DWPT Trials This Year Are Said to Be the First of Their Kind

The UK’s Highways England organization is evaluating equipment suppliers for the first-ever tests of DWPT – dynamic wireless power transfer – for electric vehicles. The technology may someday allow both consumer and commercial EVs to charge wirelessly as they are driven, allowing them to travel long distances without needing to stop.

‘The off road trials of wireless power technology will help to create a more sustainable road network for England and open up new opportunities for businesses that transport goods across the country,’ says Highways England.

The current procurement follows the recent completion of a 252-page feasibility study.

“We are investigating how we can grow the electric vehicle charging infrastructure,” Highways England chief highways engineer Mike Wilson says in an introduction to the TRL/Halcrow (Transportation Research Laboratories) report.

‘A More Sustainable Road Network’

“We’re committed to supporting the growth of ultra-low emissions vehicles on our England’s motorways and major A roads,” Wilson says in an announcement this week about the impending trials. “The off-road trials of wireless power technology will help to create a more sustainable road network for England and open up new opportunities for businesses that transport goods across the country.”

The trials are expected to begin later this year. They will involve fitting vehicles with wireless technology and testing the equipment, installed underneath the road, to replicate motorway conditions.

Highays near power lines are likely to see the first use of DWPT for EV charging.

More to Come

The current initiative, Highways England says, represents the first stage in a much larger program of work. UK Transport Minister Andrew Jones said in the announcement that it’s part of a five-year £500 million ($783 million U.S. at current rates) effort to keep Britain at the forefront of low emission vehicles technology.

TRL/Halcrow researchers investigated 17 providers of wireless power transfer technology, “eight of which has a dynamic capability.”


They evaluated EVs including the Nissan Leaf, BMW i3, Tesla Model S, Renault Zoe and Mitsubishi i-MiEV for their DWPT suitability.
