Abstract
The present disclosure relates to a device for monitoring and balancing the cell voltages of at least two energy storage cells, which are electrically connected in series, of a multi-cell energy storage stack having at least one energy storage element, a voltage measuring unit, a first combinatorial circuit that is connected to each energy storage cell and the voltage measuring unit, a second combinatorial circuit that is connected to the energy storage element, the voltage measuring unit, and the first combinatorial circuit, and controls a control unit, which is connected to the voltage measuring unit and the first and second combinatorial circuit.
