The escalating demand for electric vehicles and lithium‐ion batteries underscores the critical need for diverse battery thermal management systems (BTMSs) to ensure optimal battery performance. Despite this, a comprehensive comparative analysis remains absent. This study seeks to assess and compare the thermal and hydraulic performances of three prominent BTMSs: fin cooling, intercell cooling, and PCM cooling. Simulation models were meticulously developed and experimentally validated, with each
This study developed an innovative immersion battery thermal management system (BTMS) that incorporates mini-channels and metal foam to address the limitations of conventional indirect liquid-cooled BTMSs under extreme conditions. The proposed system leveraged the superior thermal conductivity of the metal foam and the structural advantages of mini-channels to enhance battery cooling and preheating performance. The results showed that under fast-charging conditions, the maximum battery temperatu

In-wheel motors (IWMs) are considered to replace centralized motors in electric vehicles due to a high efficiency. However, heat dissipation is a significant challenge in IWMs because of their limited space. In this study, a U-shaped water jacket with a guide vane design is newly proposed to improve the heat dissipation performance of IWMs. An IWM simulation model is developed and validated based on experimental data. Using six independent design variables, the multi-objective optimization is pe
Most battery thermal models have been validated at low C‐rates, often overlooking the influence of entropic heat (EH) owing to its relatively small magnitude. However, at high C‐rates, the exclusion of EH can lead to significant temperature deviations. In this context, this study investigated the influence of EH on battery temperature under various operating conditions. Experiments were conducted to determine the entropic coefficient (EC), and an electrochemical–thermal‐coupled battery model was
