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(dao)(dao)使用(yong)，一般要經過1-2個月(yue)，甚至更長的(de)時間，電(dian)池在存放(fang)期間由(you)于電(dian)池內(nei)部(bu)的(de)自放(fang)電(dian)等(deng)自發反應，消耗了一部(bu)分電(dian)量(liang)，達不(bu)到(dao)(dao)額定容量(liang)值，所(suo)以初次使用(yong)前，最好進行補充(chong)充(chong)電(dian)，以免顧客誤認為是(shi)容量(liang)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(zu)電(dian)存放，并(bing)且應(ying)該(gai)一個月內(nei)至少充(chong)一次電(dian)，防止虧電(dian)，能(neng)有(you)效(xiao)防止晶技生成造成不可逆鹽化和晶枝短(duan)路等(deng)。

3、 電池使用充電器進行充電前要不(bu)要先放完電？

答：電動車鉛酸蓄電池不同于其它(ta)(ta)二次電(dian)池(chi)，它(ta)(ta)無記憶效應，所以，無論電(dian)池(chi)處(chu)于何(he)種荷電(dian)狀態，都可直接進行(xing)充電(dian)，無須放電(dian)。

4、電池是(shi)勤充電好還是(shi)放(fang)完電再充電好？

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(cun)在故障(zhang)率(lv)高(gao)，可(ke)靠性(xing)差，精度(du)低(di)等缺陷。因此，有(you)時勤充(chong)電(dian)(dian)反而(er)影(ying)響電(dian)(dian)池(chi)的(de)使用壽(shou)命。將電(dian)(dian)池(chi)放(fang)(fang)空再(zai)(zai)充(chong)電(dian)(dian)，充(chong)電(dian)(dian)次(ci)數雖然(ran)減少，但放(fang)(fang)電(dian)(dian)時由于單(dan)體電(dian)(dian)池(chi)之間(jian)(jian)總會(hui)存(cun)在差異可(ke)能(neng)造成(cheng)某些單(dan)格(ge)過放(fang)(fang)電(dian)(dian)，過放(fang)(fang)電(dian)(dian)池(chi)充(chong)電(dian)(dian)接受能(neng)力(li)會(hui)大大降低(di)，引起充(chong)電(dian)(dian)不足的(de)故障(zhang)，另外由于放(fang)(fang)完電(dian)(dian)再(zai)(zai)充(chong)電(dian)(dian)，充(chong)電(dian)(dian)器(qi)重負荷時間(jian)(jian)長(chang)，易損(sun)壞充(chong)電(dian)(dian)器(qi)。因此，綜合上(shang)述(shu)，我(wo)們(men)認為(wei)蓄(xu) 電(dian)(dian)池(chi)放(fang)(fang)出電(dian)(dian)量的(de)50-70%時進行一次(ci)充(chong)電(dian)(dian)是(shi)較合理的(de)，對(dui)電(dian)(dian)池(chi)的(de)使用有(you)好處。

5、過充電和欠充電有什么(me)害處？

答：過充電即蓄電池充(chong)(chong)(chong)電(dian)電(dian)流大于(yu)蓄電(dian)池(chi)可接受電(dian)流，多出部分即是(shi)過(guo)充(chong)(chong)(chong)電(dian)量，過(guo)充(chong)(chong)(chong)電(dian)主要是(shi)產(chan)生電(dian)解水(shui)的副(fu)反應(ying)(ying)，由(you)于(yu)電(dian)池(chi)正(zheng)極產(chan)生氧氣轉移到負極發生氧復合反應(ying)(ying)，會(hui)(hui)(hui)發生熱(re)量，因此(ci)過(guo)充(chong)(chong)(chong)電(dian)量實際轉換成熱(re)量使電(dian)池(chi)溫度升(sheng)高，若不(bu)加以(yi)控制，會(hui)(hui)(hui)造成大量失水(shui)，嚴重者造成“熱(re)失控”容量劇減，甚至變(bian)形(xing)等故(gu)障。欠充(chong)(chong)(chong)電(dian)通(tong)俗(su)講(jiang)就是(shi)未充(chong)(chong)(chong)飽電(dian)經常(chang)處于(yu)充(chong)(chong)(chong)電(dian)不(bu)足的情況下，極極就會(hui)(hui)(hui)逐漸形(xing)成一種粗大堅(jian)硬的硫酸(suan)鉛，它(ta)幾乎不(bu)溶(rong)解，即產(chan)生所謂的“不(bu)可逆硫酸(suan)鹽(yan)化”，使用普通(tong)的方法(fa)無(wu)法(fa)充(chong)(chong)(chong)進(jin)電(dian)，因此(ci)容量會(hui)(hui)(hui)一次一次地快速衰減。

6、過放電對電池(chi)有什(shen)么害(hai)處？

電(dian)(dian)(dian)(dian)池在(zai)放(fang)電(dian)(dian)(dian)(dian)過(guo)程中正極活性(xing)物(wu)質，負極活性(xing)物(wu)質均逐(zhu)漸(jian)轉化成電(dian)(dian)(dian)(dian)阻(zu)很大PBSO4，并(bing)消耗電(dian)(dian)(dian)(dian)解(jie)液中的硫(liu)酸，內阻(zu)逐(zhu)漸(jian)增(zeng)(zeng)大，因此過(guo)放(fang)電(dian)(dian)(dian)(dian)時，特別是以較(jiao)大電(dian)(dian)(dian)(dian)流過(guo)放(fang)電(dian)(dian)(dian)(dian)會發(fa)出大量(liang)熱(re)量(liang)，并(bing)且電(dian)(dian)(dian)(dian)池的硫(liu)酸量(liang)很少，過(guo)放(fang)電(dian)(dian)(dian)(dian)時硫(liu)酸濃度(du)減得(de)很低(di)，PBSO4溶解(jie)度(du)大幅度(du)增(zeng)(zeng)加，因此容易(yi)在(zai)極板(ban)上形成一種粗大堅硬的PBSO4晶體，即“不可逆硫(liu)酸鹽化”大大地減弱(ruo)電(dian)(dian)(dian)(dian)池的充(chong)電(dian)(dian)(dian)(dian)接受(shou)能(neng)力，危害特別大。

7、電動車電池使用時需要補液嗎？

答：一般情況下無(wu)需補液(ye)，由(you)于電(dian)動助力車鉛酸(suan)密封電(dian)池(chi)屬一種閥控密封電(dian)池(chi)，正常使(shi)(shi)用(yong)過程中發生(sheng)氧復合反應，使(shi)(shi)其水耗量極少，在正常壽命期間無(wu)需補加電(dian)解液(ye)或水。但由(you)于受使(shi)(shi)用(yong)環境條件和充(chong)電(dian)的(de)影響(xiang)可能會(hui)有一些電(dian)池(chi)失水量較大，甚(shen)至(zhi)發生(sheng)干涸現象(xiang)，此時應對其補加電(dian)解液(ye)或純(chun)水，補加電(dian)解液(ye)密度為1.05g/cm 的(de)稀硫(liu)酸(suan)或純(chun)水，使(shi)(shi)失水較嚴重(zhong)的(de)電(dian)池(chi)重(zhong)新恢(hui)復正常。補液(ye)后還應將(jiang)多余的(de)游離液(ye)抽出(chu)。

8、電動車電池(chi)什么情況下需進行維護(hu)充電，其充電參數怎樣，怎樣進行維護(hu)充電？

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(tai)快；2、出現落后(hou)(hou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)；3、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)失液(ye)后(hou)(hou)，重(zhong)新補液(ye)；4、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)長時間(jian)放(fang)置后(hou)(hou)；5、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)出現嚴重(zhong)過放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)(hou)；6、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)長時間(jian)處(chu)于低溫環境工作等；7、充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)參數不合理(li)長期(qi)(qi)欠充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)；維護(hu)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)參數怎(zen)樣定；一般采用恒壓(ya)限(xian)流充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)或(huo)多階(jie)段恒流充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)前中期(qi)(qi)與(yu)車(che)配充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器參數基本(ben)一致(zhi)，只是充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)(hou)期(qi)(qi)將充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)最高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)提高(gao)(gao)到16V/只或(huo)更高(gao)(gao)。即(ji)采用高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，進(jin)行深度(du)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)修復已落后(hou)(hou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。維護(hu)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)也叫均衡充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

9、電池初始容量大(da)小(xiao)與壽命有什么關(guan)系？

答：電(dian)池(chi)容(rong)量(liang)(liang)(liang)受活性(xing)物(wu)質(zhi)和利(li)用(yong)(yong)率(lv)(lv)影響(xiang)。電(dian)動助力車蓄電(dian)池(chi)外形尺(chi)寸一(yi)定，極(ji)板(ban)的(de)(de)質(zhi)量(liang)(liang)(liang)已被限制到一(yi)定的(de)(de)程度，只(zhi)有提(ti)高(gao)(gao)活性(xing)物(wu)質(zhi)的(de)(de)利(li)用(yong)(yong)率(lv)(lv)，才能提(ti)高(gao)(gao)容(rong)量(liang)(liang)(liang)。要(yao)(yao)(yao)提(ti)高(gao)(gao)電(dian)池(chi)容(rong)量(liang)(liang)(liang)，必然增(zeng)加(jia)孔率(lv)(lv)，提(ti)高(gao)(gao)PbO2含量(liang)(liang)(liang)、硫(liu)酸比重，但是這些措施都會(hui)加(jia)速正(zheng)極(ji)板(ban)的(de)(de)軟(ruan)化，造(zao)成(cheng)電(dian)池(chi)壽命(ming)加(jia)速衰(shuai)減，充(chong)放(fang)電(dian)過(guo)程中(zhong)活性(xing)物(wu)質(zhi)會(hui)產生膨脹、收(shou)縮(suo) (特別是正(zheng)極(ji)板(ban))，放(fang)電(dian)深(shen)度越深(shen)，活性(xing)物(wu)質(zhi)膨脹收(shou)縮(suo)量(liang)(liang)(liang)越大，更(geng)加(jia)速活性(xing)物(wu)質(zhi)軟(ruan)化。因此，初始容(rong)量(liang)(liang)(liang)偏大時直(zhi)接影響(xiang)蓄電(dian)池(chi)充(chong)放(fang)電(dian)次(ci)數。當然要(yao)(yao)(yao)滿足使用(yong)(yong)，要(yao)(yao)(yao)求初始容(rong)量(liang)(liang)(liang)不能太小，需(xu)要(yao)(yao)(yao)一(yi)種折中(zhong)的(de)(de)選擇才能滿足需(xu)要(yao)(yao)(yao)，既(ji)保證延(yan)長壽命(ming)，又確保容(rong)量(liang)(liang)(liang)滿足使用(yong)(yong)要(yao)(yao)(yao)求。

10、電(dian)池(chi)電(dian)壓高容量就大嗎？

答：電(dian)(dian)池(chi)電(dian)(dian)壓與容(rong)量(liang)是(shi)兩個概念，電(dian)(dian)壓與電(dian)(dian)極(ji)材料(liao)和電(dian)(dian)解液濃度相關，電(dian)(dian)池(chi)的(de)容(rong)量(liang)是(shi)活性物質(zhi)經電(dian)(dian)化學反(fan)應產生(sheng)電(dian)(dian)流而釋放(fang)出來的(de)，它與各活性物質(zhi)的(de)量(liang)，反(fan)應條(tiao)件及利用率，連接等有關，因此電(dian)(dian)壓高(gao)不能(neng)說(shuo)容(rong)量(liang)就高(gao)，電(dian)(dian)壓低也不一(yi)定容(rong)量(liang)就低。

11、溫(wen)度對(dui)電池(chi)性能有什么(me)影響(xiang)？

答：電(dian)(dian)(dian)(dian)(dian)池的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)、放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，在電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)極上發生(sheng)電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學反(fan)應，溫度(du)(du)越(yue)高，電(dian)(dian)(dian)(dian)(dian)池各(ge)活性(xing)(xing)物質的(de)活度(du)(du)增(zeng)加，電(dian)(dian)(dian)(dian)(dian)解液粘度(du)(du)降低(di)，電(dian)(dian)(dian)(dian)(dian)阻(zu)減小，因此(ci)(ci)電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學反(fan)應容(rong)(rong)易(yi)進行，反(fan)之則(ze)不(bu)容(rong)(rong)易(yi)進行。放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)溫度(du)(du)越(yue)低(di)，放(fang)(fang)出容(rong)(rong)量(liang)(liang)越(yue)低(di)，在特(te)別低(di)的(de)溫度(du)(du)下，放(fang)(fang)出容(rong)(rong)量(liang)(liang)將大幅度(du)(du)下降，溫度(du)(du)高則(ze)相反(fan)；充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)溫度(du)(du)越(yue)低(di)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)接(jie)受能(neng)(neng)力(li)越(yue)差(cha)，要求充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)較高，才(cai)能(neng)(neng)充(chong)(chong)足電(dian)(dian)(dian)(dian)(dian)。反(fan)之溫度(du)(du)越(yue)高，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)接(jie)受能(neng)(neng)力(li)越(yue)好(hao)，易(yi)造成過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，因此(ci)(ci)要求降低(di)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)，才(cai)不(bu)至于造成過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。此(ci)(ci)溫度(du)(du)的(de)變化(hua)(hua)，直接(jie)影(ying)響電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)能(neng)(neng)。

12、電(dian)(dian)動(dong)車(che)電(dian)(dian)池循環次數是(shi)一定的嗎？

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)(ci)數(shu) 350次(ci)(ci) 550次(ci)(ci) 1000次(ci)(ci) 2800次(ci)(ci) 7000次(ci)(ci)
