The invention relates to the technical field of pure electric vehicles, and especially relates to an energy recovery strategy setting method and device, electronic equipment and a storage medium. Themethod comprises the following steps: obtaining a vehicle speed time curve of a vehicle under a first preset working condition, and obtaining a to-be-determined deceleration set according to the vehicle speed time curve; obtaining a vehicle braking force and vehicle speed curve according to the to-be-determined deceleration set; performing decoupling adjustment on the vehicle braking force and vehicle speed curve according to the opening degree of a brake pedal to obtain a maximum regenerative braking force curve; and setting an energy recovery strategy for the vehicle according to the maximumregenerative braking force curve. By means of the method, decoupling of regenerative braking and active braking is achieved, and the energy recovery strategy is made to be close to the braking deceleration actually needed by the braking circulation working condition. And the braking energy recovery efficiency under a specific working condition method is remarkably improved.
