How to know in advance if an Used Electric Car has a fault?
In fact, every time before or during operation, you must ensure observation, testing, and listening. Observation means carefully observing whether every important component on the car is damaged. Testing means completing multiple test starts to detect whether the car's control system is normal. Then listen. Of course, it means carefully monitoring whether there are abnormal sounds when the vehicle is started or running. For example, if the noise is too loud, it can be judged whether the motor and rear axle are in good condition.
