電池修復儀:鉛酸電池的放電(dian)速率和使用有何(he)關系?　

　同(tong)樣功率(lv)的(de)(de)電動(dong)機(ji),額定電壓(ya)(ya)不同(tong),耗電的(de)(de)速度絕對不同(tong).比如:同(tong)是180W的(de)(de)電動(dong)機(ji),額定電壓(ya)(ya)為24V時(shi),電流(liu)(liu)為7.5A;而額定電壓(ya)(ya)為36V時(shi),電流(liu)(liu)只有5A,它們用同(tong)樣容(rong)量的(de)(de)電池組,組合為36V,以5A電流(liu)(liu)放電,電化反(fan)應緩(huan)慢(man),而組合為24V,以7.5A電流(liu)(liu)放電,電化反(fan)應就會(hui)相對激烈,不如以5A放電從(cong)容(rong).

　　電(dian)(dian)池(chi)(chi)以(yi)0.5C以(yi)下的電(dian)(dian)流放(fang)(fang)電(dian)(dian)才(cai)是經濟的.什么叫0.5C?C:表示的是電(dian)(dian)池(chi)(chi)的容(rong)(rong)量(liang),C2表示用2小時(shi)(shi)放(fang)(fang)時(shi)(shi)率放(fang)(fang)電(dian)(dian)時(shi)(shi)對電(dian)(dian)池(chi)(chi)測定得出的實際(ji)容(rong)(rong)量(liang).這(zhe)就是說,對標定為(wei)C2容(rong)(rong)量(liang)時(shi)(shi),每小時(shi)(shi)應當放(fang)(fang)出一半的容(rong)(rong)量(liang)(0.5C2)才(cai)符(fu)合容(rong)(rong)量(liang)規定,如(ru)果超過0.5C2,它的容(rong)(rong)量(liang)就要打折(zhe)扣了.而且(qie)對電(dian)(dian)池(chi)(chi)壽命(ming)不利.

　　電(dian)(dian)池長時(shi)(shi)(shi)間工(gong)作,輸出的工(gong)作電(dian)(dian)流不(bu)大于(yu)電(dian)(dian)池額定容量Cx的確/X,X是(shi)(shi)該項電(dian)(dian)池額定值下的時(shi)(shi)(shi)率,這是(shi)(shi)選擇的原則(ze).X是(shi)(shi)2,則(ze)應按2小時(shi)(shi)(shi)放電(dian)(dian)時(shi)(shi)(shi)率;X值是(shi)(shi)3,則(ze)使用時(shi)(shi)(shi)間應按3小時(shi)(shi)(shi)考慮.
