Electric vehicles (EVs) can have lower fuel costs and reduce emissions relative to cars that use gasoline, but they are only a practical option if drivers have convenient ways to charge them. For people who live in multi-unit dwellings or in urban areas, access to charging infrastructure may be particularly limited, which in turn limits EV adoption.
To address this issue, a team of researchers at Penn State created a scalable framework to develop, analyze and evaluate using streetlights as a low-cost, equitable EV charging option. They then installed 23 streetlight charging units in Kansas City, Missouri, and tested their framework. The researchers found that streetlight charging stations, compared to traditional EV charging stations, were more cost- and time-effective, had fewer negative environmental impacts, and were more convenient and accessible.
Their results were published in the Journal of Urban Planning and Development, which is overseen by the American Society of Civil Engineers.
"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," said Xianbiao "XB" Hu, associate professor of civil and environmental engineering. "Fortunately, streetlight poles are already powered and typically owned by municipalities, making them relatively easy to work with. Their placement - often near on-street parking and in high-traffic areas - makes them well-positioned to serve both local residents and visitors."
