The invention discloses a range extender power following control method and device, relates to the technical field of vehicle control, and mainly aims to optimize NVH (Noise Vibration and Harshness) performance and dynamic property under a power following working condition so as to improve driving comfort. According to the main technical scheme, when the range extender is in the power following working condition, the generated power upper limit corresponding to the range extender is obtained, and the generated power upper limit is used for representing the maximum generated power corresponding to the range extender giving consideration to the NVH performance and the power generation performance at different vehicle speeds; when the upper limit of the generated power is smaller than the required power of the whole vehicle, the upper limit of the generated power serves as the actual generated power corresponding to the range extender; and when the upper limit of the generated power is greater than or equal to the required power of the whole vehicle, determining the actual generated power corresponding to the range extender according to a triggering condition corresponding to a battery compensation strategy. The method is used for controlling the power following of the range extender.
