摘要
在构建特斯拉纯电动汽车核心和非核心技术演化研究框架的基础上,以美国专利数据库USPTO的特斯拉公司技术专利及其引用专利为数据源,构建特斯拉专利引文分析数据集,依据技术轨道识别原理,利用Pajek软件提取最大凝聚子群以及小的重要凝聚子群,识别特斯拉纯电动汽车核心和非核心技术领域,进行各技术领域主路径分析。研究发现,特斯拉纯电动汽车的核心技术领域是电池热管理系统,非核心技术领域有5个:电机技术、智能控制技术、电池过充电保护技术、电池泄压技术和乘客保护、车辆悬挂以及高效电池组等技术。本文对这些领域技术的历史脉络和未来趋势进行分析,其结果可为我国纯电动汽车产业及相关汽车企业把握纯电动汽车技术重点、选择研发方向、进行技术合作、提高研发效率提供决策参考。
A research framework is constructed on the core and non-core technology evolution of Tesla battery electric vehi- cle. With the data source of the Tesla patents and their references data in USPTO, a patent citation analysis data set of Tesla battery electric vehicle（BEV） is built. According to the principle of technological evolution path identification, the largest converged sub-groups and smaller key converged sub-groups are extracted with Pajek, the core and non-core technology are- as of Tesla are identified and the main path is analyzed. Findings of the study are as follows ： battery thermal system for vehi- cle are the core technology of Tesla, five non-core technology areas include：motor technology, intelligent control, battery pack overcharge protection, battery pressure relief technology and passenger protection, suspension system for a vehicle, high efficiency battery pack as well. Analysis of the evolution history and future trends of Tesla battery electric vehicle technology will provide some decision reference on identifying the technical focus, selecting R＆D target, carrying out technical coopera- tion and improving innovation efficiency for battery electric vehicle industry and related enterprises in China.
