Bibliometric analysis identifies key themes in smart charging for electric vehicles, suggesting future research directions.
The significant rise of electric vehicles in urban areas calls for research on smart charging to promote electric mobility. Existing research is fragmented, focusing on single aspects of smart charging, with inconsistent findings. Thus, a bibliometric analysis was conducted to identify the key themes and propose future research agendas on smart charging for electric mobility in urban areas research to guide policy formulation and promote widespread uptake of electric vehicles. A total of 201 publications covering the period 2005 to 2025 were extracted from the Scopus database. Results revealed four key themes are used on smart charging for e-mobility in urban areas research: smart charging technologies and optimisation strategies, grid integration and vehicle-to-grid systems, renewable energy and environmental sustainability, and urban mobility systems and infrastructure development. Despite their importance, real-world testing and smarter integration with cities and grids, especially in developing countries, remain largely underexplored. Future research should focus on large-scale vehicle-to-grid integration, user behavior analysis, and coordinated planning of smart charging with urban transport and policy frameworks.
