Another example of roadway powered electric vehicles: Online Electric Vehicle
The problem with electric cars today is the short range of driving because of the battery capacity. In addition, recharging the batteries on charging stations takes time. In a blog post published 8 July, I presented an idea developed in Sweden on roadway powered electric vehicles. In South Korea they have also been working on roadway power electric vehicles, but their idea is different.
Researchers in South Korea have developed a vehicle, called Online Electric Vehicle, which recharges while driving. The technology is already taken into use; in the South Korean city, Gumi, two electric buses are driving a 24 kilometre route, recharging the batteries as they are driving, getting electricity of the road.
The buses are powered by two electric cables that lie under the surface of the road. The electric cables create magnetic fields, which are converted into electricity by a receiver under the vehicle. The technology is called “Shaped Magnetic Field in Resonance”. According to the researchers, it is not necessary that the entire road is built with cables, 5 – 15 % of the road is sufficient (nrk.no)
The core of the idea, developed in Sweden, is to place two power lines in the road.
Which solution on eco-friendly transportation do you believe the best – the Swedish power lines or the South Korean Online Electric Vehicle?
