I have most of the components picked out for a buck converter. 35 amps at 144v should be enough for 35 mph travel I think, if I understood that link that Ben posted earlier in the thread. Heck, the controller doesn't even need to tell the charger to turn on. We could save that for later. It could just be a basic good heavy duty constant current charger that you turn on whenever you feel like it. Flip a switch turning on the charger, and it will take care of turning on the electric start generator. It can ramp up the load at any rate you want, or do whatever the code says to. I think that would be a good option at first since then I wouldn't have to do a new control board for the controller.
Ben, do you have a student ID card? There's a place that has a special for $33 for making a new PCB, with no setup fees. I could afford that. Get a dang charger going! Just imagine a $2000 Chevy volt that doesn't catch on fire. hahaha.
