2019-3-4 車用動力電池熱安全研究取得階段性進展
動(dong)(dong)力(li)電(dian)(dian)池(chi)熱(re)安全(quan)問題(ti)是影(ying)響電(dian)(dian)動(dong)(dong)汽(qi)(qi)車(che)行駛安全(quan)的(de)關鍵。在國家重點(dian)研發計劃“新能源汽(qi)(qi)車(che)”專項(xiang)2016年度立項(xiang)項(xiang)目“高比(bi)能量動(dong)(dong)力(li)鋰離子電(dian)(dian)池(chi)開發與產業(ye)化技術攻關”的(de)實施中，研發團隊針對高比(bi)能量鋰離子動(dong)(dong)力(li)電(dian)(dian)池(chi)熱(re)安全(quan)機理和(he)安全(quan)設計開展了深(shen)入研究，目前取(qu)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(kuai)充(chong)(chong)(chong)(chong)的(de)(de)(de)(de)技(ji)術難點：能(neng)做到20分鐘(zhong)充(chong)(chong)(chong)(chong)滿電(dian)，電(dian)動汽車的(de)(de)(de)(de)市場競爭力將會明顯提(ti)升。其難點是(shi)： a)要有(you)能(neng)接(jie)(jie)受快(kuai)充(chong)(chong)(chong)(chong)的(de)(de)(de)(de)電(dian)池。前(qian)磷酸(suan)鐵鋰鋰離子(zi)電(dian)池來(lai)說是(shi)可(ke)(ke)能(neng)的(de)(de)(de)(de)3CA的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)倍率進行(xing)(xing)充(chong)(chong)(chong)(chong)電(dian)，鈦(tai)酸(suan)鋰電(dian)池可(ke)(ke)以接(jie)(jie)受更高的(de)(de)(de)(de)10CA的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)倍率進行(xing)(xing)充(chong)(chong)(chong)(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)難題之一(yi)：按最(zui)佳充(chong)(chong)(chong)電(dian)(dian)(dian)要求對電(dian)(dian)(dian)動汽車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)時間，至少要3個小時。因此，電(dian)(dian)(dian)動汽車(che)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)方式不能(neng)(neng)像燃油(you)(you)汽車(che)在(zai)(zai)加油(you)(you)站加油(you)(you)那樣，在(zai)(zai)像加油(you)(you)站那樣的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)站進行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)。 2)難題之二(er)：電(dian)(dian)(dian)動汽車(che)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)系統是各自獨立的(de)。它不可能(neng)(neng)在(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)站里(li)并(bing)聯充(chong)(chong)(chong)電(dian)(dian)(dian)。也(ye)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(chi)充(chong)(chong)電(dian)(dian)必(bi)須配備充(chong)(chong)電(dian)(dian)設備——充(chong)(chong)電(dian)(dian)器(qi)(qi)。充(chong)(chong)電(dian)(dian)器(qi)(qi)就是把(ba)交流電(dian)(dian)網電(dian)(dian)源(yuan)經過整流濾波后，并經一系列(lie)調控(kong)后，輸出DC電(dian)(dian)源(yuan)，供給(gei)動(dong)力電(dian)(dian)池(chi)組進行(xing)充(chong)(chong)電(dian)(dian)，即電(dian)(dian)池(chi)組接受的直流電(dian)(dian)。充(chong)(chong)電(dian)(dian)器(qi)(qi)分為三類(lei)：...
2019-2-28 如何提升充電便捷性
電(dian)(dian)動汽車動力(li)源(yuan)于(yu)電(dian)(dian)池(chi)，目(mu)前使(shi)用的(de)電(dian)(dian)池(chi)都是(shi)二次電(dian)(dian)池(chi)，即可充(chong)(chong)電(dian)(dian)池(chi)。充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)的(de)壽命(ming)指標(biao)是(shi)充(chong)(chong)電(dian)(dian)次數。通俗理解，充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)隨時(shi)間延長，它會衰(shuai)減的(de)。如何防止電(dian)(dian)池(chi)衰(shuai)減過快，同時(shi)又要(yao)滿(man)足大眾對充(chong)(chong)電(dian)(dian)便(bian)捷性的(de)要(yao)求，是(shi)大家比較關心(xin)的(de)。下面對電(dian)(dian)動汽車充(chong)(chong)電(dian)(dian)機理探討及不...
