Die Erfindung betrifft eine vormontierte Einheit für ein Batteriemodul gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a preassembled unit for a battery module according to the preamble of patent claim 1.
Stand der TechnikState of the art
Batteriemodule für Elektro- und Hybridfahrzeuge sind üblicherweise aus einer Vielzahl von nebeneinander angeordneten individuellen Einzelzellen aufgebaut.Battery modules for electric and hybrid vehicles are usually constructed from a plurality of juxtaposed individual individual cells.
Diese Einzelzellen weisen an ihrer Oberseite Anschlüsse bzw. Pole auf. Um hieraus ein Batteriepaket zu bilden, müssen die Einzelzellen mit Zellverbindern elektrisch in Reihe geschaltet werden.These individual cells have on their top terminals or poles. To form a battery pack from this, the individual cells must be electrically connected in series with cell connectors.
Diese Zellverbinder bestehen üblicherweise aus länglichen, ca. 1–2 mm dicken Kupferblechstreifen, die an zwei Seiten jeweils ein Loch zur Schraubbefestigung aufweisen.These cell connectors usually consist of elongated, approximately 1-2 mm thick copper sheet strips, each having a hole for screw fastening on two sides.
Aus Gründen einer effizienten und sicheren Montage ist es das Bestreben der Hersteller von Batteriemoduln, alle Zellverbinder eines Batteriemoduls als vormontierte Einheit geeignet angeliefert zu erhalten. Dies erlaubt, die Zellverbinder in einem Arbeitsgang passgenau auf ein Batteriemodul aufzusetzen.For reasons of efficient and safe assembly, it is the endeavor of the manufacturers of battery modules to receive all the cell connectors of a battery module as a preassembled unit. This allows the cell connectors in a single operation fit on a battery module.
Derzeit werden vormontierte Einheiten als zweiteilige Vorrichtungen aus Kunststoff, welche einen Boden und einen Deckel umfassen, konstruiert.Currently, pre-assembled units are constructed as two-piece plastic devices comprising a bottom and a lid.
Eine Kunststoffplatte weist Ausnehmungen für die Zellverbinder auf, wobei die Zellverbinder mit elastischem Kunststoff umspritzt werden.A plastic plate has recesses for the cell connectors, wherein the cell connectors are encapsulated with elastic plastic.
Vor diesem Hintergrund bestehen weitere Anforderungen an eine solche vormontierte Einheit. Sie sollte eine geringe Bauhöhe aufweisen, insbesondere nicht wesentlich dicker als ein Zellverbinder selbst sein. Sie sollte wenig Material aufweisen, um ein geringes Gewicht zu zeigen. Es sollte ein Toleranzausgleich sowohl während der Montage als auch im Betrieb möglich sein. Die vormontierte Einheit sollte überdies elektrisch isolieren.Against this background, there are further requirements for such a preassembled unit. It should have a low height, in particular not be much thicker than a cell connector itself. It should have little material to show a low weight. A tolerance compensation should be possible during assembly as well as during operation. The preassembled unit should moreover be electrically insulated.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, eine vormontierte Einheit der eingangs genannten Art derart auszugestalten und weiterzubilden, dass diese nach einfacher Fertigung bei kompakter Bauweise ein geringes Gewicht und ein hohes Ausgleichsvermögen im Hinblick auf bauliche Gegebenheiten eines Batteriemoduls zeigt.The invention is therefore based on the object, a preassembled unit of the type mentioned in such a way and further develop that it shows a simple design with a compact design, a low weight and a high level of compensation with regard to structural conditions of a battery module.
Die vorliegende Erfindung löst die zuvor genannte Aufgabe durch eine vormontierte Einheit mit den Merkmalen des Patentanspruchs 1.The present invention solves the aforementioned object by a preassembled unit having the features of patent claim 1.
Eine erfindungsgemäße vormontierte Einheit für ein Batteriemodul umfasst eine Kunststoffplatte und elektrisch leitfähige Zellverbinder, wobei in der Kunststoffplatte Ausnehmungen ausgebildet sind, in welchen die Zellverbinder aufgenommen sind, und wobei die Zellverbinder Durchgänge für Pole von Einzelzellen eines Batteriemoduls aufweisen.A preassembled unit for a battery module according to the invention comprises a plastic plate and electrically conductive cell connectors, wherein in the plastic plate recesses are formed, in which the cell connectors are accommodated, and wherein the cell connectors have passages for poles of single cells of a battery module.
Erfindungsgemäß ist vorgesehen, dass die Kunststoffplatte auf einer Seite Haltemittel aufweist, welche die Zellverbinder in den Ausnehmungen zurückhalten, wobei auf der anderen Seite der Kunststoffplatte eine Kunststofffolie vorgesehen ist, welche die Zellverbinder in den Ausnehmungen hält.According to the invention it is provided that the plastic plate has on one side holding means which retain the cell connectors in the recesses, wherein on the other side of the plastic plate, a plastic film is provided, which holds the cell connectors in the recesses.
Erfindungsgemäß ist zunächst erkannt worden, dass der Einsatz einer Kunststoffplatte, die genau so dick ist wie ein Zellverbinder, zu einer besonders flachen vormontierten Einheit führt. Erfindungsgemäß sind Ausnehmungen für Zellverbinder vorgesehen, in denen die Zellverbinder mit Spiel aufgenommen werden können. Konkret ist hierbei erkannt worden, dass auf einer Seite der Kunststoffplatte Haltemittel so angebracht werden können, dass die Zellverbinder zwar nicht durch eine Ausnehmung durchfallen, aber beweglich in dieser aufgenommen sind. Auf der anderen Seite der Kunststoffplatte wird eine vorgestanzte Kunststofffolie aufgebracht, welche die Zellverbinder in der jeweiligen Ausnehmung hält. Ausstanzungen in der Kunststofffolie erlauben den elektrischen Zugriff auf Schraubflächen eines Zellverbinders. Insoweit ist eine vormontierte Einheit angegeben, welche nach einfacher Fertigung bei kompakter Bauweise ein geringes Gewicht und ein hohes Ausgleichsvermögen im Hinblick auf bauliche Gegebenheiten eines Batteriemoduls zeigt.According to the invention, it has first been recognized that the use of a plastic plate, which is just as thick as a cell connector, leads to a particularly flat preassembled unit. According to the invention, recesses are provided for cell connectors in which the cell connectors can be received with play. Specifically, it has been recognized here that on one side of the plastic plate holding means can be mounted so that the cell connectors do not fall through a recess, but are movably received in this. On the other side of the plastic plate, a pre-cut plastic film is applied, which holds the cell connectors in the respective recess. Punching in the plastic film allow electrical access to screw surfaces of a cell connector. In that regard, a preassembled unit is given, which shows a simple design with a compact design, a low weight and a high level of compensation in terms of structural conditions of a battery module.
Folglich ist die eingangsgenannte Aufgabe gelöst.Consequently, the above-mentioned object is achieved.
Die Haltemittel könnten als stegartige Haltenasen ausgebildet sein. Schmale Haltenasen erlauben einen problemlosen Zugriff auf die Zellverbinder, um eine elektrische Kontaktierung herzustellen.The holding means could be designed as web-like retaining lugs. Narrow retaining lugs allow easy access to the cell connectors to make electrical contact.
Die Kunststofffolie könnte Zungen aufweisen, welche die Zellverbinder teilweise überdecken. Eine Kunststofffolie erhöht die Stärke bzw. Dicke der Einheit nahezu nicht. Die Kunststofffolie kann aufgeklebt sein.The plastic film could have tongues that partially cover the cell connectors. A plastic film almost does not increase the thickness or thickness of the unit. The plastic film can be glued on.
Zur Signalverarbeitung bzw. -verdrahtung könnte eine FPC („Flexible Printed Circuit”) oder flexible Leiterplatte an der vormontierten Einheit angeordnet werden.For signal processing or wiring, an FPC (Flexible Printed Circuit) or flexible printed circuit board could be placed on the preassembled unit.
Es gibt nun verschiedene Möglichkeiten, die Lehre der vorliegenden Erfindung in vorteilhafter Weise auszugestalten und weiter zu bilden. Dazu ist einerseits auf die nachgeordneten Ansprüche, andererseits auf die nachfolgende Erläuterung eines bevorzugten Ausführungsbeispiels der erfindungsgemäßen vormontierten Einheit anhand der Zeichnung zu verweisen.There are now various possibilities for embodying and further developing the teaching of the present invention in an advantageous manner.
