The purpose of a battery thermal management system (BTMS) is to maintain the battery safety and efficient use as well as ensure the battery temperature is within the safe operating range. The traditional air-cooling-based BTMS not only needs extra power, but it could also not meet the demand of new lithium-ion battery (LIB) packs with high energy density, while liquid cooling BTMS requires complex devices to ensure the effect. Therefore, phase change materials (PCMs)-based BTMS is becoming the trend. By using PCMs to absorb heat, the temperature of a battery pack could be kept within the normal operating range for a long time without using any external power. PCMs could greatly improve the heat dissipation efficiency of BTMS by combining with fillers such as expanded graphite (EG) and metal foam for their high thermal conductivity or coordinating with fins. In addition, PCMs could also be applied in construction materials, solar thermal recovery, textiles and other fields. Herein, a comprehensive review of the PCMs applied in thermal storage devices, especially in BTMS, is provided. In this work, the literature concerning current issues have been reviewed and summarized, while the key challenges of PCM application have been pointed out. This review may bring new insights to the PCM application.

Abstract Electric vehicles are being developed as a crucial tool in the fight against global warming and car pollution. As a result, battery heat management is critical for optimal operation in all climates in electric vehicles (EVs) and hybrid electric vehicles (HEVs). Extreme or higher temperatures may cause the battery’s maximum voltage to drop and its durability to deteriorate. An effective battery cooling system is required for the safe operation of electric vehicles throughout their lifecycle. The current work involves the simulation of a battery thermal management system that employs nano-enhanced phase change materials (NEPCM). Ansys Fluent is used to conduct the numerical analysis. To test the thermal performance, paraffin wax is used as the base fluid, into which various combinations of nanoparticles such as Copper Oxide, Copper, and Multi Walled Carbon Tube (MWCNT) are disseminated. The parametric study is carried out by altering the battery temperature and nanoparticle volume fraction. The findings show that at large particle volume fractions, the battery system’s heat transmission properties are greatly improved. The findings of this study will aid in the identification of optimal NEPCMs with increased thermal performance.

Thermal management in an electric vehicle is important to extend the life of the battery. This paper is about modelling and analysis of a 6-kW battery module for improving the thermal performance of the lithium ion battery in electric vehicles with PCMs (phase change materials). For a battery thermal management system, we considered phase change materials such as RT15 (Rubitherm15), RT31, EG5 (Expanded Graphite5), and EG26 PCMs with different thermal properties. The ambient temperature conditions range considered was over 40 °C and below −10 °C, also tested on the hot and cool soaking conditions. The lithium polymer pouch single battery was designed and simulation analysis was performed with and without PCMs to enhance heat transfer rate. The simulation and experiment results on a single battery were satisfied to control the battery temperature within the safe operating conditions. Hence the proposed battery thermal management system (BTMS) was applied on a 6-kW battery pack. The design of the battery module was done in AUTOCAD and analysis was done in ANSYS CFD (computational fluid dynamics) software tool.
