在此重要的是，充電不會影響鎳氫電池的壽命。完全充電后電荷不會關閉，因此選擇的電流非常小。這是為了防止電池在長期充電過程中過熱。對于鎳氫電池，電流值可降至0.05A。0.1A適用于鎳鎘電池。這些充電類型的限制只能是時間。要估計所需的時間，您需要了解容量。初次充電 的電池。要更準確地計算充電時間，您必須將電池放電。這將消除初始充電的影響。智能電池充電效率比其他類型低70％。那么現在讓我們仔細看看鎳氫電池一些充電方法。

鎳氫電池的高速充電方法介紹

鎳氫(qing)(qing)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)制造商提供充(chong)電(dian)(dian)(dian)特性，建(jian)議電(dian)(dian)(dian)流(liu)值(zhi)范圍為0.75至1A。選擇為電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)流(liu)時，請關注此(ci)值(zhi)。不(bu)建(jian)議使用(yong)超過此(ci)值(zhi)的(de)(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)，因為緊急(ji)安(an)全閥已打(da)開。建(jian)議在(zai)零下(xia)(xia)40攝氏度(du)，電(dian)(dian)(dian)壓(ya)(ya)0.8V，8V下(xia)(xia)對(dui)鎳氫(qing)(qing)電(dian)(dian)(dian)池(chi)(chi)進行高速(su)(su)充(chong)電(dian)(dian)(dian)。快速(su)(su)充(chong)電(dian)(dian)(dian)過程的(de)(de)效率遠(yuan)遠(yuan)大于下(xia)(xia)降速(su)(su)率，大約(yue)90％。但(dan)是(shi)在(zai)這個過程結(jie)束時，效率急(ji)劇下(xia)(xia)降，能量被(bei)加熱。電(dian)(dian)(dian)池(chi)(chi)內部(bu)的(de)(de)溫(wen)度(du)和壓(ya)(ya)力(li)將(jiang)急(ji)劇增(zeng)加。必須有(you)一個可以在(zai)壓(ya)(ya)力(li)增(zeng)加的(de)(de)情況(kuang)下(xia)(xia)打(da)開的(de)(de)緊急(ji)閥。在(zai)這種情況(kuang)下(xia)(xia)，電(dian)(dian)(dian)池(chi)(chi)的(de)(de)特性將(jiang)永(yong)久(jiu)丟失。是(shi)的(de)(de)，高溫(wen)本(ben)身對(dui)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)極的(de)(de)結(jie)構有(you)不(bu)利影響。因此(ci)，我們(men)需要明(ming)確的(de)(de)標準來(lai)停止結(jie)束流(liu)程。

鎳(nie)(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)要(yao)求(qiu)如(ru)下：目前，我們可以看到這(zhe)些(xie)存儲設備根據某些(xie)算法進行充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。在(zai)(zai)此階段，流過0.1A的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流并檢查極點處的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓必須小于(yu)1.8V才(cai)能(neng)開始(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。否則(ze)，該充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)將無法啟動。值(zhi)得(de)注意的(de)是，檢查電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)可用性是在(zai)(zai)不同(tong)階段完(wan)成的(de)。如(ru)果(guo)(guo)從充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)中取出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，則(ze)必須這(zhe)樣(yang)做。 如(ru)果(guo)(guo)存儲器(qi)邏輯(ji)確(que)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓大于(yu)1.8伏，則(ze)認為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)丟失或損壞。這(zhe)里確(que)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷的(de)粗(cu)略估計。如(ru)果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓低于(yu)0.8伏，則(ze)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)無法快(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。在(zai)(zai)這(zhe)種情況下，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)開啟預充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)模式。在(zai)(zai)正常操作(zuo)期間，鎳(nie)(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)很少放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)至低于(yu)1伏。因(yin)此，預充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)僅在(zai)(zai)嚴重放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和長(chang)期電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)存儲之后才(cai)被激活。

如上所述(shu)，當(dang)鎳氫電(dian)(dian)池(chi)嚴重放電(dian)(dian)時，預充(chong)電(dian)(dian)被激(ji)活。該(gai)步驟中的(de)電(dian)(dian)流(liu)(liu)設定為0.1-0.3A。此(ci)(ci)步驟時間有限(xian)，大約需要30分(fen)鐘。如果在(zai)此(ci)(ci)期間電(dian)(dian)池(chi)沒有恢復(fu)0.8伏的(de)電(dian)(dian)壓，充(chong)電(dian)(dian)將停(ting)止(zhi)。在(zai)這(zhe)種情況下，電(dian)(dian)池(chi)損(sun)壞(huai)的(de)可能性很高。在(zai)此(ci)(ci)階(jie)段，充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)逐(zhu)漸增(zeng)加(jia)。電(dian)(dian)流(liu)(liu)累積(ji)平穩地發(fa)生2至5分(fen)鐘。同時，如在(zai)其他步驟中一樣監測溫度，并(bing)將電(dian)(dian)荷與臨界值(zhi)分(fen)開(kai)。在(zai)此(ci)(ci)階(jie)段，充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)在(zai)0.5-1A的(de)范圍(wei)內。快速充(chong)電(dian)(dian)階(jie)段最重要的(de)是(shi)及(ji)時終止(zhi)電(dian)(dian)流(liu)(liu)。為此(ci)(ci)，在(zai)為鎳氫電(dian)(dian)池(chi)充(chong)電(dian)(dian)時，請根據各種標準使用控制器。

如果(guo)您不(bu)(bu)知道(dao)，則在(zai)(zai)(zai)充電(dian)(dian)(dian)(dian)(dian)期間使用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)增(zeng)量控(kong)(kong)制(zhi)方法。在(zai)(zai)(zai)調(diao)試過(guo)程中，它會不(bu)(bu)斷(duan)增(zeng)長，并(bing)(bing)在(zai)(zai)(zai)結(jie)束(shu)(shu)時(shi)開(kai)始下降(jiang)。通常，充電(dian)(dian)(dian)(dian)(dian)結(jie)束(shu)(shu)由30mV的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)決(jue)定。然(ran)而(er)，這(zhe)種用(yong)(yong)鎳氫電(dian)(dian)(dian)(dian)(dian)池(chi)控(kong)(kong)制(zhi)的方法沒有效果(guo)。在(zai)(zai)(zai)這(zhe)種情況下，與鎳鎘(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)的情況一樣，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)并(bing)(bing)不(bu)(bu)明(ming)(ming)顯。因此，您需要(yao)提高靈敏度才能開(kai)始使用(yong)(yong)。而(er)且，當(dang)對多個電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)時(shi)，操作將在(zai)(zai)(zai)不(bu)(bu)同時(shi)間發生(sheng)，并(bing)(bing)且整個過(guo)程將變(bian)(bian)得普遍(bian)。然(ran)而(er)，這(zhe)仍(reng)然(ran)是由于電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)下降(jiang)導致的電(dian)(dian)(dian)(dian)(dian)荷中斷(duan)的主要(yao)原(yuan)因。當(dang)用(yong)(yong)1A電(dian)(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)降(jiang)為-12 mV。有時(shi)，制(zhi)造商不(bu)(bu)會下降(jiang)，因為充電(dian)(dian)(dian)(dian)(dian)結(jie)束(shu)(shu)時(shi)沒有電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)變(bian)(bian)化(hua)。同時(shi)，在(zai)(zai)(zai)充電(dian)(dian)(dian)(dian)(dian)的前(qian)1到(dao)10分鐘期間關(guan)閉(bi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)增(zeng)量控(kong)(kong)制(zhi)。這(zhe)是因為當(dang)快速(su)充電(dian)(dian)(dian)(dian)(dian)開(kai)始時(shi)，電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)可(ke)能由于波動過(guo)程而(er)明(ming)(ming)顯改變(bian)(bian)。因此，在(zai)(zai)(zai)初始階段，關(guan)閉(bi)控(kong)(kong)制(zhi)以消除誤報。使用(yong)(yong)控(kong)(kong)制(zhi)和其他標準(zhun)是因為電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)差引起的電(dian)(dian)(dian)(dian)(dian)荷斷(duan)開(kai)的可(ke)靠性不(bu)(bu)是太高。

當鎳氫電池(chi)充(chong)電過(guo)(guo)程(cheng)結束時，溫度(du)(du)開(kai)始上(shang)升(sheng)。要排除操作(zuo)系(xi)統溫度(du)(du)的(de)值，請使用增量值而不(bu)是絕(jue)對值執(zhi)行監視(shi)。通常，充(chong)電終止標準導致溫度(du)(du)上(shang)升(sheng)超過(guo)(guo)每分鐘(zhong)1度(du)(du)。但是，這種(zhong)方法可能(neng)無(wu)法在低于(yu)0.5A的(de)充(chong)電電流(liu)下工作(zuo)，此(ci)時溫度(du)(du)上(shang)升(sheng)得足(zu)夠慢(man)。在這種(zhong)情況下，鎳氫電池(chi)可以(yi)(yi)充(chong)電。還有(you)一種(zhong)通過(guo)(guo)分析電壓(ya)(ya)導數來控(kong)制(zhi)充(chong)電過(guo)(guo)程(cheng)的(de)方法。在這種(zhong)情況下，不(bu)監控(kong)電壓(ya)(ya)差值并監控(kong)最大(da)增加率(lv)。使用此(ci)方法，您可以(yi)(yi)在充(chong)電完成(cheng)之前更快地停止充(chong)電。然而，這些控(kong)制(zhi)涉及(ji)許多困難，尤其(qi)是更精確的(de)電壓(ya)(ya)測量。

鎳氫電(dian)(dian)池用于(yu)充(chong)(chong)電(dian)(dian)的(de)一些充(chong)(chong)電(dian)(dian)器(qi) ，使用直(zhi)流(liu)(liu)和(he)直(zhi)脈充(chong)(chong)。這種負擔的(de)優點在于(yu)由于(yu)電(dian)(dian)池的(de)體積和(he)大晶(jing)體的(de)形成，專家們更均(jun)勻(yun)地要求活性材料的(de)分布。還報告了電(dian)(dian)流(liu)(liu)供應間(jian)隔(ge)之(zhi)間(jian)更精確的(de)電(dian)(dian)壓測量。已經提出反射充(chong)(chong)電(dian)(dian)作為(wei)該方法的(de)演變(bian)。在這種情況下，當(dang)施(shi)加脈沖電(dian)(dian)流(liu)(liu)時，電(dian)(dian)荷（1秒）和(he)放電(dian)(dian)（5秒）交替(ti)。低(di)于(yu)充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)的(de)放電(dian)(dian)電(dian)(dian)流(liu)(liu)是(shi)1到2.5倍。這些優點可以通過充(chong)(chong)電(dian)(dian)期間(jian)的(de)低(di)溫(wen)和(he)消(xiao)除大晶(jing)體的(de)形成來區分。

當給鎳氫電(dian)池充電(dian)時，根(gen)據(ju)各種參數控制充電(dian)過程的(de)(de)(de)結束(shu)是(shi)非常重(zhong)要的(de)(de)(de)。提供(gong)緊急停(ting)止(zhi)充電(dian)的(de)(de)(de)方法。為此，您可以使用絕對溫度(du)值(zhi)。通常這個(ge)值(zhi)是(shi)45攝氏度(du)。在這種情(qing)況下(xia)，您必須在冷卻后停(ting)止(zhi)充電(dian)并重(zhong)新(xin)開始。在此溫度(du)下(xia)，降(jiang)低了(le)提供(gong)鎳氫電(dian)池的(de)(de)(de)能力(li)。設置(zhi)結束(shu)的(de)(de)(de)截止(zhi)日期非常重(zhong)要。這可以根(gen)據(ju)電(dian)池的(de)(de)(de)容量，充電(dian)電(dian)流的(de)(de)(de)大(da)小和(he)過程的(de)(de)(de)效率來估(gu)計。限制設置(zhi)為估(gu)計時間(jian)加 5％。在這種情(qing)況下(xia)，如(ru)果先前的(de)(de)(de)控制方法不起作用，則在設定的(de)(de)(de)時間(jian)斷開充電(dian)。

充電階段

在(zai)此階段，充(chong)(chong)電(dian)電(dian)流設(she)定為0.1-0.3A。大約需要(yao)30分鐘。延長充(chong)(chong)電(dian)時間會縮短電(dian)池壽命(ming)，建議(yi)不(bu)要(yao)這樣做(zuo)。充(chong)(chong)電(dian)步驟有助于使電(dian)池的元件(jian)充(chong)(chong)電(dian)均勻。快速充(chong)(chong)電(dian)后，最(zui)好將電(dian)池冷(leng)卻至室溫并開始充(chong)(chong)電(dian)。然(ran)后電(dian)池恢復到最(zui)大容(rong)量。

充電(dian)(dian)(dian)過程完(wan)成(cheng)后，鎳(nie)鎘(ge)電(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)器通(tong)常(chang)會切換到滴注充電(dian)(dian)(dian)模(mo)式(shi)。鎳(nie)氫電(dian)(dian)(dian)池(chi)(chi)僅在您提供非(fei)常(chang)小的(de)電(dian)(dian)(dian)流（約0.005A）時才(cai)有用。這足以彌補(bu)電(dian)(dian)(dian)池(chi)(chi)座的(de)放(fang)電(dian)(dian)(dian)。

理想情況下(xia)(xia)，充(chong)電(dian)電(dian)池應具(ju)有(you)(you)在電(dian)池電(dian)壓(ya)下(xia)(xia)降時支(zhi)持充(chong)電(dian)的能力。只有(you)(you)在充(chong)電(dian)和使用(yong)電(dian)池之間經過了(le)足(zu)夠的時間后，支(zhi)持充(chong)電(dian)才有(you)(you)意義。

鎳氫電池的超快充電

還值得一提的(de)(de)是(shi)超快(kuai)速電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。眾所周知，當充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)容量高達70％時，鎳氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)效率(lv)接近100％。因此，在此階段增加(jia)加(jia)速通道的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)合理的(de)(de)。在這種情況下的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)限(xian)制(zhi)在10A。主要問題是(shi)確(que)定70％的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷應該將電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)降低到(dao)正常的(de)(de)快(kuai)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。這在很(hen)大程(cheng)度上取決(jue)于電(dian)(dian)(dian)(dian)(dian)(dian)池開始充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)量。高電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)很(hen)容易(yi)導(dao)致電(dian)(dian)(dian)(dian)(dian)(dian)池過熱(re)和電(dian)(dian)(dian)(dian)(dian)(dian)極結構破(po)壞。因此，如果您(nin)具備相(xiang)應的(de)(de)技能和經(jing)驗，建議(yi)您(nin)僅使(shi)用超快(kuai)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。
