What are the reasons for an electric vehicle suddenly not moving?
2 Answers
Possible reasons for an electric vehicle suddenly not moving are as follows: Controller damage: If the controller of the electric vehicle is damaged, it may cause the wheels to stop turning even when there is power. Solution: Check if there is a burnt smell from the controller. If it is indeed damaged, a new controller needs to be replaced. Motor failure: If the motor of the electric vehicle malfunctions, such as poor contact of the motor carbon brushes, it can also cause the vehicle to have power but not move. Additionally, motor wear and damage can lead to the same issue. Solution: Repair the motor or replace it with a new one.
I've been driving an electric vehicle for several years and have also experienced sudden stops. That time on the highway, the dashboard displayed a battery system malfunction, which really scared me. Common causes include automatic protection due to low battery charge or overheating, motor controller failure, high-voltage circuit short circuits, and sometimes system lockouts due to software update errors. In winter, it's particularly easy for battery performance to degrade due to low temperatures, resulting in reduced range. When this happens, I immediately pull over, turn on the hazard lights, and then try to reboot the entire vehicle system; if that doesn't work, I call for a tow truck. Regular maintenance is crucial—monthly checks on battery health and software update settings can help prevent problems in advance.
