The invention belongs to the technical field of charging piles, and discloses a method and system capable of adjusting the output power of a charging pile in real time. Comprising the steps of obtaining pre-stage power distribution capacity and a safety power value of a charging pile; in the charging process, the charging pile collects the power value of the electric meter in real time; the charging pile adjusts output power according to the electric meter power value and the pre-stage power distribution capacity and the safety power value of the charging pile, the actual available power supply power is calculated through the pre-stage power distribution capacity and the safety power value of the charging pile, and the actual available power supply power is compared with the electric meter power value; according to the comparison result, the output power of the charging pile is increased, the output power of the charging pile is reduced or the current power is maintained, under the condition of safe electricity utilization, the method is economical and practical, and the technical problem that in the prior art, when the actual electricity utilization power of the charging pile exceeds the preceding-stage power distribution capacity, current overload in a power supply line is caused is solved.

    本发明属于充电桩技术领域,公开一种可实时调节充电桩输出功率方法及系统;包括获取充电桩前级配电容量和安全功率值;充电过程中,充电桩实时采集电表功率值;充电桩根据电表功率值以及充电桩前级配电容量与安全功率值调节输出功率,通过充电桩前级配电容量与安全功率值计算实际可用供电功率,将实际可用供电功率与电表功率值进行对比,根据对比结果增加充电桩输出功率、减少充电桩输出功率或维持当前功率,在安全用电的情况下,又经济实惠,解决现有技术中充电桩的实际用电功率超过前级前级配电容量时,导致供电线路中的电流过载的技术问题。
