You either have a mechanical linkage that rotates the pot 270 degrees when the
accelerator pedal moves from top to bottom. Or, you use a pot that goes from
0-5k ohms with only (say) 90 degrees of rotation (whatever is convenient for
your car's throttle linkage).
The Curtis potbox takes the latter approach. They use a custom potentiometer
that only needs90 degrees of rotation to go from 0 to 5k ohms of resistance.
You can accomplish the same thing by using a regular 20k pot, and not using the
parts of the rotation past 5k.

I'd like to see a line drawn representing it's rate of discharge.
Because I doubt it's linear in the sense it goes from 3500 V to 0 like
this: \ Or even less of an angle. It might be flat then drop off
suddenly and rapidly at some point? Isn't that how capacitors usually
discharge?
Any progress on the 3500 V Zilla Otmar? ;) Still at 2,000 amps or so?
How hard is it going to be to make a controller of sorts for this 3500 V device?

I think we are all waiting to here when we are going to Alaska before setting a
date for the Wayland Invitational :-) When are we going to be running the
Midnight Sun races? I haven't been back to Alaska since I left there at the
age of 3, so I'm looking for an excuse.

This article was featured in a recent CalCars News release. It is very
complete, and would make interesting reading for any one on these lists.

Best article I've ever read on Li-Ion battery technology.
Thanks for posting this link,
