電動車鋰電池如何組裝
1、準備材料,包括不銹鋼電池盒,給電動車組裝的60V24AH鋰電池,鋰電池必須選用電動車動力電池。
2、將鋰電池20顆(ke)一串,共計8串。
3、8串(chuan)鋰電池(chi)并聯起(qi)來,用隔(ge)板和膠布(bu)做好絕緣。
4、膠布固定,串聯焊接保護線。
5、用熱縮(suo)膜把(ba)串(chuan)焊(han)好的鋰電池包裹(guo)絕(jue)緣(yuan),接保護板,做好絕(jue)緣(yuan),防止短路。
6、鋰(li)(li)電(dian)(dian)池短路危害(hai)很大,熱縮膜包裹完鋰(li)(li)電(dian)(dian)池后電(dian)(dian)動車(che)(che)鋰(li)(li)電(dian)(dian)池組裝就完成了,將其放入電(dian)(dian)動車(che)(che)即可。
電動車鋰電池使用注意事項
1、溫度
溫(wen)度對鋰(li)電(dian)(dian)池(chi)壽命也有較大的(de)影響,冰(bing)點(dian)以下(xia)環境有可能使鋰(li)電(dian)(dian)池(chi)在電(dian)(dian)動車(che)打開的(de)瞬間燒(shao)毀,而(er)過熱的(de)環境則會縮減電(dian)(dian)動車(che)電(dian)(dian)池(chi)的(de)容量,切記不可將(jiang)電(dian)(dian)動車(che)太陽底下(xia)暴曬。
2、大電流
比(bi)如(ru)18650電(dian)(dian)(dian)(dian)(dian)芯(xin)是3C放電(dian)(dian)(dian)(dian)(dian),你電(dian)(dian)(dian)(dian)(dian)動車(che)是8000W的(de),用的(de)電(dian)(dian)(dian)(dian)(dian)芯(xin)低(di)于你的(de)電(dian)(dian)(dian)(dian)(dian)動車(che)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流,這(zhe)樣會導致(zhi)鋰電(dian)(dian)(dian)(dian)(dian)池溫(wen)度(du)過高,電(dian)(dian)(dian)(dian)(dian)流過大(da)而(er)壽命(ming)變短(duan),還會出現鼓包(bao)報廢的(de)情況(kuang),如(ru)果你的(de)電(dian)(dian)(dian)(dian)(dian)動車(che)功率非(fei)常(chang)大(da),速度(du)非(fei)常(chang)快,建議(yi)選擇10C電(dian)(dian)(dian)(dian)(dian)流的(de)18650電(dian)(dian)(dian)(dian)(dian)芯(xin),這(zhe)樣選擇合適(shi)的(de)電(dian)(dian)(dian)(dian)(dian)芯(xin)顯然非(fei)常(chang)重要。
3、滿電存放
三元鋰電滿電是4.35V,目前市面上的保護板都是4.2V就截止充電,所以很多人買到電動車鋰電池都(dou)說沒有標稱的容量(liang)多,其實就是這(zhe)個原因,一般長(chang)時間存放電(dian)(dian)動車鋰(li)電(dian)(dian)池,充滿半分(fen)之(zhi)50的電(dian)(dian)視(shi)最(zui)好(hao)的,比如(ru)你買新(xin)手機,很多都(dou)是開機百分(fen)之(zhi)50的電(dian)(dian)量(liang)。
如果滿電(dian)存放(fang)時間長,會(hui)讓鋰(li)電(dian)池容(rong)量減少。磷酸鐵(tie)鋰(li)和鈦酸鋰(li)除外(wai),這兩(liang)種是可以滿電(dian)存放(fang)的,還需要注意的就是選擇(ze)品質較好的保護板,鋰(li)電(dian)池最大的禁忌就是過沖過放(fang),三元鋰(li)一(yi)次過放(fang)就報廢(fei),過沖必定鼓包也報廢(fei)。
電動車鉛酸蓄電池好還是鋰電池好
鉛酸蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)作(zuo)為電(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi),在(zai)設計上有它的(de)(de)優(you)勢(shi)。優(you)勢(shi)表現在(zai)它所提(ti)供(gong)的(de)(de)開(kai)路電(dian)(dian)(dian)源(yuan)比(bi)較(jiao)大(相比(bi)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi))來(lai)說。一(yi)個(ge)12V的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi),只需(xu)要做成(cheng)一(yi)個(ge)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi),而鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)在(zai)作(zuo)為動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)時(shi)可能(neng)需(xu)要串聯很多形成(cheng)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)組(zu)才可以。對(dui)于動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)設計來(lai)說,鉛酸蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)可以比(bi)較(jiao)容(rong)易的(de)(de)做到,而鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)則需(xu)要在(zai)設計,后期充(chong)電(dian)(dian)(dian),使用維護(hu)中遇到很多問題。從制造(zao)成(cheng)本上面來(lai)講,目前的(de)(de)動(dong)力(li)型(xing)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi),前者要抵,后者要高。但鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)是未來(lai)的(de)(de)發展趨勢(shi)。
