A method for providing electric exchange power for multiple electric vehicles of a fleet of electric vehicles, for feeding into an electricity supply grid or drawing from the electricity supply grid by way of a charging infrastructure of the fleet, wherein a positive exchange power denotes an electric power drawn from the electricity supply grid by the fleet and a negative exchange power denotes an electric power fed into the electricity supply grid by the fleet, and wherein each electric vehicle has an electrical storage unit having a changeable state of charge, and the sum of the changeable states of charge of the electric vehicles of the fleet, and possibly further changeable states of charge of further storage units, forms a changeable sum state of charge, wherein a state of charge range is determined for a provision period, this state of charge range spanning an operating range that should contain the sum state of charge, wherein the state of charge range is characterized by a time-dependent upper limit that specifies maximum values that should not be exceeded for the sum state of charge in a time-dependent manner, and by a time-dependent lower limit that specifies minimum values that should not be dropped below for the sum state of charge in a time-dependent manner, and wherein the state of charge range is determined on the basis of the states of charge of the electric vehicles, and wherein the electric exchange power is controlled in the provision period such that the sum state of charge does not leave the state of charge range.
