The invention relates to an energy recovery method and device, a storage medium and a vehicle, which are applied to a pure electric vehicle and can improve the accuracy of slope estimation in an energy recovery strategy so as to improve the energy utilization rate of the whole vehicle and guarantee the braking safety and driving comfort of the vehicle. The energy recovery method comprises the following steps: acquiring a first slope value of the position of a vehicle from a gyroscope; acquiring a second slope value of the position of the vehicle and a third slope value of a road section in front of the vehicle from a high-precision map module; when the driving road condition of the vehicle is a slope road condition, determining a target slope value of the position where the vehicle is located according to the first slope value, the second slope value and the third slope value; and according to the target slope value, energy recovery is conducted on the vehicle.
