  • Patent number: 10717409
    Abstract: The method for a two-stage authorization of a charging operation includes a first stage and a second stage. In the first stage, a control device allocated to the charging station receives a terminal-side proof of authorization transmitted from a mobile terminal device. The first personal authorization of the charging station user is verified on the basis of the terminal-side proof of authorization, without any action of the charging station user being required. With the given first authorization, the charging cable is released. In the second stage, the vehicle-side proof of authorization is received and verified after the vehicle has been connected to the charging cable, whereupon in response to verification of the vehicle-side proof of authorization, a second authorization is carried out, due to which the charging operation is approved.
