1、鋰電池重量輕體積小 鋰(li)電(dian)(dian)池(chi)電(dian)(dian)動(dong)車目(mu)前品牌多樣化,在動(dong)力性能方面和(he)鉛酸電(dian)(dian)池(chi)差不多,充電(dian)(dian)6~8小(xiao)時,根(gen)據(ju)電(dian)(dian)池(chi)容量不同可跑(pao)30~45公里,重量只(zhi)有(you)鉛酸電(dian)(dian)池(chi)的1/5左右,而且目(mu)前一般鋰(li)電(dian)(dian)池(chi)保2年,鉛酸蓄電(dian)(dian)池(chi)保1年。
2、鋰電池具有免激活特性 鋰電池(chi)(chi)很(hen)容(rong)易激活(huo),只要(yao)經過(guo)3-5次正(zheng)常(chang)的(de)充放電循環(huan)就可激活(huo)電池(chi)(chi),恢(hui)復正(zheng)常(chang)容(rong)量。由于鋰電池(chi)(chi)本身的(de)特性,決定(ding)了(le)它幾乎沒(mei)有(you)記(ji)憶效應 。因此用戶(hu)新鋰電池(chi)(chi)在(zai)激活(huo)過(guo)程中,是不需要(yao)特別的(de)方法和設備的(de)。
3、鋰電池帶記憶效應 在給鉛酸(suan)蓄電(dian)(dian)(dian)(dian)池(chi),鎳(nie)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)時,一直都擔(dan)心(xin)電(dian)(dian)(dian)(dian)池(chi)發生記憶效應(ying),而電(dian)(dian)(dian)(dian)動自行車鋰電(dian)(dian)(dian)(dian)池(chi)不帶記憶效應(ying),可以放心(xin)充電(dian)(dian)(dian)(dian)而不用擔(dan)心(xin)電(dian)(dian)(dian)(dian)池(chi)之前的充電(dian)(dian)(dian)(dian)用電(dian)(dian)(dian)(dian)情(qing)況。
4、鋰電池循環壽命長 鋰離子電(dian)(dian)(dian)池以1C倍率進行充、放電(dian)(dian)(dian),其(qi)循(xun)環壽(shou)命大(da)于(yu)等(deng)于(yu)500次,第500次時的電(dian)(dian)(dian)容(rong)量,大(da)于(yu)標(biao)稱(cheng)銅梁70%。而鉛酸電(dian)(dian)(dian)池即使以0.5放電(dian)(dian)(dian),以0.15C以充電(dian)(dian)(dian),其(qi)循(xun)環壽(shou)命小于(yu)等(deng)于(yu)350次,電(dian)(dian)(dian)容(rong)量小于(yu)等(deng)于(yu)60%。
5、工作溫度范圍寬 電動自行車鋰離子電池可在(zai)(zai)-25度(du)到55度(du)范(fan)圍(wei)內工作,其電容量(liang)可達(da)標(biao)稱容量(liang)的70%,而(er)鉛酸電池只能在(zai)(zai)10度(du)到40度(du)范(fan)圍(wei)內工作,在(zai)(zai)-25度(du)時不能正常工作。
6、鋰電池充電時間短,綠色環保 由于(yu)電(dian)動自行車鋰離子電(dian)池(chi)具有可大電(dian)流充(chong)電(dian)的特性,因此充(chong)電(dian)時間只要4-5小(xiao)時,而鉛酸電(dian)池(chi)則需要8至10小(xiao)時。無對環境有害的重金屬鉛,屬于(yu)高環保型的產品。
1、低(di)于市(shi)場平均(jun)批發價的電(dian)池(chi)堅決不買。
2、沒經(jing)過2年以上的市(shi)場考驗的產品。
3、沒有電(dian)動(dong)車(che)(che)廠家配車(che)(che)的(de)電(dian)池堅決(jue)不(bu)買(mai)。
4、高價電池(chi),如(ru)果不(bu)(bu)是大廠生產的(de),堅決不(bu)(bu)買(mai)。
5、改變國家(jia)標準尺(chi)寸的電(dian)池堅(jian)決(jue)不買。
6、5A放(fang)電(dian),30秒時電(dian)壓高于12.68V的堅決不買(mai),90%以(yi)上是短命(ming)電(dian)池(chi)。
用多久:電(dian)(dian)(dian)動車鋰電(dian)(dian)(dian)池(chi)(chi)(chi)能用(yong)幾年?相信絕(jue)大部分消費者都聽說(shuo)過(guo)(guo),鋰電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)壽(shou)命是(shi)“500次(ci)(ci)(ci)”,500次(ci)(ci)(ci)充(chong)(chong)放電(dian)(dian)(dian),超過(guo)(guo)這個次(ci)(ci)(ci)數(shu),電(dian)(dian)(dian)池(chi)(chi)(chi)就“壽(shou)終正寢”了(le),許(xu)多朋友為了(le)能夠延長(chang)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)壽(shou)命,每次(ci)(ci)(ci)都在電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)量完全耗(hao)盡(jin)時才進行充(chong)(chong)電(dian)(dian)(dian),這樣對電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)壽(shou)命真的(de)(de)(de)有延長(chang)作(zuo)用(yong)嗎?答案(an)是(shi)否定的(de)(de)(de)。鋰電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)壽(shou)命是(shi)“500次(ci)(ci)(ci)”,指的(de)(de)(de)不是(shi)充(chong)(chong)電(dian)(dian)(dian)的(de)(de)(de)次(ci)(ci)(ci)數(shu),而是(shi)一個充(chong)(chong)放電(dian)(dian)(dian)的(de)(de)(de)周期。
一(yi)(yi)(yi)個充(chong)電(dian)(dian)(dian)(dian)周期(qi)(qi)意(yi)味著電(dian)(dian)(dian)(dian)池(chi)的所有電(dian)(dian)(dian)(dian)量由(you)滿用到空,再由(you)空充(chong)到滿的過(guo)程,這并不(bu)等同于充(chong)一(yi)(yi)(yi)次(ci)電(dian)(dian)(dian)(dian)。比(bi)如(ru)說,一(yi)(yi)(yi)塊鋰電(dian)(dian)(dian)(dian)在第一(yi)(yi)(yi)天只用了一(yi)(yi)(yi)半的電(dian)(dian)(dian)(dian)量,然后(hou)又為(wei)它充(chong)電(dian)(dian)(dian)(dian)慢電(dian)(dian)(dian)(dian)。如(ru)果第二天還如(ru)此,即用一(yi)(yi)(yi)半就充(chong),總共兩次(ci)充(chong)電(dian)(dian)(dian)(dian)下來,這只能(neng)算作一(yi)(yi)(yi)個充(chong)電(dian)(dian)(dian)(dian)周期(qi)(qi),而不(bu)是兩個。因此,通常可能(neng)要經過(guo)好幾次(ci)充(chong)電(dian)(dian)(dian)(dian)才完(wan)成(cheng)一(yi)(yi)(yi)個周期(qi)(qi)。每完(wan)成(cheng)一(yi)(yi)(yi)個充(chong)電(dian)(dian)(dian)(dian)周期(qi)(qi),電(dian)(dian)(dian)(dian)池(chi)容量就會減少一(yi)(yi)(yi)點。
不過,這個(ge)電(dian)量(liang)(liang)較少(shao)幅度非常小,高品(pin)(pin)質(zhi)的電(dian)池(chi)充過多次周期(qi)后(hou),仍(reng)然(ran)會保留原始容(rong)量(liang)(liang)的80%,很多鋰電(dian)供(gong)電(dian)產品(pin)(pin)在經過兩三(san)年(nian)后(hou)仍(reng)然(ran)照常使(shi)用。當然(ran),鋰電(dian)壽命到了最終后(hou)仍(reng)是(shi)需要(yao)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(yu)實際生活的(de)各(ge)種影響,特別(bie)是充電時(shi)的(de)放電深度不是恒(heng)定的(de),所以“500個充電周期(qi)”只能作為參考電池壽(shou)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(xiao)時”的(de)誤區。殊(shu)不知,如果您如此(ci)的(de)使(shi)鋰(li)電(dian)池(chi)過度(du)充電(dian)或(huo)過度(du)放電(dian),非但不能使(shi)電(dian)動車鋰(li)電(dian)池(chi)壽命延(yan)長,反而會縮(suo)短。那么如何(he)正確(que)使(shi)用鋰(li)電(dian)池(chi)呢?
即使(shi)您(nin)的電(dian)動車鋰(li)電(dian)池充一次電(dian)可以(yi)使(shi)用2到3天(tian),還是建議您每(mei)天(tian)都充電(dian)。因為使(shi)用(yong)后(hou)的鋰電(dian)池處于淺循環(huan)狀(zhuang)態,每(mei)天(tian)都充電(dian)會使(shi)電(dian)動(dong)車鋰電(dian)池的壽命延長(chang)。
因為(wei)鋰(li)電(dian)(dian)池在放電(dian)(dian)以后,會進入硫(liu)化過程,如果(guo)及時充電(dian)(dian),就可以清除不嚴重(zhong)的硫(liu)化。所以,鋰(li)電(dian)(dian)池在使用完了以后要盡早的充電(dian)(dian),盡可能使電(dian)(dian)池電(dian)(dian)量處于(yu)飽滿狀態。
一(yi)般(ban),在沒有把握的(de)(de)(de)時候不要隨(sui)意更換(huan)充電器。另外,不要去掉控制器的(de)(de)(de)限速,去掉控制器的(de)(de)(de)限速后(hou),雖(sui)然可以提高一(yi)些車(che)的(de)(de)(de)速度(du),但會降低電池(chi)的(de)(de)(de)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(yi)”性,影(ying)響其續行(xing)里程,同時也損耗電(dian)池(chi)使(shi)用壽命。充電(dian)時先插電(dian)池(chi)插頭(tou),再(zai)插電(dian)源插頭(tou)。充電(dian)結(jie)束(shu),先拔電(dian)源插頭(tou),再(zai)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(er)且溫度過低時(shi)(shi)要盡量縮短電(dian)動(dong)車的使(shi)用(yong)(yong)時(shi)(shi)間,并應及時(shi)(shi)進行(xing)充(chong)電(dian)。如果不準備(bei)在冬季使(shi)用(yong)(yong)電(dian)瓶車,電(dian)池不要一直(zhi)放到來(lai)年使(shi)用(yong)(yong)時(shi)(shi)再充(chong)電(dian),而(er)應該是每隔1個月給(gei)電池充1次(ci)電(dian)(dian)(dian),以保證(zheng)鉛酸電(dian)(dian)(dian) 池的儲電(dian)(dian)(dian)能(neng)力,同時避免酸液外溢損壞電(dian)(dian)(dian)池。維(wei)修(xiu)人員說(shuo)保養(yang)電(dian)(dian)(dian)瓶就記住要勤充電(dian)(dian)(dian)、多(duo)助力。
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。
