Comparative Study and Development of Optimized Energy Efficient Battery Thermal Management System for Electric Vehicles in India

Transportation electrification is one of the top priorities of India to curb the pollution caused by conventional vehicles. A major challenge in the commercial deployment of EV’s in India is the thermal management of high voltage battery packs. Battery pack’s temperature directly influences vehicle dynamic performance and long term durability. In this work, an optimized energy-efficient Battery Thermal Management System has been proposed, designed and developed and its feasibility analysis is performed for high ambient temperature conditions scenarios. A data acquisition system was developed for the management of different data such as temperature of battery pack, pressure difference across any component, coolant flow rate, etc. This study incorporates the concept of battery simulator instead of real batteries. The developed physical battery simulator is helpful in studying the thermal behaviour of different cell chemistries at any desired environmental conditions. The experimental setup in the lab environment has promising results in terms of feasibility and viability for extreme temperature scenarios.
