電池修復儀:鉛酸電池的放電速率和使(shi)用(yong)有何關(guan)系?　

　同(tong)(tong)樣功率(lv)的(de)電(dian)(dian)(dian)動(dong)機(ji),額定電(dian)(dian)(dian)壓(ya)不(bu)同(tong)(tong),耗電(dian)(dian)(dian)的(de)速(su)度絕對不(bu)同(tong)(tong).比(bi)如:同(tong)(tong)是180W的(de)電(dian)(dian)(dian)動(dong)機(ji),額定電(dian)(dian)(dian)壓(ya)為24V時,電(dian)(dian)(dian)流(liu)為7.5A;而(er)(er)額定電(dian)(dian)(dian)壓(ya)為36V時,電(dian)(dian)(dian)流(liu)只(zhi)有5A,它們(men)用同(tong)(tong)樣容(rong)量(liang)的(de)電(dian)(dian)(dian)池組,組合為36V,以(yi)5A電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian),電(dian)(dian)(dian)化反應(ying)(ying)緩慢(man),而(er)(er)組合為24V,以(yi)7.5A電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian),電(dian)(dian)(dian)化反應(ying)(ying)就會相對激烈,不(bu)如以(yi)5A放(fang)電(dian)(dian)(dian)從容(rong).

　　電(dian)池以0.5C以下的(de)(de)電(dian)流放(fang)電(dian)才是經(jing)濟(ji)的(de)(de).什么(me)叫0.5C?C:表示的(de)(de)是電(dian)池的(de)(de)容量,C2表示用(yong)2小時放(fang)時率放(fang)電(dian)時對電(dian)池測定得出的(de)(de)實際容量.這(zhe)就是說(shuo),對標定為C2容量時,每小時應(ying)當放(fang)出一半的(de)(de)容量(0.5C2)才符(fu)合容量規定,如果超過0.5C2,它的(de)(de)容量就要打折扣了.而(er)且(qie)對電(dian)池壽命不(bu)利(li).

　　電池(chi)長時(shi)(shi)間(jian)工(gong)作(zuo),輸(shu)出的工(gong)作(zuo)電流不大于電池(chi)額(e)定容量Cx的確/X,X是該(gai)項(xiang)電池(chi)額(e)定值下的時(shi)(shi)率(lv)(lv),這是選擇的原則.X是2,則應按(an)2小時(shi)(shi)放電時(shi)(shi)率(lv)(lv);X值是3,則使用(yong)時(shi)(shi)間(jian)應按(an)3小時(shi)(shi)考(kao)慮.
