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, the producer or the consumer being authenticated and authorized at the energy transfer unit, and producer- or consumer-specific data being forwarded by the energy transfer unit to an energy provider after authentication and authorization of the producer or the consumer. A session token is subsequently 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, the session token having time-limited validity. Electrical energy is transferred between the energy transfer unit and the producer or the consumer, in a defined time interval during the energy transfer process the session token being sent at least once from the energy transfer unit to the producer or the consumer and from the producer or the consumer to the energy transfer unit. |
