The eMobility sector is going through its transformation phase. With the increasing focus on electric vehicle from the public and private sector, every player in the eMobility industry is working relentlessly on increasing the performance of the electric vehicle with higher efficiency, larger capacity and reduced size. The only objective of all this research and development is to make electric vehicle at par or even better than IC engines at a lower cost. High Voltage EV Batteries, being the most critical component of the electric vehicle are the ones that are focused most for capacity enhancement, performance optimization and Cost/size reduction. Researchers in the entire value chain of EV Battery, Cell, Module and Pack level are constantly working on fast charging and capacity enhancement projects. Introduction: Battery thermal management is one of the most critical aspect in the design and development of EV Batteries for fast charging and
