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, wherein a positive exchange power denotes an electric power drawn from the electricity supply grid and a negative exchange power denotes an electric power fed into the electricity supply grid, 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 and the changeable states of charge of further storage units form a changeable sum state of charge, wherein a state of charge range is determined for a provision period, wherein the state of charge range is characterized by a time-dependent upper limit and by a time-dependent lower limit, 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.

    本发明涉及一种用于借助于充电基础设施为由电动车构成的车队中的多个电动车提供电交换功率以从所述供电网中提取或者向供电网中馈入电交换功率的方法,正交换功率表示从供电网中提取的电功率,负交换功率表示馈入到供电网中的电功率,每个电动车都具有带有可变的荷电状态的电储存器,可变的荷电状态与其它储存器的其它可变的荷电状态的总和形成可变的总荷电状态,在提供时间段内确定荷电状态范围,荷电状态范围的特征在于时间相关的上限和时间相关的下限,根据电动车的荷电状态来确定所述荷电状态范围,在所述提供时间段中控制电交换功率,使得总荷电状态不偏离所述荷电状态范围。
