Hybrid cooling based battery thermal management using composite phase change materials and forced convection

This paper investigates the thermal management performance of a novel system using phase change material (PCM) composite for Lithium-ion (Li-ion) battery in cell scale. An experimental platform was developed to study thermal phenomena in Li-ion cell. The system was designed on the basis of heat flux measurements. The cells are embedded in a PCM composite material. The assembly is lodged in an aluminum mold manufactured by 3D printing. The impact of the addition of metal foam and forced convection was evaluated. The results showed that the proposed system allows to keep the temperature of Li-ion cell around the optimal operating temperature, 25 degrees C. It's also found that the addition of an aluminum foam allows a more efficient thermal management of the cell.

Automated summary

This study investigates the thermal management of Lithium-ion batteries at the individual cell scale using a novel system with phase change material (PCM) composite. The system successfully maintained the battery temperature around the optimal operating temperature of 25 degrees Celsius and found that the addition of aluminum foam enhanced the thermal management efficiency of the cell.
