Abstract
Official abstract text for this publication.
A battery pack disclosed herein includes a plurality of rectangular secondary batteries that are disposed along an arrangement direction, and a spacer that is disposed between the rectangular secondary batteries that are adjacent in the arrangement direction. The spacer includes an elastic part including a plurality of hollow parts extending along the arrangement direction and configured to be elastically deformable in the arrangement direction, and a heat insulation part disposed between the elastic part and the rectangular secondary battery in the arrangement direction and having lower heat conductivity than the elastic part.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery pack comprising: a plurality of rectangular secondary batteries that are disposed along a predetermined arrangement direction; and a spacer that is disposed between the rectangular secondary batteries that are adjacent in the arrangement direction, wherein the spacer includes an elastic part including a plurality of hollow parts extending along the arrangement direction and configured to be elastically deformable in the arrangement direction, and a heat insulation part disposed between the elastic part and the rectangular secondary battery in the arrangement direction and having lower heat conductivity than the elastic part. 2 . The battery pack according to claim 1 , wherein the elastic part has a honeycomb structure. 3 . The battery pack according to claim 1 , wherein a ratio of a total area of the plurality of hollow parts to an entire area of the elastic part in a surface of the elastic part that is orthogonal to the arrangement direction is 0.35 or more and 0.8 or less. 4 . The battery pack according to claim 1 , wherein an area of a surface of the elastic part that is orthogonal to the arrangement direction is less than or equal to an area of a surface of the heat insulation part that is orthogonal to the arrangement direction. 5 . The battery pack according to claim 1 , wherein in the elastic part, one end part of the plurality of hollow parts in the arrangement direction is closed and the other end part thereof is open. 6 . The battery pack according to claim 1 , wherein a part of the elastic part is disposed in the heat insulation part. 7 . The battery pack according to claim 1 , wherein the elastic part and the heat insulation part are integrated by a binding member. 8 . The battery pack according to claim 1 , wherein the spacer further includes a base part with a flat plate shape. 9 . The battery pack according to claim 1 , wherein the elastic part includes a hole part that communicates between the plurality of hollow parts. 10 . The battery pack according to claim 1 , wherein the hollow part has a tapered shape along the arrangement direction.
