摘要
电动汽车在冬季行驶时,由于电池容量衰减、行驶阻力变化及空调能耗增加,续航里程严重缩短,对用户的使用造成极大不便。因此,对电动汽车冬季续航能力进行研究和评估对于用户和汽车生产商尤为重要。文章通过理论推导及实际试验验证数据对电池充放电特性、空调加热能耗及低温行驶阻力三方面影响因素进行分析,并建立电动汽车低温续航里程模型。
When electric vehicles are driving in winter, due to the attenuation of battery capacity, the change of driving resistance and the increase of air conditioning energy consumption, the endurance mileage is seriously shortened, which causes great inconvenience to users. Therefore, it is very important for users and automobile manufacturers to study and evaluate the winter endurance capability of electric vehicles. Based on the theoretical derivation and the actual test data, this paper analyzes the battery charging and discharging characteristics, air conditioning heating energy consumption and low-temperature driving resistance, and establishes the low-temperature range model of electric vehicles.
