Electric Vehicle: Components, Charging Infrastructure and Grid Integration Solutions | Battery Energy Storage Systems (BESS) for EV Charging Stations | Lecture 37

This lecture focuses on Battery Energy Storage Systems (BESS) for sustainable EV charging stations and their role in improving charging reliability, peak-load management, power quality, and renewable energy utilization.
The lecture covers BESS architecture, battery technologies, battery selection and safety, BESS sizing, hybrid battery–supercapacitor storage, and Energy Management Systems (EMS) for coordinated control of renewable energy, grid supply, storage, and EV charging.
A BESCOM solar-powered EV charging station case study is also discussed to understand practical solar charging operation, grid dependence, peak-load reduction, and the need for BESS integration.
