Passive Thermal Regulation of Batteries

Résumé

This work delves into the investigation of a passive thermal regulation method for batteries with using phase change materials (PCM). A dynamic simulation model was developed, incorporating energy equations for both PCM and Li-ion cells, with PCM phase transition represented using the effective heat capacity method. The model was rigorously validated and employed to evaluate the efficacy of thermal control in the battery pack. The study highlights the outstanding potential of PCM as a passive thermal regulation solution for battery packs, effectively dissipating heat and lowering the maximum operating temperature of battery packs by up to 3°C. Furthermore, the integration of PCM with passive air cooling techniques, featuring an increased convective coefficient, can lead to an additional 2.5°C reduction in maximum battery temperature. These findings underscore the effectiveness of PCM in conjunction with passive cooling for enhanced battery thermal regulation.
