2、raditional petroleum combustion engine, in which includes any nontraditional vehicle like, HEV, Plug In, EV, Fuel Cell, Bio fuel etc. that improves fuel economy. The development of electric vehicle has been over a hundred years but failure to gain the public acceptance in various stages due to vario

3、us reasons which explained. While EV was never mass produced, Hybrid electric vehicle gains the momentum in recent years. Ford has launched its second generation of HEV and GM also announced the debut of the Volt in 2010. Comparing to the regular HEV, Plug in is the new trend in hybrid auto developm

4、ent due to extend travel range in electrical mode and a possibility of a zero emission as long as travel distance is less than charging threshold. However, more recently, an electrification trend in automotive industry has been evolved and will revolutionize the industry. With the correct policy and

5、 government help and advancement of electric vehicle technology, the prospect of Electric Vehicle will be bright and the focus point of future development. INTRODUCTION As associated with energy independence and environmental issue, alternative fuel vehicle, especially Electric and Hybrid electric v

6、ehicle has become part of the government policy all over the world. The united State mandates a stricter fuel economy standard. China issued a new energy vehicle policy to accelerate & subsidize the deployment of electric this year and set a goal of 500k for 2011. Hong Kong also set a clear vision f

7、or EV application in the near future.As for the auto industry, a silent green resolution is undergo significant transformation after gasoline price rose significantly to exceed US$2 level and market demands for such vehicle. The industry introduced more fuel efficient HEVs and less polluted vehicles

8、 to the market. As Oil price surged rapidly during the last few years, the phenomenon has pushed pure electric vehicle development regaining traction among automakers and governments.The consumer market has brought significant gain in alternative fuel vehicle as well as HEV and electric vehicles. A

9、HEV study (Fig. 1) conducted by Polk & Company indicated an upward trend of market share of HEV sales in United State and Western Europe. An even bigger share of HEV and EV were predicted when they combined. In fact, selection of HEV models from OEMs have grown from two (Insight & Prius) in 2000 to

10、more than twenties as today. Sales of the HEV are in the fast track along with more than 300,000 HEV sold in 20072. Further known commitments of HEV and electric vehicle from OEM will improve the HEV production even more. Adding plug-in and electric vehicle to the line up will strengthen and acceler

11、ate the current electrification trend.Chevy Volt, the first plug-in hybrid, and a bunch of planned electric vehicles saluted for end consumer in the North America will lead to a round of new energy vehicle in the market. HISTORY OF ELECTRIC VEHICLE DEVELOPMENTThe development of electric vehicle has

12、a long history. Since the invention of electric motor, electric vehicle has been around for 150 years. From simple non-chargeable to modern state of art control system, the development of Electric vehicle can be classified into three stages:A. Early development stageElectric vehicle was considered a

13、mong the earliest automobile and well ahead of combustion engine. It dominated the vehicle registration with 3:1 comparing to gasoline vehicles in the late 1920s to 1930s and held most of the land vehicle performance record in early 1900s. It was a major transportation tool and widely used in the so

14、ciety for local transportation improved from horse carriages. Until 1930, electric vehicle leadership was overtaken by gasoline vehicle development and was never able to reclaim the status for following reasons: Maturity of Gasoline vehicle and can be mass produced at a reasonable cost. With the mas

15、s production of Model T & manufacture process revolution, vehicles became suddenly available to general public and proceed as a way to improve life; Gasoline vehicle took over as the leader and surpass electric vehicle both in performance and cost. Infrastructure improvement and demand of inter-city travel required a longer travel distance that was never able to exploit by electric vehicle before. Lacking of charge infrastructure development, reliable electricity transmission and limited travel distance, electric vehicle no longer suited for consum
