Abstract: Abstract In the new energy automobile industry, a patent cooperation network is a technical means to effectively improve the innovation ability of enterprises. Network subjects can continuously obtain, absorb, and use various resources in the network to improve their research and development strength. Taking power batteries of new energy vehicles as the research object, this paper draws the patent cooperation network of power batteries of new energy vehicles by mining relevant patent cooperation data and analyzes the structure and spatial distribution characteristics of the patent cooperation network of power batteries of new energy vehicles from 2008 to 2021 based on two dimensions of time and space by using the social network analysis method. The evolution of the new energy vehicle power battery patent cooperation network has significant stage characteristics. The new energy vehicle power battery patent cooperation network shows great differences in the evolution process of each development stage and shows a diversified cooperation development trend. The intensity of patent cooperation varies greatly among provinces, and the level of cooperation in the eastern, southern, and central regions is significantly higher than that in the northern and western regions.
