How much power (watts per pound? KW?) do you need to run an electric car?


Hi, Bill -

According to Electro Automotive:

A small car (2500lbs. factory curb weight) uses an AC motor that pulls 43KW peak, 14KW continuous from your electric car's batteries at 156 volts.

A large car (3500lbs. factory curb weight) uses a larger AC motor which pulls 78KW peak, 34KW continuous at 312 volts.

Lynne


P.S. Here's an article about AC vs. DC electric car motors.

For an electric vehicle with a max speed of 80 KM/hour (about 50 Miles/hr) and 600 Kgs (1325 lbs aprox.) of weight (curb + payload) what type of motor would work the best? This is for a three wheeler.
