South Korea tests 'electric road' for public buses
GUMI, South Korea (AFP) - A South Korean city has begun testing an "electrified road" that allows electric public buses to recharge their batteries from buried cables as they travel.
The Korea Advanced Institute of Science and Technology (KAIST), which developed the system, said on Thursday it would be tested over the next four months on a 24km route in the southern city of Gumi.
Pick-up equipment underneath the bus, or Online Electric Vehicle (OLEV), sucks up power through non-contact magnetic charging from strips buried under the road surface.
It then distributes the power either to drive the vehicle or for battery storage As a result it requires a battery only one-fifth the size of conventional electric vehicles.
