Cell connector for a battery system

The connector (3) has a cutting voltage clamp (7) for tapping off electric voltage, and two portions that are made of different materials and firmly bonded connected with one another. The cutting voltage clamp is permanently connected with one of the portions of the cell connector in an electrical and conductive manner by a roll bonding process. The cutting voltage clamp comprises a projection that is inserted into the cell connector. A measuring conduit (4) is connected with an electronic unit (5) by the cutting voltage clamp. An independent claim is also included for a battery system.
