A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and / or balancing it.
Specification:
1. Resistance Inner ≤15 mΩ
2. Self-Consumption Working Current:≤60 uA
3. Sleep Current (when Over-discharge): ≤10 uA
4. Working Temperature Range: -30/+80 ℃
Attention When Connecting:
1. When we connect BMS with cells or disassemble BMS from battery pack, the following order and regulations must be complied with to avoid damage of components of BMS and problems of not protecting of cells.
2. In order to achieve the best performance of BMS and to run the longest distance, all the battery must be matched well (Each battery voltage ≦0.05V, IR≦15 mΩ, capacity≦30mAh) to make sure the better consistency of the battery.
3. Cell must be connected in parallel first, after then connected in series.
Connection:
1. Connect charging /discharging wire, battery pack negative wire
2. After confirm the wires are connected OK, plug the connector cable in the BMS Do not plug connector cable in the BMS before connect wire.
3. Attention, ESD protection during work.
4. Package included: 1 x Lithium Battery Protection Board 1 x 13S Cable
