Energy recovery technology can effectively enhance the energy efficiency and range of electric vehicles.This paper proposes an appropriate optimization method for the energy recovery control strategy of electric vehicles and conducts a multi-indicator analysis to explore its actual range improvement effect. The experiment uses a chassis dynamometer to simulate real road conditions，collects real data through the test vehicle，optimizes the intensity and adjustment mode of the vehicle's energy recovery，and improves the vehicle's range. By comparing the indicators such as energy recovery efficiency，smoothness，and economy before and after optimization，the effectiveness of the optimization strategy is verified. The results show that the optimized energy recovery control strategy has significantly improved in terms of enhancing energy recovery efficiency and range，and improving driving comfort.
