電(dian)(dian)動汽(qi)車(che)(che)(che)已經(jing)走向(xiang)人們的生活(huo)，但是(shi)(shi)(shi)電(dian)(dian)動汽(qi)車(che)(che)(che)電(dian)(dian)池(chi)問(wen)題(ti)一(yi)直都存(cun)在。目前市面上(shang)的電(dian)(dian)動汽(qi)車(che)(che)(che)主要分(fen)為兩種類型，一(yi)種是(shi)(shi)(shi)鉛(qian)酸(suan)(suan)電(dian)(dian)池(chi)組(zu)車(che)(che)(che)型，另一(yi)種則是(shi)(shi)(shi)鋰(li)電(dian)(dian)池(chi)組(zu)車(che)(che)(che)型。小(xiao)編經(jing)常會在網上(shang)看到一(yi)些(xie)網友問(wen)到底是(shi)(shi)(shi)購買鋰(li)電(dian)(dian)池(chi)電(dian)(dian)動汽(qi)車(che)(che)(che)還是(shi)(shi)(shi)鉛(qian)酸(suan)(suan)電(dian)(dian)池(chi)電(dian)(dian)動車(che)(che)(che)；二者有何區別；哪(na)種相對更好些(xie)等等問(wen)題(ti)。
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)一是價格(ge)(ge)，鋰電池電動車(che)(che)的價格(ge)(ge)一般都是鉛(qian)酸電池電動車(che)(che)價格(ge)(ge)的2~3倍(bei)，所以鋰電池電動車(che)(che)的價格(ge)(ge)比鉛(qian)酸要(yao)高不少價錢；
第二點則是電(dian)池性能問題，網上有人調(diao)侃道：“鋰電(dian)池電(dian)動車(che)太貴買不起，鉛酸電(dian)池電(dian)動車(che)太重搬不動”。
鋰(li)電(dian)(dian)(dian)池(chi)(chi)在各個性能(neng)方(fang)面比(bi)鉛酸電(dian)(dian)(dian)池(chi)(chi)更優越是毫無疑(yi)問的，目前(qian)最常見的就是磷(lin)酸鐵(tie)鋰(li)電(dian)(dian)(dian)池(chi)(chi)，該(gai)電(dian)(dian)(dian)池(chi)(chi)不像鉛酸電(dian)(dian)(dian)池(chi)(chi)有記(ji)憶效應，在經(jing)過(guo)1600多(duo)次(ci)充電(dian)(dian)(dian)后(hou)，該(gai)電(dian)(dian)(dian)池(chi)(chi)的的存儲能(neng)力(li)依然能(neng)夠達到85%，鋰(li)電(dian)(dian)(dian)池(chi)(chi)與鉛酸電(dian)(dian)(dian)池(chi)(chi)相比(bi)，鋰(li)電(dian)(dian)(dian)池(chi)(chi)具有重(zhong)量(liang)輕、比(bi)容量(liang)大、循環使用壽命長等優點(dian)，它作為低速電(dian)(dian)(dian)動汽車(che)車(che)載動力(li)電(dian)(dian)(dian)源，不僅輕量(liang)便(bian)攜方(fang)便(bian)充電(dian)(dian)(dian)，而(er)且有助于整(zheng)車(che)產品之(zhi)“輕量(liang)化及(ji)簡約(yue)化”設計。
鉛(qian)(qian)(qian)酸(suan)(suan)電池的電極(ji)(ji)主要(yao)由鉛(qian)(qian)(qian)及其氧(yang)化物制成(cheng)，電解液(ye)(ye)是硫酸(suan)(suan)溶液(ye)(ye)。鉛(qian)(qian)(qian)酸(suan)(suan)電池荷(he)電狀態下(xia)(xia)，正極(ji)(ji)主要(yao)成(cheng)分為(wei)二氧(yang)化鉛(qian)(qian)(qian)，負極(ji)(ji)主要(yao)成(cheng)分為(wei)鉛(qian)(qian)(qian)；放電狀態下(xia)(xia)，正負極(ji)(ji)的主要(yao)成(cheng)分均為(wei)硫酸(suan)(suan)鉛(qian)(qian)(qian)。鉛(qian)(qian)(qian)酸(suan)(suan)電池因為(wei)有記憶效應，在重疊(die)500多(duo)次的時候，該電池的存儲能力就會大大下(xia)(xia)降。
兩種電(dian)池除了(le)都是屬于儲能(neng)(neng)裝(zhuang)置，其他都不怎么一樣。鉛(qian)(qian)酸電(dian)池更安全，更便(bian)宜，但(dan)是能(neng)(neng)量密(mi)度比(bi)鋰(li)電(dian)低，所以鉛(qian)(qian)酸電(dian)池的(de)體積(ji)就大些。即便(bian)這樣，高價(jia)格的(de)鋰(li)電(dian)池電(dian)動車(che)仍然不能(neng)(neng)完全取(qu)代鉛(qian)(qian)酸電(dian)池電(dian)動車(che)。
現階段而言，在(zai)電(dian)(dian)池(chi)（儲能）技術研究尚未(wei)能獲得突破性(xing)(xing)進展，即“低成(cheng)本(ben)、高(gao)性(xing)(xing)能”電(dian)(dian)池(chi)尚未(wei)投(tou)入商品(pin)化(hua)實(shi)際應(ying)用之(zhi)前(qian)，我們可以(yi)將現有的鉛酸電(dian)(dian)池(chi)和鋰電(dian)(dian)池(chi)的優良(liang)特性(xing)(xing)聯合起來轉型升級，作為目前(qian)以(yi)至(zhi)今后一段時(shi)期內之(zhi)主要研究課題。相信(xin)這對將來低速(su)電(dian)(dian)動(dong)(dong)汽車，甚至(zhi)整(zheng)個(ge)電(dian)(dian)動(dong)(dong)汽車行業的發(fa)展有著更明朗(lang)的方向(xiang)。
就目前(qian)“鋰電車(che)(che)”普及率而言，遠低(di)于采用“鉛酸電池”車(che)(che)型產(chan)品(pin)，其原因(yin)在于，目前(qian)鋰電池成(cheng)本(ben)仍相(xiang)對(dui)偏高。因(yin)而，在現(xian)有“鋰電車(che)(che)”產(chan)品(pin)設計中，多采用減少鋰電池的容量配置，來相(xiang)應(ying)降(jiang)低(di)整車(che)(che)實施成(cheng)本(ben)。對(dui)于上述相(xiang)關問題的探討，希望(wang)能夠讓(rang)更(geng)多(duo)的(de)消費者認(ren)清 “鉛酸(suan)電動和(he)鋰(li)電池”兩者的(de)分析(xi)。
電動汽車使(shi)用中有可能(neng)出現(xian)這(zhe)樣那樣的(de)問題(ti)，針對日常使(shi)用中電瓶會出現(xian)的(de)一些問題(ti)進行答(da)疑(yi)解惑(huo)。
一直(zhi)以來電(dian)(dian)瓶作為“方便電(dian)(dian)源”一直(zhi)被人(ren)們所廣(guang)泛(fan)使用(yong)特別是運用(yong)，特別是在這(zhe)些(xie)新能源電(dian)(dian)動汽車(che)的運用(yong)上，但(dan)是人(ren)們又對電(dian)(dian)池的知識(shi)卻了解甚少。安全大(da)于一切，所以了解相關知識(shi)非常必要。
“過充”導致蓄電池壞損
“過充”就(jiu)是過量給電動(dong)汽車(che)的蓄電瓶充電而(er)產生的一種對蓄電瓶化學和(he)物(wu)理性能起到(dao)破壞作用的現象。
電(dian)(dian)(dian)(dian)(dian)動汽(qi)車充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時是同時給串聯(lian)而(er)成的(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)組充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)較高的(de)(de)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)會先(xian)充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)較低的(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)會后充(chong)(chong)滿(man)甚至(zhi)一(yi)直在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，由于(yu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器是以(yi)總體電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)為充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)或停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)設定的(de)(de)，因此，先(xian)充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)的(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)就會處在“過(guo)充(chong)(chong)”狀態。“壓(ya)(ya)(ya)差(cha)”小時對電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)影(ying)響不大，“壓(ya)(ya)(ya)差(cha)”大時，經常“過(guo)充(chong)(chong)”的(de)(de)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)池一(yi)樣會產生(sheng)電(dian)(dian)(dian)(dian)(dian)解液熱反應(ying)加劇，直至(zhi)把這節蓄(xu)電(dian)(dian)(dian)(dian)(dian)瓶(ping)(ping)(ping)充(chong)(chong)壞(huai)。
“虧電”導致電瓶壞損
低(di)速電(dian)動汽車所說的“虧電(dian)”是電(dian)瓶電(dian)量不(bu)足、電(dian)壓偏低(di)時(shi)強行過量放電(dian)產生的一種破壞蓄電(dian)瓶極(ji)板(ban)涂層的現象。要知道，任何車載電(dian)器(qi)的工作電(dian)壓都有一個標準范圍，超過這(zhe)個范圍電(dian)器(qi)容易短路甚至(zhi)燒毀，低(di)于這(zhe)個范圍電(dian)器(qi)無法啟動或正常工作，甚至(zhi)影(ying)響使(shi)用壽命(ming)，車載電(dian)器(qi)和蓄電(dian)瓶都是這(zhe)樣。
大電流放電使電瓶壞損
低(di)速電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽車在(zai)啟(qi)(qi)動(dong)(dong)、加(jia)速的(de)瞬間電(dian)(dian)(dian)(dian)(dian)流很大(da)(da)(da)，一(yi)般(ban)會達到20A—50A，根據低(di)速電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽車電(dian)(dian)(dian)(dian)(dian)機功率(lv)的(de)大(da)(da)(da)小，正(zheng)常的(de)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流一(yi)般(ban)控制在(zai)10A以內為好(hao)。過(guo)載(zai)就是(shi)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)汽車行(xing)駛(shi)中負(fu)載(zai)超重，如過(guo)量的(de)載(zai)貨、載(zai)人等(deng)(deng)，過(guo)載(zai)會使蓄電(dian)(dian)(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)(dian)(dian)負(fu)荷加(jia)大(da)(da)(da)，長時(shi)間的(de)大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)，會直接影響極板(ban)涂層，加(jia)快極板(ban)軟化的(de)過(guo)程。 還有就是(shi)路況不好(hao)也會使電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)車頻(pin)繁的(de)剎車和啟(qi)(qi)動(dong)(dong)。如坑洼、紅燈、路障等(deng)(deng)，都是(shi)造成大(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)的(de)因素(su)。因為電(dian)(dian)(dian)(dian)(dian)機功率(lv)越(yue)大(da)(da)(da)，放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流也就越(yue)大(da)(da)(da)，對電(dian)(dian)(dian)(dian)(dian)瓶的(de)損傷也就越(yue)大(da)(da)(da)。
極板硫化導電瓶壞損
在極板上生成白色堅硬的(de)(de)硫酸(suan)鉛結(jie)晶(jing)，充電(dian)(dian)時又非常難(nan)于轉化(hua)(hua)為(wei)活性物質的(de)(de)硫酸(suan)鉛，這就是硫酸(suan)鹽(yan)化(hua)(hua)，簡稱“硫化(hua)(hua)”。這種硫酸(suan)鉛的(de)(de)導電(dian)(dian)性不(bu)良、電(dian)(dian)阻大，溶解度和溶解速度又很小，充電(dian)(dian)時恢復困難(nan)。因而成為(wei)容量(liang)降(jiang)低和壽命(ming)縮短的(de)(de)原因。硫化(hua)(hua)是蓄(xu)電(dian)(dian)瓶容量(liang)減少的(de)(de)主要癥結(jie)。
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(dian)器(qi)設備有限(xian)公司始(shi)建于(yu)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。
