Abstract

A cell having a galvanic cell. The galvanic cell has a first and a second electrode connection. The first electrode connection is connected to a first cell connection and the second electrode connection is connected to a second cell connection. The battery cell has a third and a fourth cell connection and at least four semiconductor switching elements, by which the electrode connections, depending on a respective switching state of the semiconductor switching elements, can each be electrically coupled to the third or the fourth of the cell connections. These are primarily used to remove and add individual battery cells from or to the system and/or to connect cells in parallel, independently of the (activation or deactivation) state of the preceding and following cells.
