Where is the power size of electric cars?My family now has two electric cars, one is round, written instructions on battery 48V, the motor rated power is less than or equal to 800W. the car quickly, the table top speed is 60 km. Buy second-hand car is another car, motor for a 800W, the battery is 48V. But the difference between the two vehicle speed is high, climbing difference is also large. I wonder if the motor is not 800W, I hope you say how you look at it, the power motor thanks.
Use a caliper meter to measure the current in the full power work of the electric motor car. This current is multiplied by A by 48V. If it is between 750-850W, the motor is 800W, and on the contrary, it is not!
If the controller can not meet the power of 800W, then it is useless to change the motor only
First, make sure that your electric vehicle controller matches, with unlimited speed and current limiting devices
