Abstract: Developing new energy vehicle (NEV) plays an important role in promoting the renewable energy applications and the development of electrified transportation technologies. The vigorous growth of NEV is considered to be effective for ensuring national energy security, alleviating energy shortages and improving environmental quality. At present, developing NEV has become a global consensus and collective action. NEV industry in China has made significant achievements, showing the characteristics of multi-industry integration. In this paper, the trend in the automotive industry was analyzed and six technological hotpots in the future were presented. Focusing on the goals of high efficiency, energy-saving, safety, comfort and all-climate applications, eight key technical directions of NEV were proposed for industrial integration. Analysis results show that, boosted by big data system, the large-scale commercial applications of NEV will be accelerated, and the deeper integration and sustainable healthy development of the industry will be realized.
