本研究將針對商用21700圓柱型鋰離子電池芯進行發熱量量測，利用自行設計治具來建立發熱量量測平台，藉由量測的溫度曲線來計算出單電池芯於1C、1.5C及2C放電時的發熱量。
接著本文將設計由28顆21700所組成的58.8V動力型鋰電池模組並搭配水冷散熱系統作為熱管理，且針對此2P14S之電池模組進行電場與熱流場的模擬分析，以數值方法求解電場和熱流場。
最後將電池模組與水冷散熱系統建立完成，並量測電池模組內特定監測點於各C-rate放電情況下之溫度，以及觀察改變水冷流速後所造成的溫度影響，再將其溫度數據進行比較和討論，改善出最佳的電池熱管理系統。
In this study, a thermal measurement equipment was designed and applied to the commercial 21700 cylindrical lithium-ion battery to conduct thermal measurement. With the recorded temperature profile, the heat generation of single battery cell discharging at 1C, 1.5C and 2C can be calculated. Afterwards, the 58.8V power lithium battery module consisted of 28 21700 battery cell was combined with water cooling system to do the thermal management. In addition, the 2P14S battery module was applied to conduct electric field, flow and thermal field simulation which was analyzed by using the numerical method. As the battery module and water cooling system were established, the temperature of the battery module in each C-rate discharge can be measured. The temperature variation caused by the change of water cooling flow rate was also an important observation. With the comparison and discussion of the temperature record, the previous problem is improved and the best battery thermal management system is established.
