一、電芯容額和額定容額分別是什么意思

1、電芯容額

電芯容額(e)是指電(dian)(dian)池中實際儲存電(dian)(dian)能的(de)(de)容量(liang)。電(dian)(dian)芯(xin)是電(dian)(dian)池的(de)(de)核心(xin)器件(jian)，電(dian)(dian)芯(xin)容額(e)是指電(dian)(dian)芯(xin)所擁有的(de)(de)真正的(de)(de)儲存電(dian)(dian)能的(de)(de)容量(liang)。由于電(dian)(dian)池本(ben)身也(ye)會(hui)存在一定的(de)(de)損耗，所以(yi)電(dian)(dian)池輸(shu)出的(de)(de)容量(liang)常常是小于電(dian)(dian)芯(xin)容額(e)的(de)(de)。這(zhe)也(ye)是為(wei)什么在市場上(shang)(shang)比較靠譜(pu)的(de)(de)產品，會(hui)在包裝上(shang)(shang)標(biao)注(zhu)上(shang)(shang)電(dian)(dian)芯(xin)容量(liang)，而不是單純(chun)的(de)(de)額(e)定容量(liang)。

2、額定容額

額(e)定(ding)(ding)容(rong)(rong)額(e)是(shi)指廠家為電(dian)(dian)(dian)池(chi)規定(ding)(ding)的標準(zhun)容(rong)(rong)量，也就是(shi)電(dian)(dian)(dian)池(chi)的正(zheng)常使用容(rong)(rong)量。在(zai)(zai)低功率使用下，電(dian)(dian)(dian)池(chi)可(ke)承受(shou)最長(chang)的時(shi)間。例如，一(yi)(yi)塊標有(you)1500mAh的AA電(dian)(dian)(dian)池(chi)，在(zai)(zai)正(zheng)常情況下，是(shi)可(ke)以(yi)提供(gong)1500毫安(an)時(shi)的電(dian)(dian)(dian)能(neng)(neng)，但在(zai)(zai)實際的使用過(guo)程中，電(dian)(dian)(dian)池(chi)提供(gong)的電(dian)(dian)(dian)能(neng)(neng)有(you)可(ke)能(neng)(neng)會(hui)比(bi)額(e)定(ding)(ding)容(rong)(rong)量少一(yi)(yi)些，這個因素涉及到電(dian)(dian)(dian)池(chi)內(nei)阻、放(fang)電(dian)(dian)(dian)倍(bei)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)較高，而在(zai)冬天氣(qi)溫較低時活躍度不夠(gou)，容(rong)額(e)就會(hui)變低。

額定(ding)(ding)容(rong)(rong)額是(shi)電(dian)(dian)池(chi)上(shang)標注的(de)(de)容(rong)(rong)量(liang)，比如我們使(shi)用(yong)的(de)(de)手機所(suo)用(yong)的(de)(de)鋰電(dian)(dian)池(chi)的(de)(de)容(rong)(rong)量(liang)通常會有(you)一個額定(ding)(ding)值(zhi)(zhi)。在(zai)(zai)實際(ji)使(shi)用(yong)中(zhong)，電(dian)(dian)池(chi)的(de)(de)實際(ji)容(rong)(rong)量(liang)是(shi)要比額定(ding)(ding)容(rong)(rong)額低，原因就是(shi)使(shi)用(yong)過程中(zhong)很難(nan)達(da)到(dao)最理想的(de)(de)狀態，會導致實際(ji)容(rong)(rong)量(liang)往往達(da)不到(dao)額定(ding)(ding)容(rong)(rong)額。另外，電(dian)(dian)池(chi)額定(ding)(ding)容(rong)(rong)額是(shi)指標準所(suo)標稱(cheng)電(dian)(dian)池(chi)的(de)(de)容(rong)(rong)量(liang)值(zhi)(zhi)大小，而電(dian)(dian)芯容(rong)(rong)額是(shi)指電(dian)(dian)池(chi)在(zai)(zai)一定(ding)(ding)電(dian)(dian)流(liu)值(zhi)(zhi)放電(dian)(dian)時(shi)的(de)(de)實際(ji)容(rong)(rong)量(liang)大小。
