充電電池評測分為自我評測與比較評測兩種參數體系。自我評測就是對一個品牌的充電電池評測(ce)(ce)(ce)自身部分性(xing)能，而(er)比較(jiao)評測(ce)(ce)(ce)則是對于兩(liang)種或(huo)者兩(liang)種以上品牌(pai)相同標稱(cheng)容量的電(dian)(dian)池就某一個性(xing)能參數進行的比較(jiao)。充電(dian)(dian)電(dian)(dian)池評測(ce)(ce)(ce)是描述電(dian)(dian)池客(ke)觀情況的重要手(shou)段，一般情況下，進行充電(dian)(dian)電(dian)(dian)池評測(ce)(ce)(ce)需(xu)要專門的檢(jian)(jian)測(ce)(ce)(ce)設備，故而(er)在實(shi)驗(yan)室檢(jian)(jian)驗(yan)為好(hao)，這樣可以縮小誤(wu)差。

　　無(wu)論是(shi)自我(wo)評(ping)(ping)測(ce)還是(shi)比較評(ping)(ping)測(ce)，充電(dian)(dian)電(dian)(dian)池評(ping)(ping)測(ce)都要有兩個前提(ti)條件，一是(shi)工作溫度在常溫范圍內，二是(shi)充電(dian)(dian)電(dian)(dian)池必須是(shi)新電(dian)(dian)。

　　對于充電電池評測中的自我評測，電池生產廠家的(de)(de)著重點往往并(bing)不完全(quan)相同：有的(de)(de)囊括所有性(xing)能參(can)數，有的(de)(de)則(ze)僅(jin)測試(shi)與容量相關的(de)(de)參(can)數，有的(de)(de)會在這個基礎上加上安全(quan)性(xing)能測試(shi)。

　　不過，對于比較評測，則基本上是圍繞著與容量相關的參數而進行。這時的前提條件，除了都是新電外，要注意所有設置條件的一致性，如溫度、電流、電壓、靜置時間、循(xun)環(huan)次數、檢(jian)測柜型號(hao)等(deng)所有充電(dian)電(dian)池評測的環(huan)境必須(xu)都是一樣的。

　　在比較評測(ce)中(zhong)，主要測(ce)試三個參數：

　　1、電池實(shi)(shi)際容量(liang)(liang)及其與(yu)標稱容量(liang)(liang)之差。評(ping)測實(shi)(shi)際容量(liang)(liang)以0.2C放電為準，在(zai)規定(ding)循環次數(shu)內，以每次記錄電量(liang)(liang)的加權平均值為實(shi)(shi)際容量(liang)(liang)，實(shi)(shi)際容量(liang)(liang)與(yu)標稱容量(liang)(liang)越(yue)接近，電池越(yue)“真”。

　　2、評測電(dian)池(chi)(chi)壽(shou)命(ming)。在電(dian)池(chi)(chi)實(shi)際(ji)(ji)容(rong)量(liang)(liang)評測的基礎上，將每款電(dian)池(chi)(chi)實(shi)際(ji)(ji)容(rong)量(liang)(liang)與標稱容(rong)量(liang)(liang)逐(zhu)次對(dui)比，得出各(ge)自的容(rong)量(liang)(liang)衰減率(lv)，從而(er)評測電(dian)池(chi)(chi)壽(shou)命(ming)。

　　3、評(ping)測(ce)自放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)：以(yi)(yi)一定時間(jian)為(wei)一個(ge)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)評(ping)測(ce)周(zhou)期，一直放(fang)到充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的截(jie)止電(dian)(dian)(dian)(dian)(dian)(dian)壓，看看其間(jian)的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容量變化。這(zhe)(zhe)個(ge)過程要注意(yi)：每一個(ge)品(pin)牌要選(xuan)取若干個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，因為(wei)這(zhe)(zhe)里有電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)均衡性問題。即使不同(tong)品(pin)牌的充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)總體(ti)自放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)評(ping)測(ce)結果中接近(jin)，一致性差的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也可(ke)以(yi)(yi)被(bei)認(ren)為(wei)長(chang)期保持電(dian)(dian)(dian)(dian)(dian)(dian)量能力差。

　　充電(dian)電(dian)池評測是(shi)一項嚴肅而科學的工作，工作人員(yuan)不但要記錄好(hao)充電(dian)電(dian)池評測的數(shu)據，而且要加強充電(dian)電(dian)池評測的數(shu)據處(chu)理和數(shu)字分析能力，從而更(geng)好(hao)地(di)為電(dian)池用戶提供精準服(fu)務。
