在現今社會下科技進步飛速，能源與經濟是各國發展基礎的重要來源，從傳統能源近一步向低碳經濟轉型，成為至關重要的部分，尤其以再生能源中常見的風能與太陽能為基礎，使用顯著增加。但由於再生能源會受限於緯度、光照時長、氣候因素是否良好等因素，因此無法穩定發電。於幾年來，配電網中。其改善了運營效率，降低升級配電網之支出成本[1]。在本研究導入電池儲能系統則能改善電力品質等問題，由於電池在運行過程中會產生餘熱，因此電池的溫度會升高。若沒有適當的散熱，電池容易過熱，導致損壞或縮短壽命。故系統會採用強制對流[2]，需要進行電腦模擬計算不同散熱方式對於內部元件溫度的影響。將透過Comsol的電化學分析與電池模擬及熱傳模組，用計算流體力學(CFD)的方式來進行數值模擬。結果將提供內部的速度場、溫度場以及對流熱傳係數作為檢視不同散熱方法好壞的參考。

In today’s society with rapid technological progress, energy and economy are an important source of the development foundation of various countries. The transition from traditional energy to a low-carbon economy has become a crucial part, especially based on wind energy and solar energy, which are common in renewable energy, the usage increased significantly. However, because renewable energy is limited by factors such as latitude, duration of illumination, and whether the climate is good, it cannot generate stable electricity. In the distribution network for several years. It improves operational efficiency and reduces the expenditure cost of upgrading the distribution network. The introduction of the battery energy storage system in this study can improve the power quality and other issues. Since the battery will generate waste heat during operation, the temperature of the battery will increase. Without proper heat dissipation, batteries are prone to overheating, resulting in damage or shortened life. Therefore, forced convection is used in the system, and computer simulation is required to calculate the effect of different heat dissipation methods on the temperature of internal components. The numerical simulation will be carried out by means of computational fluid dynamics (CFD) through Comsol’s electrochemical analysis and battery simulation and heat transfer modules. The results will provide the internal velocity field, temperature field and convective heat transfer coefficient as a reference to check the quality of different heat dissipation methods.
