Abstract

A battery cell with a galvanic cell, a first semiconductor switching element, a first cell connector electrically coupled directly to a first potential connector of the galvanic cell, and a second cell connector electrically coupled to a second potential connector of the galvanic cell via the first semiconductor switching element. The battery cell further has a third cell connector electrically coupled to the second potential connector of the galvanic cell, a second semiconductor switching element, and a fourth cell connector electrically coupled to the first potential connector of the galvanic cell via the second semiconductor switching element. A third semiconductor switching element is connected between the third cell connector and the fourth cell connector which primarily serves to switch individual battery cells out of the system regardless of the (activation or deactivation) state of the predecessor as well as successor cells.
