The invention relates to the field of charging piles, and discloses a multistage load balancing method based on an intelligent gateway and a charging pile system. The method is applied to a charging pile system comprising a main line and a plurality of charging lines, and comprises the following steps: setting a main intelligent gateway at a first preset position of the main line; the main intelligent gateway obtains a main load balancing strategy from the charging pile system, and performs first-stage load balancing control on a plurality of charging lines according to the main load balancing strategy; a slave intelligent gateway is arranged at a second preset position of each charging line, and a plurality of charging piles are installed on each charging line; the slave intelligent gateway obtains a slave load balancing strategy from the charging pile system; and the slave intelligent gateway on each charging line performs second-stage load balancing control on the plurality of charging piles of the charging line according to a slave load balancing strategy. Therefore, the charging requests are dispersed to multiple levels, the load pressure of the main intelligent gateway and the charging pile is reduced, the charging power of the charging pile system is balanced, and the overall performance is improved.

    本发明涉及充电桩领域,公开一种基于智能网关的多级负载均衡方法及充电桩系统。该方法应用于包括主线路和若干充电线路的充电桩系统中,包括:在主线路的第一预设位置处设置主智能网关;该主智能网关从充电桩系统中获取主负载均衡策略,根据主负载均衡策略对若干充电线路进行第一级负载均衡控制;在每条充电线路的第二预设位置设置一个从智能网关,每条充电线路安装若干个充电桩;该从智能网关从充电桩系统中获取从负载均衡策略;每条充电线路上的从智能网关根据从负载均衡策略对本条充电线路的若干个充电桩进行第二级负载均衡控制。从而将充电请求分散到多个层级上,减轻主智能网关和充电桩的负载压力,均衡充电桩系统的充电功率,提高整体性能。
