How far an electric car can run depends on what parameters?

How far an electric vehicle can run depends on its motor power and battery capacity. For example, the motor power is 650W, with a 48V20AH battery, driving at a speed of 35 kilometers per hour, and the theoretical cruising range is about 52.5 kilometers.

The theoretical calculation process is as follows:

1) uniform average current = power/voltage = 650w/48v =13.5a;

2) theoretical driving time = battery capacity/average current = 20ah/13.5a =1.5h;

3) Calculate mileage according to the speed of 35km/h = driving time * speed =1.5h * 35km/h = 52.5km. ..

When the load increases, the output torque and power of the motor increase. The mileage will be less at this time. This is also related to road conditions and ambient temperature. When the road conditions are often creeping wave or starting, the mileage will be shortened, because the current in creeping wave and starting is larger than the average current, so the time will be shortened. The change of ambient temperature will also affect the battery capacity. The higher the temperature, the higher the capacity, and the lower the temperature, the lower the capacity.
