Title the simulation research of electric vehicle that has the function of extended-range power
Abstract
As we all know, one of the ways to solve the energy crisis and environmental pollution is development electric vehicle. At present, owing to battery technology and battery charging time of electric vehicle, the driving range is limited，so interest is growing in range extender researches. In the paper, a ranger extender is applied on electric vehicle to extend mileage of electric vehicle , at the same time protect the battery performance and prolong battery life. And then the key technology on rang extender electric vehicle(REEV) which is from abroad or the nation is analyzed; the powerstrain is designed based on a pure electric vehicle before using advance electric simulator; a charging technology is proposed and a prototype is developed.
The design of powertrain is an basis of development of the electric vehicle which use an range extender. According to operating principle and driving characteristics, an methodology on designing range extender electric vehicle and design requirements are determine. On this foundation, the powerstrain component is choose and the main design parameters is defined. After that, the simulation software (ADVISOR) is applied for building range extender electric vehicle model and simulating vehicle performance(i.e. driving performance and economic performance) to provide a theoretical basis of prototype development.
