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)指(zhi)電(dian)(dian)池中實際儲存電(dian)(dian)能的(de)(de)容(rong)量(liang)。電(dian)(dian)芯(xin)是(shi)電(dian)(dian)池的(de)(de)核(he)心器件，電(dian)(dian)芯(xin)容(rong)額(e)是(shi)指(zhi)電(dian)(dian)芯(xin)所(suo)擁(yong)有的(de)(de)真正的(de)(de)儲存電(dian)(dian)能的(de)(de)容(rong)量(liang)。由于(yu)電(dian)(dian)池本身也(ye)會(hui)存在(zai)一定的(de)(de)損耗(hao)，所(suo)以電(dian)(dian)池輸出的(de)(de)容(rong)量(liang)常(chang)常(chang)是(shi)小(xiao)于(yu)電(dian)(dian)芯(xin)容(rong)額(e)的(de)(de)。這也(ye)是(shi)為什么(me)在(zai)市(shi)場上比較靠譜(pu)的(de)(de)產品，會(hui)在(zai)包裝上標注(zhu)上電(dian)(dian)芯(xin)容(rong)量(liang)，而不是(shi)單純(chun)的(de)(de)額(e)定容(rong)量(liang)。

2、額定容額

額(e)定(ding)容(rong)(rong)額(e)是(shi)(shi)指廠家(jia)為電(dian)(dian)池(chi)(chi)規定(ding)的標準(zhun)容(rong)(rong)量(liang)，也就(jiu)是(shi)(shi)電(dian)(dian)池(chi)(chi)的正常(chang)使用容(rong)(rong)量(liang)。在(zai)低功率使用下，電(dian)(dian)池(chi)(chi)可(ke)承受最長的時間。例如，一(yi)塊(kuai)標有(you)1500mAh的AA電(dian)(dian)池(chi)(chi)，在(zai)正常(chang)情況下，是(shi)(shi)可(ke)以提供1500毫(hao)安時的電(dian)(dian)能(neng)，但(dan)在(zai)實際的使用過程中，電(dian)(dian)池(chi)(chi)提供的電(dian)(dian)能(neng)有(you)可(ke)能(neng)會比(bi)額(e)定(ding)容(rong)(rong)量(liang)少(shao)一(yi)些(xie)，這個因素(su)涉及到電(dian)(dian)池(chi)(chi)內阻、放電(dian)(dian)倍率等復(fu)雜因素(su)。

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(rong)額較高，而在冬(dong)天氣溫(wen)較低時活躍度(du)不夠，容(rong)額就(jiu)會變低。

額(e)(e)(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)(e)(e)是電(dian)(dian)(dian)池(chi)上標注的容(rong)(rong)(rong)(rong)量(liang)(liang)，比(bi)如我(wo)們使(shi)(shi)用的手機所用的鋰電(dian)(dian)(dian)池(chi)的容(rong)(rong)(rong)(rong)量(liang)(liang)通常(chang)會有一個額(e)(e)(e)(e)(e)定(ding)(ding)值。在(zai)實(shi)際(ji)(ji)使(shi)(shi)用中，電(dian)(dian)(dian)池(chi)的實(shi)際(ji)(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)是要比(bi)額(e)(e)(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)(e)(e)低，原因就是使(shi)(shi)用過程中很難達(da)到最理想的狀態，會導致實(shi)際(ji)(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)往(wang)往(wang)達(da)不(bu)到額(e)(e)(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)(e)(e)。另外，電(dian)(dian)(dian)池(chi)額(e)(e)(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)(e)(e)是指標準所標稱電(dian)(dian)(dian)池(chi)的容(rong)(rong)(rong)(rong)量(liang)(liang)值大小，而電(dian)(dian)(dian)芯容(rong)(rong)(rong)(rong)額(e)(e)(e)(e)(e)是指電(dian)(dian)(dian)池(chi)在(zai)一定(ding)(ding)電(dian)(dian)(dian)流值放電(dian)(dian)(dian)時的實(shi)際(ji)(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)大小。
