This paper presents the numerical study on the usage of Al 2 O 3 nanofluid-filled heat pipes in controlling the temperature of lithium-ion batteries, specifically for the application in powering the electric vehicle (EV). The heat pipes thermal management system (HPTMS) was modelled as a solid continuum body with high equivalent thermal conductivity. Thermal resistance network model was used to determine the equivalent thermal conductivity. The effect of heat inputs and the nanoparticle volume concentration on the performance of the HPTMS were studied. The simulation results were validated against previous experimental works and showed good agreement with each other. Results also indicate that by using 1.5%vol Al 2 O 3 as the working fluid in the heat pipes, the battery surface temperature and the total thermal resistance can be reduced by as much as 4.44°C (7.28%) and 15%, respectively.
