Abstract

A method controls electrical charging of a group of vehicles which are electrically connected to a power supply system of a power supply system operator, wherein the respective vehicles draw power from the power supply system for charging a vehicle-side energy store for driving the respective vehicle. A central control system can communicate with the respective vehicles of the group and also with a server of the power supply system operator, wherein the central control system, in response to a received reduction command which originates from the server of the power supply system operator, carries out a charging power reduction control operation for the group of vehicles using charging power measurement values of the respective vehicles and in the process reduces the charging power of at least some of the vehicle-side energy stores in order to reduce the total charging power of the groups of vehicles at least by a power value which is specified by the reduction command. The charging power measurement value of a respective vehicle is measured during charging of the vehicle and provided to the central control system, wherein one or more maximum power values for charging the respective…
