Two battery charging methods at low temperature

　　In the low temperature environment, if the battery is charged, the battery must be restored to the working state of normal temperature. The following two methods can be done.

　　1. Charger heating battery

　　This method is heated by special chargers, because it cannot be charged normally in the low temperature environment. Relying on the charger to heat the battery, increase the temperature to zero -degree above zero, and then charge the battery. This method is a safer and effective method, but the time it takes is relatively long, because the charger in a low temperature environment can only perform small -rate discharge heating. Therefore, it takes about 1 to 3 hours to heat it before charging.

　　2. The protective board self -heated battery

　　The battery of BMS/ PCM can provide two functions. One is low -temperature protection. When the battery discharge is lower than the set value, it will have warnings, or protection functions, and directly disconnect the electricity to prevent the low temperature from being damaged or damaged to the battery. ACCIDENT.

　　The second type is to start the low temperature self -heating function through the protective board. Depending on the environmental temperature, the value can be customized. For example, a 5000mAh battery will reserve 1000mAh power in the battery every time discharge. Before the charge, BMS will release the reserved power to heating the battery until the charging temperature, and the battery will automatically automatically will automatically automatically will automatically automatically. Charging. These are based on BMS settings.
