What's the matter with the whole car losing power?

[StCollin]

The reason for the whole car losing power may be caused by battery failure, motor failure, controller failure or brake power failure. Battery failure: loose battery wires, oxidation and poor connection; damaged battery, too low voltage, insufficient power; power switch problems, such as air switch tripping, ignition lock failure, fuse issues, etc. Motor failure: Hall element damage or motor bearing damage, generally manifested as the electric vehicle not moving, weak start, shaking, loud noise, and only moving when pushed by foot. Controller failure: if there is resistance when pushing the motor, and the resistance disappears after disconnecting from the controller, it can basically be judged that the controller is damaged. Brake power failure: damaged brake power switch, the car not moving when the brake is not returned, or open circuit in the brake power line.
