Over the past decade, electric vehicle (EV) adoption has surged globally, driving a sharp increase in charging infrastructure demand. This paper reviews the worldwide growth of EV markets and the corresponding expansion of charging networks. We analyze recent data on EV stocks and sales, and document how public and private chargers have proliferated. For example, global EV stocks rose from ~1.5 million in 2018 to over 15 million by 2024. Public charging points have more than doubled since 2022, exceeding 5 million by end-2024 (International Energy Agency., 2025). The study examines regional patterns - China hosts about 65% of chargers added since 2020, Europe and North America are expanding rapidly, and emerging markets like India and Latin America are accelerating growth. It also surveys technical and policy factors: fast-charging technology improvements, smart-grid integration, and government incentives. Challenges such as high deployment costs, grid impacts, and uneven charging access are discussed. Practical data sources and case studies (e.g., smart charging experiments) illustrate real-world demand management and usage patterns. We highlight that balancing charger rollout with EV uptake is critical; globally there are on average ~10 EVs per public charger, a ratio that varies widely by country. To meet future demand, coordinated planning, standards, and investment will be needed.
