鎳(nie)氫(qing)電池規(gui)范叫(jiao)法：金屬(shu)氫(qing)化物鎳(nie)電池

標(biao)稱(cheng)電(dian)壓(ya)(ya)(表示電(dian)池電(dian)壓(ya)(ya)的近(jin)似值)：nX1.2V。(以3508氫電(dian)為例(li)，n=3)

終止電(dian)壓(規定放(fang)電(dian)終止時(shi))：nX1.0V。

充(chong)電(dian)(dian)制式(shi)：(恒流，在以0.2C放電(dian)(dian)至(zhi)終止電(dian)(dian)壓后(hou)開(kai)始恒流充(chong)電(dian)(dian))

1、0.4C充(chong)電：以(yi)0.4C充(chong)電3.5h

2、完(wan)全(quan)充電(dian)：以0.1C充電(dian)16h

放電性能：(只說其一，與大家關系密切(qie)的)

0.2C放(fang)電(dian)：以0.2C放(fang)電(dian)至終止電(dian)壓，放(fang)電(dian)時間應不小(xiao)于5h。

國(guo)家技術監督部門(men)鑒定氫電(dian)(dian)(dian)容量(liang)，是(shi)按(an)照0.4C的充(chong)電(dian)(dian)(dian)制式充(chong)電(dian)(dian)(dian)，并按(an)照0.2C的放(fang)電(dian)(dian)(dian)制式放(fang)電(dian)(dian)(dian)的。完全(quan)充(chong)電(dian)(dian)(dian)是(shi)用于(yu)鑒定電(dian)(dian)(dian)池的儲存(cun)性能的，在儲存(cun)12個(ge)月后，經完全(quan)充(chong)電(dian)(dian)(dian)后，以(yi)0.2C放(fang)電(dian)(dian)(dian)，時間不(bu)(bu)應低于(yu)4h。過充(chong)電(dian)(dian)(dian)性能：0.4C充(chong)電(dian)(dian)(dian)結束(shu)后，繼續以(yi)0.1C充(chong)電(dian)(dian)(dian)48h，應不(bu)(bu)變(bian)形、不(bu)(bu)漏夜、不(bu)(bu)冒煙、等等。

以(yi)上是(shi)對氫(qing)電國家標準GB/T18288-2000的簡單描述，由此我們可以(yi)看(kan)出幾個問題(ti)：

1、對(dui)于氫電(dian)，完全充(chong)電(dian)有好處，可以充(chong)的(de)更(geng)飽，好象(xiang)就是大家的(de)激活(huo)概念。

2、但是，完全充電是有條件的，那就是0.1C，但市場上的充電器不會設計這么小的充電電流(以3508氫電計，應是50mA)，如果用普通的充電器16小時(shi)，要(yao)么充(chong)(chong)電(dian)器充(chong)(chong)滿(man)后已經(jing)截止(zhi)，剩下是(shi)浪(lang)費時(shi)間，要(yao)么充(chong)(chong)滿(man)后的涓流(liu)過(guo)大造成過(guo)充(chong)(chong)。但氫電(dian)抗過(guo)充(chong)(chong)的能(neng)力比鋰(li)電(dian)強的多。即使(shi)這樣我們也不應(ying)該去考驗它呀。

3、10幾個小時的(de)充(chong)(chong)電(dian)(dian)(dian)時間(jian)概念是從氫(qing)電(dian)(dian)(dian)時延續來的(de)，但對于鋰電(dian)(dian)(dian)已經不(bu)適(shi)用了。氫(qing)電(dian)(dian)(dian)的(de)規(gui)范有(you)(you)(you)一個完全(quan)充(chong)(chong)電(dian)(dian)(dian)的(de)條款(kuan)，但是有(you)(you)(you)條件(jian)的(de)。而鋰電(dian)(dian)(dian)根本(ben)(ben)沒(mei)有(you)(you)(you)相應的(de)條款(kuan)，只不(bu)過在檢(jian)測前給一個預循環(huan)，而預循環(huan)充(chong)(chong)電(dian)(dian)(dian)恒流(liu)到4.2V即結束，根本(ben)(ben)沒(mei)有(you)(you)(you)后(hou)面(mian)的(de)橫壓補電(dian)(dian)(dian)過程。鋰電(dian)(dian)(dian)不(bu)用所謂的(de)“激(ji)活”。電(dian)(dian)(dian)池(chi)生產廠根本(ben)(ben)沒(mei)有(you)(you)(you)什么激(ji)活不(bu)激(ji)活的(de)過程，生產出的(de)電(dian)(dian)(dian)池(chi)都是活的(de)，只是氫(qing)電(dian)(dian)(dian)不(bu)適(shi)宜(yi)長時間(jian)儲存，時間(jian)長了會“死”，建議(yi)大家氫(qing)電(dian)(dian)(dian)不(bu)用時，每三個月(yue)進行一個充(chong)(chong)放循環(huan)，并充(chong)(chong)滿保存。保存溫度不(bu)能(neng)過高(gao)。(柜臺內被射燈照射很長時間(jian)的(de)不(bu)要買，儲存很長時間(jian)的(de)不(bu)要買)

4、氫(qing)(qing)電(dian)充(chong)飽后(hou)電(dian)壓是nX1.45V，以3508氫(qing)(qing)電(dian)為(wei)例是4.35V，市場上的品牌座充(chong)，如果充(chong)氫(qing)(qing)電(dian)滿意，則絕(jue)對不能充(chong)鋰電(dian)，如果充(chong)鋰電(dian)滿意則充(chong)氫(qing)(qing)電(dian)不飽，但不會損(sun)壞(huai)。因為(wei)這種座充(chong)沒(mei)有判斷電(dian)池類型(xing)的能力，只是固(gu)定好了一個截止(zhi)電(dian)壓。

5、所(suo)以，我們在市場(chang)上(shang)看到的旅行(xing)充側面有一個氫電的選擇開關，實際(ji)上(shang)就是切換截(jie)止電壓(ya)的。
