Why doesn't the electric car move after braking when power is applied?
1 Answers
Here are the reasons why an electric car doesn't move after braking when power is applied: Damaged electronic components: The Hall sensor inside the accelerator (throttle) is damaged. The accelerator is crucial for electric cars, and the Hall sensor is vital for the accelerator. Therefore, damage to the Hall sensor will directly cause the vehicle to have no response when stepping on the accelerator, even if there is power. To check if the Hall sensor is damaged, you can start from the sensor's rated voltage and current, verifying whether these two factors are within the specified range. Values greater or smaller than this range will cause the Hall sensor to malfunction. Brake system failure: The brake power-off system is stuck or not reset, causing the brake system to keep working. In this case, the accelerator may appear "unresponsive." Alternatively, the control circuit may be open, or the controller may have a fault. The controller starts working after receiving the signal from the accelerator. If the controller is short-circuited or faulty, the accelerator naturally won't respond. Motor failure: Motor failure directly causes the vehicle to stop working, and stepping on the accelerator is useless. Identifying motor failure is simple. When the motor fails, it is usually accompanied by smoke, sparks, overheating, etc. Observing any of these signs indicates motor failure. In this case, you should take the car to a repair shop for servicing.
