The charging socket cover is arranged to be displaceable relative to the body in the region of the opening of the body. An electrical supply element is arranged adjacent the charging socket, wherein the charging socket includes an electrical plug connector for electrically connecting the charging socket to the supply element and/or sliding contact elements and/or jaw contact elements for electrically connecting the charging socket to the supply element.

Abstract: A directly cooled battery module including at least one module casing and a plurality of battery cells arranged within the module casing. The module casing encloses the plurality of battery cells at least in some regions, and the battery cells have a vertical axis and first and second end faces, which are mutually spaced in the direction of the vertical axis, and are arranged successively in the form of a cell packet in a stacking direction which is transverse to the vertical axis. The battery module also includes a fluid supply device with at least one inlet opening, which conducts a cooling liquid to the battery cells when operated as intended, and at least one outlet opening for freely discharging the cooling liquid out of the module casing and/or the cell packet and into the surroundings of the module casing or a battery housing.

Abstract: Gas scrubbing apparatus for absorbing carbon dioxide from the ambient air. The apparatus includes a scrubbing chamber with a raw gas inlet for bringing in the ambient air stream containing carbon dioxide to be scrubbed, an absorbent inlet for bringing in an absorbent, a clean gas outlet for discharging the scrubbed ambient air stream and an absorbate outlet for discharging an absorbate that has absorbed the carbon dioxide. The clean gas outlet is fluidically connected to a drying apparatus having at least one drying unit, which is configured to absorb the water contained in the clean gas in a drying process and remove it in a regeneration process. The drying apparatus is fluidically connected to the absorbent inlet and/or to the raw gas inlet such that the water removed in the regeneration process is brought into the scrubbing chamber via the raw gas inlet and/or the absorbent inlet.
