Energy storage system function :
1) Balance function; Protect the cells from the imbalance and maintain the capacity of the battery cell to extend the life cycle.
2) Voltage detection of the cells; Provide the accurate voltage measurement of overcharging and discharging, at the same time, offer the reliable data for the equilibrium control strategy.
3) The multi point temperature collection of the singe module; Provide the same number of collection point as voltage, and strictly monitor the temperature to extend the life cycle.
4) Estimate the distributed SOC of every single battery pack series; Power control to every single battery pack series, and improve the capacity and life cycle of the module.
5) Precise current detection; Provide precise data for SOC estimation, meanwhile protect the battery from over current to avoid the damage.
6) Strong extendibility of the three-layer modular structure; response flexibly to the needs of voltage and capacity of different battery pack series
7) The system adopts the CAN2.0 high-speed bus data transmission to ensure the data and information feedback efficiently and timely
8)Provide various high-speed communications interface to connect the peripheral equipment include the Ethernet, RS485,CAN,RS232 and so on
