1, reason: the temperature is too low;
Solution: The vehicle is parked in a slightly higher temperature place for charging.
The battery is not active in winter, and it will be difficult to charge. At this time, the electric vehicle can be parked in a relatively high temperature place for a period of time to charge.
2, cause: battery life end;
