The invention discloses a charging control method, system and device for an electric vehicle charging station. The method comprises the following steps: obtaining the historical daily load of a transformer and the historical daily load of a charging station; performing prediction according to the historical daily load of the transformer and the historical daily load of the charging station to obtain the predicted daily load of the transformer and the predicted daily load of the charging station; substituting the predicted daily load of the transformer and the predicted daily load of the charging station into a preset formula to obtain the planned daily load of a charging pile, and controlling the electric power of the charging pile according to the planned daily load; and judging whether the real-time total load of the transformer is larger than or equal to a first threshold value or not, if yes, reducing the real-time total load of the transformer to a second threshold value, and otherwise, executing the steps again. The technical problem that the charging load and the traditional load peak period of a power grid are superposed due to disordered charging of an existing electric vehicle charging station, so that electricity shortage of local areas is caused, and the load of a power distribution network is unbalanced is solved.

    本申请公开了一种电动汽车充电站充电控制方法、系统和装置,包括:通过获取变压器历史日负荷和充电站历史日负荷,并根据变压器历史日负荷和充电站历史日负荷进行预测,得到变压器预测日负荷和充电站预测日负荷,将变压器预测日负荷和充电站预测日负荷代入预置公式,得到充电桩的计划日负荷,根据计划日负荷控制充电桩的电功率,判断变压器实时总负荷是否大于或等于第一阈值,若是则将变压器实时总负荷降低到第二阈值,否则重新执行上述步骤。解决了现有电动汽车充电站由于无序充电导致充电负荷与电网传统负荷高峰时期叠加,造成局部地区用电紧张、配电网负荷不平衡的技术问题。
