Abstract
A circuit arrangement for controlling at least one charging contactor of a charging system of an electrically operated vehicle includes at least one differential amplifier having two inputs and one output. The first input is electrically coupled to a first pole of an input voltage supply of the charging system for supplying an input voltage and the second input is electrically coupled to a second pole of the input voltage supply. The arrangement also includes a comparator having two inputs and one output. The first input is electrically coupled to the output of the differential amplifier and the output is electrically coupled to a control cable of the at least one charging contactor of the charging system.
