Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Gehäuses für einen elektrochemischen Energiespeicher.The invention relates to a method for producing a housing for an electrochemical energy store.
Aus dem Stand der Technik ist, wie in der
Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zur Herstellung eines Gehäuses für einen elektrochemischen Energiespeicher anzugeben.The invention is based on the object of specifying a method for producing a housing for an electrochemical energy store which is improved over the prior art.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zur Herstellung eines Gehäuses für einen elektrochemischen Energiespeicher mit den Merkmalen des Anspruchs 1.The object is achieved according to the invention by a method for producing a housing for an electrochemical energy store with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.
In einem Verfahren zur Herstellung eines Gehäuses für einen elektrochemischen Energiespeicher wird erfindungsgemäß auf eine Innenseite des Gehäuses eine wachsartige Schutzschicht, insbesondere mindestens ein Wachs, mindestens ein Paraffin und/oder mindestens ein ähnlicher, insbesondere wachsartiger und/oder paraffinartiger, Kohlenwasserstoff aufgesprüht.In a method for producing a housing for an electrochemical energy store, according to the invention, a wax-like protective layer, in particular at least one wax, at least one paraffin and / or at least one similar, in particular waxy and / or paraffin-like, hydrocarbon is sprayed onto an inside of the housing.
Der elektrochemische Energiespeicher ist insbesondere eine Traktionsbatterie, insbesondere eine so genannte Hochvoltbatterie, für ein Fahrzeug, insbesondere für ein Elektrofahrzeug, Hybridfahrzeug oder Brennstoffzellenfahrzeug, welche insbesondere zur elektrischen Energieversorgung mindestens einer elektrischen Antriebsmaschine zum Antrieb des Fahrzeugs vorgesehen ist.The electrochemical energy store is in particular a traction battery, in particular a so-called high-voltage battery, for a vehicle, in particular for an electric vehicle, hybrid vehicle or fuel cell vehicle, which is provided in particular for the electrical energy supply of at least one electric drive machine to drive the vehicle.
Insbesondere bei derartigen elektrochemischen Energiespeichern können elektrische Kurzschlüsse auftreten, welche durch elektrisch leitende Restschmutz-Partikel verursacht werden, die beispielsweise während eines Produktionsprozesses des Gehäuses und/oder des elektrochemischen Energiespeichers entstanden sind. Durch das erfindungsgemäße Verfahren können solche gegebenenfalls im Gehäuse vorhandenen Restschmutz-Partikel, die, gegebenenfalls nach einer zuvor erfolgten konventionellen Reinigung des Gehäuses, noch vorhanden sind, mittels der wachsartigen Schutzschicht immobilisiert und damit unschädlich gemacht werden, da sie an dieser wachsartigen Schutzschicht anhaften. Sie werden beispielsweise ähnlich einer eine klebrige Oberfläche aufweisenden Fliegenfalle durch diese Schutzschicht eingefangen. Dadurch können solche durch die Restschmutz-Partikel verursachten elektrischen Kurzschlüsse vermieden werden, da diese Restschmutz-Partikel nicht an stromführende Teile des elektrochemischen Energiespeichers gelangen können.In particular in the case of such electrochemical energy stores, electrical short circuits can occur, which are caused by electrically conductive residual dirt particles that have arisen, for example, during a production process for the housing and / or the electrochemical energy store. With the method according to the invention, any residual dirt particles that may be present in the housing and that may still be present after conventional cleaning of the housing, can be immobilized by means of the wax-like protective layer and thus rendered harmless, since they adhere to this waxy protective layer. They are captured by this protective layer, for example, similar to a fly trap having a sticky surface. As a result, such electrical short circuits caused by the residual dirt particles can be avoided, since these residual dirt particles cannot reach current-carrying parts of the electrochemical energy store.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention are explained in more detail below with reference to a drawing.
Dabei zeigt:
-
1 schematisch eine Schnittdarstellung einer Gehäusewand eines Gehäuses für einen elektrochemischen Energiespeicher.
-
1 schematically a sectional illustration of a housing wall of a housing for an electrochemical energy store.
Gegenmaßnahmen, um solche elektrischen Kurzschlüsse zu verhindern, sind beispielsweise eine intensive und kostspielige Reinigung des Gehäuses
Um diese Nachteile zu vermeiden, ist daher ein Verfahren zur Herstellung des Gehäuses
Durch diese kostengünstige Vorgehensweise wird erreicht, dass die elektrisch leitenden Restschmutz-Partikel in dieser Schutzschicht
Die beschriebene kostengünstige Maßnahme kann vorteilhafterweise viele kostenintensive Maßnahmen, insbesondere die oben genannten Maßnahmen, ersetzen. Des Weiteren werden dadurch kleinere Abstände zwischen den Bauteilen des elektrochemischen Energiespeichers und somit eine höhere Energiedichte des elektrochemischen Energiespeichers ermöglicht, wodurch dessen Bauraumbedarf bei gleichem Energieinhalt geringer ist oder wodurch bei gleichen Abmessungen ein größerer Energieinhalt des elektrochemischen Energiespeichers ermöglicht wird. Dadurch wird ein erheblicher Wettbewerbsvorteil erreicht.The cost-effective measure described can advantageously replace many cost-intensive measures, in particular the measures mentioned above. Furthermore, this enables smaller distances between the components of the electrochemical energy store and thus a higher energy density of the electrochemical energy store, which means that its installation space requirement is lower with the same energy content or whereby a greater energy content of the electrochemical energy store is made possible with the same dimensions. This creates a significant competitive advantage.
