Abstract: A circuit arrangement for operating an energy store of an electric and/or hybrid vehicle includes an analog monitoring circuit. The analog monitoring circuit is designed and arranged to detect a measurement signal that is representative of a current flowing through the energy store, and to generate a predetermined first control signal in a manner dependent on the measurement signal. The circuit arrangement further has a semiconductor switching element which is designed to electrically couple, in a first switching state, the energy store to an electrical energy network, and, in a second switching state, to electrically decouple the energy store from the electrical energy network, The semiconductor switching element includes a control terminal which is coupled by signaling technology to an output of the monitoring circuit. The switching state of the semiconductor switching element is adjustable in a manner dependent on the first control signal.
