Cell contacting system for an electro-chemical device and method for producing a cell contacting system

An electro-chemical device, comprising a plurality of electro-chemical cells and a cell contacting system which comprises

• a signal line system having one or more signal lines for connecting a respective signal source to a signal line termination or to a monitoring device of the cell contacting system in electrically conductive manner and
• a carrier element which carries the signal line system,
• wherein the cell contacting system comprises 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 at least temporarily to the carrier-element-side positioning element 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,
• wherein the cell connectors are arranged over the cell terminals of the electro-chemical cells that are to be connected to one another in a Z-direction in the assembled state of the cell contacting system,
• wherein the signal-line-system-side positioning element comprises a contact region by means of which the signal-line-system-side positioning element is fixed to the associated cell connector or current termination,
• a terminal region by means of which the signal-line-system-side positioning element is fixed to the associated signal line, and
• a deformation region which is arranged between the contact region and the terminal region, and
• wherein the deformation region is deformable in such a way that the contact region of the signal-line-system-side positioning element is movable relative to the terminal region along the Z-direction.
