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(dan)有(you)不(bu)少地區開始引進鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)動(dong)車(che)了。鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)動(dong)車(che)顧(gu)名思義，簡單來說就是把鉛酸(suan)換成了鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)而(er)已(yi)。那和鉛酸(suan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)相比，電(dian)(dian)(dian)(dian)動(dong)車(che)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)好(hao)(hao)不(bu)好(hao)(hao)？它真的有(you)企(qi)業，經銷商說的那么(me)傳神么(me)？如(ru)今國家(jia)大力(li)提倡(chang)節能、綠色、環保，一說到電(dian)(dian)(dian)(dian)動(dong)車(che)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)好(hao)(hao)不(bu)好(hao)(hao)？大家(jia)觀點都(dou)非常一致，“鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)比鉛酸(suan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)要輕，壽命(ming)也長，但(dan)是價(jia)格非常貴”，但(dan)是到底好(hao)(hao)在(zai)哪時？大家(jia)又顯得都(dou)回答不(bu)上話來。

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(he)鉛酸(suan)電(dian)池(chi)（簡易款電(dian)動自行車）差不多，充電(dian)6~8小時，根據電(dian)池(chi)容量不同可(ke)跑30~45公里(li)，重量只有(you)鉛酸(suan)電(dian)池(chi)的(de)1／5左(zuo)右，鋰電(dian)池(chi)電(dian)動自行車最大優點是壽命長。

聲明：說鋰電池(chi)(chi)價(jia)格貴的(de)只是看(kan)到表面，其實仔(zi)細算算費用和鉛酸蓄電池(chi)(chi)是差不多的(de)，目前一般(ban)鋰電池(chi)(chi)保(bao)2年(nian)，鉛酸蓄電池(chi)(chi)保(bao)1年(nian)。

2、鋰電池具有免激活特性

在使用(yong)鋰(li)電池(chi)(chi)(chi)中(zhong)應注意的是(shi)，電池(chi)(chi)(chi)放置一段時(shi)(shi)間后則進入(ru)休眠狀態，此時(shi)(shi)容(rong)量低于正常值，使用(yong)時(shi)(shi)間亦(yi)隨之縮短(duan)。但鋰(li)電池(chi)(chi)(chi)很容(rong)易激活(huo)(huo)，只要經過(guo)3—5次正常的充(chong)放電循環就可激活(huo)(huo)電池(chi)(chi)(chi)，恢(hui)復正常容(rong)量。由于鋰(li)電池(chi)(chi)(chi)本身的特(te)性(xing)，決定(ding)了它(ta)幾乎沒有(you)記憶效應 。因此用(yong)戶新鋰(li)電池(chi)(chi)(chi)在激活(huo)(huo)過(guo)程中(zhong)，是(shi)不需要特(te)別的方法和設備的。

3、無記憶效應

消費者(zhe)在給鉛酸蓄電(dian)(dian)池，鎳電(dian)(dian)池充電(dian)(dian)時(shi)，一直都(dou)擔心電(dian)(dian)池發(fa)生記憶效(xiao)(xiao)應(ying)，等(deng)用了鋰(li)電(dian)(dian)池，大家都(dou)可以松(song)下一口(kou)氣(qi)，鋰(li)電(dian)(dian)池不帶記憶效(xiao)(xiao)應(ying)。要是還(huan)有(you)消費者(zhe)不知(zhi)道如何給鋰(li)電(dian)(dian)池充電(dian)(dian)，那(nei)不妨看看下面(mian)的內(nei)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價(jia)格普遍比鉛酸電(dian)池電(dian)動(dong)(dong)車高出幾百(bai)元到一(yi)千元，因此在市面上很難得(de)到消費者顧客的認可。鋰(li)(li)電(dian)池輕巧、環(huan)保，廢棄后不會(hui)產生環(huan)境(jing)污染，一(yi)旦(dan)應(ying)用(yong)技術成熟，市場銷量加大，鋰(li)(li)電(dian)池電(dian)動(dong)(dong)自行車的價(jia)格才(cai)會(hui)有所(suo)降下來。

2、鋰電池充電時間過長適得其反

鋰電(dian)(dian)(dian)(dian)池或充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器在電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)滿后都會自動停充(chong)(chong)(chong)(chong)，并不存(cun)在鎳電(dian)(dian)(dian)(dian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器所謂的(de)(de)持續(xu)10幾(ji)小時的(de)(de)“涓流”充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。也就(jiu)是說，如(ru)果你的(de)(de)鋰電(dian)(dian)(dian)(dian)池在充(chong)(chong)(chong)(chong)滿后，放(fang)在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器上也是白充(chong)(chong)(chong)(chong)。而我(wo)們(men)誰都無法保證電(dian)(dian)(dian)(dian)池的(de)(de)充(chong)(chong)(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)保護電(dian)(dian)(dian)(dian)路的(de)(de)特(te)性(xing)永(yong)不變化(hua)和質量的(de)(de)萬無一失，所以你的(de)(de)電(dian)(dian)(dian)(dian)池將長期處在危險的(de)(de)邊緣徘徊。這(zhe)也是我(wo)們(men)反對(dui)長充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)另一個理由。

此外在某些電(dian)動(dong)車(che)上，充電(dian)超過一定的(de)時間后，如(ru)果不去取下充電(dian)器，這時系統不僅不停(ting)止充電(dian)，還將開(kai)始放電(dian)-充電(dian)循環。也許這種做(zuo)法的(de)廠商自有其目的(de)，但顯(xian)然對電(dian)池的(de)壽命(ming)而(er)言是不利的(de)。所以在購(gou)買鋰(li)電(dian)池電(dian)動(dong)車(che)后，要咨詢企業或者經銷商，做(zuo)好鋰(li)電(dian)池維護工(gong)作(zuo)。

3、鋰電池動力性有待提高

鋰(li)電(dian)(dian)池(chi)比起鉛酸蓄電(dian)(dian)池(chi)在充(chong)放(fang)電(dian)(dian)方面耐波(bo)動的(de)能力差(cha)得多(duo)，對于目前(qian)大功率車來(lai)說不能有效采(cai)用(yong)鋰(li)電(dian)(dian)的(de)一大癥(zheng)狀也就在此，導致耐用(yong)性下降。

4、鋰離子電池安全性問題突出

鋰電池的安全性(xing)仍(reng)有待提高(gao)(gao)。鋰(li)電(dian)池(chi)(chi)起火、燃(ran)燒甚至(zhi)爆炸(zha)的隱患目前仍(reng)無法完全消除。車(che)輛發生(sheng)碰撞(zhuang)可(ke)能(neng)導(dao)致(zhi)電(dian)池(chi)(chi)正負(fu)極材料沖破(po)隔(ge)膜，剎車(che)時能(neng)量(liang)快速回充至(zhi)電(dian)池(chi)(chi)時瞬間(jian)的超高(gao)(gao)電(dian)流等原(yuan)因(yin)都會導(dao)致(zhi)電(dian)池(chi)(chi)發生(sheng)短路(lu)、溫度升高(gao)(gao)，引起燃(ran)燒甚至(zhi)爆炸(zha)。起火的原(yuan)因(yin)是(shi)碰撞(zhuang)、短路(lu)導(dao)致(zhi)鋰(li)離(li)子析出，與空氣接(jie)觸會發生(sheng)起火、燃(ran)燒。另外，鋰(li)離(li)子電(dian)池(chi)(chi)的電(dian)解液是(shi)有機電(dian)解液，這些物質與空氣接(jie)觸后更容易起火燃(ran)燒。
