What is the reason why an electric car doesn't move after braking and applying power?

The reason why an electric car doesn't move after braking and applying power may be due to damage to the Hall element inside the accelerator (throttle), failure of the braking power-off system, control circuit failure, motor failure, etc. Here is a detailed introduction about braking: Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of a running locomotive, vehicle, other means of transport, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. Brake pads: Automobile brake pads, also called automobile brake linings, refer to the friction materials fixed on the brake drum or brake disc rotating with the wheel. The friction linings and friction blocks inside bear external pressure and generate friction to achieve vehicle deceleration.
The electric vehicle charges after braking but does not move, which may be due to a stuck brake switch. After braking, the system should automatically release to allow the vehicle to move, but if the switch is damaged or stuck, the signal won't reach the controller, and the vehicle naturally won't move. Another possibility is a faulty brake sensor, where the electric vehicle's system thinks it's still braking, triggering the safety protection to prevent movement. Another common cause is a controller issue, which manages the coordination between the motor and brakes. If internal components fail, causing input and output signal confusion, the vehicle will remain stationary. Loose or aged battery connections can also lead to unstable power supply, especially when the battery is in poor condition during charging. Checking whether the brake wire plug is corroded or disconnected is crucial, as many vehicles experience issues due to poor wiring contact. It's recommended to first try pushing and rocking the vehicle to release the brake lock. If that doesn't work, visit a professional shop for inspection—don't ignore this small issue, as it could escalate into a major fault.
