In Battery Thermal Management Systems generally the melting of the phase change material became a defiance and leading to a major confrontation for the constant heat dissipation throughout the battery thermal management system due to very low thermal conductivity of the Phase Change Material. Consequently, the hexagonal shaped fins are introduced in this paper and the research work is carried out. The Battery Thermal Management Systems with the hexagonal fin structure plunged into the Phase Change Material is compared with the Battery Thermal Management Systems without any branched or fin structure induced into the Phase Change Material. The results exemplifies that the battery thermal management system where the hexagonal fins immersed into the phase change material exhibits the superior heat transfer and melting rates of the phase change material compared to the convectional Battery Thermal Management Systems which contains the Phase Change Material but with the inaccessibility of the fin structure. In this paper, the Battery Thermal Management System with four hexagonal (honeycomb) structured longitudinal fins are provided at the axis of every 90° around the battery to maximize the surface contact area of the hexagonal fin, improving the exposure of the surface of the fin to the phase change material to generate the instant and maximized heat flow through out the phase change material compared to the longitudinal rectangular and V-shaped fin structures. The main theme of the hexagonal shaped longitudinal fin is to provide a robust heat dissipation which proportionately inflate and strengthen the battery life, life cycle and superintend the high-density charge output during the battery discharge.
