The invention discloses a driving and charging integrated circuit, an electric vehicle and a control method and a control system thereof, and belongs to the field of electric vehicles. A three-phase two-level motor driving circuit, an auxiliary bridge arm unit and a multiplexer switch are included. The three-phase two-level motor driving circuit and the positive electrode of the auxiliary bridge arm unit are short-circuited together to form a first interface positive electrode, the negative electrode is short-circuited together to form a first interface negative electrode, and the first interface is used for connecting a vehicle-mounted battery; alternating current interfaces of three half-bridge units in the three-phase two-level motor driving circuit are led out to form a second interface which is connected with three sorting lines of the multiplexer switch respectively, and the second interface is used for being electrically connected with a three-phase stator winding of the driving motor; and a multiplexer switch bus serves as one end of a third interface, the alternating current interface of the auxiliary bridge arm unit is led out to serve as the other end of the third interface, and the third interface is electrically connected with an alternating current power grid. According to the invention, only one auxiliary bridge arm and the multiplexer switch are added, the permanent magnet synchronous motor does not need to be changed, and a grid connection function is realized.
