Predicting How Much Range EV Batteries Lose over Time - Autoweek

WebMost electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load. WebFirst, efficiency of an electric motor is just output power divided by input power. Input power is your electrical input power, which is VI. Output power is your mechanical output power, which is speedtorque. Given that, we can see that efficiency for every motor is going to be 0% at no load (i.e., maximum speed at 0 torque).
