電(dian)(dian)池(chi)(chi)是鋰電(dian)(dian)動(dong)(dong)車(che)的心臟(zang)，對電(dian)(dian)池(chi)(chi)保養得好壞直接影響到電(dian)(dian)動(dong)(dong)車(che)的騎行，如何保養電(dian)(dian)動(dong)(dong)車(che)電(dian)(dian)池(chi)(chi)才能使(shi)電(dian)(dian)動(dong)(dong)車(che)更好的騎行呢。

1、 電池為什么在初次使用前要進行補充充電？
答：電池從出廠到使用，一般要經過1-2個月，甚至更長的時間，電池在存放期間由于電池內部的自放電等自發反應，消耗一部分電量，達不到額定容量值，所以初次使用前，最好進行補充充電，以免顧客誤認為是容量不足。
2、 電動車如果存放較長時間怎樣對電池進行處理？
答：首先應將電池充足電存放，并且應該一個月內至少充一次電，防止虧電，能有效防止晶技生成造成不可逆鹽化和晶枝短路等。
3、 電(dian)池充電(dian)前要不要先放完(wan)電(dian)？

答：鉛酸蓄電池不同于其它二次電池，它無記憶效應，所以，無論電池處于何種荷電狀態，都可直接進行充電，無須放電。
4、電池是勤充電好還是放完電再充電好？
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的充電器，由于受價格因素技術水平等影響，存在故障率高，可靠性差，精度低等缺陷。因此，有時勤充電會影響電池的壽命。將電池放空再充電，充電次數雖然減少，但放電時由于單體電池之間總會存在差異可能造成某些單格過放電，充電接受能力會大大降低，引起充電不足，另外由于放完電再充電，充電器重負荷時間長，易損壞充電器。綜合上述，我們在電池放出電量50-70%時進行充電最合理。
5、過充電和欠充電有什么害處？
答(da)：過充(chong)電(dian)(dian)(dian)(dian)即(ji)蓄電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)大(da)于(yu)蓄電(dian)(dian)(dian)(dian)池可接受電(dian)(dian)(dian)(dian)流(liu)，過充(chong)電(dian)(dian)(dian)(dian)主要是(shi)產生(sheng)(sheng)(sheng)電(dian)(dian)(dian)(dian)解(jie)水(shui)的副反應，由于(yu)電(dian)(dian)(dian)(dian)池正極產生(sheng)(sheng)(sheng)氧氣轉(zhuan)移到負(fu)極發生(sheng)(sheng)(sheng)氧復(fu)合反應，發生(sheng)(sheng)(sheng)熱量(liang)(liang)，因此過充(chong)電(dian)(dian)(dian)(dian)量(liang)(liang)實際(ji)轉(zhuan)換成(cheng)熱量(liang)(liang)使電(dian)(dian)(dian)(dian)池溫度(du)升高，不加控制，會(hui)造(zao)成(cheng)大(da)量(liang)(liang)失水(shui)，嚴重者出(chu)現變形(xing)等(deng)故障。欠充(chong)電(dian)(dian)(dian)(dian)通(tong)俗講就(jiu)是(shi)未充(chong)飽(bao)電(dian)(dian)(dian)(dian)經(jing)常(chang)處于(yu)充(chong)電(dian)(dian)(dian)(dian)不足，極極就(jiu)會(hui)逐漸形(xing)成(cheng)一種(zhong)粗大(da)堅(jian)硬的硫酸鉛，它幾乎(hu)不溶解(jie)，即(ji)產生(sheng)(sheng)(sheng) “不可逆(ni)硫酸鹽化”，使用普通(tong)的方法無法充(chong)進電(dian)(dian)(dian)(dian)，因此容量(liang)(liang)會(hui)一次一次地快速衰減。

6、電動助力車電池使用時需要補液嗎？
答：一般情(qing)況下無需補液(ye)(ye)，由于電(dian)動(dong)助力(li)車鉛酸(suan)(suan)密封(feng)電(dian)池(chi)屬一種閥(fa)控密封(feng)電(dian)池(chi)，正(zheng)常使(shi)用(yong)過程中發(fa)生(sheng)氧(yang)復合(he)反應，使(shi)其水(shui)耗量(liang)極少，在正(zheng)常壽(shou)命期間(jian)無需補加電(dian)解(jie)液(ye)(ye)或水(shui)。但由于受使(shi)用(yong)環境條件和充(chong)電(dian)的影響可能(neng)會有(you)一些電(dian)池(chi)失(shi)水(shui)量(liang)較大，甚至(zhi)發(fa)生(sheng)干(gan)涸現象，此時應對其補加電(dian)解(jie)液(ye)(ye)或純水(shui)，補加電(dian)解(jie)液(ye)(ye)密度為1.05g/cm 的稀硫酸(suan)(suan)或純水(shui)，使(shi)失(shi)水(shui)較嚴重(zhong)的電(dian)池(chi)重(zhong)新(xin)恢復正(zheng)常。補液(ye)(ye)后還應將多余的游離液(ye)(ye)抽(chou)出。

7、電動車電池什么情況下需進行維護充電？
答： 1、電(dian)池(chi)容(rong)量(liang)衰減(jian)減(jian)速太快；2、出(chu)現落(luo)后(hou)電(dian)池(chi)；3、電(dian)池(chi)失液(ye)后(hou)，重新(xin)補液(ye)；4、電(dian)池(chi)長時(shi)(shi)間放(fang)置后(hou)；5、電(dian)池(chi)出(chu)現嚴(yan)重過放(fang)電(dian)后(hou)；6、電(dian)池(chi)長時(shi)(shi)間處(chu)于低(di)溫環境(jing)工(gong)作(zuo)等(deng)；

8、電池初始容量大小與壽命有什么關系？
答(da)：電(dian)(dian)池(chi)容(rong)量(liang)(liang)受活(huo)(huo)性物(wu)質(zhi)(zhi)(zhi)和利用(yong)率影響(xiang)。電(dian)(dian)動助力車(che)蓄(xu)電(dian)(dian)池(chi)外形尺寸(cun)一定(ding)，極(ji)板(ban)的(de)(de)質(zhi)(zhi)(zhi)量(liang)(liang)已被限制到一定(ding)的(de)(de)程(cheng)度，只有(you)提(ti)(ti)高活(huo)(huo)性物(wu)質(zhi)(zhi)(zhi)的(de)(de)利用(yong)率，才能提(ti)(ti)高容(rong)量(liang)(liang)。要提(ti)(ti)高電(dian)(dian)池(chi)容(rong)量(liang)(liang)，必然增加(jia)(jia)孔率，提(ti)(ti)高PbO2含(han)量(liang)(liang)、硫酸比重，但(dan)是這些措施都會加(jia)(jia)速正(zheng)極(ji)板(ban)的(de)(de)軟化，造成電(dian)(dian)池(chi)壽命加(jia)(jia)速衰減，充(chong)放電(dian)(dian)過程(cheng)中活(huo)(huo)性物(wu)質(zhi)(zhi)(zhi)會產生膨(peng)脹(zhang)、收縮(suo) (特別(bie)是正(zheng)極(ji)板(ban))，放電(dian)(dian)深(shen)度越深(shen)，活(huo)(huo)性物(wu)質(zhi)(zhi)(zhi)膨(peng)脹(zhang)收縮(suo)量(liang)(liang)越大(da)，更加(jia)(jia)速活(huo)(huo)性物(wu)質(zhi)(zhi)(zhi)軟化。因此，初始容(rong)量(liang)(liang)偏(pian)大(da)時直接(jie)影響(xiang)蓄(xu)電(dian)(dian)池(chi)充(chong)放電(dian)(dian)次(ci)數(shu)。

9、電池電壓高容量就大嗎？
答(da)：電(dian)(dian)池電(dian)(dian)壓與容(rong)量(liang)是(shi)兩個概念，電(dian)(dian)壓與電(dian)(dian)極材料和電(dian)(dian)解液濃度(du)相關(guan)，電(dian)(dian)池的容(rong)量(liang)是(shi)活(huo)性(xing)物質(zhi)經電(dian)(dian)化(hua)學反(fan)應產生(sheng)電(dian)(dian)流(liu)而(er)釋放出來的，它與各(ge)活(huo)性(xing)物質(zhi)的量(liang)，反(fan)應條件及(ji)利(li)用率，連接等(deng)有(you)關(guan)，因此電(dian)(dian)壓高(gao)不(bu)能說容(rong)量(liang)就高(gao)，電(dian)(dian)壓低(di)也(ye)不(bu)一定容(rong)量(liang)就低(di)。

10、溫度對電池性能有什么影響？
答：電(dian)(dian)(dian)(dian)池(chi)(chi)的充(chong)電(dian)(dian)(dian)(dian)、放電(dian)(dian)(dian)(dian)時(shi)(shi)，在(zai)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)極上發生電(dian)(dian)(dian)(dian)化學(xue)反應(ying)(ying)，溫度(du)(du)越(yue)(yue)高(gao)(gao)，電(dian)(dian)(dian)(dian)池(chi)(chi)各活(huo)性(xing)物質(zhi)的活(huo)度(du)(du)增(zeng)加(jia)，電(dian)(dian)(dian)(dian)解液粘度(du)(du)降(jiang)低(di)(di)，電(dian)(dian)(dian)(dian)阻減小，因(yin)此電(dian)(dian)(dian)(dian)化學(xue)反應(ying)(ying)容易進行。放電(dian)(dian)(dian)(dian)時(shi)(shi)溫度(du)(du)越(yue)(yue)低(di)(di)，放出容量越(yue)(yue)低(di)(di)，在(zai)特別低(di)(di)的溫度(du)(du)下，放出容量將大幅度(du)(du)下降(jiang)，溫度(du)(du)高(gao)(gao)則(ze)相(xiang)反；充(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)溫度(du)(du)越(yue)(yue)低(di)(di)，充(chong)電(dian)(dian)(dian)(dian)接(jie)受(shou)能力(li)越(yue)(yue)差，要求充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓較高(gao)(gao)，才能充(chong)足電(dian)(dian)(dian)(dian)。反之溫度(du)(du)越(yue)(yue)高(gao)(gao)，充(chong)電(dian)(dian)(dian)(dian)接(jie)受(shou)能力(li)越(yue)(yue)好，易造(zao)成過(guo)充(chong)電(dian)(dian)(dian)(dian)，因(yin)此要求降(jiang)低(di)(di)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓，才不至(zhi)于造(zao)成過(guo)充(chong)電(dian)(dian)(dian)(dian)。

11、電動車電池循環次數是一定的嗎？
答：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，根據試驗放電深度與循環次數聯系如下表：
放電深度 100% 70% 50% 20% 10%
循(xun)環次(ci)(ci)數 350次(ci)(ci) 550次(ci)(ci) 1000次(ci)(ci) 2800次(ci)(ci) 7000次(ci)(ci)
