The invention relates to a distributed electric drive system and an electric vehicle. The bottleneck problem that the distributed electric drive system is arranged on a new energy vehicle chassis in the X direction and the Y direction is solved. The distributed electric drive system comprises a dual-motor assembly, a first transmission group and a second transmission group which are integrated together, the first transmission set and the second transmission set are arranged on the two sides of the double-motor assembly in the width direction of the vehicle. The dual-motor assembly comprises an outer rotor motor and an inner rotor motor, and the inner rotor motor is radially nested in the outer rotor motor; the inner rotor motor transmits power to a wheel on one side of the vehicle through the first transmission set, and the outer rotor motor transmits power to a wheel on the other side of the vehicle through the second transmission set. The outer rotor motor transmits power to wheels on the other side of the vehicle through the second transmission set. An input shaft of the first transmission group multiplexes an output shaft of the inner rotor motor; and the input shaft of the second transmission group multiplexes the output shaft of the outer rotor motor.
