目前(qian)國內主流廠家絕大多(duo)(duo)數(shu)均采用(yong)液冷(leng)技術，用(yong)溫(wen)控(kong)(kong)液來作(zuo)為散熱流體介(jie)質。可當電(dian)池受到外力作(zuo)用(yong)而(er)(er)被破壞時，溫(wen)控(kong)(kong)液易進入電(dian)池內部，從而(er)(er)會引發電(dian)池短路(lu)、燃燒或(huo)等安全問(wen)題。如何通(tong)過液冷(leng)技術創(chuang)新來改(gai)善(shan)電(dian)池此類的安全問(wen)題顯得至(zhi)關重要。近來出現(xian)的可以快速換電(dian)的車型中，電(dian)池也(ye)有采用(yong)液態溫(wen)控(kong)(kong)的，與不換電(dian)的車型相比，多(duo)(duo)了可快速拆(chai)接的管(guan)路(lu)接口。當前(qian)鋰(li)離(li)子(zi)電(dian)池廣泛(fan)應用(yong)于手機、筆(bi)記(ji)本電(dian)腦、電(dian)動汽車等等，但鋰(li)電(dian)池在(zai)溫(wen)度太(tai)高或(huo)太(tai)低時都容易“”，嚴重時，鋰(li)電(dian)池防爆溫(wen)控(kong)(kong)液，可能還會產生、起火。

液冷(leng)系(xi)統(tong)形式較為靈活: 可將電(dian)池單(dan)體(ti)(ti)或模(mo)塊(kuai)沉浸在液體(ti)(ti)中，也(ye)可在電(dian)池模(mo)塊(kuai)間設置冷(leng)卻(que)通道，或在電(dian)池底部采用冷(leng)卻(que)板。電(dian)池與液體(ti)(ti)直接接觸(chu)時(shi)(shi)，液體(ti)(ti)必須保證絕緣( 如礦物(wu)油) ，避免短路。同時(shi)(shi)，對液冷(leng)系(xi)統(tong)的(de)氣密性(xing)要(yao)求也(ye)較高。冷(leng)卻(que)液換熱(re)系(xi)數高、熱(re)容量(liang)大、冷(leng)卻(que)速(su)度(du)快(kuai)，對降低高溫(wen)度(du)、提升電(dian)池組溫(wen)度(du)場一致性(xing)的(de)，同時(shi)(shi)，熱(re)管(guan)理系(xi)統(tong)的(de)體(ti)(ti)積也(ye)相對較小(xiao)，是(shi)新(xin)能源電(dian)池散熱(re)的(de)理想(xiang)冷(leng)卻(que)液。當(dang)車(che)輛(liang)需要(yao)進(jin)(jin)行(xing)冷(leng)卻(que)時(shi)(shi)，膨脹水壺內的(de)冷(leng)卻(que)液通過(guo)管(guan)道進(jin)(jin)入到(dao)車(che)輛(liang)前部的(de)冷(leng)凝(ning)器，然(ran)后通過(guo)撞(zhuang)風(feng)帶(dai)走散熱(re)器內部冷(leng)卻(que)液溫(wen)度(du)，使溫(wen)度(du)進(jin)(jin)一步降低。

液(ye)(ye)冷(leng)系(xi)(xi)統(tong)形(xing)式較(jiao)為靈活: 可將(jiang)電(dian)(dian)池單體或模塊沉浸在(zai)(zai)液(ye)(ye)體中，也(ye)可在(zai)(zai)電(dian)(dian)池模塊間設置冷(leng)卻(que)(que)(que)通道，或在(zai)(zai)電(dian)(dian)池底部(bu)采用(yong)冷(leng)卻(que)(que)(que)板。電(dian)(dian)池與液(ye)(ye)體直接接觸時(shi)，液(ye)(ye)體必須(xu)保(bao)(bao)證絕緣( 如礦(kuang)物(wu)油(you)) ，避免短(duan)路。同時(shi)，對液(ye)(ye)冷(leng)系(xi)(xi)統(tong)的氣密(mi)性要(yao)(yao)求也(ye)較(jiao)高(gao)。汽車(che)冷(leng)卻(que)(que)(que)液(ye)(ye)具有保(bao)(bao)護發動(dong)(dong)(dong)機(ji)(ji)冷(leng)卻(que)(que)(que)系(xi)(xi)統(tong)免遭(zao)銹蝕和腐蝕，能(neng)有效抑制水垢形(xing)成(cheng)，同時(shi)防止(zhi)溫度過低(di)(di)凍(dong)壞發動(dong)(dong)(dong)機(ji)(ji)零部(bu)件(jian)。能(neng)源汽車(che)電(dian)(dian)機(ji)(ji)需要(yao)(yao)冷(leng)卻(que)(que)(que)液(ye)(ye)，電(dian)(dian)池充放(fang)電(dian)(dian)產(chan)生熱(re)(re)量，需要(yao)(yao)冷(leng)卻(que)(que)(que)，溫度低(di)(di)的時(shi)候需要(yao)(yao)給電(dian)(dian)池加熱(re)(re)，保(bao)(bao)證電(dian)(dian)池性能(neng)。因為環境(jing)溫度過高(gao)時(shi)，動(dong)(dong)(dong)力(li)電(dian)(dian)池檢測到電(dian)(dian)池溫度超過時(shi)，為了確保(bao)(bao)動(dong)(dong)(dong)力(li)電(dian)(dian)池的安全性，車(che)輛會(hui)自動(dong)(dong)(dong)啟(qi)動(dong)(dong)(dong)散熱(re)(re)風扇和電(dian)(dian)動(dong)(dong)(dong)水泵(beng)，為動(dong)(dong)(dong)力(li)電(dian)(dian)池進行散熱(re)(re)。當我們打開前(qian)機(ji)(ji)艙時(shi)會(hui)發現，有個(ge)裝紅色液(ye)(ye)體的膨脹水壺，這里面(mian)就是供電(dian)(dian)控、電(dian)(dian)驅(qu)系(xi)(xi)統(tong)和動(dong)(dong)(dong)力(li)電(dian)(dian)池冷(leng)卻(que)(que)(que)用(yong)的冷(leng)卻(que)(que)(que)液(ye)(ye)。
