Abstract
Based on the search results of incoPat global patent database,the global application trend,key technologies and important applicants of power battery echelon utilization are analyzed.The re-search status and development trend of power battery echelon utilization related technologies are comprehensively and systematically reviewed.The results show that the patent applications in this field are generally increasing,and the patent applications are mainly Chinese applicants.The number of valid patents is large,and their operational value is high.Chinese patent applicants are mainly electric power companies and battery companies,with applicants mainly located in the eastern and central regions,especially in Guangdong and Beijing.Evaluation,sorting and safety management are the focus of research and development in this field,and they are also key technologies that urgently need further breakthroughs.Finally,putting forward five countermeasures and suggestions,in order to promote the high-quality development of the power battery echelon utilization industry.关键词
