Beschreibung
Zusammenfassung:	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, the power converter being capable of bidirectional power conversion; 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 a plurality of batteries. The server suppresses charging and discharging of batteries of a rank representing a smaller degree of battery degradation, relative to charging and discharging of batteries of a rank representing a greater degree of battery degradation. Proper inventory of batteries of a higher rank can thus be ensured.
