Salminen, Lithium ion battery production. Zhao, Thermal issues about Li-ion batteries and recent progress in battery thermal management systems: a review. This study attempted to cap the maximum temperature within permissible limits through the use of PCM cooling system.īP Energy Outlook 2035 shows global energy demand growth slowing, despite increases driven by emerging economies, Energy Outlook 2035 | News and insights | Home n.d. Furthermore, design attributes are different for the PCM cooling system in the two lithium-ion batteries owing to the shape factor. ![]() The study reveals that a cylindrical battery stores more heat at low ambient temperature conditions when compared to a prismatic battery. ![]() Both batteries were compared against a hypothetical C rate. PCM-fin assisted structure was applied in prismatic battery and a PCM jacket was incorporated in the cylindrical battery. In a desert-like condition where peak summer temperature rises to 50 ☌, electric vehicles are difficult to operate. Battery performance is closely dependent on the ambient condition. In this study, different discharge rates ranging from 1 to 5 C were considered for investigating the thermal performance of the cylindrical and prismatic lithium-ion battery. ![]() The electric vehicle drives its input energy from a lithium-ion battery pack which rests as a bed of batteries on the chassis of the vehicle. The scenario becomes intricate in hyper-ambient conditions. The temperature rises promptly with time and high discharge rates. Lithium-ion batteries possess the potential risk of thermal runaway while discharging in hostile conditions. The study presented concentrates on the thermal performance of prismatic and cylindrical lithium-ion batteries at different discharge rates.
