A battery module and a method of assembling a battery module are provided. The method includes selectively applying a light-cure adhesive to recesses in a first side of a carrier layer and inserting battery cells into respective recesses. The method further includes exposing the first side of the carrier layer to light to at least partially cure the light-cure adhesive with the carrier layer in a first orientation, moving the carrier layer into a second orientation, and exposing a second opposite side of the carrier layer to light to fully cure the light-cure adhesive. The recesses may include a sidewall having crush points spaced apart along the sidewall and a bottom portion having an opening between a pair of crush points, where adhesive is not disposed between the pair of crush points.

The present invention pertains to a supporting structure for receiving battery cells in a battery system of a hybrid or electrical vehicle, the supporting structure comprising a bottom plate and two side plates arranged on the bottom plate, wherein the inner sides of the two side plates and the bottom plate define an internal volume for receiving the battery cells and wherein each side plate comprises a flange at its outer side and wherein each flange comprises fixation means for fastening the supporting structure to an adjacent supporting structure.

The present invention pertains to a battery housing for receiving battery cells, preferably for use in an electric or hybrid vehicle, the battery housing comprising a bottom plate forming a base of the housing, wherein the bottom plate is connectable to another bottom plate of the same kind by means of a connection system to form a modular bottom of the housing.

Heating a battery and cooling an electric power conversion device are achieved together. This mobile body includes an electric motor, a battery, a thermoelectric conversion element, an electric power conversion device, and a controller. The electric motor is a driving source. The electric power conversion device is configured to convert electric power outputted from the battery into driving electric power for the electric motor. The electric power conversion device is disposed in direct contact or in indirect contact with the battery with the thermoelectric conversion element interposed therebetween. The controller is configured to control electric power to be supplied to the thermoelectric conversion element. The controller controls, in a case where the battery is in a predetermined low-temperature state, the electric power to be supplied to the thermoelectric conversion element to cause a surface of the thermoelectric conversion element coupled to the battery to serve as a heat dissipation surface.

A heat dissipation structure including a plurality of heat dissipating members, and a support plate for supporting the heat dissipating members. Each of the heat dissipating members includes a plurality of cushion members each having a hollow or a solid shape, and a heat conduction sheet covering an outer surface of the cushion members. The support plate includes a plurality of grooves for supporting the heat dissipating members in a direction orthogonal to a longitudinal direction of the heat dissipating members. Each of the grooves is a curved recess portion formed in a thickness direction, opened to the side of the heat dissipating member, formed to have a radius of curvature larger than a radius of curvature of the heat dissipating member, and to have a depth smaller than a circular conversion diameter of the heat dissipating member, and a battery provided with the heat dissipating structure.
