Abstract
Official abstract text for this publication.
The present invention provides a battery pack that has a plurality of single cells arranged in an array direction, and a bus bar that electrically connects the plurality of single cells. The bus bar has a first bent portion that is bent in a direction away from each of the single cells, and a second bent portion that is bent in a direction opposite to the direction in which the first bent portion is bent. The first bent portion and the second bent portion are disposed side by side in the array direction, and extend from one end of the bus bar to the other end of the same so as to intersect with the array direction. The first bent portion is configured to expand gradually from the one end of the bus bar to the other end of the same. The second bent portion is configured to narrow gradually from the one end of the bus bar to the other end of the same.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery pack, comprising: a plurality of single cells arranged in an array direction; and a bus bar that electrically connects the plurality of single cells, wherein the bus bar has a first bent portion that is bent in a direction away from each of the single cells, and a second bent portion that is bent in a direction opposite to the direction in which the first bent portion is bent, the first bent portion and the second bent portion are disposed side by side in the array direction, extending from one end of the bus bar to the other end of the same so as to intersect with the array direction, the first bent portion is configured to expand in a width thereof gradually from the one end of the bus bar to the other end of the same, and the second bent portion being configured to narrow in a width thereof gradually from the one end of the bus bar to the other end of the same. 2 . The battery pack according to claim 1 , wherein the first bent portion and the second bent portion are disposed to be at least either point-symmetric with respect to a center of the bus bar or line-symmetric with respect to a centerline of the bus bar in the array direction. 3 . The battery pack according to claim 1 , wherein the single cells each have a power generation element, a battery case for storing the power generation element, and an external terminal attached to the outside of the battery case, the bus bar is electrically connected to the external terminal, and a welding joint is formed at a position where the external terminal is connected to the bus bar.
