The invention discloses a range extender control method, system and device and a storage medium, and belongs to the technical field of new energy automobiles, a range extender controller sends corresponding control instructions to a generator controller and an engine controller based on a received control demand instruction sent by a whole vehicle controller, and the generator controller and the engine controller control the whole vehicle controller. The method comprises the following steps: receiving a control instruction and a preset operation torque corresponding to the control instruction, controlling a generator to operate according to the preset operation torque by a generator controller based on the control instruction so as to improve the rotating speed acceleration of an engine, and enabling the rotating speed acceleration and a resonance interval of a dual-mass flywheel to have an association relationship; the range extender controller controls the range extender based on the rotation speed change of the engine, so that the range extender can quickly cross the resonance rotation speed interval of the dual-mass flywheel in the operation process, the resonance impact time borne by the transmission shaft system structure is shortened, and therefore the transmission efficiency is improved. The reliability of the transmission shaft system structure in the operation process of the range extender can be improved.
