Thermal management system of lithium-ion battery packs for electric vehicles: An insight based on bibliometric study

Lithium-ion batteries (LIBs) are becoming gradually common in our everyday lives, associated with the rapid growth of electric vehicles (EVs) as well as hybrid vehicles (HVs). The thermal performance of a battery pack has a significant impact on its stability, aging, and durability. Hence the thermal management system (TMS) of battery packs for EVs is one of the prominent research areas in recent years. In this study, bibliometric analysis has been conducted by using the Scopus database between the years 2000 and 2021 to assess scientific articles in the field of TMS of EV's battery packs. After two iterations, we have found 983 articles relevant to this topic. Based on the analytical findings, the TMS of LIBs has been rapidly expanding, and significant outcomes will remain to increase in the future. Only a few countries have shown their significant role in this area. Among them, China seems to be the active participation country in this research field. Tsinghua University in China and Ontario Tech University in Canada are the most renowned Universities which produce more number of individual as well as collaborative research and review articles. In comparison to other journals, SAE Technical Papers has published highest number of articles. There are nearly 15 major funding agencies that sponsored the fund for the project in this area. In that, 52 projects have been funded by the National Natural Science Foundation of China. Furthermore, a quantitative analysis has been conducted on the development trend in TMS of LIBs and will serve as an established resource for budding scholars who are interested in this research area.
