PROBLEM TO BE SOLVED: To provide a storage battery device by which, when charging a storage battery with power from wiring and supplying power of the storage battery to a load part, another load part connected to the wiring can be prevented from dealing with occurrence of an induction failure caused by fluctuation of power consumption in the load part, and a control method.SOLUTION: A storage battery device includes a plurality of storage batteries, a switch part, a charging part and a control part. The plurality of storage batteries are connected in series between a first system connected to the wiring and a second system connected to the load part. The switch part is provided for each storage battery and capable of connecting the storage battery either to the first system or to the second system. The charging part is provided for each storage battery and in the case where the storage battery is connected to the first system, the storage battery is charged with power from the wiring. The control part controls the switch part in such a manner that at least one of the plurality of storage batteries is connected to the second system and a storage battery of which the charging voltage does not meet a predetermined condition, among the storage batteries excluding the at least one storage battery is connected to the first system. |
