Abstract

A cell contacting system for an electro-chemical device includes a plurality of electro-chemical cells and a current line system, wherein the cell contacting system includes a signal line system having signal lines for connecting a respective signal source to a signal line termination or to a monitoring device of the cell contacting system and a carrier element which carries the signal line system. The cell contacting system further includes at least one signal-line-system-side positioning element which is fixed to a signal line of the signal line system and at least one carrier-element-side positioning element which is fixed at least temporarily to the carrier element, wherein the signal-line-system-side positioning element is connected to the carrier-element-side positioning element at least temporarily in such a way that the signal-line-system-side positioning element is positioned in a desired position relative to a cell connector or a current termination of the current line system.
