# How the sizing of electric motor is done for a electric vehicle?

I have calculated the resistances encountered by the vehicle. Now to find the required power i used formula

                    Required power= Total resistance force * Max. velocity


I came out with around 50 kw.....but this is the power required by vehicle.

How to calculated the motor power?

I don't think 50 kw powered motor is required to propel a vehicle with gross weight around 700 kg

• Depends on how fast you want to propel the 700kg's. Sep 15 '17 at 19:28
• Also recalculate for the power required to climb a moderately steep hill (say 10 or 12%) at enough speed to avoid getting in the way of traffic. Dec 4 '20 at 19:12
