Key points for the detection and maintenance of charger plug wear

The key points for detecting and maintaining the wear of charger plugs are as follows:

Key points of inspection

Visual inspection:

Regularly check the surface of the charger plug for obvious wear, scratches, corrosion or deformation.

Check whether there is rust, oxide layer or coating peeling off on the metal part of the plug.

Contact performance test

Insert the charger plug into the vehicle's charging port and check if it is secure and if there is any looseness or poor contact.

Try using a multimeter to measure the contact resistance between the plug and the interface to determine whether the contact performance is good.

Function verification

Conduct a charging test using a worn plug to observe whether the charging efficiency has decreased and whether there is any abnormal heating or charging interruption during the charging process.

Key points of maintenance

Cleaning treatment:

If there is slight wear or oxide layer on the surface of the plug, you can use fine sandpaper to gently sand the surface of the plug to remove rust and debris.

Wipe the plug with a clean cloth to ensure there is no dust or debris left behind, so as to maintain good contact performance.

Replace parts:

If the metal part of the plug shows severe corrosion, deformation or large-scale peeling of the coating, it is recommended to replace it with a new one.

Choose a new plug with the same specification as the original one to ensure good contact and current transmission.

Preventive measures:

Avoid violent plugging and unplugging of the charger plug to reduce wear and tear between the plug and the interface.

When using the charger in a damp or dusty environment, corresponding protective measures should be taken, such as using a dust cover or waterproof bag.

Regularly inspect and maintain the charger plug to promptly identify and address potential issues.

Professional maintenance

If you do not have the relevant maintenance skills or tools, it is recommended that you send the worn charger plug to a professional repair point for handling.

Professional maintenance personnel can more accurately determine the degree of plug wear and take appropriate repair or replacement measures.
