一、電芯容額和額定容額分別是什么意思

1、電芯容額

電芯容(rong)額(e)是(shi)(shi)指(zhi)電(dian)(dian)(dian)池(chi)中實際儲存電(dian)(dian)(dian)能的(de)(de)容(rong)量。電(dian)(dian)(dian)芯(xin)(xin)是(shi)(shi)電(dian)(dian)(dian)池(chi)的(de)(de)核(he)心器件，電(dian)(dian)(dian)芯(xin)(xin)容(rong)額(e)是(shi)(shi)指(zhi)電(dian)(dian)(dian)芯(xin)(xin)所擁有的(de)(de)真(zhen)正(zheng)的(de)(de)儲存電(dian)(dian)(dian)能的(de)(de)容(rong)量。由(you)于電(dian)(dian)(dian)池(chi)本身也會存在(zai)一定(ding)的(de)(de)損耗，所以電(dian)(dian)(dian)池(chi)輸出(chu)的(de)(de)容(rong)量常(chang)常(chang)是(shi)(shi)小(xiao)于電(dian)(dian)(dian)芯(xin)(xin)容(rong)額(e)的(de)(de)。這(zhe)也是(shi)(shi)為什么在(zai)市場(chang)上(shang)比(bi)較靠譜的(de)(de)產品(pin)，會在(zai)包(bao)裝上(shang)標(biao)注上(shang)電(dian)(dian)(dian)芯(xin)(xin)容(rong)量，而不是(shi)(shi)單純(chun)的(de)(de)額(e)定(ding)容(rong)量。

2、額定容額

額定(ding)容額是指廠家為(wei)電(dian)(dian)池(chi)(chi)規定(ding)的(de)標準容量(liang)，也就(jiu)是電(dian)(dian)池(chi)(chi)的(de)正(zheng)常(chang)使用(yong)容量(liang)。在(zai)(zai)低功(gong)率使用(yong)下，電(dian)(dian)池(chi)(chi)可承(cheng)受最(zui)長(chang)的(de)時(shi)間。例如，一塊標有1500mAh的(de)AA電(dian)(dian)池(chi)(chi)，在(zai)(zai)正(zheng)常(chang)情況下，是可以提供1500毫安時(shi)的(de)電(dian)(dian)能，但在(zai)(zai)實際的(de)使用(yong)過程中，電(dian)(dian)池(chi)(chi)提供的(de)電(dian)(dian)能有可能會比額定(ding)容量(liang)少一些(xie)，這個因(yin)素涉及到(dao)電(dian)(dian)池(chi)(chi)內阻、放電(dian)(dian)倍(bei)率等復(fu)雜因(yin)素。

二、電芯容額和額定容額的區別

電芯容額往往小于額定容額。電池容額，又叫實際容額，一般指的是電池在放電的狀態下，它所具備的當前的實際容量。實際容量往往是會不斷變化的，比如在夏天氣溫較高時它的分子比較活躍，此時的電芯容額(e)較高(gao)，而(er)在冬(dong)天氣溫(wen)較低時活躍度不夠，容額(e)就會(hui)變低。

額定容(rong)額是(shi)電(dian)(dian)(dian)(dian)池上標(biao)注的(de)容(rong)量(liang)，比如我們使用的(de)手機(ji)所(suo)(suo)用的(de)鋰電(dian)(dian)(dian)(dian)池的(de)容(rong)量(liang)通常會(hui)有(you)一個額定值。在實(shi)(shi)際(ji)使用中(zhong)(zhong)，電(dian)(dian)(dian)(dian)池的(de)實(shi)(shi)際(ji)容(rong)量(liang)是(shi)要(yao)比額定容(rong)額低，原因就(jiu)是(shi)使用過程中(zhong)(zhong)很難(nan)達(da)到最(zui)理想(xiang)的(de)狀態，會(hui)導(dao)致實(shi)(shi)際(ji)容(rong)量(liang)往往達(da)不到額定容(rong)額。另外，電(dian)(dian)(dian)(dian)池額定容(rong)額是(shi)指標(biao)準所(suo)(suo)標(biao)稱電(dian)(dian)(dian)(dian)池的(de)容(rong)量(liang)值大(da)小(xiao)，而電(dian)(dian)(dian)(dian)芯容(rong)額是(shi)指電(dian)(dian)(dian)(dian)池在一定電(dian)(dian)(dian)(dian)流值放(fang)電(dian)(dian)(dian)(dian)時的(de)實(shi)(shi)際(ji)容(rong)量(liang)大(da)小(xiao)。
