The invention discloses a braking energy recovery device for an electric vehicle. The braking energy recovery device comprises an overload protection mechanism, a self-adaptive flywheel energy storage mechanism and a stepless speed change mechanism. The invention belongs to the technical field of electric automobile kinetic energy recovery, and particularly relates to an electric automobile braking energy recovery device. According to the flywheel assembly, the rated rotating speed and the maximum limiting rotating speed are preset, when the flywheel reaches the rated rotating speed, software can stop kinetic energy storage, in case of software faults, power transmission can be forcibly cut off through a mechanical structure when the flywheel reaches the maximum limiting rotating speed, and therefore the power transmission efficiency is improved. Therefore, the rotating speed of the flywheel is controlled within a controllable range, and dangers are avoided.
