Development Trend Of Patent Data Based Electric Car

In recent years, the rapid development of China’s auto market has attracted many multinational automobile companies and domestic capital investment in the automotive industry. This makes China’s automotive industry experience short-term shortage stage soon transferred to the fierce market competition stage, and to some extent, showed overcapacity. But the engergy crisis brought about by the traditional car and the increasingly serious environmental pollution problems, the development of new energy vehicles, especially electric will be a hight priority, an important way of ease and improve the plight of the automobile industry. Electric vehicles in terms of energy-saving, environmental protection and noise reduction has shown great advantages.After China’s accession to the WTO, the competitive environment faced by the electric vehicle market is more complex, many countries and companies have chosen to apply for a patent to protect its own technology. Patent has a huge number, wide technical, release the many advantages such as fast, innovative content in detail.Through an analysis of a technology patent, we can analyze trend in the area, grasp competitors technological development, and find out the patented invention output of large amount of people and worked in the corporate as well as to explore new technical and other information, so as to provide the basis for enterprises to develop R&D strategy.Based on the domestic and foreign related theory, combined with the patent map and data mining theory and method, this paper carried out a detailed analysis of the electric vehicle technology patent. Through the analysis of technology information in patent documents, it is easy to understand the complexity of proprietary information so as to provide the basis for enterprise to make development decisions. In this paper, from the aspects of the patented invention, patented technology, the relationship between patents overall trends and patented technology category of electric vehicle technology patent statistical analysis, a variety of charts to show up, you can understand the development of electric vehicles in China Patentpattern, development trend and the main research areas of technology, we can also see that at present our country what are the main enterprises in a favorable competitive position in the electric car research and development. Layout of the main category of technology, patent technology for electric cars, as well as technology trends and other aspects of the statistical analysis can further understand and grasp the development of electric vehicle technology and trends, we can understand the overall situation of electric vehicle development in China, enterprises so as to develop a more comprehensive research strategy. Finally, aiming at the problems, this article proposed for the development of China’s electric vehicle technology related countermeasures.
