The invention relates to the field of electric automobile, and aims at providing a test method and a test facility for recovering braking energy. In the test method and the test facility for recovering the braking energy, the test facility for recovering the braking energy comprises a motor, a transmission shaft, a back axle, inertia wheels, a braking device, a motor control cabinet, an entire vehicle control cabinet, a super capacitor, a storage battery and a frame base, wherein the motor, the transmission shaft, the back axle, the motor control cabinet, the entire vehicle control cabinet, the super capacitor and the storage battery are mounted on the frame base; the transmission shaft is connected with an output shaft of the motor. The test method and the test facility for recovering the braking energy have the beneficial effects that a test bed can simulate the braking process of a vehicle and the systemic analysis and research can be performed; the recovery effects of the braking energy in different proportions of regenerative braking and mechanical braking can be tested, so as to obtain an optimal control scheme of a braking energy recovery system; further, the better optimized design is made for a control system of the braking energy recovery system.
