Abstract:

To make sure the safe and reliable operation of echelon-use battery energy storage system, this paper proposes a safe battery management system for 100 kW·h echelon-use energy storage battery system. Firstly, we analyze the characteristics of 100 kW·h echelon-use power battery for energy storage, including the battery capacity distribution analysis, SOC-OCV characteristics analysis of battery module with different capacities under certain conditions, the charge and discharge capacity test of system, the inconsistency analysis of battery capacity, etc. And the key parameters used in the echelon-use battery manage system have been decided. Then, we analyze the system safety and reliability of echelon-use battery characteristics in order to ensure the safe and reliable operation of echelon-use battery energy storage system, and adopt the system-level fault diagnosis method and multilevel fault alarm strategy. Finally, we use the developed battery management system prototype to test and verify the system capacity. The experimental results show that this battery management system can meet the application requirements of the echelon-use battery energy storage system.
