Abstract
When operating electricity storage apparatuses in parallel, the degree of degradation of the electricity storage apparatuses is made uniform without using another apparatus or the like. An electricity storage system includes a plurality of electricity storage apparatuses configured to connect to a power grid and supply power to a load and a detector configured to detect a forward power flow from the power grid. The plurality of electricity storage apparatuses includes a plurality of storage cells configured to be charged using electric power supplied by the power grid and a plurality of power controllers configured to control charging and discharging of respective storage cells in the plurality of storage cells. Each of the plurality of power controllers sets a condition for starting discharge of each of the plurality of storage cells on the basis of the state of each of the plurality of storage cells.
