Description
Die vorliegende Erfindung betrifft eine Batterie mit einem metallischen Gehäuse, enthaltend eine Vielzahl von Lithium-Ionen-Batteriezellen, wobei die Außenfläche ihres metallischen Gehäuses, bis auf funktionsbedingt nicht zu beschichtende elektrische Anschlüsse, mit einer elektrisch isolierenden, mechanisch festen und chemisch beständigen Oberfläche versehen ist sowie ein Verfahren zur Herstellung einer Beschichtung von metallischen Batteriegehäusen und ein Kraftfahrzeug mit einer Batterie dieser Art. The present invention relates to a battery having a metallic housing, containing a plurality of lithium-ion battery cells, wherein the outer surface of its metallic housing, except for functional reasons not to be coated electrical connections, is provided with an electrically insulating, mechanically strong and chemically resistant surface and a method for producing a coating of metal battery cases and a motor vehicle with a battery of this type.
Stand der TechnikState of the art
Lithium-Ionen-Batteriezellen, zusammengefasst in einem Batteriepack, für ein Batteriesystem oder ein aus mehreren Batteriepacks assembliertes Batteriesystem besitzen in der Regel metallische Gehäuseoberflächen und letzteres metallische Gehäuseteile, die zur Aufnahme der Lithium-Ionen-Batteriezellen oder der Batteriezellenpacks vorbereitet sind. Die Lithium-Ionen-Batteriezellen besitzen in der Regel eine zylindrische oder eine prismatische Ausbildung. Im Falle eines Kurzschlusses kann eine Kettenreaktion das Batteriesystem erheblich schädigen, da bei einer aufgeladenen Traktionsbatterie ein bis zu 1000 A starker Strom kurzzeitig fließen kann. Kurzschlüsse können dabei durch Vorgänge in dem Batteriesystem oder durch äußere Einflüsse, beispielsweise durch einen Crash, herbeigeführt werden. Zur Vermeidung von Folgeschäden, insbesondere an einem Elektro- oder an einem Hybridfahrzeug und für Insassen oder für Servicefachkräfte bei der Instandsetzung eines derartigen Fahrzeuges besitzen daher alle metallischen Oberflächen der Bestandteile eines Batteriesystems, die technisch nicht gewartet werden müssen, eine Beschichtung oder Lackierung, die die vorgenannten Ereignisse lokal begrenzen kann.Lithium-ion battery cells, grouped together in a battery pack, for a battery system or a battery system assembled from multiple battery packs typically have metallic housing surfaces and the latter metallic housing parts prepared to receive the lithium-ion battery cells or battery cell packs. The lithium-ion battery cells usually have a cylindrical or a prismatic training. In the event of a short circuit, a chain reaction can severely damage the battery system, as with a charged traction battery, a current of up to 1000 A can flow for a short time. Short circuits can be brought about by processes in the battery system or by external influences, for example by a crash. In order to avoid consequential damage, in particular to an electric or hybrid vehicle and for occupants or for servicemen in the repair of such a vehicle, therefore, have all the metallic surfaces of the components of a battery system that need not be technically maintained, a coating or paint that the locally limit the aforementioned events.

Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird eine Lithium-Ionen-Batterie zur Verfügung gestellt, welche ein metallisches Gehäuse besitzt, wobei die Außenfläche des metallischen Gehäuses eine isolierende Beschichtung aufweist, die ein- oder mehrlagig aufgetragen und fest mit der metallischen Außenfläche der Batterie verbunden vorliegt.According to the invention, a lithium-ion battery is provided which has a metallic housing, wherein the outer surface of the metallic housing has an insulating coating which is applied in one or more layers and firmly connected to the metallic outer surface of the battery.
Die Beschichtung hat dabei den Vorteil, dass sie einfach auftragbar ist und im Bereich von Ecken und Radien dosierte Schichtdicken erreichbar sind, wodurch unterschiedliche Isolationsanforderungen erfüllt werden können. Es ist somit eine integrale, geschlossene elektrische Isolation eines gesamten Gehäuses einer Batterie, ohne Stoßstellen möglich und es tritt dabei keine Schwächung der elektrischen Isolation durch mehrlagige Übergänge oder Überlappbereiche, wie bei bisher bekannten Folienisolationen, auf. The coating has the advantage that it is easy to apply and in the range of corners and radii dosed layer thicknesses can be achieved, whereby different insulation requirements can be met. It is thus an integral, closed electrical insulation of an entire housing of a battery, without joints possible and there is no weakening of the electrical insulation by multilayer transitions or overlap areas, as in previously known foil insulation on.
Die Beschichtung des Gehäuses der Batterie ist so angelegt, dass einzelne Bereiche, bevorzugt die elektrischen Anschlüsse der Batterie oder die der Batteriezellen, von der Beschichtung ausgespart sind.The coating of the housing of the battery is designed so that individual areas, preferably the electrical terminals of the battery or the battery cells, are recessed from the coating.
Dadurch sind die elektrischen Anschlüsse, ohne vorherige Reinigungsarbeiten erreichbar und Batteriezellen oder Batteriemodule einer Batterie sind wartbar, wenn die elektrischen Verbindungen zwischen ihnen unterbrochen sind.As a result, the electrical connections, reachable without prior cleaning and battery cells or battery modules of a battery are maintainable, if the electrical connections between them are interrupted.
In die Beschichtung selbst sind unterschiedliche Werkstoffe eingebunden. Das bedeutet, dass es sich um Werkstoffe handelt, die neben der gezielt einstellbaren elektrischen Isolation auch vorteilhafterweise Eigenschaften generieren, die zur Verbesserung der Porendichte beitragen sowie optische und/oder haptische Effekte erbringen.Different materials are integrated in the coating itself. This means that they are materials which, in addition to the specifically adjustable electrical insulation, also advantageously generate properties which contribute to improving the pore density and provide optical and / or haptic effects.
Die unterschiedlichen Werkstoffe der Beschichtung umfassen in weiterer Ausgestaltung verschiedenartig pigmentierte Materialien, verschiedenartig elektrisch isolierende Materialien und/oder verschiedenartig Feuchtigkeit durchlässige Materialien. Dadurch kann eine Anpassung an lokal unterschiedliche Isolationsanforderungen vorgenommen werden und es ist möglich, Barriereschichten gegen das Eindringen von Feuchtigkeit von außen oder gegen Flüssigkeitsaustritt im Crashfall nach außen zu integrieren. In a further embodiment, the different materials of the coating comprise variously pigmented materials, variously electrically insulating materials and / or variously moisture-permeable materials. This allows an adaptation to locally different insulation requirements are made and it is possible to integrate barrier layers against the ingress of moisture from the outside or against liquid leakage in the event of a crash to the outside.
Die Batterie weist eine Beschichtung mit mindestens einem der folgenden Merkmale auf:
- – Lacke auf der Basis zweikomponentiger Epoxidharze,
- – Lacke auf der Basis zweikomponentiger, auch Lösungsmittel, enthaltender Epoxidharze,
- – Ein- oder Zweikomponentenlacke auf Wasserbasis,
- – Lacke auf unmodifizierter oder modifizierter Polyacrylatbasis,
- – UV-Lacksysteme,
- – eine nachverdichtete und/oder eine versiegelte Eloxalschicht, und
- – mit anorganischen Füllstoffen gefüllte organische Polymerlacke.
- Varnishes based on two-component epoxy resins,
- Varnishes based on two-component, including solvent-containing, epoxy resins,
- - one-component or two-component water-based coatings,
- Varnishes on unmodified or modified polyacrylate base,
- - UV varnish systems,
- A densified and / or sealed anodized layer, and
- - Organic polymer filled with inorganic fillers.
Eine derartige Beschichtung ist geeignet zur Erzielung einer elektrischen Isolation, einer verbesserten mechanischen Festigkeit und zum Erreichen eines verbesserten Penetrantionswiderstandes gegenüber Feuchtigkeit und Austritten von Flüssigkeit aus geschädigten Batteriezellen.Such a coating is suitable for achieving electrical insulation, improved mechanical strength, and for achieving improved penetration resistance to moisture and leakage of fluid from damaged battery cells.
In vorteilhafter Weiterbildung der Erfindung umfasst die Beschichtung einen mechanisch verstärkten Bereich, der mittels mehrerer, zueinander unterschiedlich strukturierter Schichten der Beschichtung ausgebildet ist oder einen Produktidentifikationsbereich aufweist.In an advantageous embodiment of the invention, the coating comprises a mechanically reinforced area which is formed by means of a plurality of differently structured layers of the coating or has a product identification area.
Damit gelingt es, mechanisch durch Reibung oder wechselnden Zug- und Druckbeanspruchungen ausgesetzten Flächen eines Gehäuses einer Batterie eine höhere Stabilität zu verleihen. Außerdem ist es von Vorteil, in diese Schichten eine pigmentierte Schicht zur Produktidentifikation einzubinden, wodurch ein Plagiatsschutz erzeugbar ist.This makes it possible to impart a higher stability mechanically exposed by friction or alternating tensile and compressive stress surfaces of a housing of a battery. In addition, it is advantageous to incorporate into these layers a pigmented layer for product identification, as a result of which plagiarism protection can be produced.
Die Batterie weist weiterhin eine Beschichtung auf, wobei sie Barriereschichten umfasst, bevorzugt Barriereschichten gegen Feuchtigkeit, gegen Wärme, mit erhöhter elektrischer Durchschlagsfestigkeit sind und hohem Durchgangswiderstand.The battery furthermore has a coating, wherein it comprises barrier layers, preferably barrier layers against moisture, against heat, with increased electrical breakdown resistance and high volume resistance.
Der neue Aspekt der Barriere gegen Wärme ist von großer Bedeutung, da insbesondere Lithium-Ionen-Batteriezellen vor extremen Temperaturschwankungen gesichert sein sollten.The new aspect of the barrier against heat is of great importance, since especially lithium-ion battery cells should be protected from extreme temperature fluctuations.
Die Batterie umfasst in ihrer Ausgestaltung und zur Steigerung ihrer Kapazität vorteilhafterweise mehrere Batteriezellen, die jeweils ein Metallgehäuse besitzen und die metallische Gehäuseoberfläche der Batterie durch die von benachbarten Batteriezellen wegweisenden Metallflächen der Batteriezellen gebildet wird.In its design and to increase its capacity, the battery advantageously comprises a plurality of battery cells, each of which has a metal housing and the metallic housing surface of the battery is formed by the metal surfaces of the battery cells facing away from adjacent battery cells.
Dadurch kann ein zusätzlich, die einzelnen Batteriezellen einfassendes Gehäuse eingespart und das Gewicht einer Batterie vermindert werden.As a result, an additional housing enclosing the individual battery cells can be saved and the weight of a battery can be reduced.
Das erfindungsgemäße Verfahren zur Herstellung einer Beschichtung von metallischen Batteriegehäusen umfasst mindestens eines der folgenden Verfahren:
- – pneumatische Zerstäubung eines Lackes,
- – Tauchlackieren,
- – Roll-, Tampon- oder Siebdruck,
- – ein elektrostatisches Sprühen,
- – thermisches Spritzen mit anorganischen Bestandteilen, und
- – Eloxieren mit anschließender Nachverdichtung und/oder Versieglung.
- - pneumatic atomization of a paint,
- - dip painting,
- - roll, tampon or screen printing,
- An electrostatic spraying,
- - Thermal spraying with inorganic components, and
- - Anodizing with subsequent densification and / or sealing.
Diese Möglichkeiten des Auftragens der Beschichtung erlauben eine dosierte Herstellung ihrer Schichtdicke, wobei die Haftung von einzelnen Schichten untereinander fest ist und die Integration von verschiedenartigen Werkstoffen darin unterschiedliche Eigenschaften, wie bereits genannt, hervorbringt.These coating application methods allow metered production of their layer thickness, whereby the adhesion of individual layers to one another is fixed and the integration of different materials therein produces different properties, as already mentioned.
In einer Ausgestaltung des Verfahrens werden einzelne Bereiche der zu beschichtenden Bereiche mittels Masken von der Beschichtung ausgenommen.In one embodiment of the method, individual regions of the regions to be coated are removed from the coating by means of masks.
Das bedeutet, dass im Bereich von elektrischen Anschlüssen der Batteriezellen oder im Bereich von funktionsbedingt freizuhaltenden Bereichen eine Abdeckung vorgenommen wird.This means that a cover is made in the range of electrical connections of the battery cells or in the area of areas to be kept free of function.
Erfindungsgemäß ist es sinnvoll, dass ein Kraftfahrzeug mit einer Batterie ausgestattet ist, die an ihren metallischen Flächen durch ein Beschichtungsverfahren von außen beschichtet ist, wobei die Batterie mit einem Antriebssystem eines Kraftfahrzeuges verbunden ist. According to the invention, it makes sense that a motor vehicle is equipped with a battery which is coated on its metallic surfaces by a coating process from the outside, wherein the battery is connected to a drive system of a motor vehicle.

In der
Die Beschichtung in mehreren Lagen hat auch den Vorteil, dass neben funktionsbestimmenden Schichten, wie vorgenannt, auch pigmentierte Kennzeichnungen zur Darstellung eines Hersteller spezifischen Produktes aufgebracht werden können. Außerdem ist es möglich mechanische plötzlich auftretende Belastungen mittels Schichten mit Dämpfungseigenschaften aufzufangen, damit in Crashsituationen eine Freilegung des Batterieinnern vermieden wird.The coating in several layers also has the advantage that in addition to function-determining layers, as mentioned above, pigmented markings can also be applied to represent a manufacturer-specific product. In addition, it is possible to absorb mechanical loads occurring suddenly by means of layers with damping properties, so that an exposure of the battery interior is avoided in crash situations.
