Why does an electric car suddenly stop moving while driving?
2 Answers
An electric car suddenly stopping while driving is usually due to battery failure, which could be caused by a dead battery or battery malfunction. Extended information: Precautions for automotive battery maintenance: Pay attention to the battery storage environment: The storage environment of the battery should not be neglected. Even if the car is not used for a long time, it should be charged once a month to prevent the battery from being in a depleted state. Of course, it is also necessary to avoid exposing the battery to direct sunlight, otherwise the plates will age and the battery will fail. Regularly check the battery: Regularly checking the car battery is also very important, otherwise battery damage will directly cause the car to fail to start normally.
I've been driving electric vehicles for over a decade and encountered this situation quite often. It's usually caused by suddenly low battery level or when the battery management system detects an issue and activates protection mode to force shutdown. Another possibility is a malfunction in the motor controller cutting off power output. Once on the highway, my system automatically shut down, which was quite startling – later found out the charging port wasn't securely connected. My advice is to pull over immediately, try restarting the system. If that doesn't work, don't tamper with it and promptly contact a service center or use roadside assistance – safety comes first. Regular battery maintenance is crucial, including periodic checks on charge/discharge status. Avoid waiting until the battery is nearly depleted before recharging, as this preventive measure can prevent many such issues.
