Abstract

A battery housing for a vehicle battery includes side walls which laterally delimit an interior of the battery housing, with a mounting frame running externally around the side walls for mounting the battery housing on a chassis of an electric vehicle, and with a floor structural element delimiting the interior of the battery housing at the bottom, wherein a first reinforcing profile for reinforcing the floor structural element is arranged on said floor structural element, and/or a second reinforcing profile for reinforcing the mounting frame is arranged on said mounting frame.

First claim

The invention claimed is:

1. A battery housing for a vehicle battery, the battery housing comprising:
side walls which laterally delimit an interior of the battery housing, with a mounting frame running externally around the side walls for mounting the battery housing on a chassis of an electric vehicle;
a floor structural element delimiting the interior of the battery housing at the bottom; and
at least one reinforcing profile for reinforcing the mounting frame and arranged on said mounting frame, wherein the mounting frame comprises a mounting frame hollow structural element with a mounting frame cavity, wherein the at least one reinforcing profile is joined to a side wall of the side walls and arranged inside the mounting frame cavity, wherein the at least one reinforcing profile has one of a meander-like and top-hat profile along a length-wise cross-section which is arranged parallel to the side wall of the side walls.

2. The battery housing as claimed in claim 1 , wherein the reinforcing profile has a first profile cross-section along a first cross-sectional plane, and a second profile cross-section along a second cross-sectional plane parallel to the first cross-sectional plane, wherein the first and second profile cross-sections are different.

3. The battery housing as claimed in claim 1 , wherein the reinforcing profile has a first material thickness in a first region of the reinforcing profile and a second material thickness in a second region of the reinforcing profile, wherein the first and second material thicknesses are different.

4. The battery housing as claimed in claim 1 , wherein the reinforcing profile comprises a cut-out.

5. The battery housing as claimed in claim 1 , wherein the reinforcing profile is joined to an inner wall delimiting the floor cavity and the reinforcing profile is joined to a floor structural element.

6. The battery housing as claimed in claim 1 , wherein an edge reinforcing element is arranged between one of the side walls and the floor structural element of the battery housing and is connected, in particular joined, to a side wall and the floor structural element.
