Abstract: An impact detection device for a traction battery of a motor vehicle includes at least one air-filled chamber formed on an underbody element for the traction battery. An air-filled chamber is at least laterally sealed to outside and defined by a sealing material. A pressure hose and an introduction element for the pressure hose can be provided, wherein the air-filled chamber can be coupled to a pressure sensor through the pressure hose, and the introduction element can be attached to the underbody element and formed to couple the pressure hose to the air-filled chamber through the sealing material in a set position. The introduction element can be embedded by the sealing material which seals the air-filled chamber.

Abstract: A module cover for a battery module, which has a cell unit with at least one battery cell which includes a releasable vent opening. The module cover has a first region, which is associated with a vent opening region of the cell unit, in which the releasable vent opening of the at least one battery cell is arranged, and at least one second region different from the first region, which is associated with a cell region of the cell unit that is different from the vent opening region of the cell unit. The first region and the at least one second region of the module cover respectively include a plastic material. The at least one second region is formed with a continuous fiber reinforcement embedded in the plastic material and the first region is formed without a continuous fiber reinforcement.

Abstract: An underbody component for a motor vehicle, with a plate element which has a lower side and an upper side; at least one supporting element arranged on the upper side of the plate element, which is intended to support the plate element against a vehicle side structure and to space it apart. The supporting element is also designed as a partition, which divides the area above the plate element into multiple chambers; a sensor device which is intended to detect intrusion of the plate element into at least one of the chambers caused by an external force action on the lower side.

Abstract: A warning system and a warning method for a motor vehicle having a high-voltage battery. The warning system includes a battery housing having the high-voltage battery, an underride protection device, a spatially closed cavity, at least one pressure sensor, and an evaluation device. The spatially closed cavity is arranged in a vertical direction of the warning system above the underride protection device and below the battery housing and is designed to change a volume of the cavity upon a deformation of the underride protection device under the action of a predetermined external force on the underride protection device. The at least one pressure sensor is designed to detect a pressure change value that describes a change in pressure in the pressure in the cavity.
