Abstract: The present battery management system for energy storage is similar to that for electric vehicle batteries. It can be applied to small capacity battery systems and has relative simple function and low timeliness. Large capacity cells in series for energy storage needs advanced battery management system with higher efficiency. A three layer management system is presented to attack the problems raised for large energy storage batteries. Hardware and software of bottom layer BMU, middle layer BCMS and top layer BAMS are introduced in detail. The hierarchical system of energy storage battery management has following functions: measurement and calculation, cell balance, high voltage safety management, data statistic and storage, charging and discharging managements, warning and communication.

Key words: energy storage, battery management system, hierarchical
