Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Batterieeinheit mit einer Mehrzahl von zylindrischen Einzelzellen, wobei die zylindrischen Einzelzellen in einem Zellenblock in mehreren Reihen parallel nebeneinander angeordnet sind und der Zellenblock in ein Gehäuse einsetzbar ist, anzugeben.Of the Invention is based on the object, an improved battery unit with a plurality of cylindrical single cells, wherein the cylindrical Single cells in a cell block in several rows parallel next to each other are arranged and the cell block can be used in a housing is to indicate.
Die Aufgabe wird erfindungsgemäß durch eine Anordnung gelöst, welche die im Anspruch 1 angegebenen Merkmale aufweist.The Object is achieved by an arrangement having dissolved, which has 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.
An den seitlichen Randflächen des Zellenblocks, also an den Randflächen, die parallel zur Achse der zylindrischen Einzelzellen liegen, sind Kraftverteilelemente angeordnet. Die Kraftverteilelemente liegen jeweils mit ihrer nach innen gerichteten Seite formformschlüssig an den sie berührenden Einzelzellen an. An der gegenüberliegenden Seite entsprechen die Kraftverteilelemente der Form des Gehäuses, in welches der Zellenblock mit den Kraftverteilelementen eingesetzt wird. Die Höhe der Kraftverteilelemente ist geringer als die Höhe der zylindrischen Einzelzellen.At the lateral edge surfaces of the cell block, ie to the Edge surfaces parallel to the axis of the cylindrical single cells lie, force distribution elements are arranged. The force distribution elements are each form-fitting with their inwardly directed side at the individual cells touching them. At the opposite Side, the force distribution elements correspond to the shape of the housing, in which the cell block is used with the force distribution elements becomes. The height of the force distribution elements is less than the height of the cylindrical single cells.
Damit wird eine Batterieeinheit geschaffen, die sich durch eine hohe Stabilität bei einem Crash auszeichnet, ohne dass Bauraum und Gewicht nennenswert vergrößert werden. Dies wird dadurch erreicht, dass die Batterieeinheit vorrangig in Richtung der Crashkräfte verstärkt wird. Mit den Kraftverteilelementen wird das Batteriesystem auf geringstem Bauraum unter Einbeziehung der Stabilität der Einzelzellen und unter Beibehaltung eines leichten Gehäuses, das für sich betrachtet einem Crash nicht standhält, crashsicher gestaltet. Die Durchleitung der Kraft erfolgt im Crashfall von einem Zellenblockrand über ein Kraftverteilelement und von Zelle zu Zelle bis zum gegenüberliegenden Zellenblockrand. Dort wird die Kraft wieder von einem weiteren Kraftverteilelement aufgenommen und an das Gehäuse abgegeben. Das Gehäuse stützt sich an geeigneten Fahrzeugteilen ab. Damit ist eine bauraumoptimierte Batterieauslegung möglich, ohne schwere und Bauraum verbrauchende Gehäuseverstärkungen verwenden zu müssen.In order to a battery unit is created, which is characterized by a high stability in a crash, without the space and weight worth mentioning be enlarged. This is achieved by that the battery unit primarily in the direction of crash forces is reinforced. With the force distribution elements is the Battery system in the smallest space including the stability of the single cells and while maintaining a lightweight housing, that does not stand up to a crash on its own, designed crash-proof. The passage of the force takes place in the event of a crash from a cell block edge via a force distribution element and from cell to cell to the opposite cell block edge. There, the power is again from another force distribution element taken and delivered to the housing. The housing is based on suitable vehicle parts. This is a space-optimized battery design possible, without heavy and space-consuming housing reinforcements to use.
Eine vorteilhafte Ausführung sieht vor, dass die Höhe der Kraftverteilelemente 40 bis 60%, vorzugsweise 50%, der Höhe der zylindrischen Einzelzellen beträgt. Im Crashfall werden die im Notfall weitgehend querkraftfreien Batteriezellen durch das Kraftverteilelement am Randbereich des Zellenblocks mit der durch das Gehäuse eingeleiteten Kräfte großflächig im mittleren Bereich (über ca. 50% der Zellhöhe) belastet.A advantageous embodiment provides that the height the force distribution elements 40 to 60%, preferably 50%, of the height the cylindrical single cells is. In the event of a crash the emergency battery cells largely free of lateral forces in an emergency by the force distribution element at the edge of the cell block with the through the housing introduced forces over a large area in the middle Area (over about 50% of the cell height) charged.
Vorzugsweise sind die Kraftverteilungselemente in der Mitte der Zellhöhe angeordnet. Die Einleitung der Crashkräfte in dem mittleren Bereich der Zellen ermöglicht es, die relativ verformungssteifen Kopf- und Bodenbereiche lastfrei zu halten, da sich hier Sicherheitseinrichtungen (z. B. Ventingöffnung) oder Steuerungselektronik bzw. Kühlplatten befinden können. Diese Elemente können auch im Rahmen des Gesamtzellenblocks verschoben werden.Preferably, the force distribution elements are arranged in the middle of the cell height. The initiation of the crash forces in the central region of the cells makes it possible to keep the relatively deformation-resistant head and bottom areas free of load since here safety devices (eg Ventingöffnung) or control electronics or cooling plates can be located. These elements can also be moved within the frame of the total cell block.
Bei einer weiteren vorteilhaften Ausgestaltung ist der Zellenblock quaderförmig ausgebildet, wobei an allen vier Seiten des Zellenblocks Kraftverteilelemente angeordnet sind. Damit können Crashkräfte in mehreren Richtungen aufgenommen werden.at In a further advantageous embodiment, the cell block is cuboidal formed, wherein on all four sides of the cell block Kraftverteilelemente are arranged. This allows crash forces in several Directions to be included.
Ferner ist es möglich, dass die zylindrischen Einzelzellen an ihrer Kopfseite elektrische Anschlüsse aufweisen, die durch eine Abdeckplatte geführt sind, wobei die elektrischen Anschlüsse mittels Schienen außerhalb der Abdeckplatte elektrisch verbunden sind, vorzugsweise in einer Reihenschaltung. Damit wird eine stabile und crashsichere Anordnung der elektrischen Anschlüsse gewährleistet.Further is it possible for the cylindrical single cells to their head end have electrical connections through a cover plate are guided, wherein the electrical Connections by means of rails outside the cover plate are electrically connected, preferably in a series circuit. This is a stable and crash-proof arrangement of the electrical Guaranteed connections.
Eine weitere vorteilhafte Ausgestaltung sieht vor, dass die Abdeckplatte eine Kühleinrichtung einhält, wobei ein Kühlmittel durch einen Kühlmittelzufluss der Abdeckplatte zugeführt wird und durch einen Kühlmittelabfluss die Abdeckplatte wieder verlässt. Die Verwendung einer Abdeckplatte mit Kühleinrichtung ist vorteilhaft, da eine Kühlplatte eine einfache und kostengünstige Vorrichtung zur Temperierung der Batteriezellen darstellt. Durch die Integration elektrischer Bauelemente der Batterie in die Abdeckplatte kann diese gleichzeitig als Träger für elektrische Bauelemente der Batterie verwendet werden. Dadurch werden Bauraum und Herstellungskosten der Batterie eingespart.A Further advantageous embodiment provides that the cover plate a cooling device complies, wherein a coolant supplied by a coolant flow to the cover plate is and by a coolant drain the cover plate leaves again. The use of a cover plate with Cooling device is advantageous because a cooling plate a simple and inexpensive device for temperature control represents the battery cells. By integrating electrical Components of the battery in the cover plate can do this at the same time as a carrier for electrical components of the battery be used. As a result, space and manufacturing costs of Battery saved.
Eine weitere vorteilhafte Ausführung sieht vor, dass zwischen den Einzelzellen ein Zellzwischenelement angeordnet ist, dessen Form an die Form der Einzelzellen angepasst ist. Es ist auch möglich, dass mehrere Zellzwischenelemente angeordnet sind.A Another advantageous embodiment provides that between the individual cells, a cell intermediate element is arranged, whose Shape is adapted to the shape of the individual cells. It is also possible, that a plurality of cell intermediate elements are arranged.
Durch die Zellzwischenelemente erfolgt die Durchleitung der Kraft im Crashfall von Zelle zu Zelle bis zum Zellenblockrand. Dort wird die Kraft wieder von einem Kraftverteilelement aufgenommen und an das Gehäuse abgegeben. Dabei handelt es sich um weitgehend ”schwimmend” angeordnete Zellzwischenelemente, die auch geringe Relativbewegungen der Zellen gegeneinander aufnehmen können. Als Zusatzfunktionalität kann die Wärmeabfuhr über die Zellzwischenelemente zu einer Kühlplatte genutzt werden. Ein Vorteil der Zellzwischenelemente besteht auch in der Beibehaltung des Zellabstands unter Querkraft, d. h. die Zellen haben wenig Raum um sich zu verformen und somit beschädigt zu werden. Damit wird eine weitere Stabilitätserhöhung erreicht, da sowohl die inneren Batteriekomponenten, wie Batteriezellen oder gegebenenfalls Fixierteile, die Zellzwischenelemente sowie die Kraftverteilelemente zur Stabilitätserhöhung und damit zur Verbesserung der Crashsicherheit beitragen.By the cell intermediate elements is the passage of the force in the event of a crash from cell to cell to the cell block edge. There will be the power taken again by a force distribution element and to the housing issued. These are largely "floating" arranged Intermediate cells, which also have low relative movements of the cells can compete against each other. As additional functionality can heat dissipation through the cell intermediate elements be used to a cooling plate. An advantage of cell intermediate elements also exists in the retention of the cell distance under transverse force, d. H. The cells have little room to deform and thus to be damaged. This will be a further increase in stability achieved because both the internal battery components, such as battery cells or optionally fixing parts, the cell intermediate elements as well the force distribution elements to increase stability and thereby contribute to the improvement of crash safety.
Es ist zweckmäßig, dass die Höhenabmessungen der Zellzwischenelemente den Höhenabmessungen der Kraftverteilungselemente entsprechen. Damit wird eine hohe Sicherheit bei geringem Gewicht erreicht.It is appropriate that the height dimensions the cell intermediate elements the height dimensions of the force distribution elements correspond. This is a high security with low weight reached.
Ferner ist es möglich, dass als Zellzwischenelemente wellenförmig ausgebildete Wärmetauscherplatten verwendet werden, die sich formschlüssig an eine Reihe zylindrischer Einzelzellen anschließen und die von einem Temperiermedium durchströmte Wärmeaustauscherkanäle aufweisen. Bei dieser Ausführung können alle Einzelzellen gleich gekühlt werden. Wenn eine Temperaturdifferenz in den Einzelzellen entsteht, kann es leicht vorkommen, dass sich der Wirkungsgrad der Batterieeinheit verschlechtert. Bei einer Batterieeinheit, in welcher mehrere Reihen von Einzelzellen parallel nebeneinander angeordnet sind, ist es zweckmäßig, jede Einzelzelle auf gleiche Weise zu kühlen.Further it is possible that wavy as cell intermediate elements trained heat exchanger plates are used, the form fit to a series of cylindrical single cells connect and flowed through by a temperature control medium Have heat exchanger channels. In this version All single cells can be cooled equally. If a temperature difference arises in the individual cells, can It may easily happen that the efficiency of the battery unit deteriorated. In a battery unit in which several rows of single cells are arranged parallel to each other, it is appropriate, each single cell in the same way to cool.
Eine weitere Ausführungsform sieht vor, dass als Zellzwischenelemente Stäbe verwendet werden. Damit kann eine geringe Relativbewegung der Einzelzellen gegeneinander und eine gute Wärmeableitung zu einer Kühlplatte ermöglicht werden.A Another embodiment provides that as cell intermediate elements Rods are used. Thus, a small relative movement of the Single cells against each other and good heat dissipation be made possible to a cooling plate.
Es ist auch möglich, dass an den Zellzwischenelementen Abstandshalter angeordnet sind, mit denen die Höhenlage der Zellzwischenelemente fixiert wird.It it is also possible that at the cell intermediate elements spacers are arranged with which fixes the altitude of the cell intermediate elements becomes.
Vorteilhaft ist es, dass die Abstandshalter oben am Gehäusedeckel und/oder unten am Gehäuseboden anliegen. Damit kann mit einfachen Mitteln erreicht werden, dass die Zellzwischenelemente genau in ihrer vorbestimmten Höhenlage gehalten werden. Dies ermöglicht es eine optimale Position einzuhalten, bei der mit geringen Höhenabmessungen und damit geringem Gewicht eine maximale Crashsicherheit erreicht wird.Advantageous it is that the spacers on top of the housing cover and / or rest down on the bottom of the case. This can be done with simple Means can be achieved that the cell intermediate elements exactly in be held at their predetermined altitude. this makes possible to maintain it an optimal position, with low height dimensions and thus low weight achieves maximum crash safety becomes.
