A wirelessly charged electric vehicle went into service last week at the Seoul Grand Park in Gwacheon, traversing a 2.2 kilometer-long circular route through the zoo.
Known as on-line electric vehicle (OLEV), the jitney is powered by electricity from an electrical charging strip planted about 5 cm under the road surface, with a 13 cm gap between the road surface and the vehicle.
It is in pilot operation at the theme park, replacing diesel powered shuttle trains that ran on diesel fuel.
The OLEV, developed by the Korea Advanced Institute of Science and Technology (KAIST), is charged wirelessly over a 400-meter long stretch of electrical strip. A special electrical strip creates a magnetic field that generates magnetic force, which is sent wirelessly to the vehicle and converted into electricity.
Similar vehicle demonstrations from other companies have failed in the United States and elsewhere.
The first KAIST OLEV was built and the electrical strips were laid in January. Numerous safety evaluations and test runs to improve efficiency have been conducted since then. (more…)
