電(dian)池修復儀:鉛(qian)酸(suan)電(dian)池的放電(dian)速(su)率(lv)和使用(yong)有何關系?　

　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,組合為(wei)36V,以5A電(dian)流(liu)放電(dian),電(dian)化反應緩(huan)慢,而組合為(wei)24V,以7.5A電(dian)流(liu)放電(dian),電(dian)化反應就會(hui)相對(dui)激烈,不如以5A放電(dian)從(cong)容.

　　電(dian)(dian)(dian)池以0.5C以下(xia)的(de)(de)電(dian)(dian)(dian)流放電(dian)(dian)(dian)才是(shi)經濟的(de)(de).什么叫0.5C?C:表(biao)(biao)示(shi)的(de)(de)是(shi)電(dian)(dian)(dian)池的(de)(de)容(rong)(rong)量,C2表(biao)(biao)示(shi)用2小(xiao)(xiao)時(shi)(shi)放時(shi)(shi)率放電(dian)(dian)(dian)時(shi)(shi)對(dui)電(dian)(dian)(dian)池測定得(de)出(chu)的(de)(de)實際容(rong)(rong)量.這就(jiu)(jiu)是(shi)說,對(dui)標定為C2容(rong)(rong)量時(shi)(shi),每小(xiao)(xiao)時(shi)(shi)應當放出(chu)一(yi)半的(de)(de)容(rong)(rong)量(0.5C2)才符合容(rong)(rong)量規定,如果超過0.5C2,它(ta)的(de)(de)容(rong)(rong)量就(jiu)(jiu)要(yao)打折扣了.而且(qie)對(dui)電(dian)(dian)(dian)池壽命不(bu)利.

　　電池長時間工作,輸出的工作電流不大于電池額定(ding)容量Cx的確/X,X是(shi)(shi)該項電池額定(ding)值(zhi)下的時率,這是(shi)(shi)選擇(ze)的原(yuan)則.X是(shi)(shi)2,則應(ying)按2小時放電時率;X值(zhi)是(shi)(shi)3,則使用時間(jian)應(ying)按3小時考慮.
