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.

Abstract: A degassing channel for a battery in a motor vehicle designed to be arranged on a cell pack of the battery, which cell pack includes at least one battery cell, which has a releasable cell-degassing opening. The degassing channel has a first channel wall with a releasable wall opening that is assigned only to the cell-degassing opening, which wall opening can be released by a gas pressure of a gas escaping from the assigned cell-degassing opening when the degassing channel is arranged on the cell pack, so that the escaping gas can be directed through the released wall opening into an interior of the degassing channel.

Abstract: A crash structure for a vehicle, including a bumper crossmember of which the end portions are each connected to a corresponding longitudinal member via a crash box. End regions of the end portions each project in the vehicle transverse direction beyond the corresponding longitudinal member. In each case a first supporting element which protrudes in the direction of a corresponding wheelhouse is arranged at the end regions and, in an accident situation with slight overlapping of the other party in the accident, impinges on the corresponding longitudinal member. In each case a second supporting element is arranged at the end regions of the end portions and, in the accident situation with slight overlapping of the other party in the accident, impinges on a corresponding connecting region between the crash box and the longitudinal member.
