電(dian)動自行(xing)車鉛酸(suan)電(dian)池指標有以(yi)下4個方(fang)面：
1、電池額定容量
是按國家標準規定的(de)電池容量。單位用Ah即安(an)時來表示，它(ta)反映了電池存儲電量的(de)大小。數值越大，則存儲的(de)電量就越多(duo)，現在市場上的(de)電動車蓄電池的(de)容量一般都是10Ah，以恒流5A放電120分鐘。
2、電池的實際容量
反映電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)實(shi)際(ji)(ji)存儲(chu)電(dian)(dian)(dian)(dian)(dian)量的(de)大(da)(da)小，單位用Ah安(an)時(shi)表(biao)示。同樣(yang)安(an)時(shi)越(yue)大(da)(da)，則電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容量就越(yue)大(da)(da)，電(dian)(dian)(dian)(dian)(dian)動(dong)車的(de)續行里程(cheng)就越(yue)遠。在(zai)使用過程(cheng)中，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)實(shi)際(ji)(ji)容量會(hui)逐步(bu)衰(shuai)減(jian)。國家標準(zhun)規定新出廠的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)實(shi)際(ji)(ji)容量大(da)(da)于額定容量值(zhi)為合格電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。如現在(zai)市場(chang)上(shang)電(dian)(dian)(dian)(dian)(dian)動(dong)自行車的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，以恒(heng)電(dian)(dian)(dian)(dian)(dian)流5A放(fang)電(dian)(dian)(dian)(dian)(dian)要(yao)超過2小時(shi)（120分鐘(zhong)），大(da)(da)于（2小時(shi)×5A）10Ah。相當(dang)于電(dian)(dian)(dian)(dian)(dian)動(dong)車在(zai)平坦的(de)路上(shang)連續行駛2小時(shi)以上(shang)。
3、放電循環壽命
指的是電池(chi)進行(xing)(xing)充(chong)電、放電直到電池(chi)容(rong)(rong)量減少到額定(ding)容(rong)(rong)量70％時的循(xun)環(huan)次數(shu)，充(chong)足(zu)電后再放電到一定(ding)的深(shen)度為一次循(xun)環(huan)。電池(chi)循(xun)環(huan)次數(shu)越(yue)多，則壽命(ming)越(yue)長，電動(dong)自行(xing)(xing)車(che)蓄電池(chi)循(xun)環(huan)壽命(ming)不(bu)少于(yu)350次，低于(yu)350次循(xun)環(huan)為不(bu)合格電池(chi)。就(jiu)現在市面上(shang)電動(dong)自行(xing)(xing)車(che)而言，一般情況下，用(yong)于(yu)上(shang)、下班或接送小(xiao)(xiao)孩上(shang)學，在城市范(fan)圍內每天連(lian)續(xu)行(xing)(xing)駛(shi)(shi)1個小(xiao)(xiao)時左右（大(da)約25公里(li)），一年下來相當于(yu)電池(chi)循(xun)環(huan)180次左右，如(ru)果(guo)是合格的電池(chi)，可(ke)使用(yong)近兩年時間，此時電池(chi)容(rong)(rong)量還(huan)(huan)有額定(ding)的70％，相當于(yu)電動(dong)車(che)還(huan)(huan)可(ke)連(lian)續(xu)行(xing)(xing)駛(shi)(shi)70分鐘(zhong)，大(da)約行(xing)(xing)駛(shi)(shi)30公里(li)。
4、電池額定(ding)電壓及(ji)電池組工(gong)作電壓
國家標準(zhun)規定(ding)的電池(chi)電壓值為(wei)額定(ding)電壓，用V伏特(te)表(biao)示(shi)，鉛酸電池(chi)每(mei)格電壓值為(wei)2V，市場(chang)上的電動(dong)車蓄(xu)電池(chi)每(mei)格只(zhi)(zhi)有6V和12V。每(mei)只(zhi)(zhi)6V電池(chi)是(shi)由(you)3個(ge)電池(chi)單(dan)格串(chuan)聯組成，12V電池(chi)是(shi)由(you)6個(ge)電池(chi)單(dan)格串(chuan)聯而成。大部分電動(dong)自行車用的蓄(xu)電池(chi)為(wei)36V，則由(you)6只(zhi)(zhi)6V電池(chi)或3只(zhi)(zhi)12V電池(chi)再串(chuan)聯形(xing)成電池(chi)組。
電(dian)(dian)池組(zu)(zu)工(gong)作電(dian)(dian)壓(ya)，是指蓄電(dian)(dian)池組(zu)(zu)實際輸出電(dian)(dian)能時的(de)電(dian)(dian)壓(ya)值，36V電(dian)(dian)池組(zu)(zu)工(gong)作電(dian)(dian)壓(ya)一般在(zai)41V到31.5V之間(jian)，低于31.5V電(dian)(dian)池稱(cheng)為過放電(dian)(dian)或(huo)稱(cheng)欠(qian)壓(ya)，容易(yi)損壞電(dian)(dian)池組(zu)(zu)，影響電(dian)(dian)池使用壽命(ming)。
