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)(e)(e)是指(zhi)電(dian)(dian)(dian)(dian)池中實際(ji)儲存(cun)電(dian)(dian)(dian)(dian)能的容量(liang)(liang)。電(dian)(dian)(dian)(dian)芯(xin)是電(dian)(dian)(dian)(dian)池的核心(xin)器(qi)件(jian)，電(dian)(dian)(dian)(dian)芯(xin)容額(e)(e)(e)是指(zhi)電(dian)(dian)(dian)(dian)芯(xin)所(suo)擁有的真正的儲存(cun)電(dian)(dian)(dian)(dian)能的容量(liang)(liang)。由于(yu)電(dian)(dian)(dian)(dian)池本(ben)身也會存(cun)在(zai)(zai)一(yi)定的損耗，所(suo)以電(dian)(dian)(dian)(dian)池輸出的容量(liang)(liang)常常是小于(yu)電(dian)(dian)(dian)(dian)芯(xin)容額(e)(e)(e)的。這也是為(wei)什么在(zai)(zai)市場(chang)上(shang)(shang)比(bi)較靠譜(pu)的產品，會在(zai)(zai)包裝上(shang)(shang)標注上(shang)(shang)電(dian)(dian)(dian)(dian)芯(xin)容量(liang)(liang)，而(er)不(bu)是單純的額(e)(e)(e)定容量(liang)(liang)。

2、額定容額

額定(ding)容額是指廠家為電(dian)池規(gui)定(ding)的標(biao)準(zhun)容量(liang)(liang)(liang)，也就是電(dian)池的正(zheng)常使(shi)用(yong)容量(liang)(liang)(liang)。在低(di)功(gong)率(lv)使(shi)用(yong)下，電(dian)池可承受最(zui)長(chang)的時間。例如，一塊標(biao)有1500mAh的AA電(dian)池，在正(zheng)常情(qing)況下，是可以提供(gong)1500毫安(an)時的電(dian)能，但(dan)在實際的使(shi)用(yong)過程中(zhong)，電(dian)池提供(gong)的電(dian)能有可能會比額定(ding)容量(liang)(liang)(liang)少一些，這個(ge)因(yin)素(su)(su)涉及到電(dian)池內阻、放(fang)電(dian)倍率(lv)等復雜因(yin)素(su)(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)(rong)額較(jiao)高(gao)，而(er)在冬天氣溫(wen)較(jiao)低時(shi)活躍度不夠，容(rong)(rong)額就會變低。

額(e)(e)定(ding)容(rong)(rong)額(e)(e)是電(dian)(dian)池(chi)上標注的容(rong)(rong)量(liang)(liang)，比(bi)如(ru)我(wo)們使(shi)用(yong)的手機(ji)所用(yong)的鋰電(dian)(dian)池(chi)的容(rong)(rong)量(liang)(liang)通常會(hui)有一個額(e)(e)定(ding)值(zhi)(zhi)。在(zai)實(shi)(shi)(shi)際(ji)使(shi)用(yong)中，電(dian)(dian)池(chi)的實(shi)(shi)(shi)際(ji)容(rong)(rong)量(liang)(liang)是要(yao)比(bi)額(e)(e)定(ding)容(rong)(rong)額(e)(e)低，原因就是使(shi)用(yong)過程(cheng)中很(hen)難達到(dao)最理想的狀態，會(hui)導致實(shi)(shi)(shi)際(ji)容(rong)(rong)量(liang)(liang)往(wang)往(wang)達不(bu)到(dao)額(e)(e)定(ding)容(rong)(rong)額(e)(e)。另(ling)外，電(dian)(dian)池(chi)額(e)(e)定(ding)容(rong)(rong)額(e)(e)是指標準所標稱電(dian)(dian)池(chi)的容(rong)(rong)量(liang)(liang)值(zhi)(zhi)大小(xiao)，而(er)電(dian)(dian)芯容(rong)(rong)額(e)(e)是指電(dian)(dian)池(chi)在(zai)一定(ding)電(dian)(dian)流值(zhi)(zhi)放(fang)電(dian)(dian)時的實(shi)(shi)(shi)際(ji)容(rong)(rong)量(liang)(liang)大小(xiao)。
