Claims

1. An adapter for electric charging of an electric vehicle using a vehicle-side plug-in charging system at a charging station that uses a station-side plug-in charging system that is different from the vehicle-side plug-in charging system, the adapter comprising:

a station-side plug-in charging system charging socket;

a vehicle-side plug-in charging system charging plug;

a data interface using a data communications technology of the vehicle-side plug-in charging system, the data communications technology of the vehicle-side plug-in charging system being based on a power-line transmission;

a data interface using a data communications technology of the station-side plug-in charging system, the data communications technology of the station-side plug-in charging system being based on a CAN bus transmission; and

a processing unit which converts data for the data communications technology of the vehicle-side plug-in charging system into data for the data communications technology of the station-side plug-in charging system, and/or conversely, wherein the processing unit converts data flow during a fast-charging process by converting data according to a CAN bus protocol into data according to a pulse-width-modulation protocol, thereby enabling the fast-charging process by performing a handshake between the charging station or adapter and the battery management of the electric vehicle only on a basis of the pulse-width modulation, wherein, in response to the handshaking indicating that the electric vehicle is suitable for fast charging, the charging process on the vehicle side is switched over to a power-line communication.
