Analysis of the Temperature Reached by the Traction Battery of an Electric Vehicle during the Drying Phase in the Paint Booth.

Lithium-ion battery pack performance, safety, and lifespan are significantly influenced by temperature, yet little research has focused on the specific effects of temperature during the drying phase in paint booths. This study aims to analyse how drying temperatures affect battery modules compared to operational conditions (e.g., driving, charging) and to analyse the influence of the battery state of charge on the temperature reached by the traction battery during the drying phase. Various temperature measurement methods, including diagnostic equipment and thermocouples, were employed to conduct tests. Results indicate that the battery pack temperature during the drying phase remains below 60 °C. Comparisons with temperature measurements in other scenarios (e.g., charging, high-temperature parking) show significantly higher temperatures, highlighting the relatively low impact of paint booth drying temperatures on battery thermal management.
