How to go fast while flipping the bird to the oil monopolies: High performance electric cars

Many believe battery electric cars are slow and tend to resemble golfcarts. This is not true.

You see, a series wound DC motor produces its peak torque at zero rpm. A series DC motor's torque is also proportional to an exponent of the armature current(exponent varies from two at 0 amps to about 1.05 at 2,000+ amps due to changes in the properties of the copper and steel of the motor as the magnetic field strength increases). You put about 1,000 amps and 200+ volts through something like an Advanced DC 9'' series wound electric motor with 15 degree brush timing, and you're going to make some *BIG* torque and horsepower numbers. This often results in many a broken drive axel or stripped gears.

Here, let me demonstrate with the following videos:

Battery electric RX7 SPANKS Dodge Viper. Mazda is named "Maniac Mazda" and was driven by Roderick Wilde. It was powered by two ADC 9'' series DC motors and two Zilla 2000 amp controllers at the time of the race:

Electric Datsun 1200 barely got defeated by a Viper, however he blew a battery. Named "White Zombie" driven by John Wayland". It has routinely dusted off Vipers in the past. At the time of this race(years ago), it was powered by a single Kostov 11'' series DC motor and a 1400 amp Zilla controller:

http://68.101.177.4:81/vids/Wayland_vs_Viper_256k.WMV

Electric Porsche 914 "California Poppy" driven by Otmar Ebenhoech pulls 1/4 mile in the high 13s vs. electric Nissan 280Z named "Silver Bullet" driven by Tom True pulling 14s. The 914 is powered by a 2000 amp Zilla controller and two 8'' Advanced DC electric motors, and the 280Z by three DCP T-Rex controllers and three Advanced DC 8'' motors:

"Daulin' 7" electric Mazda RX7 driven by John Brown vs. "White Zombie" electric Datsun:

Here Wayland takes his Datsun 1200 into the 12 second 1/4 mile 100+ mph territory while at the same time raping a Mustang 5.0. In this video the car is powered by two Warfield 8'' series DC motors, 1400 amp Zilla, and a 'contactor bypass' that can bypass the controller's amp limit using a contactor to send current straight from the batteries to the motors for 3000+ amperes of current:

In this video, Wayland's car, driven by Tom Brehm, rapes a Vette! Installed is a 348V pack of Hawker Aerobatteries, twin WarP 8" series DC motors, and a Cafe Electric Zilla 2k controller.

Here’s a video of various electric cars doing burnouts:

http://www.seattleeva.org/NEDRA_BurnOffs.mpg

Here's some electric car race, burnout, 'under the bonnet', and even wheelie pictures:

The four images below are an electric VW Cabriolet smoking its tires in two burnouts with an electric Ford Fiesta named "Goldie" and a little electric Renault Dauphine with a fairly *****y attitude.






The following 9 images are of John Wayland's electric Datsun 1200 named "White Zombie" doing a wicked burnout and of a race with a Dodge Viper.











The following two images contain Roderick Wilde's electric Mazda RX7 named "Maniac Mazda" popping a wheelie and destroying a Viper off the line...




The CommuterCars Tango does a burnout:



And, time slips certainly don't lie, either:




Not only that, but Lithium Ion batteries are allowing electric cars ranges in excess of 200 miles per charge. If quick chargers were installed for these batteries in our public infrastructure we could see 20 minutes charge time. Since no automaker is mass producing EVs and using said batteries, they remain prohibitively expensive. But is it theoretically possible to make a fast, long range EV for a price your average Joe would be able to afford? Yes! But that is within the realm of politics, another topic.

Here's some statistics and pictures of some respectably fast electric cars that have been built by both small businesses and individual people that could feasibly be duplicated today:

Trucks, sports cars, limousines, you name it. The fact remains EVs are now competitive in performance and can be very fun to drive. They can also be damn sexy.

One might comment that they don’t top out at a high speed, but that is often the case when they are using only one gear ratio in a direct drive setup. Use a transmission and an EV could easily hold its own in the top speed category, as can be noted by the Maniac Mazda or Otmar’s 914. However, have enough power, and even direct drive setups can still break world records(or come close to it), like the Eliica and its insane 250 mph top speed, for instance. Yet how much have you heard about the Bugatti Veyron or the Koenigsegg CCR instead?

Interested? Want a race car that isn't a maintenance *****? Or do you just simply want a spirited and quick daily driver that's independent from rising gas prices? Maybe you're one of those rare closet granola crunchers that just so happen to have a lead foot? Perhaps you want something as different as possible so you can humiliate people at the track? Does the mere idea of having the nastiest Joule-Injected Suicide Machine on the road give you a boner? Maybe it's time to build one. Don't be afraid to ask around.

I will make another topic dealing with conversion advice.

In the meantime, don't forget to check out the following sites detailing high performance electric cars:

www.plasmaboyracing.com: This is John Wayland's site. It has videos and photos galore of his two electric Datsun 1200s that you need to see if you are interested.

www.nedra.com: National electric Drag Racing Association. Want to race EVs? Just plain interested? Do yourself a favor and visit this site. They are sanctioned by the NHRA!

www.powerofdc.com: The Power of DC drag races are held every year at the Mason Dixon dragstrip near Hagerstown, Maryland, every summer.

Also of concern are the 2006 High Voltage Nationals at the Route 66 Raceway in Joliet, Illinois. John Wayland will be attending with his Viper-killing electric Datsun 1200, "White Zombie". The races are open to alternative fueled vehicles only, but anyone can attend. The following information was provided:

From: Chip Gribben
Date: 12/10/05
Subject: NEDRA Announces the 2005 High Voltage Nationals

Route 66 Raceway in Joliet, Illinois will be holding the HIGH VOLTAGE NATIONALS May 13, 2006.

The event is being organized by High Voltage Racing, the Fox Valley Electric Auto Association (FVEAA) and is sanctioned by the National Electric Drag Racing Association (NEDRA).

All pure electric vehicles (2, 3, and 4 or more wheels) are invited to participate, either as a static display or drag race in the NEDRA event.

All alternative fuel vehicles (cng, hydrogen, propane, bio diesel, veggie oil, steam, etc.) and hybrids of all makes and fuels are also welcome to participate as part of the Alternative Fuel Vehicle (AVF) Expo which is also being held at the Route 66 Raceway.

Prizes include trophies and cash awards.

This is in conjunction with the Joliet Township High School's (JTHS) Alternative Fuel Vehicle (AVF) Expo.

The event will also be held in conjunction with the 5th EVer EAA All-Chapters Conference that same weekend from May 12 to 14th which will also be hosted by the FVEAA. The 5th EVer is a gathering of EAA Chapters to conference about opportunities to promote and develop EVs.

The HIGH VOLTAGE NATIONALS will be an annual event and joins the BATTERY BEACH BURNOUT as NEDRA's two newest events for 2006. Stay tuned for more information as it develops.

Press the Forward button, step on the gas (oops! Accelerator) pedal, and savor a noise not unlike the whine of a jet engine as you pull away. Because torque is almost constant, acceleration is felt evenly all the way to the top speed of 85 mph.”

[2] Sacramento News & Reviews, “Electric Smoke Screen”, by Nick Budnick, 7/6/1995, Page 19, –“ The rhetoric obscures the great strides electric vehicles have made in the last several years. A Southern California firm co-owned by Alan Cocconi, a former researcher with GM's electric vehicle program, has developed a 200-horsepower motor that propels a four-seater converted Honda Civic from zero to 60 mph in a mere 6.2 seconds, according to the July Road & Track magazine. The vehicle needs only two hours to recharge using a washer/dryer outlet. Of course, it costs $75,000; but Cocconi told the News & Review the high price is because it is a prototype, hand-built by the company's seven employees--not by an assembly line. "If you build 1,000 a year, it would be below $30,000; and if you build 10,000 a year, you get it down to around $20,000," he said.”

[3] http://www.acpropulsion.com/ACP_history.htm –“In 1994, AC Propulsion introduced the AC-150, a 150 kW (200 hp) integrated drive system for compact to midsize passenger cars. At that time, AC Propulsion developed an electric vehicle based on a Honda Civic hatchback to demonstrate the AC-150's capabilities. Tested by Road & Track, that car achieved a 0-60 mph acceleration time of 6.2 seconds. In June, 1996, the same AC Propulsion EV, with 47,000 miles on it, set a range record of 145 miles over the "Pomona Loop" an urban driving circuit used by Southern California Edison to evaluate EVs. Energy consumption over the range test was 126 Wh/mile, the equivalent of 266 miles per gallon. No other EV, including advanced prototypes from major automakers has matched these levels of performance and efficiency.”

[4] http://www.acpropulsion.com/Media%20storie...d_and_Track.htm –“The muscle behind the gentle-looking Civic is the AC-150 Drive System that draws its power from 28 sealed, no-maintenance Optima lead-acid batteries. They are stored longitudinally along the center of the car, and the whole pack can be lowered to the ground, via hand crank, and replaced in 30 minutes. A full charge can be taken on in just one hour (240 volts, 80 amps) or in two hours from a household washer/dryer outlet. Pop the hood and notice the controller box-the real heart of the system; underneath lies a high-efficiency induction motor that produces 200 bhp between 6000 and 12,000 rpm. Unlike internal combustion engines, the electric motor's maximum torque of 165 lb. -ft. is constant from zero to 5000 rpm, which translates to rocket launches at the drag strip. The Civic gets to 60 mph in just 6.2 seconds, aided by traction control to keep the narrow, 60-psi Goodyear Invicta tires from turning to a gaseous state.”

I have no real stats to prove this, but my seat of the pants estimates have served me well over the years."

With 1200 amp power draws, 0-60 is in the low 6 second area, range when driven hard is 15 miles, 20-25 miles when driven moderately, and up to 31 miles or so when driven at grandma-type 35 mph constant speeds.”

[8] www.mail-archive.com/ev@listproc.sjsu.edu/msg04253.html -"I'm pretty pumped up about Blue Meanie's scheduled revamp. I am committed to doing it at 204V. Because the Orbitals are 4 lbs. lighter than YTs (40 lbs. vs 44 lbs.), there's enough weight savings in a 156V pack of 13 (42 lbs.) to add a 14th battery and still have the car weigh pretty much the same. Taking this logic a bit further, adding four batteries at 160 lbs., minus the 42 lbs. weight savings from the 13, makes the new 204V pack weigh just 118 lbs. more. Besides blistering performance (the top speed should be scary), it will have an increased range to 35-40 miles, I think."

'less' weight in batteries than White Zombie, and by rolling on skinny LRR tires, the Meanie's 13 Optimas at 585 lbs. can take that car 25 miles per charge when the batteries are in top shape. It's therefore reasonable to assume the with 100 lbs. more in pack weight, better efficiency due to running high voltage with very low amps for cruise speeds and because of less spinning mass (no dual motor shaft coupler and that aluminum driveline), but with more rolling resistance due to its fat drag tires in back, I'm thinking with the rear tires inflated up to 35 psi instead of their usual race pressure in the 15-18 lb. area, that White Zombie will do about 25-30 miles per charge.”

[40] Otmar Ebenhoech in an email to me describing the range and top speed of his electric Porsche dated Monday, September 6th, 2004–“Me: Also, what is the range per charge of California Poppy if driven at 60 MPH speeds? Otmar: About 20 to 25 miles. Not much. I could optimize more for range, but I think the dual motors are killing the efficiency and the big transaxle doesn't help either. Me: What will it top out at? Otmar: I haven't taken it over <speed omitted>, In fourth gear I'm guessing it would do 140 mph.”

[41] http://www.mail-archive.com/ev@listproc.sj...u/msg05383.html –“ So there I am, minding my own business, driving home in my old electric 914 "California Poppy". It's just a usual errand. Tonight I'm test driving a Z2K while returning from a nice Sushi dinner treat, celebrating having finished another batch of controllers. I'm down to about 50% capacity with eight amp hours down since the pack is dropping off a bit early lately. (gotta find the stinker battery in the pack someday) I'm on Alma expressway, a long straight 35 mph posted limit road that is nice for high efficiency driving. This means it's flat, 45 mph is the norm and the stoplights are far apart. At the first red light I pull up to the crosswalk next to a silver convertible Mustang with Florida plates and the top down. The 5.0 on the fender tells me this 30ish guy enjoys a little speed. I glance over and we exchange that slight nod of acknowledgement as guys in sports cars are prone to do. The light turns green and I take off normally. I'm not trying to save energy at this point so when I say "normal" that would be just fast enough to avoid squealing the tires. It helps that I've got the series mode current turned down to only 1600 amps so my normal start happens to be pedal to the metal. Normal as in 0-60 in 5 seconds normal... Mr Mustang is clearly not expecting this so I leave him behind as I normally do to everyone. I let the car shift to parallel mode, feel the strong pull hit me in the back and then let up to avoid breaking 50 in this quiet area. Mr Mustang catches up with me and hangs back just a bit, presumably to take in my many stickers proclaiming "Zilla Powered", "Powered by 100% American Electrons" and Zero Emissions Vehicle". I'm guessing it was a bit too dark for him to make out the "Eat my Volts" sticker on the rear window.”

[44] Otmar Ebenhoech in an email to me describing the efficiency of his electric Porsche dated Friday, November 19th, 2004–“I run the Eco Contact tires at 55psi. I have 0/0/0 alignment. I fixed the dragging brakes and run red line transmission oil, but not the thinnest since I'm worried about high load wear. I get about 240 wh/mile at 60 mph. The math says 170 wh/mile should be possible, but I think the dual motors and large transmission hurt that. I could add a belly pan, should help a lot, but I'd like to first know why the rolling drag is very high.”

[45] http://www.evsource.com/articles/orbital_optima.php –“One of the wonderful things about the EV racing community is how we help each other out. In the past when Plasma Boy was in a bind I was there to help him out, so I figured I'd see if he might be able to help me out here. John did not let me down. He dropped everything, worked his contacts, wrote some glowing emails, and before I knew it the super folks at Exide were sponsoring me with a new set of Exide Orbital Marine deep cycle batteries. Thanks John! Meanwhile, while waiting for those I was cranking on a fresh Z2K controller for the Madman Rudman, and he was shipping me a fresh PFC 30 so I can take a little better care of these new batteries. I was eager to get the Orbitals in the car for the documentary, and so had neglected to do some real basic research like checking the height. In the rear I have two layers deep of eight batteries each. When I dropped the first battery in I had that sinking feeling that usually prefaces a lot of work. The Orbitals were 3/8" taller than the Optimas. The racks were not tall enough. I spent much of the next three days with the help of Jos Goble remaking the battery racks to hold the extra height of the Orbitals. Despite the extra work, there was still time to wash the car and put a couple cycles on the batteries before the abuse was to begin. For break in I ran only 800 amps in order to be nice to them. Saturday morning sunrise found myself, Clare, and three people making up the film crew gathered outside my house. They followed me to a parking lot a mile away where we had permission to do some filming. On the way there I was driving rather carefully in order to save battery power for the show. We pulled in and while the others unloaded gear the director came up to talk to me in the car. "Could you just do a small burnout here so we can get a idea for what we are filming here?" He asked. I thought he might be a little concerned with my tepid driving on the way over there and I couldn't quite read his expression. I said that yes, that would be no problem. With him standing right next to the drivers door I punched it and released full Zilla power backed by fresh Exide Orbitals into those cold Eco Contact tires. Of course they instantly spun up and spewed smoke. I hooked the car around to the left and then fish tailed off in the opposite direction leaving two wavy black lines of rubber on the pavement. When I returned to the director his expression had changed considerably. He was all smiles and enthusiasm. Could I do exactly that again but heading right toward the cameraman? Aww shucks, I guess I could. :-) We spent the day filming the Poppy, doing interviews and some road shots. All the while, between shoots Rudmans PFC 30 was keeping the batteries topped up. The film crew were a bit surprised that it only took an hour for the car to be topped up and ready for more filming. So anyway, that's how the Porsche got a pack of Orbital batteries installed...”

Good paper toecutter.
Sheesh. Ok, ok the 911 project will turn electric during its rebirth/mutation. With the coming of li-ion and other advancements it's obvious that electric cars are going to be a viable option to combustion engines, and soon!
So what are the best references for designing and buying components? What forums are best for getting smart on this technology and help for a ground-up conversion project?

I thought I recognized those pictures from Woodburn drag strip. lol

I never knew there were so many EVs here in Oregon!

For controllers, the most accessable and powerful currently available are the Zillas, designed by Otmar Ebenhoech. His page is http://www.cafeelectric.com

If you want to get ahold of someone who knows how to modify motors, talk to Jim Husted. You can find him on the EV list. He built the Siamese 8" motor used in the White Zombie, that pulled many 12 second 1/4 mile passes. You can find him on the EV list, which is linked towards the bottom of this post.

Here are some places you can buy parts for EVs from(This is by no means all-inclusive, but a good list):

http://www.grassrootsev.com- Controllers, motors, other parts, and Steve Clunn sells already assembled conversions.
http://www.evparts.com/firstpage.php- Everything you need for an EV except car-suitable batteries.
http://www.electroauto.com- Sells bolt in kits for vehicles like the VW Rabbit, along with individual parts. Also sells Solectria AC drives.
http://www.metricmind.com- Sells AC Drives and Brusa chargers. Expensive but very good parts.
http://www.ev-america.com/- Another parts store.
http://www.canev.com/- A parts store for Canadians.
http://www.cloudelectric.com/- Another parts store.
http://www.evsource.com/- Sells Zilla controllers made by Caf? Electric.
http://www.kta-ev.com/- Sells parts and bolt-in kits.
http://www.go-ev.com- Great source of 8??, 9??, and 11?? DC motors.
http://www.manzanitamicro.com/- Your source for the Power Factor Corrected charger, which is much more efficient than a Lester or a Russco, having 92% average efficiency instead of the 75% efficiency or so of a budget charger. Some PFC chargers also allow fast charging with the right outlet.
http://www.trojan-battery.com/- Trojan golf cart flooded lead acid batteries can be ordered direct from their site. They are an excellent option for inexpensive highway capable conversions.
http://www.usbattery.com/- Like Trojan, this is another widely used flooded lead acid battery for conversions.
www.exideworld.com/products/automotive/exide_select_orbital_XCD.html- Exide Orbital batteries. These are what you want for an EV that is anywhere from normal performance to a full-fledged suicide machine with too much horsepower for its own good.
http://www.austinev.org/evtradinpost/- This is the EV Trading post. If you don?t feel like building your own electric car and would rather buy a conversion someone else built, this is an excellent place to look. This is also an easy means to pickup used parts for cheap and save a lot of cash on the conversion.

What forums are best for getting smart on this technology and help for a ground-up conversion project?
Get on the EV list. It's not a forum, but a mailing list. It is the most valuable resource you will find when it comes to getting advice/help for your project. http://www.evdl.org/help/ People from around the world discuss electric vehicle technology and its implications, and answer questions about converting cars to electric and help people through the process. They don't like discussing politics, as plenty of people of all views are there, and they prefer to keep it on topic about EVs. A lot of much needed technical advice is found there.

Join the mailing list, don't be afraid to ask questions.

There are two books you may want to read:

"Build your Own Electric Vehicle" by Bob Brant: Details all of the calculations you would use in designing your conversion, and gives you tips on selecting the chassis and components to meet your needs. The technology covered in the book is a little outdated, BUT it is still extrmely relevent for use. Don't pass it up.

"Convert It" by Mike Brown. Covers the process of converting a car in-depth, step by step. You'll want this if you're building an EV. Covers much of what is needed to keep your car roadworthy and safe.

Nope all the batteries are under the floor making most of the 1100lbs of weight at the wheel center or below it. It sticks to the road like glue. It is simular to my Bladez scooter with 3 23lbs Hawker batteries in the frame - like driving a flat rock . . . very stable.
