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;
