Abstract:
A battery pack includes a cell group, a spacer, a plurality of bus bars, and a bus bar holder. The cell group includes stacked unit cells, each including a cell body having a power generation element and an electrode tab having distal end portions bent along the stacking direction. The spacer is disposed between adjacent electrode tabs. The bus bars electrically connect the electrode tabs to each other. The bus bar holder that holds the bus bars. The bus bar holder includes a restricting member disposed between adjacent electrode tabs, and extends along the stacking direction to restrict the electrode tabs by sandwiching the electrode tabs with the spacer. Portions of the electrode tabs are welded to a surface of the bus bars facing the unit cells when the stacking direction positions of the portions of the electrode tabs are restricted by the restricting member and the spacer.

Claim (Index 1):
A battery pack comprising:\n a cell group including a plurality of unit cells stacked in a thickness direction, each of the unit cells including a cell body having a power generation element and a flat shape, and an electrode tab protruding out from the cell body, and each of the electrode tabs having distal end portions bent along the stacking direction of the unit cells; a spacer disposed between the electrode tabs that are adjacent to each other in a stacking direction to maintain an interval between the electrode tabs in the stacking direction; a plurality of flat plate shaped bus bars electrically connecting the electrode tabs of at least two of the unit cells to each other; and a bus bar holder that holds the bus bars, the bus bar holder comprising a restricting member disposed between portions of the electrode tabs that are adjacent to each other in the stacking direction of the unit cells, and the restricting member extending along the stacking direction and restricting a stacking direction positions of the portions of the electrode tabs that extend along the stacking direction by sandwiching the electrode tabs with the spacer, the portions of the electrode tabs that extend along the stacking direction being welded to a surface of the bus bars facing the unit cells in a state in which the stacking direction positions of the portions of the electrode tabs are restricted by the restricting member and the spacer.
