The invention discloses an energy recovery device for an electric automobile, relates to the technical field of electric automobile braking, and solves the problems that in the prior art, braking force provided by an electric automobile energy recovery device is low. The device is characterized by comprising: a clutch unit, which is fixedly connected to the driving shaft and the chassis, is connected with a generator and transmits the power of the driving shaft to the generator; the clutch unit is connected to the power generator through the force amplifying unit, wherein the force amplifyingunit converts the low rotating speed of the driving shaft into the high rotating speed and drives the power generator to generate power, and meanwhile the force amplifying unit converts the low resistance of the power generator into the high resistance and generates braking force on the driving shaft through the clutch unit. The service life of the automobile brake device is prolonged.
