Can Changing the Controller Increase the Vehicle Speed?
1 Answers
Replacing the controller cannot increase the speed of an electric vehicle. To boost the speed, you would need to add more batteries or switch to a high-speed motor. Electric vehicles generally have good acceleration from a standstill but their top speed is not very high, and increasing the speed can be quite complicated. Here are some relevant details: Suggestion: For new national standard electric bicycles, it is not recommended to increase the speed. The reason is that modifying or replacing the controller can be detrimental to the vehicle, and low-quality controllers may accelerate vehicle wear and tear. Consequences: Additionally, new national standard electric bicycles have a speed limit of 25 km/h, which is based on safety considerations regarding the vehicle's structural strength and brake wear. Deliberately increasing the speed may reduce the structural safety strength of the vehicle, potentially leading to accidents during operation. Replacing the Motor: The motor is designed based on the voltage-to-speed ratio, not the current ratio. If the controller matched with the electric vehicle is sufficiently large, the power output will not increase. Therefore, to increase the speed, you can either raise the voltage or replace the motor with one that has a higher speed-to-voltage ratio.
