Abstract

A method for operating a system for supplying a vehicle with electrical energy, wherein the system has a charging station, an energy management unit and a translation unit. The translation unit has a first communications interface for communicating with the energy management unit, and a second communications interface which can be coupled for communication with the vehicle. In the event that the vehicle is coupled with the second communications interface, the system provides a minimum power parameter representative of a minimum electrical power that is to be supplied to the vehicle. A first evaluation matrix is provided to the translation unit via the first communications interface, which includes a first evaluation parameter for each future first time period and for each first power stage of electrical power to be supplied via the system. The evaluation parameter is representative of an output associated with a supply of the respective electrical power for each first time period. Depending on the minimum power parameter and the first evaluation matrix, a second evaluation matrix is determined by the translation unit, which is representative of an estimation of the output. The seco…
