The invention provides an intelligent load balance control method in the charging process of an electric vehicle, and relates to the technical field of electric vehicle charging management, and the method comprises the steps: reading the charging pile rated power and the charging pile real-time power of a charging pile, calculating the distributable capacity of a charging station according to parameters, and judging whether the charging pile is in an overload state or not; when the charging piles are in the overload state, the real-time power of each charging pile is reduced according to the power proportion of each charging pile, so that the real-time power of the charging piles is reduced to the rated power of the charging piles, and when the charging piles are in the non-overload state and approach the load upper limit, the charging power of the charging piles which are being charged is reduced. In particular, for the charging piles with low load rates, a linear or nonlinear power adjustment strategy can be adopted, for example, the residual power is distributed according to the reciprocal proportion of the load rates of the charging piles, so that the load balance of the charging piles is adjusted, and the stability of a power grid and the charging piles is improved.

    本发明提供了一种电动车辆充电过程的智能负载平衡控制方法,涉及电动车充电管理技术领域,通过读取充电桩的充电桩额定功率和充电桩实时功率,从而根据参数计算充电站的可分配容量,从而判断充电桩是否处于过载状态,当充电桩处于过载状态时,根据各个充电桩的功率占比按比例降低各个充电桩的实时功率,以使充电桩实时功率降低到充电桩额定功率,当充电桩处于未过载状态且接近负载上限时,降低正在充电的充电桩的充电功率,特别是那些负载率较低的充电桩,可以采用线性或非线性的功率调整策略,如按照充电桩负载率的倒数比例分配剩余功率,从而实现对充电桩负载平衡的调节,有利于提高电网以及充电桩的稳定性。
