電池修(xiu)復儀(yi):鉛酸電池的放(fang)電速(su)率和使用有何關系?　

　同樣功率的電動機,額定電壓不同,耗電的速度絕對不同.比如:同是180W的電動機,額定電壓為24V時,電流為7.5A;而額定電壓為36V時,電流只有5A,它們用同樣容量的電池組,組合為36V,以5A電(dian)流放(fang)電(dian),電(dian)化(hua)反應(ying)緩(huan)慢,而組合為24V,以7.5A電(dian)流放(fang)電(dian),電(dian)化(hua)反應(ying)就會相對激(ji)烈,不如以5A放(fang)電(dian)從容.

　　電(dian)(dian)(dian)(dian)(dian)池(chi)以0.5C以下的(de)(de)電(dian)(dian)(dian)(dian)(dian)流放電(dian)(dian)(dian)(dian)(dian)才是(shi)經(jing)濟的(de)(de).什么叫0.5C?C:表示的(de)(de)是(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)容(rong)量(liang),C2表示用2小(xiao)時(shi)放時(shi)率(lv)放電(dian)(dian)(dian)(dian)(dian)時(shi)對電(dian)(dian)(dian)(dian)(dian)池(chi)測定(ding)得出(chu)的(de)(de)實際容(rong)量(liang).這就(jiu)是(shi)說,對標定(ding)為(wei)C2容(rong)量(liang)時(shi),每小(xiao)時(shi)應當(dang)放出(chu)一半的(de)(de)容(rong)量(liang)(0.5C2)才符合容(rong)量(liang)規定(ding),如果超過0.5C2,它(ta)的(de)(de)容(rong)量(liang)就(jiu)要打(da)折(zhe)扣了.而(er)且對電(dian)(dian)(dian)(dian)(dian)池(chi)壽命不利.

　　電池長時間工作,輸出的工作電流不大于電池額定(ding)容量Cx的確/X,X是該(gai)項電(dian)池額定(ding)值下的時率(lv),這是選擇的原(yuan)則.X是2,則應按2小時放電(dian)時率(lv);X值是3,則使用時間應按3小時考慮(lv).
