Calculating Current Draw for an Electric Car Motor

Explanation:

The formula of electric power is given as follows:

Power = (Voltage)(Current)

Current = Power/Voltage

In this question, we have:

Power = 45 KW = 45000 W

Voltage of Battery Pack = 340 V

Current needed to be drawn = ?

Therefore,

Current = 45000 W / 340 V

Current = 132.35 A

The motor needs to draw 132.35 Amperes current from the battery.
