1. Check the power supply and connection: Confirm that the charging device is correctly connected to the charging interface of the new energy vehicle. Check if the power plug is securely plugged into the power outlet and if the power outlet has electricity.
2. Check the fan control system: The charging system of new energy vehicles is usually equipped with a fan to dissipate heat. Check if the fan control module or related sensors are working properly. Using the onboard diagnostic system to check for relevant fault codes can help locate the problem.
3. Contact professional maintenance personnel: If the above checks are normal but the fan still does not turn, it may be a fault in the fan itself or a deeper system problem. It is recommended to contact the authorized repair center or professional electric vehicle repair shop of the car brand for further inspection and repair.
