Abstract

Aluminium casings are widely adopted in electric vehicles due to their lightweight and structural efficiency. However, their thermal behaviour under protective coatings is a critical factor for battery thermal management. This study investigates the impact of three commonly used coating techniques—anodizing, cathodic electrodeposition (CED) with topcoat, and powder coating—on the effective thermal conductivity of aluminium enclosures. A controlled heating experiment was performed using a hot air source applied to a defined surface area, while temperature gradients between the inner and outer surfaces were monitored using thermocouples and thermal imaging. The analysis focuses on how coating influence heat transfer, which is essential for maintaining optimal battery operating temperatures. Experimental results demonstrate that coatings introduce thermal resistance, and the extent of this effect varies significantly with coating type. These findings provide practical insights for selecting surface treatments that balance thermal performance and durability in electric vehicle battery systems.
