Abstract:

The study aimed to investigate the performance of the battery thermal management when conducting a performance analysis of the BTMS, and the consequence of heat pipes on the maximum temperature of the battery cells was examined utilizing the ANSYS Fluent 2024R1 commercial CFD Package. Several important findings arose from detailed CFD analysis done in this project: Firstly, it was clear that the ability of cylindrical heat pipes to improve performance increased in line with the quantity of heat produced by the battery cells. This increase was attributed to its other part, heat pipes, through which it justified attaining the requisite temperature for phase change according to the working norm of heat pipes. In particular, the minimum temperature is attained with the use of a 30W battery system using a heat pipe with a star shape. On the other hand, the highest temperature was found during the heat generation of 80W without the heat pipe system, irrespective of the working fluid flow rate. Finally, the study emphasized the greatest need for utilising heat pipe thermal management systems where and when feasible, most significantly in battery systems that generate approximately 80W heat. The absence of such systems could result in an overheating state and all the consequent hazards to the battery shell and the system. Cylindrical heat pipes are adaptive in releasing heat as the production of heat from batteries increases. From the results obtained, it was evident that the high-power LHCP systems where heat pipe integration is not incorporated and the system generated high heat are at higher temperatures; those without heat pipe integration and low heat generation are at lower temperatures, suggesting that heat pipe thermal management is necessary in case of high heat generation for safety and reliability. In addition to the previous finding, these results provide conclusive support that the heat pipe-based TMS is vital for sustaining other critical temperature profiles needed for the electric vehicle battery pack for longest-running functionality as well as to arrest catastrophes.
