Abstract

In connection with an electric charging process of vehicles electrically connected to a power supply system operated by a power supply system operator, one or more parameters to be adhered to for a charging operation of the vehicles are defined and a user of a vehicle can alter at least one of the parameters via a user interface. A central control system is configured to communicate with the vehicles and with a server of the power supply system operator. A method includes performing a power reduction operation in accordance with a reduction scheme in response to a received reduction command. In the event that, after receiving the reduction command and prior to or during the power reduction operation, the user alters at least one of the one or more parameters such that the charging operation of the energy storage device of the respective vehicle is altered, the method further includes checking, by the central control system, whether a preset criterion has been met. In the event that the preset criterion has been met, the method further includes beginning or continuing the power reduction operation in accordance with the reduction scheme for the respective vehicle while adhering to t…
