Efficient and secure operation of electric vehicles relies significantly on the cooling system for lithium iron phosphate (LiFePO4) batteries, a key component in electric vehicle technology.. One of the critical challenges faced by electric vehicle is battery cooling to ensure optimal performance, extended battery life, and enhanced safety. The excessive heat generated during battery operation can lead to decrease in performance and potential safety hazards. Conventional cooling systems, such as air or liquid cooling, have limitations in terms of their cooling capacity, weight, and complexity. Therefore, there is a need to explore innovative cooling techniques that can effectively reduce the thermal issues associated with Electric Vehicles LiFePO4batteries. Employing a thermal insulating coating and phase change material at the critical thickness emerges as an innovative approach to mitigate the surface temperature of battery cells. This is evident during the charging phase, where the bare cell, Teflon-insulated, and paraffin wax-coated cells reached respective peak temperatures of 69 ˚C, 57 ˚C, and 53.3 ˚C. Notably, the Teflon-coated cell exhibited a 17.39% reduction in peak temperature compared to the bare cell, while the paraffin wax-coated cell displayed a more substantial 23.18% reduction. A similar temperature reduction trend is observed during the discharging phase of the battery cell. Utilizing insulating materials or phase change materials with a critical thickness significantly lowers surface temperatures, enhancing the safety of the battery cell and ensuring prolonged life.
