1. A method for authenticating a charging procedure for an electric vehicle at a charging station, comprising:
checking, by a communication module, whether a connection exists to a network and to a back-end server;
establishing, by the communication module, that no connection exists to the network and to the back-end server, and communicating that no connection exists to a processor;
generating a message on a display device of a user interface indicating that an input of an authentication code is required to enable the charging procedure;
comparing an entered authentication code with an authentication code stored in a storage unit of the charging station, wherein a detection of a transponder on a charging device of the charging station is required in addition to the input of the authentication code; and
authorizing and enabling the charging procedure if the entered and stored authentication codes match one another, or refusing the charging procedure if the authentication codes do not match one another.
