A high-power hybrid vehicle energy management method considering heat dissipation and energy consumption comprises the steps that the heating value of each component of a power system is calculated, and a heating model is established; establishing a cooling system heat dissipation power model through data fitting by taking the fan air volume and the water pump flow speed as control variables; and obtaining the required power of the whole vehicle by combining with the traction power requirement of the driving module based on a longitudinal kinetic equation, and performing energy management on the basis of the requirement. According to the method, heat dissipation energy consumption of the cooling system is introduced for energy management, and compared with a traditional control strategy formulated based on traction power, the adaptability of the control strategy is enhanced, and the energy consumption economical efficiency of the high-power hybrid power vehicle is improved.
