鎳氫電池充電時間計算
鎳(nie)氫電(dian)(dian)池充電(dian)(dian)時間(jian)(jian)長短計算方法:電(dian)(dian)池容量除以充電(dian)(dian)電(dian)(dian)流(liu),再乘以系數1.2(或(huo)者1.1),時間(jian)(jian)單位為小(xiao)時。
步驟/方法
電(dian)池容(rong)量(liang)除以(yi)(yi)充(chong)電(dian)電(dian)流(liu),再乘(cheng)以(yi)(yi)系(xi)數1.2(或者1.1),時(shi)間(jian)單位為小(xiao)時(shi)。
例如(ru):某鎳氫(qing)電(dian)(dian)(dian)池的(de)容量(liang)為(wei)1200mA,充(chong)(chong)電(dian)(dian)(dian)器充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流為(wei)600mA,充(chong)(chong)電(dian)(dian)(dian)時間(jian)即為(wei)(1200mA/600mA)×1.2=2.4小(xiao)時,那么這塊鎳氫(qing)電(dian)(dian)(dian)池使用(yong)這個充(chong)(chong)電(dian)(dian)(dian)器的(de)充(chong)(chong)電(dian)(dian)(dian)時間(jian)就為(wei)2.4小(xiao)時。
鎳氫電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)時(shi)間(jian)和充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)的(de)關系為電(dian)(dian)(dian)(dian)池容量除以充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)得到充電(dian)(dian)(dian)(dian)時(shi)間(jian),考慮(lv)充電(dian)(dian)(dian)(dian)過(guo)程(cheng)中的(de)損耗,所以將計算得到的(de)充電(dian)(dian)(dian)(dian)時(shi)間(jian)再(zai)乘以1.1或者(zhe)1.2這(zhe)個常數。
根據標識(shi),你可以(yi)計算出(chu)個大概(gai)的(de)時間(jian)的(de)。如果它是普通(tong)的(de)充電(dian)器(qi),而且電(dian)流很(hen)小的(de)話,充電(dian)時間(jian)一定很(hen)長的(de)。
以上計算方法不適用于新電池。一般說來,新電池前三次充電時,尤其是鎳鎘電池和(he)鎳氫電(dian)池(chi),標(biao)準充電(dian)在(zai)15個小時(shi)左右(0.1C),這樣才能使電(dian)池(chi)的使用時(shi)間(jian)(jian)達到最大值。以后則可參(can)照上面的方法計算電(dian)池(chi)充電(dian)時(shi)間(jian)(jian)。
鎳氫電池的充電方法
科學(xue)的(de)充電(dian)方(fang)法可以延長鎳氫電(dian)池的(de)使(shi)用壽命。
1、一般情況下,新的鎳氫電池只有很少的電量,購買后要先進行充電然后再使用。但如(ru)果(guo)電(dian)(dian)(dian)池(chi)出廠(chang)時間短,電(dian)(dian)(dian)量很(hen)足,推(tui)薦(jian)先使用再充電(dian)(dian)(dian)。新的(de)鎳氫電(dian)(dian)(dian)池(chi)一般要(yao)經(jing)過3-4次的(de)充電(dian)(dian)(dian)和使用,性能(neng)才(cai)能(neng)發揮到最佳狀態。
2、鎳(nie)氫電池的記憶效應(ying)雖然小,最好還是每次(ci)(ci)使用完再(zai)充(chong)電,并且是一次(ci)(ci)性(xing)充(chong)滿,不(bu)要充(chong)一會用一會然后再(zai)充(chong)。這是“延年益壽”的重要一點(dian)。
3、充(chong)(chong)電的(de)時候(hou)(hou),要(yao)注意充(chong)(chong)電器(qi)周圍的(de)散熱(re)。不(bu)用的(de)時候(hou)(hou)要(yao)保持電池(chi)清(qing)潔,尤其是兩端的(de)觸點,必要(yao)時使用柔軟(ruan)的(de)干布輕擦。長時間不(bu)用的(de)話(hua),要(yao)把電池(chi)從電池(chi)倉(cang)中取出,置(zhi)于干燥的(de)環境中。
4、鎳氫電池在(zai)(zai)存(cun)放幾個(ge)月后,會進入一(yi)(yi)種“休眠”狀態,電(dian)(dian)池(chi)壽命大大降低。如果鎳(nie)氫(qing)電(dian)(dian)池(chi)已經放置了很長時間,建(jian)議先(xian)用慢充進行(xing)充電(dian)(dian)為宜。一(yi)(yi)般鎳(nie)氫(qing)電(dian)(dian)池(chi)在(zai)(zai)充電(dian)(dian)前,電(dian)(dian)壓(ya)是(shi)在(zai)(zai)1.2V以(yi)下,充滿后正常電(dian)(dian)壓(ya)在(zai)(zai)1.4V左右(you)。以(yi)此(ci)可以(yi)判斷(duan)電(dian)(dian)池(chi)是(shi)否已經充滿。
