電池修復儀:鉛酸電池的放電(dian)速率(lv)和使用有何關系?　

　同(tong)(tong)樣功率的電(dian)(dian)(dian)(dian)(dian)動機,額定電(dian)(dian)(dian)(dian)(dian)壓(ya)不同(tong)(tong),耗電(dian)(dian)(dian)(dian)(dian)的速度(du)絕對不同(tong)(tong).比如:同(tong)(tong)是180W的電(dian)(dian)(dian)(dian)(dian)動機,額定電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)24V時,電(dian)(dian)(dian)(dian)(dian)流(liu)為(wei)7.5A;而(er)額定電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)36V時,電(dian)(dian)(dian)(dian)(dian)流(liu)只有5A,它們用同(tong)(tong)樣容量的電(dian)(dian)(dian)(dian)(dian)池組(zu),組(zu)合(he)(he)為(wei)36V,以5A電(dian)(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)(dian)化(hua)反應緩慢(man),而(er)組(zu)合(he)(he)為(wei)24V,以7.5A電(dian)(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)(dian)化(hua)反應就(jiu)會相對激烈(lie),不如以5A放電(dian)(dian)(dian)(dian)(dian)從(cong)容.

　　電(dian)(dian)池(chi)以0.5C以下的(de)電(dian)(dian)流放電(dian)(dian)才(cai)是經濟的(de).什么叫0.5C?C:表示的(de)是電(dian)(dian)池(chi)的(de)容(rong)(rong)(rong)量,C2表示用2小時放時率(lv)放電(dian)(dian)時對電(dian)(dian)池(chi)測定(ding)得出(chu)的(de)實際容(rong)(rong)(rong)量.這就是說,對標(biao)定(ding)為(wei)C2容(rong)(rong)(rong)量時,每小時應當放出(chu)一半(ban)的(de)容(rong)(rong)(rong)量(0.5C2)才(cai)符(fu)合容(rong)(rong)(rong)量規定(ding),如果(guo)超過0.5C2,它(ta)的(de)容(rong)(rong)(rong)量就要(yao)打折扣了.而且(qie)對電(dian)(dian)池(chi)壽命不利.

　　電(dian)池長(chang)時間(jian)工(gong)作(zuo),輸(shu)出的(de)(de)工(gong)作(zuo)電(dian)流不大于電(dian)池額定容量Cx的(de)(de)確/X,X是(shi)該(gai)項(xiang)電(dian)池額定值(zhi)下的(de)(de)時率(lv),這是(shi)選擇的(de)(de)原則(ze)(ze).X是(shi)2,則(ze)(ze)應(ying)按2小時放(fang)電(dian)時率(lv);X值(zhi)是(shi)3,則(ze)(ze)使用時間(jian)應(ying)按3小時考(kao)慮.
