The invention discloses a charging pile automatic power distribution method based on an annular connection method. The method comprises the following steps: acquiring a charging gun serial number; searching other modules which can be associated for the charging gun according to the online conditions of the modules on the two sides of the direct connection module of the charging gun; associating the other searched modules with the charging gun; and distributing the output power of the module associated with the charging gun to the charging gun. According to the method, automatic power distribution is carried out according to real-time searching of the number of online modules, even if part of modules are damaged and offline in the later period, use of most guns is not affected, full-power output of any single gun, average power output of any double guns and average power distribution of more than three guns as much as possible can be achieved, and if equal distribution cannot be achieved due to limitation of an annular connection method, the gun which is started firstly obtains relatively high power, so that efficient distribution of power is realized.

    本发明公开一种基于环形接法的充电桩自动功率分配方法,包括如下步骤:获取充电枪序号;根据所述充电枪的直连模块两侧的模块在线情况,为所述充电枪查找可以关联的其他模块;将查找到的所述其他模块与所述充电枪关联;将与所述充电枪关联的模块的输出功率分配给所述充电枪。本发明方法根据在线模块数量实时查找进行功率自动分配,即使后期部分模块损坏掉线,也不影响大部分枪的使用,可以实现任意单枪满功率输出、任意双枪平均功率输出、三枪以上尽可能平均分配功率,若因环形接法限制不能均分,则先启动的枪获得较大功率,实现了功率的高效分配。
