The invention discloses a topology circuit of an isolated single-phase integrated vehicle-mounted charging system for an electric vehicle and a control method of the topology circuit. The topology circuit comprises an open-winding permanent magnet synchronous motor, a dual three-phase inverter, a power battery pack, a bus capacitor, a high-frequency transformer, a winding change-over switch K1, a winding change-over switch K2 and a bus change-over switch G1, through switching of the winding change-over switch K1, the winding change-over switch K2 and the bus change-over switch G1, the system works in a driving mode or a charging mode, and the system is controlled in combination with a driving control method and a charging control method. According to the invention, electrical isolation of the integrated vehicle-mounted charging system is realized without adding extra power devices and industrial frequency transformers, and the reliability and safety of charging are improved.
