1. A method for planning an electrical power exchange between a charging infrastructure and an electricity supply grid,
wherein:
the charging infrastructure includes a plurality of charging terminals operable to be connected to a plurality of electric vehicles, respectively, and charge the plurality of electric vehicles such that the plurality of electric vehicles exchange the electrical power with the electricity supply grid via the plurality of charging terminals,
each electric vehicle of the plurality of electric vehicles has a battery of a plurality of batteries, the battery having an individual state of charge of a plurality of individual states of change that is variable, and the battery is operative to draw or output the electrical power, and
the plurality of batteries connected to the charging infrastructure form an overall battery of the charging infrastructure, and the overall battery is characterized by a total storage capacity and a total state of charge, wherein the total storage capacity is variable, and the total state of charge is variable, and
wherein the method comprises:
determining a plurality of arrival time predictions of the plurality of electric vehicles at the plurality of charging terminals; and
determining a total state of charge prediction for the total state of charge for a prediction period depending on the plurality of the arrival time predictions, wherein the total state of charge prediction is a time profile of the total state of charge, wherein determining the total state of charge prediction depending on the plurality of the arrival time predictions includes determining the total state of charge prediction depending on timetables of the plurality of electric vehicles, wherein the timetables are defined by predetermined arrival times and departure times of the plurality of electric vehicles.
