摘　　要：纯电动汽车的技术愈发成熟,应用规模和市场保有量持续上升。但是,高寒环境下的续驶里程衰减问题依然为用户带来了严重焦虑。对此,本文基于GB/T 18386.1-2021电动汽车能量消耗量和续驶里程试验方法 第1部分:轻型汽车,充分考虑高寒地区的道路条件和气象条件,创新性地开发了一套纯电动汽车高寒续驶里程道路试验方法,并选取6款在售的纯电动汽车,开展试验研究和结果分析。经试验验证,该方法具备较好的试验一致性和可操作性,能够为整车企业的高寒研发工作以及行业内相关机构的高寒测评活动提供有效指导。The technology of pure electric vehicles has become increasingly mature,with their application scale and market share continuously growing.However,the significant reduction in driving range under extremely cold conditions remains a major source of anxiety for users.In response to this,based on the Test methods for energy consumption and range of electric vehicles-Part 1:Light-duty vehicles(GB/T 18386.1-2021),this article integrates the actual road and meteorological conditions in high-cold areas and develops a preliminary set of driving range road test methods for pure electric vehicles in high-cold environments.Six commercially available pure electric vehicles were selected for experimental research and result analysis.The test results demonstrate that this method exhibits good consistency and practicality,providing ef fective guidance for vehicle manufacturers' R&D ef forts in highcold environments and for relevant industry organizations' evaluation activities in such conditions.
