Abstract
A voltage tap element configured to tap off the voltage of a battery cell of a battery unit by an electronics unit, a cell supervisory unit having such voltage tap elements, and a battery unit having such a cell supervisory unit, and methods for producing the cell supervisory unit and the battery unit. The voltage tap element is designed as a clip composed of a first metal, with a first end of the clip having a first contact region which establishes a operative connection to the electronics unit, and a second end of the clip having a second contact region for establishing a connection to the battery cell. In the first contact region, the clip is permanently connected to an intermediate piece which is composed of a second metal which differs from the first metal. The intermediate piece is configured for operative connection to the electronics unit by a solder connection using SMD technology.
