[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.
