○ Energy Storage BMS
01
The energy storage lithium battery system should have a battery management system (BMS). The BMS is designed in accordance with GB/T34131-2017 to realize the overall control and protection of the energy storage battery stack and realize communication with PCS and EMS.
02
The BMS should realize the acquisition of high-precision and high-reliability battery cell voltage and temperature, and at the same time perform high-precision estimation of the state of charge (SOC) of the battery energy storage device, and realize the power balance between battery cells through the balance control circuit. In the event of abnormal battery data, a fault alarm and protection are triggered.
03
The topology configuration of the BMS should match and coordinate with the topology of the PCS and the grouping of batteries, and optimize the control and overall management of the battery operating status. The specific implementation level of each function in the BMS functional requirements is determined by the topology configuration of the BMS, and it should be implemented layered and local. The slave control BMU is responsible for the collection of battery voltage and temperature.
