A method and a control unit for controlling the authorization of charging operations of electrically operated vehicles. A control unit is provided between a main terminal and a plurality of electric coupler sockets, which are connected to the control unit via a power line. A vehicle to be charged is connected to one of the electric coupler sockets, and the total charging current, which is conducted from the main terminal to the electric coupler sockets via the control unit, is measured. Charging-current requests are transmitted to the control unit by each of the vehicles connected to the electric coupler sockets, and the total charging current is compared to the sum of the charging currents reported by the vehicles connected to the charging outlets. The charging outlets are switched off if the total charging current exceeds the sum. The connecting of a vehicle to be charged includes transmitting authorization information from the vehicle to the control unit. The authorization information is compared to a list of authorized vehicles by the control unit, in order to check the authorization of the vehicle. The transmitting of charging-current requests and authorization information is provided by modulating an alternating current signal upon the power line, the alternating current signal representing the authorization request or the charging-current request.
