摘要
对电池健康状态(SOH)的中国专利申请数据进行挖掘和系统分析,总结中国SOH估算技术的专利申请情况,探讨中国SOH估算技术的研究现状与技术发展趋势。目前,SOH相关专利申请人主要是企业,研究重点是特征参数法,主要电池类型是锂离子电池。企业和相关研究机构可根据SOH估算技术的发展趋势来调整研究方向,发挥各自的优势,促进我国相关产业的技术发展。
Chinese patent application data of the battery state of health(SOH)were mined and systematically analyzed,the situations of the SOH estimation algorithm patent applications were summarized,the research status and development trends of the SOH estimation algorithm were discussed.At present,the patent applicants of SOH estimation patents were mainly enterprises,the research focus was the characteristic parameter method,and the mainly battery type was the Li-ion battery.Enterprises and related research institutions could adjust the research direction according to the technological development trend of SOH estimation technology,exert their respective advantages,and promote the technological development of related industries in China.
