A voltage stabilization apparatus () for a motor vehicle electrical system to stabilize at least one voltage-sensitive consumer () is proposed. The voltage stabilization apparatus is distinguished by a DC/DC converter circuit (), an energy storage device () and a changeover switch (), which are designed and arranged so that the energy storage device () is changeable by the DC/DC converter circuit () and the changeover switch () enables an electrical connection between the voltage-sensitive consumer () and the energy storage device () in such a way that the energy storage device () in case of need supplies a stabilization voltage (U) at the consumer ().

Voltage stabilization apparatus

A system for monitoring a plurality of capacitor cells connected in series in a capacitor module which are used as electrical energy stores in an energy storage device and which can be charged in same by a charge current flowing through all the capacitor cells or discharged by a discharge current. The system includes a measuring unit which can determine the voltages applied to the individual capacitor cells by measuring voltages, an evaluation unit which sets a nominal voltage for the capacitor cells, and at least one discharge branch connectable to each capacitor cell and controllable by a discharge control unit which discharges a respective capacitor cell onto said discharge branch depending upon the set nominal voltage and the applied voltage.
