How to Deal with Electric Vehicle Power Failure?

[ChaseLee]

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.

That time when I was driving my electric car home and suddenly lost power, I was so scared that I quickly coasted to the roadside and turned on the hazard lights. Checking the dashboard, I found a system error message. After waiting a while and restarting, it improved somewhat. Later, at the shop, they found it was a loose wiring issue. Now, I pay attention to any abnormal vibrations or noises while driving, as these can be early warning signs. If a malfunction occurs, after stopping, avoid repeatedly restarting to prevent further damage. Instead, call for roadside assistance or contact the dealership for help. For prevention, I get a full vehicle check-up every six months, maintaining the battery and controller. Electric vehicles are technically complex, and attempting DIY repairs can easily damage more components. Safety first—waiting for professional diagnosis and repair is the wisest choice.

If you encounter power issues with an electric vehicle, the first step is to move the car to a safe location and turn on the hazard lights to prevent other accidents. Then, calmly check if the vehicle can move slowly or restart to see if it's a temporary malfunction. Common causes include software glitches or power supply problems, but avoid dismantling or repairing high-voltage components yourself. Immediately call emergency services or a repair center for assistance, as they can provide remote guidance or on-site handling. Preventing such failures relies on regularly following maintenance schedules and practicing safe driving. Remember not to panic—seeking help is the best strategy.
