Abstract

An energy storage device comprises: an energy storage module with a plurality of energy storage cells; and a battery control unit configured to execute a balancing procedure to equalize the states of charge (SOCs) of the energy storage cells. The battery control unit is configured, where a self-discharge rate of the energy storage module per unit time is defined as a unit discharge rate and a time interval until the balancing procedure is next executed is defined as a standby interval, to adjust the standby interval to be shorter when the unit discharge rate is large than when the standby interval is small.
