摘要
目前相变冷却技术已经广泛用于新能源汽车电池的热管理,文章通过对新能源汽车电池相变冷却技术的专利情况进行检索、统计和分析,梳理了汽车电池相变冷却技术专利申请的趋势、重要申请人、技术分支及领域重要专利,列举了不同时期最具代表性的专利申请来分析车辆电池相变冷却技术的发展路线,指出了国内新能源汽车相变冷却领域的专利申请整体上突破性改进和创新不足,未来可以加强基础技术研发投入,推进技术创新和专利成果布局,充分发挥专利对科技创新的赋能作用,助力国内企业在全球市场竞争中占据优势地位。
Currently phase change cooling technology has been widely used for thermal management of new energy automotive batteries.Though patent retrieval,statistical analysis,and in-depth examination,this article system-atically investigates the trends,key applicants,technical subcategories,and pivotal patents in phase changing cooling technologies for automotive batteries.By examining representative applications across distinct developmental periods,the research delineates the evolutionary trajectory of phase-changing cooling technologies for automotive batteries.The findings highlight a notable lack of breakthrough improvements and insufficient innovation in the patent applications of phase change cooling of domestically,which future efforts should prioritize increased investment in foundational research and development,accelerate technical innovation and strategic patent portfolio deployment.By fully leveraging the enabling role of patents in empowering scientific advancement,domestic enterprises can secure a competitive edge in the global market.
