1、鋰電池重量輕體積小 鋰電(dian)(dian)池(chi)(chi)電(dian)(dian)動(dong)車目前品牌多(duo)樣化,在動(dong)力性能方面和鉛酸電(dian)(dian)池(chi)(chi)差不多(duo),充電(dian)(dian)6~8小時,根據電(dian)(dian)池(chi)(chi)容(rong)量不同可(ke)跑(pao)30~45公里(li),重量只有(you)鉛酸電(dian)(dian)池(chi)(chi)的1/5左右,而(er)且目前一(yi)般鋰電(dian)(dian)池(chi)(chi)保(bao)2年,鉛酸蓄(xu)電(dian)(dian)池(chi)(chi)保(bao)1年。
2、鋰電池具有免激活特性 鋰電(dian)池(chi)(chi)很容易(yi)激活(huo)(huo)(huo),只要經過(guo)(guo)3-5次(ci)正(zheng)常的充放電(dian)循環就可激活(huo)(huo)(huo)電(dian)池(chi)(chi),恢復正(zheng)常容量(liang)。由(you)于鋰電(dian)池(chi)(chi)本身(shen)的特性,決定(ding)了它幾乎(hu)沒有記(ji)憶效(xiao)應 。因此用戶新鋰電(dian)池(chi)(chi)在激活(huo)(huo)(huo)過(guo)(guo)程(cheng)中,是不需要特別(bie)的方(fang)法和設備的。
3、鋰電池帶記憶效應 在給鉛酸(suan)蓄電(dian)(dian)(dian)(dian)(dian)池,鎳(nie)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)時,一直都擔(dan)心(xin)電(dian)(dian)(dian)(dian)(dian)池發生記憶(yi)效應(ying),而電(dian)(dian)(dian)(dian)(dian)動自(zi)行(xing)車(che)鋰(li)電(dian)(dian)(dian)(dian)(dian)池不帶記憶(yi)效應(ying),可以放心(xin)充(chong)電(dian)(dian)(dian)(dian)(dian)而不用擔(dan)心(xin)電(dian)(dian)(dian)(dian)(dian)池之前的充(chong)電(dian)(dian)(dian)(dian)(dian)用電(dian)(dian)(dian)(dian)(dian)情況。
4、鋰電池循環壽命長 鋰離子(zi)電(dian)池以(yi)1C倍(bei)率進行充(chong)、放電(dian),其循(xun)環(huan)壽(shou)命(ming)大(da)(da)于等于500次,第500次時的電(dian)容量,大(da)(da)于標稱銅梁70%。而(er)鉛(qian)酸電(dian)池即使(shi)以(yi)0.5放電(dian),以(yi)0.15C以(yi)充(chong)電(dian),其循(xun)環(huan)壽(shou)命(ming)小于等于350次,電(dian)容量小于等于60%。
5、工作溫度范圍寬 電動自行車鋰離(li)子電池可在-25度到(dao)55度范(fan)圍內工(gong)(gong)作(zuo),其電容量可達標稱容量的70%,而鉛酸電池只能在10度到(dao)40度范(fan)圍內工(gong)(gong)作(zuo),在-25度時不(bu)能正常工(gong)(gong)作(zuo)。
6、鋰電池充電時間短,綠色環保 由(you)于電(dian)動自行車鋰離子電(dian)池具(ju)有可大電(dian)流充電(dian)的(de)特性(xing),因此充電(dian)時(shi)間只要4-5小時(shi),而鉛酸電(dian)池則需要8至10小時(shi)。無對環境有害的(de)重金屬(shu)鉛,屬(shu)于高環保(bao)型的(de)產品(pin)。
1、低于市場平(ping)均批(pi)發價的電池堅決(jue)不買。
2、沒經過2年以上(shang)的(de)(de)市場考(kao)驗的(de)(de)產品。
3、沒有(you)電動車(che)廠家配(pei)車(che)的(de)電池堅決不買。
4、高價電池,如果不是大廠生產的(de),堅決不買。
5、改(gai)變國家(jia)標準(zhun)尺寸的電池(chi)堅決不買。
6、5A放電,30秒時(shi)電壓高于12.68V的堅決不買(mai),90%以上是短命電池。
用多久:電(dian)(dian)(dian)(dian)動車鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)能用(yong)幾年?相(xiang)信絕大部分消(xiao)費者都聽說過,鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)命是“500次”,500次充放(fang)電(dian)(dian)(dian)(dian),超過這個次數,電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)就“壽(shou)終正寢”了(le),許多朋(peng)友為了(le)能夠延長電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)命,每(mei)次都在電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)量完全耗盡時(shi)才進行充電(dian)(dian)(dian)(dian),這樣對電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)命真的(de)(de)有延長作用(yong)嗎?答案(an)是否定的(de)(de)。鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽(shou)命是“500次”,指的(de)(de)不是充電(dian)(dian)(dian)(dian)的(de)(de)次數,而(er)是一個充放(fang)電(dian)(dian)(dian)(dian)的(de)(de)周期。
一(yi)個充(chong)(chong)(chong)電(dian)(dian)周(zhou)期(qi)(qi)意味著(zhu)電(dian)(dian)池的所有(you)電(dian)(dian)量(liang)由(you)滿(man)用(yong)到(dao)(dao)空(kong),再(zai)由(you)空(kong)充(chong)(chong)(chong)到(dao)(dao)滿(man)的過程,這(zhe)并不等同于(yu)充(chong)(chong)(chong)一(yi)次(ci)(ci)電(dian)(dian)。比如(ru)說,一(yi)塊(kuai)鋰電(dian)(dian)在第(di)一(yi)天只用(yong)了(le)一(yi)半的電(dian)(dian)量(liang),然后又(you)為它充(chong)(chong)(chong)電(dian)(dian)慢電(dian)(dian)。如(ru)果第(di)二天還(huan)如(ru)此(ci),即用(yong)一(yi)半就充(chong)(chong)(chong),總共兩次(ci)(ci)充(chong)(chong)(chong)電(dian)(dian)下來(lai),這(zhe)只能算作一(yi)個充(chong)(chong)(chong)電(dian)(dian)周(zhou)期(qi)(qi),而不是(shi)兩個。因此(ci),通常可能要經過好幾次(ci)(ci)充(chong)(chong)(chong)電(dian)(dian)才完(wan)成一(yi)個周(zhou)期(qi)(qi)。每完(wan)成一(yi)個充(chong)(chong)(chong)電(dian)(dian)周(zhou)期(qi)(qi),電(dian)(dian)池容(rong)量(liang)就會減(jian)少一(yi)點。
不過(guo),這個(ge)電量(liang)較少幅度非(fei)常小,高(gao)品質的電池充過(guo)多次周(zhou)期后(hou),仍(reng)然(ran)會保留(liu)原始容量(liang)的80%,很(hen)多鋰電供電產品在經過(guo)兩三年后(hou)仍(reng)然(ran)照常使用。當然(ran),鋰電壽命到了最終(zhong)后(hou)仍(reng)是需要更換的。而所謂500次,是指廠商在恒定的放電深度實現了625次左右的可充次數,達到了500個充電周期。由于實際生活的(de)各種影響,特別是充電(dian)(dian)時的(de)放電(dian)(dian)深度不是恒定的(de),所(suo)以“500個充電(dian)(dian)周(zhou)期”只能作為參(can)考電(dian)(dian)池(chi)壽命。
誤區:我們經常有“鋰電池電量用盡后再充電”或者是“鋰電池充滿后繼續沖,一定要充夠12小時”的誤區(qu)。殊不知,如(ru)果您如(ru)此的使鋰電(dian)池(chi)過度(du)充電(dian)或過度(du)放(fang)電(dian),非(fei)但不能(neng)使電(dian)動車鋰電(dian)池(chi)壽命延長,反而會縮短。那(nei)么如(ru)何正確使用鋰電(dian)池(chi)呢(ni)?
即使您的電動車(che)鋰電池充(chong)一(yi)次電可以使用(yong)2到3天(tian),還是建議您每天(tian)都充(chong)電(dian)。因為使用后的鋰電(dian)池(chi)(chi)處于淺(qian)循環狀(zhuang)態,每天(tian)都充(chong)電(dian)會使電(dian)動車鋰電(dian)池(chi)(chi)的壽命延長。
因(yin)為(wei)鋰電(dian)池在放電(dian)以后(hou),會進入硫(liu)化(hua)(hua)過程,如果及時充(chong)電(dian),就可(ke)以清除不嚴重的(de)硫(liu)化(hua)(hua)。所(suo)以,鋰電(dian)池在使(shi)用(yong)完了(le)以后(hou)要盡早的(de)充(chong)電(dian),盡可(ke)能使(shi)電(dian)池電(dian)量處于飽滿(man)狀態。
一般,在沒有(you)把(ba)握的時(shi)候不要隨意(yi)更換充(chong)電器(qi)。另外,不要去(qu)掉控制(zhi)器(qi)的限速(su),去(qu)掉控制(zhi)器(qi)的限速(su)后,雖然可以提高一些車的速(su)度,但會(hui)降(jiang)低(di)電池的使(shi)用(yong)壽命。
首先充電方面,經常不充滿電使用,電池將產生一種“記(ji)憶”性,影響其續行里程,同時(shi)也損(sun)耗(hao)電(dian)池(chi)使用壽命(ming)。充電(dian)時(shi)先插電(dian)池(chi)插頭(tou),再插電(dian)源插頭(tou)。充電(dian)結束,先拔電(dian)源插頭(tou),再拔電(dian)池(chi)插頭(tou)。
其次啟動電動車,避免大電流放電,減少載人行駛,爬坡時最好人力推行或助力騎行,否則對電池的損傷很大。如果車輛在露天或冷庫停放數周不用的時候,應卸下電池,存放在較為溫暖的房間內,以防電池結冰損壞。而且溫度過低時(shi)(shi)要盡量縮短電動(dong)車的使(shi)用(yong)時(shi)(shi)間,并應及時(shi)(shi)進(jin)行(xing)充電。如果不準備在冬(dong)季使(shi)用(yong)電瓶車,電池不要一直放到(dao)來(lai)年使(shi)用(yong)時(shi)(shi)再充電,而應該是每隔1個(ge)月給電池充1次電,以保(bao)證鉛酸電 池的儲電能力(li),同時避(bi)免酸液(ye)外(wai)溢損壞電池。維(wei)修人員說保(bao)養電瓶就記住要勤充(chong)電、多助力(li)。
在使用半年后最好到維修點做一個電池保養,適當補充電池的電解 液,調節好電解液的比重,并檢查其存電情況,保持蓄電池電解液的比重,必要時可以增加充電次數。同時,清潔電池的接線柱,并涂上專用油脂加以保護也很重 要,這可以保證電動車啟動時切實可靠,延長電池的壽命。
