N2 - This study explores the efficacy of Reduced Graphene Oxide (rGO) in enhancing battery thermal management for Electric Vehicles (EVs). Lithium-ion batteries (LIB), prevalent in EVs, often face heat-related challenges during their operation. The experiments are conducted with varying rGO concentrations (0.5, 1.0 and 1.5 wt. %) in conjunction with Phase Change Material (PCM), n-eicosane having a melting point of 36.5 °C. Utilizing an aluminum heat sink with pin fins of 2 mm thickness, the thermal performance is compared with a finned heat sink without PCM, with PCM and combinations of rGO with PCM. The rGO employed in this experiment is made by synthesis from graphite. Characterization studies were also carried out. The experiment involved power levels ranging from 11 to 20 W, with increments of 3 W. The results reveal that by incorporating rGO into the heat sink can reduce operating temperature, specifically with the addition of 1.0 wt. % rGO. At a power level of 11 W, to reach 55 °C, 1.0 wt. % rGO with PCM took 80 min whereas the system with and without PCM took 73 and 33 min respectively. Hence, the experiments highlight the potential of rGO in advancing battery thermal management technology.
