This review provides a comprehensive overview of the technological
advancements in solar Electric Vehicle (EV) charging systems, with a particular focus
on the challenges posed by Partial Shading Conditions (PSC). As the adoption of
electric vehicles grows globally, the integration of solar power for EV charging offers
significant potential in reducing carbon emissions and optimizing energy efficiency.
The review delves into the evolution of solar PV-EV charging systems, highlighting
innovations in system designs, energy management strategies, and Vehicle-to-Grid
(V2G) technologies. A key focus is placed on the impact of shading on Photovoltaic
(PV) module performance, with an exploration of various mitigation strategies such as
advanced optimization algorithms, hybrid PV systems, and battery storage solutions.
Through a review of recent studies, it outlines the effectiveness of solar-powered
charging infrastructure, including grid-connected and off-grid systems, in diverse
environmental conditions. Despite the progress, challenges related to battery
performance, system costs, and the feasibility of large-scale deployment are discussed.
Furthermore, the review investigates the economic and environmental benefits of solarassisted EV charging, with a focus on sustainability, cost reduction, and the integration
of renewable energy sources. The chapter concludes by identifying future research
directions to address the unresolved issues surrounding partial shading, battery
degradation, and the optimization of solar charging systems for widespread adoption.
Ultimately, it emphasizes the importance of overcoming shading effects to enhance the
efficiency, reliability, and sustainability of solar EV charging systems, contributing to
the broader goals of sustainable transportation and clean energy.
