A Review on Conductive Composite for Heat Exchange in Electric Vehicle Battery Packs

ABSTRACT The most prominent transition has all to do with the electric vehicles within the evolving technological environment facing rapid advancement today. Effective thermal performance of an electric vehicle battery pack is of utmost importance, in terms of both safety and performance, longevity. In this review a context of conductive composite materials in battery heat exchange systems (BHES) is explored, thus giving indication into the importance of architecture in optimizing heat transfer within EV battery modules. The ultimate aim is to present up‐to‐date developments in material science that will improve the thermal performance of battery thermal management systems (BTMS), achieve uniform heat distribution, and increase battery efficiency. In this regard, future aspects' emphasis is put on porous foam composites incorporating phase change materials (PCM), which are highly promising in improving thermal regulation under variable operational conditions. This study is something different from previous reviews because this article particularly highlights conductive composite phase change materials in thermal regulation for EV battery packs and recent advances. The review will also give a comparative account of conventional and advanced cooling methods, the challenges of which mainly lie in material integration and costs and will point toward possible futures of research and development in thermal management strategies for EV batteries.
