该文从专利申请区域分布、专利申请年度分布、技术领域年度分布、专利申请人、核心专利等五个方面对增程式电动汽车开展专利分析,并基于专利分析结果及相关市场和政策环境,对我国增程式电动汽车的开发开展SWOT分析,指出我国在增程式电动汽车开发方面已具有一定的竞争实力,并在成本上具有优势,且具有市场利好和政策利好,但在关键技术研发方面还较为落后,且面临较强的专利壁垒。据此,给出我国增程式电动汽车产业发展对策建议。

In this paper, the patent analysis of extended range electric vehicle (EREV) was carried out, with patent application regional distribution, patent application year distribution, main technology fields year distribution, main patent applicants and core patents highlighted. Based on the patent analysis result, as well as relative market and policy environment, a further SWOT analysis towards the development of EREV in China was performed. The analysis results indicated that China had a certain competitiveness and cost advantage in the development of EREV. Moreover, the market and policy for EREV were positive. But China lagged behind in key technologies research and development, and was facing strong patent barriers. Accordingly, the countermeasures and suggestions for the development of EREV in China were presented.
