Abstract

Introduction: This study presents an innovative approach to Battery Thermal Management Systems (BTMS) for electric vehicles, specifically focusing on compact crossover designs. We propose a novel hybrid cooling system that integrates liquid cooling channels with metal foam heat dissipation. The system incorporates strategic placement of cooling passages and intelligent control mechanisms for optimal temperature regulation. Through Computational Fluid Dynamics (CFD) analysis, we demonstrate that our proposed system maintains battery temperature within optimal operating ranges (25-45°C) even under extreme conditions. Results show the system achieves an average temperature of 35°C when ambient battery temperature reaches 60°C, indicating effective thermal management capability. The paper presents the design and optimization of an innovative thermal management system for electric vehicle (EV) battery packs. The proposed design features a multi-chamber battery structure with integrated cooling channels, specifically engineered for compact crossover vehicles. The system incorporates rectangular cooling passages between battery chambers, offering enhanced thermal dissipation compared to conventional cylindrical cooling tubes. Computational fluid dynamics (CFD) simulations validate the thermal performance of the design, demonstrating improved heat transfer characteristics through the rectangular cooling channels.

Conclusions: The proposed thermal management system represents a significant advancement in EV battery cooling technology. The system's ability to maintain average temperatures of 35°C under extreme conditions (60°C) validates its effectiveness for practical applications in compact crossover electric vehicles[5].
