The invention belongs to the technical field of charging equipment, and discloses a regular polygon preemptive electric vehicle on-demand power distribution charging circuit, method and charging pile. Every two charging modules are interconnected according to a regular polygon structure, the charging modules are connected with charging equipment through power cables, and a contactor group is arranged between every two interconnected charging modules. When a plurality of electric vehicles are charged at the same time, under the condition that all charging modules can be mutually borrowed, the use of the contactor group is reduced, the circuit design cost and the structural complexity are reduced, and the space requirement of a box body is saved. According to the invention, the power is distributed as required, power allocation is carried out according to the real-time power of the electric vehicle, the charging utilization rate of the charging modules is greatly improved, and the economic benefit of charging is remarkably improved. According to the preemptive design of the charging modules, each charging device can be distributed to the lowest group of charging modules, so that the overall use efficiency of the charging equipment is remarkably improved.
本发明属于充电设备技术领域,公开了一种正多边形抢占式电动汽车按需分配功率充电电路、方法、充电桩,充电模块按照正多边形结构两两互联,充电模块通过电力线缆与充电设备连接,充电模块两两互联之间设置有接触器组。本发明对多辆电动汽车同时充电时,在能够实现充电模块全部可以互相借调的情况下,减少了接触器组的使用,降低电路设计成本和结构复杂性,节省了箱体空间要求。本发明功率按需分配,是根据电动汽车的实时功率进行功率调配,极大地提高了充电模块的充电利用率,使充电的经济效益显著提升。本发明充电模块抢占式设计,可以使每把充电设备都能够分配到最低一组的充电模块,使充电设备整体使用效率显著提升。
