A battery module includes a stacked structure including: at least a plurality of stacked battery units; an insulating rod member passing through the stacked structure; and a tightening member that tightens the stacked structure from both ends of the insulating rod member passing through the stacked structure. The tightening member tightens the stacked structure to fasten the battery units, so that the close contact portions of the conductive members of adjacent ones of the battery units are brought in close contact with each other and the adjacent battery units are electrically connected with each other.

Battery module, electricity storage device, electricity storage system, electronic device, electric-powered vehicle, and power system

Provided is a battery module including a plurality of stacked battery units. Each of the battery units is arranged in a manner that a face of a heat-transfer plate held by a battery support body formed from an insulating material and a main face of a battery cell oppose each other.

Battery unit, battery module, power storage system, electronic device, power system, and electric vehicle

A battery module is provided. The battery module includes a battery module comprising a plurality of battery units comprising a pair of terminals respectively; and a connector comprising insertion portions, wherein the pair of terminals are inserted into the insertion portions and the plurality of terminals are electrically connected to each other.

Battery module

A battery unit includes a battery cell that charges and discharges electric power; and a bracket that has an outer peripheral wall portion surrounding an outer peripheral side of the battery cell, and a support body which is provided inside the outer peripheral wall portion and supports the battery cell, wherein two battery cells are inserted from a front surface side and a back surface side of the bracket into the outer peripheral wall portion and are mounted on both side surfaces of the support body.

Battery unit with peripheral bracket and internal support body

A battery module includes a plurality of battery supports each having a face orthogonal to the stacking direction, and a side face, the battery supports each containing a plurality of cells and being made of an insulating material, a coupling part that is located between the face of one battery support and the face of another adjacent battery support, and contracts in the stacking direction upon stacking the battery supports to bring the faces of the battery supports into intimate contact, a group of cells including the battery supports stacked with the coupling part being placed between the battery supports, a base plate, and first and second regulating plates placed facing each other in a standing position on the base plate, the first and second regulating plates sandwiching the group of cells arranged between the first and second regulating plates and stacked with the coupling part being contracted.
