Charging Forward: Mapping the Global Research Landscape of Electric Vehicle Infrastructure

A. Y. Sada

Abstract


The global transition to electric mobility necessitates a robust charging infrastructure, a topic that has seen exponential growth in academic research. To navigate this expanding landscape, this study conducts a comprehensive scientometric analysis of 4,243 documents from the Scopus database (1994–2024). Using VOSviewer, we map publication trends, collaboration networks, and the intellectual structure of the field. The findings reveal a surge in publications since 2010, with the United States, India, Germany, and China as the most prolific contributors. Co-citation analysis identifies the foundational authors, while keyword co-occurrence analysis uncovers four primary thematic clusters: (1) Charging Technology and Hardware, (2) Grid Integration and Management, (3) Optimization and Planning, and (4) Policy and Socio-economics. Furthermore, a temporal analysis of keywords highlights a clear research trajectory, shifting from foundational concepts towards emerging frontiers like machine learning and wireless power transfer. This review provides a definitive map of the EV charging infrastructure research domain, offering valuable insights for researchers and policymakers shaping the future of sustainable transportation.
