電池修復儀:鉛酸電池的放(fang)電(dian)速率(lv)和使用有何關系?　

　同(tong)樣(yang)功率的(de)(de)電(dian)(dian)(dian)(dian)動機,額定(ding)(ding)電(dian)(dian)(dian)(dian)壓不同(tong),耗電(dian)(dian)(dian)(dian)的(de)(de)速(su)度絕對不同(tong).比如:同(tong)是180W的(de)(de)電(dian)(dian)(dian)(dian)動機,額定(ding)(ding)電(dian)(dian)(dian)(dian)壓為(wei)(wei)24V時,電(dian)(dian)(dian)(dian)流(liu)為(wei)(wei)7.5A;而(er)額定(ding)(ding)電(dian)(dian)(dian)(dian)壓為(wei)(wei)36V時,電(dian)(dian)(dian)(dian)流(liu)只有5A,它們(men)用同(tong)樣(yang)容量的(de)(de)電(dian)(dian)(dian)(dian)池組(zu),組(zu)合為(wei)(wei)36V,以(yi)5A電(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)化(hua)(hua)反應緩慢,而(er)組(zu)合為(wei)(wei)24V,以(yi)7.5A電(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)化(hua)(hua)反應就(jiu)會相對激烈,不如以(yi)5A放(fang)電(dian)(dian)(dian)(dian)從(cong)容.

　　電(dian)池以0.5C以下的(de)(de)(de)電(dian)流放(fang)電(dian)才是經濟的(de)(de)(de).什么(me)叫0.5C?C:表示的(de)(de)(de)是電(dian)池的(de)(de)(de)容(rong)量,C2表示用2小時(shi)放(fang)時(shi)率放(fang)電(dian)時(shi)對電(dian)池測定得出的(de)(de)(de)實際(ji)容(rong)量.這就(jiu)是說,對標定為C2容(rong)量時(shi),每小時(shi)應當放(fang)出一(yi)半的(de)(de)(de)容(rong)量(0.5C2)才符(fu)合容(rong)量規(gui)定,如果超(chao)過0.5C2,它(ta)的(de)(de)(de)容(rong)量就(jiu)要打折扣了.而(er)且對電(dian)池壽命不利.

　　電池長時(shi)(shi)間(jian)工作,輸出的(de)(de)工作電流不大(da)于電池額定(ding)容量Cx的(de)(de)確/X,X是(shi)(shi)該(gai)項電池額定(ding)值下的(de)(de)時(shi)(shi)率,這是(shi)(shi)選擇的(de)(de)原則(ze).X是(shi)(shi)2,則(ze)應(ying)按2小時(shi)(shi)放(fang)電時(shi)(shi)率;X值是(shi)(shi)3,則(ze)使(shi)用時(shi)(shi)間(jian)應(ying)按3小時(shi)(shi)考慮.
