A battery housing assembly includes a battery housing which encloses an interior for receiving a plurality of battery cells. A heat transfer device which has an inlet, an outlet, and at least one fluid channel arranged fluidically therebetween. The fluid flows through the heat transfer device from the inlet to the outlet via the at least one fluid channel that is arranged in the interior. A contact side of the channel is pressed against at least one contact element to the battery cells in order to transfer heat. At least one expansion element, as a result of the fluid in the heat transfer device being pressurized, expands in order to press the at least one fluid channel against the at least one contact element by bracing against a bracing surface.

Battery housing assembly with heat transfer device, and traction battery with battery housing assembly

A battery casing system for a traction battery in a motor vehicle, said battery casing system comprising a battery casing having a plastic battery casing shell which at least partially defines a battery casing volume for accommodating at least one battery component. The battery casing system of the invention is characterized in that same includes at least one reinforcing means which can be connected to an outer face of the battery casing shell and which is formed separately from the battery casing shell. The invention further relates to a traction battery comprising a battery casing system as well as to a motor vehicle comprising a traction battery.

Fastening of crash parts on battery casings

The invention relates to a battery cooling element having: an outer surface for resting at least in regions against a battery cell and/or for resting at least in regions against a battery module comprising at least two battery cells; an inner chamber for receiving a cooling medium, which inner chamber is surrounded at least in regions by the outer surface; and a cooling medium inlet connected to the inner chamber and a cooling medium outlet connected to the inner chamber, wherein the outer surface is made, at least in regions, of a thermally conductive, flexible film which can be shaped by a fluid pressure of the cooling medium.

Battery cooling element; battery module unit and battery module

A battery casing for accommodating at least one battery component in a battery casing volume, said battery casing having at least one plastic battery casing shell, which at least partly defines the battery casing volume, and at least one fastening device for attaching the battery component to the battery housing shell, the battery casing being characterized in that the battery casing shell includes at least one reinforcing structure which extends into the battery casing volume, and the fastening device is supported on the reinforcing structure. The present invention further discloses a traction battery for a motor vehicle and a motor vehicle having a traction battery.

Battery casing, traction battery and motor vehicle

The invention relates to a battery shell, in particular a battery shell of a traction battery, the battery shell being formed from plastics material, the battery shell having a fastening system for fastening a component to the battery shell, the fastening system having a guide rail, an inner profile and a fastening element, the guide rail being integrally or interlockingly connected to the battery shell, the inner profile being guided by the guide rail, the fastening element being designed to establish a connection between the component and the inner profile.

Battery shell, traction battery and motor vehicle

A battery housing arrangement, in particular a battery housing assembly of a vehicle traction battery which can be temperature-controlled by a fluid, comprises a battery housing which encloses an interior space for receiving battery cells, and a heat transmission device which has an inlet tube, an outlet tube and a heat exchanger element arranged fluidically therebetween. The fluid is able to flow through the heat transmission device from the inlet tube via the heat exchanger element to the outlet tube. The heat exchanger element can be accommodated in the battery housing. The battery housing has at least one through-opening for feeding through the inlet tube and the outlet tube, and the battery housing has at least one closure element which is inserted into the at least one through-opening and forms a closure between the inlet tube and/or the outlet tube and the at least one through-opening.
