Based on an analysis of a trend in global patent application and distribution of patented technologies for second life power batteries, as well as a discussion on the global competition situation and hotspots in R & D of technologies in this industry, the relevant patent application situation in China is analyzed. It is found that the number of applications for patents on second life power batteries in various countries is steadily increasing, and there is still room for improvement. The classification, detection, screening, and evaluation of retired power batteries have always been the hotspots in technical R & D and are still in development, for which the patent applications present stable upward trend. China, as a major source of relevant technologies, has been playing an important role in patent portfolio, which is consistent with global development trends. The applications for patents on relevant technologies are still expected to increase in the future. Therefore, it is recommended that relevant enterprises should intensify their efforts in R & D to seize opportunities in the industry, and also improve the patent portfolio.

Based on an analysis of a trend in global patent application and distribution of patented technologies for second life power batteries, as well as a discussion on the global competition situation and hotspots in R & D of technologies in this industry, the relevant patent application situation in China is analyzed. It is found that the number of applications for patents on second life power batteries in various countries is steadily increasing, and there is still room for improvement. The classification, detection, screening, and evaluation of retired power batteries have always been the hotspots in technical R & D and are still in development, for which the patent applications present stable upward trend. China, as a major source of relevant technologies, has been playing an important role in patent portfolio, which is consistent with global development trends. The applications for patents on relevant technologies are still expected to increase in the future. Therefore, it is recommended that relevant enterprises should intensify their efforts in R & D to seize opportunities in the industry, and also improve the patent portfolio.
