The invention provides an electric vehicle soft queuing charging system and a control method thereof. The electric vehicle soft queuing charging system comprises a master control cabinet, a power bus and a plurality of intelligent charging piles. The power bus is electrically connected with the intelligent charging pileS; the master control cabinet comprises a master controller, a grid-connected circuit breaker and a first information acquisition module, one end of the grid-connected circuit breaker is electrically connected with a feeder line in a power grid, and the other end of the grid-connected circuit breaker is electrically connected with THE power bus; the first information acquisition module is used for acquiring electric quantity information flowing from THE power grid to a power bus; the master controller is electrically connected with the intelligent charging pileS, the control signal end of the grid-connected circuit breaker and the output end of the first information acquisition module. The master controller is used for controlling the real-time output power of each intelligent charging pile, and the sum of the real-time output power of the intelligent charging piles is smaller than or equal to the maximum transmission power of the feeder lines in the control process. On the premise of ensuring that the feeder line is not overloaded, the number of the intelligent charging piles is increased, and the win-win situation of an electric vehicle user and a power grid is achieved.

    本发明提供了一种电动汽车软排队充电系统及其控制方法,电动汽车软排队充电系统包括:总控制柜、功率母线及多个智能充电桩;功率母线与智能充电桩电连接;总控制柜包括总控制器、并网断路器及第一信息采集模块,并网断路器的一端与电网中一馈线电连接,另一端与功率母线电连接;第一信息采集模块用于采集电网流向功率母线的电量信息;总控制器分别与智能充电桩、并网断路器的控制信号端及第一信息采集模块的输出端电连接;总控制器用于控制每个智能充电桩的实时输出功率,在控制过程中各智能充电桩的实时输出功率的总和小于或等于馈线的最大传输功率。本发明能在确保馈线线路不过载的前提下,增加智能充电桩数量,实现电动汽车用户和电网双赢。
