I have an idea that could potentially change the way electric cars are charged but I need the smart people on this forum to tell my why it's not a good idea. I'm not sure how efficient the on-board charger is, but what if the source electricity from the charging station was used to spin the motor to act as a generator to DC-charge the battery, just like regen? The motor is somewhat efficient as a generator but I'm not sure how efficient it is vs. the on-board charger. If it is almost as efficient, then this idea would negate the need for chargers (single or dual). The motor runs on AC, right? To me, this seems like a cheap and simple way to charge the car and would allow you to maximize charge rates based on the amount of amps available with no need for dual chargers, etc. Plus it would sound cool having the motor spin-up as a generator while charging :biggrin: I know this sounds silly, using electricity to generate electricity, but you're using electricity for the same thing when charging the batteries through the charger so it's not really that much different. It all depends on the efficiency of the motor as a generator.
