat area portion of the pack…not a good sign, and we both knew the pack was in trouble. The second run came in slower at a 12.996 and just 89.60 mph, so before the car came back to the pits I knew what to expect. This time, the Lexan was fully drenched from what I thought were numerous batteries letting go…we were done for the night. I told Tim that we had made a good showing for what we had to work with, and said we’d just be good hosts Saturday.

The drive home from the track with fully exercised and hot batteries is usually one the Zombie can make on the freeway at a good clip all the way - this was not the case Friday! I felt the pack going soft about 2 miles shy of the Wayland EV Juice Bar and had to pull over as the pack was sagging lower and lower. I had to be towed back by my crew, and I was now fully convinced the pack had done its swan song and would never power the car again.

The next day during the crazed afternoon Wayland EV Juice bar activities with a congress of Teslas, a Tango, Crazy Horse, and all the other EVs being either recharged or repaired from Friday’s racing strewn all over, Tim was inside the Zombie quietly checking out the carnage… the idea of sitting out Saturday night’s track action wasn’t part of his plans! Though I was convinced the tired old pack had thrown in the towel, Tim talked me into joining in the post mortem exam. To our surprise, only ‘one’ of the old batteries had caused all the trouble, and it had let go in a spectacular fashion and was totally open-circuited. ‘Now’ I understood what had been going on during both runs and why the trap speed was so low…with one string having the troubled battery in the loop, that battery’s initial high resistance made the string weak, then when it fully opened, it essentially took the string out of the picture entirely. The resultant good string was doing all the work, and sagging very low while doing it…low volts equates to low trap speed. This also explained why the car felt so strong for about 12 miles on the way home from the track, then simply took a dive…it was running on only one string all the way home. All of this was verified, in that the batteries in the good string were very heavily discharged - but they were all very ‘evenly’ discharged and all sitting at a stone dead 11.9V. I had gotten lucky we didn’t reverse cells in a few batteries! The batteries in the string that went down with the one bad battery, were all nearly fully charged…proof the Zombie had been running on just one of the two 360V strings, and still managed to run 12s!

Fresh out of new Hawkers, I rummaged through my forklift service truck and found an old spare Hawker that had seen rough service, thought ‘what the heck’, and after getting it charged up, put it in the pack that had the weak battery, as the rest of them were fully charged. I did a replay of the ’short trips followed by recharges’ and the pack seemed to be OK. Because of Tim’s failure to give up attitude (why he gets to be the car’s driver) the Zombie would return for a second night of racing!

We weren’t the only team with technical problems. After the extreme effort and exhausting drive from Anchorage to Portland, the Crazy Horse Pinto team of Mike and Hank, like us, had problems at the track Friday night. They felt their problems were in part, caused by a weak battery in their traction pack. Side bar….though we’ve tried many times, we’ve never had a good solution for the Zombie’s 12V system, as DC-DC converters seem to die in the application…something about a wildly-swinging supply voltage as high as 450V at full charge and a low of 180V at full discharge racing currents plus demanding high reactance contactor coils seems to take them out! Thus, the Zombie has had a sub-standard 12V system simply supplied by an unassisted 16 ahr Hawker battery - exactly like the traction pack units.

From Ken’s post ‘Frustration’:

>Another major part of that frustration is Hot Juice Electric projects that I >can’t get to. Work on the Chassis Juicer has not been touched in over six >months! I feel awful about that because I promised John Wayland a Chassis >Juicer for the White Zombie. It was promised for the Wayland Invitational >and it is still not done! Please wait… Pardon me - I had to go scream.

Knowing our racing friends from Alaska needed a Hawker, we pulled the healthy under-hood 12V Hawker and gave it to them to get the Pinto back on its game. Thinking we could get by with one of my ‘50%’ type extra Hawkers on the shelf, we grabbed one and replaced the one we pulled for the 12V system with it. I figured recharging it hard between runs at the track would help it keep up. At the time, I was wishing Ken had brought a brand new beta unit Chassis Juicer for us - but he didn’t :-( It was sure great to have Ken and Heidi at the Wayland EV Juice Bar just the same :-)

Back on the track Saturday night, the pack was acting like it had two years ago, and the first ET of the night was a surprising 12.418 @ 100.7 mph! There were no indications of battery problems at all, and the Lexan stayed dry and clear. The 2nd run was even more impressive, almost dipping into the 11s with a 12.073 @105.53 mph! Wow, we were on track to run an 11 the next pass! Remember that 50% 12V under-hood battery? It raised its ugly head and bit us in the ass when on the 3rd run contactor dropped in and out, and the pass came in at 12.468 @ 102.11. The 4th run had even more sagging 12V system problems, this time not having enough juice to pull in the parallel contactors and rebooting back to series mode for the entire 1/4 mile run that came in at 13.804 @ 87.43 mph. Oh well, we gave it a good try, and our best run was only 2/10s off from WZ’s best lead acid ET two years ago when the pack was fresh, with an 11.882 @ 109.52 mph. A pretty respectable showing, enough to stay well ahead of my new Tesla friends, and a wonderful final curtain for the mighty Hawkers!

Stay tuned for pt. 2…

White Zombie featured in Wall Street Journal

August 2nd, 2007

Plasmaboy in the Wall Street JournalJohn J. Fialka writes an in depth article about the John Wayland, NEDRA and the history of electric drag racing for the front page of the Wall Street Journal. Don’t miss the excellent video in the middle on the on-line article.

PORTLAND, Ore. — On a recent Friday night at the Portland International Raceway, John Wayland scanned the dragsters, looking for an opponent for his geeky looking 1972 Datsun sedan. Finally, he challenged the owner of a souped-up 2005 Corvette, the hottest-looking car at the track, to a quarter-mile race. See how an electric car dubbed the White Zombie is leaving conventional muscle cars in the dust. When the starting light flashed, the Datsun, known as White Zombie, shot silently past the Corvette and kept widening the lead as the two cars faded into the distance…

11s in ‘07…Timing is Everything! (pt 2)

July 24th, 2007

Hello to All,

The above title now seems at odds, as I finally get this part 2 post out. The timing for it sucks. By now, everyone knows that another EVent has come and gone (Wayland Invitational III) and I should be writing about ‘it’ instead. Oh well…chalk it up to being over-the-top busy the past three weeks, chalk it up to just being plain wrung-out from all the ups and downs of putting on a major racing EVent, chalk it up to being worn-down from weeks of constant media attention more fitting of a visiting Hollywood super star than some Greek geek playing around with his electric car. On the other hand, to fully appreciate the July 13th & 14th weekend’s track numbers you really need to know the build-up to the Wayland Invitational III, which our racing from June 29th was very much part of.

Anyway, here it is at last, part 2:

11s in ‘07…Timing is Everything! (pt 1)

July 6th, 2007

Hello to All,

As usual, there’s a Wayland story here, so go get that cup of coffee and maybe a nice cinnamon melt, kick off those shoes, relax, and enjoy!

All I can say, is WOW! Finally, we’ve broken into the 11s that have eluded us for now for the past two years….and yes, we drove it to and from the track! As Rod Wilde posted, Tim Brehm drove White Zombie into the 11s twice, with the fourth run the best ET at 11.948 @ 109.75 mph, and the fifth and final run an 11.960 @ 110.14 mph. Remember when we were trying to be the first street legal EV to crack 100 mph in the 1/4 mile? Geesh, now we’re flying up to 110 mph!

White Zombie 11s in 07

July 6th, 2007

Hello everyone,
After many hours of work on the car to get ready for racing, Friday finally came. It had been raining off and on all day with downpours in the afternoon. It was starting to look like the anti-EV vortex was back. I arrived at Wayland’s around 4:00 pm to find the shop full of cameras and crew interviewing Wayland. Between the weather and the distractions it wasn’t looking good for racing.

Siamese 8 Lives Again…Seattle here we come!

June 21st, 2007

Hello to All,
Before getting into my post here, I want to publicly thank my friend Jim Husted for his heroic effort in rebuilding & improving the Siamese 8 these past weeks! Jim is ‘THE’ DC motor king! His artistry is amazing. I had the motor in the back of my work service truck yesterday in all its purple glory, and the ‘wows’ it got from all those who had the pleasure of seeing it, told it all. Thank you, Jim!

OK, here we go…..Advancing motor timing as you increase the volts to the motor under high amperage has been long known for its benefits, so it’s nothing new. Read the rest of this entry »

Mike’s Pinto Project & Gear Ratios

March 27th, 2007

Mike Willmon wrote:

So another question for the list. Since welded gears are not EVen allowed under NHRA rules and spools are only allowed with aftermarket housings, whats the strongest type of locking differential to get for drag racing? Detroit, Auburn, ARB (are ARB Air lockers EVen strong enough for racing?)?

I think they’re all pretty strong. I love the Detroit Locker in White Zombie. Not a lick of problems to report, and it simply goes about its business. In a quiet EV, it’s pretty cool because you can clearly hear the locker ratcheting and clicking as the car turns, then when you line up straight on the strip launch pad, it goes ‘Ka-clunk!’ as if to say, “Yeah, I’m ready to help you paint twin blacks stripes.” The Detroit has taken all the power the Siamese 8 has twisted into it and has easily handled the torque. I would highly recommend one. Read the rest of this entry »

Re: Mike’s Pinto Project

March 27th, 2007

MIKE WILLMON wrote:

My next concern is the strength of the assembly housing itself.

I see John’s mentioned going to a built aluminum carrier (and maybe a whole aluminum housing)

Mike, the new ‘Strange’ aluminum third member has arrived, though I haven’t picked it up yet. I am not going to an aluminum housing for the rest of the axle setup though. I am very pleased with the Dutchman Motorsports steel ‘Street Strip’ housing and have had no problems with it at all. In addition to this new aluminum third member casting, a new ‘Wilwood’ drag raging disc brake conversion setup has also arrived. These are specifically designed for drag racing, are extremely light weight, and for a little Datsun 1200 are huge at 11.3 inches. Together, these two changes should chop another 50-70 lbs. weight off the car, and the having four wheel discs will certainly make the car haul itself down from 110 mph quicker.

After Sunday’s foray into flash-over motor volt limits, I’ve decided to do another gear ratio change, too. More on this later.

John,
Aside from the cracks around your pinion shaft carrier, how did the chopped assembly housing from the ‘57 Ford hold up to the abuse?

Very well. I had no problems at all with the stock housing. The only complaint, was that chopped as it came to me, it placed the third member off to the passenger side too far. By the time the Dutchman would have been finished modding the housing and its two axles, it was not a lot more money to simply start over with the ‘Street Strip’ housing fitted with the big bearings and the beefy 31 spline Dutchman axles over the stock 28 spline ones.

Live from PIR, Fireball Incident (as told by Roderick Wilde)

March 18th, 2007

John, Tim and White Zombie went for a day of racing at Portland International on Sunday. No post from John yet, but here are a series of posts made by Roderick Wilde to the EVDL.

3/18/2007 1:19PM

John has been calling me from the track so for those very few EV race fans out there here is an update. The first run on the new batteries with the current turned down to a measly small street amps of 1000 it turned a 12.64 at 98.69 mph. The 60 ft time was 1.67 and it was at 84.5 mph at the eighth mile at 7.85 seconds. The second run netted a 12.38 second ET at 104.21 mph. Of particular note is the fact that in all of last years racing 104 mph was the top speed they ever got out of “White Zombie”. They have a great announcer at Portland International Raceway that is really playing up the fact that this is an electric car and also the specs on the car. The first two runs annihilated the cars in the other lane. The second run was against a built V8 Chevy Nova. The poor guy didn’t have a prayer being matched up against the electric. On the second run he was at 87.73 mph in 7.74 seconds. With these leaps in performance they just may get into the elevens without turning up the amps. I personally believe this type of publicity does a lot for the cause of EVs. People at the track go home and tell their buddies, “hey, you wouldn’t believe what I saw at the track last night!” The word is definitely starting to get out there and with the Car and Driver article EVs may become part of the general population’s consciousness.

450 HP in 60 little Orange Boxes!

February 19th, 2007

We have a new slogan at Plasma Boy Racing….11’s in 07!

I’m happy to report that Dick Brown (Aerobatteries) pulled through again for us this year and working with our sponsor Enersys, our new 40% more powerful batteries have arrived! This year White Zombie will again, be running on Hawker power, but instead of the 30 - 24.5 lb. 26 ahr Aerobatteries models we used last year, we will be using 60 of the smaller Genesis model 16 ahr batteries. Yes, these are nearly the same battery we ran with from ‘98 through ‘02, back when White Zombie had 28 of them making up an ultra-light 378 lb. 336V battery pack. Before they had been abused and super-heated to extreme hand-burning levels, we could pull 750 amps from them with very few failures. Even 800 amps was doable for less than 10 seconds. Yeah, we did blow quite a few of them up as the years were added on, but again, they only began to fail after substantial abuse. Details for those interested, can be found at the Plasma Boy web page…just click on the ‘White Zombie History’ button and scroll to ‘1998 Early Version’.

Car and Driver EV Racing Article Debute Delayed

February 14th, 2007

Hello to All,

I had been assured by the editors at Car and Driver, that the anticipated EV racing story was slated for the April issue that’s about to hit the stands in the next week or two…then I got the phone call. For whatever reason, the story got bumped I’m now told, to the May issue :-(


It was sad news for me, as White Zombie is returning to the Portland Roadster show this year and will be on display at the Oregon Convention Center March 2nd, 3rd, and 4th. With the April issue to be on the stands at the same time, the timing ‘was’ perfect! There’s nothing better, than to have your car in a BIG show while at the same time, it is featured in a major magazine…. oh well.

The good news, is that Bill Dube’s exciting Killacycle is in the current April issue of Hot Rod magazine! Congrats to Bill and the crew for their recent success.

See Ya…..John Wayland

John and Ted’s Excellent Adventure…Delivering the Mail!

August 31st, 2006

Back in July I had written:

Sob….though I’ve been in, under, and all around GP, I’ve never had a ride :-(

That’s all been changed. With all the current talk about Gone Postal, instead of ‘talk’, I’ve been out driving it! Yeah, the rad postal van sits behind the locked gate here at the Wayland EV Juice Bar as I write this. What a beast it is!

I got to take it home after Saturday night’s racing, a calm and get-to-know-one-another 16 mile drive back home….just me and GP. It helped take my mind off the fact that I had just relinquished control and possession of White Zombie to FT and Roy to send it halfway across the country to the RPM trade show. Arriving at my backyard EV shop, I stuffed lots of juice back into all 40, yes, count ‘em, all 40 of the thirsty Exide Orbitals. I topped the twin-twenty 240V packs off the next morning before taking it out for a spin.

Going out the back door of my neighborhood onto a wide open road, with the front drive in 2nd gear and the rear drives kicked in, at around 20 mph I decided to stomp on it and see just what this machine had in it….OH MY GAWD!!! Instantly, I had my hands full, as the full fury of twin Zillas, twin 8s, a pissed off 9 in front, and 40 warmed up and rock’n Orbitals simply mauled me up to perhaps 50 mph in, what, maybe a second??? The torque was massive and it felt as if I was riding a bull trying to buck me off! Where White Zombie feels brutal, this thing feels possessed! If the forces behind this project ever get the planets all aligned in just the right order, I have no doubts that this 4300 lb. brick monster can run low12s (perhaps a high 11) and an easy 115 mph.

Reversing White Zombie

August 28th, 2006

OK, it’s Monday 5:57 am…cobwebs are clearing, the day after day 3 of a crazed weekend of racing and fellowship with the best of friends.

In response to Jim Husted’s first part of his Late Night Nationals post, James Massey wrote:

So how did John do reverse in Zombie? Did he go with the tried-and-not-so-true reversing contactors that he had trouble with before, or do something less conventional?

C’mon, wanna know…

James has been great helping me with ideas on the best way to reverse the not-so- conventional motor & contactor setup in my car, so I want to thank him for all his support. In the end, I went back to the way I had done it two years ago, only in a much more aggressive design. To clarify, I reverse the front motor section only while the rear motor section is off line and is just along for the ride. Here’s how it gets done…

Much to my not wanting to do so, I replaced the beefy 4/0 external field-to-armature cable connection (~ 1ft. long) on the front motor section, with two short 4/0 cables and an SW200 Albright contactor with a single set of contact tips normally open (NO), the same model as the three I use for the series/parallel switchers. The racer in me was convinced the added extra set of high current contacts would add too much resistance and negatively affect the car’s performance at the drag strip. When you’re hunting 100ths of a second, even small losses affect things.

Fast forward to this weekend’s runs…the car ran 12.3 ETs, the same as before the reverse mods, so I’m happy to report that I was wrong :-) , and boy is it sa-weeeet! Flip a switch, and it silently goes the other way!

Back to the reversing project…In my car’s original design, I wanted to avoid using the array of F-R type contactor sets used for series, parallel, forward and reverse (times two) as is the norm for a Zilla equipped EV that takes advantage of its ability to drive twin motors. From my extensive experience with forklift contactors, I’ve learned that despite claims from contactor manufacturers to the contrary, the F-R contactors burn their normally closed tips that rely on spring pressure much worse, than their normally open tips that are closed under high pressure via the magnetic pull of the contactor coil. In White Zombie running at 2000 amps, all those spring-closed tip sets add up to unwanted problems. Thus, the way I wire the sections of my Siamese 8 requires just three single pole type contactors (NO tips) to accomplish the series and parallel modes. For the series mode, just on SW200 slams shut and connects the motor sections in line for the high torque series configuration launch mode. To switch to parallel, the series contactor opens and a pair of parallel SW200s slam shut connecting the motor sections across each other for the parallel configuration max hp top end mode. Simple, and no NC spring pressure contact tips, and just three easy to see and easy to replace NO contact tip sets, and after two years in service they look almost as new still! To continue…with the 4th SW200 inserted between the field and armature of the front motor section’s field-to-armature series connection, with it energized and pulled in I can still operate the Siamese 8 motor as I had been doing, or, by opening this ‘field contactor’, the front motor section can now be reconfigured for reverse via a set of 300 amp GE single pole NO contactors. These are the same heavy duty contactors I had installed and experimented with for field weakening. Yes, in the forward direction series mode of operation, the Siamese 8 now has two SW200 Albright contactors to loop the 2000 amps through instead of just one, but when I looked at the tip condition of the series mode contactor and saw they had not burned at all the last two years in service, I figured there must not be all that much resistance to worry about, and the results from this weekend’s runs backs this up.

Soooo…that’s how reverse was accomplished, at least from the high current high voltage path perspective. The other ‘control logic’ circuit is a whole ‘nuther story! I wanted to use the Hairball’s great set of convenience and safety features, especially the ‘roll detect’ circuit Otmar built into its design (inspired by yours truly back in the formative days of the Hairball) that prevents catastrophic reversing of the motors during an apposing direction under detectable rpm. I also wanted a true ‘Neutral’ direction position with the dash mounted three position toggle switch, so that nothing can run when the switch is in neutral. I also wanted all the fault code options intact….etc. etc.

The high current reversing wiring was actually completed a week ago and had been tested in a crude ‘disconnect all these wires, hook up all these’ wheels off the ground trial operation. The control logic job was intense and required lots of new wire looms, a lot more relays, more switches, a new bracket, and more stuff too boring to keep listing. Tim Brehm and Chris Brune literally sweated through a day long under-hood ordeal getting it ready for racing Friday night while I hung out on the shaded deck sipping lemonade through an interview with Car and Driver’s Ted West. Thanks to both of these guys for taking on the challenge and taking the pressure off me.

In the end, it all worked as planned…..oh yeah, there ‘was’ that little glitch of frying 25 amp fuse! Seems the last minute snubber we installed across the reversing contactor coils couldn’t handle the inductive kick-back and failed in a shorted condition! Once we figured that out though, reverse was available at the mere flip of a switch…beautiful!

See Ya….

Car and Driver Runs 12.3 @ 103 mph in White Zombie!

August 26th, 2006

Yes, it’s crazy time here at the Wayland EV Juice bar… a hot 90+ degrees, people and EVs everywhere! A more detailed report will follow after this weekend’s behind me, but for now this update.Tim warmed-up the Zombie with two 12 second runs, then it was Car and Driver’s Ted West’s turn. The nervous journalist received last minute instructions from Tim and I on the best launching techniques and what to expect before he was strapped into the electric Datsun from Hell and sent out to the track. First run…12.6 even after letting off the throttle too early with the finish line still ahead of him. With his head hanging in shame, he vowed not to repeat the error and delivered smack-down 12.3 @ 103 mph second run. Third run 12.3 @ 102 mph. This last run Ted lifted both front tires about 4 inches off the ground immediately, so the front wheels were stationary and not rotating for about 40 feet…a very cool looking power-launch!

Earlier this year, Car and Driver road tested a new 500+ hp V10 Dodge Viper that turned a 12.5 ET, so it’s now fairly official from the magazine’s perspective, that an electric street sedan runs a quicker 1/4 mile!

One additional stat…White Zombie ran 12’s on all runs defeating every gasser challenge of the night!

Gotta go…time to head to the track.

See Ya…

Oregonian Reporter Gets Zombied!

August 15th, 2006

There’s been a frenzy of media coverage lately over EV drag racing, and in particular, over White Zombie’s routine weekend drag racing runs against the gasser boys. A certain well known car magazine has been in contact (can’t release details right now), Dateline Australia was here, and last night a reporter from Oregon’s biggest newspaper ‘The Oregonian’ spent time with me and the little Datsun from Hell.

It seems that the battery problems we had at the Wayland Invitational a few weeks ago where we blew up a Hawker, are behind us now, and it was just one weak battery that let go. We had replaced it with a pre-cycled spare Hawker and had carefully worked the pack back up into equalization with numerous 10-15 mile road drives, long low amperage charging, then several high current discharges and heavy charge cycles. We raced this past weekend and got four 12 second runs in without a single battery problem. Following Friday night’s racing, I’ve been driving the Zombie every day and the 360V pack of Hawkers are beautifully equalized and sit at 392-393V. They’re rock’n hard and are performing at high levels of power.

Fast forward to the best part….Oregonian sports writer Doug Binder’s ride in White Zombie. So….I’d been trying to explain to him the way the car launches from rest and how even against really powerful gas cars known to run 0-60 in 4 seconds or so, my EV is 4-5 car lengths ahead of them at 60 mph. I told him the Zombie’s 0-60 time is estimated to be somewhere in the mid 3’s. He’s a nice guy, so no disrespect is intended, but I just don’t think he got it. He evidently, had no idea what the car would really be like.

Anyway…it was a hot day, so the recently repaved asphalt on Burnside was warm and sticky. We rounded a corner and just when I had straightened out the Zombie and was rolling at about 5 mph, I planted my right foot down hard! To my surprise, instead of the usual 100 feet of constant wheel spin and copious tire smoke, the damn thing simple stuck and did a wheel stand, instantly slamming the poor guy into his seat as both his eyes were big as saucers as he was now looking through the windshield at the sky instead of the road. When the front end came back down, it unloaded the rear tires a bit and they were breaking loose and squealing as we rushed up to speed. It was about the best power demo I could have hoped for! He was at the same time, in a state of shock, scared absolutely sh….tless, and yet, had the biggest EV grin I think I’ve ever seen…well, OK, Matt’s was pretty big, too! I almost felt bad, because he was shaking a bit afterwards. He told me he had never, ever been in a car that accelerated like that…ever! He said it was more like an amusement park ride :-)

The best news for the Late Night Nationals coming up the 25th & 26th next weekend, is that the article will be the lead feature on Thursday the 24th the day before the races, in the Oregonian’s sports section…great pre-race PR! An Oregonian camera man is scheduled to be at the Wayland EV juice bar this Sunday to take the photo that will appear. I think a line-locked full tire burn is in order.

I can hardly wait to read Doug Binder’s write-up.

See Ya…

Fun at the Movies…Chris Paine meets White Zombie! (pt. 2)

July 19th, 2006

Hello to All,
From part 1…..

At a little before 7:00 the line formed to go into the theater, so show and tell was over and the real show was about to begin.

I was excited to see this movie. In a past life of getting on airplanes and flying into various parts of the country to work in wafer fabs as a high tech trouble-shooter, I found myself in California and Arizona often, two places where the elusive EV1 could actually be seen touched, and yes, even driven if one was fortunate enough. I drove EV1s in San Diego, and I drove EV1s in Phoenix. Though not nearly as lucky as those who were leasees of EV1s, I did get to drive perhaps twenty EV1s over a period of maybe three years. I got to see the Impact, too, the forerunner of the EV1, and got to see and sit inside ‘Sunnyside Up’, the race prepped EV1 that went 183 mph and set a world speed record for a production electric car. Rod Wilde raced drag raced his Maniac Mazda against this car and beat it (to the dismay of the GM engineers) while we were both in Phoenix. I’ve even drag raced White Zombie against Marvin Rush in his EV1…what a fun memory that is (video up at Plasma Boy Racing). I loved the EV1, it’s truly one of the world’s great cars.

Sidebar…

During its heyday, an EV1 was available for rent through ‘EV Rentals’, a subdivision of Budget Car Rental. I took advantage of this, and got to know the good folks at the LA Airport’s Budget Car Rental well. Whenever I had business in that area, instead of flogging some wheezing econocar gasser and adding to the LA Basin’s pollution problem, I was whirring about in a high performance electric car, the fabulous EV1 (driving experience story at the links page of Plasma Boy Racing)! When I first heard of the idea that one could actually rent this rare and exotic car, it seemed too good to be true, and it reminded me of the tales told by aging hotrodders of a time when the legendary AC Cobra, an ultra hi performance muscle car, could be rented from ‘Hertz Rent a Car’. Today, any sane hotrodder would give his left arm for a chance to get a ride in a for real AC Cobra, so to think that ‘anybody’ with a driver’s license could merely waltz into a Hertz Rental facility, drop down some pocket change, and go out and wreak havoc on poor saps in their Mustangs, GTOs, and Vettes, is well, the stuff that makes great stories! Of course, an original Cobra is a highly valued, rare collectible that broke all the rules, set the bar high, and today represents a time gone by. At the time, I remember thinking that some day, aging EVers (guys like me) would tell tales of how one could rent an exotic, rare, limited production, hi performance EV1. Today, the EV1, like the Cobra, is a highly valued, rare collectible (for museums that hide them away when GM tells them to) that broke all the rules, set the bar high, and today represents a time gone by. Back to the movie….

Before the movie began, Chris addressed us all, which really added to the whole thing. All I can say, is WOW! Chris and all involved did a terrific job.

The film is expertly crafted with great camera work and full fidelity, well mixed audio. A highlight for me, was music by Joe Walsh during a drag race scene between a Hummer and an EV1. Other highlights was seeing lots of folks I’ve spent time with either in person or through correspondence, from Chelsea Sexton involved with the EV1 program (she and I hung out together, then she handed me the keys to an EV1 in Phoenix and told me to go play with the car), to former GM CEO Robert Stemple (wrenched on EVs with him in Orlando), to Iris and Stan Ovshinsky (had a wonderful discussion about NiMH batteries with them at EVS 14), to Alan Cocconi (met him one night in the Arizona desert), to Dough Korthof (traveling through Oregon in his Honda EV Plus), Wally Rippel (his first EV was a Datsun 1200)…it was like I was ‘part’ of this movie and that I had lived through the whole thing with everybody. Yes, there are parts of this movie where I thought I might be offended, such as the areas dealing with politics, but it was handled in a way that didn’t seem to be ‘bashing’ for bashing sake, rather, it was dealt with on a factual basis that left the viewer feeling it was up to them to decide…good job, Chris. So great was this movie, that my eyes welled up several times (I can’t say tears for fear of ridicule by male compatriots) during certain scenes. Imagine, a documentary with this kind of power! Even if one is not already an environmentalist or EVer, this movie would move them as well.

After the lights came back up, it was open forum question and answer time with Chris and others. A proud moment for me, was when all those who had electric cars were asked to stand, where we received a huge round of applause.

After the show, Chris was the ultimate host, handing out large format posters and autographing them for all who asked. When the time was right (no, this is not a Cialis commercial), Chris and I had a great one on one discussion about the film. We discussed our mutual appreciation of Joe Walsh where I learned Joe was an EV1 leasee…didn’t know that! Walsh normally does not allow his music to be used in movies, but he was happy to give permission for use in this film. Too much to cover in this area, but let it suffice to say Chris and I had lively conversations as the night went on.

As things were winding down, Chris and friends joined us back outside for the anticipated Zombie ride…or should I say rides? Tim was instructed by my wife to not get too crazy on the streets, while I was standing behind her silently mouthing ‘NAIL IT’. Chris asked for his life to be spared…too bad no video footage was shot of all this fun. It wasn’t the best setup for a full blown Zombie experience. The Hollywood district of Portland is very congested with cramped streets, lots of traffic, people everywhere…you just can’t do 100 mph down Sandy Boulevard! Tim left with Chris and disappeared into the night for a good 15 minutes, while we all worried that maybe they had wrapped themselves around a telephone pole somewhere. They returned though, and Chris’ EV grin was pretty large! I would later see lots of 30 foot long tire patches in the area where they had been. Chris said he could only imagine what the car could do if they hadn’t had such a tight area to drive through. We did see Tim launch the car once as they were leaving a stoplight, and the front tires popped off the ground a little, so at least Chris got to feel that gut distorting torque :-) As he got out of the car, one of the first things he said was, “That does it, I’m coming back for the Portland EV Drag races in August!” In my head I said, “Mission accomplished!”

Remember how I had described how hungry Cheryl, Tim, and I were ‘before’ the show? Since then, only the late afternoon ice cream bars, the hype of the car show, the movie, the high octane discussions, and a couple bags of movie popcorn and a couple bottles of pop had sustained us. To my delight, Chris asked if we would like to join him for dinner at a brew house around the corner that his brother knew of. Yes, there’s a Portland connection to Chris, in that his brother lives here! As I was feeling ‘special’ to have had the personnel invite, it suddenly became apparent that Chris had tricked me with an ulterior motive, as he scrambled back into White Zombie for a ride to the restaurant :-0 Jay Donaway, Cheryl, and I got in Blue Meanie and followed. The pack was sitting at 152V static after the 6 mile drive without a refresh charge, and while the moment of all the excitement this evening had brought still had me zinging, I was also pondering the all uphill drive back to the Wayland EV juice bar on 6+ year old batteries that were already pretty darn tired. Would we make it back home? In the old days, circa the early 1980s, through periods of battery experimentation, there was many a night where Cheryl had to either help me push this car, or worse yet, had to walk home from some ‘stranded’ location with me. To this day, even after having Red Beastie with its easy 120 mile range that never, ever left us without adequate range, she’s still gun shy of the ‘little blue car’, and the first words out of her mouth were, “We’ve got enough to get home, right?” In my head I said, “Geez, the batteries are 6 years old, they haven’t been charged, it’s all up hill home, they’re sitting at less than 12 volts right now with no load on them, what do YOU think?”…but outside that strange head of mine, this came out, “Sure sweetie, the car’s doing great. Relax, let’s enjoy the evening.”

At the restaurant/brew house, the fellowship was fun, and the brew and food was terrific as well. In trying to get a Chris Paine quote describing his Zombie ride, Jay came up with ‘Had I ridden in White Zombie before I made this film it would have been changed to ‘Who Saved the Electric Car?” This brought out laughter from Chris and all.

Afterwards, Chris asked me how the charge was on White Zombie, and if there was enough to give a few more rides for his brother and friends and still get us home OK. Tim reported that the pack was quite stiff still and that the voltage was still hanging near 180 or so. And so rides, we gave! One of Chris’ friends was in the passenger seat and was talking to Tim about how he’s got this buddy with a super fast, built Dodge Dart, and just as he was about to say how fast ‘that’ car was, Tim stood on it, pulled the front tires up, and laid down twin black stripes as they clawed away down the street. Tim told me later that all kind of explicatives came out of the guy’s mouth as he was slammed back in the seat on launch, and that it was obvious he just wasn’t expecting ‘Zombie’ acceleration….Tim said it was great fun.

Near 11:30 pm, the time came for everyone to say goodbye. We thanked Chris and his entourage for making such a great film and for being so engaged with all the EVers who came on this fun night, and he thanked us for the dedication we all had, and of course, for his thrill ride.

Cheryl and I dropped Jay off at the MAX train station, and we were about to make our way back home when Tim flagged us down. Seems the DC-DC had just called it quits and the Zombie’s lights were dimmed down to an 11+ volt level again…hmmm. A quick check revealed a blown 5 amp HV fuse. We decided to not worry about the problem, as the drive home would be a just 12-15 minutes. Blue Meanie was my concern at the moment, with the pack sagging into the 145V range under 35 mph speeds. To my amazement, the pack hung in there fairly well most of the way home. After about 4 miles though (10 miles total), I started to see 130+V readings, then even lower as we continued to pull mild hills. Long story shorter…we made it home, a 12 mile round trip on Optimas with at least 600 cycles on them. Yes, I pulled the pack down HARD into sub 100V levels on the last 1/2 mile, but the pack recovered well and took in a 1.5 hour charge, most of that at 23+ amps! White Zombie’s pack was sitting at 375 volts right after shutting it down, this after 12 miles, and HEAVY repeated 1000 amp acceleration runs. White Zombie too, was recharged before I went to bed.

The next morning, the Zombie’s pack was sitting at 391V (perfect), and Blue Meanie’s pack seemed to enjoy it’s flogging, as instead of sitting at 158V static (new, it used to sit at 169V) in the winter of its life, it was now at 164V. Subsequent driving these past days has Blue Meanie feeling way peppier and the pack acting like it did a few years ago. No reversed cells and far less voltage sag. Guess those old Optimas can be woken back up.

What a fun night! Thanks again to everyone that made this come together, with special thanks to Brad Hippert who was instrumental in getting my car included as part of the show festivities. Of course, a big thank you to Chris Paine for his commitment to not letting this story get buried by GM and for having the courage to stick with it for three long years in the making.

See Ya…

Fun at the Movies…Chris Paine meets White Zombie!

July 14th, 2006

Hello to All, I had written:

…a few photos from last night’s fun with Chris Paine are up at the Plasma Boy web page. Look for a detailed post later tonight….

Then this from Jim Husted:

I’m so pleased that you got to pull it off last night…I’m not going to ruin the plot for EVeryone and I can’t wait to read the full post.

OK, here’s ‘the rest of the story’……As is typical, this all started bad, very bad. In Portland, Oregon, once we get past July 4th or so, you can count on Summer weather, we’re talking little to no rain and 85-95 degree temps the norm through August. So, anyone wanna guess where I’m going with this? Yup, that damn anti-EV vortex is still after me! I’m not kidding. After 20+ days of sun and warm weather, and with Chris and his crew arriving in town for the big film debut (and a scheduled Zombie ride), a weird July cold front was forecast for mid-week, most likely Wednesday. Geesh! In fact, you just couldn’t get a more deliberate conspiracy from the weather man, with his 7 day forecast showing 85-90 degrees Monday and Tuesday, then plummeting temps and rain ‘only’ on Wednesday, then Thursday and Friday rebounding into the 80s with Saturday and Sunday heading into the 90s again. It seems at every possibility for an EVent this year, weird weather has done it’s best to kill it!

Yesterday morning as I awoke early to start my forklift wrenching day, the smell of fresh wet air wafted through the bedroom window. Right on queue, on the exact day that of the movie debut, the rare for July cold front has rolled in off the Pacific and it’s raining! All day long, it rained. I’m in the back of my service truck doing this and that, and all I can hear is the sound of rain beating down on the aluminum roof…damn! To make matters worse, my planned ‘easy’ day (so I could get off work early at 3:00) is anything but easy and is rapidly going south on me, with one customer freaking out because five, count ‘em, five lift trucks are down all at the same time and I’ve got to get them back on line before I can go home. I call for backup to get an extra tech to help out, but it seems all the techs were slammed on this day…nice! I’m building here, so bear with me……

By noon, it’s still raining, and as I get something repaired and back in service, operators keep stopping by on forklifts carrying more dead pallet jacks over to me. By two, it’s raining even harder and the skies are getting darker. By three, it’s still raining. Work continued to get more insane and each time I got caught up, another repair would show up. The grand total of dead lift trucks came to eight. At near 4:00 however, the rain stopped, the clouds began to go away, and patches of blue showed up as the roads began to dry. Man, was I going to get a break?

I arrived at my house and hour and a half later than planned at 4:30. My wife’s work day had also went crazy and though she had planned to meet me at the house at around 3:30, she didn’t get home until after 4:00. The plan was, that she and I would take Blue Meanie, and Tim would drive White Zombie. The rain thing had just tweaked with me all day, work had gone to hell in a hand basket, and I had cars waiting at home to prep for a show that I really needed a couple of hours for. Now it was getting late and there was little time left to get the cars spiffed up. I had also wanted to take both out for a 4-5 mile ‘wake-up run’ with subsequent recharges to get their juices flowing. Blue Meanie in particular, with its 6+ year old Optimas, would never make a 12 mile round trip to the show and back unless I exercised the old pack before hand. Yeah, things had certainly not gone as I had hoped for. I was tired and dirty with a combination of sweat and hydraulic fluid, I stunk…I was stressed out over everything. Nothing like a shower though, to wash away problems, and by 5-ish I emerged a refreshed Plasma Boy. Tim too, had one of those days but in perfect timing fashion, he was at my door as I was ready to go out it.

We had wanted to be at the theater by 5:30 or so to get both of my EVs in the lineup near the theater entrance with other EVs from the OEVA group, and, we wanted meet up with Chris before show time. Instead, we hadn’t left my house, it was already after 5:00, and nothing had been done yet. My wife isn’t a real happy camper when things go this way. All three of us were hungry, too. I’m still building here……

Blue Meanie gets put on charge to top its pack off…White Zombie, too. At full charge (445V), Zombie’s charger is shut down and the pack rests at 404V right after. The Chris Brune DC-DC is put on line as the 12V system jumps to 14.4V and the packs settles in at 391 volts.

Time for Tim to take the car out for a spin. He goes up the shop driveway and is almost to the road, when the car suddenly looses power and coasts to a stop. WHAT???? Nooo-oooh, not now! A second press-down on the throttle allows the car to make it onto the street, then it dies again. This is definitely bad timing! What’s up with this? We got the car back into the shop, hooked up the Mac, and pulled all these Zilla codes: 1124 (Main contactor stuck on), 1141 (main contactor high resistance), 1221 (Major Overspeed Either Motor Beyond red line by X), 1224 (SLI Battery too low and caused shutdown of controller), 1231 (Propulsion pack open, no contactor drop, and controller is not responding). Geez, what the heck?

So now, it’s 5:30, we’re still in the driveway working on a broken car that’s expected to be at the show as one of the attractions, Blue Meanie ‘really’ needs to be taken out for pack warm-up (or we’ll never make the round trip), and we’re starving. Cheryl comes out with ice cream treats and though she knows things aren’t going well, she says nothing as she hands them to us. This is ‘not’ what I needed after the day I’d had! Tim and I tried to figure out the codes. I hadn’t cleared them since I had raced a few weekends ago, so the older 1224 code made sense…that was when I was driving home pre DC-DC and the 12V battery had lost its will (7-6-06 Electrics Wow the PIR Crowd Friday Night!). So did the 1141, because the contactor had dropped out due to the low 12V problem on that night. The 1231 code happens often, as both Tim and I occasionally forget to insert the interior emergency disconnect handle before atempting to boot up the Zilla. That left us with the freshly imprinted codes 1124 and 1221. Tim was all over it, and within a few minutes, had discovered the rpm sensor’s input lead to the Hairball had come loose…no input from that sensor while flag ‘a’ is on, and you’ll get that 1221 code! The 1124 then made sense, because when the car died due to the tach drive thing, the contactor did not drop out, thus the Zilla said the contactor was ‘stuck on’ because it was still on when the controller had shut itself down.

After reinserting the sensor’s wire at the Hairball and cinching it up with a small screw driver, all was well and the Zombie was ready to roll. Time now, nearly 5:45 pm. Tim takes the car out for the drive, while I take Blue Meanie for a short 1/2 mile cruise through the neighborhood, then return and put it back on charge. That would be all the time I had to freshen up the Meanie’s pack. Tim got back, the car was charged up again, and after quick wipe-downs and vacuum jobs, we were finally ready to leave for the show…it’s now 6:10 pm.

We drove conservatively to the theater, about 6 miles from the Wayland home. Blue Meanie’s tired old 156V pack of Optimas hung in there fairly well, but make no mistake, the days of seeing 165 volts while cruising at 40 mph are gone, replaced these days with 149-152 volts and lots of sag under any type of acceleration. At the theater, as I had assumed, there were no charging outlets to help the Meanie’s pack out. White Zombie’s pack laughed at the drive and still registered 185 volts on the Emeter!

The presentation of EVs was great. Going from memory, there was Gary Graunke’s silver AC powered Insight, Ralph Merwin’s super clean teal Geo Prism EV, a white electric Chevy S10 pickup, Myles Twete’s show stopper dark navy 1921 Milburn EV, Blue Meanie and White Zombie, and a couple other EVs I can’t clearly recall (sorry to those I’ve forgotten). There were lots of people gathering to see the electric cars, lots of video cameras, lots of digital cameras, lots of excitement! As I’m doing my typical show and tell of Blue Meanie (as always, the remote controlled motorized rear battery tray was a big hit), Tim is working a group of folks curious about White Zombie. I had talked with quite few people, but there was this one guy who was very intrigued with the under-hood area of Blue Meanie, and so we chatted for perhaps 10 minutes before he said to me, “Oh, by the way, I’m Chris” (as he gives me a firm hand shake). I was pretty embarrassed that I had not recognized him. We migrated over to White Zombie, where his face erupted into a very big EV grin as he took in its ‘racing attitude’. I told him Rod Wilde had asked me to present him with a pair of rubber shorts to prepare him for his Zombie ride, but Chris’ wit was readily apparent when he instantly quipped back, “Oh that’s OK, I’ve already got them on…wear them all the time.” I knew I’d like this guy! We decided to wait until after the show for his ride experience.

At a little before 7:00 the line formed to go into the theater, so show and tell was over and the real show was about to begin. To be continued…

See Ya….

RIP, Red Beastie

June 25th, 2006

The Red Beastie has met it’s end……

What a horrid thing to read when I’m away from home and excited to catch my email via Wi Fi somewhere in Alaska! As I download and begin to open my EVDL fix of the day looking for uplifting EV stuff, I instead read that Dick Finley’s and my creation, Red Beastie, has been destroyed…ARGHHH! And the way it happened? Incredible!

Of course, my condolences go out to my friend Tony for the loss of more than one EV, his home, and all its damaged goods. Glad to hear he and his mom were away at the time and unharmed.

And so ends the life of the electric pickup that could :-( Today, with NiMH and LiIon making longer distance range possible in our electric conversions, a 120 mile-per-charge electric conversion doesn’t seem all that significant, but back in ‘97, Red Beastie created quite a buzz when it made it from Portland, OR to Seattle, WA and back, 440 total miles mostly at 60-65 mph speeds over varying terrain, with just four recharges during the trip! Back then, it took close to 2500 lbs. of lead, forty T-105 Trojan 6V wet cells to do the deed.

Somewhere floating out there in cyberspace, there’s my EVDL post all about that incredibly fun trip, with guest appearances from Father Time, Marko Mongillo, and Madman Rudman. Twin tow-behind gencarts converged along the I-5 freeway corridor to provide on-road charging power, one brought south towards Portland by the deadly duo, and one towed behind the Beastie on the first leg Marko and I took on our way towards Seattle. Tied together with multiple tangled cords and connectors, they provided 120 amp roadside recharges. My gencart was tame compared to Madman’s. Mine was powered by a chugging twin cylinder air-cooled Onan who’s spinning alternator gave just 120 vac output and fed a variac ‘Wayland-made’ charger. Madman’s cart consisted of a high speed aircraft alternator spun by a stressed-out liquid-cooled Geo Metro 3 banger with a bad muffler. The alternator was hooked into 3 or 4 assorted sci fi project type rectifying devices and outputted 100+ amps! The mid-point recharge extravaganza happened at radical EVer Pat Sweeney’s place, where his ‘Ugly Box’ 240 vac powered capacitor chargers teamed up with our gencarts to pump a stout 190 continuous amps amps into the massive 2500 lb. thirsty Beastie pack. I’m convinced this charging frenzy altered Rudman’s brain and was the genesis of today’s terrific Manzanita Micro PFC Charger line. Man oh man, how we could have used a pair of PFC50s (or even better, a pair of my PFC50X) !!

Today, a 500 lb. stack of admittedly expensive LiIon batteries, could not only match the range capacity of the Beastie’s 2500 lb. wet cell lead acid pack, they could exceed it. I imagine a LiIon powered Beastie type truck (well, it wouldn’t even qualify as a beast with a mere 500 lbs. of batteries) could do the ~185 mile distance between these two major west coast cities on a single charge without breaking a sweat.

80 mile jaunts into the rugged Columbia River Gorge, extended snow driving with its 3000+ watt electric heater blasting, towing a 16 ft. tandem wheel trailer loaded with the Heavy Metal Garden Tractor and White Zombie 45 miles to race at Woodburn, taking Dick’s widow Shirley and her feisty toy poodle ‘Peppy’ out for an evening to see Christmas lights….Ahhh, the memories. Now, Dick is gone, Shirley is gone, Peppy too, is gone, and full circle, so is the electric pickup that made them so happy. RIP Red Beastie, my old friend :-)

(Don’t get me wrong, I respect Dick Finley’s creation very much).

From Roger Stockton:

In all fairness, I think that Victor’s comment still stands.
The Red Beastie got about 2x the range of a typical conversion, and used
2x the amount of batteries…other aspects of performance suffered as a result: this was a 5000lb
2-person vehicle with reasonably slow acceleration despite a decent
motor and controller combination.

I agree with both of your assessments. The truck was actually even heavier, at exactly 5290 lbs. It’s acceleration was borderline, it was very heavy and felt cumbersome to drive, it slowed down on steep hills, and it took forever to get up to near 90 mph, but amazingly it ‘did’ reach the very high 80s on level ground. On the other hand, it was also capable of towing a 16 ft. tandem wheel trailer loaded with my 2300 car, the 500 lb. Heavy Metal Garden Tractor, and a generator plus tools and stuff, at 55 mph from the east side of Portland south to Woodburn, OR, a 45 mile trip, and it still had about 30% charge left.

Victor, I think you and Dick would have liked each other.

May 1st, 2006

Hello to All,

Alan Smith wrote:

What is the longest range everyone has gotten on their ev? If you’ve gotten
over 60, definitely let me know.

Alan’s request does not state specifics such as vehicle types (size and weight), battery pack chemistry, battery pack weight and or BVWR (battery to vehicle weight ratio), weather conditions, the type of terrain, the average speed, the acceleration loads, the number of passengers (if any), etc., etc. I think any response to this request should include as much info as possible so those perusing the results can know the full story. For me, it’s not too impressive to say one got 60 miles of range, if they drove as if an egg were under their foot and kept speeds at or under 40 mph, for example. On the other hand, if one drove their EV like one normally does in a gas car, that is, accelerate up to speed briskly to stay with traffic flow, run along at 60-70 mph freeway speeds, climb various grades, and participate in stop and go traffic driving situations….then achieve a real 50 miles, now that’s impressive.

Here’s three examples from my own experiences:

(1) Circa 1984….Blue Meanie powered by just eight 6V wet cell lead acid golf car batteries with a primitive 3 step controller ( 24V w/resistor - 24V straight - 48V straight) and weighing about 1800 lbs. with batteries, managed 54 miles in a closed loop range rally circuit in Seattle against other EVs. That may seem impressive, until you realize that the speed limit was a tepid 35 mph on flat terrain on a warm summer day (best conditions for range using lead acid batteries). On average, there were two passengers on board, and acceleration was sometimes full-on tire spinning launches contrasted to sometimes old man type starts (excludes Dick Finley type old men). The car had a bit about a 30% BVWR. Acceleration was pretty good for a 48V car, especially in the 0-40 mph range, but real life 0-60 was probably 15 seconds. Normal everyday driving yielded about 25 miles range per charge.

(2) Circa 1997….Red Beastie powered by a whopping forty 6V wet cell lead acid golf car batteries with a lower powered controller maxed out at 450 amps (max current from each battery 250 amps) and weighing about 5300 lbs. with batteries, managed 120 miles in mostly 65 mph slow lane freeway driving between Portland, OR and Seattle, WA on varying terrain that included moderate hill climbing, on a warm summer day (best conditions for range using lead acid batteries). There were no passengers on board, and all accelerations up to speed were deliberately careful to extend range. The truck had a 47% BVWR. Acceleration was OK considering its portly 5300 lb. mass and a 120V 450 amp system. Real life 0-60 was probably 16- 18 seconds. Normal everyday driving around town with mixed city and slower 55 mph freeway driving (the speed limit within the city) yielded about 130 miles range per charge.

(3) Circa  2000 or 2001? …….EV Rental car, a GM EV1 powered by about 1100 lbs. of Ovonics NiMH batteries with a high performance AC drive system and weighing about 2900 lbs. with batteries, managed 110 miles in mostly 70-80 mph freeway driving between Escondido, CA and LA, CA on varying terrain that included moderate hill climbing, on a warm summer day (not the best conditions for range using NiMH batteries, as they like to be cooler). There were no passengers on board, and all accelerations up to speed were deliberately brisk for fun factor. The car had about 40% BVWR. Acceleration was stunning considering its range capabilities. Real life 0-60 was in the mid to high 7 second range. Here’s an excerpt from my story ‘Living in the Past, getting Beat by the Future’ (http://www.portev.org/commentary/living_in_the_past.htm):

At almost exactly 110 miles since I left the Saturn dealership, I had pulled off the freeway and was on Century Drive, stopped at a traffic light near EV Rentals. The EV1 had been flying along for about an hour and a half at 70-80 mph speeds, and had never once felt like it was running short on power. I noticed that there was an estimated 36 miles left on the range meter, so when the light went green, I decided to see what was left as I planted my right foot down one last time…..screeeeechhhh….,chirp-chirp…..scrreeechh….damn that traction control! What an EV! After running along at freeway speeds for so long, and after 110 miles, the thing could still fry the tires at will! I reluctantly pulled into the EV Rental lot and finding a Magna-charger, parked my electric friend and slipped the charge paddle into its nose…..29% battery left! And so ended my four day love affair with the Gen II EV1…one terrific electric car.

See Ya……John Wayland

Hello to All,

I was excited to see this request for acceleration specs, until I realized my car has to be excluded :-(
Steve wrote:

I would like to put together a spreadsheet with some real data on acceleration. I am looking for acceleration data in the range of 4 - 40 sec for 0 - 45 MPH with cars / trucks between 1500 lb and 5500 lb.

Steve’s range of  4 - 40 seconds takes my car out of the performance window he’s set, as it accelerates from 0 to 60 mph in less than 4 seconds, so I guess I’ve got to sit this one out.

4-16-06 Re: Baby Blue Rides Again…cross country in an EV!

May 1st, 2006

Hello to All,

I had written:

>I had also made it possible for Marko’s Fiat to be equipped with the same prototype group 31s, in fact, these two vehicles were the only >EVs on the street with these hard-to-get batteries.”

I heard from Rod who was quick to point out the following details:

>Actually we ran Group 31 Optimas in the British Land Rover with the large and very prominent “P”s on them at Moab. There were >pictures of the batteries in two major magazines, “Four Wheeler” and LRM (Land Rover Magazine) from England.

I stand corrected…sort of :-) If I recall correctly, Rod got his group 31 YTs  several months after I did, so at the time that Baby Blue and Fiamp were running on them, we were indeed ‘the only EVs using them’. If you go to the photo at the following link, you can see that the two center mounted group 31 YT’s shown in Rod’s EV have the retail production lot labels on them, something that took a couple of months for Optima to get around to doing after the initial prototype offer to me.

http://www.evparts.com/about/images/roverFaceOff/H18.jpg

I’m certain Rod will re-correct me if I’m wrong, but I’m pretty sure by the time Rod figured out what I was up to, Optima had run out of enough prototype batteries to fill his request for a full set of them, hence the two later production batteries mixed in with the prototype models.

Ah, the good ‘ol days back when Rod and I were EV rivals…now, it’s almost boring being good friends :-)

4-16-06 Baby Blue Rides Again…cross country in an EV!

May 1st, 2006

Hello to All,

I’ve always loved the 60’s thru early 70’s Datsun minitrucks, the original models that started the minitruck revolution that was the big thing for the 70’s period. Sadly, today there are no more true minitrucks as all have morphed into portly ‘midsize’ pickups. Anyway, some may remember a fun EV I put together back in the late 90’s, a ‘68 Datsun minitruck I called ‘Baby Blue’. It was featured in a documentary about EVs called ‘Where the Rubber Meets the Road’, where I had to convert it from a gasser to electric in one day, on camera. Of course, after that exhaustive 14 hour build, I improved the design. The end product was a 192V, 1200 amp road terror that was super fun to drive. The drive train consisted of an ADC 9 inch motor (properly timed), a Z car 5 speed tranny, racing clutch, the first T-Rex high voltage controller, thick 4/0 cabling, and 16 of the first prototypes of the experimental group 31 Optima YTs. I had also made it possible for Marko’s Fiat to be equipped with the same prototype group 31s, in fact, these two vehicles were the only EVs on the street with these hard-to-get batteries. I had placed the batteries in a custom metal enclosure mounted forward in the bed, leaving about 2/3 of open bed space. The plan was to at a later date, do a tilt bed with the batteries all mounted properly between the frame rails, out of sight and down lower for a better CG. It was a fun little truck that one late night on the freeway, handily smoked a 5 ohh Mustang at 80+ mph to 100 or so. I enjoyed the truck for a couple of years, then reluctantly sold it to me friend John Tuss. The truck is still available for viewing at the EV Photo Album, and though he no longer owns it, is still listed as John Tuss’ truck:

http://www.austinev.org/evalbum/039.html

Fast forward….several months ago, after 4+ years of simply driving this tough little EV as his daily machine, John sold the truck to friend Marko Mongillo of Fiamp fame (Marko’s Fiat 600 sedan also listed at the EV Photo Album). John’s a very nice guy but is not totally into maintaining an EV. The little truck had problems under his care and when two batteries failed (blew up from cell reversal)…he simply dropped it to a 168V truck and kept on driving. John drove the pickup way under its capabilities performance wise, driving as if he had an egg under his foot at all times (his normal mode of driving anything), so he noticed little difference at the reduced pack voltage. The pack never received regulators and pretty much was never equalized in any way. He simply charged it and drove it, day by day, until its range fell lower and lower.

Marko, with a little help from yours truly, has other plans now that he’s the new owner. I handed him 276V worth of brand new Exide Orbitals for the project. The past month or so we’ve been re-converting this nice little truck. Marko out-did his metalworking capabilities and made awesome stainless steel between-the-frame-rail battery boxes that somehow, hold all 23 batteries beneath the bed where they are out of sight. The truck looks like a stock, lowered minitruck with a fully functional bed again….nice! I’ve done all the high current wiring. Jim Husted just put some love on Marko’s motor:

Being that the High Voltage Nationals are only a month away….Thursday consisted of tearing into multiple motors and a lot of prep work…Added was a need to get Marko his motor as he also intends to bring out to Joliet this May.

Ah Jim, you’re letting the cat out of the bag! Oh well, time to let everyone know what we’re up to :-)

I had just returned from central Oregon earlier this week, and as Jim posted, met up with Father Time and Jim on my way through Redmond back to Portland over yummy Chinese food. This past weekend as we had all planned, Father Time came back through town with Marko’s motor in tow. Madman Rudman too, was passing through on his way to Newberg, OR to have Easter with his folks. On a previous trip to Jim’s motor shop, I had picked up the Husetedized front motor from Gone Postal and brought it back to my place, as a service to Rod Wilde. You see, we Pacific Northwest EVers tend to help each other out every chance we get. Why pay hundreds of dollars in shipping costs sending 150+ lbs. of motor the 450 miles or so back and forth between Port Townsend, WA to Redmond, OR, when you can piggy back the thing with your EV buddies? Why should Marko pay to ship a heavy motor from Portland to Redmond and back (300 miles), when John the forklift guy goes back and forth that way all the time? As the commercial says ‘It’s the network’. The circle was complete for Rod’s motor, when Rudman was passing through Portland for the holiday with his family, a guy who lives in Kingston across the woods from Rod’s hometown of Port Townsend. As a sidebar…I could have done an even sweeter motor hand-off, as Tim ‘Electric Monkey’ Brehm left on Friday for a weekend with his mom up in Port Townsend! He wanted to hook up with Crazy Rod Wilde while he was up there, and I could have simply handed Rod’s motor to him and he could have delivered it in person. Oh well, Friday was a hectic forklift wrenching day for me, and quite frankly, I forgot all about asking Tim to take Rod’s motor up there, but with Rudman passing through right on schedule, it wasn’t a big deal.

So here we all were, meeting up at Summit Sheet Metal…Father Time, Madman Rudman, Plasma Boy, and Marko Mongillo.
More from Jim:

I’d really like to stress here that there are some folks out west that are really pushing to ready their EV’s for the May Illinois race and for any of you who might be teetering on the fence to make the effort and attend.  Wayland I know has never been that far east with WZ, and I know EVeryone here is pumped about the Event!
Here’s the deal. Marko is planning a major cross-country trip in Baby Blue. The plan is to have the pickup all finished in time for a car show Tim, he, and I are part of at Mt. Hood Community College on May 5th. For the trip eastward, we’ll place my 10 kw generator in the bed of Baby Blue, along with a PFC 50 charger… a series hybrid for level ground cruising, and relying on stout battery power for climbing the Rockies. With all the recent talk here on EVDL about generators and all, this is a pretty timely project, don’t you think?

From David Roden:

When you add a genset, you have a series hybrid.  The energy conversions involved make it a real challenge to attain high fuel efficiency using this scheme.  It’s not impossible, but a garden variety consumer genset - intended to supply backup power for a few hours during a grid failure - is probably not going to get anywhere close…

Good points, David. We’d certainly like to have a beefier unit, say a 15 kw model, but we have to use what we have available, so we’re cutting it thin with the 10 kw unit I have. To reduce rolling resistance and minimize cruise current needed, we’re going through the entire truck’s rolling gear and have already found thick, sticky grease caked in the rear axle instead of slippery thin gear oil…yikes! The rear axle is getting a thorough cleaning, all new bearings, and thin but effective gear oil. The front hubs and bearings are also getting the work-over with new bearings and all. The front end will be aligned. Finally, thinner high pressure (lower rolling resistance) truck radials similar to the kind Dick Finley and I used on Red Beastie, will replace the low profile, fat street rod tires that don’t roll so well right now. When done, I expect the 276V truck will use about 35 amps (with the 250 lb. generator in back) to cruise at 60 mph or so.

To plan for the worse, Rudman is allowing us to bring his T-Rex as a drop-in backup controller, and I’ll have my spank’n new PFC50X, my experimental 75+ amp charger the Madman and Smalley have been tweaking for me, as a backup to the PFC50 we’ll be using. It should be quite an eventful trek for Marko and his tough Datsun pickup. It will be fun to see how well the truck can pull the steep mountain grades we’ll encounter.

Once we’re at our destination, the exciting electric races in Joliet, Il, while Tim Brehm handles driving White Zombie, I’ll have fun running Marko’s Baby Blue down the track. No, we don’t expect it to set any new records, but having yet another EV to actually race on the track will add to the excitement of the races.

I’ll be posting pictures of the reconversion process to the Plasma Boy website soon.

Hello to All,

Doesn’t the CVT version get lower gas mileage than the standard?

If so, why would you want to use something that lowers your fuel efficiency?

Peter, I’m disappointed, as it appears you must have hit the ‘delete’ key and not read my many posts about this topic over the past couple of years :-(   The CVT has nothing to do with the drop in mileage of the Insight equipped with it.

To recap….At the time Honda and Toyota were introducing the hybrids to the US market, they were in very stiff competition with each other over the new idea of mass marketed hybrids:

(1) Honda caught Toyota with their pants down, big time (even Toyota admits this) when they brought the Insight to the US market a full year ahead of the Prius (even though Prius was marketed elsewhere at the time). Only available as a 5 speed manual at first, the Insight achieved a ULEV status while also getting a staggering 70 mpg EPA rating! The 5 speed Insight uses lots of tricks to achieve super high, previously un-heard of mpg levels including its all aluminum body, super aero shape, its lowered stance, and of course, the whole hybrid-electric assist thing, but it also employs a special lean burn ultra light weight (124 lbs.) 3 banger engine that helps it achieve this mpg (my personal 5 speed Insight logs 90+ mpg easily at 62 mph constant speed and gets in the 80 mpg range without any special effort). Using lean burn though, makes it hard to control NOx emissions, thus the ULEV instead of SULEV rating.

(2) To trump Honda, when Toyota finally got around to introducing the US to the Prius, though its mileage was nowhere close to the two seater all aluminum Insight, it did seat four and was still able to get in the 55-60 mpg range while boasting a cleaner SULEV rating. Though actually transmission-less, the Prius’ automatic nature of its drive train (no shifting required) made it unpopular to those who prefer to shift, but very popular for those who prefer automatic trannys.

(3) To fight back, Honda introduced the CVT option for the Insight (and the Hybrid Civic). To match the Prius’ automatic nature, Honda also had it now with the CVT, and to match the SULEV rating, Honda dropped the lean burn capability on only the CVT model Insight. They ended up with the SULEV rating they wanted, but the car’s stellar 70 mpg EPA rating fell to 56 mpg. Many who don’t know this stuff, explain away the drop in mileage as being the fault of the CVT. In reality, the CVT Honda uses is as efficient (perhaps even more efficient) as the 5 speed…it’s the lack of lean burn mode that made the mileage plummet to the level of the Prius.

There are things one can do to keep their 5 speed Insight to keep it from shifting into its lean burn mode while driving, and when you do so, the 5 speed Insight gets pretty much identical mileage to its brother the CVT Insight. In terms of acceleration power, the CVT Insight is a dead match to the 5 speed Insight, so kudos to the efficiency thing for the CVT….it doesn’t rob the car of acceleration power at all.

For a time, I owned two Insights at the same time, my silver 2000 5 speed and a red 2001 CVT:

(1)  In my 5 speed, as you get up to cruising speed and slightly let off the gas to level your speed off, there’s a cool feeling you get as you watch the informative dash display and see the instantaneous mpg readout flutter at around 65-70 mpg, then suddenly it pops up to 90-110 mpg as you also feel a bit of a floating-like push of the car as its high tech 3 banger makes the hyper mileage jump into lean burn…very cool, very entertaining, and something all of us talk about that are fortunate enough to own one of these amazing machines. Then as road terrain goes up and down slightly, instead of the mpg going up and down, you see the dash indicator for the electric motor assist coming and going as it fills in the voids where, because of the lean burn’s lack of torque, the engine needs a little help…again, very cool and fun.

(2) In my CVT Insight, as you got up to cruising speed and slightly let off the gas to level your speed off, that cool feeling I get with my lean burn car is gone, and the instantaneous mpg readout just continues to flutter at around 65-70 mpg, never popping up to 90-110 mpg level, and that cool floating-like push of the car at the hyper mileage jump into lean burn never happens :-(   As road terrain goes up and down slightly, you still see the dash indicator for the electric motor assist coming and going to help out, but not nearly as often because the 3 banger is in a more normal fuel-air ratio so torque is improved slightly, and, the CVT does an excellent job of keeping the ICE in its sweet spot. As a side bar, I was never, ever able to even get close to the same gas mileage as my 5 speed Insight, but I was able to hit 72 mpg on one 200 mile trip. On that same trip where my wife was following me in the 5 speed car, she got 86 mpg.

You don’t have to follow the Honda Hybrid list, all you have to do is stay current with regular car magazines. Pretty much all of them have featured the latest improvements and changes of the new hybrids. The big news is that Honda’s latest version of the Civic Hybrid can run a few miles on electric power only, just like the Prius does. Compared to Toyota’s complex trio of an electric motor-generator, a generator, and an ICE all coupled together via sun-planetary gears, Honda gets it done in a far simpler, more elegant way with their IMA system (integrated motor assist) with just the one motor-generator (less than 3 inches thick) sandwiched between the tranny and the flywheel and sharing the ICE crankshaft…no extra gears, no convoluted electrical-mechanical swapping of power and loads.

Damon, you disappoint me :-(   You need to get up to speed, dude! The 2006 Honda hybrids will in fact, run on battery power alone. They do it, just the way I predicted they would 5 years ago. They close the valves in the engine, cut off the injectors, and let the stuff all spin along with the electric motor. Having all the valves closed amounts to the same thing as having them all open, in that there is very little drag against the electric motor, probably not any more drag than the Prius’ drag caused by the planetary arrangement they use.

Hello to All,

Just wanted to remind everyone who receives the Discovery channel, that our own Rich Rudman and Shawn Lawless will be on TV tonight on the Monster Garage show. Should be a hoot! My local TV listing has it on at 8:00 pm west coast time.

I met the guy who does the voice over for the show while we had White Zombie on display at the Rod & Custom show this past February. He was excited to tell me that he was scheduled to do his part for the show the following Monday. He was pretty pumped up over doing this episode, and told me seeing White Zombie and the drag racing videos of it jerking the tires off the ground and blowing off muscle cars took him by surprise. I think we helped prime the pump for him to be really excited about the electric Chevy Rich and Shawn helped build.

Hello Osmo and All,

Osmo S. wrote:

DC vs AC … what about sepex, PM, BLDC and whatnot. Do they all belong in the category of DC? Or does DC stand for a brushed series wound motor only. If so, why aren´t the others hardly ever discussed in this group?

When talking EV sized brushed wound field type motors, it is generally assumed that they are series-wound types. They don’t have to be, they could also be shunt wound, sepex, or PM types.

BLDC (brushless DC) motors are as complicated to control as AC motors are, in that they require an inverter or they cannot run. A BLDC is really an AC motor who’s inverter is generally built into the motor case. It’s an AC motor that has no brushes but you feed it raw DC power…hence brushless DC.  Once the power gets into the motor it’s routed through an inverter that converts it to three phase AC. Most are synchronous types where the rotor is a permanent magnet, so they have different characteristics compared to induction type AC motors. Today’s BLDC motors have changed and many now have three feed wires that get power from an external inverter. To me, I call this an AC motor, but the companies that build these still insist on calling them BLDC….go figure! In a nutshell, a BLDC motor is essentially an AC motor, thus an EV BLDC system with EV levels of power have the same high cost as the induction type AC systems. Unique Mobility makes EV sized BLDC systems, but I think they’re priced in the $20k range. I rode in a Humvee powered by four Unique Mobility 100 hp BLDC motors, it was incredible! At $20k, you can see why we don’t talk much about them or use them often.

On a much, much smaller scale, I do own an EV that’s powered by a BLDC motor, it’s my very early model Curie board scooter. When other scooters of the period (pre-2000) were still stuck in 12V land, had a PM motor that ran at 57% efficiency with a binary controller (an on-off switch) and used a friction drive or belt drive, this one ran at 24V, had a chain drive, and employed Curie’s own design BLDC motor at about 95% efficiency with variable throttle control due to the built-in inverter-controller on the backside of the motor. Scooters back then were rated at 15 miles range per charge, but in reality got about 6-7 miles before needing a recharge. My Curie was rated at 12 miles per charge and easily did it. It was also way faster on top end, and off throttle it coasts forever so you only need to blip the throttle once in a while to cruise along. After a few mile son a regular PM 12V scooter, the motor got very hot to the touch, but the Curie BLDC feels barely warm. Today, I have five board type scooters, but my favorite is still my original Curie with its BLDC motor. I just bought a new 36V Curie that has a real disc brake, and full suspension and all, but the disappointing factor is its PM brushed motor. It even has the warning ‘Caution, motor gets hot!’ I assumed when I ordered this scooter, it would be an upgraded version of my trusty Curie …not!

As to sepex and PM, yes, these are considered to be good ‘ol DC motors. There aren’t many large PM motors readily available in road going EV sizes, and a PM of this size would not have the ultimate low end torque of a series wound type, thus, they are not popular. Sepex are also, not readily available and they require more complicated controllers. Randy Holmquist of Canadian EV has rewound Kostovs that are turned into sepex types. Jim Husted could also turn any motor into a sepex type. Sepex have really taken over in the forklift industry and with gear ratios changed to improve low end torque making them on par with series wound types, they work very well, with the added plus of very controllable regen.

Hope this helps…

The biggest thing that bugs me about most DC systems is the huge
amount of current the battery’s have to supply just to leave a stop

Huge amount of current just to leave a stop light? Where do you get that from? The average 144V-192V DC systems do not have to use ‘huge currents’ just to leave a stop light. My 156V car takes just 50-100 amps to leave a stop light at speeds matching traffic flow. In order to match the not-too-exciting 100 kw AC system’s ‘maximum’ leave the stop light capability, it still only takes about 300 hundred amps through a transmission, something most everyone uses with these DC systems. The huge currents (really not all that huge) only come into play when one wishes to demonstrate the 144V-192V DC system’s 6-7 second 0-60 acceleration capabilities, such as when wanting to dust off one of those lower powered 100 kw AC systems :-)   Using quality AGM batteries (wimpy gel cells need not apply) like Optimas, Hawkers, or Orbitals, the high currents are not a problem at all, in fact, these tough batteries seem to thrive under such treatment…witness my Optimas that finally died after 6.5 years of nearly constant high current acceleration blasts! Witness the Exide Orbitals that never, ever failed under repeated 1/4 mile drag strip runs. Witness the Hawkers in White Zombie that never, ever failed throughout the 2005 racing season.

With most AC systems you
need higher voltage to get the watts up, but the battery pull 500 amps
max on the high powered systems I am familiar with. Many limit to 200
amps. That makes battery and interconnect choices easier.

You can get the exact same results in a high voltage DC system, so I find this comparison you’ve made interesting, because it’s an apples to oranges thing. High voltage AC to low voltage DC? If you want the low current battery thing you ’seem’ to be saying is the AC’s advantage, then simply run a high voltage DC system….you know, apples to apples.

In White Zombie, at 348V, it only takes about 50 amps from the battery pack to accelerate as a normal car does in average street driving, and it takes a whopping 20-25 amps to cruise at 55-60 mph. Driving as if I were in a 96V Rabbit or a Solectria Geo Metro, the car uses about 40 amps from the batteries to accelerate up to speed. The difference of course, is that my high power DC setup gives me the option of pulling 1000 amps from the high voltage pack (if I so deem it necessary and have it programmed the max battery amps this way) for extreme acceleration, something the 100 kw AC system you are comparing to, cannot remotely achieve.

The beauty of the 144V-192V DC systems is that you can afford these, they give superior acceleration when compared to the 100 kw AC systems that are double the cost, and using quality AGM style batteries, in particular the three brands I’ve mentioned that have a proven track record (pun intended), there really are no cabling or connector issues.

The only AC failure I’ve ever known was when the 12v accessory battery
got hooked up backwards ;)

The AC powered S-10 (Hughes Dolphin 50 kw) I had in my possession years ago failed, big time. The repair would have been so expensive that the truck was salvaged by the owners instead of being repaired. A DC truck would have been back on the road at minimal cost. The AC systems Victor (Metric Mind) sells have a very good reliability record.

It seems odd that you would favor an AC system at twice the cost, twice…because it ‘bugs you’ to pull high amps from a battery pack, when a DC system at the same voltage does the same thing while also giving you far more available power at far less dollars.

Hello to All,

Michaela Merz wrote:

Hmm .. I think we all agree that a blown DC controller can cause some
problems. What about doing something about it? …a secondary system monitoring motor voltage and shut the system down if something seems to be wrong?….a way (for an electronic circuit) to know the difference
between a PCM signal and a constant DC on the motor? It could trigger the
mains before the driver knows that the controller went south….ways to detect this kind of dangerous conditions and to prevent a ‘runaway’ car :)

It’s already been done…it’s called a Zilla with Hairball.

All Zillas are controlled by the Hairball interface. First and foremost, Cafe Electric builds the most reliable DC power stage ever, period! His power stages simply don’t blow, that in itself is amazing, but when you consider the very high up-to 2000 amp currents (even the ’small’ one kicks out 1000 amps!) and the industry leading up-to-348 volts and they still don’t blow, is incredible! Lesser controllers have a hard enough time managing 500 amps and 156 volts :-) The Zilla controllers power the worlds quickest electric drag cars, and don’t blow even under these extremes.

I’ve got credibility here and have ‘been there, done that’ in regards to blowing things up. The 5300 lb. Red Beastie electric Toyota truck Dick Finley and I put together was the ultimate test bed for seeing how robust controllers were. With a 2500 lb. battery pack capable of running the truck for hours on end at high average currents and at very high currents during hill climbing events, it ate 6, count ‘em, 6 controllers! Having been involved in too many conversions to list over my 26 years of EVing, I’ve blown up more controllers than most, believe me. I think my ‘We blow things up, so you don’t have to’ mantra was part of Otmar’s inspiration to make his Zilla line of controllers bullet proof (or would that be plasma proof?). The original Godzilla controller used to set world records in White Zombie never failed, ever. It lived through everything I threw at it, including the melt-down of the armature in the 11 inch Kostov under full power. It’s still in perfect condition and awaits its new owner (I’ll let him tell everyone when he’s ready).

In the very unlikely event of a Zilla power stage failure, the Hairball instantly drops out the contactors, and in many circumstances, it will sense a problem ‘before’ the power stage can blow and not allow any contactors to pull in.  Old fashioned Curtis controllers don’t have this feature, nor do many other old tech designs. I was at Oat’s side when he was first working on the Hairball interface, and even gave him my input on his ideas for its features and multitude of protection circuits…even threw some of my own ideas at him ;-)   The prototype interface was a mess of tangled wires strewn all over the place as he was first conceiving the idea, looking very much like what the cat coughs up…hence, Hairball.

DC controllers ‘can’ be every bit as safe and automatic in their control systems as any AC system, the Hairball/Zilla combo is proof.

4-8-06 AC vs DC

May 1st, 2006

Hello to All,

I always enjoy the AC vs DC debate. One point very rarely brought up though, is what you get in terms of performance in return for your dollars invested, especially when the price of the AC system hovers in the $8000-$10,000 range. Yes, a  68 kw AC system can be had for about $6000, but that’s on the low side of power for a conversion and is more comparable in power to older tech 120V DC systems. To get up to the power level of today’s common 144V-156V DC systems being used that easily top 100 kw, the AC system will cost you closer to $8000.  For $8000-$10,000, you get an AC system with about 100-130 kw of power. For the same dollars for DC….listen up newbies and pro AC folks,  you get up to 600 kw!!!! I’m talking about raw power that can be easily had with a Zilla Z2K, stout AGM batteries, and either one BIG DC motor or a pair of DC motors.  Now, in real life, due to the fact that batteries sag under high current loads, no one that I know presently has actually gotten their 600 kw of power delivered in their EV, but I do know that 350 kw has been had :-) We’re talking about THREE times the power for the same price…I’ll repeat….THREE times the power for the same price! Not just two times the power, THREE times the power!

From Metric Mind’s web page, specialists on AC systems (good folks to do business with) comes this statement:
>Zilla 2K comes to mind….with a DC motor becomes $6100, just $800 less than a complete AC solution (100 kw).

It goes on to admit that even the Z1K at half the power of the Z2K still has more power than this AC system, but the power level thing is down-played. The problem I have is where the Z2K, a 600 kw system is compared to the 100 kw AC system, where this part is left out…..The Z2K Zilla package delivers SIX times the power for the same price (if a powerful enough battery pack is used) and in practical terms, it delivers THREE times the power!

A nice 100-130 kw AC system ‘can’ match the power delivery of the average gas car, but so can an affordable 100-130 kw DC system.
The big difference in this power range, is that a simple pack of just 13 AGM 12V batteries (156V) and a Zilla Z1K will easily make 130 kw of delivered power. Here’s the approximate cost to do this….$2000 for the Z1K LV model, $1450 for 13 Optimas or Orbitals, and $1600 for a 9 inch DC motor, for a total 130 kw package of $5050. A 100-130 kw AC system will cost you about $7000, but to run it to the power level of around 100 kw, you need a 300V battery pack. That pack will cost twice as much as the 156V pack for the DC system, even if you run smaller AGM batteries so that the overall pack weight is the same (same approx. range) as the 13-battery DC pack. So, for $7000 for the inverter-motor combo and $2800 of batteries you are up to $9800! We’re looking at twice the cost for the same level of performance. When using battery management modules, the cost of these is doubled with the 300+V AC system, too.

Am I dissing AC? Of course not. I love AC. My Insight has it, many of the forklifts I work on have it, and one of my favorite EVs I’ve driven, the EV1 had it. From time to time, I think about converting Blue Meanie to a 130 kw AC system. After all, I already have a really fast DC Datsun 1200, why not have a little regen fun and do the other 1200 as an AC system? The only problem I have is price for what you get in return. With similar weight lead acid battery packs, I’ll pit my DC powered car to ‘any’ AC powered car in terms of range per charge, 0-60 acceleration, top speed, and over-all fun factor. On the other hand, a direct drive AC Blue Meanie with a higher tech battery pack is a fun concept.

From time to time, I get to hang out with Victor (Metric Mind). A few weeks ago, he and I got together at his place. I found myself smiling at his latest AC system with a very compact inverter module and a motor that was, well, more ‘motor-like’ than some of his other square AC motors. It screamed ‘Blue Meanie’ at me. I also nearly tripped over stacks of Ovonic NiMH batteries, the same models that were  used in the EV1 I drove for 140 miles per charge years ago! I was thinking a set of them and that nifty compact AC system would turn Blue Meanie into a 150 mile per charge machine, while still maintaining ‘respectable’ performance. Alas…..it would cost about $10,000 to get these toys.

For now, I’ll be putting a pack of Hawkers into Blue Meanie to get it back to snuff (the 6.5 year old Optimas are finally ready to be recycled). Until I take the AC plunge, I guess I’ll have to settle for 0-60 in six seconds, a 120+ mph top speed, and the ‘city driving only’ range of 25 miles per charge (unless I get some really new model Hawkers I’m not supposed to talk about yet).

Kudos to Victor for helping to make AC systems available to backyard converters. It’s great to have these systems available at more reasonable prices than the $20-$30k systems of the late 90’s!

We don’t recommend less than 96V for a very basic street car, nor do we recommend above 144V on the 9″ motor.

I’ve run Blue Meanie’s ‘properly advance timed’ ADC 9 inch motor at 156V for I think, 10 years now. Not a single motor problem, and the original brushes are at around 75% still. Many others, like John Bryan and his 192V Ghia with its XP super torque’n 8 inch ADC motor, have also not had any problems at all….nor has Bill Dube’s 192V Wabbit…this list could go on and on.
>Your privilege.  But I sell these and have to warranty them.  I want the factory backing >me up.
Shari, perhaps you are unaware, that  ADC left Corbin hanging when their 8 inch motors all started to burn up, due to how they shipped them at neutral timing, then didn’t back their product up. They immediately blamed everyone else, including the controller designers who’s output stages toasted when the motor arced to death. Funny thing (just using your own words, Shari)…when the owners of Corbin Sparrows advanced the timing, magically, all their motor and controller problems vanished. Damon Crocket’s DC Power Systems left the road going EV market over the Corbin fiasco after losing lots of money trying to do the right thing by warranting their Raptor 450 controllers that were burning up due to ADC’s improperly-timed motors that were fire-balling.

I have this funny idea of knowing the manufacturer (ADC) isn’t smart enough to advance the timing to 10-12 degrees so that their motors will run properly for the market they sell them for…EVs.

>I would love to see you tell Gary Dieroff to his face that he isn’t smart enough to build >a motor properly.
Shari, please at least quote me accurately. I said “(ADC) isn’t smart enough to advance the timing to 10-12 degrees” I never said they weren’t smart enough to build a motor properly. They once did ship them properly timed, then, when Gary was less involved in the whole EV motor business, they without warning anyone, began shipping motors timed at neutral without the ability to change timing holes. Actually, I’d love to talk again with Gary. I’ve talked with him face to face before, and had no problems talking straight talk with him. He’d more than likely want my input, as he did back in ‘96 when he was amazed at the power I was extracting from his 9 inch motor back then. We talked for some time track side, about proper motor timing and how the ADC 9 inch had the ability to run at higher voltages when properly timed.  I doubt you ever have similar ‘high performance’ conversations with him over 96V conversions, though :-)

Can you say Corbin Sparrow?

That’s Corbin’s problem, not ADCs.  The Sparrow had problems with several drive systems.
Shari, you need to get your information correct before presenting it as fact. The Corbin Sparrows had drive problems ’specifically’ with every motor controller they used, until motor timing was corrected that stopped arcing. ADC was silent about their culpability in this. I had to personally drill and tap a Sparrow motor for a friend who had one to advance the timing. Guess what? After the mods were done, the car stopped blowing controllers due to arcing caused by ADC’s motors they sold that were shipped at neutral timing! The car also accelerated far better, too.

Add in the fact that most of the Electro Automotive designs feature very heavy conversions with lower than average power, and you are asking the motor to work under even more duress. Most of the Electro Automotive designs use the squealing Curtis controller

Here we go again.  I’ve never heard the Curtis squeal except backing out of a parking space, when it serves nicely as a pedestrian warning.  In forward motion, I accelerate through that low speed squeal too quickly to notice it.
Perhaps your hearing is impaired? Review the EVDL archives of all the complaints from EVers, especially those who were embarrassed at parade events, EV car shows, etc. over comments about the noise their Curtis powered EVs made.

(Yes, even in my pitiful low voltage, low current car, I can accelerate that quickly!)

Prove that,  please. Please show data on the 0-60 of your 96V Rabbit conversion. At the sagged voltage under the 500 amps that squealer makes, you’ve got 40 hp to move 2900 lbs…..yeah, I bet it really hauls! I’d bet you’ve never, ever, drag raced it on a track with real timing devices. I’ll help you out here… My guess, is that it would have a 2.5 second 60 ft., that the 0-60 would take 17-19 seconds, and that top speed on level ground might be a real 85 mph, given several miles to get there.

And as for low performance, I have more often been held back in a 96V Rabbit by slow gas cars than vice verse. I have even passed gas cars going uphill….Sweeping generalizations about “most people” are usually misleading.

And you talk about sweeping, generalized statements? This hardly backs up your talk. Try hard facts, please. Try it like this….

The stock 1981 Rabbit weighs 1775 lbs., has 74 hp, and takes 12.6 l-o-n-g seconds to get to 60 mph. In today’s terms when the average economy car does the 0-60 run in 8-9 seconds (even the squeaky clean running 70+ mpg Honda Insight does it in 10.4 seconds), a 13 second 0-60 time is considered s-l-o-w! Keep in mind, this is for the light weight gas version…I haven’t gotten to your  2880 lb. EV conversion yet.

Now, pull the gas engine out that weighs 220 lbs. and the light weight gas tank and fuel lines and such, and you ‘might remove $250 lbs. of stuff. Now, put in the ADC 9 inch at 143 lbs., the adapter set to mate it to the tranny at ~ 30 lbs., a controller and braketry at 20 lbs., and the brackets and cabling for for all the batteries at around 50 lbs., and you just negated the weight you removed. Now, add in 16, 70 lb. batteries and you’ve added 1120 lbs. to the car. 1775 lbs. + 1120 lbs. gets you 2895 lbs. (100 lbs. more than Shari’s claimed 2880 lbs.) Now, most Rabbits weighed more, as in the 1983 version that weighed 2000 lbs……2895 lbs. + 225 ‘1983′ extra lbs., and the car now weighs 3120 lbs.  Gee Shari, sounds an awful lot like my quote “a 96V Rabbit, a small car that unfortunately weighs in at over 3000 converted lbs.”

Let’s just round the conversion weight to 2900 lbs. and give Shari the nod here. Shari, again, please give the 0-60 time of a 2900 lb. car with 40 hp to move it, compared to a 1775 lb. car with 74 hp that we know does 0-60 in 12.6 seconds, and that is generally regarded by all automotive testers, experts, and drivers to be very slow in terms of acceleration power.

And the poor ADC 9″/Curtis 20×6V Voltsporsche?  90+mph. Yeah, pretty sad and inadequate.

Actually, it is when you consider several things….like how long it takes to ‘finally’ arrive at 90 mph, as in the 0-60 time of probably 16 seconds, and as in how it slows on steep hills struggling with all the extra weight (1400 lbs.  of lead) and only 50 hp to drag it all up said hill.

Rant:
There are a lot of different kinds of people who drive EVs.    This means “most people you hang out with”, which is generally a like-minded group, a subset of the EV universe, not the whole.

Actually, I like to compare EV performance to the gas cars we all want to replace them with, something you seem to nicely avoid when talking about 96V conversions.

If we could refrain from calling other people’s well-loved conversions “dogs”, “slugs”, “underpowered”, and similar slurs and recognize that satisfactory performance is very subjective, then I will continue to refrain (as I have until this moment) from comments about testosterone poisoning and cars as penile prosthetics.

End Rant

Whew….thank god the rant stopped!

Shari, you triggered my post when you used the disrespectful wordage “We have this funny idea that we believe in following manufacture ratings…” in response to Jim Husted’s sincere and knowledgeable comments. Your tone was derogatory at best, and Jim certainly didn’t deserve the treatment.

You need to read what you write before taking a holier than thou stance as in the above comments. To be clear, I only referred to my car I once owned that I very appropriately named ‘Sluggo’. You’re now telling me I can’t name my own cars? I also quite accurately stated “most of the Electro Automotive designs feature very heavy conversions with lower than average power”.  Compared to the stock 1775 lb. Rabbit, a 2900 lb. Rabbit is a ‘heavy conversion’.  Compared to the 2000 lb. 914, your 120V conversion 914 at 3400+ lbs. is indeed, a heavy conversion. Your 96V Rabbits are slow, either compared to stock gas Rabbits (which can run off and hide from your conversion) or other Rabbit conversions with considerably better power to weight ratios. I also stated “a prescription for low performance” in regards to a 3000 lb. car with just 40 hp…no knowledgeable automotive person would call that anything but the honest truth. Apparently, you have a problem with an honest assessment of things like this?

If you want to talk about your conversions as being reliable, affordable, or in being adequate to get from point A to point B, that’s fine with me, and you’ll get no arguement.  Expousing the performace of heavy low voltage, low current conversions as comparable to gas cars though, is not wise, nor is challenging the opinions of expert electric motor folks like Jim Husted. You might just learn a few things from his 25+ years as a DC motor rebuilder.

Please, the slurs only came from you, Shari….”testosterone poisoning and cars as penile prosthetics”. I rest my case.

See Ya…John Wayland

Hello to Steve and All,

Steve wrote:

Books and internet research are one thing, but the experience of this list (plus my experience with 3 EVs) is priceless. I want you to have an idea what I was trying to accomplish, budget, and my performance expectations.  Also, I want to tell you what I am basing my calculations on.  Then, we can have an informed discussion.

I agree with your take about the cumulative knowledge that’s available here on the EVDL, and I like the clarity you’ve laid out.

First, what I am trying to do (design inputs)
1) Small, light weight commuter car.  Note, around here, a commuter car goes 45 - 50 MPH for 10 miles back and forth to work each way.  Why?  Smaller, lighter, etc. means more efficiency, less batteries, less weight to lug around, better handling, easier to fabricate, lower cost to build and maintain.
2) A 20 mile usable range, 365 days a year, rain or shine, hot or cold.  It gets down to the mid 20’s here and as high as the high 90’s.  Of course, for my calculations, the mid 20’s yield the worst case range.  I don’t want to kill the batteries, so I was planning on a 70% DOD max (nominal on the coldest day, 80% DOD absolute worst case on the coldest day if I have to make an extra stop on the way home).

The answer here is pretty simple, and it’s a tried and proven concept when talking about available, affordable lead acid
batteries. To get the range you’ve outlined with the 70% max depth of discharge, you need to follow this formula….when your EV is finished, the battery pack should be 1/3 the total weight of the vehicle. In other words, if the completed car weighs 3000 lbs. with the battery pack, then the pack should be 1000 lbs. To get your Festiva to fit this prescription, it would have to weigh around 1900-2000 lbs. stock,. The added electric motor, brackets, charger, and cables would pretty much equal the weight of the gas engine, exhaust system, gas tank, etc. you remove, so you’re still looking at around 1900-2000 lbs. Now you can clearly see that you need about 1000 lbs. of batteries to get that 1/3 battery weight target.

- 84 V pack - flooded lead acid - 6 V batteries (T125’s)

Perfect. 14 X ~ 75 lbs. = 1050 lbs. of batteries. This pack would be far cheaper than any 1000 lbs. of AGM type lead acid, and if you can keep average cruise currents low, the higher ahr of the flooded batteries will go a long ways towards best range per charge. However, at just 84 volts and a safe max discharge current for these flooded type 6 volters of about 500 amps, you’re never going to get the other goal you’ve outlined here:

I want GOOD ACCELERATION!  Better than the ICE version (which was very
slow).
At least as good as my Toyota Corolla with 1.8 L, 4 cylinder engine.  I’m
not asking for a drag car, but I need to keep up with the hectic traffic
here in
Atlanta.  If it can’t do that, I’m not wasting my time or money.

Pulling the 500 amps max. safe current from your 6V flooded batteries will cause the not-too-stiff 84V (nominal) pack of flooded batteries to sag down to around 65 volts. 65V X 500 amps = 32.5kw, or about 33 hp. Just 33 horsepower to move a 3000 lb. car, should make it pretty obvious this low of a voltage at 500 amps is not by any stretch of one’s imagination, going to give ‘good acceleration’. In fact, even if you doubled the amount to 66 hp, it still would only be ‘OK’ acceleration in a 1.5 ton vehicle. Maybe now, you can see why most everyone else these days, run at least 144V. At 144V and using low-sag AGM types 12V batteries, 1000 lbs. of them would only sag to maybe 125V at 1000 amps to give 125kw, or about 130 hp.

Back to your requirements of low cost though…..you ‘could’ still get by with the inexpensive 84V pack of golf car batteries and get ‘OK’ 0-40 mph acceleration, by spending a bit on the controller and dissing the old tech restrictive SCR controller…read this, get a Z1K Zilla. With this compact controller, you could dial-in 1000 motor amps and still keep the max. battery amps to 500. The controller will be able to boost the motor up to 1000 amps while its voltage goes from 0 - 40 volts as it revs up. After that, the motor amps would fall to keep the max. programmed battery amps at 500. This set up though, would protect the flooded batteries from over-current while still giving your 3000 lb. Festiva very decent low speed traffic type acceleration, probably not as quick as the 1800cc Corolla in the 0-40 sprint, but not too far behind. From 40-60 mph things would definitely be tame, but probably acceptable for your needs. This is beginning to look similar to your ‘option #4′.

To reduce costs in option #4, you could find a used EV motor, I would think for $300-$400 dollars if you looked hard enough and put out enough feelers. You could certainly find a 48V forklift traction motor for a few hundred bucks, and with simple timing adjustments, it would work very well. You could also build a basic charger with a timer shut-off for maybe $200.

My money would be on the 84V pack, the Zilla Z1K controller, a basic charger, and a used forklift or smaller EV motor. You’d end up with an affordable EV that has pretty good off-line acceleration, ‘OK’ 40-50 mph performance, and sluggish 50-65 mph performance. You also end up with an EV with a 30-45 mile range, depending on temperature and other conditions. I agree, keep the clutch.

Just my two cents worth….

4-1-06 Re: Motor options

May 1st, 2006

Hello to All,

From Jim Husted:  At only 84 volts I doubt you can feed a 9er.  Most people are running 2X to 3X the rated voltage of the motor.

Electro Automotive wrote:

Huh?  Maybe most people you know run 2x - 3x the motor’s rated voltage.  Maybe they are drag racers.  Maybe they melt motors.

Yes, guilty as charged as to the drag racer thing. This happens though, at the ‘very’ high voltages and ‘very high’ currents where we are pushing the performance and durability edge. On the other hand, with expert motor help from Jim Husted, so far, melted motors are a thing of the past for now.

We don’t recommend less than 96V for a very basic street car, nor do we recommend above 144V on the 9″ motor.

I’ve run Blue Meanie’s ‘properly advance timed’ ADC 9 inch motor at 156V for I think, 10 years now. Not a single motor problem, and the original brushes are at around 75% still. Many others, like John Bryan and his 192V Ghia with its XP super torque’n 8 inch ADC motor, have also not had any problems at all….nor has Bill Dube’s 192V Wabbit…this list could go on and on.

>We have this funny idea that we believe in following manufacture ratings, thus maintaining warranty.

I  have this funny idea of knowing the manufacturer (ADC) isn’t smart enough to advance the timing to 10-12 degrees so that their motors will run properly for the market they sell them for…EVs. Can you say Corbin Sparrow? I also have this funny idea of running an EV’s motor at higher voltages for far less average current to keep the motor running cooler, the com. and brushes lasting far longer, and for making power on order with what the gas version originally had (or even more).

I would suggest that running these motors at between 96V and 120V is probably way harder on them, than at higher voltages, because to get any semblance of acceptable power at these lower voltages, the average current needs to be way higher than when run at the higher voltage levels, thus more heat and com. damage. Add in the fact that most of the Electro Automotive designs feature very heavy conversions with lower than average power, and you are asking the motor to work under even more duress. Most of the Electro Automotive designs use the squealing Curtis controller only capable of 500 amps. On a 96V Rabbit, a small car that unfortunately weighs in at over 3000 converted lbs., considering 6V wet cell voltage sag under 500 amp draws, there’s only 40 kw of max power, or just 40 delivered hp to move 3000 lbs. of mass….argh! Talk about a prescription for low performance and an overheating motor!

The 108V Ford Escort conversion I used to own that I lovingly named ‘Sluggo’ had a 9 inch GE motor that got so hot I could barely touch it. With its low performance Curtis controller and low performance wet cell pack, this over weight 108V EV had miserable acceleration and hill climbing ability, and a motor that was always very hot due top high average currents at low voltages.

I find it rather amusing to hear Shari arguing motor durability with the likes of Jim Husted, a guy who’s adult life has been immersed in electric motor design and repair, a guy who makes his living working on all models of DC motors for EV use, and the guy who co-designed and built the world’s most powerful, the world’s quickest and fastest, and world record setting 8 inch DC motor!

Hello to All,

Roger Stockton wrote:

I think John’s concern is with adding *any* additional contacts and
wires into the motor loop due to their associated losses.

Correct.

As soon as the motors start spinning, the back EMF is going to make
their effective resistance great enough to make a few milliohms
difference in wiring resistance unimportant.

Yes, but it’s the all-important launch at the strip, where there’s very little back emf at first, that’s the most important area where any high current losses count, big time. I agree, once the car is moving along and the motors are spooled up, there would be very little difference caused by F-R contactors.

Look at it this way; Matt’s car is running the same controller as
John’s, and a pair of 9″ motors, and he is getting *very* respectable
performance (perhaps even better than John’s when you factor in vehicle
weight) even though he does have a reversing contactor in the motor
loop.

Yes, but if he were to rewire the motor(s) circuit more directly and leave all the cables and contacts for forward-reversing out of the loop, he’d probably pick up .2 - .4 seconds! That’s not important for everyday driving for sure, but for 1/4 mile drag racing and chasing after a record, it’s HUGE.

My concern would be that a reversing contactor relies on current flowing
though the NC and NO contacts depending on the direction selected, and
usually NC contacts are rated for less current than the NO set.

Again, correct. Otmar’s 914 has experienced this problem already. Here’s a car that pulls BIG currents all the time, as it’s his rolling Zilla test bed. The NC contacts that rely on spring pressure burn more quickly than do the NO contacts that are closed under more pressure from the magnetics of the coil.

I would
think that wiring the reversing contactor so that it must be energised
for forward “gear” so that the NO contacts carry the heavy race current
would be a good thing to do.

I thought about that as well, but it only adds even more 12V current to be draining all the time, and the default mode is having the car in reverse if the 12V power is interrupted to the forward-reversing set.

For vehicles trying to set world records or for those that already own the record and are chipping away at precious fractions of seconds, every little thing counts. I’ve found that eliminating the high current losses in the motor loop circuit has improved the car’s 60 ft. and 1/8 mile times. Having just one high extra high current contactor for the front motor (that would open the field circuit so that a smaller F-R set could reverse it) with the old dual motor setup, caused an unbalanced wear condition of the brushes and coms between the two motors. Where I got rid of that contactor, the problem went away, and the 1/8 mile times improved.

For vehicles that are mainly for street with setting world records a secondary concern, the reversing contactor sets work fine. If I were to suddenly retire White Zombie from track racing and turn it into a ’street only’ vehicle, I would have no problem installing F-R contactor sets. For now, where we are a mere .151 seconds away from hitting the 11’s, I’ll stick to having just fat 4/0 cables and thick copper bus bars inter-connecting the twin motor sections of the Siamese 8.

3-29-06 Re: Fast Street Car with Twin DC Motors

May 1st, 2006

Hello to Don and All,

I see my buddy Jim has already responded, but I’ll throw my two cents worth in as well.

Don Cameron wrote:

I am **very** interested in this DC siamese motor config of John’s and
Matt’s.

Cool. It’s not everyday where we see an AC guy who’s also interested in DC systems, especially high performance DC systems  :-)   Yes, the extreme power delivery of twin DC motors in a series-parallel and fed with 2000 motor amps is addicting. As Jim pointed out, currently, White Zombie’s Siamese 8 is the only one of its kind. I’m hoping there’ll be more to come, though.

Here is what I undestand so far (from what I have read here, the
archives and off the net):

- single Zilla 2K controller
- 300+ volts of high current batteries
- two 9″ Warp motors, mechanically in series, with the brushes advanced

Or….two 8″ ADC. Warp, GE, or whatever.

- no transmission, just a rear end (around 4.1:1)

Yes, no tranny. White Zombie runs with a 4:57 ratio and smallish (but big for a Datsun 1200) 24″ diameter rear tires. It still hits 106 mph in the 1/4 mile due to its expertly crafted 8 inch Siamese motor spinning at around 6800 rpm with so far, no apparent damage from high rpm (fingers still crossed) I am planning on a rear ratio change to in fact, a 4:11 to allow the car to hit 115-120 mph and stay within a safe rpm range. I believe there’s enough off-line torque, so that the taller gear set will not detract from the 1.59 60 ft. time it presently does with the 4:57 ratio.

- electrically the motors are initially series for lots of torque, then via
BF contactors (Bubbas) are switched to parallel for lots of power

When I did the ‘Afterburner’ bypass with the 240V pack of Orbitals, it was indeed, done with twin Bubbas. The controller was completely out of circuit at that point and the motors were connected in parallel directly to the pack….quite the rush when the button was hit! Now, with the 348V Z2K setup, I uses a trio of Albright SW200 contactors….one for the series connection, the other two for the parallel connection, Both modes are with the controller always in circuit.

- in series each motor only see half pack voltage (obviously)
- in parallel the motors can see full pack voltage, however this is limited
by the controller to 170V to prevent arc-over.
- about a 6000RPM redline on the 9″ motors

Yes, and as stated, 6800 rpm @ 106 mph. The car actually goes faster than this, and with the pedal still down as it flashes through the traps, the speed is still rising to probably 110 mph or close to 6900 rpm with the Siamese 8 before we get out of it.

So, a few questions:

- it appears there is going to be a lot of contactors if this is going to be
a street vehicle as well as a fast race car:
2 contactors for main power

I use one, plus a manual disconnect.

2 contactors for series-parallel switch

I assume you’re talking 2 reversing type contactors. It can be done with three SP/ST contactors as well.

1 contactor for reverse (or is it two?)

With twin motors, it’s one reversing set per motor.

- how does one switch from series to parallel? If it was just the
contactors, that would be understandable, but it appears to be controlled
from the Zilla controller.

Actually, it’s controlled by the Zilla’s Hairball, not the Zilla itself. It can be done automatically by virtue of full throttle and the current ramping down to 1/2 the max selected current, or, with a manual control via a push button.

- is the series/parallel switched under full load?  Is it a real rough shift
(like drag race scarey - BANG?)

It doesn’t have to be when manually controlled, but if under automatic mode, yes….full throttle, yes, a big BANG with your  head against the seatback! For a more sane street driving experience, a manual control over the series-parallel contactors, where you switch them off throttle, results in very smooth operation that is seamless in effect with no banging, no tire squealing at switch-over.

3-26-06 Electric Nissan 240SX vs Modern Gas Performance Cars

May 1st, 2006

Hello to All,

A good ‘ol comparo is just the thing to put an exclamation mark on Matt’s recent achievement of blasting through the 1/4 mile in just 13.3 seconds, so I thought I’d educate those who may not be into performance cars, on just how powerful and quick Matt Grahm’s ‘Joule Injected’ electric 240SX is.

Admissions:

(A) I’ll mostly reference relatively new gas cars, since older gas machines are nowhere near as clean running as an electric car is, though there are two representatives from the 60’s muscle car era. For the most part, it’s today’s lower emission type performance machines vs Matt’s zero emission electric car. Also, it’s generally known that today’s hi pro gas cars are quicker and faster than their legendary 60s era muscle car brethren, though old farts stuck in the past don’t often realize this :-)   In fact, many of today’s hot 4 banger import machines can blow the doors off ‘most’ of the 60s era muscle cars, and they do it while passing stringent crash standards, clean air standards, and fuel economy standards, three categories the old muscle cars would all fail.

(B) Given two vehicles that run the same 1/4 mile ETs, one a gas car and the other an electric car, the electric is nearly always substantially quicker off the line and up 60 mph because of the electric motor’s huge torque at zero rpm. Thus, with  two cars that both run 13.5 seconds, the race goes like this…the electric jumps off the line and by 60 mph is perhaps 2-3 car lengths ahead of the gas car, by the end of the 1/8th mile the gas car is now picking up speed at a higher rate and is now pulling up on the electric, and by the end of the 1/4 mile, the gas car has caught the electric as they both flash through the traps. Both cars run the same ET, but the gas car has a higher top end speed, while the electric has a quicker 0-60…see how this works?

OK, on with the fun…..

(1) In recent years, to many folks’ astonishment, the once stodgy ‘old man’s car’ Cadillac has transformed it’s model lineup from blimped-out bulbous huge land yachts into America’s premium hi performance sedans. Today’s Caddys are muscular and fast and corner like sports cars. The top dog model is the CTS-V, a $52,000 400 hp road burner who’s borrowed-from-the-Z06 Corvette V8 jams it from 0-60 in 5 seconds flat and runs a 13.4 second 1/4 mile (2005 model). Road & Track magazine described it as having ‘explosive straight-line performance’. Guess what? Matt’s electric car beats it in the 1/4 mile! I estimate Matt’s car runs 0-60 in 4.5 seconds, too, so it toasts the Caddy here as well. If the Caddy has ‘explosive performance, I wonder how they’d describe Matt’s EV?

(2) OK you say, what about a real sports car? How about Porsche’s newest, the $70,000 Cayman S? This Boxter derivative with its midship-mounted 291 hp flat six rips 0-60 in 5.1 seconds and does the 1/4 mile in 13.4 seconds (2006 model)….Matt’s electric beats it in both 0-60 and the 1/4 mile run!

(3) How bout the new $35,000 2006 Charger R/T with its highly touted 350 hp Hemi V8? It too, would get roasted by Matt’s electric Nissan, since the Charger’s 0-60 of 5.9 seconds and its 14.1 second 1/4 mile ET are no match for Matt’s electric car.

(4) Just for fun, the 68 Charger R/T with a mighty 440 V8 rated at 375 hp (old hp rating) ran 0-60 in 6.5 seconds and managed a 14.9 second 1/4 mile ET. Lowell Simon’s electric Porsche would beat this car by a half second through the 1/4 mile! Matt’s car would be 1.6 seconds quicker…an eternity in 1/4 mile terms!

(5) Exotic? Try this….the $83,000 2003 Masserati Spyder GT has a 390 hp V8 and runs 0-60 in 5.0 seconds and has a 13.5 second ET.
What fun it would be, to find a well-healed dude in his Masserati, tell him your Japanese car has been converted to run on batteries, then leave him in the dust! Oh yeah, almost forgot to say it….Matt’s car beats this one, too.

(6) The $26,000 300 hp 2006 Mustang GT V8 runs 0-60 in an impressive 4.9 seconds and manages the 1/4 mile in 13.5 seconds, but it would get beat by Matt’s EV.

(7) In light of the above, the 68 390cid 335 hp V8 powered Mustang GT ran 0-60 in 7.8 seconds and did a 15.2 second 1/4 mile ET.

(8) The $32,000 2003 Subaru STi with its brawny 300 hp turboed flat four does 0-60 in just 4.9 seconds and runs a 13.3 second ET. OK, this car is a match for Matt’s EV, but the EV would still get it in the 0-60 run.

(9) The $50,000 2004 Audi V8 version of its S4 hi pro sedan, has 340 hp. It runs 0-60 in 5.4 seconds and the 1/4 mile at 14.0 seconds. Matt’s electric 240SX would blow its doors off.

(10) I saved this for last. The $36,000 Nissan 350Z sports car with its powerful 287 hp V6 runs 0-60 in 5.7 seconds and does the 1/4 mile in 14.3 seconds. Matt’s electrified Nissan beats the new gas powered Nissan by a full second in the 1/4 mile!

I hope you all had fun reading this, and I hope those of you who may not always follow the EV drag racing stuff will now have a better appreciation for what guys like Matt are doing to keep EVs in the spot light. I bet there are a whole bunch of dazed gasser folks who are still stunned by what they saw an electric car do at the Moroso Race Track the other night!

3-24-06 Hawker and AeroBatteries Team up with Plasma Boy Racing Again

May 1st, 2006

Hello to All,

While my friends across the USA in Florida are all ready tearing up the track, we’re still ramping up for the 2006 racing season. I’m happy to report that today, a pallet of 30 brand new Hawker AeroBatteries arrived at the dock of Northwest Handling Systems. I want to publicly thank Hawker, and especially Dick Brown of AeroBatteries for their unwavering support! Dick’s enthusiasm over our racing efforts has been awesome, and Hawker has been very generous in their sponsorship.

After a pretty heavy day of wrenching on forklifts with service calls all over the city, the stormy Spring day ended on a fun note as I and my ride-along younger tech arrived late returning to Northwest Handling System’s back equipment yard. There’s something very exciting about getting back as day’s light was fading away, opening the slider gate, and positioning my service truck to receive a load of feisty Hawkers. Unlocking the service shop’s doors (everyone had already gone home for the weekend) we went in to fetch the pallet of batteries. The fun started with me choosing one of countless powerful Crown electric reach trucks to do the deed. I chose an AC drive RR5225 stand-up rider-reach machine as the tool for the job at hand. Able to hoist 5000 lbs. straight up 25 feet with effortless ease, the 700 lbs. of AeroBatteries wasn’t much of a challenge for the powerful Crown :-) Still, loading 700 lbs. of batteries by hand would have been a lot of work. I drove the load outside down a ramped grade, and then positioned the forklift at the rear of my service truck. Using the Crown’s multifunction handle I raised the load, side-shifted the carriage to perfectly center the pallet, then used the reach function to extend the batteries into the back of my service truck…the hefty Isuzu truck barely noticed the extra 700 lbs. in back. There’s something very cool about using an electric vehicle to load batteries for my electric vehicle!

The batteries are now at my home, still in the back of the service truck parked in the shop driveway. Tomorrow, I’ll fire up my own electric forklift and use it to retrieve the pallet of batteries…more EV fun!

With a brand new pack and the other mods we’ve got planned, 2006 should be a fast year for Plasma Boy Racing!

See Ya……John Wayland

Madman.

Uh….Madman, not to try to take ‘anything’ away from Matt’s accomplishment, but duh….our track doesn’t even open until late April :-)
Living in the same Pacific Northwest area as I do, you of all people should know this. Unlike balmy Florida, we have to wait for drag racing weather to return after the Winter’s ice and snow, and the early Spring’s rains are behind us.

By the way, when will ‘you’ make it into your own Madman’s 100?  ;-)

Way to go, Matt and Lowell!

Congratulations to Matt Graham and Lowell Simmons for their outstanding
performances at Moroso Racetrack in West Palm Beach last night!

I second that!

Lowell set a new world record of 14.55 seconds in Miramar High School’s Porsche 944,
beating the previous record by almost 2 seconds!

14’s is moving! There’s many classic muscle car guys that would be seeing Lowell’s EV’s taillights!

Matt Graham also made history in his Nissan 240SX by being only the third (full-bodied) car ever
to break the 100mph barrier in the quarter mile!

Yes, that’s terrific, but the slightly lower speed run of 99 mph was done in a stunning 13.3 second blast! We’re talking just 3/10ths away from running 12s!!! I predicted Matt’s machine could run 12’s….stay tuned, it’s only a matter of time. A near 3000 lb. EV running low 13’s?? That’s quite an accomplishment.

Hello to All,

Ok, not exactly EV, but if anybody could help that would be cool. I need an AGM battery for starting an ICE lawnmower that has low self-discharge and long life. Probably around the 12-14ah range. I looked at the Hawker Odyssey 13ah.

You’d be hard-pressed to find a better quality battery.

They claim it’s really tough….

They are ‘extremely’ tough. Search the EV list archives for my many posts about ‘the Amazing Hawkers’, and many posts from others reporting the same.

>can sustain being left at 0% charge for weeks/months and still recover ….

Hmmm…that’s a tall claim. I ‘have’ had this exact battery taken down to zero volts and left there for three months, and upon a recharge, it came back without any cell reversals. Now, did it still have the same capacity? I doubt it. You can’t get away from permanent sulfation.
In general, it’s never good for any lead acid battery to do this.

>and sit for years…

This is absolutely true with Hawkers. I have quite a few 8 year old Hawker 16 ahr versions that have been sitting for long lengths of time that still work well. Again though, there is going to be some permanent sulfation that will occur if you let a battery sit so long unused and uncharged, so they really can’t sit for years and power-up to 100% capacity.

….but for $80+ seems like a bit much for just a 13ah battery.

Not when that same battery can deliver 500+ amps repeatedly without any noticeable degradation of the battery! 28 of the slightly larger 16ahr version of this battery powered my race car at 750 amps for 13 seconds to a world record back in 2000. Hawker toughness and long life are legendary on this EVDL. The internal inter-cell straps are very robust and can sustain high currents without melting. Small Hawker batteries can deliver HUGE currents and are worlds away from ordinary batteries of the same size and weight. All of these traits may not be applicable for you though, for merely starting a lawnmower.

Speaking of Hawker, what are people’s general opinion on Hawker batteries?

3-12-06 High performance couplers (and White Zombie mods)

May 1st, 2006

Hello to All,

Jimmy wrote:

This is a question for you guys that like to do mega burn-outs.

OK, I guess that qualifies me :-)

Are there any tips on
materials for couplers used in the high performance applications like the
Current Eliminator or some of the NEDRA cars?  Do you guys use tool steel
or just a cold rolled bar stock?

When running the twin 8 inch motors in White Zombie equipped with a battery pack capable of delivering 2500+ amps of current and after using the brutal 2500+ amp ‘Afterburner Bypass’ a few too many times, the coupler between the motors, and the cold rolled steel motor shafts, keyways, and the key stock pieces, were getting torn up and worn to where something was going to break. Perhaps the wear was just from pieces not quite being machined just right or aligned perfectly. In any event, when we designed the new Siamese 8 motor, we wanted the shaft material to be strong. Dutchman Motorsports chose a high strength rating of stainless steel to machine the super long shaft out of. Maybe Jim Husted can recall the exact material number and its hardness rating? If my memory serves me correctly, the cold rolled steel shaft of a stock motor is something like a ‘30′ rating where the special stainless shaft has a ‘130′ rating…Jim? This shaft has a splined output that mates into a beefy Spicer U-joint yoke. You can view it here:

http://photos.plasmaboyracing.com/buildsequence/Shaft_Spicer

We also wanted to have the new Siamese 8 setup to be as simple as possible. The new design got rid of the obvious, the two separate motors and their motor bracket-mount in favor of a single unit that still acts like two motors (25 lb. weight savings), and so it also eliminated the motor-to-motor shaft coupler. It also got rid of the rear motor output flange, the flanged U-joint coupler that attached to it, the heavy all steel two piece driveline, and the center support bracket and carrier bearing assembly. Now, there’s just the Siamese 8 with its splined output shaft, and a light and strong aluminum driveshaft (10 lb. spinning mass weight savings) that slides onto the motor shaft.
The new motor is also 7 inches shorter than were the twin motors on their mount bracket, so the Siamese 8 sits flat and parallel to the ground, unlike the old twin motor affair that was so long it had to sit on top of the front transverse frame rail of the car and poke downward so the back end of the rear motor would clear the tranny bell housing body tunnel.

If things go as planned, the car will soon shed even more weight when we change out the heavy steel case Ford 9 inch differential  and replace it with a much lighter all aluminum unit from Strange Engineering. The continued weight reductions, plus a taller gear set in back, high rpm field weakening, and a fresh battery pack (thank you Hawker AeroBatteries), should help us achieve this year’s goal of running an 11.5 @ 115 mph…on DOT tires.

Thanks Jeff, I appreciate this very much.

I do take issue with Neon John’s comments that I was ’simply given’ batteries and a one-off custom motor.
Simply given batteries? There was nothing simple about arriving to today’s status of being sponsored by Aerobatteries and Hawker. Do I appreciate it? Of course I do. But to imply it was simple seems to be quite a slap in the face.

As to that motor that was ’simply given’ to me as well, think again! The twin motors that were morphed into the Siamese 8 were my motors, motors I paid for from my work in the early beginnings of NetGain and the build-up of what was then known as Bad Amplitude, the NetGain rail dragster back in the Chicago area. Though I received sponsorship from Dutchman Motorsports while we were developing the custom stainless steel armature shaft in the form of deep discounts, some freebie items, and lots of personal free labor and moral support from the Dutchman himself, I paid money for materials. Jim Husted did donate all his time and labor, plus copper, misc. motor parts, and shop materials…again, very much appreciated. Jim however, would be the first to tell anyone that I wasn’t simply handed a one-off custom motor. Tim Brehm, too, was a big part of the Siamese 8 project…so was the Madman Rich Rudman, and along with the Dutchman, the three of them made long trips over into central Oregon to Jim’s shop in Redmond. The five of us spent many late night hours huddled around lathes, presses, and other machinery at Dutchman’s machine shop. I also received lots of help, as I always do, from Marko Mongillo at the metal shop, where we made the heavy duty motor brackets. Of course, I return the favor when I help Marko, as I’ve been doing for the past month or so as we’re working on his ‘Baby Blue’ re-conversion project.

The amount of time and energy we all put into the Siamese 8 project would exhaust most folks, trust me! I’d say I’ve got close to 3K of my own money into this one-off custom motor. I deeply respect Jim Husted and am in awe of his fine craftsmanship, but let there be no mistake, all aspects of the Siamese 8 had to be approved by me, and most all of the racing tricks put into this motor were learned the hard way, by me. Keep in mind also, that I openly share all info about everything I do in regards to racing and the items we either design or modify. One of my goals is to make it easier for others to join in and race and or daily drive their EVs. You can check with anybody, and you’ll never hear one word about me slamming the hood shut, or cloaking the car from view, or refusing to share what I know with other competitors, friends, fellow racers, or just strangers interested in what we do. In fact, I’ve kept everyone on this EVDL abreast of the entire project with my constant postings, so I find it odd that Neon John would make the comment ’simply given’….oh well.
