Abstract
A battery cellar includes: battery groups each including a plurality of batteries; a power converter (AC/DC converter and DC/DC converter) electrically connected between the plurality of batteries and an electric power system; and a server that controls operation of the power converter in accordance with a DR request from the electric power system, to cause charging and discharging of the plurality of batteries. The battery groups include a low operating group and a high operating group that is less than or equal to the low operating group in terms of the number of types of ranks of batteries included in each battery group, where the ranks each represent a degree of battery degradation. The server suppresses charging and discharging of the plurality of batteries included in the low operating group, relative to charging and discharging of the plurality of batteries included in the high operating group.
