The invention belongs to the technical field of electric vehicle braking energy recovery, and particularly relates to an electric vehicle braking energy recovery device which comprises a generator, a main shaft of the generator is connected with a speed adjusting mechanism, the speed adjusting mechanism comprises a driving wheel and a driven wheel, and the end face of the driving wheel and the end face of the driven wheel are provided with a plurality of linear track grooves in a penetrating mode in the radial direction. A plurality of rail grooves are evenly distributed in the circumferential direction of the end face, a driving belt support is slidably installed in the rail groove in the driving wheel, a driven belt support is slidably installed in the rail groove in the driven wheel, the driving belt support and the driven belt support make contact with a belt, and the driving belt support and the driven belt support are connected through a transmission adjusting mechanism. The transmission ratio of the driving wheel and the driven wheel is adjusted. By adjusting the transmission ratio of the driving wheel to the driven wheel, the power generator can generate power at the rated rotating speed, so that the power generation efficiency is improved, and the energy recovery efficiency is further improved.
