  2019-3-1 電池快充(快換)是市場對電動汽車的必然要求

  1)電(dian)池(chi)(chi)快充(chong)的(de)技術難點：能(neng)做到20分鐘充(chong)滿電(dian)，電(dian)動汽車的(de)市場(chang)競爭力將會明顯提(ti)升。其難點是(shi)： a)要有能(neng)接(jie)受快充(chong)的(de)電(dian)池(chi)(chi)。前磷酸鐵鋰鋰離子電(dian)池(chi)(chi)來說是(shi)可能(neng)的(de)3CA的(de)充(chong)電(dian)倍率(lv)進(jin)行(xing)充(chong)電(dian)，鈦酸鋰電(dian)池(chi)(chi)可以接(jie)受更高的(de)10CA的(de)充(chong)電(dian)倍率(lv)進(jin)行(xing)充(chong)電(dian)。 b)2...

  2019-3-1 充電時間長是電動汽車推廣應用的一個難題

  1)難題之(zhi)一：按最(zui)佳充(chong)電(dian)(dian)要(yao)求對電(dian)(dian)動(dong)汽車充(chong)電(dian)(dian)的(de)充(chong)電(dian)(dian)時(shi)間，至少要(yao)3個小(xiao)時(shi)。因此，電(dian)(dian)動(dong)汽車的(de)充(chong)電(dian)(dian)方式(shi)不能(neng)像(xiang)(xiang)燃油(you)汽車在加油(you)站加油(you)那樣，在像(xiang)(xiang)加油(you)站那樣的(de)充(chong)電(dian)(dian)站進行充(chong)電(dian)(dian)。 2)難題之(zhi)二：電(dian)(dian)動(dong)汽車的(de)充(chong)電(dian)(dian)系統(tong)是各(ge)自獨立的(de)。它(ta)不可(ke)能(neng)在充(chong)電(dian)(dian)站里并聯(lian)充(chong)電(dian)(dian)。也就...

  2019-2-28 對電池充電實際上“電”能轉換成“化學”能過程

  對電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)必(bi)須配備充(chong)電(dian)(dian)(dian)設備——充(chong)電(dian)(dian)(dian)器(qi)。充(chong)電(dian)(dian)(dian)器(qi)就是把交流電(dian)(dian)(dian)網電(dian)(dian)(dian)源(yuan)(yuan)經過(guo)整流濾(lv)波(bo)后(hou)，并經一系列調控后(hou)，輸(shu)出DC電(dian)(dian)(dian)源(yuan)(yuan)，供給動力電(dian)(dian)(dian)池組進行充(chong)電(dian)(dian)(dian)，即電(dian)(dian)(dian)池組接受的直流電(dian)(dian)(dian)。充(chong)電(dian)(dian)(dian)器(qi)分為三類：...

  2019-2-28 如何提升充電便捷性

  電(dian)(dian)(dian)動(dong)(dong)汽(qi)車(che)動(dong)(dong)力源于電(dian)(dian)(dian)池(chi)(chi)(chi)，目前使用的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)都是二(er)次電(dian)(dian)(dian)池(chi)(chi)(chi)，即可充電(dian)(dian)(dian)池(chi)(chi)(chi)。充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)壽命指標(biao)是充電(dian)(dian)(dian)次數。通俗理(li)解(jie)，充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)隨時間延長，它會衰減的(de)(de)。如何防止電(dian)(dian)(dian)池(chi)(chi)(chi)衰減過快，同時又(you)要(yao)滿足大眾對充電(dian)(dian)(dian)便捷性的(de)(de)要(yao)求，是大家(jia)比較關心的(de)(de)。下(xia)面對電(dian)(dian)(dian)動(dong)(dong)汽(qi)車(che)充電(dian)(dian)(dian)機理(li)探討及(ji)不...
