摘　　要：车载温差发电器(TEG)是一种将汽车尾气中的热能直接转化为电能的新型装置,热电材料技术的日益进步使得TEG在汽车上的应用成为可能.为了研究加装这种温差发电器对车辆燃油经济性的影响,根据热电转换基本理论建立了温差发电器的Simulink仿真模型,然后基于ADVISOR仿真平台搭建了一种并联式混合动力汽车的顶层仿真模型.同时又以实验室物理样机为对象分别建立了多个TEG仿真模型,通过仿真实验对获得的实验数据进行分析后提出温差发电器比功率的概念,据此对TEG配置与整车油耗之间的相互关系进行了解释,为开发更加高效的尾气温差发电混合动力汽车提供了理论依据.The vehicular waste-heat thermoelectric generator（TEG）is a new device which can directly convert automobile exhausted waste-heat into electric energy;now advances in material technology have made it possible to apply the TEG to motor vehicles.To analyze the impact of the TEG applications on fuel economy of the vehicle,we established the Simulink sub-model of the thermoelectric generator system according to the theory of thermoelectricity;and continued to set up the backward simulation model of the parallel hybrid electric vehicle on the ADVISOR platform.And also,we established several other TEG models with different configuration referring to the laboratory physical prototypes.Running the computational procedure and finally proposed a concept of TEG power density after analyzing the experimental data.All these works lead to a final revelation of relationship between TEG configuration and automobile fuel economy,so as to provide a theory support for developing a more effective HEV based on the TEG system.
