【 摘 要 】

Electric vehicles (EVs) and hybrid electric vehicles (HEVs) are a new trend for the vehicle industry, due to the environmental regulations of the internal combustion engine (ICE) and pollutant emission of transportation. However, despite being very promising, the durability of the battery, due to overheating, is still an obstacle. In particular, electric vehicle batteries are manufactured with high voltage and high capacity to ensure power and energy efficiency. For this reason, a high temperature is generated in the system, which reduces the battery performance and life cycle. In this study, three different layouts, based on a direct contact air-cooled system, are designed to compare and improve the cooling performance. Further, a battery cooling test is conducted to verify the designed model. The results show that the spoiler model reduces the maximum battery temperature by (about) 16%, and effectively improves the temperature distribution of the battery cell by (about) 65%, when compared with a conventional cooling method without a spoiler.
