Overall Design of a Miniature Pure Electric Vehicle
Abstract
Nowadays pure electric vehicle is more and more popular for the problem of environment pollution and worldwide energy shortage. With the development of urbanization, urban traffic congestion has affected many cities in China. Development of miniature pure electric vehicle can not only alleviate environmental problems, especially air pollution, but also make positive effort on improving urban traffic condition.
  Based on Dongfeng Fengshen E30L, this paper has done the overall design of a miniature pure electric vehicle. It includes the selection of main assembly components, design of the drive system, matching the power storage system and vehicle overall layout. Firstly it has made the selection of main assembly components and main parameters of the vehicle. Secondly it has designed the drive system including traction motor design and selection, transmission system design and check of dynamic requirements. It has put forward a new method to improve the dynamic performance. By planetary gear mechanism, the designed vehicle can shift gears to overcome gradient resistance. Besides, planetary gear mechanism also makes positive effort on acceleration condition and energy control. Thirdly, this paper has done the design of energy storage system and checks the drive range of designed vehicle. Based on ADVISOR, its drive range performance was simulated and analysed. It has check the drive range in three road conditions of CYC_ECE ,CYC_CONSTANT45 and CYC_EUDC_LOW. The results showed that efficiency of the traction motor plays a significant role in drive range. Finally, it has completed vehicle body design and body layout. It also concluded chassis layout and motion correction. Most information in this part is shown in engineering drawings.
