Research On Development Of New Energy Vehicle Battery Based On Patent Analysis

With the rapid development of human society, energy crisis and environmental pollution is increasingly serious, new energy vehicles with energy clean, energy saving and emission reduction advantages, the global automotive companies will be the new energy automotive field as a new research focus, and battery technology as a new energy The only source of automotive power has become the focus of national strategic level support. In this paper, the new energy vehicle battery technology patent application as a data source, the use of statistical analysis methods and social network analysis methods,new energy vehicle battery technology development status and research, and China's new energy vehicle battery technology encountered in the development The problem was analyzed and the coping strategies were put forward. The main contents of this thesis include the following parts:The first part introduces the basic theory. On the basis of the research status of patent analysis, social network analysis and new energy automobile battery technology research at home and abroad, and the related knowledge theory, the author has carried on the corresponding sorting and induction. Patent analysis can be from the patent data to dig out a lot of competitive value of information, has become the current competitive intelligence analysis of the mainstream analysis of one of the methods. Social network analysis has a strong practicality, can be in numerical or graphical form to reveal the study of complex co-word network relationship, in all disciplines are applied. New energy car battery technology as the core technology of new energy vehicles, the current lithium battery has become the first choice for new energy vehicles.The second part is the development of new energy vehicle battery analysis. From the overall development of patent literature, the technical life cycle, the main competitive situation and other aspects of the patent data from the statistical analysis and found that the new energy vehicle battery technology is in the technology growth period, China's new energy vehicle battery technology development level and developed countries Compared to the existence of a large gap.The third part is the analysis of the new energy vehicle battery technology. The HO1M2/10 technology theme has always been the focus of research and development.At the same time, we should focus on the H01M10 (H01M10 / 10), and the H01M2 /10 technology topic has always been the focus of research. At the same time, we should focus on the H01M10 / 613 and H01M10 / 625 development of these two types of technical topics.The fourth part analyzes the existing problems in the development of new energy vehicle battery technology in China, and puts forward countermeasures and suggestions for the development of new energy vehicle battery technology from four aspects in combination with China's national conditions and the actual situation of the industry, and then promotes the new energy The development of automobile industry.
