鎳氫電池規(gui)范叫法(fa)：金屬氫化物鎳電池

標稱電(dian)壓(ya)(表示(shi)電(dian)池電(dian)壓(ya)的近(jin)似值)：nX1.2V。(以3508氫電(dian)為(wei)例，n=3)

終止電壓(規定放電終止時)：nX1.0V。

充(chong)電(dian)制式：(恒流，在以0.2C放電(dian)至終止電(dian)壓(ya)后開始恒流充(chong)電(dian))

1、0.4C充(chong)電：以0.4C充(chong)電3.5h

2、完全(quan)充(chong)電：以0.1C充(chong)電16h

放電性能(neng)：(只說其一，與大家關(guan)系密切的)

0.2C放電：以0.2C放電至(zhi)終止電壓，放電時間應不小于5h。

國家技術(shu)監督部門(men)鑒定氫電(dian)(dian)(dian)(dian)(dian)容(rong)量，是按照(zhao)0.4C的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)制式充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，并按照(zhao)0.2C的放(fang)電(dian)(dian)(dian)(dian)(dian)制式放(fang)電(dian)(dian)(dian)(dian)(dian)的。完全充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)是用于(yu)鑒定電(dian)(dian)(dian)(dian)(dian)池的儲(chu)存性能的，在儲(chu)存12個月后(hou)，經完全充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)后(hou)，以0.2C放(fang)電(dian)(dian)(dian)(dian)(dian)，時間(jian)不(bu)應低于(yu)4h。過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)性能：0.4C充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)結束后(hou)，繼續以0.1C充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)48h，應不(bu)變形(xing)、不(bu)漏夜(ye)、不(bu)冒煙、等等。

以(yi)上是(shi)對氫電國家標準GB/T18288-2000的簡(jian)單描(miao)述，由此我們可以(yi)看出(chu)幾(ji)個(ge)問題：

1、對于氫電(dian)，完全充電(dian)有好(hao)處，可以充的(de)(de)更飽(bao)，好(hao)象就是(shi)大家的(de)(de)激(ji)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，要么(me)充電器充滿后已經(jing)截止(zhi)，剩(sheng)下是(shi)浪(lang)費時間，要么(me)充滿后的涓流過大造成過充。但氫電抗過充的能力(li)比鋰電強(qiang)的多。即使這(zhe)樣我們也不應該去考驗它(ta)呀。

3、10幾個小時的(de)(de)(de)充電(dian)(dian)時間概念是(shi)(shi)從氫電(dian)(dian)時延續(xu)來的(de)(de)(de)，但對于鋰電(dian)(dian)已經不(bu)適(shi)用了。氫電(dian)(dian)的(de)(de)(de)規范有(you)一(yi)個完全充電(dian)(dian)的(de)(de)(de)條(tiao)(tiao)款，但是(shi)(shi)有(you)條(tiao)(tiao)件的(de)(de)(de)。而鋰電(dian)(dian)根(gen)(gen)本沒(mei)(mei)有(you)相應的(de)(de)(de)條(tiao)(tiao)款，只不(bu)過(guo)在檢測前給一(yi)個預循(xun)環(huan)，而預循(xun)環(huan)充電(dian)(dian)恒流到4.2V即結束，根(gen)(gen)本沒(mei)(mei)有(you)后(hou)面的(de)(de)(de)橫壓補電(dian)(dian)過(guo)程(cheng)。鋰電(dian)(dian)不(bu)用所(suo)謂的(de)(de)(de)“激活”。電(dian)(dian)池(chi)生(sheng)產廠根(gen)(gen)本沒(mei)(mei)有(you)什么激活不(bu)激活的(de)(de)(de)過(guo)程(cheng)，生(sheng)產出的(de)(de)(de)電(dian)(dian)池(chi)都是(shi)(shi)活的(de)(de)(de)，只是(shi)(shi)氫電(dian)(dian)不(bu)適(shi)宜長(chang)時間儲(chu)存(cun)，時間長(chang)了會“死”，建議大(da)家氫電(dian)(dian)不(bu)用時，每三個月進行一(yi)個充放循(xun)環(huan)，并充滿(man)保存(cun)。保存(cun)溫度不(bu)能過(guo)高。(柜臺內(nei)被射燈照射很(hen)長(chang)時間的(de)(de)(de)不(bu)要買，儲(chu)存(cun)很(hen)長(chang)時間的(de)(de)(de)不(bu)要買)

4、氫(qing)(qing)(qing)電(dian)(dian)充(chong)(chong)飽后電(dian)(dian)壓是nX1.45V，以3508氫(qing)(qing)(qing)電(dian)(dian)為例是4.35V，市場上的品(pin)牌座(zuo)充(chong)(chong)，如果(guo)充(chong)(chong)氫(qing)(qing)(qing)電(dian)(dian)滿意，則絕對不(bu)能充(chong)(chong)鋰(li)電(dian)(dian)，如果(guo)充(chong)(chong)鋰(li)電(dian)(dian)滿意則充(chong)(chong)氫(qing)(qing)(qing)電(dian)(dian)不(bu)飽，但不(bu)會損壞。因為這種(zhong)座(zuo)充(chong)(chong)沒有判(pan)斷電(dian)(dian)池類(lei)型的能力，只是固定好了一個截(jie)止電(dian)(dian)壓。

5、所以(yi)，我們在市場(chang)上看到(dao)的(de)旅行(xing)充側(ce)面有一個氫電(dian)的(de)選擇(ze)開關(guan)，實際(ji)上就是切換(huan)截止(zhi)電(dian)壓(ya)的(de)。
