In this paper,the patent analysis of extended range electric vehicle (EREV)was carried out,with patent appli-cation regional distribution,patent application year distribution,main technology fields year distribution,main patent appli-cants 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 Chi-na had a certain competitiveness and cost advantage in the development of EREV.Moreover,the market and policy for ER-EV were positive.But China lagged behind in key technologies research and development,and was facing strong patent bar-riers.Accordingly,the countermeasures and suggestions for the development of EREV in China were presented.
