The invention relates to the technical field of vehicles, and discloses a power system of an electric automobile, a control method and the electric automobile. The power system of the electric automobile comprises a first differential mechanism, a second differential mechanism, a first motor, a second motor and a third motor, wherein a first output end and a second output end of the first differential mechanism and the second differential mechanism are connected with two wheels respectively; an output end of the first motor is in transmission connection with an input end of the first differential mechanism, and a first clutch is arranged between the first motor and the first differential mechanism; an output end of the second motor is in transmission connection with an input end of the second differential mechanism; an output end of the third motor is in transmission connection with an input end of the second differential mechanism, and a second clutch is arranged at an output end of the third motor or between an output end of the second motor and an input end of the second differential mechanism. Through the structure, the power system of the electric automobile reduces follow-up loss of the motor, reduces resistance of the automobile, and is beneficial to reducing energy consumption of the automobile and prolonging the endurance mileage of the automobile.
