Insbesondere sind die Verbindungselemente des Gehäuses und die Verbindungselemente der Batteriemodule komplementäre Strukturen, wobei die Verbindungselemente des Gehäuses an der Innenseite des Gehäuses und die Verbindungselemente an den Batteriemodulen, vorzugsweise an den Endplatten an- geordnet sind. Beispielsweise können die Verbindungselemente an der Innenseite des Gehäuses Löcher sein und die Verbindungselemente an den jeweiligen Endplatten der Batteriemodule können Stifte zum Einstecken in die Löcher des Gehäuses sein. Dadurch kann auf einfache Weise ein Batteriemodulsystem aus mehreren Batteriemodulen zusammengebaut werden. Beispielsweise kann durch ein Stifte-Loch System eine zusätzliche Fixierung der Batteriemodule in dem Gehäuse des Batteriemodulsystems eingespart werden. Mit Hilfe der Verbindungselemente des Gehäuses und der Verbindungselemente der Batteriemodule können zusätzliche Arbeitsschritte zum Fixieren der Batteriemodule im Gehäuse des Batteriemodulsystems weggelassen werden, wodurch ein Zusammenbau des Batteriemoduls vereinfacht werden kann. Weiterhin kann dadurch das Batteriemodulsystem nach einem Betriebsleben einfacher recycelt werden. Weiterhin ist es möglich, sowohl das Gehäuse als auch viele Teile der Batteriemodule und des Batteriemodulsys- tems aus einem Kunststoff oder einem Polymer herzustellen, wodurch das Gewicht des Batteriemoduls verringert werden kann. Weiterhin können die Batteriemodule des Batteriesystems derart hergestellt werden, dass diese gleiche Bauteile verwenden. Dadurch kann das Batteriemodulsystem einfacher hergestellt werden, da überwiegend identische Bauteile verwendet werden. Weiterhin kann das Gehäuse derart ausgestaltet sein, dass es die Batteriemodule hermetisch umschließen kann, wobei lediglich Öffnungen für Anschlüsse in dem Gehäuse vorhanden sind, so dass die Batteriemodule ihre gespeicherte Energie nach außen abgeben können und falls nötig auch Kühlmittel in das Gehäuse geleitet werden kann.

For example, the connection elements on the inside of the housing may be holes and the connection elements on the respective end plates of the battery modules may be pins for insertion into the holes of the housing. As a result, a battery module system can be assembled from a plurality of battery modules in a simple manner.

With the help of the connecting elements of the housing and the connecting elements of the battery modules additional operations for fixing the battery modules in the housing of the battery module system can be omitted, whereby an assembly of the battery module can be simplified. Furthermore, this makes it easier to recycle the battery module system after an operational life.
