Battery module housing for accommodating at least one cell stack for use in a motor vehicle

A battery module housing for accommodating at least one cell stack of battery cells for use in a motor vehicle, said battery module housing comprising:

• (i) a plurality of housing units for accommodating the battery cells,
• (ii) a front and a rear cover member for closing the housing units,
• wherein the housing units are extrusion profiles and each comprise (i) a front and a rear face-side opening for introducing the battery cells and (ii) a housing wall arranged between the openings,
• wherein first and second housing units of the plurality of housing units are indirectly connected to one another, wherein each housing unit has a common width, a common length and a common height, and
• wherein the front and rear cover elements cover the front and rear face-side openings of the housing units, and
• (iii) an intermediate chamber for accommodating further battery cells, wherein the intermediate chamber is formed by (a) the housing walls of the first and second housing units that face one another and (b) two connecting elements in the form of metal sheets that connect the first and second housing units,
• wherein the intermediate chamber has a smaller width than the common width of the housing units,
• wherein a height and length of the intermediate chamber are the same as the common height and common length of the housing units, respectively,
• wherein the intermediate chamber forms a single chamber that is delimited by the housing walls of the first and second housing units and the two connecting elements, and
• wherein each connecting element has two ends, wherein one of the two ends is materially joined to the housing wall of the first housing unit and the other of the two ends is materially joined to the housing wall of the second housing unit.
