電池修復儀:鉛酸電池的(de)放(fang)電速率和(he)使用有何關系(xi)?　

　同(tong)樣功率的(de)電(dian)(dian)(dian)動(dong)機(ji),額(e)定電(dian)(dian)(dian)壓不同(tong),耗(hao)電(dian)(dian)(dian)的(de)速度絕對不同(tong).比如:同(tong)是180W的(de)電(dian)(dian)(dian)動(dong)機(ji),額(e)定電(dian)(dian)(dian)壓為(wei)(wei)24V時,電(dian)(dian)(dian)流為(wei)(wei)7.5A;而(er)(er)額(e)定電(dian)(dian)(dian)壓為(wei)(wei)36V時,電(dian)(dian)(dian)流只有(you)5A,它們用同(tong)樣容量(liang)的(de)電(dian)(dian)(dian)池組(zu),組(zu)合為(wei)(wei)36V,以5A電(dian)(dian)(dian)流放電(dian)(dian)(dian),電(dian)(dian)(dian)化(hua)反(fan)應緩慢,而(er)(er)組(zu)合為(wei)(wei)24V,以7.5A電(dian)(dian)(dian)流放電(dian)(dian)(dian),電(dian)(dian)(dian)化(hua)反(fan)應就會相對激(ji)烈,不如以5A放電(dian)(dian)(dian)從(cong)容.

　　電池以(yi)(yi)0.5C以(yi)(yi)下(xia)的(de)電流放電才(cai)是經濟的(de).什(shen)么叫0.5C?C:表示的(de)是電池的(de)容(rong)(rong)量(liang)(liang)(liang),C2表示用2小時放時率放電時對電池測(ce)定(ding)(ding)得出的(de)實際容(rong)(rong)量(liang)(liang)(liang).這(zhe)就(jiu)(jiu)是說,對標定(ding)(ding)為C2容(rong)(rong)量(liang)(liang)(liang)時,每小時應(ying)當放出一半的(de)容(rong)(rong)量(liang)(liang)(liang)(0.5C2)才(cai)符合容(rong)(rong)量(liang)(liang)(liang)規(gui)定(ding)(ding),如果(guo)超過0.5C2,它的(de)容(rong)(rong)量(liang)(liang)(liang)就(jiu)(jiu)要打折(zhe)扣了.而且(qie)對電池壽命不(bu)利(li).

　　電池長時(shi)間(jian)工作,輸出(chu)的(de)(de)工作電流(liu)不大(da)于電池額定(ding)容量Cx的(de)(de)確(que)/X,X是(shi)(shi)(shi)該(gai)項電池額定(ding)值(zhi)(zhi)下(xia)的(de)(de)時(shi)率,這是(shi)(shi)(shi)選(xuan)擇(ze)的(de)(de)原則.X是(shi)(shi)(shi)2,則應按2小(xiao)時(shi)放電時(shi)率;X值(zhi)(zhi)是(shi)(shi)(shi)3,則使用時(shi)間(jian)應按3小(xiao)時(shi)考(kao)慮.
