In response to the growing energy crisis, increasing environmental awareness, and adverse effects of climate change, adopting renewable energy (RE) technology for electric vehicle (EV) charging has emerged as a promising solution. While EVs demonstrate high efficiency, their effectiveness in reducing greenhouse gas emissions is directly linked to the source of electricity used for charging. This review examines several key aspects of RE integration with EV charging. First, it analyzes current RE sources utilized in EV charging infrastructure and their global deployment patterns. Second, it investigates various energy storage technologies, charging systems, and intelligent grid integration methods that facilitate RE adoption in the EV sector. Third, it evaluates implemented smart charging strategies that align with current global trends in EV energy consumption. Finally, the review addresses critical challenges and opportunities in grid integration, infrastructure modernization, standardization protocols, maintenance requirements, network security, and supply chain optimization.
