PROBLEM TO BE SOLVED: To provide a device for controlling battery packs, capable of accurately controlling charging or discharging. SOLUTION: The device includes: a full charge capacity detection means 31 for detecting a full charge capacity of each electric cell with respect to a battery pack 2 in which multiple electric cells 2a and 2b as secondary batteries are connected together; a selection means 32 for selecting a specific electric cell from among the electric cells, based on the full charge capacity of each electric cell; a first internal state decision means 33 for computing the internal state characteristic of the specific electric cell, based on the full charge capacity of the specific electric cell and determining the internal state characteristic of the specific electric cell as the internal state characteristic of the battery pack; and a computing means 36 for computing electric energy that is input or output to or from the battery pack, based on the internal state characteristic of the battery pack.
