A first heat conductive layer that contacts a battery cell and has a first thickness is provided on the sandwiched portion of each heat transfer plate. A second heat conductive layer is provided on the facing surface of each heat transfer plate other than the heat transfer plate that is the closest to the joint body when the joined portion is joined to the joint body. The second heat conductive layer is configured to contact the joint body. The second heat conductive layer on the heat transfer plate that is the farthest from the joint body when the joined portion is joined to the joint body has a second thickness, which is greater than the first thickness.

Abstract: A battery module has aligned battery cells, two plate members provided on the opposite ends in the aligning direction of the battery cells, fasteners joined to the plate members to integrate the battery cells, at least one connection bus bar, which connects terminals of adjacent battery cells in the aligning direction, and an elastic member, which absorbs expansion of the battery cells in the aligning direction. Each connection bus bar includes two connection portions connected to the terminals and a bend portion located between the two connection portions. In response to expansion in the aligning direction of the battery cells, the bend portion is extendable in the aligning direction. A total allowed deformation amount, which is based on the allowed deformation amount of the bend portions in the aligning direction, is set to be greater than or equal to the thickness in the aligning direction of the elastic member.

The battery cell is accommodated inside of the case. The sealing material is arranged between the lid member and the through-hole peripheral part so as to ensure the air-tightness of the case. The spacer is arranged between the lid member and the through-hole peripheral part so as to maintain the interval between the lid member and the through-hole peripheral part.

Abstract: A battery pack has a sealed case. Battery modules are accommodated in the sealed case. An opening in the main body is closed by a rectangular plate-shaped lid member. The lid member has a releasing portion and a joint portion. When the internal pressure of the sealed case increases, the lid member is deformed away from an opening edge of the opening. This discharges gas from the sealed case through the releasing portion. In addition, the joint between the joint portion and the opening edge is maintained even when the internal pressure of the sealed case increases, deforming the releasing portion, and the gas inside the sealed case starts to be discharged. A protrusion of a rib is provided between the releasing portion and the joint portion.
