The invention relates to a method and a system for recovering power of an electric vehicle. The method comprises the following steps of: calculating a recoverable rate of real-time brake energy recovery of a motor, and comparing the recoverable rate with a preset recoverable battery load value; therefore, the real-time brake energy recovery management of the motor is realized by managing the recovery rate of the real-time brake energy recovery of the motor, and compared with the existing problems of troublesome prediction and low accuracy caused by random allocation, the real-time brake energy recovery management of the motor is realized. According to the power recovery method and system for the electric vehicle in various embodiments of the invention, management of the recovery rate of real-time brake energy recovery of the motor can be realized, so that management of deployment management difficulty, operability and transverse difference of real-time brake energy recovery of the motor can be realized; the controllability of the wheel rotating speed control platform is improved, the power recovery efficiency is improved, and the system is suitable for uninterrupted power recovery.
