The invention relates to a series-parallel connection switching circuit, a multi-power-supply series-parallel connection switching circuit and a vehicle charging pile. The series-parallel switching circuit comprises a first power supply module, a second power supply module, a gating device and a conducting device. The gating device comprises a gating terminal, a first terminal and a second terminal, and the gating device is used for connecting or disconnecting paths between the gating terminal and the first terminal and between the gating terminal and the second terminal; the conducting device comprises a third terminal and a fourth terminal and is used for conducting or disconnecting a path between the third terminal and the fourth terminal; the cathode end of the first power supply module is connected with the gating terminal, and the anode end of the second power supply module is connected with the first terminal and the fourth terminal; the positive electrode end of the first power supply module is connected with the third terminal to serve as the output positive electrode end of the series-parallel switching circuit; the negative electrode end of the second power supply module is connected with the second terminal to serve as the output negative electrode end of the series-parallel switching circuit. By adjusting the circuit architecture, the overall cost of the series-parallel switching circuit is reduced.
