Abstract: A high-voltage battery, in the battery housing of which a number of cell modules are arranged, wherein combustion gas emitted in the event of a thermal battery cell event in a battery cell of one of the cell modules flows freely to an emergency degassing outlet of the battery housing via an installation gap inside the battery. A number of separate heat shield material portions are arranged in the installation gap inside the battery between the cell module top and the housing cover, each of which is associated with a cell module and has at least one elastically resilient pressing element which pushes the heat shield material portion with a pressing force such that the heat shield material portion is in pressed contact with the top of the cell module.

Abstract: The invention relates to a high-voltage battery, in the battery housing of which a number of cell modules are arranged, the cell module top of which is spaced apart from a housing cover of the battery housing in a vertical direction of the housing via an installation gap inside the battery, wherein combustion gas is emitted in the event of a thermal battery cell event in a battery cell of one of the cell modules and can be guided to an emergency degassing outlet of the battery housing via the installation gap inside the battery. According to the invention, a number of separate heat shield material portions are arranged in the installation gap inside the battery between the cell module top and the housing cover, each of which heat shield material portions is associated with a cell module.

Abstract: A composite material with a ballistic protective effect having a first, outer layer made of a first steel alloy and at least one second layer which is arranged under the first layer and is made of a second steel alloy. The composite material with a ballistic protective effect allows for a reduction in the weight or the wall thicknesses of the composite material in comparison to conventional composite ballistic materials, by utilizing a first steel alloy of the first layer that has the following alloy constituents in percent by weight (% by weight): 0.06%?C ?1.05%, 0.05%?Si?1.65%, 0.3%?Mn?2.65%, 0.015%?Al?1.55%; Cr?1.2%, Ti?0.13%, Mo?0.7%, Nb?0.1%, B?0.005%, P?0.08%, S?0.01%, Ni?4.0%, and V?0.05%, the remainder being Fe and inevitable impurities. The second layer of the composite material having a higher elongation than the first layer.
