  2019-3-4 車用動力電池熱安全研究取得階段性進展

  動(dong)力電池(chi)熱安全(quan)(quan)問(wen)題是影(ying)響電動(dong)汽(qi)車(che)行(xing)駛安全(quan)(quan)的關(guan)鍵。在國家重(zhong)點研發(fa)(fa)計劃(hua)“新能源汽(qi)車(che)”專(zhuan)項2016年度立項項目(mu)“高比能量動(dong)力鋰離子電池(chi)開發(fa)(fa)與產業化技術(shu)攻關(guan)”的實(shi)施中，研發(fa)(fa)團隊(dui)針對(dui)高比能量鋰離子動(dong)力電池(chi)熱安全(quan)(quan)機理(li)和安全(quan)(quan)設計開展了深入研究(jiu)，目(mu)前取得了...

  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)池快充的(de)技(ji)術難點：能做到20分(fen)鐘充滿電(dian)，電(dian)動汽(qi)車的(de)市場競爭力將會明(ming)顯提(ti)升。其(qi)難點是(shi)： a)要有能接(jie)受(shou)快充的(de)電(dian)池。前磷(lin)酸(suan)鐵鋰鋰離子電(dian)池來說是(shi)可能的(de)3CA的(de)充電(dian)倍率進行充電(dian)，鈦酸(suan)鋰電(dian)池可以接(jie)受(shou)更高的(de)10CA的(de)充電(dian)倍率進行充電(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(ti)之(zhi)一：按最佳充(chong)電(dian)(dian)(dian)(dian)要(yao)求對電(dian)(dian)(dian)(dian)動(dong)汽(qi)車(che)充(chong)電(dian)(dian)(dian)(dian)的充(chong)電(dian)(dian)(dian)(dian)時間，至(zhi)少要(yao)3個小時。因此，電(dian)(dian)(dian)(dian)動(dong)汽(qi)車(che)的充(chong)電(dian)(dian)(dian)(dian)方式不能(neng)像(xiang)(xiang)燃油汽(qi)車(che)在加(jia)油站加(jia)油那樣(yang)，在像(xiang)(xiang)加(jia)油站那樣(yang)的充(chong)電(dian)(dian)(dian)(dian)站進行(xing)充(chong)電(dian)(dian)(dian)(dian)。 2)難題(ti)之(zhi)二：電(dian)(dian)(dian)(dian)動(dong)汽(qi)車(che)的充(chong)電(dian)(dian)(dian)(dian)系統是各自獨立的。它不可能(neng)在充(chong)電(dian)(dian)(dian)(dian)站里并聯充(chong)電(dian)(dian)(dian)(dian)。也(ye)就(jiu)...

  2019-2-28 對電池充電實際上“電”能轉換成“化學”能過程

  對電(dian)池充(chong)電(dian)必須配備充(chong)電(dian)設備——充(chong)電(dian)器(qi)。充(chong)電(dian)器(qi)就是把交流(liu)(liu)電(dian)網電(dian)源經(jing)過整流(liu)(liu)濾(lv)波后(hou)，并經(jing)一系(xi)列調控后(hou)，輸(shu)出DC電(dian)源，供給動力電(dian)池組(zu)(zu)進行充(chong)電(dian)，即電(dian)池組(zu)(zu)接受的直流(liu)(liu)電(dian)。充(chong)電(dian)器(qi)分為(wei)三類：...

  2019-2-28 如何提升充電便捷性

  電(dian)(dian)(dian)動汽車(che)動力源于電(dian)(dian)(dian)池(chi)，目(mu)前(qian)使用的電(dian)(dian)(dian)池(chi)都是(shi)二次電(dian)(dian)(dian)池(chi)，即可充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)池(chi)。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)的壽命指標(biao)是(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)次數。通俗理(li)解，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)隨時(shi)間延(yan)長，它會衰減的。如何防止(zhi)電(dian)(dian)(dian)池(chi)衰減過快，同時(shi)又(you)要滿足大眾對充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)便捷性的要求，是(shi)大家比較(jiao)關心的。下面對電(dian)(dian)(dian)動汽車(che)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機理(li)探討及(ji)不...
