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(e)是(shi)(shi)指(zhi)電(dian)(dian)池(chi)中實(shi)際儲存(cun)電(dian)(dian)能(neng)的(de)(de)(de)(de)(de)(de)容(rong)(rong)量(liang)。電(dian)(dian)芯(xin)是(shi)(shi)電(dian)(dian)池(chi)的(de)(de)(de)(de)(de)(de)核心器件，電(dian)(dian)芯(xin)容(rong)(rong)額(e)是(shi)(shi)指(zhi)電(dian)(dian)芯(xin)所擁有的(de)(de)(de)(de)(de)(de)真正的(de)(de)(de)(de)(de)(de)儲存(cun)電(dian)(dian)能(neng)的(de)(de)(de)(de)(de)(de)容(rong)(rong)量(liang)。由于(yu)電(dian)(dian)池(chi)本身也(ye)會(hui)存(cun)在(zai)(zai)(zai)一定(ding)(ding)的(de)(de)(de)(de)(de)(de)損耗，所以電(dian)(dian)池(chi)輸出的(de)(de)(de)(de)(de)(de)容(rong)(rong)量(liang)常常是(shi)(shi)小于(yu)電(dian)(dian)芯(xin)容(rong)(rong)額(e)的(de)(de)(de)(de)(de)(de)。這也(ye)是(shi)(shi)為什么在(zai)(zai)(zai)市(shi)場(chang)上比較靠(kao)譜的(de)(de)(de)(de)(de)(de)產品，會(hui)在(zai)(zai)(zai)包裝上標注上電(dian)(dian)芯(xin)容(rong)(rong)量(liang)，而不(bu)是(shi)(shi)單純的(de)(de)(de)(de)(de)(de)額(e)定(ding)(ding)容(rong)(rong)量(liang)。

2、額定容額

額(e)定容(rong)(rong)額(e)是指(zhi)廠家為電(dian)(dian)池(chi)規定的(de)標準容(rong)(rong)量，也就是電(dian)(dian)池(chi)的(de)正常使(shi)用容(rong)(rong)量。在低功率使(shi)用下，電(dian)(dian)池(chi)可承受最長的(de)時間。例如(ru)，一塊標有(you)1500mAh的(de)AA電(dian)(dian)池(chi)，在正常情況下，是可以提供(gong)1500毫安時的(de)電(dian)(dian)能，但在實(shi)際的(de)使(shi)用過(guo)程中，電(dian)(dian)池(chi)提供(gong)的(de)電(dian)(dian)能有(you)可能會比額(e)定容(rong)(rong)量少一些，這個(ge)因(yin)素(su)涉及到電(dian)(dian)池(chi)內阻、放電(dian)(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，此時的電芯容額較(jiao)高(gao)，而在冬天氣溫較(jiao)低時活躍度不夠(gou)，容額就會變(bian)低。

額(e)(e)(e)(e)定容(rong)(rong)額(e)(e)(e)(e)是電(dian)(dian)(dian)(dian)(dian)(dian)池上標(biao)注的(de)(de)容(rong)(rong)量(liang)，比如我們(men)使(shi)用(yong)(yong)的(de)(de)手(shou)機所用(yong)(yong)的(de)(de)鋰電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)容(rong)(rong)量(liang)通常會(hui)有一個額(e)(e)(e)(e)定值(zhi)。在實(shi)(shi)際(ji)使(shi)用(yong)(yong)中(zhong)，電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)實(shi)(shi)際(ji)容(rong)(rong)量(liang)是要比額(e)(e)(e)(e)定容(rong)(rong)額(e)(e)(e)(e)低，原因就是使(shi)用(yong)(yong)過程中(zhong)很難(nan)達到(dao)最理想(xiang)的(de)(de)狀(zhuang)態，會(hui)導致實(shi)(shi)際(ji)容(rong)(rong)量(liang)往往達不到(dao)額(e)(e)(e)(e)定容(rong)(rong)額(e)(e)(e)(e)。另外(wai)，電(dian)(dian)(dian)(dian)(dian)(dian)池額(e)(e)(e)(e)定容(rong)(rong)額(e)(e)(e)(e)是指標(biao)準所標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)容(rong)(rong)量(liang)值(zhi)大(da)小，而電(dian)(dian)(dian)(dian)(dian)(dian)芯(xin)容(rong)(rong)額(e)(e)(e)(e)是指電(dian)(dian)(dian)(dian)(dian)(dian)池在一定電(dian)(dian)(dian)(dian)(dian)(dian)流值(zhi)放電(dian)(dian)(dian)(dian)(dian)(dian)時的(de)(de)實(shi)(shi)際(ji)容(rong)(rong)量(liang)大(da)小。
