1、 鉛酸蓄電池為什么在初次使用前要使用電動車充電器進行補充充電？

答：電池從出廠到使(shi)用(yong)，一般(ban)要經過1-2個(ge)月(yue)，甚至更長(chang)的時間(jian)，電(dian)(dian)池在存放(fang)期間(jian)由于(yu)電(dian)(dian)池內部的自放(fang)電(dian)(dian)等自發反應，消耗了一部分電(dian)(dian)量(liang)，達不到額定(ding)容量(liang)值，所以初次使(shi)用(yong)前(qian)，最好進行補充充電(dian)(dian)，以免(mian)顧客誤認為(wei)是容量(liang)不足。

2、 電動車如果要存放較長時間應該怎樣對電動車電池進行處理？

答：首先應將電動車電池充足(zu)電(dian)(dian)存放(fang)，并且應該(gai)一個月內至少(shao)充一次電(dian)(dian)，防止(zhi)(zhi)虧電(dian)(dian)，能有效防止(zhi)(zhi)晶(jing)技生(sheng)成造成不可逆(ni)鹽化和晶(jing)枝短(duan)路等。

3、 電池使用充電器進(jin)行(xing)充(chong)電前要(yao)不要(yao)先放(fang)完(wan)電？

答：電動車鉛酸蓄電池不同于(yu)其它二次電(dian)池，它無記憶效應，所以(yi)，無論電(dian)池處于(yu)何種(zhong)荷電(dian)狀態，都可直接進行充電(dian)，無須放(fang)電(dian)。

4、電池是勤充電(dian)好還是放完電(dian)再充電(dian)好？

答：由于放電越深越淺，其循環次數將大幅度增加。因此，按這一理論，勤充電對循環壽命是有益的，但就目前市場上大量流通使用的充電器來講，由于受價格因素及技術水平等影響，充電器存在故(gu)障率高，可(ke)靠性差(cha)，精(jing)度低(di)等缺陷。因此(ci)，有時勤充(chong)電(dian)(dian)(dian)(dian)(dian)反而影響電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使(shi)用(yong)壽命。將電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)(fang)空再充(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)(dian)次數雖然減少，但放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)時由(you)于單體電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)之間總(zong)會存在差(cha)異可(ke)能(neng)造成某些(xie)單格過放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，過放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)接受能(neng)力會大大降低(di)，引(yin)起充(chong)電(dian)(dian)(dian)(dian)(dian)不足的(de)故(gu)障，另外由(you)于放(fang)(fang)完電(dian)(dian)(dian)(dian)(dian)再充(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)(dian)器重負(fu)荷時間長，易損壞充(chong)電(dian)(dian)(dian)(dian)(dian)器。因此(ci)，綜(zong)合(he)(he)上述，我們認為(wei)蓄 電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)(fang)出電(dian)(dian)(dian)(dian)(dian)量(liang)的(de)50-70%時進(jin)行一次充(chong)電(dian)(dian)(dian)(dian)(dian)是(shi)較(jiao)合(he)(he)理的(de)，對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使(shi)用(yong)有好處。

5、過充電和(he)欠充電有什么(me)害(hai)處？

答：過充電即蓄電池充電(dian)(dian)電(dian)(dian)流(liu)大于蓄電(dian)(dian)池可接受電(dian)(dian)流(liu)，多(duo)出部(bu)分即是過充電(dian)(dian)量(liang)，過充電(dian)(dian)主(zhu)要是產生(sheng)電(dian)(dian)解(jie)水的(de)副反應(ying)，由(you)于電(dian)(dian)池正極(ji)(ji)(ji)產生(sheng)氧氣轉(zhuan)移到負極(ji)(ji)(ji)發(fa)(fa)生(sheng)氧復合反應(ying)，會(hui)(hui)發(fa)(fa)生(sheng)熱量(liang)，因(yin)此過充電(dian)(dian)量(liang)實際轉(zhuan)換成熱量(liang)使(shi)電(dian)(dian)池溫度升高，若(ruo)不(bu)加以控制，會(hui)(hui)造成大量(liang)失水，嚴重者造成“熱失控”容量(liang)劇減，甚至變形等故障。欠充電(dian)(dian)通俗講就是未充飽電(dian)(dian)經(jing)常處于充電(dian)(dian)不(bu)足(zu)的(de)情況下，極(ji)(ji)(ji)極(ji)(ji)(ji)就會(hui)(hui)逐漸形成一(yi)種粗大堅(jian)硬的(de)硫酸鉛，它幾(ji)乎不(bu)溶解(jie)，即產生(sheng)所(suo)謂(wei)的(de)“不(bu)可逆硫酸鹽化”，使(shi)用普通的(de)方法(fa)無法(fa)充進電(dian)(dian)，因(yin)此容量(liang)會(hui)(hui)一(yi)次一(yi)次地快(kuai)速衰(shuai)減。

6、過放(fang)電對電池有什么害(hai)處？

電(dian)(dian)(dian)池在放(fang)(fang)電(dian)(dian)(dian)過(guo)程中正極活(huo)(huo)性物質(zhi)(zhi)，負(fu)極活(huo)(huo)性物質(zhi)(zhi)均逐漸(jian)轉化(hua)成(cheng)電(dian)(dian)(dian)阻(zu)很(hen)大(da)(da)(da)(da)PBSO4，并消耗電(dian)(dian)(dian)解(jie)液中的硫酸(suan)，內阻(zu)逐漸(jian)增(zeng)大(da)(da)(da)(da)，因此過(guo)放(fang)(fang)電(dian)(dian)(dian)時，特別(bie)是以較大(da)(da)(da)(da)電(dian)(dian)(dian)流過(guo)放(fang)(fang)電(dian)(dian)(dian)會(hui)發(fa)出大(da)(da)(da)(da)量熱量，并且電(dian)(dian)(dian)池的硫酸(suan)量很(hen)少，過(guo)放(fang)(fang)電(dian)(dian)(dian)時硫酸(suan)濃度減得很(hen)低，PBSO4溶(rong)解(jie)度大(da)(da)(da)(da)幅度增(zeng)加(jia)，因此容易在極板上形(xing)成(cheng)一種(zhong)粗大(da)(da)(da)(da)堅硬的PBSO4晶體，即“不(bu)可逆硫酸(suan)鹽化(hua)”大(da)(da)(da)(da)大(da)(da)(da)(da)地減弱電(dian)(dian)(dian)池的充電(dian)(dian)(dian)接受(shou)能力，危害特別(bie)大(da)(da)(da)(da)。

7、電動車電池使用時需要補液嗎？

答(da)：一(yi)般情(qing)況下無需補液，由于(yu)(yu)電(dian)動助力車鉛酸(suan)密封電(dian)池(chi)屬一(yi)種閥控密封電(dian)池(chi)，正常(chang)(chang)使(shi)用過程(cheng)中發(fa)生氧復合反應(ying)(ying)，使(shi)其水(shui)(shui)耗量極少，在正常(chang)(chang)壽命期間無需補加電(dian)解(jie)液或水(shui)(shui)。但(dan)由于(yu)(yu)受使(shi)用環(huan)境條(tiao)件(jian)和充電(dian)的影響可(ke)能會有一(yi)些(xie)電(dian)池(chi)失(shi)(shi)水(shui)(shui)量較(jiao)大，甚至(zhi)發(fa)生干(gan)涸現象，此時應(ying)(ying)對其補加電(dian)解(jie)液或純水(shui)(shui)，補加電(dian)解(jie)液密度為1.05g/cm 的稀硫酸(suan)或純水(shui)(shui)，使(shi)失(shi)(shi)水(shui)(shui)較(jiao)嚴重(zhong)(zhong)的電(dian)池(chi)重(zhong)(zhong)新恢復正常(chang)(chang)。補液后還應(ying)(ying)將多余的游(you)離液抽(chou)出。

8、電(dian)(dian)(dian)動車電(dian)(dian)(dian)池(chi)什(shen)么情況下需(xu)進行維護充(chong)電(dian)(dian)(dian)，其(qi)充(chong)電(dian)(dian)(dian)參數(shu)怎(zen)(zen)樣，怎(zen)(zen)樣進行維護充(chong)電(dian)(dian)(dian)？

答：電動車電池遇下列情況之一時需要進行維護充電：1、電池容量衰(shuai)減減速太快；2、出現(xian)落(luo)后電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)；3、電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)失液(ye)后，重新補液(ye)；4、電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)長時間(jian)(jian)放置后；5、電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)出現(xian)嚴(yan)重過放電(dian)(dian)(dian)(dian)(dian)(dian)后；6、電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)長時間(jian)(jian)處于(yu)低溫環境工作等；7、充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)參(can)數不合理長期欠充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)；維護(hu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)參(can)數怎樣定；一(yi)(yi)般采用恒壓限流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)或多(duo)階段恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)前中期與車(che)配充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)參(can)數基本(ben)一(yi)(yi)致，只是充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)后期將充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)最高電(dian)(dian)(dian)(dian)(dian)(dian)壓提高到(dao)16V/只或更高。即采用高電(dian)(dian)(dian)(dian)(dian)(dian)壓過充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，進行深(shen)度充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)修復已落(luo)后電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。維護(hu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)也叫均衡充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。

9、電池初(chu)始容量大小與壽命有什(shen)么關系？

答：電(dian)池容(rong)量(liang)受活(huo)性(xing)物(wu)質(zhi)(zhi)和利用率影響。電(dian)動助力車(che)蓄電(dian)池外形(xing)尺寸一定(ding)(ding)，極(ji)板(ban)的質(zhi)(zhi)量(liang)已被限(xian)制到一定(ding)(ding)的程(cheng)度(du)(du)，只有提(ti)高活(huo)性(xing)物(wu)質(zhi)(zhi)的利用率，才能提(ti)高容(rong)量(liang)。要(yao)提(ti)高電(dian)池容(rong)量(liang)，必然增加孔率，提(ti)高PbO2含量(liang)、硫酸比重(zhong)，但(dan)是(shi)(shi)這些措施(shi)都(dou)會加速(su)正極(ji)板(ban)的軟(ruan)化，造成電(dian)池壽命加速(su)衰(shuai)減，充(chong)放(fang)電(dian)過程(cheng)中活(huo)性(xing)物(wu)質(zhi)(zhi)會產生膨(peng)脹、收(shou)縮 (特別是(shi)(shi)正極(ji)板(ban))，放(fang)電(dian)深度(du)(du)越(yue)深，活(huo)性(xing)物(wu)質(zhi)(zhi)膨(peng)脹收(shou)縮量(liang)越(yue)大，更加速(su)活(huo)性(xing)物(wu)質(zhi)(zhi)軟(ruan)化。因此(ci)，初始容(rong)量(liang)偏大時直接影響蓄電(dian)池充(chong)放(fang)電(dian)次數。當然要(yao)滿(man)足(zu)(zu)使用，要(yao)求(qiu)初始容(rong)量(liang)不能太小，需(xu)要(yao)一種折中的選擇才能滿(man)足(zu)(zu)需(xu)要(yao)，既保證延長壽命，又確保容(rong)量(liang)滿(man)足(zu)(zu)使用要(yao)求(qiu)。

10、電池電壓高(gao)容量(liang)就大嗎？

答：電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)與(yu)容(rong)量(liang)是兩(liang)個(ge)概念，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)極材料和電(dian)(dian)(dian)(dian)(dian)(dian)解液濃度相關(guan)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的容(rong)量(liang)是活(huo)性物質(zhi)經電(dian)(dian)(dian)(dian)(dian)(dian)化學反應產生電(dian)(dian)(dian)(dian)(dian)(dian)流而釋(shi)放出來的，它與(yu)各(ge)活(huo)性物質(zhi)的量(liang)，反應條(tiao)件及(ji)利(li)用率，連(lian)接等(deng)有(you)關(guan)，因此電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)高不能說容(rong)量(liang)就高，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)低(di)也不一定(ding)容(rong)量(liang)就低(di)。

11、溫度對電(dian)池性能有什么(me)影響？

答(da)：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)、放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)化學(xue)反(fan)應(ying)，溫度(du)(du)越高，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池各活性(xing)物質的(de)活度(du)(du)增加(jia)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液粘度(du)(du)降低(di)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻減小，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)化學(xue)反(fan)應(ying)容(rong)易進(jin)行(xing)，反(fan)之則(ze)不(bu)(bu)容(rong)易進(jin)行(xing)。放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)溫度(du)(du)越低(di)，放出容(rong)量越低(di)，在特(te)別低(di)的(de)溫度(du)(du)下(xia)，放出容(rong)量將大幅度(du)(du)下(xia)降，溫度(du)(du)高則(ze)相反(fan)；充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)溫度(du)(du)越低(di)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)接受能(neng)力越差(cha)，要(yao)求充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較(jiao)高，才(cai)能(neng)充(chong)足電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。反(fan)之溫度(du)(du)越高，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)接受能(neng)力越好，易造(zao)成(cheng)過充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因此要(yao)求降低(di)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，才(cai)不(bu)(bu)至(zhi)于造(zao)成(cheng)過充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。此溫度(du)(du)的(de)變化，直接影響電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)能(neng)。

12、電動(dong)車電池循環次數是(shi)一定(ding)的嗎(ma)？

答：循環次數，根據放電深度不同而差別很大，放電深度越深，循環次數越小，放電深度越淺，循環次數越多，有時是呈指數變化，根據試驗結果放電深渡與循環次數聯系如下表：
放電深度 100% 70% 50% 20% 10%
循環(huan)次數 350次 550次 1000次 2800次 7000次
