Abstract


The widespread adoption of electric vehicles (EVs) necessitates innovative solutions for fast, efficient, and scalable charging infrastructure. The present research work aims to integrate Battery Swapping Stations (BSS) with renewable-power source (Photo voltaic system), and proposes enhanced financial models to achieve advancements in charger technology. The present approach focuses on the development of optimized LLC resonant converters with energy recovery cell (ERC) that offer high efficiency, reduced electromagnetic interference, and improved power transfer capabilities. These converters ensure compatibility with various battery chemistries while enhancing energy conversion and thermal management. Simulation and experimental results ascertain their ability to meet the fast-charging requirement of high-power EVs and reduce energy losses. The sole power source of battery operated electric vehicle (BEV) is the battery packs that are installed in the vehicle itself, thus battery depletion with progression of working duration is a critical limitation of BEV. Charging time of batteries primarily depends upon capacity and application of the battery. Longer time compels the EV to become inoperative for the time duration and consequently hinders its operational efficiency. Battery swapping provides a practical solution to address these lacunae. By quick replacement of depleted batteries with fully charged ones and consequently reduce EV downtime, economic losses, and offering a sustainable, affordable alternative to traditional fuel stations. It represents a transformative step towards more accessible and eco-friendly mobility solutions.
