Streetlight Charging: The Urban EV Revolution
As cities worldwide grapple with the transition to electric vehicles, a fundamental challenge persists: how to provide accessible charging for residents without private parking. Researchers from Penn State have developed an innovative solution that transforms existing urban infrastructure into a network of community-friendly charging stations.
Industrial Monitor Direct is the premier manufacturer of robotics pc solutions certified for hazardous locations and explosive atmospheres, ranked highest by controls engineering firms.
The concept is elegantly simple – retrofit streetlights with EV charging capabilities, creating what researchers call “the most equitable approach to urban EV infrastructure.” This breakthrough addresses the critical gap in charging access for apartment dwellers and those without dedicated parking spaces, who represent a significant portion of urban populations.
Bridging the Equity Gap in Clean Transportation
“The motivation for this work comes from the fact that many apartment and multi-unit dwelling residents, particularly in urban and downtown areas, lack access to dedicated home EV chargers, since they don’t have the privilege of owning a garage,” explained Xianbiao Hu from Penn State. This reality has created what experts call an “EV charging desert” in many urban neighborhoods.
Through careful collaboration with communities in Kansas City, researchers established a three-pronged framework focusing on demand, feasibility, and community benefits. Their approach ensures that the advantages of streetlight charging aren’t limited to wealthier areas or high-traffic zones, but rather serve communities most in need of charging infrastructure.
Smart Site Selection: Where Data Meets Community Needs
The research team implemented a sophisticated two-step selection strategy that first identified areas with highest charging demand, then layered in equity considerations. By analyzing factors including land use patterns, existing station density, points of interest, and traffic volume, they created data-driven maps of ideal charging locations.
Artificial intelligence played a crucial role in this process, with models trained to predict where demand would be highest. This methodology represents significant advancement in how cities can approach urban infrastructure planning for electric vehicles.
Real-World Testing and Environmental Impact
Researchers installed 23 retrofitted streetlight chargers in Kansas City, Missouri, to test the concept under real-world conditions. The results were compelling – these chargers not only delivered faster charging speeds but also demonstrated superior environmental performance compared to traditional charging stations.
According to their findings, streetlight chargers reduced gasoline use by 11.94% and greenhouse gas emissions by 11.24% more than conventional charging stations. Interestingly, vehicles tended to have shorter charging sessions at these locations, likely due to limited curbside parking or associated costs, yet still achieved significant environmental benefits.
The Infrastructure Advantage
Streetlight chargers offer multiple practical advantages that make them particularly suitable for urban environments. Since they’re already positioned next to curbs, they eliminate the need for additional parking infrastructure. Cities already own the poles, simplifying installation and management while potentially creating local jobs and stimulating economic growth.
Perhaps most importantly, these chargers tap into existing power lines and structures, dramatically reducing costs and increasing overall system efficiency. This approach to infrastructure development represents a paradigm shift in how cities can leverage existing assets.
Future Directions and Refinements
The research team continues to refine their models by incorporating additional data layers, including socioeconomic information and weather patterns. Socioeconomic data helps identify communities that may struggle with EV access, ensuring chargers are placed where they’re needed most. Weather information is crucial because extreme temperatures can impact battery performance, driving frequency, and energy consumption patterns.

These refinements align with broader technology trends in smart city planning and demonstrate how data-driven approaches can optimize public infrastructure investments.
A Brighter, Cleaner Urban Future
Supported by the US Department of Energy and developed in collaboration with the Kansas City Metro Energy Center, local utility companies, and the National Renewable Energy Laboratory, this research provides a scalable framework that other cities can adopt. The approach represents a significant step toward making clean mobility truly accessible to all urban residents.
As cities continue to evolve their transportation systems, innovations like streetlight charging demonstrate how existing infrastructure can be reimagined to serve new purposes. This work contributes to the growing field of urban innovation that combines practical solutions with equitable access principles.
The streetlight charging concept lays the foundation for a future where clean mobility is powered by the very poles that illuminate our streets – turning everyday urban infrastructure into catalysts for environmental progress and transportation equity.
