摘要

不利的环境问题和气候变化迫使全世界转向可再生能源系统。传统的集成电路发动机是造成空气污染的主要因素，而空气污染是全球变暖的主要原因。因此，EV（电动汽车）是汽车行业的未来。电动汽车面临的重要问题是电池发热。因此，为了有效地去除电动汽车电池中的热量，我们对使用 PCM 的锂离子电池被动热管理系统进行了 CFD 分析，研究了三种不同的放电速率。与裸电池相比，在放电速率为 1.5 C、1.0 C 和 0.5 C 时，装有无源 BTMS 的电池的最大温升分别降低了 2%、2.1% 和 1%，这表明所采用的 BTMS 能有效去除电池表面的热量。

Enhancing Electric Vehicle Battery Thermal Management using Phase Change Materials: A CFD Analysis for Improved Heat Dissipation

The adverse environmental issues and climate change has compelled world to shift to renewable energy systems. Conventional IC engines are the major contributor for air pollution which is the main cause for the global warming. Therefore, EVs (Electric Vehicle) are the future of the automotive industry. The important issues faced by EVS are battery heat generation. Hence in order to remove heat efficiently from the EV battery CFD analysis of a passive thermal management system using PCM for Li-ion batteries is studied for three different discharge rates. Compared to bare cell, the cell with passive BTMS reduces the maximum temperature rise by 2%, 2.1% and 1% at discharge rates of 1.5 C, 1.0 C and 0.5 C respectively thus implying that the BTMS adopted is effective in removing heat from the surface of the cell.
