Temperature is greater than -30℃ (allowed to open the heating film the lowest temperature)

Satisfy the above two conditions to start heating

 

Heating closing condition

Stop heating if the temperature is greater than the ending temperature of heating;

The discharge state stops heating;

Under low temperature protection, stop heating after heating for more than one hour.
 

5. Protective circuit specification

The batteries are supplied with a LiFePO4 Battery Management System (BMS)that can monitor and optimized each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge, short circuit. Overall, the BMS helps to ensure safe and accurate running.
