摘要: 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.

摘要: 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.
