The invention discloses a charging pile flexible power distribution method and a charging pile, and relates to the technical field. The method comprises the following steps: S1, collecting and calculating a total active value Psum of a charging station and active power Pi of each feeder line; s2, the electric vehicle is connected with the charging pile; s3, the charging pile obtains the charging requirement of the electric vehicle and reads the charging time set by a user; s4, the charging pile calculates parameters in the charging process, and the active power Pplan needing to be put into charging of the electric vehicle is obtained; s5, judging whether the active power Pplan of the charging pile is reduced to be lower than the total active power value Psum or not; if yes, returning to the step S4; if not, executing the step S6; and S6, executing a feeder cutting strategy, and cutting the selected feeder. According to the method, the active power of the charging pile is compared with the total active value, part of feeder lines are selected to be cut off through the feeder line cutting strategy, the active power of the charging station can be rapidly controlled, and the comprehensive utilization rate of the charging station is improved.

    本发明公开了一种充电桩柔性功率分配的方法和充电桩,涉及技术领域。本发明包括如下步骤:步骤S1:采集并计算充电站总有功值Psum和各馈线有功功率Pi;步骤S2:电动汽车与充电桩连接;步骤S3:充电桩获取电动汽车的充电需求,并读取用户设定的充电时间;步骤S4:充电桩计算充电过程中的参数,得到需投入给电动汽车充电的有功功率Pplan;步骤S5:判断充电桩有功功率Pplan是否降至总有功值Psum以下;若是,则返回步骤S4;若否,则执行步骤S6;步骤S6:执行馈线切除策略,将选中的馈线切除。本发明通过比对充电桩有功功率和总有功值的大小,利用馈线切除策略来选择部分馈线进行切除,实现快速可控制充电站的有功功率,提高了充电站综合利用率。
