5. BMS:

Our BMS consists of Master BMS Circuitry (we named “BMU”), Slave BMS Circuitry (we integrate it into our battery module) and contactor. 

Besides the basic functions such as over charge/ discharge, over current, short circuit, over temperature and balancing, Our BMS owns the following features, 

1). Master-Slave architecture makes the system flexible;

2). Two level warning makes maintenance easier;

3). CAN2.0 and industrial level electronic components make system reliable;

4). Contactor makes high rate charge & discharge feasible;

5). Periodic insulation measurement makes personnel safety possible;

6). Host can control the system easily;
