Abstract
A method for producing a high-voltage battery unit, particularly for vehicles, includes producing a housing, which has a plurality of housing walls coating interior sides of the housing walls with a heat-resistant metal foil, introducing an electrical battery and cooling system into the housing, and sealing the housing.
Claims11
A method for producing a high-voltage battery unit, the method comprising:
- providing a housing having a plurality of housing walls;
- covering interior sides of the housing walls with a heat-resistant metal foil;
- introducing an electrical storage system and a cooling system into the housing, wherein the cooling system comprises at least one component that is displaceable at least to a predetermined extent with respect to the housing walls during operation of the high-voltage battery unit;
- introducing a flexible contact element between the at least one component and the heat-resistant metal foil;
- and
- sealing the housing,
- wherein, before covering the interior sides of the housing walls, the heat-resistant metal foil is shaped by at least one of thermoforming, embossing, or folding of the heat-resistant metal foil, such that a shape of the heat-resistant metal foil corresponds to an interior shape of the housing, and
- wherein the flexible contact element prevents the heat-resistant metal foil from slipping when the at least one component is displaced.
