lifepo4 battery Lithium ion 48V100Ah for EV electronic car, 48V lithium ion battery

High drain up to 150A(30S);
Humanized monitor interface available;
Easy to install, expand,control and maintenance;

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;

5. High accuracy SOC calculation;

Note:

1. Each battery module has one slave BMS circuitry inside;

2. Master BMS circuitry(we named 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.

4. We can connect more battery modules in parallel to expand the system capacity
