Title Modeling and Simulation of a Hybrid Excitation Extended Range Electric Vehicle Abstract

In the environment of sustainable development, new energy vehicles is developing in a strong momentum, and it is gradually growing to be a emerging industries which can compete with the traditional automotive industry。Among them, the extended range electric vehicles, with its special advantages, is considered to be the optimal transition models in the transformation process of the auto industry's strategic direction at this stage, and has become a hot topic at present。This paper mainly build and research a dynamic model of a hybrid excitation Range extender, and simplify it to a mean value model of engine and a hybrid excited generator model, according to the mathematical model, using MATLAB / Simulink to build the dynamic model of the Range extender as the charged object ,analyze the working characteristics change laws with speed, power through simulation to optimize parameters, making the Range extender has better fuel consumption rate and efficiency in practical applications。

Keywords The range extender Mean value model Hybrid excitation motor Modeling and simulation
