Troubleshooting and maintenance of charger charging indicator light faults

The troubleshooting and repair of the charger charging indicator light malfunction can be carried out in the following steps:

First, the steps for investigation

Check the power supply and sockets

Confirm that the socket is powered normally: Use other electrical appliances to test if the socket is powered and ensure that the output voltage of the socket meets the requirements of the charger (usually 220V AC).

Check the grounding wire: Ensure that the socket is well grounded to prevent the charger from malfunctioning or the indicator light from malfunctioning due to poor grounding.

Check the charging cable and interface

Confirm that the cable connection is stable: Check whether the charging cable is correctly connected to the charger and the vehicle's charging interface, without any looseness or loose connection.

Check the interface status: Inspect the charging interface for any foreign objects, damage or oxidation. Clean or replace the interface if necessary.

Check the switch of the charging connection device

Confirm the switch status: Check whether the switch of the charging connection device has been accidentally pressed, causing the charging to stop or the indicator light to go out.

Check the status of the power battery

Confirm the battery temperature: If the temperature of the power battery is too high, the charger will automatically stop charging and turn on the fault light. Wait for the battery to cool down before attempting to charge it.

Check the internal components of the charger

Visual inspection: Open the charger casing (operated by a professional) to check if there is any false soldering, detachment or damage to the internal components.

Circuit inspection: Use a multimeter to check whether the internal circuits of the charger are normal, including the power cord, indicator light circuit, fuse, etc.

Check the compatibility of the charging pile with the vehicle

Confirm protocol matching: If a public charging pile is used, check whether the charging protocol of the charging pile matches that of the vehicle.

Try other charging stations: If possible, try using other charging stations to charge your vehicle to rule out the possibility of charging station malfunctions.

Second, maintenance methods

Rewire or replace the socket

If the socket is insufficiently powered or has poor grounding, rewire or replace it with a socket that meets the standards.

Replace the charging cable or interface

If the charging cable or interface is damaged, replace it with a new cable or interface of the same model.

Repair or replace the internal components of the charger

If the internal components of the charger are poorly soldered or damaged, they need to be repaired or replaced by professionals.

Contact professional maintenance personnel

If the above steps fail to solve the problem, it is recommended to contact an authorized car service store or a professional maintenance personnel for a comprehensive inspection and repair.

Replace the battery (if necessary)

If the vehicle battery is damaged and causes a charging failure, a new battery needs to be replaced.
