I agree nickel is a lot more straightforward, but I can't see most people going with only electric vehicles without at least 100 miles of range. People may not travel that far frequently necessarily, but having the option (at least for my family) is a requirement. Nickel/lead acid is a good option for second vehicles, complimenting another gas vehicle, but if you want to replace gas vehicles I think Li-ion is the way to go.

edit: I could be wrong, but I think Li-ion charge quicker.

We did some research into batteries for our hybrid electric race car. Ultimately we choose ultra capacitors because of their very high power density. Lithium Ion batteries have very good energy density for battery, but poor power density. They charge at around .8 C/s. The charge cycles are extremely complicated compared to other batteries and if not done ideally result in reduced life at best and explosion at worst.

Well, you're going for a race car though. A normal car doesn't necessarily need power (energy per second) so much as just energy period. I mean it's the difference between a muscle car and a minivan, of course the minivan doesn't have the acceleration of the muscle car, but that's not what you need in a minivan.

My dad did tell me about the rather exotic charge cycle, but you get the right controller and it should be okay. Everytime you fill up at the pump at best you get almost all of the flammable fluid into the tank and don't get too many fumes everywhere, at worst you blow up a small county.

If you didn't know already there are a significant number of people into electric vehicle racing, and it's actually really amazing what they can do. Since the low end torque of an electric isn't even comparable to a gas car, they have made electric cars that absolutely destroy any gas car it goes up against in I think the quarter mile drag.

I would be interested in a site for your organization/race.

That's why voting for O'bama or McClain is dumbest thing anyone can do.

...says the man who can't vote for either.  Since, here in America, we have the two party system, and you just knocked out the two which 90% of the population would vote for... who would you prefer (who is actually still in the running for President of the United States?

I am curious.
