<div class="section abstract"><div class="htmlview paragraph">With the global issue of fossil fuel scarcity and greenhouse effect, interest in electric vehicles (EVs) has surged recently. At that stage, because constraints energy density battery performance degradation low-temperature conditions, mileage EVs been criticized. To guarantee performance, a thermal management system (BTMS) is applied to ensure operates suitable temperature range. Currently, industry, settled interval set as criteria positive activation, which robust but leads waste. BTMS kilowatt-level power usage under high- environments. Optimizing control strategy becomes potential solution reduce consumption overcome issues. An appropriate simulation model provides an effective tool evaluate different strategies. In this study, predictive strategy, adjusts heating or cooling thresholds dynamically utilizing predicted states, proposed. A simplified implemented Geely brand EV established using MATLAB/Simulink.

Effective thermal management is essential for the safe and efficient operation of lithium-ion battery packs, particularly in compact, airflow-sensitive applications such as drones. This study presents a comprehensive analysis 16-cell pack by exploring seven geometric configurations under airflow speeds ranging from 0 to 15 m/s integrating nano-carbon-based phase change materials (PCMs) enhance heat dissipation. A Computational Fluid Dynamics (CFD) approach was employed using Ansys Discovery Workbench 2024 R1 simulate transfer processes with high spatial resolution. Using high-fidelity 3D simulations, we found that trapezoidal wide-base configuration, combined 5-inlet 1-outlet design, achieved most balanced cooling performance across all speed regimes. configuration maintained temperatures within optimal operating range (∼45 °C) both low- high-speed conditions, maximum temperature reduction up 8.3 °C compared standard square configuration. Additionally, PCM integration extended regulation duration approximately 12.5 min, effectively buffering spikes during peak loads. These findings underscore critical role CFD-driven optimization advanced material designing high-efficiency, compact systems energy-dense drones portable electronics.
