Patent ID: 8574008

Claim:
Battery cell connector, comprising: a first terminal part adapted for connecting to a battery terminal of a first battery, a second terminal part, a connecting part which is arranged between the two terminal parts and which electrically connects the terminal parts to one another, wherein the first terminal part is formed at least on the side (A) facing a battery terminal from a first electrically conductive material, and wherein a flat piece, which is formed for connecting to a second battery terminal and which is formed at least on the side (A) facing the second battery terminal from a second electrically conductive material different from the first electrically conductive material, is arranged materially bonded on the second terminal part, wherein the connecting part comprises a Z-shaped longitudinal cross-section, wherein the Z-shaped longitudinal cross-section includes a central web which is inclined by no more than 20° with respect to perpendicular to the flat piece, wherein the Z-shaped longitudinal cross-section is corrugated such that the connecting part is elastically deformable in at least two perpendicular spatial directions, wherein the connecting part comprises at least one corrugation ridge and one corrugation trough in longitudinal cross-section, and wherein the corrugation ridge and the corrugation trough respectively lie outside the plane of at least one of the terminal parts.
