電池修復儀:鉛酸電池的(de)放電速率和使用有何(he)關(guan)系?　

　同(tong)(tong)(tong)樣(yang)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)(tong),耗電(dian)(dian)(dian)(dian)(dian)的速(su)度(du)絕對(dui)不同(tong)(tong)(tong).比如:同(tong)(tong)(tong)是180W的電(dian)(dian)(dian)(dian)(dian)動機,額定電(dian)(dian)(dian)(dian)(dian)壓(ya)為24V時,電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)為7.5A;而額定電(dian)(dian)(dian)(dian)(dian)壓(ya)為36V時,電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)只有5A,它們(men)用同(tong)(tong)(tong)樣(yang)容量(liang)的電(dian)(dian)(dian)(dian)(dian)池組(zu),組(zu)合(he)為36V,以5A電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)放電(dian)(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)(dian)化反應緩慢,而組(zu)合(he)為24V,以7.5A電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)放電(dian)(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)(dian)化反應就會相(xiang)對(dui)激烈(lie),不如以5A放電(dian)(dian)(dian)(dian)(dian)從容.

　　電(dian)(dian)池(chi)以(yi)0.5C以(yi)下的(de)(de)(de)電(dian)(dian)流放電(dian)(dian)才(cai)是(shi)(shi)經濟(ji)的(de)(de)(de).什么叫0.5C?C:表示的(de)(de)(de)是(shi)(shi)電(dian)(dian)池(chi)的(de)(de)(de)容量,C2表示用2小(xiao)時(shi)放時(shi)率(lv)放電(dian)(dian)時(shi)對(dui)電(dian)(dian)池(chi)測定得出(chu)的(de)(de)(de)實際容量.這(zhe)就是(shi)(shi)說,對(dui)標定為C2容量時(shi),每小(xiao)時(shi)應(ying)當放出(chu)一(yi)半(ban)的(de)(de)(de)容量(0.5C2)才(cai)符合容量規定,如果超過0.5C2,它的(de)(de)(de)容量就要打折扣了.而(er)且(qie)對(dui)電(dian)(dian)池(chi)壽命不利.

　　電池(chi)長時(shi)(shi)間工(gong)作,輸出的(de)工(gong)作電流不大于電池(chi)額(e)定容(rong)量(liang)Cx的(de)確/X,X是該項電池(chi)額(e)定值下的(de)時(shi)(shi)率(lv),這是選擇的(de)原則.X是2,則應按2小時(shi)(shi)放電時(shi)(shi)率(lv);X值是3,則使用時(shi)(shi)間應按3小時(shi)(shi)考慮(lv).
