電池熱管理系統(Battery Thermal Management System，BTMS) 是各電池系統中幫助鋰電池在工作時保持在適當的溫度範圍中，以此確保鋰電池的輸出效率、壽命、安全性等各項性能，本研究提出以novel ALVC + Al plate + cold plate來設計BTMS ，因為novel ALVC的結構不同於傳統的VC，有著更多的支撐柱以減少工作流體的回水路徑，使得熱阻更小，且厚度會較傳統VC更薄有望增加抗重力的能力，預期novel ALVC改善電池模組中的單顆電池溫度與溫度差以及模組中各電池的溫度差。透過實驗的方式將電池的熱參數(熱傳導係數、比熱)以及發熱量，後面將前面側出的參數與發熱量輸進Fluent利用模擬的方式求出在cold plate內的入口流量為20 GPH下，Al plate的最佳厚度，得到在電池間加入 10 mm 厚的Al plate能很好的改善電池表面的平均溫度以及表面溫差，再以實驗進行驗證，比對自然對流、cold plate only、ALVC + cold plate與Al-plate + ALVC + cold plate對於模組中單電池的溫度影響，以及模組內各電池間的均溫效果，最後顯示對比自然對流， Al-plate + ALVC + cold plate的平均溫升有著58%的改善，溫差提升了48%的影響，而對電池模組中的溫度有著68.8%的改善。

A Battery Thermal Management System (BTMS) is essential for maintaining lithium batteries within an optimal temperature range during operation, ensuring performance, longevity, and safety. This study proposes a novel BTMS design using ALVC, Al-plate, and cold plate. The novel ALVC features additional support columns to reduce the working fluid's return path, resulting in lower thermal resistance and increased resistance to gravity due to its thinner profile compared to traditional VC.
Experiments were conducted to determine the thermal parameters (thermal conductivity, specific heat capacity) and heat generation rates of the batteries. These parameters were then used in Fluent simulations to optimize the aluminum plate thickness under a flow rate of 20 GPH in the cold plate. The simulation results showed that adding a 10 mm thick aluminum plate significantly improved both the average surface temperature and the temperature uniformity of the batteries. Experimental validation compared the effects of natural convection, cold plate only, ALVC + cold plate, and ALVC + aluminum plate + cold plate on the temperature distribution of individual cells and the temperature uniformity within the module. The results showed that the ALVC + aluminum plate + cold plate configuration improved average temperature rise by 58%, reduced temperature differences by 48%, and enhanced temperature uniformity within the battery module by 68.8%, compared to natural convection.
