A Development Analysis of Automotive Power Battery Testing Equipment in Jilin Province Based on Patent Data Resources of Jilin Provincial Library
The electrification of automobiles is an important way to achieve"carbon peak"and"carbon neu-trality".Electric vehicles cannot do without power batteries,and the types and accuracy of testing equipment also reflect the basic industrial capabilities of power batteries.Currently,patent analysis related to power batteries mostly focuses on the battery itself and control systems,lacking research and analysis on testing equipment.This article analyzes the global patent application situation of automotive power battery testing equipment,patent ap-plication situation in China,technological hot spots,main application institutions in China,applicant-source prov-inces and cities,patent layout status,patent application layout,and domestic patent layout of power battery test-ing equipment in areas with concentrated automotive industry from multiple perspectives,using patent data re-sources from Jilin provincial library and Incopat patent search and analysis software.The number of patent appli-cations in China accounts for about 90%of the global patent number,but the number of patent applications in this field in Jilin province is relatively small,and it has been in a stagnant state of low volume applications for a long time.When vigorously developing electric vehicles in the future,there may be patent risks.The patent applica-tions for power battery testing equipment in Jilin province are relatively concentrated,and the overall number of patent applications for small and medium-sized enterprises is relatively small.
