Abstract
In a power storage system, a management device calculates a state of power (SOP) of a whole of a plurality of power storage blocks connected in parallel based on an SOP of each of the plurality of power storage blocks. At least one of the plurality of power storage blocks is disconnected from the power storage system, and when at least one switch is turned on to return at least one disconnected power storage block to the power storage system having the parallel-connected power storage blocks, the management device calculates an SOP of a whole of the power storage blocks after a return of the at least one power storage block based on a deviation in current between each of the power storage blocks including the at least one returned power storage block to determine an upper limit level of power or current flowing into a power converter.
