Description
Die Erfindung betrifft einen Zellrahmen mit zumindest einer Ausnehmung zur Aufnahme von zumindest einer Batteriezelle, einen Zellstapel mit zumindest einem Zellrahmen sowie dessen Verwendung.The invention relates to a cell frame with at least one recess for receiving at least one battery cell, a cell stack with at least one cell frame and its use.
Die insbesondere in der Automobilindustrie zum Einsatz kommenden wiederaufladbaren Batterien bestehen üblicherweise aus einer Vielzahl von Batteriezellen, die im Zellstapel zusammengefasst und miteinander verschaltet sind. Hierbei werden die verschiedensten Zellentypen zu derartigen Zellenstapeln oder auch Modulen zusammengefügt. Besonders von Interesse sind hierbei die sogenannten ”Pouch-Zellen”, die eine gute Leistungs- und Energiedichte aufweisen, sowie aufgrund ihres Folienaufbaus besonders gewichteinsparend und günstig in der Herstellung sind. Allerdings sind diese Pouch-Zellen oder Folienzellen empfindlich hinsichtlich mechanischer Beanspruchung und besitzen die Eigenschaft, während des Lade- und Entladezyklus sowie im Betrieb auf Grund der dabei ablaufenden Zellreaktionen ihre Dicke zu verändern, die innerhalb eines Zellstapels auszugleichen ist. Weiters weist die Außengeometrie derartiger Pouch-Zellen häufig eine sehr große Fertigungstoleranz auf, wodurch eine definierte Aufnahme in einer Halterung erschwert wird.The rechargeable batteries used in particular in the automotive industry usually consist of a multiplicity of battery cells, which are combined in the cell stack and connected to one another. Here, the most diverse cell types are assembled into such cell stacks or modules. Of particular interest here are the so-called "pouch cells", which have a good power and energy density, and are particularly weight-saving and inexpensive to manufacture due to their film structure. However, these pouch cells or foil cells are sensitive to mechanical stress and have the property during the charging and discharging cycle as well as in operation due to the ongoing cell reactions to change their thickness, which is to be compensated within a cell stack. Furthermore, the outer geometry of such Pouch cells often has a very large manufacturing tolerance, whereby a defined recording in a holder is difficult.
Üblicherweise werden derartige Zellen in einem Zellrahmen fixiert, und diese Rahmen zu Zellstapeln aneinander gereiht. Im Stand der Technik sind zahlreiche unterschiedliche Systeme bekannt geworden, die die Anordnung der Zelle innerhalb eines Zellrahmens behandeln.Usually, such cells are fixed in a cell frame and these frames are stacked into cell stacks. Numerous different systems have become known in the art which deal with the arrangement of the cell within a cell frame.

Es ist daher Aufgabe der Erfindung, einen Zellrahmen der eingangs erwähnten Art zur Verfügung zu stellen, der besonders sicher im Betrieb ist und auf einfache Weise und kostengünstig herzustellen ist.It is therefore an object of the invention to provide a cell frame of the type mentioned above, which is particularly safe in operation and is easy to manufacture and inexpensive.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zumindest ein, vorzugsweise zwei oder mehr Positionierelemente vorgesehen sind, über die die zumindest eine Batteriezelle in der zumindest einen Ausnehmung des Zellrahmens positionierbar und fixierbar ist. Hierbei steht das Zellengehäuse der zumindest einen Batteriezelle in der zumindest einen Ausnehmung des erfindungsgemäßen Zellrahmens über zumindest ein Positionierelement mit diesem in Verbindung. Diese punktuelle bzw. abschnittsweise Befestigung der Batteriezelle innerhalb der Ausnehmung des Zellrahmens erlaubt eine besonders flexible Anordnung der zumindest einen Batteriezelle, sodass die Batteriezelle trotz der im Betrieb auftretenden Dicken- und gegebenenfalls Längenänderungen sicher innerhalb des Zellrahmens angeordnet ist.This object is achieved in that at least one, preferably two or more positioning elements are provided, via which the at least one battery cell in the at least one recess of the cell frame can be positioned and fixed. In this case, the cell housing of the at least one battery cell is in the at least one recess of the cell frame according to the invention via at least one positioning element with this. This selective or sectional attachment of the battery cell within the recess of the cell frame allows a particularly flexible arrangement of the at least one battery cell, so that the battery cell despite the thickness and possibly length changes occurring during operation is securely disposed within the cell frame.
Unter Zellengehäuse wird im Rahmen dieser Offenbarung die Hülle der Batteriezelle verstanden, unabhängig von deren Beschaffenheit; das Zellengehäuse kann hierbei starr, flexibel oder semirigide ausgeführt sein. Bevorzugt ist hierbei, dass das Zellengehäuse im Wesentlichen prismatisch mit vier Eckbereichen ausgeführt ist, wobei erfindungsgemäß an zumindest zwei, vorzugsweise vier Eckbereichen jeweils ein Positionierelement eingreift. Hierbei wird die Batteriezelle über ihr Zellengehäuse in diesen Eckbereichen über das erfindungsgemäße Positionierelement mit dem Zellrahmen verbunden. Alternativ oder zusätzlich hierzu kann vorgesehen sein, dass an einer Seite, vorzugsweise an zwei, drei oder vier Seiten des Zellengehäuses je ein Positionierelement eingreift. Auf diese Weise ist eine flexible Anordnung der Batteriezelle innerhalb der Ausnehmung des Zellrahmens realisiert.Under cell housing is understood in the context of this disclosure, the shell of the battery cell, regardless of their nature; The cell housing can be made rigid, flexible or semirigid. In this case, it is preferred that the cell housing is designed substantially prismatically with four corner regions, wherein according to the invention at least two, preferably four corner regions each engage a positioning element. In this case, the battery cell is connected via its cell housing in these corner regions via the positioning element according to the invention with the cell frame. Alternatively or additionally, it can be provided that engages on one side, preferably on two, three or four sides of the cell housing depending on a positioning element. In this way, a flexible arrangement of the battery cell is realized within the recess of the cell frame.
Die Befestigung des Positionierelements an dem Zellengehäuse der Batteriezelle bzw. an dem Zellrahmen kann auf unterschiedlichste Art und Weise erfolgen. In einer besonders bevorzugten Ausführung der Erfindung steht das zumindest eine Positionierelement als separater Teil über zumindest eine Clips-, Schraub-, Klebe-, Schweiß-, Löt-, und/oder Nietverbindung mit dem Zellrahmen in Verbindung.The attachment of the positioning of the cell housing of the battery cell or to the cell frame can be done in various ways. In a particularly preferred embodiment of the invention, the at least one positioning element is connected to the cell frame as a separate part via at least one clip, screw, adhesive, welding, soldering and / or riveting connection.
Alternativ hierzu ist vorgesehen, dass das zumindest eine Positionierelement integraler Bestandteil des Zellrahmens ist. Damit ist das zumindest eine Positionierelement unverlierbar bzw. nicht-herausnehmbar in dem Zellrahmen angeordnet.Alternatively, it is provided that the at least one positioning element is an integral part of the cell frame. Thus, the at least one positioning element is arranged captive or non-removable in the cell frame.
Hierbei besonders bevorzugt vorgesehen, dass das zumindest eine Positionierelement formschlüssig in dem Zellrahmen aufgenommen ist, und diesen nicht überragt, sodass beim Zusammenfügen der einzelnen Zellrahmen zu Zellstapel die einzelnen Positionierelemente einander nicht in ihrer Wirkweise beeinflussen.In this case, it is particularly preferably provided that the at least one positioning element is received in a form-fitting manner in the cell frame, and does not project beyond it, so that when the individual cell frames are assembled into cell stacks, the individual positioning elements do not influence one another in their mode of action.
Die flexible Anordnung des Zellengehäuses innerhalb des Zellrahmens wird weiter dadurch verbessert, dass das zumindest eine Positionierelement aus elastischem Material gefertigt ist.The flexible arrangement of the cell housing within the cell frame is further characterized improves that the at least one positioning element is made of elastic material.
Alternativ dazu kann vorgesehen sein, dass das zumindest eine Positionierelement über ein Verstellmittel mit dem Zellrahmen in Verbindung steht. Damit kann je nach eingesetztem Zelltyp die Kraft, mit der die Batteriezelle in ihrer Position im Zellrahmen gehalten wird, eingestellt werden. So ist besonders bevorzugt vorgesehen, dass das zumindest eine Positionierelement über einen vorzugsweise aus Kunststoff gefertigten Positionierelementkörper verfügt, in dem das Verstellmittel anordenbar ist. Dieses Verstellmittel ist beispielsweise als Schraubkörper ausgebildet, der in den Positionierelementkörper hinein- oder herausgeschraubt wird. Durch diese Schraubbewegung wird eine Druckkraft auf das Zellengehäuse der zumindest einen Batteriezelle ausgeübt, die sie damit in der Ausnehmung des Zellrahmens in Position hält.Alternatively, it may be provided that the at least one positioning element is connected to the cell frame via an adjusting means. Thus, depending on the type of cell used, the force with which the battery cell is held in its position in the cell frame can be adjusted. It is thus particularly preferably provided that the at least one positioning element has a positioning element body, preferably made of plastic, in which the adjusting means can be arranged. This adjusting means is designed, for example, as a screw body which is screwed into or out of the positioning element body. By this screwing a compressive force is exerted on the cell housing of the at least one battery cell, which keeps them in position in the recess of the cell frame.
Um diese Verstellbarkeit und die daraus resultierende Spannung auf einfache Weise realisieren zu können, ist in einer bevorzugten Ausführung der Erfindung das Verstellmittel über eine Öffnung im Zellrahmen zugänglich.To be able to realize this adjustability and the resulting voltage in a simple manner, in a preferred embodiment of the invention, the adjusting means via an opening in the cell frame is accessible.
Die vorliegende Erfindung hat den Vorteil, dass der zum Einsatz kommende Zellrahmen einstückig und damit auch günstig hergestellt werden kann, hierbei ist besonders bevorzugt vorgesehen, dass der Zellrahmen aus einer metallischen Legierung oder aus einem Kunststoff, bevorzugterweise aus einem faserverstärktem Kunststoff, einem Polymer/Elastomer-Verbund, und/oder aus einem Faser-Verbund-Werkstoff gefertigt ist.The present invention has the advantage that the cell frame used can be produced in one piece and thus also favorably, in which case it is particularly preferred that the cell frame is made of a metallic alloy or of a plastic, preferably of a fiber-reinforced plastic, a polymer / elastomer Composite, and / or is made of a fiber composite material.
Die Erfindung wird des Weiteren durch einen Zellstapel mit zumindest zwei Batteriezellen gelöst, wobei in dem Zellrahmen zumindest eine Batteriezelle, vorzugsweise zwei oder mehr Batteriezellen angeordnet sind. Die Batteriezellen können hierbei parallel oder seriell verschaltet sein.The invention is further solved by a cell stack having at least two battery cells, wherein in the cell frame at least one battery cell, preferably two or more battery cells are arranged. The battery cells can be connected in parallel or in series.
In einer weiteren Ausführung der Erfindung ist zwischen zwei benachbarten Batteriezellen zumindest ein Trennelement angeordnet, das vorzugsweise als Dickenausgleichselement und/oder als thermisches und/oder elektrisches Isolationselement oder als thermisch leitendes Element zur Kühlung der Zellen ausgeführt ist.In a further embodiment of the invention, at least one separating element is arranged between two adjacent battery cells, which is preferably designed as a thickness compensation element and / or as a thermal and / or electrical insulation element or as a thermally conductive element for cooling the cells.
Um eine Fixierung dieses Trennelements im erfindungsgemäßen Zellrahmen zu erhalten, ist besonders bevorzugt das zumindest eine Trennelement in einer Aufnahme des Zellrahmens aufgenommen.To obtain a fixation of this separating element in the cell frame according to the invention, the at least one separating element is particularly preferably received in a receptacle of the cell frame.
In einer weiteren Ausführung der Erfindung ist vorgesehen, dass der Zellstapel aus zumindest zwei Zellrahmen mit darin angeordneten Batteriezellen besteht, wobei die Zellrahmen miteinander beispielsweise verklebt, verclipst, verschraubt und/oder zwischen zwei Endplatten verspannt sind. Um die mechanische Stabilität weiter zu verbessern, ist in einer weiteren Ausführung der Erfindung vorgesehen, dass zumindest zwei benachbarte Batteriezellen zusätzlich oder alternativ hierzu miteinander verklebt sind.In a further embodiment of the invention, it is provided that the cell stack consists of at least two cell frames with battery cells arranged therein, the cell frames being glued, clipped, screwed and / or braced between two end plates, for example. In order to further improve the mechanical stability, it is provided in a further embodiment of the invention that at least two adjacent battery cells are additionally or alternatively adhesively bonded together.
Im Betrieb können Batteriezellen Wärme entwickeln, die sich negativ auf die Lebensdauer der Zelle auswirkt. Daher ist in einer besonders bevorzugten Ausführung der Erfindung vorgesehen, dass zumindest zwei benachbarte Batteriezellen beabstandet zueinander angeordnet sind, wobei der so gebildete Freiraum der Kühlung der Batteriezellen dient. Damit wird eine thermische Konditionierung der Zellen ermöglicht.In operation, battery cells can develop heat that negatively impacts the life of the cell. Therefore, in a particularly preferred embodiment of the invention, it is provided that at least two adjacent battery cells are arranged at a distance from one another, the free space thus formed serving to cool the battery cells. This allows thermal conditioning of the cells.
Der erfindungsgemäße Zellstapel hat sich insbesondere bei der Verwendung in einem Antriebssystem für Kraftfahrzeuge bewährt.The cell stack according to the invention has proved to be particularly useful when used in a drive system for motor vehicles.
