小型纯电动乘用车集成设计方法研究
Integrated Design Method of Small Pure Electric Passenger Cars

纯电动汽车由于具有能源转化效率高、不依赖化石燃料以及“零排放”等特点，成为了汽车产业发展的热点方向。然而，中国新能源汽车的集成化技术还比较薄弱，技术水平和制造工艺技术还相对比较落后，许多方面还亟待改善。本文针对小型纯电动乘用车进行集成设计方法研究。开发全新结构的纯电动乘用车新平台的一体化底盘与轻量化车身，实现系统的模块化与整车的平台化。在车身结构、电池布置等进行优化设计，实现最小车身尺寸，对各零部件、整车进行了完善的试验验证，充分验证了整车的动力性、经济性、可靠性、安全性等各项性能，产品满足国家各项法规标准要求。在市区行驶灵活自如，节约城市道路资源，缓解拥堵问题，展现出强劲的市场竞争力。
Pure electric vehicles have become a hot topic in the development of the automotive industry due to their high energy conversion efficiency, non-dependence on fossil fuels and zero emissions. However, the integration technology of new energy vehicles in China is still relatively weak, the technical level and manufacturing process technology are relatively backward, and many aspects still need to be improved. This article focuses on the integrated design method of small pure electric passenger cars. An integrated chassis and lightweight body were developed for a new platform of pure electric passenger cars with a completely new structure, achieving modularity of the system and platform-isation of the entire vehicle. The design of the body structure, battery layout and other aspects were optimised to achieve the minimum body size. Full experimental verification was conducted on various components and the entire vehicle, fully verifying the performance, economy, reliability, safety and other characteristics of the vehicle. The product meets the requirements of various national regulations and standards. Driving flexibly and freely in urban areas, conserving urban road resources, alleviating congestion problems and demonstrating strong market competitive.
