摘要随着全球变暖,能源一天天紧张和空气严重污染,电动车成为一种新的代步工具越来越受欢迎,以其绿色环保,交通便捷,价格低廉等优势占领各大市场,基本每家每户都有一辆电动车。电动车充电器作为衡量一部优劣电动车的重要依据,也是顾客考虑消费的重要参数之一,普通的电动车充电器寿命短,充电慢,发生大量的硫化反应,产生大量的析气。充电不均衡,因此让充电器的寿命大大简短,使电动车的电力越来越少,根本不足以满足我们的日常交通需求。所以,我们开始寻求一种电动车智能充电器,根据普通的电动车充电器的缺点进行了相应的改正,本次设计采用了两种芯片,一种是AT89C52,另一种是LM331,之后应用所学的单片机知识和C语言知识共同设计出这款新型的智能充电器,采用电流型的控制方案,使其均衡充电,不影响充电器和电动车的寿命。利用创新的集成电路把控制芯片和大功率管集成在一起。主要用模拟智能充电器的各种输入信号完成该系统的硬件部分,C语言用来编程完成其软件部分,总体来说,该设计是基于C语言和单片机的智能设计。关键词:AT89C52;LM331;单片机;C语言;充电器;电池寿命ABSTRACTAsglobalwarmingandenergygrewtenseandseriousairpollution,electricvehiclesbecomeanewkindoftransportationhasbecomemoreandmorepopular,withitsgreenenvironmentalprotection,thetransportationisconvenient,thepriceislowwaitforanadvantagetocaptureeachbigmarket,everyhouseholdhasabasicelectricvehicles.Electriccarchargerasaimportantbasisofqualityelectriccarsisalsooneoftheimportantparametersofcustomersconsiderconsumption,generalelectriccarchargerisshorter,chargingslow,lotsofvulcanizationreaction,toproducelargeamountsofgas.Chargeimbalance,soletthelifeofthechargershortgreatly,makethevehicle'slessandless,tosatisfyourdailytrafficdemand.So,westarttolookforanintelligentelectriccarchargers,accordingtotheshortcomingsoftheordinaryelectriccarchargerforthecorrespondingcorrection,thisdesignUSEStwokindsofchips,onekindisAT89C52,theotherisaLM331,learnedaftertheapplicationofsinglechipmicrocomputerandtheClanguageknowledgetodesignanewtypeofintelligentcharger,usingcurrentmodecontrolscheme,makeitsequalizingcharge,donotaffecttheservicelifeofthechargerandelectricvehicles.Usingtheinnovationofintegratedcircuittocontrolchipwithhighpowertubeintegration.Mainlyusesimulationoftheintelligentchargerallkindsofhardwarepartstocompletethesystemoftheinputsignal,theClanguageprogrammingtocompletethesoftwarepart,ingeneral,thedesignisbasedonClanguageandsinglechipmicrocomputerintelligentdesign.Keywords:AT89C52;LM331;Singlechipmicrocomputer;TheClanguage;Thecharger;Batterylife目录摘要............................................................................................................................IABSTRACT..................................................................................................................II前言..........................................................................................................................1第一章绪论..................................................................................................................21.1课题背景.........................................................................................................21.2课题研究的目的和意义.................................................................................21.3电动车智能充电器的任务与要求.................................................................3第二章电动车智能充电器的方案设计......................................................................42.1电动车智能充电器的工...
