Abstract
Description
Die Erfindung betrifft ein Fahrzeug mit einer Batterie und einer Fahrzeug-Tragstruktur, nach der im Anspruch 1 näher definierten Art.The invention relates to a vehicle with a battery and a vehicle support structure, according to the defined in
Aus dem allgemeinen Stand der Technik sind Fahrzeuge bekannt, welche zumindest teilweise elektrisch angetrieben werden. Diese Fahrzeuge benötigen Batterien, welche auch als Traktionsbatterien bezeichnet werden, die elektrische Leistung für den Vortrieb des Fahrzeugs speichern. Diese Batterien müssen im Fahrzeug sicher, stabil und möglichst platzsparend untergebracht werden, um beispielsweise den Laderaum in dem Fahrzeug nicht oder nur unwesentlich zu schmälern.From the general state of the art, vehicles are known which are at least partially electrically driven. These vehicles require batteries, also referred to as traction batteries, which store electrical power for propulsion of the vehicle. These batteries must be safely, stably and space-saving housed in the vehicle, for example, not to diminish the cargo space in the vehicle or only insignificantly.
Aus der
Bei den allgemein üblichen Aufbauten ist es daher vorgesehen, dass Entlüftungsöffnungen der Batterie, welche typischerweise im Bereich eines die Gesamtbatterie umgebenden Batteriegehäuses angeordnet sind, über entsprechende Leitungselemente mit der Umgebung des Fahrzeugs verbunden sind. Diese Leitungselemente müssen dicht mit der Entlüftungsöffnung verbunden werden und so in dem Fahrzeug verlegt werden, dass ein Eindringen der im Falle eines Überdrucks abströmenden Gase in den Innenraum des Fahrzeugs sicher und zuverlässig vermieden wird. Der Aufwand hinsichtlich der Leitungselemente, der Leitungsführung sowie der Konstruktion und Abdichtung von Schnittstellen ist damit vergleichsweise groß.In the case of the generally customary constructions, it is therefore provided that vents of the battery, which are typically arranged in the region of a battery housing surrounding the overall battery, are connected via corresponding line elements to the surroundings of the vehicle. These line elements must be tightly connected to the vent opening and laid in the vehicle so that penetration of the outflowing in the event of overpressure gases into the interior of the vehicle safely and reliably avoided. The effort in terms of line elements, the wiring as well as the construction and sealing of interfaces is thus comparatively large.
Aus dem weiteren allgemeinen Stand der Technik ist es außerdem bekannt, Batterien im Bereich einer Tragstruktur eines Fahrzeugs anzuordnen.From the further general state of the art, it is also known to arrange batteries in the region of a supporting structure of a vehicle.
In der
Aus der
Die beiden beschriebenen Schriften schildern also jeweils die Integration von Brennstoffzellen oder von Batterien in bestehende Hohlräume der Tragstruktur eines Fahrzeugs.The two described writings thus each describe the integration of fuel cells or of batteries into existing cavities of the supporting structure of a vehicle.
Die Aufgabe der hier vorliegenden Erfindung besteht nun darin, ein Fahrzeug mit einer Batterie anzugeben, bei welchem der benötigte Bauraum minimiert werden kann.The object of the present invention is now to provide a vehicle with a battery, in which the required space can be minimized.
Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil von Patentanspruch 1 genannten Merkmale gelöst. Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Lösung ergeben sich aus den hiervon abhängigen Unteransprüchen.According to the invention, this object is achieved by the features mentioned in the characterizing part of
Bei dem erfindungsgemäßen Fahrzeug ist es also vorgesehen, dass die wenigstens eine Entlüftungsöffnung der Batterie mit dem Innenraum wenigstens eines der als Hohlprofile ausgebildeten Trägers, und über diesen direkt oder über weitere als Hohlprofile ausgebildete Träger mit der Umgebung des Fahrzeugs in Verbindung stehen. Die typischerweise ohnehin als Hohlprofile ausgebildeten Träger, welche oft als Rohre mit rundem oder rechteckigem Querschnitt ausgebildet werden, werden erfindungsgemäß als Leitungselemente zum Abführen der im Schadensfall aus der Entlüftungsöffnung der Batterie austretenden Gase genutzt. Typischerweise weisen die Hohlprofile der Träger einen entsprechend großen Querschnitt auf, sodass die vergleichsweise großen Gasmengen, welche sich im Schadensfall im Bereich der Batterie bilden, durch die Träger problemlos abgeführt werden können. Die als Hohlprofile ausgebildeten Träger stehen an ihren Stirnseiten typischerweise mit dem Außenbereich der Fahrzeugkarosserie in Verbindung und weisen keine Verbindung zum Innenraum des Fahrzeugs auf. Sie sind daher ideal geeignet, die Gase an die Umgebung abzuführen, ohne die Insassen eines Fahrzeugs zu gefährden. Auf zusätzliche Leitungselemente, wie sie beim Stand der Technik notwendig sind, kann hier verzichtet werden. Es muss lediglich eine Öffnung an geeigneter Stelle im Bereich des Trägers oder gegebenenfalls am Übergang von einem der Träger in einen anderen der Träger vorgesehen werden.In the vehicle according to the invention, it is thus provided that the at least one vent opening of the battery are in communication with the interior of at least one of the carriers designed as hollow profiles, and via these directly or via further carrier designed as hollow profiles with the surroundings of the vehicle. The typically anyway designed as hollow beams carrier, which are often formed as tubes with a round or rectangular cross-section, are used according to the invention as line elements for discharging the leaking in the event of damage from the vent of the battery gases. Typically, the hollow profiles of the carrier have a correspondingly large cross-section, so that the comparatively large amounts of gas which form in the event of damage in the region of the battery, can be removed easily by the carrier. The carrier designed as hollow profiles are typically connected at their front sides to the outer region of the vehicle body and have no connection to the interior of the vehicle. They are therefore ideally suited to dissipate the gases to the environment, without endangering the occupants of a vehicle. On additional line elements, as they are necessary in the prior art, can be omitted here. It is only necessary to provide an opening at a suitable point in the region of the carrier or, if appropriate, at the transition from one of the carriers into another of the carriers.
Der Aufbau ist daher hinsichtlich des Bauraums, der benötigten Bauteile und insbesondere hinsichtlich des Montage- und Abdichtungsaufwands gegenüber den Aufbauten aus dem Stand der Technik prädestiniert.The structure is therefore predestined with respect to the installation space, the required components and in particular with regard to the assembly and sealing effort compared to the structures of the prior art.
In einer günstigen Ausgestaltung des erfindungsgemäßen Fahrzeugs ist es ferner vorgesehen, dass die Batterie im Bereich der Tragstruktur angeordnet ist. Eine solche Anordnung der Batterie im Bereich der Tragstruktur ist für das erfindungsgemäß aufgebaute Fahrzeug ideal, da hierdurch eventuelle Leitungselemente zwischen der Entlüftungsöffnung und dem Eintritt in die Hohlprofile der Tragstruktur minimiert oder weggelassen werden können.In a favorable embodiment of the vehicle according to the invention, it is further provided that the battery is arranged in the region of the support structure. Such an arrangement of the battery in the region of the support structure is ideal for the vehicle constructed according to the invention, as this can minimize or omit any conduit elements between the vent opening and the entry into the hollow sections of the support structure.
In einer weiteren sehr günstigen Ausgestaltung des erfindungsgemäßen Fahrzeugs ist es dementsprechend vorgesehen, dass die Batterie ein Batteriegehäuse mit wenigstens einer Entlüftungsöffnung aufweist, wobei die wenigstens eine Entlüftungsöffnung direkt mit wenigstens einer Öffnung in wenigstens einem der Träger zusammenwirkt.In a further very favorable embodiment of the vehicle according to the invention, it is accordingly provided that the battery has a battery housing with at least one ventilation opening, wherein the at least one ventilation opening interacts directly with at least one opening in at least one of the carriers.
In diesem besonders bevorzugten Aufbau des erfindungsgemäßen Fahrzeugs kann also auf sämtliche Leitungselemente verzichtet werden, indem die Entlüftungsöffnung eines Batteriegehäuses der Batterie unmittelbar mit dem Träger zusammenwirkt. Hier kann eine feste Verbindung, beispielsweise eine stoffschlüssige oder formschlüssige Verbindung, vorliegen oder es kann über ein Dichtelement eine abdichtende Verbindung geschaffen werden. Bei dem Aufbau ist dann lediglich ein einziges Dichtelement zwischen dem Batteriegehäuse und dem Träger notwendig oder kann bei stoffschlüssiger Verbindung ganz wegfallen.In this particularly preferred structure of the vehicle according to the invention can therefore be dispensed with all line elements by the vent opening of a battery case of the battery interacts directly with the carrier. Here, a solid connection, for example, a cohesive or positive connection, be present or it can be created via a sealing element a sealing connection. In the structure then only a single sealing element between the battery case and the carrier is necessary or can be completely eliminated in cohesive connection.
In einer besonders günstigen und vorteilhaften Weiterbildung des erfindungsgemäßen Fahrzeugs ist es außerdem vorgesehen, dass die Batterie ein Batteriegehäuse aufweist, wobei das Batteriegehäuse oder ein Teil des Batteriegehäuses, insbesondere eine Bodenwanne des Batteriegehäuses, als Bauteil der Tragstruktur ausgebildet ist.In a particularly favorable and advantageous development of the vehicle according to the invention, it is also provided that the battery has a battery case, wherein the battery case or a part of the battery case, in particular a bottom trough of the battery case is formed as a component of the support structure.
In dieser besonders bevorzugten Weiterbildung kann das Batteriegehäuse oder ein Teil des Batteriegehäuses also sowohl eine Funktion als Batteriegehäuse übernehmen, als auch eine tragende Funktion als Bauteil in der Tragstruktur des Fahrzeugs. Durch diese Doppelfunktionalität des Batteriegehäuses als Batteriegehäuse einerseits und als Bauteil der Tragstruktur des Fahrzeugs andererseits lässt sich weiterer Bauraum einsparen, da auf Teile der herkömmlichen Tragstruktur, welche durch das Batteriegehäuse oder einen Teil des Batteriegehäuses ersetzt werden, verzichtet werden kann.In this particularly preferred development, the battery housing or a part of the battery housing can therefore assume both a function as a battery housing, as well as a supporting function as a component in the support structure of the vehicle. By this dual functionality of the battery case as a battery case on the one hand and as a component of the support structure of the vehicle on the other hand, further space can be saved because of parts of the conventional support structure, which are replaced by the battery case or part of the battery case can be omitted.
Die Verwendung des Batteriegehäuses oder eines Teil des Batteriegehäuses als Bauteil der Tragstruktur ermöglicht eine stabile und steife Tragstruktur einerseits und erlaubt es andererseits, den elektrochemischen Aufbau der Batterie, welcher typischerweise in Form von einem oder mehreren Stapeln von prismatischen Batterieeinzelzellen ausgebildet ist, in herkömmlicher Art und Weise – vergleichsweise weich – auszuführen. Damit lässt sich Aufwand bei der Herstellung der Batterie und Baugewicht bei der Batterie einsparen, während gleichzeitig zumindest ein Teil des ohnehin benötigten Batteriegehäuses als hochstabiles Bauteil der Tragstruktur ausgebildet werden kann.The use of the battery housing or a part of the battery housing as a component of the support structure allows a stable and rigid support structure on the one hand and on the other hand allows the electrochemical structure of the battery, which is typically in the form of one or more stacks of prismatic battery cells, in a conventional manner and Way - comparatively soft - execute. This can be effort in the production of the battery and construction weight in the battery can be saved, while at the same time at least a portion of the already required battery housing can be formed as a highly stable component of the support structure.
In einer sehr vorteilhaften Weiterbildung hiervon ist es ferner vorgesehen, dass das Batteriegehäuse wenigstens ein Versteifungselement, insbesondere in Form von Kühlvorrichtungen für die Batterie, aufweist.In a very advantageous development thereof, it is further provided that the battery housing has at least one stiffening element, in particular in the form of cooling devices for the battery.
Ein solches Versteifungselement in dem Batteriegehäuse kann dazu dienen, das Batteriegehäuse als Bauteil der Tragstruktur ausreichend stabil und steif auszubilden, ohne dabei das gesamte Batteriegehäuse unnötig schwer ausführen zu müssen.Such a stiffening element in the battery case can serve to make the battery case sufficiently stable and rigid as a component of the supporting structure, without having to unnecessarily perform the entire battery case unnecessarily.
Der typische Aufbau von Batterien, wie sie beispielsweise als Traktionsbatterien in zumindest teilweise elektrisch angetriebenen Fahrzeugen eingesetzt werden, sieht es vor, dass Batterieeinzelzellen verwendet werden, welche einer aktiven Kühlung bedürfen. Diese Batterieeinzelzellen, beispielsweise in Lithium-Ionen-Technologie, werden häufig als prismatische Batterieeinzelzellen zu einem oder mehreren Zellenstapeln aufgestapelt und zu der Batterie vereint. Um eine sichere und gleichmäßige Kühlung der Batterieeinzelzellen sicherstellen zu können, ist es häufig vorgesehen, dass wenigstens eine Kühlvorrichtung, welche oft als Platte oder in Form von Rohren ausgebildet ist und auf einer oder mehreren der Seiten des Zellenstapels angeordnet ist, zur Temperierung und Kühlung der Batterieeinzelzellen vorhanden ist. Diese Kühlvorrichtung, welche insbesondere als metallische Platte, welche aktiv von einem Kühlmedium, beispielsweise dem Kühlmittel einer Klimaanlage, durchströmt wird, ausgebildet ist, ist typischerweise sehr steif und kann neben der Funktionalität der Kühlung ideal auch die Funktionalität eines Versteifungselements in dem Batteriegehäuse übernehmen. Der Aufbau kann so ein sehr steifes Batteriegehäuse bereitstellen, welches sich ideal als Bauteil der Tragstruktur des Fahrzeugs eignet, und welches durch die Ausbildung der Versteifungselemente als Kühlvorrichtung zusätzlich Bauraum und Gewicht einer separaten Kühlvorrichtung oder separater Versteifungselemente einsparen kann. The typical structure of batteries, such as are used as traction batteries in at least partially electrically powered vehicles, it provides that single battery cells are used, which require active cooling. These single battery cells, for example in lithium-ion technology, are often stacked as prismatic single battery cells to one or more cell stacks and combined into the battery. In order to be able to ensure reliable and uniform cooling of the individual battery cells, it is often provided that at least one cooling device, which is often formed as a plate or in the form of tubes and is arranged on one or more of the sides of the cell stack, for tempering and cooling the Single battery cells is present. This cooling device, which is designed in particular as a metallic plate, which is actively flowed through by a cooling medium, for example the coolant of an air conditioning system, is typically very stiff and, in addition to the functionality of the cooling, can ideally also assume the functionality of a stiffening element in the battery housing. The structure can thus provide a very rigid battery housing, which is ideally suitable as a component of the support structure of the vehicle, and which can save additional space and weight of a separate cooling device or separate stiffening elements by forming the stiffening elements as a cooling device.
In einer sehr vorteilhaften Weiterbildung des erfindungsgemäßen Fahrzeugs ist es ferner vorgesehen, dass die Batterie als Traktionsbatterie zur Speicherung von elektrischer Antriebsleistung in dem zumindest teilweise elektrisch angetriebenen Fahrzeug vorgesehen ist. Die Batterie eignet sich insbesondere als Traktionsbatterie beispielsweise für ein Elektrofahrzeug oder insbesondere für ein Hybridfahrzeug, da sie weitgehend bauraumneutral in den bisherigen Aufbau der Tragstruktur des Fahrzeugs integriert werden kann und daher sehr platzsparend auch in bestehende Antriebskonzepte mit Verbrennungsmotor integrierbar ist. Eine Hybridisierung des Fahrzeugs wird damit einfach und effizient möglich.In a very advantageous development of the vehicle according to the invention, it is further provided that the battery is provided as a traction battery for storing electrical drive power in the at least partially electrically driven vehicle. The battery is particularly suitable as a traction battery, for example, for an electric vehicle or in particular for a hybrid vehicle, since it can be largely space-neutral integrated into the previous structure of the support structure of the vehicle and therefore very space-saving in existing drive concepts with internal combustion engine can be integrated. A hybridization of the vehicle is thus easily and efficiently possible.
