The invention provides an energy management control method and system for an extended-range electric vehicle, electronic equipment and a readable storage medium. The method comprises the steps that the total required power of the whole vehicle is obtained; according to a preset discrete rule, range extender output power and battery output power under all discrete working points meeting the total demand power are determined; acquiring the required heat load of the battery and the passenger cabin, correcting the fuel consumption rate of the range extender under each discrete working point according to the required heat load of the battery and the passenger cabin, and calculating the output power of the range extender according to the corrected fuel consumption rate of the range extender and the corrected output power of the range extender under each discrete working point. Determining the fuel consumption of the range extender under each discrete working point; acquiring a fuel-electricity equivalent factor of the battery, and determining the equivalent fuel consumption of the battery under each discrete working point according to the fuel-electricity equivalent factor of the battery and the battery output power under each discrete working point; and according to the fuel consumption of the range extender and the equivalent fuel consumption of the battery under each discrete working point, taking the output power of the range extender and the output power of the battery under the discrete working point meeting a preset optimization target as target output power. According to the method, on the basis of an existing equivalent fuel consumption minimum strategy, correction terms of heat loads required by the passenger cabin and the battery are introduced, the waste heat recovery income of the range extender is equivalent to heat efficiency, optimal control over the whole vehicle power can be achieved, and the total energy consumption of the vehicle is reduced.
