鎳(nie)氫(qing)電(dian)池規范(fan)叫法(fa)：金屬氫(qing)化物(wu)鎳(nie)電(dian)池

標稱電壓(表(biao)示電池電壓的近似值(zhi))：nX1.2V。(以3508氫電為(wei)例，n=3)

終止電壓(規(gui)定放電終止時)：nX1.0V。

充電(dian)(dian)制式(shi)：(恒(heng)流，在以(yi)0.2C放電(dian)(dian)至終(zhong)止電(dian)(dian)壓后開始恒(heng)流充電(dian)(dian))

1、0.4C充電(dian)：以0.4C充電(dian)3.5h

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

放(fang)電性能(neng)：(只說其一，與大(da)家關(guan)系密切的)

0.2C放電：以0.2C放電至終止電壓，放電時間應(ying)不小于5h。

國家(jia)技術監督部門(men)鑒定氫電(dian)(dian)(dian)容(rong)量，是按照(zhao)0.4C的(de)充電(dian)(dian)(dian)制(zhi)式充電(dian)(dian)(dian)，并按照(zhao)0.2C的(de)放(fang)電(dian)(dian)(dian)制(zhi)式放(fang)電(dian)(dian)(dian)的(de)。完全充電(dian)(dian)(dian)是用于鑒定電(dian)(dian)(dian)池的(de)儲存性(xing)能的(de)，在(zai)儲存12個(ge)月后，經完全充電(dian)(dian)(dian)后，以0.2C放(fang)電(dian)(dian)(dian)，時間(jian)不(bu)應低于4h。過充電(dian)(dian)(dian)性(xing)能：0.4C充電(dian)(dian)(dian)結束(shu)后，繼續以0.1C充電(dian)(dian)(dian)48h，應不(bu)變形、不(bu)漏夜、不(bu)冒煙(yan)、等等。

以上(shang)是對(dui)氫電(dian)國家標準GB/T18288-2000的簡單描述，由此我(wo)們可以看(kan)出(chu)幾個問題：

1、對于氫電，完(wan)全充電有好處，可以(yi)充的更飽(bao)，好象就是大家的激活(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(xiao)時(shi)(shi)，要么(me)充電(dian)(dian)器充滿后已經截止，剩(sheng)下(xia)是(shi)浪費時(shi)(shi)間(jian)，要么(me)充滿后的(de)涓流過大造成(cheng)過充。但氫電(dian)(dian)抗(kang)過充的(de)能力比鋰(li)電(dian)(dian)強的(de)多。即(ji)使這樣我(wo)們也(ye)不(bu)應(ying)該去考驗它(ta)呀。

3、10幾個(ge)小(xiao)時(shi)(shi)(shi)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間(jian)(jian)概念是(shi)從氫(qing)(qing)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)延(yan)續來的(de)(de)(de)(de)，但對于鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)已經不(bu)(bu)適用(yong)了。氫(qing)(qing)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)規范(fan)有(you)(you)一個(ge)完全(quan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)條款，但是(shi)有(you)(you)條件的(de)(de)(de)(de)。而(er)鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)根(gen)本沒有(you)(you)相應的(de)(de)(de)(de)條款，只不(bu)(bu)過(guo)在檢測(ce)前(qian)給一個(ge)預(yu)循(xun)環(huan)(huan)，而(er)預(yu)循(xun)環(huan)(huan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)恒流(liu)到4.2V即(ji)結束，根(gen)本沒有(you)(you)后面(mian)的(de)(de)(de)(de)橫(heng)壓補(bu)電(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)。鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)用(yong)所謂的(de)(de)(de)(de)“激(ji)活(huo)(huo)”。電(dian)(dian)(dian)(dian)(dian)池(chi)生產(chan)廠根(gen)本沒有(you)(you)什(shen)么(me)激(ji)活(huo)(huo)不(bu)(bu)激(ji)活(huo)(huo)的(de)(de)(de)(de)過(guo)程(cheng)，生產(chan)出(chu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)都是(shi)活(huo)(huo)的(de)(de)(de)(de)，只是(shi)氫(qing)(qing)電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)適宜長時(shi)(shi)(shi)間(jian)(jian)儲存(cun)，時(shi)(shi)(shi)間(jian)(jian)長了會“死”，建議大(da)家氫(qing)(qing)電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)用(yong)時(shi)(shi)(shi)，每三(san)個(ge)月進(jin)行一個(ge)充(chong)(chong)(chong)放循(xun)環(huan)(huan)，并充(chong)(chong)(chong)滿保存(cun)。保存(cun)溫度不(bu)(bu)能過(guo)高。(柜臺內被射(she)燈照射(she)很長時(shi)(shi)(shi)間(jian)(jian)的(de)(de)(de)(de)不(bu)(bu)要買，儲存(cun)很長時(shi)(shi)(shi)間(jian)(jian)的(de)(de)(de)(de)不(bu)(bu)要買)

4、氫(qing)電(dian)充(chong)(chong)(chong)飽(bao)后電(dian)壓是nX1.45V，以3508氫(qing)電(dian)為例是4.35V，市場上的品牌座充(chong)(chong)(chong)，如(ru)果(guo)充(chong)(chong)(chong)氫(qing)電(dian)滿意，則(ze)絕對(dui)不能充(chong)(chong)(chong)鋰(li)電(dian)，如(ru)果(guo)充(chong)(chong)(chong)鋰(li)電(dian)滿意則(ze)充(chong)(chong)(chong)氫(qing)電(dian)不飽(bao)，但不會(hui)損壞。因為這(zhe)種座充(chong)(chong)(chong)沒有判斷電(dian)池(chi)類(lei)型的能力，只(zhi)是固(gu)定好了一個截止電(dian)壓。

5、所以，我們在市(shi)場上(shang)看到的旅行充側面有(you)一個氫電的選擇開關，實際上(shang)就是切換截止電壓的。
