The invention discloses a flexible charging regulation and control method of a charging pile and a charging pile system with a flexible charging regulation and control function. According to the method and system, charging piles are communicated with one another in a self-networking way, the charging power of the charging piles is monitored in real time and controlled automatically, so that the sum of power of the charging piles within an area is lower than the rated power of a transformer, ordered charging and flexible control are realized, and influence of charging for electromobile on the distribution network is reduced. A charging station or the charging pile of a special-purposed transformer is taken as unit, under the condition that charging load demand of the area is satisfied, thearea charging pile of the charging station and special-purposed transformer can adjust the load, the maximal power of the charging piles in the area is balanced and adjusted automatically, the special-purposed transformer in the charging station is prevented from overload, and ordered charging of the eletromobile and safe and economical operation of the distribution network are realized.
