A study on lithium-ion battery thermal management system with Al2O3 nanofluids

In this study, a comparison is made with regard to cooling of 15 prismatic batteries connected in series with air, alumina nanofluid. The concentration of the nanofluid was taken as 3% and 5%, the ambient temperature was taken 295 and 300 K, the inlet velocity of the refrigerant was taken 0.01, 0.02, 0.04 m/s, and the discharge rate was taken 1 to 5 C. When the discharge rate is less than or equal to 3, the battery module remained at a safe operating temperature. As the discharge rate increased, problems began to be encountered.

Automated summary

In this study, the cooling effect of 15 prismatic batteries connected in series was compared using air and alumina nanofluid. The results showed that the nanofluid can effectively keep the battery at a safe operating temperature under certain conditions.
