車輛出(chu)廠時(shi)，動(dong)力(li)電(dian)(dian)池(chi)(chi)冷(leng)(leng)卻系(xi)(xi)統(tong)已加(jia)注冷(leng)(leng)卻液(ye)(ye)，在(zai)規(gui)定的保(bao)養期檢(jian)查采(cai)暖系(xi)(xi)統(tong)冷(leng)(leng)卻液(ye)(ye)液(ye)(ye)位。在(zai)規(gui)定的保(bao)養期檢(jian)查動(dong)力(li)電(dian)(dian)池(chi)(chi)冷(leng)(leng)卻液(ye)(ye)液(ye)(ye)位。液(ye)(ye)體(ti)(ti)冷(leng)(leng)卻技術(shu)通過(guo)液(ye)(ye)體(ti)(ti)對流換熱(re)，將電(dian)(dian)池(chi)(chi)產生的熱(re)量(liang)帶走，降低電(dian)(dian)池(chi)(chi)溫(wen)度(du)。液(ye)(ye)體(ti)(ti)介質(zhi)的換熱(re)系(xi)(xi)數高、熱(re)容量(liang)大、冷(leng)(leng)卻速度(du)快，對降低溫(wen)度(du)、提升電(dian)(dian)池(chi)(chi)組溫(wen)度(du)場(chang)一致性(xing)(xing)的，同(tong)時(shi)，熱(re)管理系(xi)(xi)統(tong)的體(ti)(ti)積(ji)也相對較小。鋰(li)電(dian)(dian)池(chi)(chi)作為電(dian)(dian)動(dong)汽車的動(dong)力(li)源，電(dian)(dian)池(chi)(chi)內部常因散(san)熱(re)不及時(shi)導致溫(wen)度(du)過(guo)高，從而使電(dian)(dian)池(chi)(chi)的性(xing)(xing)能下降和壽命縮短(duan)，所以電(dian)(dian)池(chi)(chi)均配置散(san)熱(re)系(xi)(xi)統(tong)。相較于一般車型采(cai)用的傳統(tong)風冷(leng)(leng)散(san)熱(re)系(xi)(xi)統(tong)，動(dong)力(li)電(dian)(dian)池(chi)(chi)液(ye)(ye)冷(leng)(leng)技術(shu)優勢更(geng)加(jia)明顯，散(san)熱(re)效率(lv)更(geng)高，散(san)熱(re)均衡性(xing)(xing)也會(hui)更(geng)好。

液(ye)(ye)冷(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)形式較為靈活: 可(ke)(ke)將電(dian)(dian)(dian)池(chi)(chi)(chi)單體(ti)或(huo)模塊(kuai)(kuai)沉浸在(zai)液(ye)(ye)體(ti)中，也(ye)可(ke)(ke)在(zai)電(dian)(dian)(dian)池(chi)(chi)(chi)模塊(kuai)(kuai)間設(she)置冷(leng)(leng)(leng)(leng)卻通(tong)道，或(huo)在(zai)電(dian)(dian)(dian)池(chi)(chi)(chi)底部采(cai)(cai)用(yong)冷(leng)(leng)(leng)(leng)卻板。電(dian)(dian)(dian)池(chi)(chi)(chi)與(yu)液(ye)(ye)體(ti)直接(jie)接(jie)觸時，鋰電(dian)(dian)(dian)池(chi)(chi)(chi)防(fang)爆(bao)恒溫液(ye)(ye)報價，液(ye)(ye)體(ti)必須(xu)保證(zheng)絕(jue)緣( 如礦物油(you)) ，避免短路。同(tong)時，對(dui)液(ye)(ye)冷(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)的(de)氣密性要求也(ye)較高。新能源汽車驅動系(xi)(xi)統(tong)中一(yi)般采(cai)(cai)用(yong)風冷(leng)(leng)(leng)(leng)、液(ye)(ye)冷(leng)(leng)(leng)(leng)組合的(de)設(she)計來保證(zheng)整個(ge)系(xi)(xi)統(tong)的(de)安全(quan)運(yun)轉，其中液(ye)(ye)冷(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)依(yi)靠(kao)冷(leng)(leng)(leng)(leng)卻水泵帶(dai)動冷(leng)(leng)(leng)(leng)卻液(ye)(ye)在(zai)冷(leng)(leng)(leng)(leng)卻管(guan)道中循環流(liu)動，通(tong)過在(zai)散熱(re)器(qi)的(de)熱(re)交換等過程，冷(leng)(leng)(leng)(leng)卻液(ye)(ye)帶(dai)走電(dian)(dian)(dian)動機與(yu)控制(zhi)器(qi)產(chan)生的(de)熱(re)量。冷(leng)(leng)(leng)(leng)卻液(ye)(ye)換熱(re)系(xi)(xi)數(shu)高、熱(re)容(rong)量大(da)、冷(leng)(leng)(leng)(leng)卻速(su)度快，對(dui)降低(di)高溫度、提升電(dian)(dian)(dian)池(chi)(chi)(chi)組溫度場一(yi)致性的(de)，同(tong)時，熱(re)管(guan)理(li)系(xi)(xi)統(tong)的(de)體(ti)積也(ye)相對(dui)較小(xiao)，是新能源電(dian)(dian)(dian)池(chi)(chi)(chi)散熱(re)的(de)理(li)想冷(leng)(leng)(leng)(leng)卻液(ye)(ye)。

新(xin)能源汽(qi)車(che)驅動系(xi)(xi)(xi)統(tong)(tong)中一般采用風冷、液冷組合的(de)設計來保證整個系(xi)(xi)(xi)統(tong)(tong)的(de)安全運(yun)轉，其中液冷系(xi)(xi)(xi)統(tong)(tong)依靠(kao)冷卻(que)(que)(que)(que)水泵帶(dai)動冷卻(que)(que)(que)(que)液在冷卻(que)(que)(que)(que)管道中循環流動，通過(guo)在散(san)熱(re)器的(de)熱(re)交(jiao)換等過(guo)程，冷卻(que)(que)(que)(que)液帶(dai)走(zou)電(dian)動機(ji)與控制器產生的(de)熱(re)量。冷卻(que)(que)(que)(que)液換熱(re)系(xi)(xi)(xi)數(shu)高、熱(re)容量大、冷卻(que)(que)(que)(que)速(su)度(du)快，對降(jiang)低高溫度(du)、提升電(dian)池組溫度(du)場一致性(xing)的(de)，同時，熱(re)管理系(xi)(xi)(xi)統(tong)(tong)的(de)體積也(ye)相對較(jiao)小，是新(xin)能源電(dian)池散(san)熱(re)的(de)理想冷卻(que)(que)(que)(que)液。電(dian)動汽(qi)車(che)恒溫液通過(guo)提供溫控以(yi)提升動力電(dian)池的(de)使用性(xing)能和(he)(he)使用壽命，從(cong)主動安全和(he)(he)被動安全兩方面解決安全性(xing)問題。
