The invention discloses a power distribution method, device and equipment for a hybrid vehicle and a storage medium. The method comprises the steps that a first change curve and a second change curve are determined; based on the current engine rotating speed, the current maximum torque range of the engine, the current maximum torque range of the power generation motor and the current maximum torque range of the driving motor are determined; discretizing the current maximum torque range of the engine, the current maximum torque range of the power generation motor and the current maximum torque range of the driving motor, determining a plurality of torque combinations to be selected, and determining candidate torque combinations meeting preset conditions; determining candidate battery consumption power corresponding to each candidate torque combination; and determining a target torque combination under the current working condition based on the candidate engine oil consumption and the candidate battery consumption power corresponding to each candidate torque combination. According to the technical scheme, flexible distribution of power of the hybrid vehicle is achieved, the efficiency of the engine is improved, and energy waste is reduced.
