Research on collaborative innovation of key common technologies in new energy vehicle industry based on digital twin technology

With the continuous innovation of technology in the automotive industry, some key technologies in the field of new energy vehicles have been incorporated into various fields. Correspondingly, the government has formulated a promotion strategy for the study of the automobile industry and has carried out key research on its automobile industry, which has greatly promoted the scale of the automobile industry in the market. By comparing the previous technology, intellectual property data and vehicle sales amount, it can be seen that the application of common technologies has affected the growth of the automobile industry. However, the overall vehicle sales are not good. There are not many companies whose automobiles enter the global market, which has outstanding features. The current problems and obstacles faced by the new energy vehicle industry are low willingness to spread, short spread paths and poor spread benefits. The biggest feature of digital twin technology is that it can dynamically simulate physical objects, and digital twin technology can dynamically simulate the automotive industry. Based on the digital twin technology, this paper studied the overall development of patent applications, the oil dependence of the automobile industry, and the production and sales of two types according to the key common technical problems encountered in the development of new energy vehicles. The results showed that the annual production of new energy vehicles has increased by 9.22%, and the annual sales has increased by 9.18%.
