What is the rated power and torque of the motor?
Thanks for the compliment.
The motor output is more limited by the batteries and controller settings. We have a 1000 amp capable controller, and 144 V nominal battery voltage, so the theoretical max kW is around 144 kW. In practice the motor is only about 85-90% efficient, and we're only running at 700 A max to preserve the batteries. So our actual motor power output is around 85-90 kW. From the motor performance curves that are generated at 72 V, I can extrapolate and guesstimate the torque peak is around 270 N-m. The controller we're using is pretty sophisticated and designed for soft starts etc, so I think it blunts a bit of the "instantaneous torque" that people talk about from electric motors as it ramps up the current gently. It's definitely no ball of fire - probably very similar to the original car but a bit quicker off the line, and also most noticeably you don't really need to put your foot down to maintain speed when going up a hill - it just pulls up the hill with all the torque of the motor.
