    Abstract: A cell module includes: a battery cell group configured with a plurality of cylindrical battery cells; a positive current collector; and a negative current collector. The negative current collector has: a substrate disposed on a sealing body side of the cylindrical battery cells such that the negative current collector covers the battery cell group; and a current collecting pin protruding toward the battery cell group from the substrate. The current collecting pin is inserted into a gap between the cylindrical battery cells along an axial direction of such battery cells, and presses the side surfaces of outer cans of at least two cylindrical battery cells neighboring each other.

    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 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 a plurality of power storage devices and a bus bar electrically connecting the plurality of power storage devices. Each power storage device has a housing and a pair of output terminals disposed on a first surface of the housing. The bus bar has the plurality of terminal connections connected to the output terminals of each power storage device, and a linking part connecting the plurality of terminal connections. Each terminal connection part has a first part connected to each output terminal and a second part continuous from the first part and extending along a second surface spreading in a direction intersecting the first surface of the housing. Each linking part has a third part that connects the second parts of the adjacent terminal connections to each other.

    Abstract: A battery module includes battery stacks, a first restraining part, and a plurality of second restraining parts. The first restraining part has: a flat plate part; a plurality of first wall parts that protrude from a main surface of the flat plate part, extend in a stacking direction of the batteries, and are arranged in a first direction; and second wall parts extending in the first direction at end parts of each wall part. The second restraining parts are disposed individually corresponding to the first wall parts and each have: a belt part extending parallel to the flat plate part; a third wall part protruding from the belt part toward the first wall part and extending in the stacking direction; and fourth wall parts extending in the first direction at end parts of the third wall part. There are arranged a plurality of housing spaces for the battery stacks.
