The invention provides a range extender point selection method, device and equipment and a storage medium, and the method comprises the steps: obtaining a plurality of comprehensive NVH parameters, a plurality of oil consumption parameters and a plurality of pure electric NVH parameters, constructing an NVH-range extender first mapping relation based on the NVH parameters and a rotation speed-torque relation, a second oil consumption-range extender mapping relation is constructed based on the oil consumption parameters and the rotating speed-torque relation, a third mapping relation is constructed based on the relation between the pure electric NVH parameters and the vehicle speed, and a comprehensive characteristic curve among the oil consumption, the vehicle speed and the rotating speed-torque is generated by combining the first mapping relation, the second mapping relation and the third mapping relation; oil consumption and power of the range extender with the to-be-selected point in different rotating speed-torque states are obtained, and a target point of the range extender with the to-be-selected point is obtained; the torque and the rotating speed of the range extender are comprehensively adjusted by combining the NVH parameters in the vehicle and the oil consumption parameters of the range extender, so that the optimal working point under the same output power is obtained, and point selection of the range extender is achieved.
