Relying on the unique technological advantages,the market size of range extended electric vehicle continues to expand,and user attention continues to rise.Meanwhile,the energy consumption performance of range extended electric vehicle in high-cold environment has attracted strong attention.In response to this,based on the Test Methods for Energy Consumption of Light-Duty Hybrid Electrie Vehicles(GB/T 19753-2021),this article is combined with the actual road and meteorological conditions in high-cold areas,and preliminarily develops a set of energy consumption road test method for range extended electric vehicle in high-cold environment.A certain range extended electric vehicle is selected for verification testing and result analysis.The experimental results show that this method has good consistency and operability.The all-electric range retention rate of this vehicle is 30.3%and the charge-sustaining cycle energy consumption growth rate is 21.6%in the high-cold environment.The work content of this article will provide effective guidance for the research finding of vehicle enterprises and the assessment activities of relevant institutions in the industry.
