Abstract: A battery carrier for receiving at least one battery module serving as a drive energy storage device for an electrically driven vehicle. The battery carrier can be connected to a body of the vehicle, including a substantially circumferential frame structure having longitudinal sides and transverse sides for forming a receiving area for the at least one battery module, wherein the battery carrier is integrally molded from a light metal material, in particular integrally cast from a light metal material. The receiving area encloses an area of at least 0.5 m2, in particular of at least 0.75 m2, particularly preferably of at least 1 m2. The present invention also relates to methods for die casting a substantially one-piece battery carrier from a light metal melt, in particular from an aluminum alloy melt.

Abstract: The invention provides a battery carrier which is provided for being fastened in a floor region of a supporting structure of an electrically driven motor vehicle. The battery carrier with a floor section and a side wall running around the floor section delimits a receiving space for at least one battery element to be positioned there. The side wall includes at least two side wall sections which are aligned at an angle ? of more than 0° relative to the floor section and meet in a corner region. In a such a battery carrier, the floor section is formed in one piece from a first aluminum material and side wall sections of the side wall meeting at least in one of the corner regions in each case, including the respective corner region, are formed in one piece from a second aluminum material which has a higher elongation at break A than the first aluminum material. The invention further discloses a method of manufacturing a battery carrier of the type according to the disclosure.

Abstract: With the method according to the invention, mould parts for casting moulds for light metal casting can be treated such that the danger of crack formation in the region of the surface sections of the mould part coming into contact with the light metal melt during casting is reduced to a minimum.
