<p>PROBLEM TO BE SOLVED: To obtain a storage battery system that is able to satisfy both a demand from a host controller 16 that a plurality of battery packs 1 are charge/discharge-controlled not separately but in an integrated manner as one storage battery group, and a demand from the battery packs 1, which is contrary to the former demand that each of the battery packs 1 is carefully charge/discharge-controlled.SOLUTION: The host controller 16 supplies a first charge/discharge limit value L1 to a master storage battery management unit 15a based on battery pack information and the entire charge/discharge plan. The master storage battery management unit 15a supplies second charge/discharge limit values L21 to L2N to a storage battery management functional part of each of the battery packs 1 based on the first charge/discharge limit value L1. The storage battery management functional part supplies third charge/discharge limit values L31 to L3N to a bidirectional power circuit 12 based on malfunction information or charged state of a storage battery 2 in each of the battery packs 1.</p> |
