瑞士最新研究：電動汽車快速充電僅需15分鐘

據歐洲(zhou)媒體inautonews報道，瑞(rui)士洛桑聯邦理工學(xue)院(EFPL)研(yan)究(jiu)員證明，在4.5兆瓦的(de)充電(dian)(dian)站完成電(dian)(dian)動車充電(dian)(dian)僅需15分鐘(zhong)，幾乎同加(jia)滿汽車油箱(xiang)一(yi)樣快(kuai)。

對于(yu)(yu)電(dian)(dian)(dian)動汽車(che)來說(shuo)，當(dang)電(dian)(dian)(dian)池的(de)(de)(de)續航(hang)能力提升，充電(dian)(dian)(dian)時間也(ye)會延長。這(zhe)也(ye)是(shi)許多(duo)消費者不(bu)會選(xuan)擇電(dian)(dian)(dian)動車(che)的(de)(de)(de)唯一(yi)原因。瑞士洛桑聯(lian)邦理(li)工學院的(de)(de)(de)研究員們卻表示，電(dian)(dian)(dian)動車(che)充電(dian)(dian)(dian)僅僅需要15分鐘，而(er)使(shi)充電(dian)(dian)(dian)速度(du)加快的(de)(de)(de)唯一(yi)方法就是(shi)提升充電(dian)(dian)(dian)功(gong)率(lv)。快速充電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)功(gong)率(lv)要求為4.5兆瓦，相當(dang)于(yu)(yu)4500臺洗衣機(ji)，但是(shi)這(zhe)樣(yang)大的(de)(de)(de)功(gong)率(lv)足(zu)以使(shi)電(dian)(dian)(dian)網崩(beng)潰。

EFPL的(de)科學家表示，他們已經(jing)找到解決這(zhe)一問(wen)題的(de)方(fang)(fang)法(fa)，不(bu)必(bi)從電(dian)(dian)(dian)網(wang)中(zhong)獲(huo)得全部電(dian)(dian)(dian)能。這(zhe)種(zhong)方(fang)(fang)法(fa)就(jiu)是利用(yong)緩(huan)(huan)沖存(cun)儲(chu)系統，在釋放4.5兆瓦電(dian)(dian)(dian)功率前斷開與電(dian)(dian)(dian)網(wang)的(de)連(lian)接(jie)。EPFL工業電(dian)(dian)(dian)子實驗室研究(jiu)員Alfred Rufer 說：“我們發明了一種(zhong)中(zhong)間(jian)存(cun)儲(chu)系統，利用(yong)緩(huan)(huan)沖存(cun)儲(chu)器(qi)，充(chong)電(dian)(dian)(dian)站可(ke)以不(bu)用(yong)連(lian)接(jie)電(dian)(dian)(dian)網(wang)，給(gei)汽車充(chong)電(dian)(dian)(dian)。” 該技術可(ke)以利用(yong)民用(yong)低壓(ya)電(dian)(dian)(dian)網(wang)或地區性中(zhong)壓(ya)電(dian)(dian)(dian)網(wang)完(wan)成(cheng)，這(zhe)樣可(ke)以顯著減(jian)少投(tou)資。

這種中(zhong)(zhong)間(jian)存(cun)儲系統利(li)用集裝箱大小(xiao)的(de)鋰電(dian)池(chi)(chi)，在(zai)(zai)(zai)低(di)電(dian)能(neng)電(dian)網(wang)中(zhong)(zhong)持續(xu)充(chong)電(dian)。當車輛需要快速充(chong)電(dian)時，緩(huan)沖(chong)電(dian)池(chi)(chi)將存(cun)儲的(de)電(dian)能(neng)傳(chuan)輸給汽(qi)車，因此不(bu)用連接電(dian)網(wang)。為(wei)了(le)提(ti)升這一系統的(de)功能(neng)，研究員和科學家們共同建造了(le)一個演示器。該演示器配有中(zhong)(zhong)間(jian)存(cun)儲電(dian)池(chi)(chi)，從低(di)壓(ya)電(dian)網(wang)中(zhong)(zhong)獲得電(dian)能(neng)，并且在(zai)(zai)(zai)15分鐘內完成標(biao)準電(dian)動車電(dian)池(chi)(chi)充(chong)電(dian)，電(dian)能(neng)達20至30千瓦時。負責協調這一項目(mu)的(de)能(neng)源中(zhong)(zhong)心副主管(guan)Massimiliano Capezzali表示，“我們的(de)目(mu)標(biao)本來是充(chong)電(dian)時間(jian)少于(yu)半(ban)小(xiao)時，但現在(zai)(zai)(zai)看來還有提(ti)升空(kong)間(jian)。
