Abstract
An electric storage apparatus according to one aspect of an embodiment includes a battery unit, a determination unit, a virtual processing unit, and a connection controlling unit. The battery unit includes storage batteries to be connected in parallel. The determination unit determines, when the battery unit is started up, a startup type indicating a discharge start or a charge start. The virtual processing unit generates connection orders. Each of the connection orders is obtained by virtually and sequentially connecting in parallel storage batteries, of the storage batteries, having potential differences within a predetermined range so as to equalize electric potentials of the storage batteries. The connection controlling unit selects, among from the connection orders, a connection order in which the equalized electric potential is an electric potential according to the startup type determined by the determination unit, so as to connect in parallel the storage batteries.
