DEVICE AND METHOD FOR EXCHANGING ENERGY IN A CONTROLLED MANNER BETWEEN AN ELECTRICAL POWER NETWORK AND A LOAD

摘要

The invention relates to a device and method for exchanging energy in a controlled manner between an electrical power network and a load. In order to enable a flexible and at the same time secure charging process of rechargeable batteries, a device for exchanging energy in a controlled manner between an electrical power network and a load is provided, comprising a stationary charging station for establishing an energy connection between the electrical power network and a supply point, wherein the charging station has an LS controller for sending and receiving control signals by means of a signal transmission path, and comprising a SIM station installed on the load side for establishing an energy connection between the load and said supply point, wherein the SIM station has a SIM controller for sending and receiving control signal by means of the signal transmission path, wherein the SIM controller sends a SIM identifier associated with the SIM station to the LS controller by means of the signal transmission path at time intervals, wherein the LS controller adds an amount of energy exchanged or to be exchanged between the electrical power network and the load by means of the energy connection to an energy amount counter associated with the SIM identifier when a SIM identifier is received, and wherein the time intervals are dimensioned in such a way that the amount of energy exchanged or to be exchanged between the electrical power network and the load by means of the energy connection in a time interval is below a specified measurement resolution of the energy amount counter.
