Description

Batteriegehäuse für ein Fahrzeug  Battery housing for a vehicle
Technisches Gebiet (Technical Field) Technical Field
Die Erfindung betrifft ein Batteriegehäuse für ein Fahrzeug.  The invention relates to a battery housing for a vehicle.
Technischer Hintergrund (Background Art) Technical Background (Background Art)
Die zunehmende bzw. anhaltende Elektrifizierung von Fahrzeugen, insbesondere von Automobilen, und der gleichzeitige Kundenwunsch nach hohen Reichweiten solcher Fahrzeuge, erfordern die Entwicklung von leistungsfähigen Batteriekonzepten. Insbesondere Batteriegehäuse, welche die Batterien aufnehmen bzw. in welchen die Batterien integriert sind, haben in der Regel eine wesentliche Erstreckung über den Fahrzeugboden, welcher sich insbesondere im Wesentlichen unterhalb der Fahrgastzelle des Fahrzeugs befindet. Damit ergeben sich komplexe Anforderungen hinsichtlich der Faktoren Bauraum, Crashperformance, Gewicht, Dichtigkeit etc. Mehrere Batteriemodule werden entsprechend der benötigten Kapazität zu einer Fahrzeugbatterie zusammengefasst und mit Batteriemanagementsystem und Temperierungssystem (Kühlen/Heizen) in einem Batteriegehäuse montiert.  The increasing or prolonged electrification of vehicles, in particular of automobiles, and the simultaneous customer request for long ranges of such vehicles, require the development of powerful battery concepts. In particular, battery housing, which receive the batteries or in which the batteries are integrated, usually have a substantial extent over the vehicle floor, which is located in particular substantially below the passenger compartment of the vehicle. This results in complex requirements in terms of space factors, crash performance, weight, tightness, etc. Several battery modules are combined according to the required capacity to a vehicle battery and mounted with battery management system and temperature control system (cooling / heating) in a battery housing.
Insbesondere bestehen die an die Befestigung der einzelnen Batteriemodule im Innenraum des Batteriegehäuses vielseitige Anforderungen. Neben strukturellen Eigenschaften wie Crashsicherheit, Steifigkeit, ausreichender Deformationswiderstand bei hohen Beschleunigungen und Lebensdauer ist die Wirtschaftlichkeit der Lösung eine wichtige Eigenschaft. In den meisten Fällen wird die Befestigung der Batteriemodule mit aufwendigen Gussbauteilen (Befestigungselemente) realisiert. Die Fertigung dieser (Guss-)Bauteile ist sehr kostenaufwendig. Weiterhin verursachen diese (Guss-)Bauteile komplexe Montageprozesse mit formschlüssigen und adhäsiven Fügeprozessen. In particular, there are various requirements for the attachment of the individual battery modules in the interior of the battery case. In addition to structural properties such as crash safety, rigidity, sufficient deformation resistance at high accelerations and service life, the cost-effectiveness of the solution is an important feature. In most cases, the attachment of the battery modules is realized with elaborate cast components (fasteners). The production of these (cast) components is very expensive. Furthermore, these (cast) components cause complex assembly processes with positive and adhesive joining processes.
Zusammenfassung der Erfindung (Summary of Invention) Summary of Invention
Der Erfindung liegt die Aufgabe zu Grunde, ein im Vergleich zum Stand der Technik wirtschaftlicheres und einfach herstellbares Batteriegehäuse für ein Fahrzeug bereitzustellen.  The invention is based on the object to provide a more economical and easy to manufacture battery housing for a vehicle compared to the prior art.
Gelöst wird diese Aufgabe durch einen Batteriegehäuse für ein Fahrzeug mit den Merkmalen des Patentanspruchs l. Weitere vorteilhafte Ausführungsformen der Erfindung sind in den nachgelagerten Ansprüchen aufgeführt. This object is achieved by a battery housing for a vehicle with the features of claim l. Further advantageous embodiments of the invention are listed in the following claims.
Erfindungsgemäß ist ein Batteriegehäuse für ein Fahrzeug vorgesehen, welches - einen Kasten, welcher aus einem insbesondere seitlich umlaufenden Außenrahmen und einem Boden gebildet ist, welcher einen Innenraum aufweist, According to the invention, a battery housing is provided for a vehicle, which a box, which is formed from an in particular laterally encircling outer frame and a floor which has an interior,
- mindestens einen Querträger und/oder mindestens einen Längsträger, welcher im Innenraum des Kastens angeordnet ist und den Innenraum des Kastens in mehrere Modulfächer zur Aufnahme von Batteriemodulen unterteilt,  at least one cross member and / or at least one longitudinal member, which is arranged in the interior of the box and divides the interior of the box into a plurality of module compartments for receiving battery modules,
- Befestigungselemente zum Befestigen der Batteriemodule innerhalb der Modulfächer, - fasteners for securing the battery modules within the module compartments,
- einen Deckel zum zumindest bereichsweisen Abdecken des Innenraums des Kastens, wobei innerhalb der Modulfächer Befestigungselemente aus Blechmaterial angeordnet sind, umfasst. - A cover for at least partially covering the interior of the box, wherein within the module roof fasteners are arranged from sheet metal material comprises.
Die Erfinder haben festgestellt, dass durch das Vorsehen von Befestigungselementen aus Blechmaterial zur Befestigung der Batteriemodule eine im Vergleich zum Stand der Technik Batteriegehäuse wirtschaftlicher und einfacher hergestellt werden kann, insbesondere wenn das Blechmaterial aus Stahl, vorzugsweise beschichtetem Stahl bereitgestellt wird. Auch die Verwendung eines Blechmaterials aus Leichtmetall, wie zum Beispiel Aluminium bzw. Magnesium, oder Edelstahl ist denkbar. Blechmaterialien sind im Wesentlichen individuell formbar, können insbesondere an die Bauraumverhältnisse entsprechend anpassbar sein und können im Vergleich zu Gussbauteilen massereduziert ausgeführt sein. Der Kasten, welcher aus einem insbesondere seitlich umlaufenden Außenrahmen und einem Boden gebildet ist, kann einteilig oder mehrteilig ausgeführt sein. Der Außenrahmen und der Boden können einteilig aus einem Stahl zu einem Kasten insbesondere wannenförmig tiefgezogen sein. Der Kasten kann alternativ mehrteilig, aus unterschiedlichen Bauteilen zusammengebaut sein, beispielsweise durch mehrere den Außenrahmen bildenden, miteinander verbundenen Profilen und einem an die Profile (Außenrahmen) angebundenen Boden, welcher insbesondere aus einer Platte besteht. Als bevorzugtes Material kommt Stahl, insbesondere beschichteter Stahl zum Einsatz. Im Innenraum des Kastens ist mindestens ein Querträger und/oder mindestens ein Längsträger angeordnet, welcher den Innenraum des Kastens in mehrere Modulfächer zur Aufnahme von Batteriemodulen unterteilt. Der Quer- und/oder der Längsträger ist bevorzugt ein profilartiges Bauteil, insbesondere aus Stahl, vorzugsweise aus beschichtetem Stahl, mit einem besonders bevorzugt u- oder hutförmigem Querschnitt. Zum zumindest teilweise, vorzugsweise vollständigen Abdecken respektive Schließen des Innenraums des Kastens ist ein Deckel vorgesehen, welcher insbesondere mit dem Außenrahmen verbunden ist. Da der Deckel im Wesentlichen nur die Funktion des Abdeckens erfüllen soll, kann er aus Metall oder beispielsweise zur weiteren Gewichtsreduktion aus Kunststoff bestehen. Auch die Verwendung eines Werkstoffverbundes ist denkbar. Innerhalb der Modulfächer sind erfindungsgemäß Befestigungselemente aus Blechmaterial zum Befestigen der Batteriemodule angeordnet. The inventors have found that by providing sheet metal fasteners for securing the battery modules, a battery case can be made more economically and easily compared to the prior art, especially when the sheet material is made of steel, preferably coated steel. The use of a sheet metal material made of light metal, such as aluminum or magnesium, or stainless steel is conceivable. Sheet metal materials are substantially individually moldable, in particular can be adapted accordingly to the space requirements and can be designed reduced mass compared to cast components. The box, which is formed from a particular laterally encircling outer frame and a bottom, can be made in one piece or in several parts. The outer frame and the floor may be integrally deep-drawn in one piece from a steel to a box in particular trough-shaped. The box may alternatively be multi-part, assembled from different components, for example, by a plurality of the outer frame forming, interconnected profiles and a to the profiles (outer frame) tailed floor, which consists in particular of a plate. The preferred material is steel, in particular coated steel used. In the interior of the box at least one cross member and / or at least one longitudinal member is arranged, which divides the interior of the box into a plurality of module compartments for receiving battery modules. The transverse and / or the longitudinal carrier is preferably a profile-like component, in particular of steel, preferably of coated steel, with a particularly preferred u- or hat-shaped cross-section. For at least partially, preferably completely covering or closing the interior of the box, a lid is provided, which is in particular connected to the outer frame. Since the lid is to fulfill essentially only the function of covering, it can be made of metal or, for example, for further weight reduction of plastic consist. The use of a composite material is conceivable. Within the module compartments fasteners made of sheet metal material for fixing the battery modules are arranged according to the invention.
Jegliche Verbindung zwischen Deckel und Außenrahmen und Boden und Außenrahmen muss dicht ausgeführt sein, um ein Eindringen von Fremdstoffen, insbesondere von Spritzwasser während des Betriebs im eingebauten Zustand des Batteriegehäuses in den Innenraum respektive Batterieraum zu vermeiden. Any connection between the lid and outer frame and bottom and outer frame must be made tight to prevent ingress of foreign matter, especially splash water during operation in the installed state of the battery case in the interior or battery compartment.
Unterhalb des Bodens kann auch ein weiterer Boden, ein sogenannter Unterfahrschutz angeordnet sein, welche gemeinsam einen zusätzlichen Raum, zum Beispiel als Deformationsraum und/oder Bauraum für Kühleinrichtungen, ausbilden, in welchem insbesondere Kühlelemente zum Kühlen (Temperierungssystem) des Innenraums respektive des Kühlraums und andere Elemente (Batteriemanagementsystem) angeordnet sein können. Below the floor, another floor, a so-called underrun protection may be arranged, which together form an additional space, for example as a deformation space and / or space for cooling devices, in which in particular cooling elements for cooling (temperature control) of the interior respectively the refrigerator and others Elements (battery management system) can be arranged.
Gemäß einer ersten Ausgestaltung sind die Befestigungselemente in den Ecken der Modulfächer insbesondere in der zur Modulbefestigung benötigten Höhe angeordnet. Durch die Anordnung der Befestigungselemente in den Ecken der Modulfächer lässt sich nicht nur in vorteilhafter Weise jedes Batteriemodul besonders stabil, insbesondere betriebs- und verrutschsicher befestigen bzw. aufnehmen, sondern diese Anordnung kann auch positiv Einfluss im Falle eines Crashs durch eine Erhöhung des Deformationswiderstandes der Modulfächer in den Ecken nehmen. According to a first embodiment, the fastening elements are arranged in the corners of the module compartments, in particular in the height required for mounting the module. The arrangement of the fasteners in the corners of the module compartments not only advantageously each battery module can be particularly stable, especially secure against operation and slip record or record, but this arrangement can also positively influence in the event of a crash by increasing the deformation resistance of the module subjects take in the corners.
Gemäß einer weiteren Ausgestaltung ist das Befestigungselement ein separates Kantteil oder Tiefziehteil, welches insbesondere als halber Quader, beispielsweise als halber Würfel mit drei räumlich verlaufenden Seitenflächen ausgebildet ist, wobei die Seitenflächen im Wesentlichen orthogonal zueinander verlaufen. Im Falle der Anordnung der Befestigungselemente in den Ecken der Modulfächer dienen zwei der drei Seitenflächen zur Anbindung an den Querträger und/oder den Längsträger und/oder der inneren Wandung des insbesondere seitlich umlaufenden Außenrahmens. Vorzugsweise ist das Befestigungselement stoffschlüssig mit dem Querträger und/oder dem Längsträger und/oder der inneren Wandung des insbesondere seitlich umlaufenden Außenrahmens verbunden, insbesondere verschweißt. Die Positionierung des Befestigungselementes in Höhenausrichtung des Modulfaches ist individuell an die jeweiligen Bauraumverhältnisse anpassbar. Gemäß einer weiteren Ausgestaltung sind mindestens ein, insbesondere mindestens zwei Querträger und mindestens ein, insbesondere zwei Längsträger angeordnet, wobei die Verbindung zwischen dem Querträger und Längsträger und insbesondere der inneren Wandung des insbesondere seitlich umlaufenden Außenrahmens ausschließlich durch die Befestigungselemente erfolgt. Bei der Herstellung respektive Zusammenbau des Batteriegehäuses kann eine vorherige Verbindung zwischen Querträger und Längsträger und insbesondere der inneren Wandung des insbesondere seitlich umlaufenden Außenrahmens entfallen, wobei diese Maßnahme eine Reduzierung des Montageaufwandes bewirken und dadurch die Wirtschaftlichkeit erhöhen kann. According to a further embodiment, the fastening element is a separate edge part or deep-drawn part, which is designed in particular as a half cuboid, for example as a half cube with three spatially extending side surfaces, wherein the side surfaces are substantially orthogonal to each other. In the case of the arrangement of the fastening elements in the corners of the module roofs serve two of the three side surfaces for connection to the cross member and / or the longitudinal member and / or the inner wall of the particular laterally encircling outer frame. Preferably, the fastening element is integrally connected to the cross member and / or the longitudinal member and / or the inner wall of the particular laterally encircling outer frame, in particular welded. The positioning of the fastener in height orientation of the module compartment is individually adapted to the respective space conditions. According to a further embodiment, at least one, in particular at least two cross members and at least one, in particular two longitudinal members are arranged, wherein the connection between the cross member and side member and in particular the inner wall of the particular laterally encircling outer frame is done exclusively by the fasteners. In the preparation respectively assembly of the battery case, a prior connection between the cross member and the longitudinal member and in particular the inner wall of the particular laterally encircling outer frame omitted, this measure can cause a reduction of assembly costs and thereby increase the efficiency.
Gemäß einer weiteren Ausgestaltung sind die Batteriemodule mechanisch, insbesondere lösbar mit den Befestigungselementen verbindbar bzw. verbunden. Dies ermöglicht einen schnellen Zugriff insbesondere Austausch und Erneuerung der Batteriemodule im Falles einer Fehlfunktion bzw. Defektes. Besonders bevorzugt weist das Befestigungselement in zumindest einer der Seitenflächen ein Loch auf. Durch das Loch sind insbesondere Mittel zur Befestigung durchschiebbar bzw. einsteckbar, beispielsweise in Form einer Schraube. Weiter bevorzugt ist das Batteriemodul auf die Befestigungselemente aufsetzbar und gelangt zumindest mit der Seitenfläche des Befestigungselementes in Kontakt, welche das Loch aufweist und parallel zur Ebene des Bodens und/oder Deckels verläuft, wobei das Batteriemodul insbesondere an seinen Ecken Löcher aufweist, die im Wesentlichen korrespondierend zu den Löchern der Befestigungselemente ausgeführt sind, durch welche jeweils eine Schraube durchschiebbar ist, welche mit einer Mutter, insbesondere einer Käfigmutter das Batteriemodul kraftschlüssig und lösbar mit dem Befestigungselement verbinden kann. Durch das Vorsehen vorzugsweise eines Langloches können Fertigungstoleranzen ausgeglichen werden.
