摘要

India's transport sector is a major energy consumer, heavily reliant on fossil fuels, leading to significant CO2 emissions and a rise in harmful airborne pollutants like particulate matter and nitrogen oxides. With the growing recognition of the benefits of clean energy alternatives, the electrification of transportation is gaining momentum due to its potential to drive societal, economic, and environmental advances. Electric vehicles are emerging as viable replacements for traditional combustion engine vehicles, although they face challenges related to battery lifespan, autonomous operation, and charging infrastructure. Wireless power transfer technologies, particularly with advancements in inductive power transfer and bidirectional charging systems, offer cutting-edge solutions to these issues. By eliminating the need for direct physical connections, WPT reduces maintenance requirements and enables the use of lighter batteries, advantageous for electric transit systems where opportune, frequent stops can be used for charging. This study introduces a simulation of a WPT system incorporating a class E resonant rectifier functioning above 500 kHz to improve energy transfer efficiency. Analysis of assorted WPT configurations in this research illuminates key variables influencing system efficacy. The findings inform enhancements in WPT system optimization for robust integration with the existing EV charging landscape, emphasizing practicality and cost reduction. The simulation's results highlight WPT's capacity to bolster EV market expansion and contribute significantly to cleaner, more sustainable urban transportation solutions.
