System and method for authenticating a charging procedure for an electric vehicle at a charging station

A system for authenticating a charging procedure for an electric vehicle at a charging station, comprising:

• a charging station having a charging device and an energy source, a user interface, a storage unit, a processor, and a communication module,
• wherein the charging station is connectable via the communication module by a mobile radio link to a network and to a back-end server,
• wherein a mobile device is connectable to the network, the back-end server, and the communication module of the charging station,
• wherein a mobile application is installed on the mobile device,
• wherein the communication module is configured to check whether a connection exists to the network and to the back-end server, and, if no connection exists to the network and to the back-end server, to communicate that no connection exists to the processor, and
• wherein the processor is configured to generate a message on a display device of the user interface indicating that an input of an authentication code is required in order to enable the charging procedure, to compare an entered authentication code with an authentication code stored in a storage unit of the charging station, and to authorize and enable the charging procedure if the entered and stored authentication codes match one another, or to refuse the charging procedure if the authentication codes do not match one another.
