Description
Die Erfindung betrifft einen Batteriekasten, insbesondere für eine Batterie eines Kraftfahrzeugs, wie bspw. eines elektrisch oder teilweise elektrisch betriebenen Fahrzeugs.The invention relates to a battery box, in particular for a battery in a motor vehicle, such as an electrically or partially electrically operated vehicle.
In Elektrofahrzeugen oder Hybridfahrzeugen müssen verwendete Batterien bzw. die Zellen elektrochemischer Speicher geeignet verwahrt werden, so dass ein sicherer Betrieb gewährleistet ist.Batteries used in electric vehicles or hybrid vehicles or the cells of electrochemical storage must be stored appropriately so that safe operation is guaranteed.
Herkömmliche Batteriekästen bzw. Batteriegehäuse weisen eine Trennung zwischen eingebauten Funktionen und der lasttragenden Struktur auf. Dabei sind die Einzelfunktionen durch separate Bauteile bzw. Baugruppen und wieder gesonderte Verbindungen dargestellt. Der Aufbau besteht in der Regel aus einem die Zellen vollständig oder teilweise umschließenden Gehäuse und einer Kühlung bzw. Temperierung oder einfacher Belüftung. Die Anbindung an das Fahrzeug erfolgt üblicherweise über eine gesonderte und aufgrund der Anforderungen sehr massive Trägerstruktur. Bedingt durch die Vielfalt der eingesetzten Teile und die vornehmliche Verwendung metallischer Elemente weisen bekannte Lösungen ein hohes Eigengewicht auf.Conventional battery boxes or battery housings have a separation between built-in functions and the load-bearing structure. The individual functions are represented by separate components or assemblies and again separate connections. The structure usually consists of a housing that completely or partially encloses the cells and cooling or temperature control or simple ventilation. The connection to the vehicle is usually via a separate and, due to the requirements, very massive support structure. Due to the variety of parts used and the primary use of metallic elements, known solutions have a high intrinsic weight.

Die beiden Druckschriften beschreiben vollständig luftgekühlte Batteriesysteme, die aus vielen, jeweilige Einzelfunktionen abbildenden Elementen bestehen.The two publications describe completely air-cooled battery systems that consist of many elements that represent individual functions.
Aus der Druckschrift
Die Druckschrift zeigt einen integrativen Ansatz eines Batteriekastens aus Kunststoff, der die einzelnen Zellen in bestimmter Weise ausrichtet. Die Struktur wird als leicht und selbsttragend bezeichnet und umfasst durch doppelte Zwischenwände aktive Kühlkanäle. Eine Anbindung an ein Gesamtsystem und ein ausreichender Schutz im Schadensfall sowie eine elektromagnetische Abschirmung werden nicht berücksichtigt. Es liegt somit eine Einzelkomponente und kein System vor.The publication shows an integrative approach to a battery box made of plastic, which aligns the individual cells in a specific way. The structure is characterized as light and self-supporting and includes active cooling channels through double partitions. A connection to an overall system and adequate protection in the event of damage as well as electromagnetic shielding are not taken into account. It is therefore an individual component and not a system.

Die Druckschrift
Bislang ist keine integrative Verbundstruktur bekannt, die neben der notwendigen Ausrichtung der Zellen ein komplettes Mikroklima für eine optimale Batterietemperierung, thermische und elektrische Isolation sowie eine elektromagnetische Abschirmung des Systems gewährleistet und zugleich einen ausreichenden Schutz im Schadensfall bietet und darüber hinaus eine deutliche Gewichtsreduktion mit sich bringt.So far, no integrative composite structure is known that, in addition to the necessary alignment of the cells, ensures a complete microclimate for optimal battery temperature control, thermal and electrical insulation and electromagnetic shielding of the system and at the same time offers sufficient protection in the event of damage and also brings with it a significant weight reduction .
Aufgabe ist, einen Batteriekasten vorzustellen, mit dem die vorstehend genannten Ziele erreicht werden können.The task is to present a battery box with which the above goals can be achieved.
Vor diesem Hintergrund wird ein Batteriekasten nach Anspruch 1 vorgestellt.Against this background, a battery box according to claim 1 is presented.
Der vorgestellte Batteriekasten bzw. Batterieträger dient insbesondere für eine Batterie in einem Kraftfahrzeug, wie bspw. einem Elektro- oder Hybridfahrzeug. Dabei weist der Batteriekasten eine Oberschale, eine Unterschale und eine Schale aus einem metallischen Material, wie bspw. ein Metallblech, auf, die die Unterschale zumindest teilweise bzw. abschnittsweise umgibt.The presented battery box or battery carrier is used in particular for a battery in a motor vehicle, such as an electric or hybrid vehicle. In this case, the battery box has an upper shell, a lower shell and a shell made of a metallic material, such as a metal sheet, which surrounds the lower shell at least partially or in sections.
Die Oberschale und die Unterschale sind aus einem Kunststoff, wie bspw. einem faserverstärktem Kunststoff, gefertigt.The upper shell and the lower shell are made of a plastic, such as a fiber-reinforced plastic.
Die Schale aus einem metallischen Werkstoff kann formschlüssig und/oder stoffschlüssig mit der Unterschale verbunden sein.The shell made of a metallic material can be connected to the lower shell in a form-fitting and/or material-to-material manner.
In Ausgestaltung ist die Oberschale mit einem leitenden Zusatz und/oder mit elektrisch leitenden Fasern versehen. Alternativ oder ergänzend kann die Oberschale von einem Blech zumindest teilweise umschlossen sein.In one embodiment, the upper shell is provided with a conductive additive and/or with electrically conductive fibers. Alternatively or additionally, the upper shell can be at least partially enclosed by a metal sheet.
In einer weiteren Ausführung ist eine weitere Schale vorgesehen. In diesem Fall bietet es sich an, wenn die Oberschale und die Unterschale als nicht lösbare Struktur ausgebildet sind.A further shell is provided in a further embodiment. In this case it makes sense if the upper shell and the lower shell are designed as a non-detachable structure.
Der beschriebene Batteriekasten bzw. das Batteriegehäuse besteht üblicherweise aus mindestens zwei schalenförmigen Strukturelementen, der Oberschale und der Unterschale, die die Batterie vollständig umschließen und diese vor Witterungseinflüssen, Fremdspannungen sowie unvorhergesehenen Beschädigungen schützen und elektromagnetisch abschirmen. Im Schadensfall, bspw. bei einem Zusammenstoß, hält der Batteriekasten bzw. Träger das Batteriesystem zurück und schützt es vor äußeren mechanischen Belastungen. Weiterhin verhindert dieser anschließende schädliche Wechselwirkungen mit der Umwelt, wie Überspannungen, auslaufende Flüssigkeiten und Brand.The battery box or battery housing described usually consists of at least two shell-shaped structural elements, the upper shell and the lower shell, which completely enclose the battery and protect it from the weather, external voltages and unforeseen damage and shield it electromagnetically. In the event of damage, e.g. in the event of a collision, the battery box or carrier holds the battery system back and protects it from external mechanical loads. Furthermore, this prevents subsequent harmful interactions with the environment, such as surges, leaking liquids and fire.
Der vorgestellte Batteriekasten weist durch das strukturelle Trägersystem ein hohes Maß an Funktionsintegration auf. Die Formgebung des Kunststoffs wird typischerweise dem Batteriesystem angepasst, wodurch die Fixierung und Ausrichtung des Systems sowie einzelner Komponenten und Anbauelemente durch die Strukturschale ermöglicht wird. Trennelemente, wie bspw. ein Kammeraufbau, können mit dargestellt werden. Ebenso können Schnittstellen für die benötigte Peripherie, z.B. Leistungselektronik, Batterieüberwachung und die externen Anschlüsse, realisiert werden. Zudem bietet sich die Möglichkeit, die Kühlung bzw. die Kühlkanäle sowie deren Verlauf, Anbindungspunkte, Zu- und Ablauf, in den Strukturschalen, d.h. der Oberschale und der Unterschale, mit abzubilden.The battery box presented has a high degree of functional integration due to the structural support system. The shape of the plastic is typically adapted to the battery system, which allows the system and individual components and add-on elements to be fixed and aligned by the structural shell. Separating elements, such as a chamber structure, can also be represented. Interfaces for the required peripherals, e.g. power electronics, battery monitoring and external connections can also be implemented. In addition, there is the possibility of depicting the cooling or the cooling channels as well as their course, connection points, inlet and outlet, in the structural shells, i.e. the upper shell and the lower shell.
Aufgrund der Isolationswirkung der verwendeten Kunststoffmatrix entsteht eine abgeschlossene klimatische Einheit, die separat temperiert werden kann und somit einen optimalen Batteriebetrieb gewährleistet.Due to the insulating effect of the plastic matrix used, a closed climatic unit is created that can be temperature-controlled separately and thus ensures optimal battery operation.
Die einzelnen Bauteile bzw. Bestandteile des beschriebenen Batteriekastens erfüllen unterschiedliche Funktionen. So dient die Unterschale einer Funktionsintegration, der Abbildung von Zusatzfunktionen, der thermischen Isolation des Batteriesystems, der elektrischen Isolation, der Gewichtsreduktion durch Stoff- und Strukturleichtbau, der Kraftaufnahme und Kraftübertragung im Schadensfall und der Dichtheit bzw. Leckagevermeidung. Die Oberschale wirkt entsprechend.The individual components or components of the battery box described fulfill different functions. The lower shell is used for functional integration, the mapping of additional functions, the thermal insulation of the battery system, electrical insulation, weight reduction through material and structural lightweight construction, power absorption and power transmission in the event of damage and tightness or leakage prevention. The upper shell works accordingly.
Die Schale aus einem metallischen Material bzw. die Blechunterschale dient der elektromagnetischen Abschirmung, ggf. der Gewichtsreduktion durch Stoff- und Strukturleichtbau, der Kraftaufnahme und Kraftübertragung im Schadensfall und der Dichtheit bzw. Leckagevermeidung.The shell made of a metallic material or the lower sheet metal shell is used for electromagnetic shielding, possibly weight reduction through material and structural lightweight construction, force absorption and force transmission in the event of damage and tightness or leakage prevention.
Der elektrisch leitende Zusatz bzw. das Blech der Oberschale dient der elektromagnetischen Abschirmung und ggf. der Gewichtsreduktion durch Stoff- und Strukturleichtbau.The electrically conductive additive or the sheet metal of the upper shell is used for electromagnetic shielding and, if necessary, for weight reduction through lightweight material and structure.
In einer besonderen Ausführung besteht der Batteriekasten aus der Oberschale, der Unterschale und einer dritten Schale, die die beschriebene Funktionsintegration sowie die Seitenschalen inkludiert. In diesem Fall sind die Oberschale und die Unterschale typischerweise als nicht lösbare, stoffschlüssige Struktur zur besseren Kraftübertragung in Fahrtrichtung ausgeprägt. Die dritte Schale ist dann lösbar. Das Batteriesystem wird daher seitlich in die Struktur, d.h. den Batteriekasten, eingeführt.In a special version, the battery box consists of the upper shell, the lower shell and a third shell, which includes the functional integration described and the side shells. In this case, the upper shell and the lower shell are typically designed as a non-detachable, materially bonded structure for better power transmission in the direction of travel. The third shell can then be detached. The battery system is therefore introduced laterally into the structure, i.e. the battery box.
Der beschriebene Batteriekasten ermöglicht somit, zumindest in einigen der Ausführungen eine Integration verschiedener Funktionen, nämlich:
- - Anbindung an das Fahrzeug
- - elektromagnetische Abschirmung
- - Temperierung
- - Eigenstabilität
- - Connection to the vehicle
- - electromagnetic shielding
- - Tempering
- - Intrinsic stability
Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und der beiliegenden Zeichnung.Further advantages and refinements of the invention result from the description and the attached drawing.
Es versteht sich, dass die voranstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It goes without saying that the features mentioned above and those still to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.
Die Erfindung ist anhand von Ausführungsformen in der Zeichnung schematisch dargestellt und wird nachfolgend unter Bezugnahme auf die Zeichnung ausführlich beschrieben.

Die Unterschale 14 wird zusätzlich von einer Schale 16 aus einem metallischen Material, in diesem Fall einem dünnen metallischen Blech, umschlossen. Dieses Blech ist fixiert und form- oder stoffschlüssig befestigt, verklebt, hinterpresst und/oder hinterspritzt. Die Schale 16 bietet während des Betriebs eine elektromagnetische Abschirmung und im Schadensfall eine Unterstützung der Kunststoffstruktur und eine nachträgliche Abgrenzung von der Umwelt. Zur Gewichtsreduktion ist die metallische Schale 16 bzw. das Blech so dünn wie möglich ausgeprägt. Lediglich der sich ergebende Gesamtverbund nimmt alle geforderten Kräfte auf und verhindert unkontrollierte lokale Zerstörungen, wie bspw. Risse, des Kunststoffs sowie übergroße Deformationen des Blechs und eine eventuell daraus resultierende Leckage des Gesamtsystems. Das Blech bzw. Stahlblech kann im montierten Zustand ein Karosserieteil, z.B. den Fahrzeugboden, abbilden. The
