Note:
1. Each battery module has one slave BMS circuitry inside;
2. Master BMS circuitry(we called "BMU") collect all information from each battery module through RS485, then decide to cut-off the contactor or not;
3. We strongly recommend customer to use two contactors (one for charge and another for discharge) in the battery system.
Our advantages
BMS:
O’CELL 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;
1. Modular design makes the system installation, maintenance easier;
2. Battery modules can be connected in series or parallel to make the system more flexible;
3. IP56 dust and water proof design suit for in severe circumstance;
4. Dual LED indicator makes the battery module status easy to know;
