I am looking for ideas on AC electric cars. i have seen the kits that use an AC motor and an inverter unit to convert the battery power for use in the motor. I am wondering if there is any advantage to using a VFD and an appropriate size generator? I know locomotives use the motor/generator set up with good efficiency. if i wanted to use a 20hp induction motor i wonder how i would pick a VFD and a generator so as to make a reliable set up? thoughts?
The Toyota Prius uses an AC motor Nimh batteries and a 4 cylinder petrol motor. It has all the control circuitry for regenerative braking, etc already developed. It has no provision to charge the battery from teh household supply. All power comes from the petrol motor. There are 3 models shown at the site below Electric Motor Operating Voltage 1997, 288V 2000, 273V 2003, 500V Power 1997, 40hp 2000, 44hp 2003, 67hp
