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)指電(dian)(dian)(dian)池(chi)中(zhong)實(shi)際儲存電(dian)(dian)(dian)能的(de)(de)(de)容(rong)量。電(dian)(dian)(dian)芯(xin)(xin)(xin)(xin)是(shi)電(dian)(dian)(dian)池(chi)的(de)(de)(de)核心器件，電(dian)(dian)(dian)芯(xin)(xin)(xin)(xin)容(rong)額(e)是(shi)指電(dian)(dian)(dian)芯(xin)(xin)(xin)(xin)所(suo)擁有(you)的(de)(de)(de)真(zhen)正的(de)(de)(de)儲存電(dian)(dian)(dian)能的(de)(de)(de)容(rong)量。由于(yu)(yu)電(dian)(dian)(dian)池(chi)本(ben)身(shen)也會存在(zai)一定的(de)(de)(de)損(sun)耗，所(suo)以電(dian)(dian)(dian)池(chi)輸出的(de)(de)(de)容(rong)量常常是(shi)小于(yu)(yu)電(dian)(dian)(dian)芯(xin)(xin)(xin)(xin)容(rong)額(e)的(de)(de)(de)。這也是(shi)為什么在(zai)市場上(shang)比(bi)較靠譜(pu)的(de)(de)(de)產品，會在(zai)包(bao)裝上(shang)標注上(shang)電(dian)(dian)(dian)芯(xin)(xin)(xin)(xin)容(rong)量，而不是(shi)單純(chun)的(de)(de)(de)額(e)定容(rong)量。

2、額定容額

額(e)定容(rong)額(e)是指廠家為電(dian)池(chi)(chi)規(gui)定的(de)標準容(rong)量(liang)，也(ye)就是電(dian)池(chi)(chi)的(de)正(zheng)常(chang)使(shi)(shi)用容(rong)量(liang)。在(zai)低功率使(shi)(shi)用下，電(dian)池(chi)(chi)可承(cheng)受最(zui)長(chang)的(de)時(shi)間。例如，一(yi)塊標有(you)1500mAh的(de)AA電(dian)池(chi)(chi)，在(zai)正(zheng)常(chang)情況下，是可以提(ti)供(gong)1500毫安時(shi)的(de)電(dian)能(neng)(neng)，但在(zai)實(shi)際的(de)使(shi)(shi)用過程中，電(dian)池(chi)(chi)提(ti)供(gong)的(de)電(dian)能(neng)(neng)有(you)可能(neng)(neng)會比額(e)定容(rong)量(liang)少一(yi)些，這個因(yin)素(su)涉及到電(dian)池(chi)(chi)內阻、放電(dian)倍率等復雜因(yin)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(e)較(jiao)高，而在冬天(tian)氣溫(wen)較(jiao)低時活(huo)躍度不(bu)夠，容(rong)額(e)就會(hui)變(bian)低。

額(e)(e)定(ding)容(rong)額(e)(e)是電(dian)(dian)(dian)池(chi)上標(biao)注(zhu)的(de)(de)容(rong)量(liang)(liang)，比如我們(men)使(shi)用(yong)的(de)(de)手(shou)機所用(yong)的(de)(de)鋰電(dian)(dian)(dian)池(chi)的(de)(de)容(rong)量(liang)(liang)通(tong)常(chang)會有一個額(e)(e)定(ding)值(zhi)。在實(shi)(shi)際使(shi)用(yong)中，電(dian)(dian)(dian)池(chi)的(de)(de)實(shi)(shi)際容(rong)量(liang)(liang)是要比額(e)(e)定(ding)容(rong)額(e)(e)低(di)，原因(yin)就是使(shi)用(yong)過程中很難達到最理想的(de)(de)狀(zhuang)態，會導(dao)致實(shi)(shi)際容(rong)量(liang)(liang)往(wang)往(wang)達不(bu)到額(e)(e)定(ding)容(rong)額(e)(e)。另外，電(dian)(dian)(dian)池(chi)額(e)(e)定(ding)容(rong)額(e)(e)是指(zhi)標(biao)準所標(biao)稱(cheng)電(dian)(dian)(dian)池(chi)的(de)(de)容(rong)量(liang)(liang)值(zhi)大小，而(er)電(dian)(dian)(dian)芯容(rong)額(e)(e)是指(zhi)電(dian)(dian)(dian)池(chi)在一定(ding)電(dian)(dian)(dian)流(liu)值(zhi)放(fang)電(dian)(dian)(dian)時的(de)(de)實(shi)(shi)際容(rong)量(liang)(liang)大小。
