1. A housing assembly for receiving a battery module for an electric drive of an electrically drivable motor vehicle, comprising:
a frame comprising a plurality of frame elements made of a metallic material, with at least one of the frame elements having a variable sheet thickness over a longest length,
a base which is connected to the frame such that a sealed shell is formed, and
a cover detachably connectable to the frame, wherein the base, the frame and the cover enclose a receiving space for the battery module,
wherein the base includes an integrated cooling structure through which a coolant can flow;
wherein the base is made of a plurality of aluminium sheets joined together by roll bonding,
wherein the aluminium sheets are joined together in joining regions by rolling and are spaced apart from each other in hollow regions forming the cooling structure,
wherein the aluminium sheets comprise at least one flat sheet and at least one formed sheet which is connected to the flat sheet and forms the hollow regions, and
wherein the flat sheet has a greater tensile strength and greater yield strength than the formed sheet.
