基于专利分析电动汽车产业主流技术趋势

摘要

Through researching technical features of the electric vehicle industry and technical characteristics and working in the distribution of the IPC classification retrieval, the paper was formed patent database of electric vehicle industry. On that basis, the technology of the electric car industry concentration and activity was analyzed in order to make clear the patent technology of the electric car industry layout and development trends, guide enterprise development planning and clear devel-opment keys.%通过对电动汽车产业的技术特征进行研究，围绕该技术特征和IPC分类展开检索工作，形成电动汽车产业的专利数据库，在此基础上对电动汽车产业的技术集中度和技术活跃度进行分析，以明确电动汽车产业的专利技术布局和发展趋势，指导企业的研发规划，明确研发重点。
