New road surface that charges you electric car!

If you’re an Indian, this post would make you feel bad. Because in India, the roads are bumpy and not well laid. In other words, having a proper road is a big thing.

Meanwhile in England, the Government organisation is beginning their tests later this year. They are about to expand the wireless charging a.k.a inductive charging with the road as the emitters and the cars as receivers. A selected number of cars will be fitted with the requisite wireless charging technology and a test road will be built to demonstrate how it is different from the smaller sub-stations.



The exact details of this technology hasn’t been confirmed yet and won’t be confirmed until a contractor is appointed. This aims to stipulate the motorway conditions of the electric drive as close as possible.

One of the problems with being on the cutting edge of electric car technology is you’re not as sure of being able to find a filling station as all the petrol-burning drivers around you. If a new road surface being trialled in the UK finds wider use, that sort of ‘range anxiety’ could be gone for good – the roads actually charge your car as you drive.

Highways England, the government organisation responsible for road infrastructure maintenance, is beginning tests later this year. A select number of cars will be fitted with the requisite wireless charging technology, and a test road will be built to show how smaller sub-stations, AC/AC converters, and power transfer loops can provide inductive charging built into the road itself.

The exact details of the technology and how it works won’t be confirmed until a contractor is appointed to set up the test route, but the aim will be to simulate motorway conditions as closely as possible. It’s not yet clear how much of a charge the tarmac is going to provide, but it would certainly increase the amount of time cars could last between full charges at home or a designated charging station.

“Vehicle technologies are advancing at an ever increasing pace and we’re committed to supporting the growth of ultra-low emissions vehicles on England’s motorways and major A roads,” Highways England chief highways engineer, Mike Wilson, said in a press statement. “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.”

It might take some time before this technology hits the roads. The trials are expected to last 18 months and then the on-road testing will begin. The tests will come after a feasibility study looking how dynamic the battery could charge of running vehicles.

Meanwhile in Korea, a similar idea is already in use where specially modified electric buses use shaped magnetic filed in resonance technology built into the road surface to receive a charge as they move along.
