How to solve the problem of charging interruption in electric vehicle chargers

To solve the problem of charging interruption in electric vehicle chargers, the following aspects can be considered for investigation and resolution:

First, physical connection check

Check the charging gun and interface: If the charging gun is not properly inserted or the interface is dirty, it may cause poor contact, triggering the protection mechanism of the charging pile and interrupting charging. Make sure the charging gun is plugged in tightly and the interface is clean and undamaged.

Confirm the connection of the AC charging equipment: Incorrect connection of the AC charging connection equipment may cause charging interruption. It is necessary to confirm that the switch of the AC charging equipment has popped up. Pay attention to the different plug lengths and connection positions of the seven-core to seven-core cable charging equipment.

Check the charging connection device cable: Poor connection of the charging cable can cause charging interruption. It is necessary to confirm that the charging connection device cable is not wrongly connected.

Second, battery status check

Battery temperature management

When the temperature of the power battery is below -20℃ or above 65℃, charging will automatically stop. The vehicle should be placed in an environment with a suitable temperature and charged only after the temperature returns to normal.

When the temperature of the power battery exceeds the limit, the combination instrument will display the over-temperature alarm indicator light of the power battery, and the charging will automatically stop. It is necessary to wait for the battery to cool down before charging.

Battery health status: Battery malfunctions such as overheating, overcooling, and battery capacity attenuation may cause charging interruptions. If the battery malfunctions, the vehicle needs to be sent to a 4S store for inspection and repair by professionals.

Third, inspection of charging equipment

Check the charging piles:

If the charging pile or vehicle shows a fault, make sure there is a power system fault light on the combination instrument, or a charging system fault prompt, or the charging pile is faulty. It is necessary to carry out vehicle maintenance in a timely manner or contact the charging pile maintenance personnel.

Internal faults of the charging pile may cause unstable output and trigger the protection mechanism. You can try replacing the charging pile.

Check the charger:

Malfunctions of charging equipment, such as faults or damages to charging piles or cables, can prevent normal current transmission, leading to charging interruptions. It is necessary to check if there are any obvious damages to the charging equipment, such as damaged cables or loose connectors. If so, replace them in a timely manner.

Problems with the charger itself may result in the inability to provide stable power, causing the charging process to be intermittent. If the charger malfunctions, a charger compatible with the new energy vehicle needs to be replaced.

Fourth, power supply and environmental inspection

Check the charging power supply: If the grid voltage of the charging power supply is unstable or the socket contact is poor, it may cause the power to be unable to be transmitted normally, resulting in charging interruption. It is necessary to check whether the power cord and socket are properly connected, or try to replace the power socket.

Avoid extreme environments: Extreme weather conditions such as thunderstorms and high temperatures may affect the normal operation of charging equipment. Charging should be avoided in extreme temperatures.

Fifth, software and Settings check

Check the charging strategy Settings: Some electric vehicles may be equipped with charging strategy Settings, such as setting to stop charging at a specific level or at a specific time to protect battery life or meet user needs, etc. It is necessary to check the vehicle-end Settings.

Update software or firmware: Issues with the software or firmware of the vehicle or charging pile may cause abnormal charging. It is necessary to update the software or firmware in a timely manner.
