The invention discloses a charging pile metering system in the field of power metering, which aims to solve the technical problem that the charging piles in the prior art are numerous and discretely distributed, and the construction and maintenance cost of using 3G/4G, GPRS, fiber optic cable communication is high. The charging pile metering system includes a terminal node; the terminal node collects data of the charging pile, and uploads the data to a coordinator node through a wireless communication network, the coordinator node is connected with an upper computer, and the received data aretransmitted to the upper computer; and the upper computer sends an instruction to the terminal node through the coordinator node, and the terminal node executes the instruction of the upper computer.According to the charging pile metering system provided in the invention, the numerous charging piles in a parking lot can be metered and controlled at the same time, the cumbersome wiring can be saved, the communication cost is reduced, the change is easy, the expansibility is strong, the maintenance is convenient, and the application range is wider.
