Abstract
An electric storage apparatus according to one exemplary aspect of an embodiment of the disclosure includes a battery unit, a determination unit, and a connection controlling unit. In the battery unit, a plurality of storage batteries is connected in parallel. Each of the storage batteries includes serially connected electric storage elements.
Claims7
An electric storage apparatus comprising:
- a battery unit in which a plurality of storage batteries are configured to be connected in parallel, each of the plurality of storage batteries including serially connected electric storage elements;
- a determination unit that determines, based on electric potentials of the plurality of storage batteries and the electric storage elements;
- (i) whether or not one or more storage batteries to be discharged by connecting in parallel the plurality of storage batteries include one or more electric storage elements, of the electric storage elements, to be over-discharged, and
- (ii) whether or not one or more storage batteries to be charged by connecting in parallel the plurality of storage batteries include one or more electric storage elements, of the electric storage elements, to be over-charged;
- and
- a connection controlling unit that excludes, from target storage batteries to be equalized, (i) the one or more storage batteries to be discharged, which are determined by the determination unit to include the one or more electric storage elements to be over-discharged and (ii) the one or more storage batteries to be charged, which are determined by the determination unit to include the one or more electric storage elements to be over-charged, when connecting in parallel the plurality of storage batteries in a non-charge/discharge period of the battery unit to equalize the electric potentials of the plurality of storage batteries.

An electric-storage controlling method to be executed by a computer, the method comprising:
- while a plurality of storage batteries are configured to be connected in parallel in a battery unit, and each of the plurality of storage batteries includes serially connected electric storage elements;
- determining, based on electric potentials of the plurality of storage batteries and the electric storage elements;
- (i) whether or not one or more storage batteries to be discharged by connecting in parallel the plurality of storage batteries include one or more electric storage elements, of the electric storage elements, to be over-discharged, and
- (ii) whether or not one or more storage batteries to be charged by connecting in parallel the plurality of storage batteries include one or more electric storage elements, of the electric storage elements, to be over-charged;
- and
- excluding, from target storage batteries to be equalized, (i) the one or more storage batteries to be discharged, which are determined in the determining, to include the one or more electric storage elements to be over-discharged and (ii) the one or more storage batteries to be charged, which are determined in the determining to include the one or more electric storage elements to be over-charged, when connecting in parallel the plurality of storage batteries in a non-charge/discharge period of the battery unit to equalize the electric potentials of the plurality of storage batteries.
