Energy Consumption Characteristics of Electric Vehicles with Different Driving Behaviors

作为缓解能源危机和大气污染的有效措施,新能源汽车逐渐成为汽车工业的发展趋势,也是我国战略性新兴产业之一。为了缓解消费者的里程担忧,优化车辆设计和制造环节,实现路网交通体系的节能减排,有必要对电动汽车的能耗进行分析和评估。除了车辆自身参数等客观因素的影响外,电动汽车实际行驶过程中的能耗主要受到驾驶行为的影响,基于驾驶行为研究能耗有利于节能驾驶的推广。主要从驾驶行为的角度对纯电动汽车的能耗影响进行研究,试验车辆以标准驾驶行为、粗暴驾驶行为完成WLTC、CLTC试验循环,分析试验过程中的瞬时放电量,结合试验能耗数据,分析不同驾驶行为下电动车能耗特性。

As an effective measure to alleviate energy crisis and air pollution,new energy vehicles have gradually become a development trend in the automotive industry and one of China′s strategic emerging industries.In order to alleviate consumers′concerns about mileage,optimize vehicle design and manufacturing processes,and achieve energy conservation and emission reduction in the road network transportation system,it is necessary to analyze and evaluate the energy consumption of electric vehicles.In addition to the influence of objective factors such as vehicle parameters,the energy consumption of electric vehicles during actual driving is mainly influenced by driving behavior.Studying energy consumption based on driving behavior is conducive to the promotion of energy-saving driving.This article mainly studies the energy consumption impact of pure electric vehicles from the perspective of driving behavior.The test vehicles complete the WLTC and CLTC test cycles with standard driving behavior and rough driving behavior,the instantaneous discharge during the test process is analyzed.According to the test energy consumption data,the energy consumption characteristics of electric vehicles under different driving behaviors are analyzed.
