The effective operating temperature of a lithium-ion battery is usually around 30 to 40 °C. If the temperature of the battery inside the electric vehicle is higher than the specified operating range, the life and efficiency of the battery may deteriorate. Also, in worst case, excessive battery heat may cause fire or explosion of the system. Therefore, Battery Thermal Management System (BTMS) is essential to keep battery temperature within the appropriate operating temperature range. In this study, the goal is to assess the applicability of newly developed material, mainly a carbon based graphite with enhanced thermal conductivity, as a medium to move the heat away from the cell in the BTMS. To verify applicability of the new material, ANSYS Fluent was used to perform thermal transfer analysis computationally and physical experiments using a heating element were carried out to strengthen results from the numerical analysis. Based on simulation results and supporting experimental results, current research provides the basis for the possible application of the new material as a part of advanced battery pack for successful EV thermal management. As mentioned in the conclusion section, it shows a clear advantage in the weight reduction area while keeping the thermal characteristics of battery pack as stable as required for the safe operation.
