摘要

The performance of Li-ion cells differs based on the chemistry used, such as Lithium Cobalt Oxide (LCO), Lithium Iron Phosphate (LFP), and Nickel Manganese Cobalt (NMC). The present work numerically investigates the thermal performance of the three types of Li-ion cell chemistry in conjunction with natural convection air cooling (NCAC) and Lauric acid-based bio phase change material (BPCM) based cooling. The MSMD-NTGK battery module in ANSYS Fluent is employed for numerical analysis. The ambient temperature was considered as 40 °C, and 45 °C is considered as the Li-ion cell’s maximum operational temperature. The simulation was performed for three different C ratings i.e. 1C, 2C and 3C, with and without BPCM assistance under NCAC. Investigation revealed that LFP performed better in comparison to the other two counterparts in terms of maintaining the lower cell surface temperature. Results revealed that for 2C discharge rate, BPCM successfully reduced the temperature by approximately 2.7 K, 1.8 K, and 1.9 K for LCO, LFP, and NMC chemistry cells. In case of 3C discharge rate, the temperature reduction is observed as 6.3 K, 4.1 K, and 4.7 for LCO, LFP, and NMC. In conclusion, the LFP chemistry cell is performing better in terms of surface temperature growth. Furthermore, the BPCM melt fraction is also observed for 2C and 3C discharge rates for all the tested cases; the NMC chemistry cell shows maximum melt fractions.
