Abstract: A housing device for a traction battery with fluid-based cooling in a vehicle. The traction battery has a plurality of a battery cells. The housing device includes a housing body, which forms an enclosed interior with a plurality of receiving positions for receiving the plurality of battery cells and a bottom region of which is designed to receive liquid fluid. An evaporation device is included for evaporating the liquid fluid. The evaporation device has a plurality of microchannel structures for forming microchannels. The microchannel structures extend in a vertical direction in the assembled state and have, in their lower region with respect to the vertical direction, at least one inlet opening for receiving liquid fluid from the bottom region of the housing body. During operation, liquid fluid enters the microchannels through the at least one inlet opening and heat is transferred from the battery cells to the liquid fluid in the microchannels. The liquid fluid evaporates in the evaporation device.

Abstract: A cooling device for cooling a traction battery of a vehicle by means of a fluid. The device includes an evaporation device for installing in a housing body of the traction body, at least one condensation device for installing on the vehicle outside of the housing body of the traction battery, and connection lines which conduct fluid evaporated in the evaporation device to the at least one condensation device and condensed fluid from the at least one condensation device back to the evaporation device. The evaporation device, the at least one condensation device, and the connection lines form a first cooling circuit. The first cooling circuit is designed in the form of a natural circulation.

Abstract: A battery cooling element, a battery module, and a method for manufacturing a battery cooling element. The battery cooling element has a flexible top side in the form of a flexible multilayer composite film. To cool a battery cell and/or a battery module, the heat transfer from the battery cell and/or the battery module into a cooling medium takes place through the comparatively low-cost and lightweight multilayer composite film, which has a high heat transfer coefficient.

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: The invention relates to a method for controlling the recovery of water in a motor vehicle, in which method, to recover water in an air-conditioning system (12) of the motor vehicle, air is cooled to a temperature below its dew point, and the water dropping out as a result of the cooling is collected in a water container (13). During water recovery, the air-conditioning system (12) is controlled by means of a water recovery control device (11), wherein, to control the water recovery by means of the water recovery control device (11), the air-conditioning system (12) is adjusted on the basis of at least one parameter value which is detected by a detection unit (10) and transmitted to the water recovery control device (11).

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.
