The invention provides a multipath charging control switch device sharing an AC power supply. The multipath charging control switch device is formed by correspondingly connecting four single-phase intelligent electric energy meters, a 4G router, an intelligent multipath switch and four leakage protectors. The capacity of the input power supply is greater than 7kW, the input power supply is connected to the input terminals of the electric energy meters and provides working power for the router and the intelligent multi-way switch, the outputs of the four electric energy meters are respectively connected with the corresponding power supply input terminals of the intelligent multi-way switch, the RS485 terminals of the electric energy meters are connected in parallel with the RS485 terminals of the intelligent multi-way switch, and the RS485 terminals of the intelligent multi-way switch are connected with the router. Each path of power supply output of the intelligent multi-path switch and the grounding PE are connected with the input of the leakage protector, and the output of each leakage protector is connected with the corresponding charging pile.
