The present invention further discloses a traction battery for a motor vehicle and a motor vehicle having a traction battery.

Abstract: A battery housing for a traction battery. The battery housing includes a first housing shell, and a second housing shell which can be connected to the first housing shell, for bounding an interior formed to receive at least one battery module. The first housing shell has a first collar which runs at least partially around the first housing shell. The second housing shell has a second collar which runs at least partially around the second housing shell. The battery housing has at least one connection element having two pressure limbs. The at least one connection element engages around the first collar and the second collar and to clamp by the two pressure limbs of the connection element exerting a normal force on the first collar and on the second collar. The first collar and/or the second collar has at least one first latching means. The connection element has at least one second latching means.

Abstract: 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.

Abstract: 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.

Abstract: A traction battery including a battery shell and a plurality of battery modules arranged in the battery shell. Each battery module has a safety valve. The traction battery also includes a battery cover and a ventilation element for aerating and/or venting the traction battery. The traction battery has a guide means, which is regularly permeable, at least in part, to a designated fluid volume flow, for deflecting a designated fluid volume flow emerging in a designated manner from a safety valve in the direction of the ventilation element. The traction battery has a venting channel which extends from the guide means to the ventilation element.

Abstract: A battery shell, in particular, a battery shell for a traction battery of a motor vehicle, comprises a semi-permeable membrane that is integrally bonded or frictionally connected to the battery shell.

Abstract: 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.

Abstract: 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.

Abstract: 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.
