Problems solved by technology

[0006] A disadvantage of the prior art is that the housing components and the battery cells are not designed for direct exposure of the exhausted cells and for the corresponding thermal load
Therefore, either separate fire protection measures are required, or fire protection is limited
In addition, further ignition of monomers may occur
These additional measures take up construction space and increase the number of manufacturing steps

Abstract

The invention relates to a battery housing (10) for at least one battery cell (16) of an electrical energy store (26) of an at least partially electrically operated motor vehicle (12), comprising an interior (14) of the battery housing (10), which interior is designed for arranging the at least one battery cell (16), the battery housing further comprises at least one protective layer (28) which isdesigned on at least one housing wall (18, 20, 22, 24) of the battery housing (10) and faces the interior (14), said protective layer (28) being designed as ceramic, glass or metal and being designedto generate an exhaust gas flow (30) when the battery cells (16) are evacuated (32) from the interior (14) of the battery housing (10). The invention also relates to a motor vehicle (12).

Description

technical field [0001] The invention relates to a battery housing for at least one battery cell of an electrical energy store of an at least partially electrically operated motor vehicle, the battery housing having a battery housing designed for arranging the at least one battery cell. The inner space of the battery cell also has at least one protective layer formed on at least one housing wall of the battery housing and facing the inner space. The invention also relates to a motor vehicle. Background technique [0002] Battery systems are known from the current state of the art which have a fireproof design in the event of cell exhaust. This should prevent damage to other battery cells and protect the vehicle and its occupants. When the cells are vented, gases with high temperatures escape, which can ignite. Here, housing components and battery cells can be exposed to these gases and be damaged. It is known in this respect that it is now necessary to introduce separate ...
