Title: CELL CONTACTING SYSTEM FOR AN ELECTROCHEMICAL DEVICE
Abstract:
To create a cell contacting system for an electrochemical device comprising a plurality of cell groups, which each comprise one or more electrochemical cells, wherein each electrochemical cell has a first cell terminal and a second cell terminal, wherein the electrochemical cells follow each other along a longitudinal direction, the first cell terminals follow each other along the longitudinal direction in a first cell terminal region of the electrochemical device and the second cell terminals follow each other along the longitudinal direction in a second cell terminal region of the electrochemical device, wherein the cell contacting system comprises at least one cell connector for the electrically conductive connection of cell terminals of a first cell group to cell terminals of a second cell group, which system also reliably permits a relative movement between the cell terminals to be electrically connected to each other even if the distances to the subsequent cell terminals are small, according to the invention at least one cell connector extends obliquely with respect to the longitudinal direction of cell terminals of the first cell group in the first cell terminal region to cell terminals of the second cell group in the second cell terminal region.
