Abstract
Bei einem Verfahren zur Herstellung eines Batteriegehäuses (20) umfasst das Batteriegehäuse (20) ein mit einer Karosserie (10) eines Fahrzeugs (12) verbundenes Batteriegehäuseteil (30, 32) und einen Deckel (50). Der Deckel (50) hat eine Kontaktfläche (52), und das Batteriegehäuseteil (30, 32) hat eine Kontaktgegenfläche (34). Das Verfahren hat die folgenden Schritte: A) Der Deckel (50) wird am Batteriegehäuseteil (30, 32) lösbar befestigt, so dass die Kontaktfläche (52) des Deckels und die Kontaktgegenfläche (34) des Batteriegehäuseteils (30, 32) in einem Kontaktbereich (90) aneinander liegen, B) eine kathodische Tauchlackierung des Batteriegehäuseteils (30, 32) und des am Batteriegehäuseteil (30, 32) befestigten Deckels (50) wird durchgeführt, um den Kontaktbereich (90) zumindest bereichsweise frei von Tauchlack zu halten.In a method of manufacturing a battery case (20), the battery case (20) includes a battery case part (30, 32) connected to a body (10) of a vehicle (12) and a lid (50). The lid (50) has a contact surface (52), and the battery housing part (30, 32) has a contact mating surface (34). The method has the following steps: A) The cover (50) is releasably attached to the battery housing part (30, 32) such that the contact surface (52) of the cover and the contact mating surface (34) of the battery housing part (30, 32) in a contact region (B) a cathodic dip painting of the battery housing part (30, 32) and of the battery housing part (30, 32) attached lid (50) is performed to keep the contact area (90) at least partially free of dip paint.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Batteriegehäuses. The invention relates to a method for producing a battery case.
Bei heutigen Elektrofahrzeugen, die mit elektrischer Energie angetrieben werden, also beispielsweise Kraftfahrzeugen, Schienenfahrzeugen oder Wasserfahrzeugen, wird die Antriebsenergie häufig in Traktionsbatterien im Fahrzeug gespeichert. Traktionsbatterien sind Energiespeicher, die zum Antrieb von Elektrofahrzeugen dienen, und sie werden auch als Traktionsakkus oder Antriebsbatterien bezeichnet. Es handelt sich bevorzugt um Hochvolt-Batterien, und diesen sind üblicherweise Elektronikkomponenten zugeordnet, die elektromagnetische Wellen erzeugen. Diese elektromagnetischen Wellen sollen durch das Batteriegehäuse abgeschirmt werden. In today's electric vehicles that are powered by electrical energy, such as motor vehicles, rail vehicles or watercraft, the drive energy is often stored in traction batteries in the vehicle. Traction batteries are energy storage devices used to drive electric vehicles, and are also referred to as traction batteries or traction batteries. These are preferably high-voltage batteries, and these are usually associated with electronic components that generate electromagnetic waves. These electromagnetic waves should be shielded by the battery case.

Es ist daher eine Aufgabe der Erfindung, ein neues Verfahren zur Herstellung eines Batteriegehäuses bereitzustellen. It is therefore an object of the invention to provide a new method of manufacturing a battery case.
Diese Aufgabe wird gelöst durch den Gegenstand des Anspruchs 1. This object is achieved by the subject matter of claim 1.
Man erhält so einen zumindest bereichsweise tauchlackfreien Kontakt zwischen dem Deckel und dem Batteriegehäuseteil. This gives an at least partially dip-free contact between the lid and the battery case part.
Gemäß einer bevorzugten Ausführungsform werden der Deckel und das Batteriegehäuseteil durch eine Befestigungsklammer gegeneinander gedrückt. Dies ist eine einfache, schnell anbringbare und wieder lösbare Befestigung. According to a preferred embodiment, the lid and the battery housing part are pressed against each other by a mounting bracket. This is a simple, quick to attach and detachable attachment.
Die Befestigungsklammer ist bevorzugt an der Oberfläche nicht-metallisch ausgebildet. Hierdurch wird eine Beschichtung der Befestigungsklammer zumindest vermindert. The mounting bracket is preferably non-metallic on the surface. As a result, a coating of the mounting bracket is at least reduced.
Gemäß einer bevorzugten Ausführungsform ist mindestens ein Verbindungsmittel vorgesehen, und der Deckel wird über das Verbindungsmittel am Batteriegehäuseteil befestigt. Das Verbindungsmittel ist bevorzugt als Schraubverbindung oder als Schnappverbindung ausgebildet. Hiermit können der Deckel und das Batteriegehäuse vorteilhaft miteinander verbunden werden, sowohl vor der Beschichtung als auch danach. According to a preferred embodiment, at least one connecting means is provided, and the lid is fastened via the connecting means on the battery housing part. The connecting means is preferably designed as a screw connection or as a snap connection. Hereby, the lid and the battery case can be advantageously connected to each other, both before the coating and afterwards.
Gemäß einer bevorzugten Ausführungsform sind die Kontaktfläche und die Kontaktgegenfläche metallisch ausgebildet. Hierdurch wird eine gute elektrische Verbindung zwischen den Bauteilen ermöglicht. According to a preferred embodiment, the contact surface and the contact mating surface are formed metallic. This allows a good electrical connection between the components.
Gemäß einer bevorzugten Ausführungsform weisen das Batteriegehäuseteil und der Deckel einen metallischen Werkstoff auf. Somit kann das Batteriegehäuse als Faradayscher Käfig wirken und elektromagnetische Strahlung abschirmen. According to a preferred embodiment, the battery housing part and the lid on a metallic material. Thus, the battery case can act as a Faraday cage and shield electromagnetic radiation.
Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den im Folgenden beschriebenen und in der Zeichnung dargestellten, in keiner Weise als Einschränkung der Erfindung zu verstehenden Ausführungsbeispielen, sowie aus den Unteransprüchen. Es zeigt Further details and advantageous developments of the invention will become apparent from the hereinafter described and illustrated in the drawings, in no way as a limitation of the invention to be understood embodiments, and from the dependent claims. It shows
