The invention provides a range extender power generation control method and device, electronic equipment and a storage medium. The method comprises the steps that the current range extender power generation mode of the vehicle is determined; according to the current-day minimum battery cell temperature of the vehicle, a battery remaining capacity threshold value corresponding to the range extender power generation mode in the current vehicle mode is determined; vehicle required power corresponding to the range extender power generation mode is determined, the economic rotating speed mapping relation is inquired, and the economic rotating speed of the engine is obtained; calculating the engine torque corresponding to the economic rotating speed and calculating the actual rotating speed of the generator by using a rotating speed and power relation formula; and the engine torque is sent to the engine so that the engine can execute engine torque control operation, and the actual rotating speed is sent to the generator so that the generator can execute rotating speed control operation. According to the application, the power protection capability of the extended-range electric vehicle in a low-temperature environment can be improved, and the generating capacity can be intelligently adjusted, so that the driving experience and satisfaction of a user are improved.
