電動車電池保養方法

1、使用中對電動車電池保養

（1）在(zai)起步、上(shang)橋、爬坡(po)，或頂風行駛時(shi)，應該輔以人力，盡量避免瞬間大電(dian)流放電(dian)。

（2）需加(jia)速時，應緩慢旋轉(zhuan)調速把(ba)，避(bi)免(mian)直接加(jia)快至最快檔。

（3）在路況(kuang)允許的情(qing)況(kuang)下，盡可使電(dian)動車以最高速度行駛。

（4）盡量避免(mian)頻繁剎車、啟動(dong)(dong)，在道路擁擠時(shi)多用(yong)腳蹬驅動(dong)(dong)。

（5）電量顯(xian)示電池(chi)已沒電了，一段時間后，您(nin)會(hui)發現電池(chi)又有(you)小量

電壓，稱為回升電壓，用戶應避(bi)免使用這回升電壓來騎行。

2、充電方面對電動車電池保養

（1）夜間充電，平均時(shi)間在8小(xiao)時(shi)左右，避免(mian)過充(chong)和(he)欠充(chong)。

（2）充(chong)電(dian)時，指示燈顯示滿電(dian)時不要立即(ji)拔下(xia)來，再(zai)浮充(chong)2-3小時。

（3）盡量一(yi)次將電(dian)充(chong)(chong)滿。如確實需要在充(chong)(chong)電(dian)過程(cheng)中騎行，應在騎行完后立即充(chong)(chong)滿。

（4）勤充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)對循環壽命是有益的(de)(de)，但目前市場上(shang)大量流通使用的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)存在故障率高(gao)，可靠性差，精度低(di)等缺陷。因此(ci)，有時勤充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)反而影響(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)使用壽命。而將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)空(kong)再(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，可能造(zao)成(cheng)某些單(dan)格過放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，過放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)受(shou)能力會(hui)大大降低(di)，引起充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)不足的(de)(de)故障，另(ling)外由于(yu)放(fang)完電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)再(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)重負荷時間長，易損壞充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。因此(ci)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量的(de)(de)50-70%時進行(xing)一次充電是較合理(li)的，對電池的壽命有(you)好處。

3、電動車電池保養要注意避免虧電存放

虧電(dian)(dian)狀態是指電(dian)(dian)池使用(yong)后沒有(you)及時充(chong)電(dian)(dian)。在虧電(dian)(dian)狀態下出現硫(liu)酸鹽(yan)化，硫(liu)酸鉛結晶物附在極板(ban)上，堵塞電(dian)(dian)離子通道，造(zao)成電(dian)(dian)池容量下降(jiang)。虧電(dian)(dian)狀態閑置時間越長，電(dian)(dian)池損壞越嚴重。特別是夏天，務必(bi)及時充(chong)電(dian)(dian)。存放(fang)時間每超過一個月就要補充(chong)一次電(dian)(dian)。

4、對電動車電池保養還應及時維護

當電池出現以下情(qing)況須要維護：

（1）長時(shi)間充電不變(bian)綠燈(deng)

（2）電池在充電時發燙

（3）電池容量下降太快

5、電動車電池保養要定期檢驗

在(zai)使用過程中，如果電(dian)動車的續行里(li)程在(zai)短(duan)(duan)時(shi)間內突(tu)然下降十(shi)幾公里(li)，則很(hen)有(you)可能(neng)是電(dian)池(chi)組(zu)中最少(shao)有(you)一塊電(dian)池(chi)出現(xian)斷(duan)格、極板軟化、極板活性物質脫落等短(duan)(duan)路現(xian)象。此時(shi)，應及(ji)時(shi)進行檢查、再生及(ji)配組(zu)。這樣能(neng)相對延(yan)長電(dian)池(chi)組(zu)壽命(ming)，最大程度(du)地節省(sheng)開支。

6、對電動車電池保養還要注意：

電(dian)瓶(ping)在電(dian)動(dong)自(zi)行(xing)(xing)車(che)上安(an)裝要牢固，以防騎行(xing)(xing)時(shi)電(dian)瓶(ping)受振動(dong)損害；經(jing)常清除電(dian)瓶(ping)蓋上的灰塵、污物，注(zhu)意保持電(dian)瓶(ping)干燥、清潔，以防電(dian)瓶(ping)自(zi)行(xing)(xing)放電(dian)。

電動車電池修復方法

萬能表（測電壓用），比重為1.3的稀硫酸電(dian)解液， 針(zhen)筒，功率(lv)50W的12V燈泡（汽車用），或2000W的電爐(lu)絲一小節，恒流充電機（如沒(mei)有的可用(yong)充電器(qi)代用(yong)）

步驟/方法(fa)

1、把電池用燈泡或電爐絲放電到0V，即清零，一點電(dian)都沒有，放(fang)電(dian)時最好是一個(ge)個(ge)來放(fang)或并聯放(fang)電(dian)，這個(ge)工作要一定的時間，之前也可(ke)以(yi)把車(che)騎到(dao)都不能騎再(zai)放(fang)電(dian)，這樣會更快；

2、打開電池上(shang)蓋片，用針筒往電池排氣孔里加比重為1.3的稀硫酸(suan)電(dian)解液加(jia)到富液（加(jia)滿也可），停(ting)20分鐘(zhong)；

3、給加滿電解液的電池充電！如(ru)果(guo)是20AH的電池，用(yong)的是量(liang)程(cheng)為70V的恒流充(chong)電機(ji)，可把4個電(dian)池串聯來同時(shi)充(chong)電(dian)，用(yong)1.5A的電流恒流充(chong)24小(xiao)時，不要限壓(ya)，一般電池就可修復到8-9成新性(xing)能(neng)；如果沒有(you)充(chong)電機(ji)，也(ye)有(you)辦法，就是用我(wo)們平(ping)常充(chong)電動車用的充(chong)電器來充(chong)電，但充(chong)20AH的電池要用充10AH的(de)充電(dian)器（電(dian)流一般是(shi)1.5A-1.8A）來(lai)充(chong)，一個只能充(chong)2-3只(zhi)，時間可充20-24小時.一(yi)般也可把電池恢復。

4、如要修復10AH電池(chi)，則(ze)用以上方(fang)法用1A電(dian)流連續充20-24小時也就可以修復了！但10AH充電器的電流約1.5-1.8A，太大(da)了，可串(chuan)聯一個電阻來減小電流到1A.

5、把(ba)電池里(li)都出來的電解液用(yong)針(zhen)筒抽到貧液就(jiu)可以(yi)了(le)，修復完成(cheng)。
