摘要
对"世界七国两组织"1972—2012年关于新能源汽车动力系统的专利数据进行检索。从宏观和微观层面针对新能源汽车动力电池的专利布局、专利功效手段等内容进行专利数据分析,从而对新能源汽车动力电池的关键技术热点和发展趋势进行预测。
Based on macroscopic and microscopic data analysis on new energy vehicles powertrain sys-tem, in the range of 7 countries plus 2 organizations （United States, United Kingdom, France, Ger-many, China, Japan, Switzerland, European Patent Office and World Intellectual Property Organiza-tion） from 1972 to 2012, the patent layout, patent effect and method and etc. were analyzed quanti-tatively. The hot spots and trends of new energy vehicles＇ battery technologies development have been predicted thusly.
