Abstract The production of alternative clean energy vehicles provides a sustainable solution to the transportation sector. An efficient battery cooling system is necessary for safer usage of electric cars during their life cycle. The current work presents a novel modified battery module configuration employing two-layer nanoparticle enhanced phase change materials (nePCM). The design suggests m × n × p arrangement where m denotes the number of Li-ion 18650 cells, n and p refer to the number of primary containers (filled with nePCM1) and secondary containers (filled with nePCM2). Each Li-ion cell was allowed to discharge at 3C condition for two different configurations: 7×7×1 and 7×1×1. The study involves a cooling performance comparison of proposed battery thermal management systems (BTMS) at an ambient temperature ranging from 30°C to 40°C with external natural convection conditions. The transient development of heat in batteries and the melting behavior of nePCMs shows better cooling performance for the 7×7×1 case. BTMS based on 7×7×1 configuration maintains the cell temperature below 46°C with combined nePCM and external natural convection cooling even at the hot ambient temperature of 40°C.
