Abstract: A store housing for an electrical energy store of a motor vehicle includes multiple housing walls which surround a receiving space for receiving at least one storage component of the electrical energy store, wherein at least one of the housing walls has a passage opening for discharge of a liquid which has accumulated in the receiving space into surroundings of the store housing, and at least one valve which is designed to conduct the liquid away from the receiving space into the surroundings via the passage opening and to at least reduce ingress of liquid from the surroundings into the receiving space via the passage opening. The at least one valve has a passive valve arranged in or at the passage opening. The valve has a first flow resistance in a first flow direction from the receiving space into the surroundings and has a second flow resistance in a second flow direction from the surroundings into the receiving space, which second flow resistance is larger in comparison with the first flow resistance.

Abstract: A contactor has a first contact element and a second contact element as well as an electrically conductive connecting element. An actuator is designed to move the connecting element between a closed state and an open state, wherein, in the closed state, an electrically conductive connection between the first contact element and the second contact element is effected via the connecting element and, wherein, in the open state, no electrically conductive connection between the first contact element and the second contact element is effected by the connecting element. At least one measuring component of the connecting element is in the form of a measuring resistor. Measuring lines are electrically conductively connected to different ends of the measuring component so that a voltage that drops across the measuring component due to the current flowing through the measuring component can be measured via the measuring lines.
