電動自(zi)行車鉛酸電池指標(biao)有以下(xia)4個方面：
1、電池額定容量
是按國家標準規定的(de)電(dian)池(chi)容量(liang)。單位用Ah即安時來表示，它反映(ying)了電(dian)池(chi)存(cun)儲(chu)電(dian)量(liang)的(de)大(da)小(xiao)。數值越大(da)，則存(cun)儲(chu)的(de)電(dian)量(liang)就越多(duo)，現在市場上的(de)電(dian)動車蓄電(dian)池(chi)的(de)容量(liang)一般都是10Ah，以(yi)恒流5A放電(dian)120分鐘。
2、電池的實際容量
反映電(dian)(dian)池(chi)實(shi)際(ji)(ji)存儲電(dian)(dian)量(liang)的(de)大(da)小，單(dan)位用(yong)Ah安時(shi)表示(shi)。同樣安時(shi)越大(da)，則電(dian)(dian)池(chi)容(rong)量(liang)就越大(da)，電(dian)(dian)動(dong)車(che)(che)的(de)續行(xing)里程就越遠。在(zai)(zai)(zai)使(shi)用(yong)過程中，電(dian)(dian)池(chi)的(de)實(shi)際(ji)(ji)容(rong)量(liang)會(hui)逐(zhu)步衰(shuai)減。國家標準規定(ding)(ding)新出廠的(de)電(dian)(dian)池(chi)實(shi)際(ji)(ji)容(rong)量(liang)大(da)于(yu)額(e)定(ding)(ding)容(rong)量(liang)值為合格電(dian)(dian)池(chi)。如現在(zai)(zai)(zai)市場上電(dian)(dian)動(dong)自(zi)行(xing)車(che)(che)的(de)電(dian)(dian)池(chi)，以恒電(dian)(dian)流5A放電(dian)(dian)要超(chao)過2小時(shi)（120分鐘），大(da)于(yu)（2小時(shi)×5A）10Ah。相(xiang)當于(yu)電(dian)(dian)動(dong)車(che)(che)在(zai)(zai)(zai)平坦的(de)路上連續行(xing)駛2小時(shi)以上。
3、放電循環壽命
指的(de)是電(dian)(dian)池(chi)(chi)進(jin)行(xing)(xing)(xing)充電(dian)(dian)、放(fang)電(dian)(dian)直到電(dian)(dian)池(chi)(chi)容(rong)量減少到額(e)定容(rong)量70％時(shi)的(de)循環(huan)(huan)次(ci)數(shu)，充足電(dian)(dian)后再放(fang)電(dian)(dian)到一(yi)定的(de)深度為一(yi)次(ci)循環(huan)(huan)。電(dian)(dian)池(chi)(chi)循環(huan)(huan)次(ci)數(shu)越(yue)(yue)多，則壽(shou)(shou)命越(yue)(yue)長，電(dian)(dian)動自行(xing)(xing)(xing)車蓄(xu)電(dian)(dian)池(chi)(chi)循環(huan)(huan)壽(shou)(shou)命不少于(yu)(yu)(yu)350次(ci)，低于(yu)(yu)(yu)350次(ci)循環(huan)(huan)為不合格(ge)電(dian)(dian)池(chi)(chi)。就(jiu)現在(zai)市面(mian)上(shang)電(dian)(dian)動自行(xing)(xing)(xing)車而言，一(yi)般情(qing)況下，用于(yu)(yu)(yu)上(shang)、下班或接(jie)送小孩上(shang)學，在(zai)城市范圍內每天(tian)連續行(xing)(xing)(xing)駛1個小時(shi)左右(you)（大(da)約25公(gong)里(li)），一(yi)年(nian)下來相(xiang)當(dang)于(yu)(yu)(yu)電(dian)(dian)池(chi)(chi)循環(huan)(huan)180次(ci)左右(you)，如果是合格(ge)的(de)電(dian)(dian)池(chi)(chi)，可使用近兩年(nian)時(shi)間，此時(shi)電(dian)(dian)池(chi)(chi)容(rong)量還有額(e)定的(de)70％，相(xiang)當(dang)于(yu)(yu)(yu)電(dian)(dian)動車還可連續行(xing)(xing)(xing)駛70分(fen)鐘(zhong)，大(da)約行(xing)(xing)(xing)駛30公(gong)里(li)。
4、電池額定電壓及電池組工作(zuo)電壓
國家標準規定的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)壓值(zhi)為額定電(dian)(dian)(dian)(dian)(dian)壓，用(yong)V伏特表示，鉛酸電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)每(mei)格(ge)電(dian)(dian)(dian)(dian)(dian)壓值(zhi)為2V，市場上的(de)電(dian)(dian)(dian)(dian)(dian)動(dong)車(che)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)每(mei)格(ge)只(zhi)有6V和12V。每(mei)只(zhi)6V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是由3個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)單格(ge)串聯組成，12V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是由6個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)單格(ge)串聯而(er)成。大部(bu)分電(dian)(dian)(dian)(dian)(dian)動(dong)自行(xing)車(che)用(yong)的(de)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)為36V，則由6只(zhi)6V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)或3只(zhi)12V電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)再串聯形(xing)成電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組。
電(dian)(dian)池(chi)(chi)組(zu)工作(zuo)電(dian)(dian)壓，是指蓄電(dian)(dian)池(chi)(chi)組(zu)實(shi)際輸出電(dian)(dian)能時的電(dian)(dian)壓值，36V電(dian)(dian)池(chi)(chi)組(zu)工作(zuo)電(dian)(dian)壓一般在41V到31.5V之(zhi)間，低于31.5V電(dian)(dian)池(chi)(chi)稱為過(guo)放電(dian)(dian)或稱欠壓，容(rong)易損壞電(dian)(dian)池(chi)(chi)組(zu)，影響(xiang)電(dian)(dian)池(chi)(chi)使用壽命。
