The electric vehicle market is still struggling to kick-off. It’s a bit the chicken-and-egg problem. Consumers are held back because of the lack of charging points, companies are not eager to invest in the infrastructure when there is no guarentee it will be used extensively. So that’s the moment governments should help out and that’s exactly what is happening in the UK.
As part of a master plan to get more eletric vehicles (EV’s) on the road, the UK government is investing in a charging network on all major roadways with chargers every 20 miles (32 kilometers). Later this year, a pilot project in wireless charging of electric vehicles will conclude a feasibility study of the technology commissioned by Highways England. If the results are economically viable, the technology will be build out further.
How does this wireless charging work? It’s basically the same technology as used to charge your electric toothbrush or wireless phone charging. Thanks to magnetic induction, an electric current can be induced to charge the vehicle’s batteries when it drives over elektromagnetic plates build into the road. The vehicle can charge its batteries while driving, no need for charging stops anymore. The installation of the elektromagnetic infrastructure is easier than the electrification of a road via overhead cables such as for trams.
The application of induction charging for EV’s is not new. In Gomi in South-Korea for example, two wireless-charged buses ply the train station and Dong-In line. Similar projects exist in Utrecht (the Netherlands) and Torino (Italy). But if the UK decides to build out the technology over its roadway network, we’re talking about a much bigger scale. Exciting times for electric vehicles — and their drivers– ahead!
