1. Daily inspection

Appearance inspection:

Visually check whether the appearance of the plastic insulating shell of the charging port has been deformed or fallen off by heat melting. If it is severely deformed by heat melting and affects normal use, it needs to be replaced in time.

For charging ports with gold-plated connector pins, it should be bright gold normally; for charging ports with silver-plated connector pins, it should be bright silver normally.

Connector Pinsstatus inspection:

If there is dust or other foreign matter inside the charging port Connector Pins, it cannot be discharged and affects normal use and needs to be replaced.

Visually check whether the reed and bottom of the charging port Connector Pins are yellowed, blackened or broken. If it is slightly yellow, it can continue to be used, but if it is dark yellow or black, it needs to be replaced.

2. Plug and unplug operation specifications

Start charging: Aim the charging gun at the corresponding charging port and push it in.

End charging: First perform necessary operations on the charging device (such as swiping the card or setting to stop charging), then unlock the vehicle, then press the unlock button of the charging gun and hold it for 1~2 seconds before pulling out the gun. Avoid pulling out the charging gun directly or quickly to reduce the risk of Connector Pins wear and arcing.

3. Regular maintenance

Professional inspection: It is recommended that car owners go to the service shop regularly for professional inspection, including the wear of the charging port Connector Pins and whether the connection is reliable.

Cleaning and maintenance: Regularly use soft cloth or hair dryer and other tools to remove dust and debris from the charging port terminal and the surrounding area. Be careful to avoid using sharp objects to scratch the Connector Pins surface.

4. Precautions

Avoid water immersion: Ensure that the charging port will not be soaked in water in rainy and snowy weather to avoid short circuits and other faults.

Standard use: Use charging piles and charging guns that meet national standards for charging, and avoid using non-standard charging equipment to damage the charging port.

Timely maintenance: If the charging port is found to be abnormal or faulty, it should be repaired or replaced in time at the service shop.

In summary, the maintenance of GB/T DC Energy Vehicle Connector Pins requires car owners to pay more attention in daily use, follow standardized operating procedures, and conduct professional inspections and cleaning and maintenance regularly. This is the only way to ensure the normal operation of the charging system and the safety performance of the vehicle.
