電(dian)(dian)(dian)動(dong)汽車(che)已(yi)經(jing)走向(xiang)人們的(de)生活,但(dan)是(shi)電(dian)(dian)(dian)動(dong)汽車(che)電(dian)(dian)(dian)池問題一直都存在。目(mu)前市面上的(de)電(dian)(dian)(dian)動(dong)汽車(che)主要分為兩種類型,一種是(shi)鉛酸(suan)電(dian)(dian)(dian)池組車(che)型,另(ling)一種則是(shi)鋰電(dian)(dian)(dian)池組車(che)型。小(xiao)編經(jing)常會(hui)在網上看到一些網友問到底是(shi)購買鋰電(dian)(dian)(dian)池電(dian)(dian)(dian)動(dong)汽車(che)還是(shi)鉛酸(suan)電(dian)(dian)(dian)池電(dian)(dian)(dian)動(dong)車(che);二者有(you)何區別;哪(na)種相對更好些等等問題。
電動汽車專用蓄電池
造成這一困擾的的主要原因有兩點:
第(di)一(yi)是價格(ge),鋰電池(chi)電動車(che)的(de)價格(ge)一(yi)般(ban)都是鉛(qian)(qian)酸電池(chi)電動車(che)價格(ge)的(de)2~3倍,所以鋰電池(chi)電動車(che)的(de)價格(ge)比鉛(qian)(qian)酸要高不少(shao)價錢;
第二點則(ze)是電池性能(neng)問題,網上(shang)有(you)人(ren)調(diao)侃道:“鋰(li)電池電動車(che)太貴(gui)買不起,鉛(qian)酸電池電動車(che)太重搬不動”。
鋰(li)電(dian)池(chi)(chi)(chi)在各個性能(neng)方面比鉛(qian)(qian)酸(suan)電(dian)池(chi)(chi)(chi)更優(you)(you)越是毫無(wu)疑問的,目前最常見的就是磷酸(suan)鐵鋰(li)電(dian)池(chi)(chi)(chi),該(gai)(gai)電(dian)池(chi)(chi)(chi)不(bu)像鉛(qian)(qian)酸(suan)電(dian)池(chi)(chi)(chi)有記憶效(xiao)應,在經過1600多次充(chong)(chong)電(dian)后,該(gai)(gai)電(dian)池(chi)(chi)(chi)的的存儲能(neng)力(li)依然能(neng)夠達到(dao)85%,鋰(li)電(dian)池(chi)(chi)(chi)與鉛(qian)(qian)酸(suan)電(dian)池(chi)(chi)(chi)相比,鋰(li)電(dian)池(chi)(chi)(chi)具有重(zhong)量(liang)(liang)輕、比容量(liang)(liang)大(da)、循環使用(yong)壽命長(chang)等(deng)優(you)(you)點(dian),它(ta)作為低速電(dian)動汽車(che)車(che)載動力(li)電(dian)源,不(bu)僅(jin)輕量(liang)(liang)便攜方便充(chong)(chong)電(dian),而且有助于(yu)整車(che)產品之(zhi)“輕量(liang)(liang)化(hua)及簡約化(hua)”設計。
鉛酸(suan)(suan)電(dian)(dian)池的電(dian)(dian)極主(zhu)要(yao)由鉛及其氧化(hua)(hua)物制(zhi)成(cheng),電(dian)(dian)解液是硫酸(suan)(suan)溶(rong)液。鉛酸(suan)(suan)電(dian)(dian)池荷(he)電(dian)(dian)狀(zhuang)態下(xia),正極主(zhu)要(yao)成(cheng)分為(wei)二氧化(hua)(hua)鉛,負(fu)極主(zhu)要(yao)成(cheng)分為(wei)鉛;放電(dian)(dian)狀(zhuang)態下(xia),正負(fu)極的主(zhu)要(yao)成(cheng)分均為(wei)硫酸(suan)(suan)鉛。鉛酸(suan)(suan)電(dian)(dian)池因為(wei)有記憶效應(ying),在重疊500多次的時候,該電(dian)(dian)池的存(cun)儲能力就會大大下(xia)降。
兩種電(dian)池除了都是(shi)屬于儲能(neng)裝置,其他都不怎么一(yi)樣。鉛(qian)酸(suan)電(dian)池更(geng)安全(quan),更(geng)便宜,但是(shi)能(neng)量(liang)密度比鋰電(dian)低,所以鉛(qian)酸(suan)電(dian)池的(de)體(ti)積(ji)就(jiu)大些。即便這樣,高價格的(de)鋰電(dian)池電(dian)動(dong)車仍(reng)然不能(neng)完全(quan)取代鉛(qian)酸(suan)電(dian)池電(dian)動(dong)車。
現(xian)階段(duan)而言(yan),在電(dian)(dian)池(chi)(chi)(儲能)技術研究尚未能獲得突破性進展(zhan),即(ji)“低成本、高性能”電(dian)(dian)池(chi)(chi)尚未投入商品化實際應用之前(qian)(qian),我們可以(yi)將現(xian)有的鉛酸電(dian)(dian)池(chi)(chi)和鋰電(dian)(dian)池(chi)(chi)的優(you)良特性聯合起來轉(zhuan)型升級(ji),作為目前(qian)(qian)以(yi)至今(jin)后(hou)一段(duan)時期內之主要研究課題。相(xiang)信這對(dui)將來低速電(dian)(dian)動汽車(che),甚至整個電(dian)(dian)動汽車(che)行業的發展(zhan)有著更明朗的方(fang)向。
就目(mu)前(qian)“鋰電(dian)車(che)”普及率而言,遠低于(yu)采用(yong)“鉛酸(suan)電(dian)池”車(che)型產品,其原因(yin)在于(yu),目(mu)前(qian)鋰電(dian)池成(cheng)本仍(reng)相對偏高(gao)。因(yin)而,在現有“鋰電(dian)車(che)”產品設計中,多(duo)采用(yong)減少鋰電(dian)池的容量配(pei)置,來相應降(jiang)低整車(che)實施(shi)成(cheng)本。對于(yu)上(shang)述相關問題的探討,希(xi)望能夠(gou)讓更多的(de)消(xiao)費(fei)者(zhe)認(ren)清(qing) “鉛酸電(dian)動和鋰電(dian)池(chi)”兩(liang)者(zhe)的(de)分析(xi)。
電動汽車使用中有可能出現這(zhe)樣那樣的問(wen)題,針(zhen)對(dui)日常使用中電瓶會出現的一些問(wen)題進行答(da)疑解惑。
一直以來電(dian)(dian)瓶作為“方便電(dian)(dian)源”一直被人們(men)所廣泛使用特別是運用,特別是在這(zhe)些新能源電(dian)(dian)動汽車的運用上,但是人們(men)又對(dui)電(dian)(dian)池(chi)的知(zhi)(zhi)識卻了解甚少(shao)。安全大于(yu)一切,所以了解相(xiang)關知(zhi)(zhi)識非常必要。
“過充”導致蓄電池壞損
“過(guo)充”就是過(guo)量給電(dian)(dian)動(dong)汽車的蓄電(dian)(dian)瓶充電(dian)(dian)而產(chan)生的一種對(dui)蓄電(dian)(dian)瓶化(hua)學(xue)和物理性能起到(dao)破壞(huai)作用的現象。
電(dian)(dian)動汽車充(chong)(chong)電(dian)(dian)器在充(chong)(chong)電(dian)(dian)時是同時給串聯(lian)而成的(de)(de)(de)蓄電(dian)(dian)瓶(ping)組充(chong)(chong)電(dian)(dian),電(dian)(dian)壓(ya)(ya)較高(gao)的(de)(de)(de)電(dian)(dian)瓶(ping)會先充(chong)(chong)滿電(dian)(dian),電(dian)(dian)壓(ya)(ya)較低的(de)(de)(de)蓄電(dian)(dian)瓶(ping)會后(hou)充(chong)(chong)滿甚至一(yi)直在充(chong)(chong)電(dian)(dian),由(you)于充(chong)(chong)電(dian)(dian)器是以總(zong)體電(dian)(dian)壓(ya)(ya)為充(chong)(chong)電(dian)(dian)或停(ting)止充(chong)(chong)電(dian)(dian)設定的(de)(de)(de),因(yin)此,先充(chong)(chong)滿電(dian)(dian)的(de)(de)(de)蓄電(dian)(dian)瓶(ping)就(jiu)會處在“過充(chong)(chong)”狀態。“壓(ya)(ya)差”小(xiao)時對電(dian)(dian)瓶(ping)影(ying)響不(bu)大(da),“壓(ya)(ya)差”大(da)時,經常“過充(chong)(chong)”的(de)(de)(de)電(dian)(dian)瓶(ping)池一(yi)樣會產生電(dian)(dian)解液熱(re)反(fan)應加劇,直至把這節蓄電(dian)(dian)瓶(ping)充(chong)(chong)壞。
“虧電”導致電瓶壞損
低速(su)電(dian)(dian)(dian)動汽車所說的“虧電(dian)(dian)(dian)”是電(dian)(dian)(dian)瓶(ping)電(dian)(dian)(dian)量不足、電(dian)(dian)(dian)壓(ya)(ya)偏低時(shi)強行過量放電(dian)(dian)(dian)產生的一(yi)種破(po)壞(huai)蓄電(dian)(dian)(dian)瓶(ping)極板涂層的現象。要知道,任何車載(zai)電(dian)(dian)(dian)器(qi)(qi)的工(gong)作(zuo)電(dian)(dian)(dian)壓(ya)(ya)都有一(yi)個標準范(fan)圍,超(chao)過這個范(fan)圍電(dian)(dian)(dian)器(qi)(qi)容易(yi)短路甚至(zhi)燒毀,低于這個范(fan)圍電(dian)(dian)(dian)器(qi)(qi)無法啟動或正(zheng)常工(gong)作(zuo),甚至(zhi)影響使用(yong)壽命,車載(zai)電(dian)(dian)(dian)器(qi)(qi)和蓄電(dian)(dian)(dian)瓶(ping)都是這樣。
大電流放電使電瓶壞損
低速(su)(su)電(dian)(dian)(dian)動(dong)汽(qi)車(che)(che)在(zai)啟(qi)動(dong)、加速(su)(su)的(de)(de)(de)瞬(shun)間電(dian)(dian)(dian)流(liu)(liu)(liu)很大,一般會(hui)達到20A—50A,根(gen)據低速(su)(su)電(dian)(dian)(dian)動(dong)汽(qi)車(che)(che)電(dian)(dian)(dian)機功率(lv)的(de)(de)(de)大小,正常(chang)的(de)(de)(de)放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)(liu)一般控制在(zai)10A以內(nei)為好。過(guo)(guo)載(zai)就(jiu)(jiu)(jiu)是電(dian)(dian)(dian)動(dong)汽(qi)車(che)(che)行駛(shi)中負載(zai)超重,如(ru)過(guo)(guo)量(liang)的(de)(de)(de)載(zai)貨、載(zai)人等,過(guo)(guo)載(zai)會(hui)使蓄電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)負荷加大,長(chang)時間的(de)(de)(de)大電(dian)(dian)(dian)流(liu)(liu)(liu)放電(dian)(dian)(dian),會(hui)直(zhi)接(jie)影(ying)響極(ji)板(ban)涂層(ceng),加快極(ji)板(ban)軟化的(de)(de)(de)過(guo)(guo)程(cheng)。 還(huan)有就(jiu)(jiu)(jiu)是路(lu)況不好也(ye)(ye)會(hui)使電(dian)(dian)(dian)動(dong)車(che)(che)頻繁的(de)(de)(de)剎車(che)(che)和啟(qi)動(dong)。如(ru)坑洼、紅燈、路(lu)障等,都是造(zao)成大電(dian)(dian)(dian)流(liu)(liu)(liu)放電(dian)(dian)(dian)的(de)(de)(de)因素(su)。因為電(dian)(dian)(dian)機功率(lv)越(yue)(yue)大,放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)(liu)也(ye)(ye)就(jiu)(jiu)(jiu)越(yue)(yue)大,對電(dian)(dian)(dian)瓶的(de)(de)(de)損傷也(ye)(ye)就(jiu)(jiu)(jiu)越(yue)(yue)大。
極板硫化導電瓶壞損
在極板上生成白色堅硬的(de)硫(liu)(liu)(liu)酸(suan)鉛結晶,充電時又非常難于轉化為活性物質的(de)硫(liu)(liu)(liu)酸(suan)鉛,這就是硫(liu)(liu)(liu)酸(suan)鹽(yan)化,簡稱“硫(liu)(liu)(liu)化”。這種硫(liu)(liu)(liu)酸(suan)鉛的(de)導電性不良、電阻大,溶(rong)解(jie)度(du)和(he)溶(rong)解(jie)速度(du)又很小,充電時恢復困難。因(yin)而成為容(rong)量降低和(he)壽命縮短的(de)原因(yin)。硫(liu)(liu)(liu)化是蓄電瓶容(rong)量減少的(de)主要癥結。
介紹完鋰電池和鉛酸蓄電池,小編要提醒大家一下:除以上蓄電池壞損的主因外,電池質量差、極板脫落、電解液外漏、失水、外殼破損、電瓶接線端子斷裂等也是蓄電池壞損的原因,還有一些連我們都沒發覺的潛在因素。上海施能電器(qi)設備有限(xian)公司始建于1984年,上海市高新技術企業,中國工業車輛優秀配套供應商,上海電器行業名優產品,主要生產工頻系列充電機,高頻系列充電機,鋰電池充電機,系列放電機,系列充放電機等電器產品。
