鎳氫電池（NiMH）的電(dian)荷算法(fa)類似于(yu)鎳鎘電(dian)池(chi)（NiCd），但鎳氫電(dian)池(chi)（NiMH）更(geng)復雜。用于(yu)檢測(ce)完全充電(dian)的負壓(ya)差(cha)是(shi)微弱的，尤其是(shi)在低于(yu)0.5C的充電(dian)時。不匹配或(huo)熱敷可以進一(yi)步減輕癥狀。

鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)（NiMH）充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器中的(de)(de)(de)NDV應響應每個電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)5mV或更低的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降。這需要(yao)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)濾(lv)波來補償(chang)由(you)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器引起的(de)(de)(de)噪(zao)聲和電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)波動。精心設計的(de)(de)(de)鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)（NiMH）充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器包括(kuo)NDV，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)平臺，Δ溫度（dT / dt），溫度閾值和超(chao)時定時器到(dao)(dao)(dao)完全充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)檢測(ce)算法。這些(xie)“或門”利用首先出現的(de)(de)(de)任何東西。許多充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器包括(kuo)30分(fen)鐘的(de)(de)(de)0.1C的(de)(de)(de)頂部充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，以將容量提高幾(ji)個百分(fen)點。一些(xie)先進的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器應用1C的(de)(de)(de)初始(shi)快速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。當(dang)達到(dao)(dao)(dao)某個電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)閾值時，會添加幾(ji)分(fen)鐘的(de)(de)(de)剩余時間，使電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)冷卻(que)下來。電(dian)(dian)(dian)(dian)(dian)(dian)荷以較低的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流繼續(xu)，然后(hou)隨著電(dian)(dian)(dian)(dian)(dian)(dian)荷的(de)(de)(de)進行進一步減少電(dian)(dian)(dian)(dian)(dian)(dian)流。該(gai)方案一直持續(xu)到(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)(dian)為止。這種(zhong)方法被稱為“階梯差(cha)分(fen)電(dian)(dian)(dian)(dian)(dian)(dian)荷”，適(shi)用于(yu)所(suo)有鎳基(ji)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。

采用(yong)階梯差(cha)分或其他(ta)激進充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方(fang)法(fa)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)比更基本的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)實現了(le)約6％的(de)(de)(de)容量(liang)增(zeng)益。雖然(ran)需(xu)要更高的(de)(de)(de)容量(liang)，但將電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)滿邊緣會(hui)增(zeng)加(jia)壓力(li)并(bing)縮短整(zheng)體電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)壽(shou)命。而不是達到(dao)預期(qi)(qi)的(de)(de)(de)350-400服務(wu)周(zhou)期(qi)(qi)，積極的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)可能會(hui)在(zai)(zai)300次循(xun)環后(hou)耗盡電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)組。鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiMH）不能過(guo)(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，涓流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設(she)定在(zai)(zai)0.05C左右。鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiCd）在(zai)(zai)吸(xi)收過(guo)(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方(fang)面更好(hao)，原(yuan)始的(de)(de)(de)鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiCd）充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)涓流電(dian)(dian)(dian)(dian)(dian)荷(he)為0.1C。涓流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)差(cha)異以及(ji)對(dui)更靈敏的(de)(de)(de)全電(dian)(dian)(dian)(dian)(dian)荷(he)檢測的(de)(de)(de)需(xu)求使得原(yuan)始鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiCd）充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)不適合鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiMH）電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiCd）充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)中(zhong)的(de)(de)(de)鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiMH）會(hui)過(guo)(guo)熱，但鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiMH）充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)中(zhong)的(de)(de)(de)鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（NiCd）運(yun)行(xing)良好(hao)。現代充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)適用(yong)于兩種電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)系統。

在0.1C至0.3C的C速率下，電壓和溫度曲線不具有觸發完全充電檢測的限定特性，并且充電器必須依賴于定時器。即使電池仍然冷卻，當對部分或完全充電的電池充電時，也會發生有害的過充電。如果電池容量損失并且只能保持一半電量，則會出現相同的情況。實質上，這個電池縮小到一半大小，而固定定時器被編程為應用100％充電而不考慮電池狀況。許多電池用戶抱怨使用壽命短于預期，故障可能在于充電器。低價的消費者充電器容易出錯。如果想使用低成本充電器來提高電池性能，請估算電池充電狀態并相應地設置充電時間。假定已滿時取出電池。如果充電器以高充電速率充電，就要注意進行溫度檢查。不冷不熱表明電池可能已滿。最好早點取出電池并在每次使用前充電，而不是將它們留在充電器中以備最終使用。

為鎳基電池充電的簡單指南

1、鎳基的(de)充電效率接(jie)近(jin)100％，最高可達70％。電池(chi)組保持涼爽，但開(kai)始升(sheng)溫，效率降低，充滿電。

2、鎳基電池必須在涓(juan)流充電時冷卻。如果溫(wen)暖(nuan)，涓(juan)流充電太(tai)高。

3、消費者充(chong)電器并不總(zong)是正確(que)終止充(chong)電。溫熱的時候取出電池(chi)。停(ting)止使用“烹(peng)飪”電池(chi)的充(chong)電器。

4、在室溫(wen)下(xia)充(chong)電。在高溫(wen)或冰點(dian)溫(wen)度下(xia)不要充(chong)電。鎳基(ji)電池最好快速充(chong)電; 持續緩慢的充(chong)電導致“ 記憶”。

5、鎳(nie)基和鋰(li)基電(dian)池(chi)(chi)需要不同的充電(dian)算法。鎳(nie)氫(qing)電(dian)池(chi)(chi)（NiMH）充電(dian)器也可以為(wei)鎳(nie)鎘電(dian)池(chi)(chi)（NiCd）充電(dian)， 鎳(nie)鎘電(dian)池(chi)(chi)（NiCd）充電(dian)器會過度充電(dian)鎳(nie)氫(qing)電(dian)池(chi)(chi)（NiMH）。

6、在充電器(qi)中放(fang)置鎳基電池超過幾天。如果可能，請在使(shi)用前(qian)取(qu)下包裝并進行短(duan)暫充電。
