摘　　要：纯电动教练车采用蓄电池作为单一动力电源时,在动力性能、续航里程等方面存在着不足,很难满足高功率密度和高能量密度的要求,而蓄电池与超级电容在性能上具有很强的互补性.将能量密度高的蓄电池与功率密度高的超级电容通过DC/DC变换器连接到直流母线上构成电动教练车的混合动力电源系统,不仅使蓄电池能够避免大电流放电的冲击,延长蓄电池的使用寿命,而且使电动教练车供电系统能满足高能量密度的需求.仿真与实验结果表明,混合能源系统能够有效地增加电动教练车的续驶里程.Pure learn-driver vehicle battery as a single power supply,the dynamic performance,mileage and other aspects of the existing shortcomings,It is difficult to meet the requirements of high power density and high energy density,and the battery and super capacitor have strong complementary performance.The high energy density of the battery and high power density of the super capacitor is connected to the DC bus to form a composite energy system through DC/DC converter,which can avoid the high rate of current impact and extend the battery life,and can meet the demand of high energy density.The simulation and experimental results show that the hybrid energy system can effectively increase the driving range of the learner-driver vehicle.
