【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.
[Abstract]:The on-board thermoelectricity generator (TEG) is a new type of device, which converts the heat energy from the exhaust gas to electric energy directly. With the development of thermoelectric material technology, the application of TEG in automobile becomes possible. In order to study the effect of installing this thermoelectric generator on fuel economy of vehicle, the Simulink simulation model of thermoelectric generator is established according to the basic theory of thermoelectric conversion. Then a top-level simulation model of parallel hybrid electric vehicle is built based on ADVISOR simulation platform. At the same time, a number of TEG simulation models are established with the physical prototype of the laboratory as the object. The concept of specific power of thermoelectricity generator is put forward by analyzing the obtained experimental data through simulation experiments. Based on this, the relationship between TEG configuration and fuel consumption is explained, which provides a theoretical basis for the development of a more efficient exhaust gas thermoelectric hybrid vehicle.
