摘要： The present invention relates to an energy storage system (10) balancing device (16) arranged to perform balance processing of charge states of a plurality of energy storage systems (10) being disconnected from each other and from external loads (14). Each of said storage systems (10) is divided into a plurality of cells and at least one equalization device is arranged in each storage system (10) for balancing the cells within said system. Said balancing device (16) is arranged to at least collect information about voltage of at least one cell in each storage system (10) from the equalization device/-s and determining a balancing status of the storage systems (10) on the basis of the collected information. Said balancing device (16) is further arranged to determine a target cell voltage in dependency of the balancing status and provide the target voltage to each equalization device to control said balancing of the cells.
