The invention discloses a hybrid electric system adopting a double-rotor motor. The hybrid electric system comprises the double-rotor motor, a double-motor controller and an engine, wherein the double-rotor motor comprises an inner rotor motor and an outer rotor motor; the inner rotor motor is engaged with a power output shaft or a four-speed gear bank through an inner rotor motor reduction gear bank; the outer rotor motor is connected with the power output shaft through an outer rotor motor reduction gear bank; the double-motor controller is used for independently controlling the inner rotor motor and the outer rotor motor, and is connected with a power battery; an output shaft of the engine is engaged with one of a one-speed gear bank, a two-speed gear bank, a three-speed gear bank and the four-speed gear bank through a clutch, or not engaged with the one-speed gear bank, the two-speed gear bank, the three-speed gear bank and the four-speed gear bank; the one-speed gear bank, the two-speed gear bank and the three-speed gear bank are connected with the power output shaft; the four-speed gear bank is engaged with the power output shaft or the inner rotor motor reduction gear bank. The hybrid electric system adopting the double-rotor motor and an implementation method of the hybrid electric system adopting the double-rotor motor have the characteristics of compact structure, high integration of the system, high efficiency of the vehicle, good fuel economy, smoothness in low-temperature coldstart of the engine and good grade ability at a low speed.
