鋰離(li)子電(dian)池(chi)在生產時，都要進(jin)行高(gao)低溫(wen)(wen)(wen)(wen)試驗(yan)。由于(yu)鋰離(li)子高(gao)溫(wen)(wen)(wen)(wen)有(you)、起火等風險，所以對鋰離(li)子進(jin)行溫(wen)(wen)(wen)(wen)度試驗(yan)的(de)高(gao)低溫(wen)(wen)(wen)(wen)試驗(yan)箱需要有(you)防爆(bao)功能(neng)。近來(lai)出現的(de)可(ke)以快(kuai)速換電(dian)的(de)車型中(zhong)(zhong)，電(dian)池(chi)也有(you)采用液(ye)態溫(wen)(wen)(wen)(wen)控的(de)，與不(bu)換電(dian)的(de)車型相(xiang)比，多了可(ke)快(kuai)速拆接(jie)的(de)管(guan)路接(jie)口。冷卻液(ye)有(you)良(liang)好(hao)的(de)使(shi)用性能(neng)：具有(you)良(liang)好(hao)的(de)流(liu)動(dong)性，能(neng)在溫(wen)(wen)(wen)(wen)控系統中(zhong)(zhong)很好(hao)地流(liu)動(dong)散(san)熱。良(liang)好(hao)的(de)使(shi)用安(an)全性能(neng)：不(bu)導電(dian)，電(dian)絕緣性好(hao)，不(bu)燃不(bu)爆(bao)無燃點閃點，使(shi)用安(an)全。適用范圍廣(guang)：能(neng)廣(guang)泛使(shi)用于(yu)各(ge)種溫(wen)(wen)(wen)(wen)控散(san)熱場(chang)合。

液(ye)(ye)冷(leng)(leng)(leng)系統(tong)(tong)(tong)形式較(jiao)為靈活: 可將(jiang)電(dian)池(chi)(chi)單體或(huo)模(mo)塊沉浸在(zai)液(ye)(ye)體中，也(ye)(ye)可在(zai)電(dian)池(chi)(chi)模(mo)塊間(jian)設置冷(leng)(leng)(leng)卻(que)(que)通(tong)道，或(huo)在(zai)電(dian)池(chi)(chi)底部(bu)(bu)采(cai)用冷(leng)(leng)(leng)卻(que)(que)板。電(dian)池(chi)(chi)與液(ye)(ye)體直接接觸時(shi)(shi)，液(ye)(ye)體必須保證(zheng)絕緣( 如礦物油(you)) ，避(bi)免短路(lu)。同(tong)時(shi)(shi)，對液(ye)(ye)冷(leng)(leng)(leng)系統(tong)(tong)(tong)的(de)(de)氣密性要求也(ye)(ye)較(jiao)高。汽車冷(leng)(leng)(leng)卻(que)(que)液(ye)(ye)具有保護發動機(ji)冷(leng)(leng)(leng)卻(que)(que)系統(tong)(tong)(tong)免遭銹(xiu)蝕和腐蝕，能(neng)有效抑制水垢形成，同(tong)時(shi)(shi)防止溫(wen)度(du)(du)過(guo)低凍(dong)壞(huai)發動機(ji)零部(bu)(bu)件。能(neng)源汽車電(dian)機(ji)需(xu)要冷(leng)(leng)(leng)卻(que)(que)液(ye)(ye)，電(dian)池(chi)(chi)充放電(dian)產(chan)生熱(re)量，需(xu)要冷(leng)(leng)(leng)卻(que)(que)，溫(wen)度(du)(du)低的(de)(de)時(shi)(shi)候(hou)需(xu)要給(gei)電(dian)池(chi)(chi)加(jia)熱(re)，保證(zheng)電(dian)池(chi)(chi)性能(neng)。因為環境(jing)溫(wen)度(du)(du)過(guo)高時(shi)(shi)，動力(li)電(dian)池(chi)(chi)檢(jian)測到電(dian)池(chi)(chi)溫(wen)度(du)(du)超(chao)過(guo)時(shi)(shi)，為了確保動力(li)電(dian)池(chi)(chi)的(de)(de)安(an)全性，車輛(liang)會自動啟動散熱(re)風(feng)扇和電(dian)動水泵(beng)，為動力(li)電(dian)池(chi)(chi)進行散熱(re)。當(dang)我們打開(kai)前(qian)機(ji)艙時(shi)(shi)會發現，有個裝紅(hong)色液(ye)(ye)體的(de)(de)膨脹水壺，這(zhe)里面(mian)就是供電(dian)控、電(dian)驅系統(tong)(tong)(tong)和動力(li)電(dian)池(chi)(chi)冷(leng)(leng)(leng)卻(que)(que)用的(de)(de)冷(leng)(leng)(leng)卻(que)(que)液(ye)(ye)。

冬天(tian)，液(ye)冷(leng)水會(hui)被系統(tong)(tong)加溫(wen)來保護(hu)電(dian)(dian)池(chi)(chi)不(bu)受低溫(wen)影響，不(bu)僅延長(chang)了續航里程，重(zhong)要(yao)的(de)是(shi)保護(hu)了電(dian)(dian)池(chi)(chi)的(de)壽命(ming)。鋰(li)電(dian)(dian)池(chi)(chi)作為電(dian)(dian)動汽車的(de)動力(li)源，電(dian)(dian)池(chi)(chi)內部常因(yin)散(san)熱(re)(re)不(bu)及時導致溫(wen)度(du)過高，從而使(shi)電(dian)(dian)池(chi)(chi)的(de)性(xing)能(neng)下降(jiang)和壽命(ming)縮短，所以電(dian)(dian)池(chi)(chi)均配置散(san)熱(re)(re)系統(tong)(tong)。相(xiang)較于一般車型采用(yong)的(de)傳統(tong)(tong)風(feng)冷(leng)散(san)熱(re)(re)系統(tong)(tong)，動力(li)電(dian)(dian)池(chi)(chi)液(ye)冷(leng)技術優勢更加明顯，散(san)熱(re)(re)效率更高，散(san)熱(re)(re)均衡性(xing)也會(hui)更好(hao)。冷(leng)卻液(ye)換(huan)熱(re)(re)系數高、熱(re)(re)容量大、冷(leng)卻速度(du)快，鋰(li)電(dian)(dian)池(chi)(chi)防(fang)爆恒溫(wen)液(ye)生產價格，對(dui)降(jiang)低高溫(wen)度(du)、提升電(dian)(dian)池(chi)(chi)組溫(wen)度(du)場一致性(xing)的(de)，同時，熱(re)(re)管理系統(tong)(tong)的(de)體(ti)積(ji)也相(xiang)對(dui)較小，是(shi)新能(neng)源電(dian)(dian)池(chi)(chi)散(san)熱(re)(re)的(de)理想冷(leng)卻液(ye)。
