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;
