Why doesn't the electric car move after braking and applying power?

[RachelFitz]

Here are the reasons why an electric car doesn't move after braking and applying power: 1. 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, so damage to the Hall sensor will directly cause the vehicle to have no response when pressing the throttle even if there is power. To check if the Hall sensor is damaged, you can examine its rated voltage and current to see if they are within the specified range. Values above or below this range will cause the Hall sensor to malfunction. 2. Brake system failure: The brake power-off system is stuck or not reset, causing the brake system to remain engaged. In this case, the throttle may show "no response." Alternatively, there might be a broken control circuit or a faulty controller. The controller starts working after receiving the signal from the throttle. If the controller is short-circuited or faulty, the throttle naturally won't respond. 3. Motor failure: A motor failure will directly prevent the vehicle from operating, making the throttle useless. Identifying a motor failure is simple, as it is usually accompanied by smoke, sparks, or excessive temperature. Observing any of these signs indicates a motor failure. In such cases, it's necessary to visit a repair shop for maintenance.
