COVERING FOR A BATTERY MODULE OR FOR A BATTERY

In order to create a cover for a battery module or for a battery store that comprises a plurality of battery cells, said cover serving not only as contact protection or as protection from the ingress of particles, but also fulfilling the function of a propagation protection by means of which a propagation of a thermal fault from one battery cell of the battery module or the battery store to other battery cells of the battery module or the battery store is able to be prevented or at least delayed, it is proposed that the cover comprises a first layer facing toward the battery cells in the mounted state of the cover and a second layer facing away from the battery cells in the mounted state of the cover, wherein the first layer comprises at least one penetration device, which enables a passage of hot gas from a battery cell through the first layer at a penetration point, and wherein the gas that has passed through the first layer is able to be dissipated from the penetration point in an interspace between the first layer and the second layer.
