Abstract
Description
Die Erfindung betrifft einen elektrischen Energiespeicher für Kraftfahrzeuge gemäß Oberbegriff des Patentanspruchs 1.The The invention relates to an electrical energy storage for Motor vehicles according to the preamble of the claim 1.
Aus dem Stand der Technik ist es seit langem bekannt, bei einem Fahrzeugaufprall die kinetische Energie über sogenannte Knautschzonen aufnehmen und zu verteilen.Out The prior art has long been known in a vehicle crash absorb the kinetic energy via so-called crumple zones and to distribute.
Ferner ist es für elektrische Energiespeicher bekannt, insbesondere für Traktionsbatterien eines Hybrid- oder Elektrofahrzeuges massive Gehäuse vorzusehen, um im Falle eines Crashs eine Verformung des Energiespeichers oder dessen Speicherkomponenten sowie ein unkontrolliertes Eindringen in den Fahrgastraum zu verhindern, da ansonsten die Insassen aufgrund von Kurzschlüssen und unkontrollierten elektrochemischen Reaktion einer erhöhten Verletzungsgefahr ausgesetzt sind.Further It is known for electrical energy storage, in particular for traction batteries of a hybrid or electric vehicle To provide massive housing, in case of a crash Deformation of the energy storage or its storage components as well as to prevent an uncontrolled intrusion into the passenger compartment, otherwise the occupants due to short circuits and uncontrolled electrochemical reaction of increased risk of injury are exposed.
Da für solche zukünftigen Energiespeichersysteme das benötigte Bauraumvolumen zunimmt, wird aus Gewichtsgründen vermehrt auf separate Batteriegehäuse verzichtet und diese Energiespeicher in die Fahrzeugstruktur integriert, jedoch werden solche Strukturteile lokal sehr steif ausgelegt, um eine Verformung des Energiespeichers bzw. dessen Komponenten weitestgehend zu vermeiden, wodurch sich jedoch in nachteiliger Weise das Fahrzeuggewicht erhöht und dies deshalb zu hohen Herstellkosten führt.There for such future energy storage systems The required space increases, is due to weight reasons increasingly dispensed with separate battery housing and this Energy storage integrated into the vehicle structure, however such structural parts locally very stiff designed to deformation of the energy store or its components as far as possible to avoid which, however, disadvantageously increases the vehicle weight and this therefore leads to high production costs.
So
ist aus der
Der Nachteil dieser bekannten gehäusten Traktionsbatterie liegt einmal in deren hohen Herstellkosten, da hierfür bis zu 300 Einzelzellen erforderlich sind und zum anderen darin, dass diese bekannte gehäuste Traktionsbatterie nur außerhalb der Fahrgastzelle einsetzbar ist, da ansonsten im Falle eines Berstens des Gehäuses die Einzelzellen unkontrolliert in den Fahrgastraum gelangen könnten.Of the Disadvantage of this known housing traction battery is once in their high production costs, since this up to 300 single cells are required and, secondly, that these known housed traction battery just outside the passenger compartment is usable, otherwise in case of bursting of the housing, the individual cells uncontrolled in the passenger compartment could arrive.
Aufgabe der Erfindung ist es, ein Gehäuse für einen elektrischen Energiespeicher bereitzustellen, das bei einem Fahrzeugzusammenstoß eine Beschädigung des Energiespeichers verhindert, aber gleichzeitig die oben genannten Nachteile vermeidet, ohne das Gewicht der Fahrzeugkarosserie wesentlich zu erhöhen.task The invention is a housing for an electrical Energy storage to provide in a vehicle collision a Damage to the energy storage prevents, but at the same time avoid the above-mentioned disadvantages, without the weight of the vehicle body significantly increase.
Diese Aufgabe wird gelöst durch einen elektrischen Energiespeicher für Kraftfahrzeuge gemäß den Merkmalen des Patentanspruches 1.These Task is solved by an electrical energy storage for motor vehicles according to the features of claim 1.
Durch die erfindungsgemäße Ausbildung wenigstens einer Seitenwand mit wenigstens einem zwischen zwei aneinandergrenzenden Modulen liegenden Wandungsabschnitt, der bei einer vorbestimmten Krafteintragung zu einer definierten Verformung der Seitenwand führt, erfolgt ein gezielter Energieabbau im Falle eines Crashs, wobei gleichzeitig eine kontrollierte Relativbewegung der Module des Energiespeichers möglich ist. Dadurch sind auch die Kräfte, die beim Crash auf ein einzelnes Modul wirken wegen dessen kleineren Massenträgheit geringer im Vergleich zur Massenträgheit des gesamten Energiespeichers. Dies erlaubt eine Reduzierung der Steifigkeit der Seitenwände gegenüber einem massiven Batteriegehäuse aus dem Stand der Technik und führt daher auch zu einem geringeren Fahrzeuggewicht. Insbesondere lässt sich mit dieser erfindungsgemäßen Ausbildung der Seitenwände ein elektrischer Energiespeicher, vorzugsweise eine Traktionsbatterie, auch im Fahrgastraum unterbringen, vorzugsweise in den Fahrzeugtunnel eines Kraftfahrzeugs integrieren.By the inventive design at least one Sidewall with at least one between two adjoining ones Modules lying wall portion which at a predetermined Force entry leads to a defined deformation of the side wall, there is a targeted energy reduction in the event of a crash, wherein simultaneously a controlled relative movement of the modules of the energy storage is possible. As a result, the forces that are crash on a single module because of its smaller size Mass inertia lower compared to inertia the entire energy storage. This allows a reduction in rigidity the side walls opposite a massive battery case from the prior art and therefore leads to a lower vehicle weight. In particular, can be with this inventive design of the side walls an electrical energy store, preferably a traction battery, also in the passenger compartment, preferably in the vehicle tunnel to integrate a motor vehicle.
Bei einer Weiterbildung der Erfindung wird der Wandungsabschnitt mit geringerer Festigkeit, vorzugsweise materialreduziert gegenüber dem umliegenden Bereich der Seitenwand ausgebildet. Dies kann besonders einfach mit einer Entlastungskerbe realisiert werden.at a development of the invention, the wall section with lower strength, preferably reduced material formed around the surrounding area of the side wall. This can be special can be easily realized with a relief notch.
Idealerweise verläuft die wenigstens eine Seitenwand in Fahrtrichtung des Kraftfahrzeugs, wodurch insbesondere bei Seiten-Crashs ein Krafteintrag auf die Seitenwand erfolgt und damit ein Energieabbau durch die gezielte Verformung und kontrollierte Verlagerung der einzelnen Module erfolgt.Ideally the at least one side wall runs in the direction of travel of the motor vehicle, which in particular in side crashes a force entry takes place on the side wall and thus an energy reduction by the targeted deformation and controlled displacement of the individual Module is done.
Insbesondere ist es gemäß einer Weiterbildung der Erfindung von Vorteil, zur Bildung von Deformationsräumen zwischen den Modulen dieselben in einem vorbestimmten Abstand anzuordnen, so dass bei einem Frontal-Crash die Seitenwände durch Wölbung oder Faltung als Knautschzonen funktionieren und sich dabei die Abstände zwischen den Modulen entsprechend verringern, dadurch die Krafteinwirkung auf die einzelnen Module reduziert wird und gleichzeitig ein Energieabbau erfolgt.Especially it is according to a development of the invention beneficial to the formation of deformation spaces between to arrange the modules at a predetermined distance, so that in a frontal crash the side walls by curvature or folding as crumple zones work and thereby the Reduce spacing between modules accordingly as a result the force effect on the individual modules is reduced and at the same time an energy reduction takes place.
Eine vorteilhafte Weiterbildung der Erfindung ergibt sich, wenn die wenigstens eine Seitenwand als Strukturteil einer Fahrzeugkarosserie des Kraftfahrzeugs ausgebildet ist, vorzugsweise wenn diese Seitenwände als Teil eines Fahrzeugtunnels den Energiespeicher wenigstens teilweise einschließen. Damit wird insbesondere dann, wenn der Energiespeicher eine Traktionsbatterie für ein Hybrid- oder Elektrofahrzeug darstellt unter dem Aspekt der Gewichtsoptimierung bzw. der Leichtbauweise des Kraftfahrzeugs eine gute Lösung erzielt und dabei ein größtmöglicher Schutz der Insassen sichergestellt.An advantageous development of the invention results when the at least one side wall is formed as a structural part of a vehicle body of the motor vehicle, preferably when these side walls as part of a vehicle tunnel the energy include at least partially. Thus, in particular when the energy storage is a traction battery for a hybrid or electric vehicle under the aspect of weight optimization or the lightweight construction of the motor vehicle achieved a good solution, while ensuring the greatest possible protection of the occupants.
