In this paper, on-car box-typed thermoelectric power generation system is abstracted into a mathematical model, using Matlab/Simulink software platform. The inputs are the speed and power of the engine, output is the power generated by the TEG system. The model is divided into two sub-models. One is the computing sub-model of the temperature of the TEG system, the other is the computing sub-model of the power generated by the TEG system. The temperature sub-model takes advantage of the output characteristics of the engine and the temperature data of the TEG system obtained on the bench and works out the fitting value of the temperature of the TEG system under all conditions of the engine by means of interpolation. It combines the engine and the TEG system and explores the relationship between them. And the power sub-model calculates the value of the power generated by the TEG system, using the basic thermoelectric principle. It combines the TEG system and on-car electric devices. The model can be used as a new power source - thermoelectric battery stack participating in the power flow of the vehicle, laying a solid foundation for subsequent simulation of the power, economy, emission performances of low hybrid vehicles based on thermoelectric power generation system.
