“…The initial temperature is set to 298.15 K. Adiabatic boundaries are applied for the upper and lower surfaces, and the surrounding surface is provided with a constant heat transfer coefficient (Wang et al , 2017). The heat generation rate at each discharge rate can be determined by the expressions given by Xu et al (2022). In the simulation process, the heat generation rate is implemented using user-defined function.…”

“…To balance the simulation time and computing resource, the time step of 1 s is selected. As shown in Figure 4(a), the results produced by the numerical simulations are compared with experimental data in terms of the battery temperature rise (Xu et al , 2022). The battery temperature rise curves under the discharging rate of 0.5, 1, 2 and 3 C are provided for the model validation.…”

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.
