Abstract: A bus bar has: a first joint part connected to an output terminal of the first cell; a second joint part connected to an output terminal of the second cell; and a projection that is disposed between the first joint part and the second joint part and protrudes in a stacking direction in which the cells and the bus bar are stacked. The projection has a first inclined part extending from the first joint part and has a second inclined part extending from the second joint part. The first inclined part and the second inclined part are arranged in such a manner that the first inclined part and the second inclined part are aligned with a predetermined interval W and that the predetermined interval gradually becomes wider from a first end side toward a second end side.

Abstract: A power storage module includes at least one power storage device, and a buffer member arranged with the power storage device in a first direction X. The buffer member includes a hard part having a predetermined hardness and a soft part softer than the hard part, the hard part and the soft part receiving a load in first direction X from the power storage device. The hard part changes its shape by receiving a load of a predetermined magnitude or more. The buffer member changes its state, by the hard part changing its shape, from a first state in which the load is received by the hard part to a second state in which the load is received by the soft part.

Abstract: A battery module includes: a plurality of batteries stacked together; and a busbar that electrically connects the plurality of batteries with each other. The busbar has: a main body that extends along axis X along which the batteries are stacked together; and a plurality of connectors that protrude from the main body along an axis that intersects with the axis along which the batteries are stacked together, and are electrically connected with terminals of the batteries, respectively. The plurality of batteries are divided into a plurality of battery units. Each of the plurality of battery units includes at least two of the plurality of batteries. The busbar connects the at least two of the plurality of batteries of each of the battery units with each other in parallel. The busbar connects the battery units with each other in series.

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.
