When the battery system detects that the external charging power supply is connected, the system will automatically evaluate whether the battery temperature is within the charging temperature range of the battery. If the battery temperature is lower than 0 ℃, the battery system will automatically enter the heating mode. When the charging temperature is higher than 0 ℃, the system will automatically enter the charging mode
