Problems solved by technology
[0005] However, in all metallic battery module housings, problems arise with the insulation of the electrical contacts with respect to the battery module housing
[0006] Furthermore, it is also known from the prior art to use battery module housings made of plastic, but such battery module housing parts have insufficient mechanical strength and are also limited in terms of their thermal conductivity.

Embodiment Construction
[0053] figure 1 A perspective illustration of the first housing element 2 of the battery module housing 1 according to the invention is shown. In this case, the first housing element 2 consists of a metallic material. Here, according to figure 1 The first housing element 2 consists of aluminum, wherein it can also consist of copper, nickel, steel or iron. The first housing element 2 has a base plate 4 and a plurality of intermediate walls 5 . as by figure 1 As can be seen, each of the intermediate walls 5 is respectively connected to the base plate 4 . In particular, the intermediate wall 5 is here arranged at right angles to the base plate 4 .
[0054] In this case, the intermediate wall 5 is formed as a plurality of receiving chambers 6 designed for receiving battery cells.
[0055] according to figure 1 In this case, one battery cell can each be accommodated between the two intermediate walls 5 , wherein it is also entirely possible to accommodate a plurality of batt...

A battery-module housing having a first housing element(2) and a second housing element(3), the first housing element(2) being made from a metallic material, and having a base plate(4) as well as a plurality of intermediate walls(5), which are connected to the base plate(4) and which form a plurality of receiving chambers(6) developed for the accommodation of battery cells, an intermediate wall(5)being developed for a mechanical separation of two battery cells able to be accommodated in the battery-module housing, and the second housing element(3) is made from a polymer material, the second housing element(3) in particular being developed in the form of a trough or a tub, and the base plate(4) of the first housing element(2) and the second housing element(3) jointly seal the plurality ofreceiving chambers(6) from an environment.
Description
technical field [0001] The invention is based on a battery module housing of the type according to the independent claim. Furthermore, the invention also relates to a method for producing such a battery module housing. The subject of the invention is also a battery module with such a battery module housing. Background technique [0002] It is known from the prior art to form battery module housings from aluminum or steel. [0003] In this case, steel has a high strength but also a high density, whereby the energy density of the weight of the battery module is reduced. [0004] In comparison, aluminum has a lower density and also exhibits good thermal conductivity. [0005] However, with all metallic battery module housings, the problem arises of the insulation of the electrical contacts relative to the battery module housing. [0006] Furthermore, it is also known from the prior art to use battery module housings made of plastic, but such battery module housing parts hav...
