  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)池快(kuai)充的技術難點：能(neng)(neng)做到20分鐘充滿(man)電(dian)(dian)(dian)，電(dian)(dian)(dian)動汽車(che)的市場競爭力將會明(ming)顯提升。其難點是： a)要有能(neng)(neng)接受(shou)(shou)快(kuai)充的電(dian)(dian)(dian)池。前磷酸(suan)(suan)鐵鋰(li)鋰(li)離子電(dian)(dian)(dian)池來說是可(ke)(ke)能(neng)(neng)的3CA的充電(dian)(dian)(dian)倍(bei)率進行(xing)充電(dian)(dian)(dian)，鈦酸(suan)(suan)鋰(li)電(dian)(dian)(dian)池可(ke)(ke)以(yi)接受(shou)(shou)更(geng)高的10CA的充電(dian)(dian)(dian)倍(bei)率進行(xing)充電(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(nan)(nan)題(ti)之一(yi)：按最佳(jia)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)要求對電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間，至少要3個小時(shi)。因此，電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)方式不(bu)能像燃油汽(qi)(qi)車在(zai)加(jia)油站加(jia)油那樣(yang)，在(zai)像加(jia)油站那樣(yang)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站進行(xing)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。 2)難(nan)(nan)題(ti)之二：電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)(qi)車的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統是各自獨立(li)的(de)。它不(bu)可(ke)能在(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站里并聯充(chong)(chong)電(dian)(dian)(dian)(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

  對電(dian)(dian)池充電(dian)(dian)必須配備(bei)充電(dian)(dian)設備(bei)——充電(dian)(dian)器(qi)。充電(dian)(dian)器(qi)就(jiu)是把交(jiao)流(liu)(liu)電(dian)(dian)網電(dian)(dian)源經過整流(liu)(liu)濾波(bo)后，并經一(yi)系列(lie)調控后，輸出DC電(dian)(dian)源，供給動(dong)力(li)電(dian)(dian)池組進行充電(dian)(dian)，即電(dian)(dian)池組接(jie)受的直流(liu)(liu)電(dian)(dian)。充電(dian)(dian)器(qi)分為(wei)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)(chi)，目前使用(yong)的(de)電(dian)池(chi)(chi)都是二次電(dian)池(chi)(chi)，即(ji)可充(chong)(chong)電(dian)池(chi)(chi)。充(chong)(chong)電(dian)電(dian)池(chi)(chi)的(de)壽命指標是充(chong)(chong)電(dian)次數。通(tong)俗理(li)(li)解(jie)，充(chong)(chong)電(dian)電(dian)池(chi)(chi)隨時(shi)間延長，它會衰減(jian)的(de)。如何(he)防止電(dian)池(chi)(chi)衰減(jian)過快，同時(shi)又要(yao)滿足大(da)眾對充(chong)(chong)電(dian)便捷性的(de)要(yao)求，是大(da)家比(bi)較關心的(de)。下面對電(dian)動汽車充(chong)(chong)電(dian)機理(li)(li)探討(tao)及不...
