Thermal Behavior Enhancement of Battery Thermal Management Systems Based on Phase Change Materials via a Multitude of Strategies, A Review

Since the dawn of civilization and industrialization, the public and private transportation industry has played a prominent role in each countries’ sustainable development and no one can cast a shadow of doubt on the fact mentioned. The first generation of automobiles are run by internal combustion engines burning fossil fuel which still face serious and tough challenges due to confined oil well depletion capacity and fluctuating prices being affected by any political and economic events all over the globe. To mitigate the effect of negative facts stated, automotive engineers have been perpetually seeking for other alternatives than oil and natural gas which led them to the electrification of transportation means. The main challenge a head of electric vehicle is the remarkable heat dissipation by the battery and the higher chance of thermal explosion in higher C-rates. Searching for solutions to this problem, heat transfer engineers have come up with a novel technology to cool the battery down. They introduced phase change materials to be poured around the cells to absorb the heat and prevent thermal runaway. In this paper, the authors have tried their best to briefly summarize the PCM, and the novel methods to enhance the low thermal conductivity of the substance mentioned by some methods such as extended surfaces (fins), metal foam addition and so on.
