3. 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;
