Patent ID: 10814732

Abstract:
A method controls the electric charging of a group of vehicles. A central control system can communicate with the respective vehicles of the group and with a server of the network operator. In each case a charging time window, a departure time and a setpoint state of charge of the vehicle-side energy store at the departure time are defined in advance for one or more specific vehicles. In addition, a cost value for the charging time window is predefined in accordance with a cost function which specifies a cost level as a function of the charging process according to the charging time window. The central control system transmits a modified charging time window to a respective specific vehicle of at least some of the specific vehicles, after which the charging process is carried out according to the modified charging time window by fulfilling the charging time criterion with an unchanged departure time and setpoint state of charge. The modified charging time window comprises at least one time period which occurs before the start of the non-modified charging time window, wherein the cost value according to the cost function for the modified charging time window is precisely as high as or is lower than the cost value for the non-modified charging time window.
