When the electric vehicle does not respond to charging and the lights do not light up, the following steps can be taken to troubleshoot and solve the problem:
1. Check the charger: Confirm if the charger is working properly. You can try using other similar and functional chargers to charge the electric vehicle and observe if there is a response and if the indicator light is on. If the problem is solved after replacing the charger, it indicates that the original charger has a fault and needs to be replaced with a new charger. Check if the interface between the charger and the electric vehicle is compatible to avoid charging failure due to mismatch.
2. Check the battery: If the battery level is too low or the battery has aged, it may also cause unresponsive charging. You can try removing the battery and using tools such as a multimeter to check the battery voltage, to determine whether the battery still has enough power or has reached its service life. If the battery is depleted, you can try using a professional charger to activate charging; If the battery has aged, a new battery needs to be replaced.
3. Check the charging interface and circuit: Check whether the charging interface of the electric vehicle is clean, free of foreign objects blocking, and ensure that the interface is not loose or damaged. If there is a problem with the interface, it should be cleaned or replaced. Check if the charging circuit is intact, without any damage or breakage. If there is a problem with the circuit, it should be repaired or replaced in a timely manner.
4. Seek professional repair: If none of the above steps solve the problem, it may be due to a malfunction in the controller or other internal components of the electric vehicle. At this point, it is recommended to contact professional electric vehicle maintenance personnel for inspection and repair.
By following the above steps, you can gradually troubleshoot and solve the problem of electric vehicles charging without response and the lights not turning on. If the problem is complex or cannot be solved by oneself, professional help should be sought in a timely manner.
