鋰電池電動車怎么樣

現在市面上，賣的最多的還是鉛酸電池電動車，但有不(bu)少地區開始引進鋰(li)(li)(li)(li)電(dian)池(chi)(chi)(chi)電(dian)動車了。鋰(li)(li)(li)(li)電(dian)池(chi)(chi)(chi)電(dian)動車顧名思義，簡單(dan)來(lai)說就是(shi)(shi)把(ba)鉛(qian)酸換成了鋰(li)(li)(li)(li)電(dian)池(chi)(chi)(chi)而(er)已。那和鉛(qian)酸電(dian)池(chi)(chi)(chi)相比(bi)，電(dian)動車鋰(li)(li)(li)(li)電(dian)池(chi)(chi)(chi)好(hao)不(bu)好(hao)？它真的(de)有企(qi)業，經銷商說的(de)那么傳神么？如今(jin)國(guo)家大(da)力提倡節能、綠色、環保，一說到電(dian)動車鋰(li)(li)(li)(li)電(dian)池(chi)(chi)(chi)好(hao)不(bu)好(hao)？大(da)家觀(guan)點(dian)都非(fei)常一致，“鋰(li)(li)(li)(li)電(dian)池(chi)(chi)(chi)比(bi)鉛(qian)酸電(dian)池(chi)(chi)(chi)要輕，壽(shou)命也長，但是(shi)(shi)價格非(fei)常貴”，但是(shi)(shi)到底好(hao)在哪時(shi)？大(da)家又顯得都回答不(bu)上話來(lai)。

鋰電池電動車有哪些優缺點

鋰電池電動車優點

1、鋰電池壽命長重量輕體積小

鋰電池電動自行車的(de)動力(li)性能和鉛(qian)酸(suan)電(dian)池（簡易款電(dian)動自(zi)行車）差(cha)不多，充電(dian)6~8小時(shi)，根據電(dian)池容量(liang)不同(tong)可跑30~45公里，重(zhong)量(liang)只(zhi)有鉛(qian)酸(suan)電(dian)池的(de)1／5左(zuo)右，鋰(li)電(dian)池電(dian)動自(zi)行車最(zui)大優(you)點是壽(shou)命長。

聲(sheng)明：說鋰電池(chi)價(jia)格貴的只是(shi)看(kan)到表面(mian)，其(qi)實仔細算算費用(yong)和鉛酸(suan)蓄電池(chi)是(shi)差不多的，目前一般鋰電池(chi)保(bao)2年，鉛酸(suan)蓄電池(chi)保(bao)1年。

2、鋰電池具有免激活特性

在(zai)使用(yong)鋰電(dian)(dian)(dian)池(chi)(chi)中應(ying)注意的是(shi)，電(dian)(dian)(dian)池(chi)(chi)放(fang)置一段時(shi)(shi)間后則(ze)進入休眠狀態，此時(shi)(shi)容(rong)量(liang)低于(yu)(yu)正(zheng)常(chang)值，使用(yong)時(shi)(shi)間亦隨之(zhi)縮短。但(dan)鋰電(dian)(dian)(dian)池(chi)(chi)很容(rong)易激(ji)活(huo)，只(zhi)要(yao)(yao)經過3—5次正(zheng)常(chang)的充放(fang)電(dian)(dian)(dian)循環就(jiu)可(ke)激(ji)活(huo)電(dian)(dian)(dian)池(chi)(chi)，恢(hui)復(fu)正(zheng)常(chang)容(rong)量(liang)。由于(yu)(yu)鋰電(dian)(dian)(dian)池(chi)(chi)本身的特性，決(jue)定了它幾乎沒(mei)有記憶效應(ying) 。因此用(yong)戶新鋰電(dian)(dian)(dian)池(chi)(chi)在(zai)激(ji)活(huo)過程中，是(shi)不需要(yao)(yao)特別的方法(fa)和設備的。

3、無記憶效應

消費(fei)者(zhe)在給鉛酸(suan)蓄電(dian)(dian)池(chi)(chi)，鎳電(dian)(dian)池(chi)(chi)充電(dian)(dian)時，一直都擔心電(dian)(dian)池(chi)(chi)發生記憶效應，等用了鋰電(dian)(dian)池(chi)(chi)，大家(jia)都可以松下(xia)一口氣，鋰電(dian)(dian)池(chi)(chi)不(bu)帶記憶效應。要是還有消費(fei)者(zhe)不(bu)知道如何給鋰電(dian)(dian)池(chi)(chi)充電(dian)(dian)，那不(bu)妨看(kan)看(kan)下(xia)面的內容。

鋰電池電動車的缺點

1、鋰電池電動車價格過高皆因鋰電池

目前鋰電池電動自行車的(de)(de)價(jia)格普遍比鉛(qian)酸電(dian)池電(dian)動(dong)車(che)(che)高出幾百元(yuan)到(dao)一千元(yuan)，因此在市面上很(hen)難得到(dao)消費者顧客的(de)(de)認可。鋰電(dian)池輕巧、環保，廢棄(qi)后(hou)不會產生(sheng)環境污染，一旦應(ying)用技術成熟，市場銷量加大，鋰電(dian)池電(dian)動(dong)自行車(che)(che)的(de)(de)價(jia)格才會有(you)所(suo)降(jiang)下來。

2、鋰電池充電時間過長適得其反

鋰電(dian)(dian)(dian)池(chi)或充(chong)(chong)(chong)電(dian)(dian)(dian)器在(zai)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)滿后都會自動(dong)停(ting)充(chong)(chong)(chong)，并不存在(zai)鎳電(dian)(dian)(dian)充(chong)(chong)(chong)電(dian)(dian)(dian)器所(suo)謂的(de)(de)持續10幾小時(shi)的(de)(de)“涓(juan)流”充(chong)(chong)(chong)電(dian)(dian)(dian)。也就是(shi)說(shuo)，如(ru)果你的(de)(de)鋰電(dian)(dian)(dian)池(chi)在(zai)充(chong)(chong)(chong)滿后，放在(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)器上也是(shi)白充(chong)(chong)(chong)。而我們誰都無法保證電(dian)(dian)(dian)池(chi)的(de)(de)充(chong)(chong)(chong)放電(dian)(dian)(dian)保護(hu)電(dian)(dian)(dian)路的(de)(de)特性(xing)永不變化和質(zhi)量的(de)(de)萬無一失，所(suo)以你的(de)(de)電(dian)(dian)(dian)池(chi)將長期(qi)處在(zai)危險的(de)(de)邊緣徘(pai)徊。這也是(shi)我們反對長充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)另(ling)一個(ge)理(li)由。

此外(wai)在某(mou)些電(dian)(dian)動車上(shang)，充(chong)電(dian)(dian)超過一定的(de)時(shi)間后，如果不(bu)去(qu)取下充(chong)電(dian)(dian)器，這(zhe)時(shi)系統不(bu)僅不(bu)停止充(chong)電(dian)(dian)，還將(jiang)開始放電(dian)(dian)-充(chong)電(dian)(dian)循環(huan)。也許(xu)這(zhe)種做法(fa)的(de)廠(chang)商自有其目的(de)，但(dan)顯然對電(dian)(dian)池(chi)的(de)壽命而言是(shi)不(bu)利的(de)。所以在購買鋰(li)電(dian)(dian)池(chi)電(dian)(dian)動車后，要咨詢(xun)企業(ye)或者(zhe)經銷(xiao)商，做好(hao)鋰(li)電(dian)(dian)池(chi)維護工(gong)作。

3、鋰電池動力性有待提高

鋰電(dian)(dian)(dian)池(chi)比起鉛(qian)酸(suan)蓄電(dian)(dian)(dian)池(chi)在(zai)充放(fang)電(dian)(dian)(dian)方面耐波動(dong)的能力差(cha)得多，對于目前大功率車來說不能有效采用(yong)鋰電(dian)(dian)(dian)的一大癥狀也(ye)就(jiu)在(zai)此，導(dao)致耐用(yong)性下降。

4、鋰離子電池安全性問題突出

鋰電池的(de)(de)(de)(de)安全(quan)性仍有待提高。鋰電(dian)池(chi)起(qi)(qi)火(huo)、燃(ran)燒甚至爆炸的(de)(de)(de)(de)隱(yin)患目(mu)前仍無法完全(quan)消除。車輛發(fa)生碰撞(zhuang)可能導(dao)致(zhi)電(dian)池(chi)正負極(ji)材料沖破隔膜(mo)，剎車時(shi)能量快速回充至電(dian)池(chi)時(shi)瞬(shun)間的(de)(de)(de)(de)超高電(dian)流(liu)等原(yuan)因(yin)都會導(dao)致(zhi)電(dian)池(chi)發(fa)生短路、溫度升高，引(yin)起(qi)(qi)燃(ran)燒甚至爆炸。起(qi)(qi)火(huo)的(de)(de)(de)(de)原(yuan)因(yin)是碰撞(zhuang)、短路導(dao)致(zhi)鋰離(li)子(zi)析出，與空氣接(jie)觸會發(fa)生起(qi)(qi)火(huo)、燃(ran)燒。另(ling)外，鋰離(li)子(zi)電(dian)池(chi)的(de)(de)(de)(de)電(dian)解液是有機電(dian)解液，這些(xie)物(wu)質與空氣接(jie)觸后更容(rong)易(yi)起(qi)(qi)火(huo)燃(ran)燒。
