摘要
通过对复合电源在混合动力汽车(HEV)中应用的研究,设计了针对某款并联式混合动力汽车的复合电源结构,并对其效率特性进行了分析,提出了复合电源的功率分配控制策略以及电池给超级电容充电策略,基于MATALAB/Simulink,建立了复合能量存储系统模型,并嵌入ADVISOR软件中,在城市道路循环UDDS工况下进行了仿真研究。仿真结果表明,通过采用该复合电源控制策略,可以充分发挥超级电容和蓄电池各自的优点,改善整车储能系统的存储效率,提高制动能量的回收效率。
The application of composite power in hybrid electric vehicles was studied. The structure of composite power for a certain parallel hybrid electric vehicle was designed and its efficiency characteristic was researched. The strategy for con- trol of power distribution of composite power and the strategy for the batteries to charge the supercapacitor were estab- lished. The model of a composite energy storage system was established in MATALAB/Simulink. Then, the simulation model was embedded in the ADVISOR software and was simulated on the UDDS driving cycle. The simulation results show that the supercapacitor and batteries can give full play to their respective advantages when the control strategy of composite power is adopted, so the efficiency of the vehicle energy storage system can be enhanced and a higher efficiency of the braking energy recovery can be obtained.
