  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)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)快充(chong)(chong)的技術(shu)難點：能(neng)做到(dao)20分鐘充(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽車的市場競(jing)爭力將會明(ming)顯提升。其(qi)難點是(shi)： a)要有能(neng)接(jie)受快充(chong)(chong)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。前磷(lin)酸鐵鋰(li)(li)鋰(li)(li)離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)來(lai)說是(shi)可能(neng)的3CA的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)倍率進(jin)行(xing)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，鈦(tai)酸鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)可以接(jie)受更高的10CA的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)倍率進(jin)行(xing)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(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)之一：按最佳(jia)充(chong)(chong)電(dian)(dian)(dian)要(yao)求對電(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)(che)充(chong)(chong)電(dian)(dian)(dian)的(de)充(chong)(chong)電(dian)(dian)(dian)時間，至少要(yao)3個小(xiao)時。因此，電(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)(che)的(de)充(chong)(chong)電(dian)(dian)(dian)方(fang)式(shi)不(bu)能(neng)像(xiang)燃油汽(qi)(qi)車(che)(che)在(zai)加(jia)油站加(jia)油那樣(yang)，在(zai)像(xiang)加(jia)油站那樣(yang)的(de)充(chong)(chong)電(dian)(dian)(dian)站進行充(chong)(chong)電(dian)(dian)(dian)。 2)難題(ti)之二：電(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)(che)的(de)充(chong)(chong)電(dian)(dian)(dian)系統(tong)是各自(zi)獨立(li)的(de)。它(ta)不(bu)可(ke)能(neng)在(zai)充(chong)(chong)電(dian)(dian)(dian)站里并聯(lian)充(chong)(chong)電(dian)(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(dui)電(dian)池(chi)(chi)充(chong)電(dian)必須(xu)配備充(chong)電(dian)設(she)備——充(chong)電(dian)器。充(chong)電(dian)器就是把交流(liu)(liu)(liu)電(dian)網(wang)電(dian)源經過整流(liu)(liu)(liu)濾(lv)波后，并經一系列調(diao)控后，輸(shu)出(chu)DC電(dian)源，供給動(dong)力電(dian)池(chi)(chi)組進行充(chong)電(dian)，即電(dian)池(chi)(chi)組接受的直流(liu)(liu)(liu)電(dian)。充(chong)電(dian)器分為三類：...

  2019-2-28 如何提升充電便捷性

  電(dian)動汽車動力源于電(dian)池(chi)，目前(qian)使用的電(dian)池(chi)都(dou)是(shi)二次電(dian)池(chi)，即可充電(dian)池(chi)。充電(dian)電(dian)池(chi)的壽命指(zhi)標是(shi)充電(dian)次數(shu)。通俗(su)理解(jie)，充電(dian)電(dian)池(chi)隨時間延長(chang)，它會衰減(jian)的。如(ru)何防(fang)止(zhi)電(dian)池(chi)衰減(jian)過快(kuai)，同時又要滿(man)足大(da)眾對充電(dian)便捷性的要求，是(shi)大(da)家比較(jiao)關(guan)心的。下(xia)面對電(dian)動汽車充電(dian)機理探討及不...
