I can't believe I've missed this thread! This is awesome. Holy cow! Very professional videos, too. 324v. That's amazing. I bet a budget AC conversion could use small older 12v batteries because the current draw would be so low. You would get great range. This is really exciting. Keep up the great filming, Ben! Did I miss where he got his motor? Is it a budget industrial AC motor, or something designed for AC electric cars?

For that voltage, you would want to go with IGBTs instead of mosfets in the controller. You know, there are lots of 1200v 600amp surplus IGBTs sold on Ebay all the time. I bought 4 last year for $50 on Ebay, but got greedy and sold them one at a time for like $30 each. They are harder to parallel than mosfets, because of thermal runaway, but maybe if they were kept cool. Oh, man, this would be fun!

I can't wait to see how it drives, and what sort of range he gets, and Amp*hr/mi, etc..., etc..., etc...!!! Yahoo!
