電(dian)池修(xiu)復儀:鉛(qian)酸電(dian)池的放電(dian)速率(lv)和使用有(you)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(he)為(wei)36V,以5A電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)化反應緩慢,而組合(he)為(wei)24V,以7.5A電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)化反應就會相對激烈(lie),不如以5A放(fang)電(dian)(dian)(dian)(dian)從容.

　　電(dian)(dian)池以0.5C以下的(de)電(dian)(dian)流(liu)放電(dian)(dian)才(cai)是(shi)經濟的(de).什么叫(jiao)0.5C?C:表示的(de)是(shi)電(dian)(dian)池的(de)容(rong)(rong)量(liang),C2表示用2小時(shi)放時(shi)率放電(dian)(dian)時(shi)對(dui)電(dian)(dian)池測定(ding)(ding)(ding)得出的(de)實際容(rong)(rong)量(liang).這就是(shi)說(shuo),對(dui)標(biao)定(ding)(ding)(ding)為C2容(rong)(rong)量(liang)時(shi),每小時(shi)應當(dang)放出一半的(de)容(rong)(rong)量(liang)(0.5C2)才(cai)符合容(rong)(rong)量(liang)規定(ding)(ding)(ding),如(ru)果超過0.5C2,它的(de)容(rong)(rong)量(liang)就要(yao)打折(zhe)扣了.而且對(dui)電(dian)(dian)池壽命不利(li).

　　電池長時間工作,輸出的工作電流不大于電池額(e)定(ding)容(rong)量Cx的(de)確/X,X是(shi)該(gai)項(xiang)電池額(e)定(ding)值(zhi)下的(de)時(shi)率,這(zhe)是(shi)選擇的(de)原則(ze).X是(shi)2,則(ze)應(ying)(ying)按(an)2小(xiao)時(shi)放電時(shi)率;X值(zhi)是(shi)3,則(ze)使用時(shi)間(jian)應(ying)(ying)按(an)3小(xiao)時(shi)考(kao)慮.
