摘　　要：提出一种模糊控制策略,将当前时刻的温度与过去一段时间内的平均温度的温差作为模糊控制的输入参数,在环境温度低时制取液态制冷剂并储存,直至环境温度升高时释放,从而降低电动车运行过程中的整体能耗。结果表明,环境温度变化的频率越快或环境温度变化越大,电动车辆空调系统的节能量越大;通过优化模糊控制策略能够在环境温度变化8 min内节约66.9 kJ空调能耗,节能率达5.3%。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%.
