電池修復儀:鉛酸電池的放電速(su)率(lv)和(he)使用(yong)有(you)何關(guan)系?　

　同(tong)樣功率(lv)的(de)電(dian)(dian)動(dong)機,額定(ding)電(dian)(dian)壓(ya)不同(tong),耗電(dian)(dian)的(de)速度絕對不同(tong).比如(ru):同(tong)是180W的(de)電(dian)(dian)動(dong)機,額定(ding)電(dian)(dian)壓(ya)為(wei)24V時,電(dian)(dian)流(liu)為(wei)7.5A;而額定(ding)電(dian)(dian)壓(ya)為(wei)36V時,電(dian)(dian)流(liu)只有5A,它們用同(tong)樣容量的(de)電(dian)(dian)池組(zu),組(zu)合為(wei)36V,以5A電(dian)(dian)流(liu)放(fang)(fang)電(dian)(dian),電(dian)(dian)化(hua)反(fan)應緩慢,而組(zu)合為(wei)24V,以7.5A電(dian)(dian)流(liu)放(fang)(fang)電(dian)(dian),電(dian)(dian)化(hua)反(fan)應就(jiu)會相對激烈,不如(ru)以5A放(fang)(fang)電(dian)(dian)從容.

　　電(dian)(dian)(dian)池以(yi)0.5C以(yi)下的(de)電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)才(cai)是(shi)經濟(ji)的(de).什么叫(jiao)0.5C?C:表示(shi)的(de)是(shi)電(dian)(dian)(dian)池的(de)容量(liang),C2表示(shi)用2小(xiao)時放時率放電(dian)(dian)(dian)時對(dui)(dui)電(dian)(dian)(dian)池測定得出的(de)實際容量(liang).這就是(shi)說,對(dui)(dui)標(biao)定為C2容量(liang)時,每小(xiao)時應當放出一(yi)半的(de)容量(liang)(0.5C2)才(cai)符(fu)合容量(liang)規(gui)定,如果(guo)超過0.5C2,它的(de)容量(liang)就要打折扣(kou)了.而且對(dui)(dui)電(dian)(dian)(dian)池壽(shou)命不(bu)利.

　　電池(chi)長(chang)時(shi)(shi)間(jian)(jian)工(gong)(gong)作,輸出(chu)的工(gong)(gong)作電流(liu)不大于電池(chi)額定(ding)容量Cx的確/X,X是該(gai)項(xiang)電池(chi)額定(ding)值下的時(shi)(shi)率,這是選(xuan)擇的原則.X是2,則應按2小(xiao)(xiao)時(shi)(shi)放電時(shi)(shi)率;X值是3,則使(shi)用時(shi)(shi)間(jian)(jian)應按3小(xiao)(xiao)時(shi)(shi)考慮.
