Abstract: An assembled battery reusing system for reusing an assembled battery including a plurality of single cells is provided. The rebuild candidate determining unit (430) determines based on the information about the assembled battery whether a retrieved assembled battery is a rebuild candidate, and the information is acquired by the assembled battery information acquisition unit (i.e. communication unit) (420). The single cell amount determining unit (440) determines an amount of rebuilding-usable single cells included in the rebuild-candidate assembled battery determined by the rebuild candidate determining unit (430). The assembled battery demand information acquisition unit (460) acquires an amount of rebuilding-required single cells required to rebuild a required new assembled battery.

Abstract: Provided is a method of reusing a battery, a battery management system, a battery management apparatus, and an information communication terminal apparatus, wherein, upon retrieving batteries mounted on vehicles, methods of handling the retrieved batteries can be determined at low cost. Measurement data of each of a plurality of stacks constituting a battery pack are transmitted to a data station. The data station stores the received measurement data in a history information storage unit as history information. When history information of a battery pack mounted on a scrapped vehicle is not stored in the history information storage unit of the data station, that battery pack is subjected to recycle processing. When history information thereof is stored in the history information storage unit of the data station, a method of reusing the battery pack is determined on the basis of the history information.
