Abstract
A managing device calculates a whole state of power (SOP) that is an SOP of a whole of the plurality of power storage blocks based on SOPs of the respective power storage blocks and currents flowing through the respective power storage blocks, and sets an upper limit value of power or a current for at least one of charging and discharging by a power converter, based on the whole SOP thus calculated. The managing device estimates a current flowing through each of the power storage blocks from a voltage and an internal resistances of each of the power storage blocks before the power converter starts power conversion.
