Description
Die Erfindung betrifft einen Zellblock für eine Batterie mit einer Mehrzahl von elektrisch seriell und/oder parallel miteinander verschalteten Einzelzellen.The invention relates to a cell block for a battery having a plurality of electrically connected in series and / or parallel individual cells.
Batterien, insbesondere Hochvolt-Batterien für Fahrzeuganwendungen bestehen aus einer Anzahl von elektrisch seriell und/oder parallel miteinander verschalteten Einzelzellen. Die Einzelzellen sind zu Zellblöcken zusammengefasst, die jeweils eine vorgegebene Anzahl von Einzelzellen, die hintereinander angeordnet sind, deren mechanische Fixierung, Kontaktierung und Vorrichtung zum Temperieren der Einzelzellen umfassen. Flachzellen, wie z. B. Pouchzellen und Hartschalenzellen, sind mittels Halterahmen fixierbar, die eine Rahmenform oder eine Schalenform aufweisen. Diese Halterahmen fixieren die Einzelzellen im Wesentlichen durch Kraftschluss, wenn der Zellblock mittels Spannelementen, wie z. B. Zuganker, Gewindestäbe, Schrauben und/oder Spannbänder, und Druckbrillen axial verpresst ist. Die elektrische Verschaltung der Einzelzellen erfolgt direkt über die Verpressung, Verschraubung und/oder Verschweißung von Zellpolen zu verschaltender Einzelzellen. Alternativ dazu sind die Zellpole mittels Zellverbindern verbunden, die mit den Zellpolen verpresst, verschraubt und/oder verschweißt sind. An dem Zellblock ist eine Wärmeleitplatte zur Temperierung der Einzelzellen angeordnet. Dabei ist die Wärmeleitplatte direkt bzw. über eine elektrisch isolierende und Toleranz ausgleichende Wärmeleitfolie und/oder Vergussmasse oder indirekt über die Zellverbinder oder Kühlstäben und/oder Kühlblechen mit den Einzelzellen thermisch gekoppelt.Batteries, in particular high-voltage batteries for vehicle applications consist of a number of electrically connected in series and / or parallel single cells. The individual cells are combined into cell blocks, each comprising a predetermined number of individual cells, which are arranged one behind the other, their mechanical fixation, contacting and device for tempering the individual cells. Flat cells, such as. B. pouch cells and hard shell cells are fixed by means of holding frame having a frame shape or a shell shape. These holding frames fix the individual cells essentially by traction when the cell block by means of clamping elements, such as. As tie rods, threaded rods, screws and / or straps, and pressure goggles is axially compressed. The electrical interconnection of the individual cells takes place directly via the compression, screwing and / or welding of cell poles to be interconnected single cells. Alternatively, the cell poles are connected by means of cell connectors which are crimped, screwed and / or welded to the cell poles. At the cell block, a heat conducting plate for controlling the temperature of the individual cells is arranged. In this case, the heat conduction plate is thermally coupled directly or via an electrically insulating and tolerance compensating heat conduction foil and / or potting compound or indirectly via the cell connectors or cooling bars and / or cooling plates with the individual cells.
Der Erfindung liegt die Aufgabe zugrunde, einen gegenüber dem Stand der Technik verbesserten Zellblock für eine Batterie anzugeben.The invention has for its object to provide a comparison with the prior art improved cell block for a battery.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Zellblock für eine Batterie weist eine Mehrzahl von elektrisch seriell und/oder parallel miteinander verschalteten Einzelzellen auf. Erfindungsgemäß sind zumindest mehrere Zellreihen nebeneinander angeordnet, wobei zumindest nebeneinander angeordnete Einzelzellen benachbarter Zellreihen mit einer Temperiervorrichtung thermisch gekoppelt sind und/oder mit einem gemeinsamen mechanischen Fixierelement innerhalb des Zellblockes fixiert sind und/oder mit einer gemeinsamen Überwachungs- und/oder Steuerungseinheit gekoppelt sind und/oder mittels eines gemeinsamen elektrischen Kontaktierungselementes elektrisch verschaltet sind.A cell block for a battery has a plurality of electrically connected in series and / or parallel individual cells. According to the invention, at least a plurality of cell rows are arranged next to one another, wherein at least juxtaposed individual cells of adjacent rows of cells are thermally coupled to a tempering device and / or fixed with a common mechanical fixing within the cell block and / or are coupled to a common monitoring and / or control unit and / / or electrically connected by means of a common electrical contacting element.
Dadurch, dass der Zellblock aus mehreren Zellreihen gebildet ist und eine Anzahl erforderlicher Funktionsbauteile, wie beispielsweise die Temperiervorrichtung, für alle Einzelzellen des aus mehreren Zellreihen gebildeten Zellblockes vorgesehen ist, sind eine Teileanzahl des Zellblockes, Kosten eines Montageaufwandes und/oder ein Bauraumbedarf des Zellblockes verringert.Characterized in that the cell block is formed of several rows of cells and a number of required functional components, such as the tempering, is provided for all individual cells of the cell block formed from several rows of cells, a number of parts of the cell block, costs of assembly work and / or a space requirement of the cell block are reduced ,
Zusätzlich oder alternativ ist es auch möglich, mehrere Zellreihen hintereinander anzuordnen, wobei die Einzelzellen eines derart ausgebildeten Zellblockes ebenfalls mit einer Temperiervorrichtung thermisch gekoppelt sind und/oder mit einem gemeinsamen mechanischen Fixierelement innerhalb des Zellblockes fixiert sind und/oder mit einer gemeinsamen Überwachungs- und/oder Steuerungseinheit gekoppelt sind und/oder mittels eines gemeinsamen elektrischen Kontaktierungselementes elektrisch verschaltet sind.Additionally or alternatively, it is also possible to arrange a plurality of cell rows one behind the other, wherein the individual cells of a cell block formed in this way are also thermally coupled to a temperature control device and / or fixed with a common mechanical fixation element within the cell block and / or with a common monitoring and / or or control unit are coupled and / or electrically connected by means of a common electrical contacting element.
