Abstract

Official abstract text for this publication.

A battery pack spacer is divided into a first region and a second region, the first region includes an end portion in a first direction and occupies half of an entire region of the spacer in a second direction from the end portion in the first direction, the second region includes an end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, and the second region has higher compressibility in the single cell arrangement direction than the first region.

First claim

Opening claim text (preview).

What is claimed is: 1 . A battery pack spacer which is arranged between adjacent single cells in a battery pack constructed by arranging a plurality of single cells in a predetermined arrangement direction, each of the single cells including terminals which protrude in a direction perpendicular to the arrangement direction, the battery pack spacer comprising, a first region and a second region, wherein the direction in which the terminals protrude is set as a first direction, a direction opposite to the first direction is set as a second direction, in the first direction and the second direction of the battery pack spacer arranged between the single cells, the spacer is divided into the first region and the second region, the first region includes an end portion in the first direction and occupies half of an entire region of the spacer in the second direction from the end portion in the first direction, the second region includes an end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, and the second region has higher compressibility in the arrangement direction than the first region. 2 . The spacer according to claim 1 , wherein the second region is mainly formed of a material having higher compressibility and/or a material having a lower withstand load than the first region. 3 . The spacer according to claim 1 , wherein the first region is mainly formed of a polyolefin resin. 4 . The spacer according to claim 1 , wherein the second region is mainly formed of an elastomer. 5 . A battery pack spacer which is arranged between adjacent single cells in a battery pack constructed by arranging a plurality of single cells in a predetermined arrangement direction, each of the single cells including terminals which protrude in a direction perpendicular to the arrangement direction, the battery pack spacer comprising, a first region and a second region, wherein the direction in which the terminals protrude is set as a first direction, a direction opposite to the first direction is set as a second direction, in the first direction and the second direction of the battery pack spacer arranged between the single cells, the spacer is divided into the first region and the second region, the first region includes an end portion in the first direction and occupies half of an entire region of the spacer in the second direction from the end portion in the first direction, the second region includes an end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, and the second region has a lower withstand load in the arrangement direction than the first region. 6 . The spacer according to claim 5 , wherein the second region is mainly formed of a material having higher compressibility and/or a material having a lower withstand load than the first region. 7 . The spacer according to claim 5 , wherein the first region is mainly formed of a polyolefin resin. 8 . The spacer according to claim 5 , wherein the second region is mainly formed of an elastomer. 9 . A battery pack spacer which is arranged between adjacent single cells in a battery pack constructed by arranging a plurality of single cells in a predetermined arrangement direction, each of the single cells including terminals which protrude in a direction perpendicular to the arrangement direction, wherein the direction in which the terminals protrude is set as a first direction, a direction opposite to the first direction is set as a second direction, and in the first direction and the second direction of the battery pack spacer arranged between the single cells, an end portion in the second direction has a smaller thickness in the arrangement direction than an end portion in the first direction. 10 . The spacer according to claim 9 , further comprising, a first region and a second region, wherein the first region includes the end portion in the first direction and occupies half of an entire region of the spacer in the second direction from the end portion in the first direction, the second region includes the end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, the second region is mainly formed of a material having higher compressibility and/or a material having a lower withstand load than the first region. 11 . The spacer according to claim 9 , further comprising, a first region and a second region, wherein the first region includes the end portion in the first direction and occupies half of an entire region of the spacer in the second direction from the end portion in the first direction, the second region includes the end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, wherein the first region is mainly formed of a polyolefin resin. 12 . The spacer according to claim 9 , further comprising, a first region and a second region, wherein the first region includes the end portion in the first direction and occupies half of an entire region of the spacer in the second direction from the end portion in the first direction, the second region includes the end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, wherein the second region is mainly formed of an elastomer. 13 . The spacer according to claim 9 , further comprising, a first region and a second region, wherein the first region includes the end portion in the first direction and occupies half of an entire region of the spacer in the second direction from the end portion in the first direction, the second region includes the end portion in the second direction and occupies half of the entire region of the spacer in the first direction from the end portion in the second direction, wherein a wedge-shaped space is formed in a region from a portion of the end portion in the second direction toward the inside of the spacer.
