Problems solved by technology

[0006] However, the various described battery modules are only capable of compensating to a limited extent the mechanical loads which act on the battery module, for example in the event of a collision of the motor vehicle with an obstacle and which can cause deformations of the battery module due to this mechanical load, which is Because the corresponding housing of the battery module and the battery cells of the corresponding battery module have a low rigidity

Embodiment Construction

[0028] The embodiments described below are preferred implementation forms of the present invention. In this exemplary embodiment, the individual components of the embodiment each represent individual features of the invention that can be considered independently of one another and which also improve the invention independently of one another. The disclosure content is therefore also intended to include combinations of features of the specific embodiments other than the indicated combinations. The embodiments described can also be supplemented by other features of the invention which have already been described.

[0029] In the figures, identical reference numerals designate functionally identical elements.

[0030] figure 1 A housing 10 is shown, which comprises two housing walls 20 arranged parallel to one another. The two housing walls 20 arranged parallel to one another each provide a housing wall surface 22 of the housing 10 on the outside. The two housing wall surface...

Abstract

The disclosure relates to a battery module (14) for a motor vehicle, including multiple prismatic battery cells (12), which are each enclosed by a housing (10). The respective housing (10) has two housing walls (20) arranged parallel to one another, which each provide a housing wall surface (22) of the housing (10) on the exterior. Multiple housings (10) are arranged in succession in the battery module (14) in such a way that in each case at least two exterior housing wall surfaces (22) abut one another. In each housing (10), the housing wall surfaces (22) each have a predetermined relief structuring (40), wherein the respective housing wall surfaces (22) abutting one another have relief structurings (40) formed corresponding to one another and are unconnected viewed perpendicularly in relation to the housing wall surface (22).

Description

technical field [0001] The invention relates to a battery module for a motor vehicle, which has a plurality of prismatic battery cells, and to a motor vehicle with such a battery module. Background technique [0002] A battery module comprising a plurality of prismatic battery cells usually has its own housing for each prismatic battery cell. The housing can be formed, for example, as an aluminum shell which is welded to a housing cover which has connections for the positive and negative poles of the battery. The aluminum shell can be produced, for example, by means of a deep-drawing method and thus has a flat surface. In a battery module, individual housings together with a plurality of battery cells received therein can be arranged side by side with each other, and by means of metal pressure plates and tensioning plates arranged on opposite ends of this type of battery cell pack. Screws or held together by means of metal ferrules. [0003] Document EP 2 495 786 A1 descr...
