How somebody can increase the voltage going to the motor?

LMK if you find out how to do that, I'll be waiting for the "I just fried my inverter, Help!" thread.

 

i must say, i don't recall this ever being asked. i suppose anything can be done, but it might be cheaper to buy a gen III or other hybrid.

 

I think you'll be the first, and then you can be that company. Have you looked in the New Car Features Manual (for either Gen 2, Gen 3, or both) to see how the voltage boost is currently done? (There are boost circuits in both Gen 2 and Gen 3, but by different amounts, of course.)

You'll basically be engineering an upgraded inverter and also cooling system for both the inverter and transaxle, to cope with your planned 30% to 60% increase in power being handled by both. Then you'll have a kit you can maybe get Danny to carry on the PriusChat shop. The free market is a beautiful thing.

edit: my mistake, you could be engineering for a 70% to 150% increase in power capacity (proportional to volts squared) ... your cooling system might look quite different from Toyota's.
