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 battery pack produce by GBP. GBP¡¯s BMS is advanced integration of management, protection, communication and self-diagnose and cell balancing, which is self-technical patent of GBP.
Major functions: Overcharge protection Overdischarge protection Overcurrent protection Overheat protection(NTC) Short circuit protection Temperature sensing Cell monitoring & balancing Communication interface Self-diagnose Power gauge
GBP can design and produce PCM & BMS according to detailed technical parameter of customer¡¯s products
