Abstract
- Purpose: The purpose of this study is to improve the thermal management of lithium-ion batteries. The phase change material (PCM) cooling does not require additional equipment to consume energy. To improve the heat dissipation capacity of batteries, fins are added in the PCM to enhance the heat transfer process. Design/methodology/approach: Computational fluid dynamics method is used to study the influence of number of vertical fins and ring fins (i.e. 2, 4, 6 and 8 vertical fins, and 2, 3, 4 and 5 ring fins) and the combination of them on the cooling performance. Findings: The battery maximum temperature can be decreased by the PCM with vertical or ring fins, and it can be further decreased by the combination of them. The PCM with eight vertical fins and five ring fins reduces the battery maximum temperature by 5.21 K. In addition, the temperature and liquid-phase distributions of the battery and PCM are affected by the design of the cooling system. Practical implications: This work can provide guidelines for the development of new and efficient PCM cooling systems for lithium-ion batteries. Originality/value: The combination of PCM and fins can be used to reduce the battery maximum temperature and temperature difference. [ABSTRACT FROM AUTHOR]
