UK motorway to charge moving electric carsTue, 15 Apr 2014 00:00:00 -0700
The Highways Agency is set to test wireless charging in moving electric cars on a UK motorway, according to Engineering and Technology Magazine.
This would see electric vehicles gain additional charge as they passed over wireless charging nodes embedded in the motorway’s road surface.

The concept, already used by some mobile phones and currently being trialled for static charging of electric cars, uses electromagnetic fields to pass current to batteries without the use of cables or wires.
The obvious advantage is that such a system should considerably increase the range of electric vehicles, which are currently limited by battery capacity.
A study by the North Carolina State University in the United States has already suggested that an electric car with a 100km (62 miles) conventional range could potentially travel as far as 500km (310 miles) using the system, before need to stop for a full recharge.
The exact time and location details of the UK test scheme has not been announced. But the Highways Agency has issued a set of necessary criteria for any such proposed dynamic wireless charging system.
This includes a surface that last as long as ordinary asphalt (around 16 years), offers efficient charging capability at speed, affordable maintenance and is durable when confronted by both weather and the inevitable vibrations created by road traffic.
