Patent ID: 11072244

Abstract:
A method controls the 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 obtain power for charging a vehicle energy store from the power supply system. A central control system can communicate with the respective vehicles and with a server of the power supply system operator and a number of electrical units via communication signals, wherein the number of electrical units each have a higher response time for an electrical power adjustment in response to communication signals from the central control system and/or a higher time synchronicity with respect to a clock of the central control system in comparison with the vehicles. In response to a received reduction command from the server, the control system transmits one or more first commands which suspend the charging of vehicle energy stores to vehicles in the group, wherein the reduction command stipulates a power amount by which the power consumption of the group of vehicles in the power supply system should be reduced. The control system also determines, at predefined intervals of time, a power value which is composed of the reduction in the total power consumption of the vehicle energy stores and the number of electrical units plus the increase in the total power output of the vehicle energy stores and the number of electrical units. In this case, the control system regulates the power value to the power amount according to the reduction command using one or more second commands which are transmitted to electrical units by the control system and change the power consumption and/or power output of electrical units.
