Claim Text:
1. A battery control device that is used for a battery module including M cells, where M is a positive number, the battery control device comprising: a plurality of integrated circuits that are each provided in correspondence to each of a plurality of cell groups, the M cells being divided into the plurality of cell groups each including N cells, where N is a positive number, that are electrically connected in series, where N<M, and the M cells being electrically connected in series or in series-parallel; and a connector configured to electrically connect the M cells and the plurality of integrated circuits, wherein: the plurality of integrated circuits each include a VCC terminal electrically connected to a positive electrode side of a highest potential cell of a corresponding cell group and a GND terminal electrically connected to a negative electrode side of a lowest potential cell of a corresponding cell group; the VCC terminal and the GND terminal of each integrated circuit are electrically connected with each other via a first path including a capacitor; the GND terminal of a first integrated circuit corresponding to a higher potential order cell group and the VCC terminal of a second integrated circuit corresponding to a lower potential order cell group are electrically connected with each other via a second path between the first and second integrated circuits corresponding to the cell groups electrically connected in series; and and the second path is formed via the connector through the outside of the battery control device when the plurality of integrated circuits and the M cells are electrically connected by the connector.
