随着电动汽车在销量和市场占有率方面的快速提升，该类型车辆在适用性方面的痛点问题逐渐成为广大消费者的关注焦点。尤其是受冬季低温天气的影响，电动汽车续航里程大幅缩短、动力性下降、续航里程估计准确度降低、充电时间加长等问题，引发了不少用户的抱怨。本文结合中汽中心运营的CCRT（智能电动汽车）测评项目，验证了低温环境对电动汽车各方面的影响程度，评价分析了过去几年市场上主流电动汽车在耐低温性能方面的表现，同时就低温环境对电动汽车续航里程的影响进行了深入分析，并提出了对应的优化建议。
With the rapid increase in sales and market share of electric vehicles，the pain points found in the applicability of this type of vehicle has gradually become the focus of consumers. Especially affected by the low temperature weather in winter，the electric vehicle’s battery range is greatly shortened，power performance is reduced，accuracy of battery range estimation is reduced and charging time is lengthened，which has caused many users to complain. Combining with the EV-TEST project on electric vehicles operated by the China Automotive Technology & Research Center，this article verifies the impact of the low temperature environment on electric vehicles in all aspects，evaluates and analyzes the low temperature resistance performance of mainstream electric vehicles sold in the market in the past few years，conducts in-depth analysis on the influence of low temperature environment on the battery range of electric vehicles and puts forward the corresponding suggestions for optimization.
