Abstract: A battery pack may include a fusible link plate having a bent shape. The fusible link plate may include: a first plate part extending in a first direction; a second plate part extending in a second direction; and a bent part connecting the first plate part to the second plate part. The first plate part, the second plate part, and the bent part may be disposed along a first plane that is along both the first direction and the second direction. The first plate part may include a portion having a first cross-sectional area. The second plate part may include a portion having a second cross-sectional area. The bent part may include a first fusible part having a third cross-sectional area. The third cross-sectional area may be smaller than the first cross-sectional area and smaller than the second cross-sectional area.

Abstract: A battery pack contains a plurality of battery cells that includes a first battery cell and a second battery cell; a first thermistor disposed closest to the first battery cell among the battery cells; a second thermistor disposed closest to the second battery cell among the battery cells. A case of the battery pack holds the battery cells, the first thermistor, and the second thermistor. The first battery cell is disposed such that at least one of the other battery cells is interposed between the first battery cell and a wall surface of the case in a direction orthogonal to a longitudinal direction of the first battery cell. The second battery cell is disposed such that none of the other battery cells is interposed between the second battery cell and the wall surface of the case in a direction orthogonal to a longitudinal direction of the second battery cell.
