Abstract

A device for controlling a storage battery system is provided. The device includes: a state information calculator configured to calculate state information on each of batteries of a plurality of storage battery modules; a conversion efficiency characteristics calculator configured to calculate a power conversion efficiency of each of DC/DC converters of the plurality of storage battery modules; and a storage battery module selector configured to select one or a plurality of storage battery modules to be used while the storage battery system is charged or discharged and to determine a charge power or a discharge power of each of the selected storage battery modules, based on the state information of the batteries and the power conversion efficiencies of the DC/DC converters.
