Claim Text:
1. A battery unit comprising: a battery cell that charges and discharges electric power, the battery cell having a cell main body comprising opposing first and second planar surfaces, and a pair of plane-shaped electrode terminals both about coplanar with the first planar surface of the cell main body; a bracket that has an outer peripheral wall portion surrounding an outer peripheral side surface of the battery cell, and a support body which is provided inside the outer peripheral wall portion and supports the battery cell, the support body comprising (1) a rib portion extending inward from an inner side surface of the outer peripheral wall portion, and (2) a plate-shaped member in which a distribution channel of refrigerant is provided inside thereof, wherein the distribution channel extends parallel to at least one of the first and second planar surfaces of the cell main body, and wherein two battery cells are inserted from a front surface side and a back surface side of the bracket into the outer peripheral wall portion and are mounted on both side surfaces of the support body, a respective pair of electrode terminals of the two battery cells defining a space therebetween, the outer peripheral wall portion of the bracket extending within the space, and the rib portion extending between a pair of the second planar surfaces of the cell main bodies; at least one bus bar coupled to the bracket within the space so as to electrically connect the respective pair of electrode terminals; and a connector coupled to the terminals and including insertion portions for electrically connecting terminals of the same pole in parallel and terminals of different poles in series.
