BMS ( Battery Management System )

BMS is higher level PCM, which is safety control and management system to monitor battery status in order to make battery better working and lengthen battery life time objectively. BMS is mainly used in high capacity li-ion/li-polymer/lifepo4 battery packs. BMS is advanced integration of management, protection, communication and self-diagnose and cell balancing.
Major functions:

1.     Overcharge protection

2.     Overdischarge protection

3.     Overcurrent protection

4.     Overheat protection(NTC)

5.     Short circuit protection

6.     Temperature sensing

7.     Cell monitoring & balancing

8.     Communication interface

9.     Self-diagnose

10.   Power gauge
