The invention relates to a method for access control and session control of electrical producers and/or consumers in generally accessible or commonly accessible energy transfer units, wherein the producer or the consumer is authenticated and authorized at the energy transfer unit, and producer- or consumer-specific data are forwarded by the energy transfer unit to an energy provider after authentication and authorization of the producer or the consumer. Then a session token is generated for the control of the energy transfer by the energy provider, and the session token is forwarded to the energy transfer unit and the producer or the consumer, wherein the session token has a temporary validity. Electrical energy is transferred between the energy transfer unit and the producer or the consumer, wherein in a defined time interval during the energy transfer process the session token is sent at least once by the energy transfer unit to the producer or the consumer and from the producer or the consumer to the energy transfer unit. The method enables in particular simple and retrofittable control of access to freely accessible sockets and public charging stations, which can be used by electric vehicles in the future. In addition, the method enables simple and retrofittable access control of decentralized (private and commercial) energy producers on smart grid networks. For example, electric vehicles can also feed in battery power not required during downtimes (vehicle-to-grid (V2G) systems). |
