The invention belongs to the technical field of electric vehicles, and particularly relates to a dual-motor power system and an electric vehicle. The dual-motor power system comprises a first motor, a second motor, a differential mechanism, a one-way clutch and a transmission, wherein the transmission comprises a first output shaft, a second output shaft, an intermediate shaft and a controllable torque transmission device; a driving shaft of the first motor is connected with the first output shaft, and a driving shaft of the second motor is connected with the second output shaft; the controllable torque transmission device is connected with the first output shaft; and the one-way clutch is installed on the intermediate shaft, and the transmission is connected with automobile wheels through the differential mechanism. According to the dual-motor power system, the reverse dragging resistance during normal running of the vehicle is reduced while the power performance is enhanced, and then the economical efficiency is improved. Meanwhile, the integration degree of the dual-motor power system is high, and the installation space is saved.
