The invention relates to the technical field of electric vehicle charging management, in particular to an electric vehicle charging balance control method and system. The method comprises the following steps: step S10, periodically executing according to an optimization period; step S30, performing zero clearing on power supply pre-distribution power of each phase of a power grid in a region; s40, the charging power Pj of all the charging piles in the area is ranked from large to small according to absolute values; and S50, traversing all the charging piles from the charging pile with the maximum charging power, and switching the charging pile to a corresponding power grid phase according to the positive and negative of the charging power Pj. According to the electric vehicle charging balance control method, the charging phase of each charging pile can be dynamically controlled in real time, the load of the power grid in the area is balanced, and the method is simple and easy to use.

    本发明涉及电动车充电管理技术领域,尤其涉及一种电动车充电平衡控制方法和系统。所述方法包括:步骤S10,根据优化周期周期性执行:步骤S30、将区域内电网各相位的供电预分配功率清零;步骤S40、将区域内所有充电桩的充电功率Pj按绝对值进行从到大到小排序;步骤S50、从最大充电功率的充电桩开始遍历所有充电桩,根据充电功率Pj的正负,将该充电桩切换到相应的电网相位。本发明电动车充电平衡控制方法,可实时动态控制每个充电桩的充电相位,使所在区域的电网负载平衡,简单易用。
