Wireless powered ELECTRIC BUSSES launched in  SOUTH KOREA

 

KAIST, Korea Advanced Institute and Technology has established an Online Electric Vehicle(OLEV) system.It is an electric vehicle.Which energy is provided by the road while stationary or moving. The power Which is supplied to buses is by cables fixed inside thee road.As it get charging by cables but a permanent direct connection is not needed by the cables to get charge to the vehicles. For an alternative, a magnetic field is created and converted into electric energy by the devices carried on bus. 

The main advantage of this Buses is they don't required to stop  for charging. The drawback is these vehicles as they cannot ride on the side of the road that support them.

The outview of the bus are 

85% of the maximum power transmission efficiency while keeping a distance of 17cm i.e., 6.7inch between the bus floor and asphalt.

Therefore 5% to 20% of the entire road surface is to rebuilt with the embedded cables.

Formerly, this technology was successfully tested in tramcar at an amusement park in Seoul. Now TWO OLEV buses are being tested and running between the train station and indong district in the city of Gumi, SOUTH KOREA.

How the buses are getting charge???

The cables in the road only turn on when they sense an OLEV approaching and the intensity of the electromagnetic field is well within limits enforced by international EMF standards.

The buses running at the moment do not cause any problem, nearly 15 more buses are expected to  put in the operation.
