Recent Progresses of Battery Thermal Management Systems Based on Phase Change Materials

Battery thermal management system (BTMS) based on phase change materials (PCMs) is simple in structure while presenting outstanding performance, but the core bottleneck hindering the industrialization of which is the poor performance of PCMs’ pivotal properties. Apart from that, under extreme conditions, single passive phase change temperature‐control technology apparently could not meet the demands. Therefore, modification strategies to improve PCM's pivotal properties suitable for BTMS are thoroughly reviewed. Moreover, the optimization of as‐mentioned passive systems by integrating them with other active heating or cooling devices to obtain advanced active and passive full‐temperature responsive capability is also summarized. Profound opinions concerning about the prospect and challenges of PCM‐BTMS are given. It is expected to provide some innovative ideas for the advancement of such promising technology.
