The invention provides a power distribution method and device for a charging pile group. The method comprises the steps that whether the total number of charging piles which transmit a control request in the charging pile group is greater than a preset threshold value or not is judged; if yes, whether the charging piles sending the control request meet control conditions or not is sequentially judged according to the state information, recorded in an available capacity block chain, of the charging piles in the sequence of sending the control request; if yes, the charging pile meeting the control condition is selected as a main control charging pile, and other charging piles are set as controlled charging piles; and a corresponding power distribution control strategy is executed through the main control charging pile. Therefore, the charging pile meeting the control condition is selected as the main control charging pile to realize power distribution, the situation of system breakdown caused by failure of the main control unit can be effectively avoided, and the reliability of the system is greatly improved.

    本发明提供了一种充电桩群的功率分配方法和装置,其中,该方法包括:判断充电桩群内发送控制请求的充电桩的总数是否大于预设阈值;如果是,则根据可用容量区块链中记录的充电桩的状态信息按照发送控制请求的先后顺序依次判断发送控制请求的充电桩是否满足控制条件;如果是,则将满足控制条件的充电桩选取为主控制充电桩,并将其他充电桩设置为被控制充电桩;通过主控制充电桩执行相应的功率分配控制策略。由此,选取满足控制条件的充电桩作为主控制充电桩以实现功率分配,能够有效地避免因主控单元失效而导致系统瘫痪的情况,大大提高了系统的可靠性。
