隨著電動汽車的普及和慢慢進入電池老化階段，很多朋友對電動汽車電池的保養知(zhi)識越來(lai)越重視(shi)，都(dou)盡可能的想知(zhi)道要怎么樣做(zuo)才可以最大程度的延長(chang)電池(chi)使(shi)用壽(shou)命，那么電動汽車怎么樣延長(chang)電池(chi)壽(shou)命呢(ni)？

1、起步請輕踩

關于電動汽(qi)車來說，起步假(jia)如猛踩加速(su)，會導致(zhi)電池(chi)大電流(liu)放(fang)電，大電流(liu)放(fang)電容易出現硫(liu)酸(suan)鉛結晶，從而損害電池(chi)極(ji)板的物理性能，影響使(shi)用壽命(ming)。

一(yi)般來說，之(zhi)所(suo)以猛踩加速，就是為了(le)獲(huo)取更激烈的提速效果(guo)，但(dan)(dan)但(dan)(dan)但(dan)(dan)，電動(dong)汽車(che)本(ben)身具備強大的動(dong)力輸出性能(neng)，可以瞬(shun)時爆(bao)發，所(suo)以在起(qi)步的時候(hou)輕踩油門就能(neng)獲(huo)得激烈的提速，并不(bu)要(yao)猛踩。

2、防止暴曬及過冷

電(dian)(dian)動汽車(che)停放(fang)應防止(zhi)過(guo)(guo)度暴曬，溫(wen)度過(guo)(guo)高會使電(dian)(dian)池(chi)內部壓(ya)力(li)新增，導致電(dian)(dian)池(chi)失(shi)水，降低(di)電(dian)(dian)池(chi)活(huo)性(xing)，加(jia)速極板軟化，充電(dian)(dian)時電(dian)(dian)池(chi)外殼(ke)過(guo)(guo)熱、鼓膨甚(shen)至(zhi)嚴重(zhong)變(bian)形。過(guo)(guo)冷的環境自然不必多(duo)說，溫(wen)度低(di)電(dian)(dian)池(chi)活(huo)性(xing)降低(di)，電(dian)(dian)池(chi)低(di)溫(wen)保護(hu)狀態下自動放(fang)電(dian)(dian)，新增電(dian)(dian)池(chi)的負擔，降低(di)續航里程。

那該怎么(me)辦呢?最好的辦法就是停(ting)在室內啦，既可以防止夏季暴曬，冬(dong)季也能保(bao)溫啦。

3、充電時間不是(shi)越長越好(hao)

新能源汽車切忌過度(du)充(chong)(chong)電(dian)(dian)(dian)、過度(du)放電(dian)(dian)(dian)和(he)充(chong)(chong)電(dian)(dian)(dian)不(bu)(bu)足，這(zhe)些都會縮(suo)短電(dian)(dian)(dian)瓶(ping)(ping)壽(shou)命。在(zai)使用(yong)過程中(zhong)，應根據實際車輛情況來決定充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)及頻率，假如電(dian)(dian)(dian)量(liang)表指示燈亮起應盡(jin)快充(chong)(chong)電(dian)(dian)(dian)，并且充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)不(bu)(bu)宜過長，否則會形成過度(du)充(chong)(chong)電(dian)(dian)(dian)，使電(dian)(dian)(dian)瓶(ping)(ping)發(fa)熱。如充(chong)(chong)電(dian)(dian)(dian)過程電(dian)(dian)(dian)瓶(ping)(ping)溫(wen)度(du)超過65℃時(shi)，應當立(li)即停止充(chong)(chong)電(dian)(dian)(dian)，以免(mian)發(fa)生危險。

4、防止頻(pin)繁使用(yong)快充(chong)(chong)方式充(chong)(chong)電

現在的電(dian)(dian)(dian)動汽車，基本上都(dou)具備(bei)快充(chong)和慢充(chong)兩種充(chong)電(dian)(dian)(dian)方式。當(dang)然啦，快充(chong)能夠節省更多的充(chong)電(dian)(dian)(dian)時間，但這關于電(dian)(dian)(dian)池(chi)來(lai)說，卻(que)不(bu)是最好的。

快充(chong)的原理就是將(jiang)直流(liu)電(dian)(dian)(dian)直接儲存到電(dian)(dian)(dian)池內，這樣的充(chong)電(dian)(dian)(dian)方式關于電(dian)(dian)(dian)池的要求會(hui)(hui)(hui)非常高(gao)，直流(liu)電(dian)(dian)(dian)的功率很大，充(chong)電(dian)(dian)(dian)中是讓電(dian)(dian)(dian)子加速(su)從正(zheng)極向負極流(liu)動，所以長時間(jian)或者頻繁(fan)快充(chong)，會(hui)(hui)(hui)導致電(dian)(dian)(dian)池組溫(wen)度升高(gao)，電(dian)(dian)(dian)池衰減會(hui)(hui)(hui)快一些。

慢(man)充(chong)則要通過(guo)車載充(chong)電(dian)(dian)機將(jiang)交(jiao)流電(dian)(dian)轉換成(cheng)直流電(dian)(dian)，再儲存到電(dian)(dian)池(chi)內。因為有車載充(chong)電(dian)(dian)機轉換所以關于(yu)電(dian)(dian)池(chi)的沖擊力相(xiang)對小很多，雖然比較費時間(jian)，但對電(dian)(dian)池(chi)來(lai)說也(ye)相(xiang)對溫(wen)柔啦。

5、適(shi)時對充電設備進行保養

電動汽車充(chong)電器(qi)變形、接(jie)觸不良、接(jie)觸面氧化都會導致充(chong)電插(cha)頭發(fa)熱甚(shen)至短路，損害充(chong)電器(qi)進而損害電池。

6、長時間(jian)停(ting)放車輛也要充(chong)好(hao)電

有的車主認為，假如長時間不(bu)使用車輛(liang)，并不(bu)擔(dan)心新能源汽(qi)車在虧(kui)電(dian)(dian)狀態下停(ting)放(fang)，只(zhi)要在下次(ci)使用前將汽(qi)車充好電(dian)(dian)就(jiu)可以了，這(zhe)樣做其實是不(bu)對(dui)(dui)滴。在虧(kui)電(dian)(dian)狀態下存放(fang)電(dian)(dian)池，很容易(yi)出現(xian)硫酸鹽化，硫酸鉛結晶物附(fu)著在極板，對(dui)(dui)電(dian)(dian)池危害(hai)極大。

7、合適的胎壓有助于(yu)延長電池壽命

合(he)適的(de)胎(tai)壓(ya)(ya)，無論是(shi)(shi)對電(dian)動汽車還是(shi)(shi)燃油汽車都相當重要(yao)，胎(tai)壓(ya)(ya)過高過低(di)都會降(jiang)低(di)輪胎(tai)壽命，并且(qie)對行(xing)車安全也造成了一定的(de)威脅。而關于電(dian)池的(de)損害，胎(tai)壓(ya)(ya)過低(di)，將導致摩(mo)擦系數(shu)增(zeng)大(da)，增(zeng)大(da)耗電(dian)量、減(jian)少續航里程。

8、養成定期檢查(cha)的好習慣

不論是傳動驅動汽車(che)，還是新能源(yuan)汽車(che)，對汽車(che)情況定期(qi)檢查都是必不可少的一(yi)個環節。假(jia)如在(zai)使用(yong)過程(cheng)(cheng)中，新能源(yuan)汽車(che)的續行里程(cheng)(cheng)突然大幅度(du)下降，則(ze)很有可能是電(dian)池(chi)組中最少有一(yi)塊電(dian)池(chi)出現問題，這(zhe)時應立即趕往修理(li)廠及時處理(li)。

9、蓄電(dian)池(chi)閑置存(cun)放(fang)時應保證處于滿電(dian)狀態(tai)

當(dang)電池(chi)(chi)(chi)(chi)在時(shi)候(hou)用沒(mei)有及時(shi)充(chong)電，這個時(shi)候(hou)就處(chu)于(yu)虧(kui)電狀(zhuang)態(tai)，在此狀(zhuang)態(tai)下存放(fang)電池(chi)(chi)(chi)(chi)，很容易(yi)出現硫(liu)(liu)酸鹽化，硫(liu)(liu)酸鉛結晶物附著在極(ji)板上，堵(du)塞(sai)電離子通道，造成充(chong)電不(bu)足，電池(chi)(chi)(chi)(chi)容量(liang)下降(jiang)。電池(chi)(chi)(chi)(chi)損壞的嚴(yan)重程度是和虧(kui)電狀(zhuang)態(tai)閑(xian)置的時(shi)間(jian)成正比的，因此，為(wei)了保持電池(chi)(chi)(chi)(chi)的健康(kang)狀(zhuang)態(tai)，在電池(chi)(chi)(chi)(chi)閑(xian)置存放(fang)是也要保證每(mei)個月充(chong)電一次。
