HYBRID EVAPORATIVE COOLING SYSTEM FOR EV’S BATTERIES

The growing adoption of electric vehicles (EVs) necessitates advanced thermal management solutions to address the thermal sensitivity of lithium-ion batteries (LIBs). This study introduces a hybrid evaporative cooling system designed to regulate battery temperature effectively during both driving and parked conditions. The system integrates active cooling via a closed-loop mechanism during driving, leveraging evaporative cooling and direct heat transfer for efficient thermal management without water consumption. During parked conditions, an openloop mode is employed to mitigate the impact of external heat sources, using humidified air to maintain optimal battery performance. A thermodynamic model was developed to analyze system performance, demonstrating its ability to sustain battery temperatures within acceptable limits under extreme conditions. Results show that the system minimizes energy consumption while offering environmental benefits compared to traditional cooling methods. Its hybrid operation, adaptability, and efficiency make it a promising solution for improving LIB performance and safety in diverse climates.
