The invention relates to the technical field of electric vehicles, and particularly relates to an integrated three-stage speed reduction electric drive axle. The integrated three-stage speed reductionelectric drive axle comprises an integrated shell, wherein the integrated shell is internally provided with a motor, a three-stage parallel speed reduction gear set and a differential mechanism whichare in transmission connection in sequence, and the integrated shell is of an integrally-formed structure. The integrated three-stage speed reduction electric drive axle further comprises an axle housing, a half shaft and wheels, wherein the two sides of the integrated shell are connected with the axle housing, the half shaft is arranged in the axle housing, one end of the half shaft is connectedwith the output end of the differential mechanism, and the other end of the half shaft is connected with the wheels. The system is high in integration degree, compact in structure and small in occupied space, a transmission shaft is not needed, a battery pack can be arranged in the middle of a vehicle girder, the adaptability to the complete vehicle is good, and the assembling process is simple.
