During the daily charging process, the charging progress bar is suddenly interrupted, and the power is stuck at 90%, or cuts out entirely. Many owners of NEVs (new energy vehicles) have encountered such troubles when charging.
This phenomenon is commonly known as "jumping gun", which means that the charging gun suddenly stops supplying power and disconnects during charging. It will not only disrupt the car use plan but also hint at hidden safety risks. So, what exactly causes abrupt charging interruption? And how to handle them fast?
Here are common reasons and solutions from Maruikel:
msgid "Poor contact between charger and vehicle port"
msgstr "充电器与车辆端口接触不良"
Cause: Loose plug, oxidized ports, dirt, or worn metal contacts create excess resistance, triggering the charger's safety shutoff.
Solution: Desconecte y vuelva a insertar el cargador firmemente. Limpie los puertos con alcohol anhidro, verifique si hay contactos doblados.
Abnormal temperature (overheat protection)
Cause: 高电流、通风不良或极端高温导致枪/电缆过热,激活安全保护装置。
Solution: Pausar la carga y reiniciar después de enfriar. Evitar cargar en un entorno de alta temperatura y verificar si la disipación de calor del equipo de carga es normal.
Charger malfunctions or compatibility issues
Cause: Unstable output, mismatched communication protocols, outdated software, or hardware faults (e.g., broken relays).

msgid "Solution: Try a different charger to test. Contact the operator for software updates or repairs."
msgstr "解决方案:尝试使用不同的充电器进行测试。联系运营商进行软件更新或维修。"
```
"Jumping the gun" no siempre es culpa del cargador, también puede ser un problema con el coche. Pero puedes minimizar los problemas causados por humanos eligiendo cargadores de buena reputación, seleccionando entornos adecuados y siguiendo los pasos correctos.
- ```
Turn off your vehicle first.
```
- Check the charger/port for damage.
- Insert the gun firmly into the car’s port until you hear a "click" (lock confirmation). If no click, reinsert.
- Use the app to start charging after securing the gun.
If it still fails, try another charger or contact the station manager immediately.
