Abstract
Description
Die Erfindung betrifft eine Traktionsbatterie für ein elektrisch betriebenes Fahrzeug nach dem Oberbegriff des Patentanspruches 1.The invention relates to a traction battery for an electrically operated vehicle according to the preamble of claim 1.
Die Fahrzeugbatterie eines elektrisch betriebenen Fahrzeugs kann aus einer Anzahl von Batteriemodulen bestehen. Die Batteriemodule sind in einem oder mehreren Batteriekästen an der Fahrzeugkarosserie montiert, zum Beispiel unterhalb einer Rücksitzbank eines Fahrzeuges. In jedem der Batteriemodule sind Batteriezellen zu einem Zellenverbund zusammengefasst. Zur Bildung des Batteriezellenverbundes sind die Batteriezellen in einer vorgegebenen Stapelrichtung eng aneinander gestapelt. Die Fahrzeugbatterie ist dabei so anzuordnen, dass im Crashfall eine Beschädigung der Batteriezellen zuverlässig verhindert ist. Eine solche Beschädigung könnte nämlich zu einem inneren Kurzschluss der Fahrzeugbatterie führen.The vehicle battery of an electrically powered vehicle may consist of a number of battery modules. The battery modules are mounted in one or more battery boxes on the vehicle body, for example below a rear seat of a vehicle. In each of the battery modules, battery cells are combined into a cell network. To form the battery cell network, the battery cells are stacked tightly in a predetermined stacking direction. The vehicle battery is to be arranged so that damage to the battery cells is reliably prevented in the event of a crash. Namely, such damage could lead to an internal short circuit of the vehicle battery.

Die Aufgabe der Erfindung besteht darin, eine Traktionsbatterie für ein elektrisch betriebenes Fahrzeug bereitzustellen, bei der der erforderliche Bauraum reduziert ist und gleichzeitig auch im Crashfall eine ausreichend große Energieabsorptionsfähigkeit bereitgestellt ist.The object of the invention is to provide a traction battery for an electrically operated vehicle, in which the required space is reduced and at the same time a sufficiently large energy absorption capacity is provided in the event of a crash.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims.
Die Erfindung beruht auf dem Sachverhalt, dass die zum Schutz der Batteriezellen vorgesehene bauteilsteife Tragstruktur der aus der
Die Batteriezellen des Batteriemoduls sind bevorzugt baugleich ausgeführt. Dabei kann jede der Batteriezellen langgestreckt mit Längsseiten sowie mit in der Längserstreckungsrichtung einander gegenüberliegenden Stirnseiten ausgebildet sein. Die Grundform der Batteriezellen kann dabei quaderförmig oder auch zylinderförmig sein. Bei quaderförmig ausgeführten Batteriezellen können diese einander gegenüberliegende flache Längsseiten sowie umlaufende schmale Stirnseiten aufweisen. Bevorzugt sind die zum Beispiel quaderförmigen Batteriezellen mit den einander zugewandten Längsseiten aneinander gereiht in einer Batteriezellen-Reihe gestapelt.The battery cells of the battery module are preferably designed identical. In this case, each of the battery cells can be elongated with longitudinal sides and also with opposite end faces in the longitudinal direction of extension. The basic form of the battery cells can be cuboid or cylindrical. In parallelepiped running battery cells, these may have opposite flat longitudinal sides and circumferential narrow end faces. Preferably, the cuboid battery cells, for example, are stacked together with the longitudinal sides facing one another in a row of battery cells.
Je nach Ausführung des Außengehäuses der Traktionsbatterie können die Batteriezellen dabei nicht unmittelbar aneinander gereiht sein, sondern bevorzugt unter Zwischenlage von Zwischenwänden des Batteriegehäuses. Die Zwischenwände des Batteriegehäuses sind bevorzugt aus einem insbesondere elastisch nachgiebigen Material hergestellt, das im Crashfall bei einer Batteriezellen-Verlagerung unter Abbau von Deformationsenergie nachgibt.Depending on the design of the outer housing of the traction battery, the battery cells can not be placed directly next to each other, but preferably with the interposition of partitions of the battery case. The partitions of the battery case are preferably made of a particular elastically yielding material that yields in the event of a crash in a battery cell displacement with degradation of deformation energy.
In einer bevorzugten Ausführungsform können die Batteriezellen in der Batteriezellen-Reihe zueinander in ihrer Längserstreckungsrichtung längsversetzt sein. Das heißt, dass in der Stapelrichtung betrachtet jeweils aufeinanderfolgende Batteriezellen mit ihrem stirnseitigen Ende um einen Überstand das stirnseitige Ende der benachbarten Batteriezelle überragen. In diesem Fall bildet die Batteriezellen-Reihe seitlich außen eine Verzahnungsstruktur, bei der die seitlich außen liegenden Außenkanten der stirnseitigen Enden der Batteriezellen in einer gemeinsamen Ebene ausgerichtet sein können, die parallel zur Stapelrichtung ist. Zwischen den in der Stapelrichtung benachbarten Außenkante können Rücksprünge vorgesehen sein, die durch die Stirnwand einer Batteriezelle sowie durch das um den Überstand vorstehende stirnseitige Ende der benachbarten Batteriezelle begrenzt ist. Jede der Batteriezellen kann mit gleichem Stapelwinkel zur Stapelrichtung schräggestellt sein.In a preferred embodiment, the battery cells in the battery cell row can be offset longitudinally relative to each other in their longitudinal direction. That is to say, in the stacking direction, successive battery cells each have an overhang at their front end project beyond the front end of the adjacent battery cell. In this case, the battery cell row forms laterally on the outside a toothed structure, in which the laterally outer outer edges of the front ends of the battery cells can be aligned in a common plane, which is parallel to the stacking direction. Recesses may be provided between the outer edge adjacent in the stacking direction, which recess is bounded by the end wall of a battery cell and by the front end of the adjacent battery cell that projects around the projection. Each of the battery cells can be tilted at the same stack angle to the stacking direction.
In einer weiteren Ausführungsform kann zumindest eine zweite Batteriezellen-Reihe in dem Batteriemodul vorgesehen sein. Die Batteriezellen der zweiten Batteriezellen-Reihe können mit Bezug auf eine zur Stapelrichtung parallele Symmetrieachse spiegelsymmetrisch angeordnet sein. Bevorzugt können dabei die einander zugewandten stirnseitigen Batteriezellen-Enden formschlüssig ineinander verzahnt sein. Auf diese Weise bilden die ersten und zweiten Batteriezellen-Reihen ein Fischgrätenmuster, bei dem die Batterizellen der ersten und zweiten Reihe in besonders großer Packungsdichte bereitgestellt sind.In a further embodiment, at least one second battery cell row may be provided in the battery module. The battery cells of the second battery cell row can be arranged mirror-symmetrically with respect to an axis of symmetry parallel to the stacking direction. Preferably, the mutually facing end-side battery cell ends can be positively interlocked with each other. In this way, the first and second battery cell rows form a herringbone pattern, in which the battery cells of the first and second series are provided in a particularly large packing density.
Die Einbaulage der erfindungsgemäßen Traktionsbatterie kann so gewählt sein, dass sich im Crashfall eine Hauptbelastungsrichtung ergibt, bei der die unfallbedingte Aufprallkraft quer zur Stapelrichtung verläuft. In diesem Fall kann gewährleistet werden, dass sich die in der Stapelrichtung schräggestellten Batteriezellen aufgrund der einwirkenden Kraftkomponenten der Aufprallkraft in deren Längserstreckungsrichtung zueinander verschieben können und/oder zueinander verschwenken können. Diese crashbedingten Verlagerungen der Batteriezellen erfolgt dabei unter zumindest teilweisem Abbau von Deformationsenergie sowie unter Reduzierung der Batteriemodul-Breite um einen Deformationsweg.The mounting position of the traction battery according to the invention can be selected so that in the event of a crash results in a main load direction in which the accidental impact force extends transversely to the stacking direction. In this case, it can be ensured that the battery cells, which are inclined in the stacking direction, can shift relative to one another in the direction of their longitudinal extent due to the acting force components of the impact force and / or can pivot relative to one another. This crash-induced displacements of the battery cells is carried out under at least partial degradation of deformation energy and reducing the battery module width by a deformation path.
Das Batteriemodul kann zudem eine rahmenartig umlaufende Gehäusewand aufweisen, die die Batteriezellen einfasst. Die Gehäusewand ist dabei in Abkehr zum Stand der Technik nicht mehr bauteilsteif ausgeführt, sondern vielmehr – wie auch die bereits erwähnten Zwischenwände – aus einem bevorzugt elastisch nachgiebigen Material hergestellt, um eine unfallbedingte Krafteinleitung direkt in die Batteriezellen-Reihen zu ermöglichen.The battery module can also have a frame-like encircling housing wall which encloses the battery cells. In contrast to the prior art, the housing wall is no longer structurally rigid, but rather - as well as the already mentioned intermediate walls - made of a preferably elastically yielding material to allow an accidental introduction of force directly into the battery cell rows.
Bei einer zwei- oder mehrreihigen Anordnung der Batteriezellen bilden die in der Stapelrichtung jeweils endseitigen Batteriezellen eine pfeilförmige, spitz zulaufende Endseite sowie an der gegenüberliegenden Endseite eine in der Stapelrichtung zurückgesetzte pfeilförmige Aussparung. In dieser pfeilförmigen Aussparung können beispielhaft die Leistungselektronik der Traktionsbatterie und/oder andere Elektronik-Komponenten angeordnet werden.In the case of a two-row or multi-row arrangement of the battery cells, the battery cells in each case in the stacking direction form an arrow-shaped, pointed end side and, at the opposite end side, an arrow-shaped recess recessed in the stacking direction. In this arrow-shaped recess, the power electronics of the traction battery and / or other electronic components can be arranged by way of example.
Die umlaufende Gehäusewand kann polygonförmig ausgebildet sein, zum Beispiel sechseckförmig. Bevorzugt kann die Gehäusewand zwei mit Abstand gegenüberliegende parallel verlaufende Querwände aufweisen, die sich entlang der oben erwähnten Außenkanten der Batteriereihen bewegen können. Die beiden Querwände können über seitliche Abschlusswände miteinander verbunden sein, die pfeilförmig zusammenlaufen.The circumferential housing wall may be polygonal, for example hexagonal. Preferably, the housing wall may have two spaced apart parallel transverse walls which can move along the above-mentioned outer edges of the battery rows. The two transverse walls can be connected to each other via lateral end walls, which converge in an arrow shape.
Wie bereits oben erwähnt, können die Batteriezellen unter Zwischenlage von Zwischenwänden aneinander gestapelt sein. Die Zwischenwände können zusammen mit der umlaufenden Gehäusewand materialeinheitlich und einstückig ausgeführt sein.As already mentioned above, the battery cells can be stacked together with the interposition of intermediate walls. The partitions can be made of the same material and in one piece together with the encircling housing wall.
Die vorstehend erläuterten und/oder in den Unteransprüchen wiedergegebenen vorteilhaften Aus- und/oder Weiterbildungen der Erfindung können – außer zum Beispiel in den Fällen eindeutiger Abhängigkeiten oder unvereinbarer Alternativen – einzeln oder aber auch in beliebiger Kombination miteinander zur Anwendung kommen.The advantageous embodiments and / or further developments of the invention explained above and / or reproduced in the dependent claims can be used individually or else in any desired combination with one another, for example in the case of clear dependencies or incompatible alternatives.
Die Erfindung und ihre vorteilhaften Aus- und/oder Weiterbildungen sowie deren Vorteile werden nachfolgend anhand von Zeichnungen näher erläutert.The invention and its advantageous embodiments and / or developments and their advantages will be explained in more detail with reference to drawings.
