| [Objective/Significance] As a leading city in China’s power battery industry, in-depth research and analysis of patent information in Changzhou is of great significance for gaining insights into industry development trends and clarifying technological innovation directions. This article aims to explore the core competitiveness of Changzhou’s power battery industry through patent data, identify technological evolution trends, layout of core patent holders, and hot technology areas, and provide strong support for Changzhou’s strategic decision-making and technological innovation. [Methods/Processes] Using the One Patent Data Service Platform as an analysis tool, a comprehensive search and in-depth analysis of relevant patents in the Changzhou power battery industry were conducted. Firstly, by analyzing the technological evolution trajectory through time series analysis, we can track the evolution process of key technologies from germination to maturity; Secondly, analyze the pattern of core patent holders and reveal the competitive situation and strategies of industry-leading enterprises in patent layout; Finally, focus on the distribution of hot technology fields and identify the current and future most promising technological directions. [Limitations] The research and development status of the foreign power battery industry has not been studied. [Results/Conclusions] The power battery industry in Changzhou has shown outstanding performance during the period of technological explosion, with a significant increase in patent applications. The battery manufacturing process and battery casing are the main research and development directions of Changzhou’s power battery industry, and innovation activities in the field of battery manufacturing technology are particularly active. The number of patents of Honeycomb Energy ranks first with a fault type advantage, and its technological innovation and research and development capabilities are outstanding. In the future, Changzhou can continue to strengthen its technological research and development in battery cooling systems, safety features, battery structures, and management systems. |
