The present invention discloses an optimized energy allocation method and system for an electric vehicle and an electric vehicle. The method includes step (1) detecting remaining charge levels of a first super-capacitor and a second super-capacitor, determining whether the remaining charge levels of the first super-capacitor and the second super-capacitor are greater than a preset threshold value, and if so, proceeding to step (2); step (2) acquiring a topographic map of a road ahead by means of an electric horizon system, predicting whether there is a continuous slope ahead, and if so, proceeding to step (3); and step (3) according to a continuous slope value ahead, predicting a braking force allocation proportion when carrying out braking ahead, allocating current power outputs of the first super-capacitor and the second super-capacitor in advance according to the braking force allocation proportion, and returning to step (1). By means of the present invention, the total capacity of the super-capacitors is increased, and the recovered braking or sliding energy is increased.
