Abstract
Description
Die Erfindung betrifft eine Batterie aus einem Stapel von Batterieeinzelzellen nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a battery of a stack of battery cells according to the closer defined in the preamble of
Aus dem allgemeinen Stand der Technik sind Batterien, und hier insbesondere Hochleistungs- bzw. Hochvoltbatterien bekannt, welche aus einem Stapel von Batterieeinzelzellen ausgebildet sind. Solche Batterien werden vorzugsweise als Traktionsbatterien in zumindest teilweise elektrisch angetriebenen Fahrzeugen, also Elektrofahrzeugen oder Hybridfahrzeugen, eingesetzt. Sie sind vorzugsweise auf Basis der Lithium-Ionen-Technologie ausgebildet.Batteries, and in particular high-performance or high-voltage batteries, which are formed from a stack of battery individual cells, are known from the general state of the art. Such batteries are preferably used as traction batteries in at least partially electrically driven vehicles, ie electric vehicles or hybrid vehicles. They are preferably formed on the basis of lithium-ion technology.
Die Batterieeinzelzellen des Stapels sind dabei im Wesentlichen flach bzw. quaderförmig ausgebildet und werden zu dem Stapel aufgestapelt und elektrisch miteinander kontaktiert. Hierdurch entsteht die Gesamtbatterie. Um den Stapel zu stabilisieren, wird dieser beispielsweise über Zuganker verspannt, sodass ein mechanisch stabiler Aufbau des Stapels entsteht. Die eingesetzten Zellen sind dabei im Wesentlichen prismatisch ausgebildet und können beispielsweise als bipolare Rahmenflachzellen innerhalb eines Zellrahmens aufgebaut sein oder sind vorzugsweise als sogenannte Coffeebag- oder Pouchzellen ausgebildet, bei denen der Elektrodenstapel zwischen Folien eingeschweißt wird, wobei dann typischerweise Zellrahmen so ausgebildet sind, dass sie die verschweißten Ränder der Folie zwischen sich einspannen und die mechanisch relativ labile Pouchzelle hierdurch stabilisieren.The individual battery cells of the stack are essentially flat or cuboid and are stacked up to the stack and electrically contacted with each other. This creates the total battery. To stabilize the stack, this is braced, for example via tie rods, so that a mechanically stable construction of the stack is formed. The cells used are essentially of prismatic design and can be constructed, for example, as bipolar frame flat cells within a cell frame or are preferably designed as so-called coffee bag or pouch cells, in which the electrode stack is welded between foils, in which case cell frames are typically designed such that they clamp the welded edges of the film between them and thereby stabilize the mechanically relatively unstable pouch cell.
Das Verspannen des Stapels der Batterieeinzelzellen über Zuganker ist beispielsweise in der
Der Nachteil dieses Aufbaus besteht darin, dass eine Vielzahl von einzelnen Bauteilen wie beispielsweise Zwischenrahmen, Spannelemente und dergleichen notwendig sind, um die Batterieeinzelzellen untereinander in dem Stapel zu fixieren und miteinander zu verspannen bzw. verspannt in ein Stapelgehäuse einzubringen. Die Vielzahl von Teilen macht den Aufbau entsprechend komplex, aufwändig und teuer. Insbesondere die Spannanker, welche aus Stabilitätsgründen typischerweise in Form von Stahlbauteilen realisiert werden müssen, machen den Aufbau der Batterie darüber hinaus vergleichsweise schwer, was insbesondere für den oben angesprochenen mobilen Einsatz in Kraftfahrzeugen höchst unerwünscht ist.The disadvantage of this structure is that a plurality of individual components such as intermediate frames, clamping elements and the like are necessary to fix the battery cells with each other in the stack and to brace each other or braced in a stack housing. The variety of parts makes the structure correspondingly complex, complex and expensive. In particular, the tension anchors, which typically have to be realized in the form of steel components for reasons of stability, make the structure of the battery moreover relatively difficult, which is highly undesirable, in particular for the above-mentioned mobile use in motor vehicles.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Batterie anzugeben, welche diese Nachteile vermeidet und welche einen einfachen, schnell zu montierenden, zuverlässigen und sicheren Aufbau gewährleistet, welcher darüber hinaus außerordentlich einfach und leicht realisiert werden kann.The object of the present invention is therefore to provide a battery which avoids these disadvantages and which ensures a simple, fast to assemble, reliable and safe construction, which in addition can be extremely simple and easy to implement.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale im kennzeichnenden Teil des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Batterie ergeben sich aus den hiervon abhängigen Unteransprüchen.According to the invention this object is achieved by the features in the characterizing part of
Bei der erfindungsgemäß aufgebauten Batterie wird zwischen den Batterieeinzelzellen in dem Stapel jeweils eine Luftkammerfolie angeordnet. Eine solche Luftkammerfolie, welche auch als Blasenfolie bezeichnet wird, besteht aus wenigstens zwei Folienschichten, welche zwischen den Folienschichten angeordnete Luftkammern aufweisen. Die Folien werden beispielsweise zur Verpackung von empfindlichen Materialien eingesetzt. Sie weisen in diesem Fall eine gleichmäßige Verteilung von typischerweise runden einzelnen Luftkammern bzw. Blasen auf. Mit derartigen Folien zwischen den Batterieeinzelzellen lässt sich nun ein Aufbau realisieren, welcher sehr flexibel ist und durch die Elastizität der Luftkammerfolien einen Toleranzausgleich sowie einen Längenausgleich im Betrieb ermöglicht, wenn Teile sich stark erwärmen oder sich bei Lade- und Entladevorgängen ausdehnen und zusammenziehen. Der Aufbau ist dabei außerordentlich einfach in der Montage und darüber hinaus sehr leicht und kostengünstig.In the case of the battery constructed according to the invention, in each case one air chamber foil is arranged between the battery individual cells in the stack. Such an air-chamber film, which is also referred to as a bubble film, consists of at least two film layers, which have air chambers arranged between the film layers. The films are used, for example, for packaging sensitive materials. In this case, they have a uniform distribution of typically round individual air chambers or bubbles. With such films between the battery cells now a structure can be realized, which is very flexible and allows the elasticity of the air chamber films tolerance compensation and length compensation during operation when parts heat up strongly or expand and contract during loading and unloading. The structure is extremely easy to install and also very easy and inexpensive.
In einer bevorzugten Weiterbildung der erfindungsgemäßen Idee ist der Stapel aus Batterieeinzelzellen und Luftkammerfolien dabei in einem Stapelgehäuse angeordnet. Ein solches Stapelgehäuse gibt dem Stapel aus Batterieeinzelzellen und Luftkammerfolien eine gewisse Stabilität. So kann beispielsweise der Stapel aufgestapelt und unter leichter Vorspannung in das Stapelgehäuse eingebracht werden. Die Vorspannung hält dann sowohl die Luftkammerfolien als auch die Batterieeinzelzellen in dem Stapel sicher und zuverlässig an ihrer Position.In a preferred development of the idea according to the invention, the stack of individual battery cells and air chamber foils is arranged in a stack housing. Such a stack housing gives a certain stability to the stack of battery individual cells and air chamber foils. For example, the stack can be stacked and placed under slight bias in the stack housing. The bias then holds both the air chamber foils and the battery cells in the stack safely and reliably in place.
In einer besonders bevorzugten Weiterbildung der erfindungsgemäßen Batterie ist es dabei vorgesehen, dass die Batterieeinzelzellen einen Elektrodenstapel aufweisen, welcher zwischen Folien eingeschweißt ausgebildet ist. Insbesondere bei einem solchen Aufbau der Batterieeinzelzellen als sogenannte Coffeebag- oder Pouchzellen ist der Aufbau mit zwischen den Batterieeinzelzellen angeordneten Luftkammerfolien besonders effizient, da hier durch Stapeln ein insgesamt sehr einfacher Aufbau entsteht, welcher auf zusätzliche Zwischenrahmen zur Halterung der Pouchzellen verzichten kann. Der Aufbau wird hierdurch sehr einfach, benötigt weniger zusätzliche Bauteile und wird entsprechend leicht.In a particularly preferred embodiment of the battery according to the invention it is provided that the battery individual cells have an electrode stack, which is formed between welded films. In particular, in such a construction of the individual battery cells as so-called Coffeebag- or Pouchzellen the structure with arranged between the battery cells Luftkammerfolien is particularly efficient, since here by stacking an overall very simple structure arises, which can dispense with additional intermediate frame for holding the Pouchzellen. The structure is thereby very simple, requires fewer additional components and is correspondingly light.
In einer besonders günstigen Weiterbildung hiervon ist es dabei vorgesehen, dass die Luftkammerfolie in den dem verschweißten Randbereich der Batterieeinzelzelle benachbarten Abschnitten flächig größere und dickere Luftkammern aufweist, als im Bereich ihrer mittigen Fläche. Eine solche an den Aufbau der Pouchzelle angepasste Ausgestaltung der Luftkammerfolie ermöglicht eine Fixierung der Luftkammerfolie und der Pouchzelle quer zur Stapelrichtung gegeneinander, da über größere und dickere Luftkammern im Randbereich, welche mit den verschweißten Randbereichen der Folien der Pouchzelle korrespondieren, und entsprechend kleinere Luftpolster im Bereich der Fläche, in der bei der Pouchzelle die Elektrodenstapel angeordnet sind, eine Fixierung der Pouchzelle und der Luftkammerfolie gegeneinander erfolgen kann. Hierdurch entsteht ein hinsichtlich mechanischer Verschiebung stabiler Stapel, welcher dann unter leichter Vorspannung in ein Stapelgehäuse, welches vorzugsweise als Spritzgussgehäuse ausgebildet ist, eingebracht werden kann. Hier entsteht alles in allem ein sehr einfacher Aufbau, welcher sich schnell und effizient montieren lässt und welcher bei sehr guten Elastizitätseigenschaften zum Toleranzausgleich und zum Ausgleich von thermischen Längenänderungen außerordentlich leicht realisiert werden kann. Im Vergleich zu einem herkömmlich aufgebauten Zellenstapel einer Batterie aus Pouchzellen mit Zwischenrahmen und metallischen Zugankern lassen sich beispielsweise bei einem Stapel aus zweiunddreißig Batterieeinzelzellen bis zu 7 kg an Gewicht einsparen.In a particularly favorable development of this, it is provided that the air chamber film in the welded edge region of the battery single cell adjacent sections has larger and thicker air chambers, as in the region of its central surface. Such a configuration of the air chamber foil which is adapted to the construction of the pouch cell makes it possible to fix the air chamber foil and the pouch cell transversely to the stacking direction, since larger and thicker air chambers in the edge region, which correspond to the welded edge regions of the pouch cell foils, and correspondingly smaller air pockets in the region the surface in which the electrode stacks are arranged in the pouch cell, a fixation of the pouch cell and the air chamber foil can be made against each other. This results in a stack which is stable with respect to mechanical displacement and which can then be introduced under slight prestressing into a stacked housing, which is preferably designed as an injection-molded housing. All in all, this results in a very simple structure, which can be assembled quickly and efficiently and which can be extremely easily realized with very good elasticity properties for tolerance compensation and for compensation of thermal length changes. In comparison with a conventionally constructed cell stack of a battery of pouch cells with intermediate frames and metallic tie rods, for example, a stack of thirty-two individual battery cells can save up to 7 kg in weight.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Batterie ergeben sich aus den restlichen abhängigen Ansprüchen und werden anhand des Ausführungsbeispiels deutlich, welches nachfolgend unter Bezugnahme auf die Figuren näher beschrieben wird.Further advantageous embodiments of the battery according to the invention will become apparent from the remaining dependent claims and will be apparent from the embodiment, which will be described below with reference to the figures.
