Description
Die Erfindung betrifft ein Verbindungselement zur elektrischen Verschaltung von Einzelzellen, einen Zellblock für eine elektrische Batterie und eine elektrische Batterie, umfassend mehrere solche Zellblöcke.The invention relates to a connection element for the electrical connection of individual cells, a cell block for an electric battery and an electric battery comprising a plurality of such cell blocks.
Aus der
Weiterhin sind aus dem Stand der Technik allgemein Zellblöcke für elektrische Batterien mit jeweils einer Mehrzahl elektrisch miteinander verschalteter Einzelzellen bekannt. Die elektrische Verschaltung der Einzelzellen erfolgt mittels Verbindungselementen, welche als massive und jeweils mit elektrischen Polen der Einzelzellen punktverschweißte, hochstromfähige Zellverbinder ausgebildet sind. Die Zellverbinder sind dabei einstückig ausgebildet und verbinden jeweils mehr als zwei Einzelzellen elektrisch miteinander.Furthermore, cell blocks for electric batteries, each having a plurality of individual cells interconnected electrically, are generally known from the prior art. The electrical interconnection of the individual cells takes place by means of connecting elements, which are designed as solid and each point-welded with high voltage cell poles of the individual cells. The cell connectors are integrally formed and connect more than two individual cells each other electrically.
Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Verbindungselement zur elektrischen Verschaltung von Einzelzellen, einen verbesserten Zellblock für eine elektrische Batterie und eine verbesserte elektrische Batterie anzugeben.The invention is based on the object to provide a comparison with the prior art improved connection element for the electrical interconnection of single cells, an improved cell block for an electric battery and an improved electric battery.
Hinsichtlich des Verbindungselements wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale, hinsichtlich des Zellblocks durch die im Anspruch 7 angegebenen Merkmale und hinsichtlich der elektrischen Batterie durch die im Anspruch 10 angegebenen Merkmale gelöst.With regard to the connecting element, the object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Das Verbindungselement zur elektrischen Verschaltung von Einzelzellen umfasst erfindungsgemäß eine Stromsammelschiene und einen Zellverbinder, wobei die Stromsammelschiene und der Zellverbinder elektrisch miteinander verbunden und aneinander angeordnet sind, der Zellverbinder zur elektrischen Kontaktierung von mehr als zwei Einzelzellen ausgebildet ist und sich die Stromsammelschiene zumindest über eine Länge des Zellverbinders erstreckt.According to the invention, the connecting element for electrically interconnecting individual cells comprises a busbar and a cell connector, wherein the busbar and the cell connector are electrically connected and arranged to one another, the cell connector is designed for electrical contacting of more than two individual cells and the busbar is at least over a length of Cell connector extends.
Mittels des Verbindungselements und der einstückigen Ausbildung von Stromsammelschiene und Zellverbinder für mehr als zwei Einzelzellen wird gegenüber separaten Zellverbindern für jeweils zwei Einzelzellen eine signifikante Verringerung einer Teileanzahl und somit eine wesentlich vereinfachte Handhabung während der Montage des Verbindungselements und dessen Montage an den Einzelzellen erreicht. Insbesondere werden eine aufwändige Positionierung und Ausrichtung mehrerer Zellverbinder zur Stromsammelschiene vermieden und ein Montageaufwand sowie Material- und Teilekosten können gesenkt werden.By means of the connecting element and the integral formation of current busbar and cell connector for more than two individual cells, a significant reduction of a number of parts and thus a considerably simplified handling during assembly of the connecting element and its mounting to the individual cells is achieved compared to separate cell connectors for every two individual cells. In particular, a complex positioning and alignment of multiple cell connectors are avoided for power bus and a mounting effort and material and parts costs can be reduced.
