How to Deal with Electric Vehicle Power Failure?
2 Answers
Electric vehicle power failure causes and solutions are as follows: 1. Fuse blown: Replace the fuse to solve the issue. 2. Power switch damaged: Replace the power switch, professional repair required. 3. Hall throttle damaged: Use a multimeter in DC voltage mode to measure the output voltage of the throttle's green wire. If there is a 1-4.2V output, the throttle is normal; if there is no voltage output, the throttle is burnt out and needs replacement. 4. Controller damaged: Use a multimeter in DC voltage mode to measure the output voltage of the controller's red wire (connected to the throttle wire plug). If there is around 5V output, the controller is normal; if there is no voltage output, the controller is burnt out and needs replacement.
If my electric vehicle experiences a power failure, I will immediately pull over to the side of the road and turn on the hazard lights for safety. Next, I will check the dashboard warning lights, such as low battery charge or motor overheating alerts. I will try turning the vehicle off for a few minutes and then restarting it, as temporary software glitches may resolve themselves. I will also ensure the charging status is normal and, if necessary, use a mobile app to check the fault code records for reference. Never attempt to repair high-voltage components yourself—it's too risky. Instead, call for roadside assistance or contact the brand's service center directly. As a daily habit, it's important to schedule regular maintenance checks for battery health, motor cooling system, and software updates, which can significantly reduce unexpected issues. If problems arise, don’t panic—seeking professional help is always better than random attempts.
