The invention provides an efficient braking recycle method for an electric-electric hybrid power system. The method includes the following steps of monitoring the speed of a whole vehicle and the voltage of a super capacitor in real time, calculating the kinetic energy E[p] of the whole vehicle and the energy E[c] capable of being absorbed by the super capacitor in real time, and controlling a DC/DC inverter to start at the optimal inversion conversion power P[o] when a braking signal is collected and E[c] is smaller than the product of E[p] and xi. The method is mainly for the optimization algorithm of the electric braking recycle of the hybrid power system of batteries and capacitors, it can be ensured that the kinetic energy of the whole vehicle is absorbed to the maximum degree, it can be ensured that the braking process of the whole vehicle is smooth as well, the braking comfort is high, and overcharge can not happen to super capacitors.
