KAUST team models use of wireless road charging

Researchers have furthered the understanding of how wireless road charging could influence driver behaviour and city planning in a future dominated by electric vehicles (EVs).

The team at KAUST in Saudi Arabia set about this by applying statistical geometry to the analysis of urban road networks.

“Our work is motivated by the global trend of moving towards green transportation and EVs,” said postdoc Mustafa Kishk. “Efficient dynamic charging systems, such as wireless power transfer systems installed under roads, are being developed by researchers and technology companies around the world as a way to charge EVs while driving without the need to stop. In this context, there is a need to mathematically analyse the large-scale deployment of charging roads in metropolitan cities.”

Drivers may seek out wireless road charging on their commute, which has implications for urban planning and traffic control. Meanwhile, the density of wireless road charging installations in a city, and the likely time spent on and between the charging roads by commuters, could influence the size of batteries installed in EVs by car manufacturers.
