To promote the development of China's new energy automobile industry and technology, the current status of several key links in China's new energy automobile industrial chain, including the integrated industry of new energy vehicles, key components, and infrastructures were systematically reviewed in this article, starting from the development status of domestic new energy vehicles. In addition to the progress made in domestic new energy vehicle technology, progress in power battery technology, driving motor technology, and fuel cell technology were summarized. Next, the gaps and deficiencies in the development of new energy vehicles in China were analyzed and summarized by benchmarking the technological frontiers of international pure electric vehicles, plug-in hybrid electric vehicles, fuel cell vehicles, power battery, and driving system. Based on the analysis of the current status, the existing problems in the development of new energy vehicles in China were extensively analyzed from six different aspects, namely strategic policy, core technology, research and development production, industrial system, demonstration and promotion, and product sales. Furthermore, the countermeasures and suggestions for the future industrial development of China's new energy vehicles and directions for technological breakthroughs were provided from six different aspects, namely top layer design, independent innovation, basic support, industrial ecology, support system, and business model. Finally, the development paths of domestic new energy automobile industry and technology for the future were discussed. In terms of industrial layout, enterprises dealing with vehicles and their related parts should be rationally arranged to promote enterprise clustering and industrial agglomeration. For pure electric vehicles, the development of an integrated electric chassis and the new power battery system should be prioritized. For plug-in hybrid electric vehicles, attention should be focused on high-performance hybrid powertrains and the dedicated engines and dynamic coordinated control technologies. For fuel cell vehicles, the development of fuel cell stacks and key materials should be the focus while considering the development of fuel cell systems and core components.
