電動車逐漸成為廣大市民的主要交通工具，由于大多數市民不懂得電池的充電放電原理，不能按正確的方法充電，致使電池使用一年左右就報廢。那么，電動車充電多長時間好？電動車電池保養你做到了嗎？在這里小編提醒廣大市民除了要選購有質量保證的電動車電池品牌外，我們還應(ying)注意(yi)電(dian)動(dong)車電(dian)池(chi)充電(dian)時間，只有在日常生活中多多注意(yi)和好好保養，電(dian)動(dong)車電(dian)池(chi)才能延長它的使用壽(shou)命。

1.買車或(huo)更換電(dian)池后(hou)，電(dian)池應該有80％左右的電(dian)量，到家就應該充電(dian)，時間是以充電(dian)器變燈后(hou)再(zai)充4小時為(wei)宜。

2.以后每天(tian)（36v騎過(guo)10公(gong)里(li)，48v騎過(guo)15公(gong)里(li)）要堅持充(chong)電(dian)，但是充(chong)電(dian)的時間不(bu)要過(guo)長，以充(chong)電(dian)器變燈后一個小時為宜。充(chong)電(dian)時寧可欠(qian)充(chong)一些，也不(bu)要過(guo)充(chong)，否則電(dian)池會被(bei)充(chong)的因為缺(que)水后，鼓包，腫(zhong)漲。造成對電(dian)池不(bu)可補救的損失。

3.不要讓水(shui)進入電池盒內，以造(zao)成殼(ke)體(ti)內電池聯(lian)電。

4.每個月定期一次完全放(fang)電(dian)(dian)（騎到“欠壓”燈亮起），然后連續(xu)充(chong)電(dian)(dian)12小(xiao)時。

5.有條件的對(dui)整組電池(chi)(chi)里的單(dan)體(ti)(ti)對(dui)調一下，對(dui)過了(le)質保期的電池(chi)(chi)（尤其是到了(le)夏天(tian)），每隔(ge)三，四個月(yue)要對(dui)電池(chi)(chi)每個單(dan)體(ti)(ti)加3-4毫升的去離子(zi)水(shui)（娃哈哈純凈水(shui)也可）。

6.一(yi)旦(dan)發現充電(dian)(dian)器(qi)不轉(zhuan)綠燈或(huo)一(yi)充電(dian)(dian)就轉(zhuan)綠燈，一(yi)定(ding)要(yao)檢查是(shi)不是(shi)充電(dian)(dian)器(qi)有問題(ti)，或(huo)者失水。

7.整組電池的放電口(kou)與充(chong)電口(kou)要隨時保持清潔，防止接觸(chu)點出現銅(tong)銹，造(zao)成(cheng)接觸(chu)不良發生過熱而損壞(huai)。

8.有腳(jiao)踏的(de)盡(jin)量用腳(jiao)起(qi)步，不要負荷太大，加速平(ping)緩(huan)。不要坐上車(che)就(jiu)給電(dian)起(qi)動。

由(you)(you)于放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)越(yue)深越(yue)淺，其循(xun)環次數(shu)將大幅(fu)度增加。因此(ci)，按(an)這一理論，勤(qin)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)對(dui)循(xun)環壽命(ming)是(shi)有益的(de)(de)，但就目前市(shi)場上大量(liang)流(liu)通(tong)使用(yong)(yong)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)來(lai)講，由(you)(you)于受(shou)價格(ge)(ge)因素及技(ji)術(shu)水平等影響，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)存在(zai)故障率高，可靠性差(cha)，精度低(di)等缺(que)陷。因此(ci)，有時勤(qin)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)反而影響電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)使用(yong)(yong)壽命(ming)。將電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)(fang)(fang)空再充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)次數(shu)雖然減少，但放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)時由(you)(you)于單體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)之(zhi)間總會存在(zai)差(cha)異可能造成某(mou)些(xie)單格(ge)(ge)過(guo)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，過(guo)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)接受(shou)能力會大大降低(di)，引起(qi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)不足(zu)的(de)(de)故障，另外由(you)(you)于放(fang)(fang)(fang)完(wan)電(dian)(dian)(dian)(dian)(dian)(dian)再充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)重負荷時間長，易損壞充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。因此(ci)，綜合上述，我們認(ren)為蓄電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)(fang)(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)的(de)(de)50-70%時進行一次充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)較合理的(de)(de)，對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)使用(yong)(yong)有好處(chu)。

過(guo)充(chong)電(dian)(dian)(dian)(dian)即(ji)蓄電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流大于蓄電(dian)(dian)(dian)(dian)池(chi)可接受電(dian)(dian)(dian)(dian)流，多(duo)出部分即(ji)是過(guo)充(chong)電(dian)(dian)(dian)(dian)量，過(guo)充(chong)電(dian)(dian)(dian)(dian)主要是產(chan)(chan)生(sheng)(sheng)電(dian)(dian)(dian)(dian)解(jie)水的副反應，由于電(dian)(dian)(dian)(dian)池(chi)正極產(chan)(chan)生(sheng)(sheng)氧氣轉移到負極發生(sheng)(sheng)氧復合反應，會(hui)發生(sheng)(sheng)熱(re)量，因此過(guo)充(chong)電(dian)(dian)(dian)(dian)量實際轉換成熱(re)量使電(dian)(dian)(dian)(dian)池(chi)溫度升高，若不(bu)(bu)加(jia)以控制，會(hui)造成大量失(shi)(shi)水，嚴重者(zhe)造成“熱(re)失(shi)(shi)控”容量劇減，甚至變形(xing)等(deng)故障。欠充(chong)電(dian)(dian)(dian)(dian)通(tong)(tong)俗講(jiang)就是未充(chong)飽電(dian)(dian)(dian)(dian)經常處(chu)于充(chong)電(dian)(dian)(dian)(dian)不(bu)(bu)足的情(qing)況下，極極就會(hui)逐漸形(xing)成一種粗大堅硬的硫酸鉛，它幾乎不(bu)(bu)溶解(jie)，即(ji)產(chan)(chan)生(sheng)(sheng)所謂的“不(bu)(bu)可逆硫酸鹽(yan)化”，使用普通(tong)(tong)的方法無法充(chong)進(jin)電(dian)(dian)(dian)(dian)，因此容量會(hui)一次一次地快速衰減。

1.首(shou)先是電池(chi)不能(neng)粘水(shui)，如果下雨天(tian)有打濕電池(chi)的情(qing)況，或充電時(shi)(shi)發(fa)生碰(peng)水(shui)，及時(shi)(shi)用干抹(mo)布(bu)搽干；

2.不能(neng)超(chao)載行使(shi)，特別是不能(neng)在上坡段超(chao)載，因為突然加大電流，會對(dui)電池造(zao)成(cheng)傷害；

3.電池充(chong)電時間一定要均勻(yun)，不能(neng)今天(tian)晚上(shang)充(chong)6小(xiao)時，明天(tian)充(chong)8小(xiao)時。一次充(chong)電一定要充(chong)滿，不充(chong)滿使用會降低電池的壽命；

4.使(shi)(shi)用電(dian)(dian)(dian)子修復器進行電(dian)(dian)(dian)動車電(dian)(dian)(dian)池(chi)修復，這樣可(ke)以(yi)有效(xiao)的(de)(de)將(jiang)電(dian)(dian)(dian)池(chi)內部的(de)(de)硫化鉛(qian)晶體有效(xiao)的(de)(de)分解，延長(chang)電(dian)(dian)(dian)池(chi)的(de)(de)使(shi)(shi)用壽命(ming)（使(shi)(shi)用證明(ming)可(ke)有效(xiao)的(de)(de)延長(chang)電(dian)(dian)(dian)池(chi)2年(nian)(nian)左(zuo)右(you)）。對使(shi)(shi)用一年(nian)(nian)左(zuo)右(you)的(de)(de)舊電(dian)(dian)(dian)池(chi)，可(ke)有效(xiao)的(de)(de)恢(hui)復到新電(dian)(dian)(dian)池(chi)狀(zhuang)態的(de)(de)80%左(zuo)右(you)，還(huan)能(neng)在(zai)使(shi)(shi)用一年(nian)(nian)左(zuo)右(you)。

答(da)：需要。因蓄電(dian)(dian)(dian)池在(zai)充電(dian)(dian)(dian)過程中會產生氫(qing)氧氣體(ti)，絕大部分氣體(ti)會在(zai)電(dian)(dian)(dian)池內復合成水，只有小部分氣體(ti)會通過安全閥排(pai)出電(dian)(dian)(dian)池外，長久會導致(zhi)電(dian)(dian)(dian)池失水。所以您的(de)電(dian)(dian)(dian)動車在(zai)使用了8-10個月以后或(huo)充電(dian)(dian)(dian)時電(dian)(dian)(dian)源(yuan)箱發燙時最好到電(dian)(dian)(dian)池經營店(dian)(dian)或(huo)維修店(dian)(dian)進行加液維護。

答：不一定(ding)。當蓄電池老化、容量下降(jiang)時(shi)，續航里(li)程會變(bian)短，但以下不屬于蓄電池的問題時(shi)也會導致續航里(li)程變(bian)短：

1、當電(dian)機效率下降時，所做的無(wu)用功增大，浪費電(dian)量，使續航里(li)程變短；

2、劣質充(chong)電(dian)器每天對蓄電(dian)池(chi)(chi)充(chong)電(dian)時欠充(chong)電(dian)，使蓄電(dian)池(chi)(chi)容量不(bu)足(zu)而(er)造成(cheng)續航里程(cheng)下(xia)降(jiang)；

3、控制器不良使電(dian)動車(che)起動電(dian)流過大時間(jian)過程而(er)浪費(fei)電(dian)量，導致電(dian)動車(che)續航里(li)程變短；

4、劣(lie)質電動車各運動部(bu)位摩擦系數(shu)過大或者機(ji)械(xie)傳動阻力過大，也能造成浪費電量，而導致續(xu)航里程變短。

答：1、避免(mian)在高溫(wen)烈日下暴曬，嚴禁在高溫(wen)環境下充電；

2、避免高溫(wen)下行駛(shi)后立即充電(dian)，防止充電(dian)時間過長（正常8小時左右(you)）；

3、電(dian)池充(chong)電(dian)時電(dian)源箱發燙(tang)或不轉綠(lv)燈，應及(ji)時到(dao)電(dian)池經營店或維修店對電(dian)池或充(chong)電(dian)器進行檢(jian)測(ce)維修.

答：1、冬(dong)季使用電動車您會感到(dao)續(xu)航里程明顯(xian)下降（北方更明顯(xian)），這是正常現(xian)象；

2、因低溫環境下(xia)一則蓄(xu)電(dian)池充電(dian)接(jie)受(shou)能力(li)降低，再(zai)則電(dian)解液粘度增大，電(dian)化學反應(ying)(ying)阻力(li)增加，結果導致蓄(xu)電(dian)池容(rong)量下(xia)降。故(gu)您在(zai)(zai)冬季使(shi)用(yong)時應(ying)(ying)避免(mian)將電(dian)動車放在(zai)(zai)室外過夜(ye)或在(zai)(zai)低溫環境下(xia)充電(dian)。

1、電(dian)源(yuan)箱體過于(yu)密封，電(dian)源(yuan)充電(dian)末期產生氫(qing)氣無法溢出；

2、電(dian)源連接線松動、老化或裸(luo)露(lu)在外(wai)，鑰匙接通(tong)放電(dian)時產生火花或因路(lu)面不平震動使線路(lu)產生火花引(yin)燃氫(qing)氣(qi)；

3、電(dian)源(yuan)箱體上(shang)保險絲座松動，在電(dian)池充放電(dian)過程中發熱或產(chan)生(sheng)(sheng)火(huo)花，引燃氫氣而產(chan)生(sheng)(sheng)氣體膨脹，沖破電(dian)源(yuan)上(shang)蓋；

4、蓄電(dian)池(chi)不(bu)得接近明火或高溫熱源(yuan)，不(bu)得將蓄電(dian)池(chi)拋入火中或浸沒在水中，嚴禁在陽光下直接暴曬或充電(dian)；

5、蓄電池不得放置在密(mi)閉的容器中，應保持通風良好；

6、如發現蓄電池(chi)外殼破(po)裂、滲漏(lou)時(shi)，需(xu)更換蓄電池(chi)；

7、電解液為酸性溶(rong)液，如沾到皮膚、衣物上，須(xu)(xu)立即用(yong)大量清水沖洗，嚴(yan)重(zhong)時須(xu)(xu)送(song)醫院治療；

8、蓄電(dian)池不得短路，不得倒置使用。

1.重新配(pei)組(zu)：整(zheng)(zheng)組(zu)電池(chi)(chi)損(sun)環以后，我們往(wang)往(wang)對電池(chi)(chi)進行充放電檢測，在檢驗中(zhong)往(wang)往(wang)會發現一組(zu)電池(chi)(chi)中(zhong)有(you)50％的電池(chi)(chi)并(bing)沒有(you)損(sun)壞。其原因也就是在串連電池(chi)(chi)組(zu)中(zhong)，個別的電池(chi)(chi)落后形成整(zheng)(zheng)組(zu)電池(chi)(chi)功能下降(jiang)，以至(zhi)于整(zheng)(zheng)組(zu)電瓶功能下降(jiang)。

2.補(bu)(bu)水(shui)：對使用了(le)4個月左右的(de)(de)電(dian)(dian)(dian)池(chi)(chi)進行一次補(bu)(bu)水(shui)，可以延長電(dian)(dian)(dian)池(chi)(chi)的(de)(de)使用壽命(ming)，延長時(shi)間平均達到3個月以上。應該注意(yi)的(de)(de)是，每(mei)次補(bu)(bu)水(shui)以后，電(dian)(dian)(dian)池(chi)(chi)都利用處(chu)于過充電(dian)(dian)(dian)狀態(tai)把電(dian)(dian)(dian)池(chi)(chi)由(you)“準貧(pin)液”轉為“貧(pin)液”狀態(tai)，而這個過充電(dian)(dian)(dian)對提高電(dian)(dian)(dian)池(chi)(chi)容量是有好處(chu)的(de)(de)。

3.消除硫化：采(cai)用電池(chi)修復設備，對電池(chi)進行消除硫化的處理。

4.微粒發(fa)生器： 采取微粒發(fa)生器并聯在電(dian)池上，對(dui)電(dian)池進行修復(fu)(fu)。這(zhe)種方法對(dui)修復(fu)(fu)電(dian)池比較好，但(dan)是(shi)由于修復(fu)(fu)的比較徹底，所(suo)以，如果(guo)沒有(you)過放(fang)電(dian)，對(dui)于連續使(shi)用的電(dian)池來說，往往是(shi)徹底消(xiao)除了電(dian)池硫化的可能性。

5.綜合修復方法：對電(dian)(dian)池(chi)(chi)采用定期(qi)檢驗，及時(shi)除硫和(he)補(bu)水，單只電(dian)(dian)池(chi)(chi)充電(dian)(dian)、重新配組。電(dian)(dian)池(chi)(chi)說明，如(ru)果是(shi)免維護，一般不(bu)需(xu)要(yao)加(jia)(jia)水。如(ru)果需(xu)要(yao)加(jia)(jia)水，先(xian)檢測一下電(dian)(dian)動車電(dian)(dian)池(chi)(chi)自身的電(dian)(dian)解液密度，根據不(bu)同的情況(kuang)選(xuan)擇相(xiang)應濃度或(huo)沒有濃度的水進行(xing)補(bu)充，這樣才能讓電(dian)(dian)池(chi)(chi)容量有所增加(jia)(jia)或(huo)延(yan)長(chang)使(shi)用壽命。

電(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)池(chi)可謂是電(dian)(dian)(dian)動(dong)車(che)的心臟，當然得買好的，這不(bu)僅(jin)電(dian)(dian)(dian)池(chi)的壽命更長，好電(dian)(dian)(dian)池(chi)還能使電(dian)(dian)(dian)動(dong)車(che)“延(yan)年(nian)益壽”呢。至于電(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)池(chi)牌子(zi)的選(xuan)擇，您可以參考(kao)十大(da)(da)品牌網(wang)MAIGOO有提供的電(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)池(chi)十大(da)(da)品牌信息：
