The invention belongs to the field of electric vehicle charging load distribution, and provides an electric vehicle charging load distribution method and system. The electric vehicle charging load distribution method comprises the steps that: a charging process is started, charging modules are dynamically distributed in real time along with the change of charging power requirements according to the principle of first coming first served and minimum charging, and meanwhile the power ratio of all charging muzzles is adjusted so as to achieve power balance distribution; the state of the charging module or the power group in the charging process is obtained in real time, and if the charging module or the power group generates communication interruption or fault, the charging module or the power group is marked to be shut down by adopting a flexible processing mechanism and is split from the charging; and when the continuous accumulated marked shutdown times of the charging module or the power group exceed a preset threshold value, the power group or the charging module is split from the system.

    本发明属于电动汽车充电负荷分配领域,提供了一种电动汽车充电负荷分配方法及系统。其中,电动汽车充电负荷分配方法包括启动充电流程,以先到先得及最小充电为原则,随充电功率需求变化实时动态分配充电模块,同时调整各个充电枪口的功率配比,以实现功率平衡分配;实时获取充电过程中的充电模块或功率组的状态,若充电模块或功率组产生通信中断或故障,则采用柔性处理机制将充电模块或功率组标记关机并从本次充电中解列;当充电模块或功率组连续累计标记关机的次数超过预设阈值时,将该功率组或充电模块从系统中解列。
