I talk about the kart here: http://www.diyelectriccar.com/forums...313#post247313
Our 2 karts were pretty much identical, 48V, AC15 drives. Rules limit race energy to 8640 Wh and peak power to 14 kW. Wide variety of systems and battery types, all Li and mix of AC & DC motors.
Track was very bumpy so rattled the poorly constructed karts out early. I think maybe only 8 or 9 still running at end. Lots of action (yellows and a few red flags). I think all karts used the pits. A lot for repair. Not all did battery hot-swap, but we did. I don't think anyone did more than one swap. Our #19 lost the chain on-or-abouts lap 75 and retired.
I was volunteered to do technical inspection and therefore had to let the student teams run the race by themselves. They did good and learned a lot I'm sure.
BTW, this competition is open to all secondary education institutions (colleges, universities, trade schools, etc.) worldwide. Two from the UK raced, Coventry and Warwick. Anybody out there interested? Go to http://www.evgrandprix.org/
So last week, in between the Infineon and Indy evRaces, I presented a session on the evGrandPrix at EVS-26 in LA. Nice show out there.
