论文题目：电动汽车的发展状况及趋势摘要近年来，随着经济发展，我国已迈进汽车社会。汽车保有量迅速增加，导致我国每年近一半的原油需要进口，过度依赖石油资源将制约我国经济的发展，甚至影响到国家利益。同时，为了建设资源节约、环境友好的和谐社会，倡导并鼓励研发、使用环保节能的新能源汽车，代表了世界汽车业发展的方向，也符合我们的国情。我国电动车研究领先于国际水平，实现了电动汽车自主创新和技术集成，形成了比较完整的产业布局。同时，在关键性零部件技术，如汽车燃料电池发动机、驱动电机、动力蓄电池等方面，已经取得了重大进展，形成了配套产业链,最有可能率先实现电动车大规模产业化应用。一汽、东风、奇瑞、比亚迪等大型汽车工业集团，已启动电动车项目产业化。但电动汽车市场推广和使用环境培育进程比较缓慢确是不争的事实。关键词：电动汽车充电站，发展趋势，混合动力，燃料电池，现状AbstractInrecentyears,witheconomicdevelopment,Chinahasbeenmovingvehiclecommunity.Carownershipincreasedrapidly,resultinginnearlyhalfofChina'sannualcrudeoiltobeimported,over-relianceonoilresourceswillrestrictthedevelopmentofoureconomy,andevenaffectthenationalinterest.Meanwhile,inordertobuildaresourcesaving,environment-friendlysociety,promotingandencouragingresearchanddevelopment,useofenvironmentallyfriendlyenergy-efficientnewenergyvehicles,representsthedirectionoftheworldautomobileindustryisalsoconsistentwithournationalconditions.OfelectricvehiclesinChinaaheadofinternationalstandards,andachievetheelectriccarinnovationandtechnologyintegration,formedarelativelycompleteindustriallayout.Atthesametime,technologyinkeycomponents,suchasautomotivefuelcellengine,drivemotors,powerrechargeablebatteryside,hasmadesignificantprogressinformingacompleteindustrialchain,mostlikelyShuaixianachieveelectricJuHuascaleindustrialapplications.FAW,Dongfeng,Chery,BYDandotherlargeautomotivegroup,haslaunchedtheindustrializationofelectricvehicleprojects.Buttheelectriccarmarkettopromoteandfostertheprocessofusingtheenvironmentmoreslowlyindeedisanindisputablefact.Keywords：ElectricVehicleChargingStation,trends,hybrid,fuelcell,present.目录1引言...........................................................................................................................................12电动汽车概述...........................................................................................................................12.1电动汽车的定义和分类..................................................................................................12.1.1电动汽车的定义..................................................................................................12.1.2电动汽车的分类..................................................................................................12.2电动汽车的历史..............................................................................................................42.3电动汽车的优势..............................................................................................................42.3.1良好的环境保护效果..........................................................................................52.3.2噪声低..................................................................................................................52.3.3热效率高..............................................................................................................62.3.4排放的废热少.................................................................................
