Abstract
A power storage system comprises the following: a battery unit in which a plurality of battery cells are connected; an acquisition unit for continuously acquiring, while the battery unit is discharging, (V) which represents the extent of the discharge from the battery unit and the temperature (T) of the battery unit when the degree of discharge is (V); a balancing unit for executing cell balancing by which a difference in amount of charging between battery cells is reduced; and a balancing control unit for controlling the balancing unit so that when a reference state is detected based on (V) and (T), cell balancing is not executed, in accordance with a result of the detected reference state.
