Abstract
A device for controlling the exchange of energy between an electrical power network and a load includes a stationary charging station for establishing an energy connection between the electrical power network and a supply point. The charging station has an LS controller for sending and receiving control signals via a signal transmission path, and includes a SIM station installed on the load side having a SIM controller. The SIM controller sends a SIM identifier of the SIM station to the LS controller via a signal transmission path at time intervals, wherein the LS controller adds an amount of energy exchanged between the electrical power network and the load to an energy amount counter associated with the SIM identifier. The amount of energy exchanged between the electrical power network and the load via the energy connection in a time interval is below a specified measurement resolution of the energy amount counter.
