電池修復儀:鉛酸電池的放電速(su)率和使用有何關系(xi)?　

　同樣功率的(de)電(dian)(dian)(dian)動(dong)機(ji),額(e)定電(dian)(dian)(dian)壓不(bu)同,耗(hao)電(dian)(dian)(dian)的(de)速度絕對不(bu)同.比如:同是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(liu)為(wei)(wei)7.5A;而額(e)定電(dian)(dian)(dian)壓為(wei)(wei)36V時,電(dian)(dian)(dian)流(liu)只有5A,它們(men)用同樣容量的(de)電(dian)(dian)(dian)池(chi)組,組合為(wei)(wei)36V,以(yi)5A電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian),電(dian)(dian)(dian)化反(fan)(fan)應(ying)(ying)緩(huan)慢,而組合為(wei)(wei)24V,以(yi)7.5A電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian),電(dian)(dian)(dian)化反(fan)(fan)應(ying)(ying)就會相對激烈(lie),不(bu)如以(yi)5A放電(dian)(dian)(dian)從容.

　　電(dian)池(chi)以0.5C以下的電(dian)流放電(dian)才是(shi)經濟的.什么叫0.5C?C:表示的是(shi)電(dian)池(chi)的容量(liang)(liang)(liang),C2表示用(yong)2小時(shi)放時(shi)率放電(dian)時(shi)對電(dian)池(chi)測定(ding)得(de)出的實際容量(liang)(liang)(liang).這就是(shi)說,對標定(ding)為C2容量(liang)(liang)(liang)時(shi),每小時(shi)應(ying)當放出一(yi)半(ban)的容量(liang)(liang)(liang)(0.5C2)才符合容量(liang)(liang)(liang)規定(ding),如果超(chao)過0.5C2,它的容量(liang)(liang)(liang)就要打折扣了.而且對電(dian)池(chi)壽命不利.

　　電(dian)池長時間(jian)(jian)工作,輸出(chu)的(de)工作電(dian)流不(bu)大于電(dian)池額(e)定(ding)容量Cx的(de)確/X,X是(shi)(shi)該項電(dian)池額(e)定(ding)值下(xia)的(de)時率,這是(shi)(shi)選擇(ze)的(de)原則.X是(shi)(shi)2,則應(ying)按(an)2小時放電(dian)時率;X值是(shi)(shi)3,則使用時間(jian)(jian)應(ying)按(an)3小時考(kao)慮.
