Provided is a charging station for electric vehicles. The charging station includes a charge control circuit designed to control a charging process of an electric vehicle at the charging station, a communication module having a charge control interface designed for communication with the charge control circuit, and an operator interface designed for communication with a control centre external to the charging station. A first protocol is implemented in the operator interface for communication with the control centre. Improved interoperability is ensured by providing an interface device arranged at the operator interface in the charging station. This interface device communicates with the operator interface by means of the first protocol and with the external control centre by means of a second protocol which is different from the first protocol.
