Abstract:
1. Charging station for electric vehicles, comprising: a network frequency measuring device, arranged to acquire a network frequency and to detect a deviation in the network frequency from a reference frequency; a load regulating device in operational connection with the network frequency measuring device such that, upon a deviation from the reference frequency being detected in the network frequency, the load regulating device regulates the electrical power emitted to an electric vehicle by the charging station; wherein the load regulating device communicates a reduced charging power to the electric vehicle to reduce the electrical power emitted; and wherein the load regulating device reduces the electrical power emitted by the charging station along a reduction characteristic curve, depending on at least one of the deviation amount detected by the network frequency measuring device, the duration of the deviation, and/or the frequency gradient.
