A multi-parking-space alternating current charging centralized control system comprises a main machine and a plurality of auxiliary machines, and the main machine supplies power to the auxiliary machines and controls charging of the auxiliary machines. The main machine is powered by a three-phase 380VAC alternating current, three paths of single-phase alternating current power supplies are uniformly distributed to supply power to the auxiliary machine in the system, and the main machine and the auxiliary machine are respectively provided with two charging interface outputs meeting national standard requirements. The main machine is provided with a three-phase power supply cable input, a power line bank and a wireless network terminal; the input of the three-phase power supply cable is connected with a power distribution system to obtain power supply; the power line bank is used for distributing an input three-phase alternating-current power supply into three paths of single-phase alternating-current power supplies and supplying power to the auxiliary machine through the auxiliary machine cable; the main machine manages all the charging interfaces through a background connected with the wireless network terminal. The auxiliary machine shares the three-phase power supply cable of the main machine, and construction cost is saved. The two charging interfaces of the main machine and the auxiliary machine can be mutually coordinated and automatically switched in turns, and the utilization rate of electric power resources is high.

    多车位交流充电集中控制系统,包括一台主机和多台副机,多台副机均由主机供电和控制充电;主机采用三相380VAC交流供电,均匀分配为3路单相交流电源给系统内的副机供电,主机和副机均设有两个符合国标要求的充电接口输出。主机设有三相供电电缆线输入、电力接线排、无线网络终端;三相供电电缆线输入连接配电系统取得电力供应;电力接线排用于把输入的三相交流电源分配为3路单相交流电源,并通过副机电缆线给副机供电;主机通过无线网络终端连接的后台管理全部充电接口。副机共用主机的三相供电电缆,节省施工费用。主机和副机的两个充电接口可以相互协调,自动轮流切换,电力资源的利用率高。
