Physics question, what is the horsepower delivered to the drive wheels?

The power/control system of an electric car consist of a 48 volt onboard battery pack, electronic control/drive unit, and motor. If 180 amps are drawn from the batteries, how many horsepower are delivered to the drive wheels?





Best answer to whoever has the complete solution





thanks|||Voltage = 48.


Current = 180A.


Power = (48 x 180), = 8,640W.


1hp = 746W.


(8,640/746) = 11.58hp., neglecting inefficiencies in electronics and machanics.
