電池熱特性參數測試具備符合(he)GB/T 36276-2023《電(dian)(dian)(dian)力儲能(neng)(neng)用(yong)鋰離(li)子電(dian)(dian)(dian)池(chi)(chi)(chi)》“絕熱(re)溫(wen)升特(te)性”實驗標準的(de)專用(yong)測試(shi)(shi)模式，是研究長邊100mm~900mm之(zhi)間大(da)型(xing)電(dian)(dian)(dian)池(chi)(chi)(chi)單體及(ji)其小型(xing)模組的(de)絕熱(re)量熱(re)儀，可(ke)實現電(dian)(dian)(dian)池(chi)(chi)(chi)熱(re)失(shi)(shi)控(kong)測試(shi)(shi)、電(dian)(dian)(dian)池(chi)(chi)(chi)產(chan)(chan)氣(qi)測試(shi)(shi)、電(dian)(dian)(dian)池(chi)(chi)(chi)充放(fang)電(dian)(dian)(dian)產(chan)(chan)熱(re)測試(shi)(shi)、電(dian)(dian)(dian)池(chi)(chi)(chi)比(bi)熱(re)容測試(shi)(shi)，精準獲(huo)取鋰電(dian)(dian)(dian)池(chi)(chi)(chi)低溫(wen)狀態下的(de)充放(fang)電(dian)(dian)(dian)產(chan)(chan)熱(re)和比(bi)熱(re)容、熱(re)失(shi)(shi)控(kong)起始溫(wen)度(du)、最大(da)熱(re)失(shi)(shi)控(kong)速率、絕熱(re)溫(wen)升特(te)性、電(dian)(dian)(dian)池(chi)(chi)(chi)產(chan)(chan)氣(qi)量和產(chan)(chan)氣(qi)速率等參數。儀器可(ke)為鋰電(dian)(dian)(dian)池(chi)(chi)(chi)及(ji)電(dian)(dian)(dian)池(chi)(chi)(chi)模組安全性能(neng)(neng)評估(gu)提供數據支(zhi)持；為動力電(dian)(dian)(dian)池(chi)(chi)(chi)低溫(wen)熱(re)管理系統提供評價依(yi)據。該(gai)儀器具備絕熱(re)熱(re)失(shi)(shi)控(kong)、氣(qi)體收集及(ji)壓力測試(shi)(shi)、熱(re)/電(dian)(dian)(dian)/機械(xie)濫用(yong)、比(bi)熱(re)容測試(shi)(shi)、充放(fang)電(dian)(dian)(dian)產(chan)(chan)熱(re)測試(shi)(shi)、多點溫(wen)度(du)測量、視頻監控(kong)、加(jia)熱(re)絲輔助加(jia)熱(re)等功(gong)能(neng)(neng)。 熱(re)特性(xing)參數(shu)的(de)(de)測試數(shu)據(ju)是電(dian)池(chi)設計和優化的(de)(de)重要依據(ju)。通過(guo)分析(xi)這些參數(shu)，工(gong)(gong)程(cheng)師可(ke)以設計出更合(he)理的(de)(de)電(dian)池(chi)包(bao)結構，選擇合(he)適的(de)(de)散熱(re)材料(liao)和熱(re)管理系(xi)統，以確保(bao)電(dian)池(chi)在不同(tong)工(gong)(gong)況下(xia)都能保(bao)持(chi)在工(gong)(gong)作溫(wen)度范圍內，避免過(guo)熱(re)導(dao)致的(de)(de)性(xing)能衰(shuai)減(jian)和安(an)全風險。
在電(dian)動汽車、儲能(neng)系(xi)(xi)統等應用中，電(dian)池的(de)(de)熱管(guan)(guan)理是決定系(xi)(xi)統整(zheng)體性(xing)能(neng)和可靠性(xing)的(de)(de)關鍵因素(su)。通過對(dui)電(dian)池熱特性(xing)的(de)(de)深(shen)入(ru)研究，可以開發出(chu)更(geng)(geng)高效(xiao)(xiao)、更(geng)(geng)安全的(de)(de)電(dian)池管(guan)(guan)理系(xi)(xi)統(BMS)，實現電(dian)池能(neng)量(liang)的(de)(de)利用，延長(chang)電(dian)池壽(shou)命，提高系(xi)(xi)統的(de)(de)整(zheng)體效(xiao)(xiao)率。
電池(chi)(chi)熱特(te)性(xing)參數的(de)(de)(de)測試(shi)不(bu)僅是電池(chi)(chi)研發(fa)(fa)過程中的(de)(de)(de)必要(yao)步驟，也是電池(chi)(chi)產品安全認證和(he)質(zhi)量控制的(de)(de)(de)重(zhong)要(yao)組(zu)成部分。隨(sui)著電池(chi)(chi)技(ji)術的(de)(de)(de)不(bu)斷進步和(he)應用場景的(de)(de)(de)日益(yi)多(duo)樣化，對電池(chi)(chi)熱特(te)性(xing)的(de)(de)(de)深入(ru)理解和(he)精(jing)準測試(shi)變得愈發(fa)(fa)重(zhong)要(yao)。未來，隨(sui)著測試(shi)技(ji)術的(de)(de)(de)創新，我們期待看到更多(duo)高(gao)性(xing)能(neng)、高(gao)安全性(xing)的(de)(de)(de)電池(chi)(chi)產品涌現(xian)，推動新能(neng)源技(ji)術的(de)(de)(de)持續發(fa)(fa)展(zhan)。
