CHARGING STATION FOR CHARGING ELECTRIC VEHICLES, COMPRISING A CONTROL DEVICE FOR DETERMINING AN EQUIVALENT STORAGE CAPACITY OF A VIRTUAL PRECHARGE STORE, AND ASSOCIATED METHOD

摘要

A charging station for charging electric vehicles, wherein the charging station comprises a network connection point, via which the charging station is connected to an electricity supply network, for the take-up of electric power from said electricity supply network, wherein the network connection point assumes a connection capacity value, up to which a maximum take-up of power from the electricity supply network can be executed by the charging station, at least one charging terminal, for the charging of one electric vehicle respectively, at least one controllable load to the at least one charging terminal, and a control device for controlling the charging station, wherein the control device is designed to determine an equivalent storage capacity of a virtual precharge store, and to control the charging of electric vehicles in accordance with the connection capacity value and the equivalent storage capacity, wherein the equivalent storage capacity describes a value which corresponds to a storage capacity of a virtual electrical precharge store which, for a predefined charging period, can deliver an additional charging capacity, which is dictated by the storage capacity, in order to increase a charging capacity which is restricted by the connection capacity value.
