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(shi)引進(jin)鋰(li)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)動(dong)車(che)了。鋰(li)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)動(dong)車(che)顧名思義，簡單(dan)來說(shuo)就是(shi)把鉛(qian)(qian)酸(suan)換成了鋰(li)電(dian)(dian)(dian)池(chi)而已。那(nei)和鉛(qian)(qian)酸(suan)電(dian)(dian)(dian)池(chi)相比，電(dian)(dian)(dian)動(dong)車(che)鋰(li)電(dian)(dian)(dian)池(chi)好(hao)不(bu)好(hao)？它真(zhen)的(de)有企業(ye)，經銷商(shang)說(shuo)的(de)那(nei)么傳神(shen)么？如(ru)今國家大(da)力(li)提倡節能、綠色、環(huan)保，一(yi)說(shuo)到電(dian)(dian)(dian)動(dong)車(che)鋰(li)電(dian)(dian)(dian)池(chi)好(hao)不(bu)好(hao)？大(da)家觀點都非常一(yi)致(zhi)，“鋰(li)電(dian)(dian)(dian)池(chi)比鉛(qian)(qian)酸(suan)電(dian)(dian)(dian)池(chi)要輕，壽(shou)命也長，但是(shi)價格(ge)非常貴”，但是(shi)到底好(hao)在哪時？大(da)家又顯得都回答不(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)動力性能(neng)和鉛酸電(dian)(dian)池（簡易款(kuan)電(dian)(dian)動自(zi)行車(che)）差不多，充(chong)電(dian)(dian)6~8小時，根據電(dian)(dian)池容量不同可跑30~45公里，重量只(zhi)有鉛酸電(dian)(dian)池的(de)1／5左右，鋰電(dian)(dian)池電(dian)(dian)動自(zi)行車(che)最大(da)優點是(shi)壽(shou)命(ming)長。

聲(sheng)明：說鋰電(dian)池(chi)價(jia)格貴(gui)的只是看到表面，其實仔細(xi)算(suan)算(suan)費用(yong)和鉛酸(suan)(suan)蓄電(dian)池(chi)是差不多的，目(mu)前一般鋰電(dian)池(chi)保(bao)2年，鉛酸(suan)(suan)蓄電(dian)池(chi)保(bao)1年。

2、鋰電池具有免激活特性

在(zai)使用(yong)(yong)(yong)鋰(li)(li)電(dian)(dian)池(chi)中應注意(yi)的(de)是(shi)，電(dian)(dian)池(chi)放(fang)置(zhi)一(yi)段時(shi)間后則進入休眠(mian)狀態，此時(shi)容量(liang)低于正(zheng)常(chang)(chang)值，使用(yong)(yong)(yong)時(shi)間亦隨之(zhi)縮短。但鋰(li)(li)電(dian)(dian)池(chi)很容易激(ji)(ji)活，只要(yao)(yao)經過3—5次正(zheng)常(chang)(chang)的(de)充放(fang)電(dian)(dian)循(xun)環就可激(ji)(ji)活電(dian)(dian)池(chi)，恢(hui)復正(zheng)常(chang)(chang)容量(liang)。由于鋰(li)(li)電(dian)(dian)池(chi)本身的(de)特性，決(jue)定(ding)了它幾乎沒有記憶效應 。因此用(yong)(yong)(yong)戶新(xin)鋰(li)(li)電(dian)(dian)池(chi)在(zai)激(ji)(ji)活過程中，是(shi)不需要(yao)(yao)特別(bie)的(de)方法和設備的(de)。

3、無記憶效應

消費者(zhe)(zhe)在給鉛酸蓄電(dian)池(chi)(chi)，鎳電(dian)池(chi)(chi)充電(dian)時，一(yi)直都擔心(xin)電(dian)池(chi)(chi)發生記憶效應，等用了鋰電(dian)池(chi)(chi)，大家(jia)都可以松(song)下一(yi)口氣，鋰電(dian)池(chi)(chi)不帶記憶效應。要是還有消費者(zhe)(zhe)不知道如何給鋰電(dian)池(chi)(chi)充電(dian)，那不妨看看下面(mian)的(de)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)價格(ge)普遍比鉛酸電(dian)池電(dian)動(dong)車(che)高出幾百元到(dao)一千元，因(yin)此在市面上很難(nan)得到(dao)消費者顧客的(de)認可。鋰電(dian)池輕巧、環保，廢棄后不會產生環境污染，一旦應用技術(shu)成熟，市場銷(xiao)量加(jia)大，鋰電(dian)池電(dian)動(dong)自(zi)行車(che)的(de)價格(ge)才會有(you)所降下來。

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)(zai)(zai)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)滿(man)后(hou)(hou)都(dou)會自動停充(chong)(chong)(chong)，并(bing)不存在(zai)(zai)(zai)鎳電(dian)(dian)(dian)充(chong)(chong)(chong)電(dian)(dian)(dian)器所(suo)謂(wei)的(de)持續10幾(ji)小時的(de)“涓流”充(chong)(chong)(chong)電(dian)(dian)(dian)。也就是(shi)說，如果你的(de)鋰電(dian)(dian)(dian)池(chi)在(zai)(zai)(zai)充(chong)(chong)(chong)滿(man)后(hou)(hou)，放在(zai)(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)器上(shang)也是(shi)白(bai)充(chong)(chong)(chong)。而我(wo)們誰都(dou)無法保證(zheng)電(dian)(dian)(dian)池(chi)的(de)充(chong)(chong)(chong)放電(dian)(dian)(dian)保護電(dian)(dian)(dian)路的(de)特(te)性(xing)永不變化和質量的(de)萬無一(yi)(yi)失(shi)，所(suo)以你的(de)電(dian)(dian)(dian)池(chi)將(jiang)長期處在(zai)(zai)(zai)危險的(de)邊(bian)緣徘徊。這也是(shi)我(wo)們反對(dui)長充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)另一(yi)(yi)個理由。

此外(wai)在某(mou)些(xie)電(dian)(dian)(dian)動車上，充電(dian)(dian)(dian)超(chao)過一(yi)定的(de)(de)時(shi)間(jian)后，如果不去取下充電(dian)(dian)(dian)器，這(zhe)時(shi)系統不僅不停(ting)止(zhi)充電(dian)(dian)(dian)，還(huan)將(jiang)開始放電(dian)(dian)(dian)-充電(dian)(dian)(dian)循環。也許(xu)這(zhe)種做法的(de)(de)廠商(shang)自有其目的(de)(de)，但顯然對電(dian)(dian)(dian)池的(de)(de)壽命而言是不利的(de)(de)。所(suo)以(yi)在購買鋰電(dian)(dian)(dian)池電(dian)(dian)(dian)動車后，要咨詢企業或者經銷(xiao)商(shang)，做好鋰電(dian)(dian)(dian)池維護工作。

3、鋰電池動力性有待提高

鋰(li)電(dian)(dian)池比(bi)起鉛(qian)酸蓄電(dian)(dian)池在充放電(dian)(dian)方面耐波動的能力(li)差得多，對于目前大功率車來說不能有效采用(yong)鋰(li)電(dian)(dian)的一(yi)大癥狀(zhuang)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

鋰電池的安全性仍(reng)(reng)有(you)待提(ti)高。鋰(li)電(dian)(dian)池起(qi)火、燃(ran)燒甚(shen)至(zhi)(zhi)爆(bao)炸(zha)的隱患目(mu)前仍(reng)(reng)無法完全消除。車輛發(fa)生(sheng)碰撞可能導致(zhi)(zhi)電(dian)(dian)池正負極材料沖(chong)破隔膜，剎車時能量快速(su)回充至(zhi)(zhi)電(dian)(dian)池時瞬(shun)間的超(chao)高電(dian)(dian)流(liu)等原因都會導致(zhi)(zhi)電(dian)(dian)池發(fa)生(sheng)短路、溫(wen)度(du)升高，引起(qi)燃(ran)燒甚(shen)至(zhi)(zhi)爆(bao)炸(zha)。起(qi)火的原因是碰撞、短路導致(zhi)(zhi)鋰(li)離(li)(li)子(zi)析出，與(yu)(yu)空(kong)氣(qi)接觸(chu)會發(fa)生(sheng)起(qi)火、燃(ran)燒。另外(wai)，鋰(li)離(li)(li)子(zi)電(dian)(dian)池的電(dian)(dian)解(jie)液是有(you)機電(dian)(dian)解(jie)液，這些物(wu)質(zhi)與(yu)(yu)空(kong)氣(qi)接觸(chu)后更容易起(qi)火燃(ran)燒。
