1. A cell contacting system for an electrochemical device which comprises a plurality of cell groups that each comprise one or a plurality of electrochemical cells,
wherein each electrochemical cell has a first cell terminal and a second cell terminal, said first cell terminal and said second cell terminal ending on substantially planar contact surfaces lying in a contact plane of the electrochemical device,
wherein the electrochemical cells follow each other along a longitudinal direction of the electrochemical device,
the first cell terminals of the electrochemical cells follow each other along the longitudinal direction in a first cell terminal region of the electrochemical device, and
the second cell terminals of the electrochemical cells 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 electrically conductively connecting at least one cell terminal of a first cell group to at least one cell terminal of a second cell group,
wherein the cell connector comprises a first contact region for contacting the at least one cell terminal of the first cell group and a second contact region for contacting the at least one cell terminal of the second cell group,
wherein at least one cell connector extends obliquely to the longitudinal direction from at least one cell terminal of the first cell group in the first cell terminal region to at least one cell terminal of the second cell group in the second cell terminal region,
wherein the at least one cell connector comprises an intermediate region connecting the first contact region and the second contact region to each other, the longitudinal axis of which intermediate region is aligned obliquely to the longitudinal direction of the electrochemical device, and
wherein the at least one cell connector is provided with beads or angular bends running in parallel to the longitudinal direction of the electrochemical device and obliquely to the longitudinal axis of the intermediate region,
said beads or angular bends being configured such that the intermediate region of the at least one cell connector runs at a distance from the contact plane of the electrochemical device which is different from the distances from the contact plane of the electrochemical device at which the first contact region and the second contact region runs, respectively.
