What is it about?
As electric vehicles (EVs) grow in popularity, it's crucial to ensure there are enough charging stations in the right places. This study focuses on creating a smart, efficient plan for setting up new charging stations in Georgia. By analyzing data like traffic patterns, popular locations, and county demographics, the project aims to make EV charging convenient, accessible, and fair for everyone. The process uses advanced algorithms like DBSCAN, which identifies areas where people often go, and ray-casting, which ensures every county is considered based on its population and income levels. These tools help decide where new chargers would be most useful while avoiding overlap with existing ones. Each station is tailored to match the area's needs, with more chargers placed in busier spots.

Why is it important?
This work addresses a critical need as the world transitions to electric vehicles (EVs), a cornerstone of sustainable transportation. EV adoption is surging, but many regions lack adequate charging infrastructure, which risks slowing this transition. Ensuring that charging stations are placed where they are most needed—accessible to drivers and balanced with the power grid—is essential to support this shift while maintaining public confidence in EV reliability. This study combines advanced clustering techniques (DBSCAN) and spatial analysis (ray-casting) to create a practical and adaptable approach for optimizing EV charger placement. Unlike complex AI models, this method balances simplicity, speed, and accuracy, making it accessible even for regions with limited resources. A unique aspect of this work is its attention to socio-economic diversity. By analyzing counties' income and population data, the method ensures charging stations are distributed fairly, even in underserved communities. As governments worldwide push for EV adoption and major automakers phase out gas-powered vehicles, demand for charging infrastructure is skyrocketing. This study provides a scalable framework to address this demand, aligning with current policy and environmental goals.
Perspectives
As the sole author, writing this article was a great experience to learn more about the developing EV grid and the importance of optimal vehicle placement. It also shows that optimal placement algorithms do not need to utilize extensive preprocessing and advance Machine Learning models.
