Abstract Electric mobility decarbonizes the transportation sector and effectively addresses sustainable development goals. A good battery thermal management system (BTMS) is essential for safe working of electric vehicles with lithium‐ion batteries (LIBs) to address runaway associated catastrophic hazards effectively. However, PCMs suffer from low conductivity issues, hence, enhancement techniques include use fins, nano‐additives, extended graphite powder, so forth. The composite phase change materials LIB widely used in while mitigating runaway, besides providing flame retardancy, thermal/mechanical stability, electrical insulation, preventing leakage. It noted that no single strategy BTMS brought down a zone temperature, hybrid BTMSs are being employed, invariably involve (PCMs) large extent. utilize CPCMs effects low‐temperature environments vibrations considering vehicle driving cycles operating conditions. observed review ultrasonic monitoring early detection internal short circuits steps towards mitigation propagation. required optimization methods, machine learning IoT tools feasible PCM based work. Present briefly describes potential methods effective utilization PCMs, comparison among different challenges solutions. highly develop compact economical better safer operation attract large‐scale commercialization vehicles.

This study aims to enhance the performance of air-cooled hybrid battery thermal management system (BTMS) by using fins under extreme discharge conditions such as 7C, 9C, and 11C. In this context, five different fin structures, Type-I (no fin), Type-II (rectangular), Type-III (extended), Type-IV (blade), Type-V (triangular), were modeled, numerical analyses developed BTMSs performed COMSOL Multiphysics software. analysis, three phase change materials (PCM-1, PCM-2, PCM-3) with thicknesses (tPCM) 4, 6, 8 mm considered, airflow was supplied at Reynolds (Re) numbers 100, 200, 400. way, effects BTMS types, tPCM, PCM air velocity on pack temperature distribution (ΔT), melting uniformity (ΔF), maximum cell (Tmax) in investigated. As a result analyses, ΔT found be 5.58 °C for case involving PCM-1 tPCM 4 PCM-2 exhibited best all types 9C. However, 11C, only PCM-3 6 could maintain Tmax 60 °C. Moreover, results obtained from analysis revealed that use significantly increased uniformity.

ABSTRACT Modern electric vehicle (EV) batteries need phase change materials (PCM) that are capable of efficient battery cooling. In this work, a composite PCM is prepared by mixing Fe 3 O 4 nanoparticles (1 wt.%) in paraffin, and the effects these on enthalpy melting point studied. It found nanoparticle additives reduce onset from 61.46°C to 57.03°C. The used for cooling module 6 substitute‐18 650 batteries, performance experimentally numerically investigated. hybrid thermal management system (BTMS) utilizing paraffin demonstrates significant reduction 11.2°C lithium‐ion (LIB) temperature compared with natural convection at heat generation rate 2W. numerical results study good agreement experimental values, modest mean absolute error 1.35°C detected between obtained simulated values. order deal low conductivity liquid after melting, investigation conducted effect graphite fin temperature. use BTMS considerably reduces LIBs difference module. simulations capture behavior phenomenon, showing evolution under constant heating. This work presents dynamic patterns along length LIB without fin, which useful effective design BTMS.
