Reasons for the sudden stop of charging during the use of an electric vehicle charger

If an electric vehicle charger suddenly stops charging during use, it may be caused by the following multiple reasons:

First, the power supply issue

Power system outage

If the power system in the area fails or there is a planned power outage, it will cause the charging to be interrupted. At this point, you need to wait for the power to be restored or go to other service areas with electricity for charging.

Power failure of the charging pile

The power line, socket or internal power module of the charging pile may malfunction, resulting in abnormal power supply. At this point, you can try replacing the charging pile or contact the service area staff for maintenance.

Power overload or tripping:

When multiple charging piles are used simultaneously, it may lead to power overload and cause a tripping phenomenon. At this point, you should wait for a while and then try charging again, or choose another charging station.

Second, issues with charging equipment

Poor contact of the charging cable

Poor connection between the charging cable and the charging interface of the charging pile or electric vehicle may cause charging interruption. At this point, it is necessary to check whether the cable connection is firm and ensure there is no loose connection.

Charging pile malfunction

The charging pile itself may malfunction, such as display screen failure or communication failure, which can prevent normal charging. At this point, you should contact the service area staff for inspection or replacement of the charging pile.

Overheating of the charging equipment

Long-term high-load operation may cause the charging equipment to overheat, triggering the thermal protection mechanism and automatically stopping charging. At this point, you should wait for the device to cool down before attempting to charge it again.

Third, the issue of electric vehicles

Battery Management System (BMS) failure:

The battery management system of electric vehicles is responsible for monitoring and controlling various functions of the battery. If a malfunction occurs, it may cause the charging to be interrupted. At this point, it is necessary to contact the car manufacturer or professional maintenance personnel for inspection and repair.

Battery overheating

When charged in a high-temperature environment or under high load for a long time, the battery may overheat, triggering the thermal protection mechanism and automatically stopping charging. At this point, you should wait for the battery to cool down before attempting to charge again, and consider reducing the vehicle load or improving the charging environment before charging.

The battery is fully charged.

If the battery of an electric vehicle is fully charged, charging will automatically stop. At this point, there is no need to worry. You can drive the vehicle normally.

Vehicle fuse damage:

If the fuse of an electric vehicle is damaged, it may cause the charging circuit to be interrupted. At this point, you should contact the car manufacturer or a professional maintenance personnel for inspection and replacement of the fuse.

Fourth, human factors

Accidentally touching the emergency button of the charging pile:

Some charging piles are equipped with emergency buttons. If you accidentally touch this button, it will cause the charging to be interrupted. At this point, you can try restarting the emergency button to restore charging.

The switch of the charging connection device was accidentally touched:

In some cases, the switch of the charging connection device may be accidentally touched, causing the charging to be interrupted. At this point, the charging device should be reconnected and the charging process initiated.

Fifth, environmental factors

Extreme temperature

In extremely low or high temperature environments, the working efficiency of the battery may be limited, leading to charging interruption. At this point, you should wait for the ambient temperature to be suitable before attempting to charge again, or preheat or cool the battery before charging.

Damaged charging facilities:

Charging facilities may fail to function properly due to long-term use or damage from external forces. At this point, you should contact the service area staff for inspection or replacement of the charging facilities.

Solve the suggestion

Check the power supply and charging equipment:

First, check whether the power cord and socket are properly connected to ensure that the charging pile and charging cable are undamaged.

Check the vehicle status:

Check the battery management system, battery temperature and power status of the electric vehicle to ensure that the vehicle has no faults.

Contact professionals:

If the problem cannot be determined or the above methods still fail to solve it, you should contact the manufacturer of the electric vehicle, professional maintenance personnel or service area staff for assistance.

Replace the charging pile or charging station:

If the current charging pile is not functioning properly, you can try replacing it with another one or go to another charging station for charging.

In summary, the sudden cessation of charging by an electric vehicle charger during use may be caused by a variety of reasons. When encountering such problems, one should remain calm, investigate the possible causes one by one, and take corresponding solutions.
