Abstract: A battery carrier having a trough formed from shaped sheet metal, which has at least one trough side wall and a trough bottom connected to the trough side wall, a plurality of support profiles provided in the trough and affixed to the trough, at least one battery pack, which is affixed to at least two support profiles extending adjacent to the battery pack, a lid, which is detachably connected to said trough, and a heat exchanger, which is thermally connected to the battery pack and has at least one flow channel for a liquid. In order to enable a simple design and simple assembly and maintenance, it is proposed for the lid to form the heat exchanger, wherein the battery pack is arranged at a distance from the trough bottom and the trough bottom is permanently connected to the trough side wall or embodied of one piece with it.

Abstract: A battery compartment for a traction battery, having a lower housing part with housing side walls and a housing bottom; a housing cover; and a crash frame with a closed hollow profile form along the housing side walls. In order to enable a low weight and outstanding crash behavior, it is proposed that the crash frame be provided in the lower housing part and have crash profiles, wherein the housing side walls and the crash profiles respectively form a profile section in the closed hollow profile form of the crash frame.

Abstract: The invention relates to a process for producing sheet steel components having regions of differing ductility, in which either a sheet metal plate composed of a hardenable steel alloy is used to produce a component by deep-drawing and the deep-drawn component is then at least partially austenitized by a heat treatment and subsequently quench hardened in a die or the plate is at least partially austenitized by a heat treatment and shaped in the hot state, and is quench hardened during or after this, with the sheet metal plate having a zinc-based cathodic corrosion protection coating, characterized in that in regions of a desired higher ductility of the component, at least one additional sheet is attached to the plate, situated so that during the heat treatment, the plate is heated to a lesser degree there than in the remaining region.
