Abstract
Official abstract text for this publication.
Provided is a battery pack including: a first battery group in which a plurality of storage batteries having a battery can side surface and a battery can bottom surface linked to the battery can side surface are laminated so that the battery can side surfaces face each other; a second battery group in which a plurality of storage batteries having a battery can side surface and a battery can bottom surface linked to the battery can side surface are laminated so that the battery can side surfaces are face each other; and a case housing the first battery group and the second battery group, wherein the facing surfaces of the first battery group and the second battery group are directly or indirectly thermally connected to each other.

The invention claimed is: 1. A battery pack, comprising: a first battery group in which a plurality of storage batteries having a battery can wide side surface, a battery can narrow side surface, and a battery can bottom surface linked to the battery can wide side surface and the battery can narrow side surface are laminated so that the battery can wide side surfaces face each other; a second battery group in which a plurality of storage batteries having a battery can wide side surface, a battery can narrow side surface, and a battery can bottom surface linked to the battery can wide side surface and the battery can narrow side surface are laminated so that the battery can wide side surfaces face each other; and a case housing the first battery group and the second battery group, wherein the battery can narrow side surfaces of the first battery group and the second battery group are disposed to face each other, a first heat transfer member is disposed between the first battery group and the second battery group, the first heat transfer member is closely adhered on the battery can narrow side surface of the first battery group and the battery can narrow side surface of the second battery group, the first battery group is interposed between the first heat transfer member and a second heat transfer member, the second battery group is interposed between the first heat transfer member and a third heat transfer member, and the battery can wide side surfaces of a storage battery of the first battery group and a storage battery of the second battery group are closely adhered on the bottom surface of the case, and wherein each of the first, second, and third heat transfer members is a solid, flat metal plate, and wherein a thickness of the first heat transfer member is smaller than thicknesses of the second heat transfer member and the third heat transfer member. 2. A battery pack, comprising: a first battery group in which a plurality of storage batteries having a battery can wide side surface, a battery can narrow side surface, and a battery can bottom surface linked to the battery can wide side surface and the battery can narrow side surface are laminated so that the battery can wide side surfaces face each other; a second battery group in which a plurality of storage batteries having a battery can wide side surface, a battery can narrow side surface, and a battery can bottom surface linked to the battery can wide side surface and the battery can narrow side surface are laminated so that the battery can wide side surfaces face each other; and a case housing the first battery group and the second battery group, wherein the battery can narrow side surfaces of the first battery group and the second battery group are disposed to face each other, a first heat transfer member is disposed between the first battery group and the second battery group, the first heat transfer member is closely adhered on the battery can narrow side surface of the first battery group and the battery can narrow side surface of the second battery group, the first battery group is interposed between the first heat transfer member and a second heat transfer member, the second battery group is interposed between the first heat transfer member and a third heat transfer member, and the battery can wide side surfaces of a storage battery of the first battery group and a storage battery of the second battery group are closely adhered on the bottom surface of the case, and wherein each of the first, second, and third heat transfer members is a solid, flat metal plate, and wherein a thickness of the first heat transfer member is larger than thicknesses of the second heat transfer member and the third heat transfer member. 3. The battery pack according to claim 1 , wherein a thickness of the first heat transfer member is 15 mm.
