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(chu)廠到(dao)(dao)使(shi)用(yong)(yong)，一(yi)般要經(jing)過1-2個月(yue)，甚(shen)至更長(chang)的時間，電(dian)池(chi)在(zai)存放(fang)(fang)期間由(you)于電(dian)池(chi)內部的自放(fang)(fang)電(dian)等自發反(fan)應，消(xiao)耗了一(yi)部分電(dian)量，達不(bu)到(dao)(dao)額(e)定容(rong)量值(zhi)，所以(yi)初次使(shi)用(yong)(yong)前，最好進行(xing)補充(chong)充(chong)電(dian)，以(yi)免顧客誤認為是容(rong)量不(bu)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(chong)足電(dian)(dian)存(cun)放，并且應該一(yi)個月內至少充(chong)一(yi)次電(dian)(dian)，防止虧電(dian)(dian)，能有效防止晶技生成(cheng)造成(cheng)不可逆鹽化和晶枝短(duan)路(lu)等。

3、 電池使用充電器進行充(chong)電(dian)前要(yao)不要(yao)先(xian)放完電(dian)？

答：電動車鉛酸蓄電池不同于其它二次電池，它無記憶效應，所以，無論電池處(chu)于何種荷電狀態，都可(ke)直接(jie)進行充(chong)電，無須放電。

4、電池是勤充(chong)電好(hao)還是放完電再充(chong)電好(hao)？

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，充電器存在故障(zhang)率高，可(ke)靠(kao)性(xing)差(cha)(cha)，精度低(di)等缺(que)陷。因此，有時勤充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)反(fan)而影響電(dian)(dian)(dian)(dian)(dian)池的使用壽(shou)命(ming)。將電(dian)(dian)(dian)(dian)(dian)池放(fang)空再充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)次(ci)數雖然減少，但放(fang)電(dian)(dian)(dian)(dian)(dian)時由于單體電(dian)(dian)(dian)(dian)(dian)池之間(jian)總會存在差(cha)(cha)異可(ke)能(neng)(neng)造(zao)成某(mou)些單格過(guo)(guo)放(fang)電(dian)(dian)(dian)(dian)(dian)，過(guo)(guo)放(fang)電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)接受能(neng)(neng)力會大大降(jiang)低(di)，引起充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)不足的故障(zhang)，另外由于放(fang)完電(dian)(dian)(dian)(dian)(dian)再充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器重負荷(he)時間(jian)長，易(yi)損壞(huai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器。因此，綜合(he)上述，我們認為蓄 電(dian)(dian)(dian)(dian)(dian)池放(fang)出電(dian)(dian)(dian)(dian)(dian)量的50-70%時進行一次(ci)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)是較(jiao)合(he)理(li)的，對電(dian)(dian)(dian)(dian)(dian)池的使用有好處(chu)。

5、過充電(dian)和欠充電(dian)有什么害處(chu)？

答：過充電即蓄電池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流大于(yu)(yu)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)可(ke)(ke)接(jie)受電(dian)(dian)(dian)(dian)(dian)(dian)流，多出部分即是(shi)(shi)過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)，過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)主要是(shi)(shi)產(chan)生(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)解水(shui)的副反應，由于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)正極產(chan)生(sheng)(sheng)氧氣轉移到負(fu)極發生(sheng)(sheng)氧復合(he)反應，會發生(sheng)(sheng)熱量(liang)，因(yin)此過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)實際(ji)轉換成熱量(liang)使電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)溫度升高，若(ruo)不(bu)加(jia)以控制，會造成大量(liang)失(shi)水(shui)，嚴(yan)重者(zhe)造成“熱失(shi)控”容(rong)量(liang)劇減，甚至變形(xing)等故障。欠充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)通俗(su)講就是(shi)(shi)未充(chong)(chong)飽電(dian)(dian)(dian)(dian)(dian)(dian)經(jing)常處于(yu)(yu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)不(bu)足的情況下，極極就會逐漸形(xing)成一(yi)種粗大堅硬(ying)的硫酸鉛，它幾乎不(bu)溶(rong)解，即產(chan)生(sheng)(sheng)所謂的“不(bu)可(ke)(ke)逆硫酸鹽化”，使用普通的方法(fa)無法(fa)充(chong)(chong)進電(dian)(dian)(dian)(dian)(dian)(dian)，因(yin)此容(rong)量(liang)會一(yi)次(ci)一(yi)次(ci)地快(kuai)速衰減。

6、過放電對電池(chi)有什么害處？

電(dian)(dian)(dian)池(chi)在放電(dian)(dian)(dian)過程中正極活(huo)性物質(zhi)，負(fu)極活(huo)性物質(zhi)均(jun)逐(zhu)漸轉化成(cheng)電(dian)(dian)(dian)阻(zu)很大(da)PBSO4，并消耗電(dian)(dian)(dian)解(jie)液中的(de)硫(liu)酸(suan)(suan)，內阻(zu)逐(zhu)漸增大(da)，因(yin)此(ci)過放電(dian)(dian)(dian)時，特別是以較大(da)電(dian)(dian)(dian)流過放電(dian)(dian)(dian)會發出大(da)量(liang)熱量(liang)，并且電(dian)(dian)(dian)池(chi)的(de)硫(liu)酸(suan)(suan)量(liang)很少，過放電(dian)(dian)(dian)時硫(liu)酸(suan)(suan)濃(nong)度減得很低，PBSO4溶解(jie)度大(da)幅度增加，因(yin)此(ci)容易(yi)在極板上形成(cheng)一種粗大(da)堅硬(ying)的(de)PBSO4晶體，即“不(bu)可逆(ni)硫(liu)酸(suan)(suan)鹽(yan)化”大(da)大(da)地(di)減弱電(dian)(dian)(dian)池(chi)的(de)充電(dian)(dian)(dian)接受能力，危害特別大(da)。

7、電動車電池使用時需要補液嗎？

答：一般情況下無需補(bu)液(ye)，由于電(dian)(dian)動助力車鉛酸密(mi)(mi)封電(dian)(dian)池屬(shu)一種閥控密(mi)(mi)封電(dian)(dian)池，正常使用過程中發生氧復(fu)合反應(ying)，使其(qi)水(shui)耗量(liang)極(ji)少(shao)，在正常壽命(ming)期間無需補(bu)加(jia)(jia)電(dian)(dian)解液(ye)或(huo)水(shui)。但由于受使用環境條件和充電(dian)(dian)的影(ying)響可能(neng)會有一些電(dian)(dian)池失水(shui)量(liang)較大(da)，甚至(zhi)發生干涸(he)現(xian)象(xiang)，此時應(ying)對其(qi)補(bu)加(jia)(jia)電(dian)(dian)解液(ye)或(huo)純水(shui)，補(bu)加(jia)(jia)電(dian)(dian)解液(ye)密(mi)(mi)度為1.05g/cm 的稀硫酸或(huo)純水(shui)，使失水(shui)較嚴重的電(dian)(dian)池重新(xin)恢復(fu)正常。補(bu)液(ye)后還應(ying)將多余的游離液(ye)抽出。

8、電(dian)動(dong)車(che)電(dian)池(chi)什么情況下(xia)需進(jin)行維護(hu)充(chong)電(dian)，其充(chong)電(dian)參(can)數怎(zen)樣，怎(zen)樣進(jin)行維護(hu)充(chong)電(dian)？

答：電動車電池遇下列情況之一時需要進行維護充電：1、電池容量衰減減速太快；2、出現落后電(dian)(dian)池(chi)(chi)(chi)；3、電(dian)(dian)池(chi)(chi)(chi)失液(ye)后，重新補液(ye)；4、電(dian)(dian)池(chi)(chi)(chi)長時間(jian)放置后；5、電(dian)(dian)池(chi)(chi)(chi)出現嚴重過放電(dian)(dian)后；6、電(dian)(dian)池(chi)(chi)(chi)長時間(jian)處于(yu)低溫環境工作等(deng)；7、充(chong)(chong)電(dian)(dian)參(can)(can)數不合理長期欠充(chong)(chong)電(dian)(dian)；維護充(chong)(chong)電(dian)(dian)的充(chong)(chong)電(dian)(dian)參(can)(can)數怎(zen)樣定；一(yi)(yi)般采用恒壓限流(liu)充(chong)(chong)電(dian)(dian)或(huo)多階段恒流(liu)充(chong)(chong)電(dian)(dian)。充(chong)(chong)電(dian)(dian)前中期與(yu)車配充(chong)(chong)電(dian)(dian)器參(can)(can)數基(ji)本一(yi)(yi)致，只是充(chong)(chong)電(dian)(dian)后期將充(chong)(chong)電(dian)(dian)最高(gao)(gao)電(dian)(dian)壓提高(gao)(gao)到(dao)16V/只或(huo)更高(gao)(gao)。即采用高(gao)(gao)電(dian)(dian)壓過充(chong)(chong)電(dian)(dian)，進行深度充(chong)(chong)電(dian)(dian)修復已落后電(dian)(dian)池(chi)(chi)(chi)。維護充(chong)(chong)電(dian)(dian)也叫均衡充(chong)(chong)電(dian)(dian)。

9、電(dian)池初始容量(liang)大小(xiao)與壽命(ming)有什么關(guan)系？

答：電(dian)(dian)池容量受活性(xing)(xing)物質(zhi)(zhi)和利用率(lv)影響。電(dian)(dian)動(dong)助力車蓄電(dian)(dian)池外(wai)形尺寸一(yi)定，極(ji)板(ban)的(de)質(zhi)(zhi)量已被限制到(dao)一(yi)定的(de)程度，只有提(ti)(ti)(ti)高活性(xing)(xing)物質(zhi)(zhi)的(de)利用率(lv)，才能提(ti)(ti)(ti)高容量。要(yao)提(ti)(ti)(ti)高電(dian)(dian)池容量，必然增(zeng)加(jia)(jia)孔(kong)率(lv)，提(ti)(ti)(ti)高PbO2含量、硫酸比重，但是這(zhe)些措(cuo)施(shi)都會(hui)加(jia)(jia)速(su)正(zheng)極(ji)板(ban)的(de)軟化，造(zao)成電(dian)(dian)池壽命加(jia)(jia)速(su)衰減，充(chong)放電(dian)(dian)過程中活性(xing)(xing)物質(zhi)(zhi)會(hui)產(chan)生膨脹(zhang)、收縮(suo) (特(te)別(bie)是正(zheng)極(ji)板(ban))，放電(dian)(dian)深(shen)度越深(shen)，活性(xing)(xing)物質(zhi)(zhi)膨脹(zhang)收縮(suo)量越大，更(geng)加(jia)(jia)速(su)活性(xing)(xing)物質(zhi)(zhi)軟化。因此，初始容量偏大時直接(jie)影響蓄電(dian)(dian)池充(chong)放電(dian)(dian)次數(shu)。當然要(yao)滿(man)足使用，要(yao)求初始容量不能太小，需要(yao)一(yi)種(zhong)折中的(de)選擇才能滿(man)足需要(yao)，既保(bao)證延(yan)長壽命，又確(que)保(bao)容量滿(man)足使用要(yao)求。

10、電池電壓高容量就大嗎？

答：電(dian)(dian)池(chi)電(dian)(dian)壓(ya)與(yu)(yu)容量是兩個概念，電(dian)(dian)壓(ya)與(yu)(yu)電(dian)(dian)極材(cai)料和電(dian)(dian)解液濃度相關(guan)，電(dian)(dian)池(chi)的容量是活性(xing)物質經電(dian)(dian)化學(xue)反應(ying)(ying)產生(sheng)電(dian)(dian)流而(er)釋放(fang)出(chu)來的，它與(yu)(yu)各(ge)活性(xing)物質的量，反應(ying)(ying)條件及利用率，連接等有關(guan)，因此電(dian)(dian)壓(ya)高(gao)不能(neng)說容量就高(gao)，電(dian)(dian)壓(ya)低也不一定容量就低。

11、溫度對電(dian)池性能(neng)有什(shen)么影(ying)響？

答：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)、放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)化學(xue)反(fan)(fan)應，溫(wen)度(du)(du)(du)越高，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)各活(huo)性(xing)物質的活(huo)度(du)(du)(du)增加，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液(ye)粘度(du)(du)(du)降(jiang)低(di)(di)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻減小，因此電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)化學(xue)反(fan)(fan)應容易進(jin)(jin)行，反(fan)(fan)之則不容易進(jin)(jin)行。放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時溫(wen)度(du)(du)(du)越低(di)(di)，放出(chu)(chu)容量(liang)越低(di)(di)，在特別低(di)(di)的溫(wen)度(du)(du)(du)下，放出(chu)(chu)容量(liang)將(jiang)大幅(fu)度(du)(du)(du)下降(jiang)，溫(wen)度(du)(du)(du)高則相反(fan)(fan)；充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時溫(wen)度(du)(du)(du)越低(di)(di)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)受能(neng)(neng)(neng)力(li)越差(cha)，要(yao)(yao)求充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較高，才(cai)(cai)能(neng)(neng)(neng)充(chong)足電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。反(fan)(fan)之溫(wen)度(du)(du)(du)越高，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)受能(neng)(neng)(neng)力(li)越好，易造成(cheng)過充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，因此要(yao)(yao)求降(jiang)低(di)(di)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，才(cai)(cai)不至(zhi)于造成(cheng)過充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。此溫(wen)度(du)(du)(du)的變化，直(zhi)接(jie)影響(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)能(neng)(neng)(neng)。

12、電(dian)動(dong)車電(dian)池循環次(ci)數是一定的(de)嗎？

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%
循環次(ci)數 350次(ci) 550次(ci) 1000次(ci) 2800次(ci) 7000次(ci)
