Abstract: A degassing unit for an electronics case includes a base body attachable to the electronics case and configured to seal against a perimeter of an aperture in the electronics case, the base body including a degassing opening, a membrane covering the degassing opening of the base body and including at least one segmentation line penetrating through the membrane, and at least one support rib abutting adjacent segments of the membrane along the at least one segmentation line. Each of the membrane and the at least one support rib has a convex shape facing away from the base body.

Abstract: Climate module (1A, 1B) of a battery housing (3) includes an adsorber unit (25) for adsorbing humidity during an adsorption mode (M1) of the climate module (1A, 1B), a heater unit (22) for regenerating the adsorber unit (25) during a regeneration mode (M2) of the climate module (1A, 1B), an outlet (6) that is fluidly connectable to an inlet (7) of the battery housing (3), an airflow generator (19), and a valve system (V1, V2) for switching the climate module (1A, 1B) from the adsorption mode (M1) into the regeneration mode (M2) and vice versa. The climate module (1A, 1B) takes in ambient air (A) during the adsorption mode (M1), and the airflow generator (19) forces the intaken ambient air (A) through the adsorber unit (25) for dehumidifying the ambient air (A) and guides the dehumidified ambient air (A) via the outlet (6) and the inlet (7) of the battery housing (3) into the battery housing (3) during the adsorption mode (M1).
