Cause analysis and troubleshooting: Check whether the charging interface is inserted in place, and whether the vehicle interface is dirty or foreign. Please clean it before charging. Turn off high power applications when using an on-board charger, as system power consumption affects the charging speed. Maintain the proper temperature in the car.

Considering the charging safety, the temperature is too high (greater than 45 degrees) or too low (less than 10 degrees) will affect the charging speed. Charge at a proper temperature. If not, keep giving feedback.
