Controller damage generally manifests as weak car starting and difficulty in pushing the car. Below are the specific causes of controller damage: 1. Power device failure: Damage to power devices is usually caused by motor failure; poor quality of the power device itself or insufficient rating; improper installation or vibration loosening; motor overload; damage to the power device drive circuit or unreasonable parameter design. 2. Damage to the internal power supply of the controller: Damage to the internal power supply of the controller is generally caused by a short circuit in the controller's internal circuit; a short circuit in peripheral control components; or a short circuit in external wiring.
