In its edge area, the base has at least one embossment, which is offset into the trough interior and follows the course of the adjacent side wall, with a connection section, which is offset with respect to the base and to which the frame structure is connected, and with a transition section arranged between the connection section and the base. The transition section has an offset amount with respect to the base that corresponds at least to the material thickness of the base. ## Claims ### Claim 1 A battery housing for a vehicle comprising: a frame structure and a trough with a base and with side walls connected to the base forming a trough interior, wherein the base has at least one embossment which is offset into the trough interior and which follows the course of an adjacent side wall, wherein the embossment has a connection section and a transition section, the connection section is offset relative to the base by an offset amount and connected to the frame structure, and the transition section is arranged between the connection section and the base, wherein the transition section has a maximum offset amount with respect to the base, and the maximum offset amount corresponds at least to a material thickness of the base, such that as a result of the maximum offset amount of the transition section and the connection section being offset from the base, a force introduced laterally into the battery housing via the frame structure is introduced into the battery housing above a plane of the base facing into the trough interior and, due to the transition section offsetting the connection section from the base, a torque (bending moment) acts via the transition section on an adjoining region of the base, with a direction of the torque pointing away from the trough interior of the trough. ### Claim 2 (depends on 1) The battery housing of claim 1, wherein the maximum offset amount of the transition section corresponds to at least approximately twice the material thickness of the base. ### Claim 3 (depends on 1) The battery housing of claim 1, wherein the transition section is inclined in a steepest section thereof with respect to the plane of the base. ### Claim 4 (depends on 1) The battery housing of claim 1, wherein the offset amount of the connection section with respect to the base is the same as the maximum offset amount of the transition section. ### Claim 5 (depends on 1) The battery housing of claim 1, wherein a frame structure part of the frame structure is connected to the connection section on an outside thereof facing away from the trough interior. ### Claim 6 (depends on 5) The battery housing of claim 5, wherein a side of the frame structure part facing the transition section is spaced apart from a surface of the transition section, said surface of the transition section facing away from the trough interior and toward the frame structure part, which is connected to the connection section. ### Claim 7 (depends on 5) The battery housing of claim 5, wherein the trough is a one-piece, deep-drawn component. ### Claim 8 (depends on 7) The battery housing of claim 7, wherein the trough is made of steel or aluminum. ### Claim 9 (depends on 5) The battery housing of claim 5, wherein the frame structure part is a first frame structure part, and a second frame structure part of the frame structure is attached to the side wall of the trough adjacent to the connection section or to a section thereof. ### Claim 10 (depends on 9) The battery housing of claim 9, wherein the first frame structure part connected to the connection section and the second frame structure part supported on the side wall of the trough are connected and form a hollow chamber profile together with the side wall the trough. ### Claim 11 (depends on 1) The battery housing of claim 1, wherein a frame structure part of the frame structure forming a side wall of the trough is connected to the connection section on an inside thereof facing the trough interior. ### Claim 12 (depends on 11) The battery housing of claim 11, wherein the base of the trough is a one-piece, deep-drawn component. ### Claim 13 (depends on 12) The battery housing of claim 12, wherein the base is made of steel or aluminum. ### Claim 14 (depends on 1) The battery housing of claim 1, wherein the base has two embossments arranged on opposite sides of the base. ### Claim 15 (depends on 1) The battery housing of claim 1, wherein the base has a circumferential embossment following the side walls of the trough. ### Claim 16 (depends on 1) The battery housing of claim 1, wherein the battery housing further comprises at least one battery module resting on the embossment.
