The Study Of Space Environment Design Of Automobile Based On The BEV Power Technology

A statistic data of NBS shows that the number of national civilian vehicles ownershipwas1.54billion which including9.72millions of motor tricycles and low-speed trucks at the endof2014, growth of12.4%compared to the previous year. The number of private car ownershipwas126000000, growth of15.5%compared to the previous year. In the background of globalenergy shortage and serious air pollution now, the consistent growth of the automobiles will leadto excessive consumption of energy and more serious air pollution. In order to solve the energyand pollution problems, the national "Twelfth Five-Year Plan" issued the effective measures thatthe new energy vehicles is not limited whatever number they have and line they drive, the newenergy bus official posts in Wuhan, Suzhou, Inner Mongolia and other places, recently announcedthe "energy-saving and new energy automotive industry development plan (2012-2020)" and thereduction of the new energy vehicle the purchase tax on the purchase cost straight down10%, aseries of policies that China is vigorously developing the domestic new energy vehicle market. Inaddition with the popularization of cars in each family of the city, the car had an impact oneveryone’s life, the automobile life style also influence people’s pursuit of fashion, green life, so itcan meet the needs of people living function instead of the traditional car is on the development ofnew energy vehicles requirements.New energy vehicles, including fuel cell electric vehicle (FCEV), hybrid electric vehicle(HEV),(BEV) pure electric cars, countries in the formulation of a series of encouraging thedevelopment of new energy vehicle policy at the same time, the research has also invested heavilyin power technology. But for pure electric vehicles, is a major technological breakthrough powersource (battery) and the drive motor technology development. BEV power technology based onthe current conditions, the market has been the emergence of a large number of pure electricvehicles, including the Chery QQ3EV, SAIC Roewe E50mature product, but also the emergenceof a large number of electric vehicle manufacturers in Hebei, Shandong, Jiangsu and other places.From the point of the pure electric car market, smart electric version of the popularamong urban women or lifted the tesla of electric wave or rural areas and small towns can be seeneverywhere in the pure electric vehicles at low speed, the basic is used for pure electric vehiclebody corresponding to have car body, the external shape and internal structure of space and so onall do not make change, and pure electric vehicles both in the structure of components andworking principle on having big distinction with traditional fuel vehicle, structure and technicaldifferences will lead to different space layout.This article is mainly for pure electric vehiclespower technology, the city’s environment system, residents travel mode and the consideration ofergonomics, systematically on the internal structure of pure electric vehicles battery, motor andother components in the space of rearranging planning, at the same time to study the effect of environment system of automobile outer space to define conform to the overall city environment system of pure electric car space, finally combining with the residents travel mode and research and analysis of man-machine engineering, guidance of pure electric vehicles in the middle of the human-computer interaction space decorate, by the Chinese and foreign in the third part of space planning and layout so as to put forward the definition of internal structure suitable for pure electric vehicles and use requirements of space arrangement.
