1、,The,design,of,the,lithium,battery,chargerIntroductionLi-Ion,rechargeable,batteries,are,finding,their,way,into,many,applications,due,to,their,size,weight,and,energy,storage,advantages.These,batteries,are,already,considered,the,preferred,battery,in,portable,computer,applications,displacing,NiMH,and,N

2、iCad,batteries,and,cellular,phones,are,quickly,becoming,the,second,major,marketplace,for,Li-Ion.,The,reason,is,clear.,Li-Ion,batteries,offer,many,advantages,to,the,end,consumer.,In,portable,computers,Li-Ion,battery,packs,offer,longer,run,times,over,NiCad,and,NiMH,packs,for,the,same,form,factor,and,s

3、ize,while,reducing,weight.,The,same,advantages,are,true,for,cellular,phones.,A,phone,can,be,made,smaller,and,lighter,using,Li-Ion,batteries,without,sacrificing,run,time.,As,Li-Ion,battery,costs,come,down,even,more,applications,will,switch,to,this,lighter,and,smallertechnology.,Market,trends,show,a,c

4、ontinual,growth,in,all,rechargeablebattery,types,as,consumers,continue,to,demand,the,convenience,of,portability.,Market,data,for,1997,shows,that,approximately,200,million,cells,of,Li-Ion,will,be,shipped,compared,to,600,million,cells,of,NiMH.,However,it,is,important,to,note,that,three,cells,of,NiMH,a

5、re,equivalent,to,one,Li-Ion,cell,when,packaged,into,a,battery,pack.,Thus,the,actual,volume,is,very,close,to,the,same,for,both.,1997,also,marked,the,first,year,Li-Ion,was,the,battery,type,used,in,the,majority,of,portable,computers,displacing,NiMH,for,the,top,spot.,Data,for,the,cellular,market,showed,

6、a,shift,to,Li-Ion,in,the,majority,of,phones,sold,in,1997,in,Europe,and,Japan.Li-Ion,batteries,are,an,exciting,battery,technology,that,must,be,watched.,To,make,sense,of,these,new,batteries,this,design,guide,explains,the,fundamentals,the,charging,requirements,andthe,circuits,to,meet,these,requirements

7、.Along,with,more,and,more,the,emergence,of,the,handheld,electric,appliances,to,the,high,performance,baby,size,weight,need,of,the,light,battery,charger,also,more,Come,more,big.The,battery,is,technical,to,progress,to,also,request,continuously,to,refresh,the,calculate,way,more,complicatedly,is,fast,wit
