Why does the electric vehicle suddenly stop moving while the power is still on?

This situation occurs due to a damaged controller, and replacing it will resolve the issue. Below are specific details about the controller: 1. Introduction: The electric vehicle controller is a core control unit of the vehicle. It features functions such as reverse charging, stall protection, dynamic and static phase loss protection, cruise alarm, high-speed control, mode switching, and follow-up ABS system. 2. Technology: In the traditional development process of control units, a serial development model is typically adopted. This involves first defining system requirements and corresponding functions based on application needs, followed by hardware design. Assembly language or C language is then used to write hardware-oriented code, after which software-hardware and external interface integration is completed, and finally, the system undergoes testing and calibration.
