The invention relates to an energy storage power vehicle which is characterized by comprising a frame, wheels, a power mechanism, a speed regulation control mechanism and a gearbox mechanism. The energy storage power vehicle has the advantages that external energy can be converted into elastic potential energy by the power mechanism, the elastic potential energy can be stored by the power mechanism, stored elastic potential energy can be released as needed under the effect of the speed regulation control mechanism, and a gearbox output shaft of the gearbox mechanism can drive the wheels via differential mechanisms, universal joints and driving shafts; electric energy can be stored and utilized in the form of mechanical energy, integral procedures include physical change, and the stored energy is energy released by means of physical re-change reduction; optional harmful substances can be prevented when the energy is stored and released, the energy storage power vehicle is free of other safety risks or hazards or optional requirements on climatic environments and geographic environments and high in power output and power and is safe, and the energy can be prevented from being consumed or lost in long-term storage procedures and is low in loss when charged and discharged.
