Why does the gun jump when the energy vehicle is charging?

1. There is a problem with the communication module between the vehicle's BMS (charging management system) and the charging pile, causing the wrong command surface to jump the gun

2. The charging pile system has a self-protection system. When the screen displays corresponding fault codes such as insulator detection fault, DC output short circuit, etc., it is first necessary to check whether there is any abnormality in the vehicle charging port or charging grab.

3. The vehicle charging port is worn out due to frequent plugging and unplugging. When the wear is serious, the gun will jump out.

4. The charging gun is equipped with a charging thermal protection device. In summer, when electric vehicles are driven for a long time and the battery temperature is too high, the charging temperature rises to the warning value and the system will automatically stop charging, causing the gun to jump.

5. When starting the power supply during charging, the vehicle will cut off the power for self-protection. If the gun jumps frequently during charging, it is recommended to contact the charging station and vehicle after-sales service.
