因應全球的減碳趨勢，低污染的電動車將成為下個世代的主流交通工具，電動車目前面臨最大的問題便是續航力與充電耗時，而這兩個問題與電池的工作溫度關係密切。本篇論文是以電熱棒來模擬電動車電池包的實際發熱情形，並在電池包間隙中插入自製的脈衝式熱管，觀察在不同間隙的填充物下在不同加熱功率下的溫度分布情形。在25°C、1atm、相同加熱源下，插入自製脈衝式熱管與自製的相變化材料作為電池包間隙填充物下的實驗組，相較於完全無任何添加物的對照組，最高溫從90.6°C下降至58.4°C，其均溫度δ從2.135%～1.320%降至0.121%～0.060%。

React to the carbon reduction, low-pollution electric vehicles have almost become a trend in next generation. However, electric vehicles are faced with some problems like charging time and endurance ability, both problems are in highly connected with working temperature. This research focuses on simulating practical heating condition of battery pack in electric vehicles. Pulsating heat pipes (PHPs) are inserted in the gap of the battery pack and different materials are filled in the gap of the battery pack individually at 25°C and 1atm. At the same heating condition, the test group, which PHPs are inserted in the gap of the battery pack and the self-made Phase Change Material(PCM) is filled in the gap of the battery pack, compare to the
comparison group, which is not inserted any temperature equalizing element and the gap of the battery pack is filled in air, the maximum temperature from 90.6°C to 58.4°C and the temperature equalizing parameter(δ) from 2.135%～1.320% to 0.121%～0.060%.
