Abstract
A storage battery system relating to the present invention includes first and second PCSes. The first PCS performs charge and discharge to/from a first storage battery. The second PCS performs the charge and the discharge to/from a second storage battery. The second storage battery has a shorter service life than the first storage battery. A controllers controls the first and second PCSes on the basis of a charge/discharge request and storage battery information. The controller includes an SOC correction unit and a charge/discharge command unit. The SOC correction unit calculates SOCs of the first and second storage batteries, corrects the SOC of the second storage battery upwards in the case that the charge/discharge request is a charge request, and corrects the SOC of the second storage battery downwards in the case of a discharge request. The charge/discharge command unit determines charge/discharge commands so as to preferentially perform the charge from the storage battery of a low SOC in the case that the charge/discharge request is the charge request and to preferentially perform the discharge from the storage battery of a high SOC in the case of the discharge request.
