An energy storage system balancing device arranged to perform balance processing of charge states of a plurality of energy storage systems being disconnected from each other and from external loads is provided. Each of the storage systems is divided into a plurality of cells and at least one equalization device, is arranged, in each storage system for balancing the cells within the system. The balancing device is arranged to at least collect information about voltage of at least one cell in each storage system from the equalization device/-s and determine a balancing status of the storage systems on the basis of the collected information. The balancing device 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 the balancing of the cells. |
