The invention provides an integrated electric drive axle device and an electric vehicle. The integrated electric drive axle device comprises a reduction gearbox connected with wheels; the first motor is connected with the reduction gearbox; the second motor is connected with the reduction gearbox; the motor controller is simultaneously connected with the first motor and the second motor; the first motor is used for being matched with the second motor to provide driving force needed in a motion mode for the vehicle. The second motor is used for independently providing driving force required in an economic mode for the vehicle or providing the required driving force for the vehicle in cooperation with the first motor; the motor controller is used for controlling the first motor and the second motor to cooperatively apply driving force to wheels. The vehicle operation condition can be optimized in an efficient area of a motor system; the double motors, the motor controller and the differential speed reducer are arranged in a driving system device; the differential reducer integrates a gear, a differential mechanism, a clutch and other mechanisms, the overall integration degree is high, and the current conduction loss is low.
