The invention relates to the technical field of vehicles, and provides an energy recovery method, device and equipment and a storage medium. The energy recovery method comprises the steps that according to the current sliding resistance, the current target acceleration, the whole vehicle mass and the wheel rolling radius, the current basic energy recovery torque is obtained; according to the current slope torque compensation value, the current torque error value and the historical accumulated torque error value, the current basic energy recovery torque is corrected, the current target energy recovery torque is obtained, and energy recovery is conducted based on the current target energy recovery torque; wherein the historical accumulated torque error value is the sum of torque error values of all historical energy recovery periods. According to the technical scheme, the problem that in the prior art, energy recovery is inaccurate due to the fact that a fixed energy recovery torque value is adopted for energy recovery can be solved.
