The invention relates to a range extender control method, system and equipment based on an application scene. The method comprises the steps that the current cooling liquid temperature of an engine is collected; determining a starting torque according to the current cooling liquid temperature, and controlling the engine to start according to the starting torque; collecting the current gradient, the current speed and the current altitude; determining a current road condition according to the current gradient, and obtaining to-be-generated power based on the current road condition and the current speed; comparing the current altitude with a preset altitude threshold value; if the current altitude is larger than the altitude threshold value, the to-be-generated power is adjusted according to an efficiency curve, target generated power is obtained, the efficiency curve is used for indicating the mapping relation among the torque, the rotating speed, the power and the efficiency of the range extender, and the target generated power is located in a target efficiency interval of the efficiency curve; and controlling the range extender to generate power according to the target generated power. By adopting the method, the compatibility of the control mode of the range extender in the prior art can be improved.
