Title
(DE) ANORDNUNG FÜR ZELLEN ZUR SPEICHERUNG ELEKTRISCHER ENERGIE MIT FEDERKONTAKTELEMENT
(EN) ARRANGEMENT FOR CELLS FOR STORING ELECTRICAL ENERGY HAVING A SPRING CONTACT ELEMENT
(FR) AGENCEMENT DE CELLULES D'ACCUMULATION D'ÉNERGIE ÉLECTRIQUE À ÉLÉMENT DE CONTACT À RESSORT
Abstract
(DE) Die Erfindung betrifft eine Anordnung für Zellen (4) zur Speicherung elektrischer Energie, mit mindestens zwei Zellen (4), wobei die mindestens zwei Zellen (4) jeweils eine Axialrichtung (6), einen umfangsseitigen Bereich (8) und zwei Stirnseiten (10, 12) aufweisen, wobei die Stirnseiten (10, 12) einander in Axialrichtung (6) gegenüber liegend angeordnet sind mindestens ein Polbereich (14, 18) an einer Stirnseite (10, 12) vorgesehen ist, mit mindestens einer Verbindungsplatte (20, 24, 48), wobei die mindestens zwei Zellen (4) an der mindestens einen Verbindungsplatte (20, 24, 48) angeordnet sind, wobei Kontaktelemente (22) zwischen der mindestens einen Verbindungsplatte (20, 24, 48) und den Polbereichen (14, 18) der mindestens zwei Zellen (4) für einen elektrischen Kontakt vorgesehen sind. Die Aufgabe, eine Anordnung anzugeben, welche eine einfache und sichere Kontaktierung von Zellen (4) ermöglicht und insbesondere die Nachteile aus dem Stand der Technik vermindert, wird dadurch gelöst, dass mindestens eines der Kontaktelemente (22) welches in Kontakt zu einer Zelle (4) steht, als Federkontaktelement ausgestaltet ist, welches in einem verformten Zustand eine Federkraft zur Anlage an dem jeweiligen Polbereich (14, 18) der mindestens zwei Zellen (4) zur Bildung des elektrischen Kontakts zwischen der mindestens einen Verbindungsplatte (20, 24, 48) und Polbereich (14, 18) bereitstellt.
(EN) The invention relates to an arrangement for cells (4) for storing electrical energy, comprising at least two cells (4), the at least two cells (4) each having an axial direction (6), a circumferential region (8), and two end faces (10, 12), the end faces (10, 12) being arranged opposite one another in the axial direction (6) and at least one terminal region (14, 18) being provided at one end face (10, 12), and comprising least one connection plate (20, 24, 48), the at least two cells (4) being arranged on the at least one connection plate (20, 24, 48), contact elements (22) being provided between the at least one connection plate (20, 24, 48) and the terminal regions (14, 18) of the at least two cells (4) for electrical contact. The problem of providing an arrangement which enables simple and reliable contacting of cells (4) and in particular mitigates the disadvantages from the prior art is solved in that at least one of the contact elements (22) which is in contact with a cell (4) is designed as a spring contact element which, in a deformed state, provides a spring force for bearing against the corresponding terminal region (14, 18) of the at least two cells (4) to form the electrical contact between the at least one connection plate (20, 24, 48) and terminal region (14, 18).
(FR) L’invention concerne un agencement de cellules (4) d’accumulation d’énergie électrique, pourvu d’au moins deux cellules (4), les au moins deux cellules (4) comportant respectivement une direction axiale (6), une zone périphérique (8) et deux faces avant (10, 12), les faces avant (10, 12) étant agencées l’une par rapport à l’autre dans la direction axiale (6) de manière à se faire face, au moins une zone de pôles (14, 18) étant installée au niveau d’une face avant (10, 12), d’au moins une plaque de connexion (20, 24, 48), les au moins deux cellules (4) étant agencées au niveau de la plaque ou des plaques de connexion (20, 24, 48), des éléments de contact (22) étant installés entre la ou les plaques de connexion (20, 24, 48) et les zones de pôles (14, 18) des au moins deux cellules (4) pour un contact électrique. La solution selon l’invention afin de mettre en œuvre un agencement, lequel permet une mise en contact simple et sûre de cellules (4) et en particulier réduit les inconvénients de l’état de la technique, consiste en ce qu’au moins un des éléments de contact (22), lequel se trouve en contact avec une cellule (4), est réalisé sous forme d’un élément de contact à ressort, lequel exerce, dans un état déformé, une force élastique qui s’applique à la zone de pôles (14, 18) respective des au moins deux cellules (4) pour l’établissement du contact électrique entre la ou les plaques de connexion (20, 24, 48) et la zone de pôles (14, 18).
