The invention discloses a parallel charging pile which comprises a monitoring unit (a main control board and a monitoring board) 1, a charger 2, an output contactor 3, an interconnection unit 4 and a charging gun 5. The invention also discloses a parallel charging pile group, which comprises a plurality of parallel charging piles, an interconnection power distribution system and an annular segmentable interconnection bus, wherein the buses and the CAN lines of the plurality of interconnected charging piles are connected through an interconnection unit to form an annular segmentable interconnected bus and CAN line. Under the control of the interconnection power distribution system, the interconnection units of the parallel charging piles can enable adjacent x (x is greater than or equal to 1) parallel charging piles to form a parallel output relation, and various charging powers can be freely combined. Along with the development of electric vehicles, the electric vehicles become more and more diversified in the future, the charging power requirements become more and more diversified, the compatibility of the charging piles can be improved through diversified power charging of the parallel charging piles, and one pile can charge all vehicles in groups.

    本发明公开了一种并联充电桩,包括1监控单元(主控板、监控板)、2充电机、3输出接触器、4互联单元和5充电枪。本发明也公开了一种并联充电桩群,其包括上述多台并联充电桩、互联功率分配系统和环形可分段互联母线;其中所述多台互联充电桩的母线和CAN线通过互联单元连接,形成环形可分段互联母线和CAN线。在互联功率分配系统的控制下,所述并联充电桩的互联单元能够将相邻的x台(x≥1)所述并联充电桩组成并联输出关系,可以自由组合多种充电功率。随着电动汽车的发展,未来电动汽车越来越多元化,充电功率需求也是越来越多样化,并联充电桩的多元化功率充电可以提高充电桩的兼容性,做到一桩群充所有车。
