description The invention relates to a permanent magnet motor technology, and aims to provide an electric vehicle integrated charger based on double three-phase motors and a control method thereof. A dual three-phase open winding permanent magnet motor is adopted, two ends of a stator winding are opened and led out of a stator shell, and the stator winding is respectively connected with an alternating current input power supply and a motor converter through a mode switch; the mode switch reconstructs a winding of the dual three-phase open-winding permanent magnet motor to serve as an electric vehicle charging circuit inductor, so that a motor rotor is kept static during charging; the motor winding is multiplexed as an alternating current side filter inductor during the charging period, and forms a rectifying circuit together with the motor converter. According to the invention, flexible switching between the charging state and the driving state can be realized, and the hardware cost of the electric vehicle is saved; the
