Abstract: A battery module includes a battery stack having a plurality of batteries that are stacked and a heat transfer suppression member disposed between adjacent two of the batteries, a heat conductor that extends in stacking direction X of the batteries and is adjacent to the battery stack, and a heat absorber that intervenes between the battery stack and the heat conductor and contains an endothermic agent that is to start endothermic reaction at a temperature higher than or equal to a predetermined temperature.

Abstract: A battery module includes a battery stack having a plurality of stacked batteries, a first heat radiator facing first surface of battery stack, a first heat transfer component that is in contact with the first heat radiator and first surface to transfer heat from the battery stack to the first heat radiator, and a second heat radiator facing a second surface of the battery stack. The second surface extends in a direction intersecting with the first surface. The second heat radiator is thermally connected to the second surface directly or through the second heat transfer component. A positional relationship between the first heat transfer component and the battery stack is formed such that the center of the first heat transfer component (84) is more away from the second heat radiator than the center of the battery stack is in a direction along the first surface.
