DEVELOPMENT OF EFFICIENT COOLING STRATEGIES FOR ELECTRIC VEHICLE BATTERY AND POWERTRAIN THERMAL MANAGEMENT

Abstract

The rapid growth of electric vehicles (EVs) has increased the demand for efficient thermal management systems to ensure the safe, reliable, and high-performance operation of batteries and powertrain components. Battery packs, electric motors, and power electronics generate significant heat during charging and discharging cycles, which can adversely affect efficiency, lifespan, and safety if not properly managed. Therefore, the development of advanced cooling strategies has become a critical aspect of modern electric vehicle design. This study focuses on the development and evaluation of efficient cooling strategies for electric vehicle battery and powertrain thermal management. A comprehensive thermal management framework was designed to regulate component temperatures under various operating conditions. Different cooling techniques, including air cooling, liquid cooling, phasechange materials (PCM), and hybrid cooling systems, were investigated and compared based on their thermal performance, energy consumption, and cooling effectiveness. Computational modeling and simulation techniques were employed to analyze temperature distribution, heat dissipation characteristics, and thermal stability of the battery and powertrain systems. The simulation results demonstrate that advanced liquid and hybrid cooling methods provide superior heat removal capability compared to conventional air-cooling approaches. The proposed thermal management strategy effectively maintains battery and powertrain temperatures within the recommended operating range, reducing thermal hotspots and improving overall system efficiency. Furthermore, the optimized cooling system enhances battery lifespan, operational reliability, and vehicle performance while minimizing energy losses associated with thermal regulation. The findings indicate that efficient cooling strategies play a vital role in improving the safety, durability, and energy efficiency of electric vehicles. The proposed approach offers a promising solution for next-generation EV thermal management systems and supports the development of sustainable and highperformance electric transportation technologies.
