KAIST OLEV (On-Line Electric Vehicle) to begin operation!
An On-Line Electric Vehicle (OLEV) that can charge during travel will be put into service for the first time in the world on normal roads.
From July of this year 2 OLEV buses will undergo trial operations in the city of Gumi.
The trial route spans 24km from Gumi station and the region of In-Dong and the establishment of the route is expected to be of a 4.8billion Won scale. The start of the infrastructure construction will start on February and operation will start in July.
KAIST had held sessions in October of last year to local governments and had a follow up OLEV suitability evaluation to those local governments expressing interest.
The city of Gumi was elected due to its good electrical infrastructure and an administrative willingness to match.
The OLEV developed by KAIST is an environmentally friendly vehicle that allows the transfer of electrical power using magnetic fields imbedded in the roads.
Ordinary electric vehicles require frequent visits to replenish their power which gives the OLEV a comparative advantage as it can charge while on the road. The ability to charge whilst on the road means that the OLEV requires a smaller battery than the ordinary electrical vehicle resulting in lower prices and weight.
The OLEV development commenced at KAIST in 2009 and in 2010 most of the core technologies required to realize the OLEV was developed and verified. Finally in 2012 steps were taken that will allow the commercialization of the OLEV.
And in October of last year KAIST OLEV accomplished 75% power transfer efficiency that allowed a system that can be commercialized.
The KAIST OLEV was named top 50 inventions in 2010 by Time Magazine.

New wireless charging device developed
The On-line Electric Vehicle (OLEV) developed by KAIST has made a step towards commercialization with the development of a more economic wireless charging device.
Professor Chun-Taek Rim from the Department of Nuclear and Quantum Engineering at KAIST has developed a new I-shaped wireless charging device that differs from the pre-existing rail-type electricity feeder. This device can be modularly produced and requires relatively less construction, significantly reducing the cost of implementation.
The KAIST OLEV is a new concept electric car that has a special electricity collecting device underneath it. The car’s battery is charged by magnetic fields produced from electric lines buried 15cm underneath the road. The vehicle was first tested in 2009, making it the first wireless electric car in the world. OLEV can be charged during stoppage time between traffic lights and receives real-time power when running. OLEV is currently in operation at the KAIST Munji Campus in Daejeon and is also being exhibited at the Yeosu Expo and Seoul Grand Park.
The device itself has a charging capacity of 15kW, and the electricity is supplied through an electricity feeder with a width of 80cm with a space interval of 20cm. Despite being hailed as a technological breakthrough and revolutionary concept, KAIST OLEV has been criticized for problems in commercialization, due to the difficulties in installing wires beneath existing roads, which costs a considerable amount of money.
The new I-shaped wireless charging device reduces the width of the electricity feeder by 10cm, a mere one-eighth of the size of the previous version, and greatly increases the charging power to 25kW. Furthermore, the left and right permissible space of automobiles has increased to 24cm and the magnetic field complies with the international design guidelines, making the OLEV safe for the human body.
The reduction of the width has made the mass production of modules possible, making the installation of KAIST OLEV more economical and marketable. Professor Rim emphasized that compared with the existing rail-type electricity feeder, the new technology will need only one-tenth of the construction time and 80% of the cost, significantly improving OLEV’s constructability and workability.
The research was published in the IEEE Transactions on Power Electronics last December, and Professor Rim was invited to talk at the Conference on Electric Roads & Vehicles, which was held in February in the United States, about the new technology.

KAIST Signs MOU with Macquarie for Cooperation in Green Growth Projects
KAIST and Shinhan Macquarie Financial Advisory Co. have reached an agreement for cooperation in the development and commercialization of the KAIST-led two national green growth projects, On-line Electric Vehicle (OLEV) and Mobile Harbor (MH) programs, university authorities said.
KAIST President Nam-Pyo Suh signed a memorandum of understanding with John Walker, Chairman of Macquarie Group of Companies in Korea, and Woo-Gon Hwang, Representative Director of Shinhan Macquarie Financial Advisory Co. on Wednesday, Oct. 21.
Under the agreement, KAIST and Macquarie will cooperate in developing an optimal business structure for a rapid commercialization of OLEV and MH. Specifically, Shinhan Macquarie Financial Advisory will provide financial advice, including basis financial analysis, potential investor inducement and feasibility analysis of the projects.
Shinhan Macquarie Financial Advisory Co. is a joint venture between Shinhan Financial Group of Korea and the Australia-based Macquarie Bank Group which provides global investment banking and diversified financial services.
KAIST"s OLEV is a project to develop a new growth engine for Korea and lead the future of global automotive industry. It is an entirely new concept: the electric vehicle picks up power from underground power supplier lines, while either running or standing, through the non-contact magnetic charging method.
The MH program is designed to develop a system that can load/unload containers from a containership in the open sea and deliver them to their destinations at the harbor.
The Korean government has included these KAIST projects, which both are great technical and engineering challenges, in the nation"s sustainable growth programs, providing substantial research grants. KAIST offers its advanced research capabilities for the nation"s efforts to achieve efficient, environment-friendly utilization of resources as new growth engines that spur the development of related industries and explore global markets.
