Abstract: A first connector of a battery connector includes a battery-side busbar first terminal including a battery-side first pin insertion hole and a load-side busbar first terminal including a load-side first pin insertion hole. A second connector includes a battery-side busbar second terminal including a battery-side second pin insertion hole and a load-side busbar second terminal including a load-side second pin insertion hole. The load-side first pin insertion hole is formed in a position where the load-side first pin insertion hole does not match the battery-side second pin insertion hole when the battery-side busbar second terminal and the load-side busbar first terminal are superimposed. The load-side second pin insertion hole is formed in a position where the load-side second pin insertion hole does not match the battery-side first pin insertion hole when the battery-side busbar first terminal and the load-side busbar second terminal are superimposed.

Abstract: A battery case accommodates therein a battery cell that has a first main surface and a second main surface opposite to the first main surface. The battery case includes: a chassis with which the first main surface of the battery cell comes into contact; an adjustment plate placed on the second main surface of the battery cell; and a holding plate that is formed from an elastic member and covers the second main surface of the battery cell with the adjustment plate between the holding plate and the battery cell.

Abstract: A bypass switch includes a pair of fixed conductors connected in parallel with a battery cell, a movable conductor disposed in a vertical direction with respect to the pair of fixed conductors, and a thermally actuated device. In the thermally actuated device, a single diode that generates heat by being energized, a metal plate, and solder are stacked and sandwiched between a first and second heat-insulating spacers. When the battery cell malfunctions, the diode is energized and generates heat that is transferred to the solder through the metal plate, causing the solder to melt, and thereby the thermally actuated device to be displaced. Displacement of the thermally actuated device causes the movable conductor to be displaced in the vertical direction with respect to the fixed conductors and inserted between the fixed conductors, electrically connecting the fixed conductors and forming a bypass circuit to short-circuit the malfunctioned battery cell.
