In addition, the cover includes an electrically conductive layer which forms an electromagnetic shield.
Claims9
A cover for a battery housing of a high-voltage vehicle battery, comprising:
- a composite material formed from a polymer matrix and an at least one fire retardant material embedded in said polymer matrix,
- wherein the cover has an electrically conductive layer applied to a top side of the composite material, which, when the cover is installed in a correct position on the battery housing, the top side faces away from an inner space which is enclosed by the battery housing and the cover,
- wherein the electrically conductive layer is between 0.2 mm and 0.5 mm thick, forms an electromagnetic shield suitable for shielding the high-voltage vehicle battery, and sealingly closes any pores of the composite material so as to ensure a fluid-tightness of the cover,
- wherein at least 80% of the cover by volume or weight is formed from the polymer matrix,
- wherein the cover closes off the housing in a fluid-tight manner.
