Abstract: An underbody protection apparatus is arrangable below a traction battery on the underbody of an at least semi-electrically driveable motor vehicle. The apparatus includes an underbody protection plate for protecting the underbody of the motor vehicle, a gas-conducting structure arranged between the traction battery and the underbody protection plate and arranged on the underbody protection plate for conducting a gas exiting from the traction battery along the underbody protection plate. The gas-conducting structure is arranged on the traction battery such that a gas can be introduced into the gas-conducting structure via a degassing outlet of the traction battery. The gas-conducting structure includes a plurality of branching points for branched conduction of the gas exiting from the traction battery along the underbody protection plate.

Abstract: An underride protection device for a battery-electric vehicle, having a sandwich arrangement with a core layer arranged between an upper cover layer and a lower cover layer made of a fiber-reinforced plastic material. In order to functionally improve the underride protection device, ribs are arranged on the upper cover layer, which are materially connected to the upper cover layer, wherein the ribs arranged on the upper cover layer are surrounded by a respective top layer, which is materially connected to the upper cover layer at two retaining sections.

Abstract: A motor vehicle, in particular with an electric drive, having a battery system and an underride protection plate. The underride protection plate is arranged in the motor vehicle at least in sections under the battery system. The battery system includes a battery module, which includes a first wall in a first region of the battery system and a second wall in a second region of the battery system. The underride protection plate is formed in such a way that the underride protection plate directly or indirectly abuts the battery system in the first region and in the second region at least in sections, and, between the first region and the second region, forms a first section of a gas channel between the battery system and the underride protection plate.
