The invention discloses a double-electric-drive-axle system and a vehicle. The double-electric-drive-axle system comprises a first drive motor, a second drive motor, a differential mechanism, a first gear reduction unit, a second gear reduction unit and a motor controller. The first gear reduction unit is composed of a first gear and a second gear, the first gear is coaxial with the first driving motor and meshed with the second gear, and a rotating shaft of the second gear is connected with the differential mechanism; the second gear reduction unit is composed of a third gear, a fourth gear, a fifth gear and a sixth gear, the sixth gear is coaxial with the second driving motor, the sixth gear is meshed with the fifth gear, the fifth gear is coaxial with the fourth gear, the fourth gear is meshed with the third gear, and the third gear is meshed with the second gear; the transmission ratio of the first gear reduction unit is smaller than that of the second gear reduction unit; and the first driving motor and the second driving motor are electrically connected with the motor controller. The multi-working-condition adaptive capacity and the driving efficiency of the system are improved.
