Abstract：A fuzzy control strategy is proposed,which takes the temperature difference between the current moment and the average temperature in the past period as the input parameter of fuzzy control.Liquid refrigerant is prepared when the ambient temperature is low and stored until it is released when the ambient temperature rises,so as to reduce the overall energy consumption during the operation of electric vehicle.The results show that the faster the change frequency of ambient temperature or the greater the change of ambient temperature,the greater the energy-saving of electric vehicle air conditioning system;The optimization of fuzzy control strategy can save 66.9 kJ air conditioning energy consumption within 8 min of ambient temperature change,and the energy saving rate is 5.3％.
