Abstract: A power storage module includes an array including power storage devices each having first and second surfaces opposite to each other in a first direction, a first restraint member facing the first surface of each power storage device, and a second restraint member facing the second surface of each power storage device. Dimensions of the power storage devices in a second direction perpendicular to the first direction are larger than respective dimensions of the power storage devices. The power storage devices are arranged in a third direction perpendicular to the first and second directions. The first restraint member extends in the third direction and restrains the array in the third direction. The second restraint member extends in the third direction and restrains the array in the third direction. At least one of the first and second restraint members has a hole therein. The hole is a recess falling in the first direction or a through-hole passing through the restraint member in the first direction.

Abstract: A battery module includes: a battery stack having a plurality of batteries; a plurality of first restraining members and a plurality of second restraining members; and connecting members. The first restraining members and the second restraining members define a housing space for the battery stack. Each of the first restraining members has a first housing part extending in a direction intersecting a planar direction in which the battery stack, the first restraining members, and the second restraining members are arranged, and each of the second restraining members has a second housing part extending in the planar direction. Each of the connecting members connects each of the first restraining members and each of the second restraining members to each other by being housed in the first housing part of each of the first restraining members and in the second housing part of each of the second restraining members.

Abstract: An electrical storage module includes at least one electrical storage device, and a buffer member that is arrayed in first direction X together with the electrical storage device and receives a load in first direction X from the electrical storage device. The buffer member has a soft part and a hard part, which is positioned closer to an outer edge part of the buffer member than the soft part, and the soft part is more easily deformed than the hard part.

Abstract: An electrical storage module includes: at least one electrical storage device; and a buffer member that is arranged in first direction X together with the electrical storage device and is configured to receive a load from the electrical storage device in first direction X. The buffer member includes a first layer portion and a second layer portion arranged in first direction X. The first layer portion has first softened portions each formed of a through hole or a recessed part. The second layer portion has second softened portion each formed of a through hole or a recessed part. The first softened portion and the second softened portion are at least partially displaced from each other as viewed in first direction X.

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.
