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)(rong)額是(shi)指(zhi)電(dian)池(chi)中(zhong)實際儲存(cun)電(dian)能(neng)的(de)容(rong)(rong)量(liang)。電(dian)芯(xin)是(shi)電(dian)池(chi)的(de)核心器件，電(dian)芯(xin)容(rong)(rong)額是(shi)指(zhi)電(dian)芯(xin)所擁有的(de)真正的(de)儲存(cun)電(dian)能(neng)的(de)容(rong)(rong)量(liang)。由于(yu)電(dian)池(chi)本身(shen)也(ye)會存(cun)在(zai)一(yi)定的(de)損耗，所以電(dian)池(chi)輸出的(de)容(rong)(rong)量(liang)常(chang)常(chang)是(shi)小于(yu)電(dian)芯(xin)容(rong)(rong)額的(de)。這也(ye)是(shi)為什么在(zai)市(shi)場上比較靠譜(pu)的(de)產品，會在(zai)包裝(zhuang)上標注上電(dian)芯(xin)容(rong)(rong)量(liang)，而(er)不是(shi)單純的(de)額定容(rong)(rong)量(liang)。

2、額定容額

額定(ding)容(rong)額是(shi)指廠家為電(dian)池(chi)規定(ding)的(de)(de)標準容(rong)量，也就(jiu)是(shi)電(dian)池(chi)的(de)(de)正(zheng)常(chang)使用容(rong)量。在低功率使用下，電(dian)池(chi)可承受(shou)最長的(de)(de)時間。例(li)如，一塊標有(you)1500mAh的(de)(de)AA電(dian)池(chi)，在正(zheng)常(chang)情況(kuang)下，是(shi)可以提(ti)供1500毫(hao)安(an)時的(de)(de)電(dian)能，但(dan)在實(shi)際的(de)(de)使用過程中，電(dian)池(chi)提(ti)供的(de)(de)電(dian)能有(you)可能會比額定(ding)容(rong)量少一些，這(zhe)個(ge)因素涉及到電(dian)池(chi)內阻、放電(dian)倍率等(deng)復雜因素。

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(rong)額(e)較(jiao)高，而(er)在冬天(tian)氣(qi)溫較(jiao)低時活躍度不夠(gou)，容(rong)額(e)就會變低。

額(e)定(ding)(ding)(ding)容(rong)(rong)(rong)(rong)額(e)是電(dian)(dian)池上標注(zhu)的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)，比如我們使(shi)用(yong)(yong)的(de)手機所用(yong)(yong)的(de)鋰(li)電(dian)(dian)池的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)通常會(hui)有一個額(e)定(ding)(ding)(ding)值(zhi)。在實(shi)際(ji)使(shi)用(yong)(yong)中，電(dian)(dian)池的(de)實(shi)際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)是要(yao)比額(e)定(ding)(ding)(ding)容(rong)(rong)(rong)(rong)額(e)低，原(yuan)因就是使(shi)用(yong)(yong)過(guo)程中很(hen)難(nan)達到(dao)最理想的(de)狀態，會(hui)導致實(shi)際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)往(wang)往(wang)達不(bu)到(dao)額(e)定(ding)(ding)(ding)容(rong)(rong)(rong)(rong)額(e)。另外，電(dian)(dian)池額(e)定(ding)(ding)(ding)容(rong)(rong)(rong)(rong)額(e)是指(zhi)標準所標稱(cheng)電(dian)(dian)池的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)值(zhi)大小，而電(dian)(dian)芯容(rong)(rong)(rong)(rong)額(e)是指(zhi)電(dian)(dian)池在一定(ding)(ding)(ding)電(dian)(dian)流值(zhi)放電(dian)(dian)時的(de)實(shi)際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)大小。
