I like the idea! The Volt pack would easily supply enough power (see attached test report). What about just using the leaf pack? It is probably 100 kg heavier, but is 24 vs 16 kW-hr, and would make it simpler - only one donor vehicle.

Our Tesla Cobra EV finally hit the race track in June and we have now run 3 races and a number of test sessions with it. The performance has met our expectations and has surprised a lot of people! As predicted, range, length of time to recharge, and battery/motor temperatures have been the...

Re-using the Kia Charger was quite easy. A number of interlock conditions must be met for the charger to operate. The hardware ones were easy as Kia publishes the wiring diagrams. However, some information comes via the CAN bus such as drive state (must be in Park), parking brake, door...
