The invention discloses an electric vehicle ordered charging optimization method, and relates to the technical field of vehicle ordered charging, and the method comprises the steps: analyzing the optimal output voltage and the optimal output current of a DC charging pile in different power modes; analyzing the fastest full charging time of the electric vehicle, and performing priority charging or non-priority charging marking on the electric vehicle; analyzing the available charging load of the electric vehicle in each time period, the maximum charging load and the minimum charging load of the electric vehicle which is charged preferentially in each time period, and the load mean value of the electric vehicle which is not charged preferentially in each time period; and determining the charging sequence and the initial charging power of each electric vehicle, and outputting the charging sequence and the actual charging power of each electric vehicle in combination with the optimal output voltage and the optimal output current of the direct current charging pile in each power mode. The load fluctuation rate of the direct-current charging pile and the power loss of the direct-current charging pile line can be reduced, the stability of the direct-current charging pile is improved, and the service life of the direct-current charging pile is prolonged.

    本发明公开了一种电动汽车有序充电优化方法,涉及汽车有序充电技术领域,包括分析直流充电桩不同功率模式下的最优输出电压和最优输出电流;分析电动汽车最快充满时间,对电动汽车进行优先充电或非优先充电标记;分析电动汽车在每个时间段的可用充电负荷、每个时间段内优先充电电动汽车的最大充电负荷和最小充电负荷及每个时间段内非优先充电电动汽车的负荷均值;确定每个电动汽车的充电顺序和初设充电功率,并结合直流充电桩每个功率模式下的最优输出电压和最优输出电流,输出每个电动汽车的充电顺序和实际充电功率。可以降低直流充电桩负荷波动率和减少充直流充电桩线路电力损耗,提高直流充电桩稳定性,延长直流充电桩使用寿命。
