Abstract: A battery module including a plurality of battery cells, a first chassis, and a connection member. The battery cells are aligned in a first direction. The first chassis includes a plurality of first compartments in which the battery cells are housed one by one, and at least one second compartment that is partitioned in the first direction. The connection member includes a body that is housed in the second compartment, a pair of connection terminals that is mounted on a first face of the body and is electrically connectable to the electrodes of the battery cells via a conductive member. The first face faces in a second direction intersecting with the first direction, and a conductor that extends across the pair of connection terminals.

Abstract: According to one embodiment, a battery module includes first to fourth batteries and a case in which these batteries are housed. In the case, a first partition wall partitions the first and the second batteries and partitions the third and fourth batteries in a first direction, and a second partition wall partitions the first and third batteries and partitions the second and fourth batteries in a second direction intersecting the first direction. A fastening member fastens case members to each other at an intersection of the above two partition walls. The case includes a rib protruding on a surface of at least one of the first and second partition walls.

Abstract: A battery device includes a battery cell; an exterior member that accommodates the battery cell; and one or more foamed resin fixing members disposed between the battery cell and the exterior member. The foamed resin fixing members are formed of a foamed resin having self-adhesiveness.

Abstract: According to one embodiment, a battery module includes a plurality of batteries and a module housing. The module housing accommodates the plurality of batteries. The module housing is configured by connecting a plurality of cases in a first direction. At least one of the plurality of cases includes a vacuum pad adsorption region which is on an end surface in a second direction intersecting the first direction and on which a vacuum pad is adsorbable.

Abstract: According to an embodiment, a battery module includes cells each including a housing body including a bottom surface, a pair of main surfaces, and a pair of side surfaces, and a lid member opposed to the bottom surface and having electrode terminals; a case in which the cells are housed; conductive members electrically connecting the electrode terminals of the cells; and a wiring board placed at the upper portion of the conductive members on the case. The cells include a first group including cells stacked along a first direction, and a second group including cells stacked along a second direction. The side surfaces of cells of the first group are opposed to the main surfaces of the cells of the second group. The first group and the second group are connected in series.

Abstract: According to one embodiment, battery assembly includes casing, accumulators, and conductive member. The conductive member has two first walls, two second walls, and third wall. One of the first walls is connected to one of a cathode and an anode of one of the accumulators, and extended along a front surface of the casing. Other one of the first walls is connected to one of the cathode and the anode of other one of the accumulators, and extended along the front surface. The second walls are connected to the first walls via two first curve portions, respectively, and extended in direction crossing the front surface. The third wall is connected to the second walls via two second curve portions, respectively, and extended over between the two second walls in direction along the front surface at a position apart from the front surface.
