Offenbarung der Erfindung Disclosure of the invention
Die Erfindung geht aus von einem Batteriemodul mit einer Vielzahl von zu einem Batteriepack zusammengefassten Batteriezellen, die jeweils in einem Metallgehäuse mit einer elektrisch isolierenden Beschichtung untergebracht sind und mit zwei Adapterplatten, die seitlich an äußeren Batteriezellen des Batteriepacks anliegen. Das Batteriemodul zeichnet sich dadurch aus, dass ein Halbteil aus einem elektrisch isolierenden Material zwischen der Adapterplatte und einer äußeren Batteriezelle angeordnet ist, welches zumindest die zur Adapterplatte weisenden umlaufenden Kanten der äußeren Batteriezelle abdeckt. The invention is based on a battery module with a plurality of battery cells combined into a battery pack, which are each housed in a metal housing with an electrically insulating coating and with two adapter plates which rest laterally on outer battery cells of the battery pack. The battery module is characterized in that a half part of an electrically insulating material is arranged between the adapter plate and an outer battery cell, which covers at least the circumferential edges of the outer battery cell facing the adapter plate.
Bei dem Verbau in einem Batteriesystem müssen metallische Zellgehäuse gegenüber ihrer Umgebung, zum Beispiel einer benachbarten Batteriezelle, dem Modul oder Batteriegehäuse, elektrisch isoliert werden. Bisher werden für die elektrische Isolation selbstklebende Folien oder Schrumpfschläuche verwendet. Beim Einsatz von Folien besteht jedoch der Nachteil, dass an den Kanten Überlappungen des Klebebandes notwendig sind, um diese zu isolieren. Schrumpfschläuche decken die Ecken und Kanten ebenfalls nur mangelhaft ab. Dieses Problem tritt speziell bei der Isolation der ersten und letzten Zelle im Batteriemodul, an denen die Adapterplatten der When installed in a battery system, metallic cell casings need to be electrically insulated from their environment, for example, an adjacent battery cell, module or battery casing. So far, self-adhesive films or heat shrink tubing are used for electrical insulation. When using films, however, there is the disadvantage that overlaps of the adhesive tape are necessary at the edges in order to isolate them. Shrink tubing also covers the corners and edges only poorly. This problem occurs especially in the isolation of the first and last cell in the battery module where the adapter plates of the
mechanischen Fixierung anliegen müssen, auf, da Schrumpfschläuche und mechanical fixation must lie on, since shrink tubing and
Klebebänder erfahrungsgemäß sehr schnell im Bereich der Kanten beschädigt werden, und nur eine ungenügende Kantenabdeckung bieten. Erfindungsgemäß wird deshalb ein Halbteil aus einem elektrisch isolierenden Material zwischen der Adapterplatte und den äußeren Batteriezellen angeordnet. Das Halbteil übergreift dabei die umlaufenden Seitenkanten der anliegenden äußeren Batteriezelle. Adhesive tapes are experienced to be damaged very quickly in the area of the edges, and only provide an insufficient edge coverage. Therefore, according to the invention, a half part of an electrically insulating material is arranged between the adapter plate and the outer battery cells. The half part engages over the circumferential side edges of the adjacent outer battery cell.
