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(dian)池(chi)20顆一串,共計8串。
3、8串鋰電池并聯起(qi)來,用(yong)隔板和膠布做好(hao)絕緣。
4、膠布固定(ding),串聯焊接保護線(xian)。
5、用熱縮膜把串焊好的鋰電池(chi)包裹絕緣,接(jie)保(bao)護(hu)板,做好絕緣,防(fang)止短路。
6、鋰電池短路危害很大,熱縮(suo)膜包裹完鋰電池后電動(dong)車鋰電池組裝就完成(cheng)了,將其放(fang)入電動(dong)車即可。
電動車鋰電池使用注意事項
1、溫度
溫(wen)度對(dui)鋰(li)電(dian)(dian)池壽命(ming)也有(you)較大(da)的影(ying)響,冰(bing)點以下環境有(you)可(ke)(ke)能(neng)使(shi)鋰(li)電(dian)(dian)池在(zai)電(dian)(dian)動(dong)車打開的瞬間(jian)燒毀,而過(guo)熱的環境則會縮減電(dian)(dian)動(dong)車電(dian)(dian)池的容量,切(qie)記不可(ke)(ke)將電(dian)(dian)動(dong)車太陽底下暴曬(shai)。
2、大電流
比如(ru)18650電(dian)(dian)芯是(shi)3C放電(dian)(dian),你電(dian)(dian)動(dong)車(che)是(shi)8000W的(de),用的(de)電(dian)(dian)芯低于你的(de)電(dian)(dian)動(dong)車(che)放電(dian)(dian)電(dian)(dian)流,這樣會導致(zhi)鋰(li)電(dian)(dian)池溫(wen)度過高,電(dian)(dian)流過大而壽(shou)命(ming)變短,還會出現鼓包(bao)報(bao)廢的(de)情況,如(ru)果你的(de)電(dian)(dian)動(dong)車(che)功率非常(chang)大,速度非常(chang)快,建(jian)議選(xuan)擇10C電(dian)(dian)流的(de)18650電(dian)(dian)芯,這樣選(xuan)擇合適的(de)電(dian)(dian)芯顯然非常(chang)重(zhong)要(yao)。
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說(shuo)沒有標(biao)稱的容(rong)量多,其實就是(shi)這個原因,一般長時間存放電動(dong)車鋰電池(chi),充滿(man)半分之50的電視最好(hao)的,比如你買(mai)新手機,很多都是(shi)開機百分之50的電量。
如果滿(man)(man)電存放(fang)(fang)(fang)時間長(chang),會讓鋰電池容量減少。磷酸鐵鋰和鈦酸鋰除外(wai),這兩種是(shi)可以滿(man)(man)電存放(fang)(fang)(fang)的(de),還需要注意的(de)就(jiu)是(shi)選擇(ze)品質較(jiao)好的(de)保(bao)護板,鋰電池最大的(de)禁忌就(jiu)是(shi)過(guo)(guo)沖(chong)過(guo)(guo)放(fang)(fang)(fang),三元(yuan)鋰一次過(guo)(guo)放(fang)(fang)(fang)就(jiu)報廢,過(guo)(guo)沖(chong)必定鼓包(bao)也報廢。
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)作(zuo)為電(dian)(dian)(dian)動車電(dian)(dian)(dian)池(chi)(chi)(chi)(chi),在(zai)設(she)計上(shang)有(you)它的(de)(de)優勢(shi)。優勢(shi)表現在(zai)它所提供的(de)(de)開路電(dian)(dian)(dian)源比較大(相比鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi))來說。一個12V的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi),只需要做(zuo)成一個電(dian)(dian)(dian)池(chi)(chi)(chi)(chi),而鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在(zai)作(zuo)為動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)時可能需要串(chuan)聯很多形(xing)成電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)組才可以。對于(yu)動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)設(she)計來說,鉛酸蓄電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)可以比較容易的(de)(de)做(zuo)到,而鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)則需要在(zai)設(she)計,后(hou)期(qi)充電(dian)(dian)(dian),使(shi)用維護中(zhong)遇到很多問題(ti)。從制造成本上(shang)面來講,目前(qian)的(de)(de)動力(li)型電(dian)(dian)(dian)池(chi)(chi)(chi)(chi),前(qian)者要抵,后(hou)者要高(gao)。但鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)未來的(de)(de)發(fa)展趨勢(shi)。
