The invention discloses an electronic brake booster and an electro-hydraulic brake energy recovery system. The electronic brake booster comprises a brake pedal stroke detection unit used for detecting the brake stroke of a brake pedal, a brake piston stroke control unit used for controlling the brake stroke of a brake piston in a brake master cylinder according to an input brake piston stroke control instruction or the output torque of the brake pedal, a control unit used for controlling the brake pedal to be connected with the brake piston stroke control unit according to an input inputting instruction and controlling the brake pedal to be separated from the brake piston stroke control unit according to an input removal instruction, and an electronic control unit electrically connected with the three units and an automobile control unit. The electro-hydraulic brake energy recovery system comprises an electronic hydraulic brake subsystem comprising the electronic brake booster, a brake energy recovery subsystem and the automobile control unit. According to the invention, the problem of low energy recovery rate of the brake energy recovery system of the existing electric vehicle can be solved.
