- Lithium ion (Li-ion) batteries have the energy density to power PHEV’s, but large capacity packs require complex and expensive thermal management systems that circulate air or liquid over the cells. Our research group is looking at using a passive cooling solution, utilizing a matrix of graphite/phase change material (PCM). Previous studies have demonstrated that the PCM matrix is an effective thermal management system for PHEV applications and it prevents thermal runaway propagation. In this study, active cooling using liquid is compared to passive cooling with PCM under the same operating conditions and their performance is compared. The study shows that for the current work, the PCM heat sink outperforms liquid cooling (at Reynolds numbers up to 500) by maintaining a lower pack temperature with a more uniform overall pack temperature.
