【正文】 ages as energy saving, low noise, zero emission, is one of the important direction of the development of new energy vehicles. Years of practice has proved that the present electrochemical batteries remain high internal resistance, short service life, high and low temperature working ability some shortings, can not fundamentally solve the short trip range of pure electric vehicles and to accelerate the problem of poor performance, greatly limits the application of pure electric vehicles. Super capacitor with low resistance, high working efficiency, and long cycle life, more suitable for large current charge and discharge frequently applied fields. In recent years, the super capacitor in the automotive application gradually bee a hot research topic in the field of energy, especially in hybrid vehicles, fuel cell cars and pure electric vehicles as a supplementary energy, bee the important direction of the electric posite power electric vehicle research covers the pure electric vehicles, hybrid electric vehicle and fuel cell electric vehicles and other direction,Research content including posite power supply performance of each ponent in the experiment, modeling, and how to system parameters matching and the study of parts to control. Such as: (1) the fuel cell and hybrid cars onboard posite research aspect of power supply. Dinapolia etc, depending on the vehicle mixed degree of posite power put forward different P/E, parameters matching and optimization design of the posite power supply. Andersson of containing nickel metal hydride batteries and ultracapacitors posite system such as the series HEV the matching of ponent parameters and simulation research. Schupbach, design theory and system optimization of posite power supply has carried on the thorough research, put forward the threestep design theory. Jilin university Yu Yuanbin on hybrid city bus is studied in this vehicle battery devices, mastered a lot of related data, the simulation research of various kinds of connection and the parameter matching form. Tsinghua university, with a number of units to share the country 863 fuel cell city bus topic,The final solution is also adopted the FC (fuel cell) + B (battery) + UC (super capacitor) structure. (2) battery and super capacitor of pure electric vehicles posite research aspect of power supply. Wight on loading of pure electric vehicles of ultraca pacitors under different condition of low temperature environment and the real vehicle road test and accelerated test drum test bench. The results showed that the super capacitor using make working load of the storage battery is able to slow down, the characteristics of super capacitor can rapid recovery of braking energy to make the vehicle fuel economy was improved. Beijing institute of technology with the north huade neoplan bus co., LTD. Jointly developed pure electric bus BFC6110 EV, which use lithium ion battery, super capacitor energy storage systems, and more advanced energy control system, ac drive system, through the vehicle test, the main performance index has reached a predetermined requirements. Beijing institute of technology in the development of pure electric vehicles equipped with super capacitor,Capacitance with battery and prolong the travel distance of the vehicle. Research shows that both at home and abroad, modeling simulation and performance testing method in its application in the posite power supply electric vehicle development process, but with the development of electric vehicle technology and the expansion of application scope, the electric car modeling simulation and performance analysis method of research still needs deepening and expansion. In this paper, we study pure electric vehicles will be introduced to the super capacitor energy storage system, establish a super capacitor posite power battery energy storage system, in view of the typical working conditions of the vehicle power demand curve corresponding to the current, according to the state of energy storage system, and the working mode of division, and coordination with proper energy management system in order to effectively make up for the defects such as battery low power density and low energy density, improve the pure electric vehicle power performance, extend the limited driving range.1 the typical working conditions of power demand analysis Pure electric vehicles when driving cycle test conditions, in order not to affect the vehicle39。同時他們?yōu)槲姨峁┝藢捤傻膶W習環(huán)境,使我有機會學習更多的知識。參考文獻. 電子電力學[D]. 高等教育出版社, 2003 ,687,陳偉,葉輝萍,等. 加裝超級電容純電動汽車的性能分析[J]. 機械工程學報, 2005, 41( 12) : 8286.,孫逢春,張承寧,等. 純電動大客車超級電容器參數(shù)匹配與實驗[J]. 電源技術(shù), 2004, 28( 8) : 483486, 507.
