A battery pack comprising:
- cells each including a battery main body in which a power generation element is received within an outer member, and electrode tabs including a positive electrode tab and a negative electrode tab which are connected with the power generation element, and which are provided to protrude from end portions of the outer member;
- frame members each including a front surface and a back surface on which a pair of the cells are mounted;
- conductive members each of which is disposed on a frame member, each of which electrically connects electrode tabs of the pair of the cells, and each of which includes connection portions that extend, respectively, along the front surface and the back surface of one of the frame members, and that are connected, respectively, with the electrode tabs of the pair of the cells, and an extension portion connecting the connection portions;
- and
- a bus bar which electrically connects the conductive members disposed on the frame members of the plurality of the frame members, and which are adjacent in a stacking direction of the frame members.
A method of manufacturing a battery pack comprising:
- preparing a cell including a battery main body which is formed by receiving a power generation element in an outer member, electrode tabs including a positive electrode tab and a negative electrode tab which are protruded from an end portion of the outer member;
- a cell holding process of mounting a pair of cells on a front surface and back surface of a frame member;
- an electrode tab connecting process of electrically connecting the electrode tabs of the pair of the cells by using a conductive member disposed to the frame member;
- and
- a conductive member connecting process of electrically connecting conductive members disposed on frame members of a plurality of stacked frame members, which are adjacent to each other, by using a bus bar,
- wherein each of the conductive members includes connection portions that extend, respectively, along a front surface and a back surface of one of the frame members, and are connected, respectively, with the electrode tabs of the pair of the cells, and
- wherein the connection portions are connected by an extension portion.
