2023年第3期【摘要】为定量评估电动汽车用户的充电习惯和驾驶习惯,为电池故障诊断提供有效支撑,基于电动汽车的实际运行数据,提出了一种在役动力电池使用行为的分析方法。提取基于隶属度函数的动力电池使用行为特征参数,定义并计算出使用行为所累积的风险,即使用行为分数,并采用横、纵向对比的思想定量分析了单车在不同时间维度以及车车之间的电池使用行为差异。试验结果表明,获得的电池使用行为分数与电池组电压一致性存在强正相关性,可以充分评估动力电池使用行为,为电池故障诊断提供数据支撑。主题词:动力电池充电习惯驾驶习惯隶属度函数中图分类号:U472文献标识码:ADOI:10.19620/j.cnki.1000-3703.20220223ResearchontheUseBehaviorsofData-DrivenVehiclePowerBatteryZhangFan1,2,XingZixuan2,WuMinghu1,WeiShaoyuan3,GaoYang3(1.HubeiUniversityofTechnology,Wuhan430068;2.HubeiEngineeringResearchCenterofNewEnergyandPowerGridEquipmentSafetyMonitoring,Wuhan430068;3.SunwodaElectronicsCo.,Ltd.,Shenzhen518108)【Abstract】Basedontheactualoperatingdataofelectricvehicles,thispaperproposedananalysismethodofin-servicepowerbatteryusagebehaviors,soastoquantitativelyevaluatethechargingbehaviorsanddrivingbehaviorsofvehicles,andprovideeffectivesupportforbatteryfaultdiagnosis.Firstly,characteristicparametersofpowerbatteryusebehaviorsbasedonmembershipfunctionwereextracted,andthentheaccumulativeriskscoreofusingbehaviorswasdefinedandcalculated.Finally,thebatteryusebehaviordifferencesbetweenvehiclesandvehiclesindifferenttimedimensionswerequantitativelyanalyzedbyusingtheideaofhorizontalandverticalcomparison.Experimentalresultsshowthatthereisastrongpositivecorrelationbetweenthebatteryusingbehaviorscorequantifiedinthispaperandbatterypackconsistency,whichcanfullyevaluatetheusingbehaviorofpowerbattery,andprovidedatasupportforbatteryfaultdiagnosis.Keywords:Powerbattery,Chargingbehaviors,Drivingbehaviors,Membershipfunction张凡1,2邢子轩2武明虎1韦绍远3高洋3(1.湖北工业大学,武汉430068;2.新能源及电网装备安全监测湖北省工程研究中心,武汉430068;3.欣旺达电子股份有限公司,深圳518108)数据驱动的车载动力电池使用行为分析*汽车技术·AutomobileTe...
