President Suh Hosted Press Conference with Seoul-based Correspondents, on March 9, 2010
President Suh Hosted Press Conference with Seoul-based Correspondents, on March 9, 2010
President Nam-Pyo Shu had a press conference with foreign correspondents based in Seoul, South Korea, on March 9, 2010 at Seoul Foreign Correspondents’ Club (SFCC).
Prior to the conference, the president and correspondents attended a ceremony for the completion of Online Electric Vehicles (OLEV) that carries passengers to look around the amusement park, Seoul Grand Park, in Gewacheon City. OLEV was developed and built by KAIST. Following President Suh’s opening speech, a questions and answers (Q&A) session between the president and reporters proceeded.
In his opening speech, President Suh said electric vehicles are an alternative to conventional automobiles with combustion engines, and in order to manufacture affordably priced electric vehicles on a large scale, their charging should be streamlined. In response, KAIST has come up with the online electric vehicle concept.
He added, without installing separate charging stations, OLEV receives electric power from the cables buried underground while driving, idling, or parking. Its connection to a power source is non-contact.
President Suh expressed his excitement for demonstrating OLEV at Seoul Grand Park that its system works as KAIST has designed and predicted. He showed his confidence that KAIST is indeed at the stage to implement OLEV in Seoul City soon and hoped to demonstrate it at the upcoming G-20 Summit to be held in November 2010 in Seoul City.
During the Q&A session, reporters cited the construction of OLEV at the amusement park and mainly asked about a possibility of its commercialization. Other topics, they also questioned about, were hurdles related to the development and commercialization of OLEV; level of cooperation received from industries and central/local governments; technological breakthroughs and accomplishments; future development plans for the commercialization; and reactions from the public and government.
Media outlets participated in the conference were Reuters, AFP, the International Herald Tribune, ABC News, Bloomberg News, Businessweek, Voice of America, Sankei Shimbun, and etc.

KAIST introduced environmentally friendly public transportation to Seoul Grand Park.
KAIST introduced environmentally friendly public transportation to Seoul Grand Park.
First step toward the commercialization of Online Electric Vehicle (OLEV)
An online electric vehicle (OLEV) developed by KAIST replaced a trackless combustion-engine train running inside Seoul Grand Park in Gwacheon City, South Korea. On March 9, 2010, Seoul City and KAIST celebrated the completion of OLEV that picks up electricity from power cables buried underground through a non-contact magnetic charging method, called electromagnetic induction. Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.
The pickup unit installed underneath OLEV collects electricity from a roadway and distributes the power either to operate the vehicle or for battery storage. Whether running or stopped, OLEV constantly receives electric power through the underground cables. As a result, OLEV mitigates the burden of equipping electric automobiles with heavy, bulky batteries—OLEV’s battery size is one-fifth that of the batteries installed in electric vehicles currently on the market.
There is no need to establish massive charging stations or to set aside much time for recharging. If the underground power lines installed on road curbs, bus stops, parking lots, and intersections, the power system could support a substantial portion of public transportation: For example, KAIST estimates that by establishing 20% of the road infrastructure for a bus route in Seoul City, the city could offer its citizens the online electric buses.
The non-contact charging of vehicles while running, idling, or parking is an important and practical technology necessary for the development of commercialized electric vehicles. This technology solves many of the issues related to the current batteries of electric vehicles, including size, expense, and repair/maintenance. In addition, non-contact charging is safer because it prevents potential electrical hazards, such as electric shock, that result from direct contact with power sources. Furthermore, it is more convenient to drive vehicles without overhead wires directly connected to power lines, as is necessary for streetcars and trams.
The recharging strips are divided into several meters of segments in length, and vehicles receive the power each time they pass over one. In other words, a sensor is affixed within each segment. When a car with the pickup equipment drives over the segment, the sensor is turned on for the car to receive electricity. This means that when a car without the pickup equipment passes over the segment, it will not collect any electricity.
The power supply via on/off switch (sensors) relieves safety concerns about electromagnetic field (EMF). Pedestrians or cars without the pickup unit will not be exposed to EMF because the sensor embedded in the segments will not work, thus no electricity generated. In addition, even under the circumstance of EMF yield, the test results for OLEV are well below the 1998 the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guideline, 62.5mG at 20khz. OLEV’s EMF test results range from 20mG (inside OLEV while running) to 50mG (around OLEV while parking).
When talking about a wireless energy transfer such as electromagnetic induction, the most critical issue is how to reserve an air gap of 12cm (in accordance with Korean law) between the surface of roads and the bottom of vehicles while having 60% power transmission efficiency or above. There was a similar research done in the US at University of Berkley—their research was considered unsuccessful because they obtained an air gap of 5-7cm with 60% maximum level of efficiency. Besides, their electromagnetic field (EMF) was quite high (2000A), and they were unable to bring down the high cost of installing power supply system. By contrast, for the first time in the world, KAIST has succeeded to obtain 12cm (and up to 17cm) of air gap with more than 70% efficiency level of power transmission. The EMF is also well below the international standard of 62.5mG. In a nutshell, KAIST has achieved a core technology in terms of capacity, efficiency, and EMF to develop electric vehicles for commercial use.
The city government of Seoul and KAIST signed a Memorandum of Understating (MOU) on the development of an online electric vehicle in August 2009. Against the backdrop of the public’s increased awareness of environmental pollution and the depletion of fossil fuels, the two organizations agreed to introduce eco-friendly vehicles to the city’s public transportation, beginning with the introduction of a trial version of OLEV to places like an amusement park, bus terminal, airport, shopping mall, and the like.
KAIST’s OLEV research team is made up of experts from a variety of fields, including electrical and electronics engineering, computer sciences, civil engineering, information technology, and mechanical engineering. OLEV’s success at Seoul Grand Park is a result of KAIST’s innovative initiatives on convergence research, and KAIST has submitted more than 120 applications for patents right in connection with the development of OLEV.
Online Electric Vehicle at Seoul Grand Park
In terms of power transmission efficiency, KAIST’s research team achieved a maximum pick-up capacity of 62kw/h, 74% with an air gap height of 13cm from a road to the bottom of a vehicle. Composed of one engine and three passenger cars, OLEV travels along a total length of 2.2km beltway. There are four sections of power supply infrastructure established on the route (Sections 1, 2, and 3: 122.5 meters long each, and Section 4: 5 meters long). The power supply cables were laid underground for a total of 372.5 meters, 16% of the total distance of the 2,200 meter route.

Reported by Hee-Bum Park (hbpark@etnews.co.kr)
"Future of Electric Automobile Glimpsed from KAIST"s Online Electric Vehicle Project," said Professor Lee.
Distinguished Professor Edward A. Lee, from the Department of Electrical Engineering and Computer Sciences, University of California in Berkeley, expressed his impressions after a ride on KAIST’s Online Electric Vehicle.
“KAIST’s Online Electric Vehicle (OLEV) really grabs my attention because the vehicle receives its needed electricity from a cable buried underground, not from batteries. Still, many challenges lie ahead for the electric vehicle to be commercialized, but I think, today, I saw the future of electric vehicles from the KAIST project,” explained Professor Lee.
Professor Lee came to Daejeon to attend the “2010 International Workshop on Information Technology (IT) Convergence,” which was held on February 19, 2010 at KAIST’s Information and Communication Convergence (ICC) Campus.
“I rode the bus and saw its instrument panel, which displays figures of electricity picked up from the ground. The bus presents the possibility of an electric car that can actually be built in the near future,” added Professor Lee.
Professor Lee, however, pointed out that a number of issues should be addressed beforehand to commercialize OLEV, such as public concerns about magnetic waves, the economic impact of laying power strips underground, and battery efficiency as an alternative to petroleum based fuel. Nonetheless, he said that given people’s increased awareness of the problems associated with CO2 emissions, OLEV’s development is timely.
“As far as I know, there has been no research in the US to develop an electric car that receives electricity from cables buried beneath the road. It is creative and ambitious for KAIST to try to find the technological breakthrough necessary for the development of electric cars,” Professor Lee stated.
Professor Lee further commented, “So far, batteries on electric cars are heavy and bulky, and they require frequent recharging. I think KAIST has provided a solution to address this issue.”
Graduating from Yale University and Massachusetts Institute of Technology (MIT), Professor Lee earned his doctoral degree in Electrical Engineering and Computer Sciences from UC Berkeley. He worked for Bell Telephone Laboratories in Holmdel, New Jersey.

World Research University Heads Discuss Challenges in Global Financial Turmoil at 2009 International Presidential Forum in Seoul
Leaders of the world"s major research universities discussed the impact of the global economic crisis on institutions of higher learning and their research activities in particular and exchanged opinions and visions on ways to increase cooperation with governments and industry at a symposium organized by KAIST Monday (Sept. 21) at the Westin Chosun Hotel in Seoul.
More than 50 participants of the 2nd International Presidential Forum on Global Research Universities represented institutions in North America, Europe, Southeast Asia, Australia, China and Japan. They were joined by 20 presidents of Korean universities and two dozens of leaders from industry and the government.
Under the main subject of "Challenges to Global Research Universities," the international symposium proceeded in four panel sessions. The subjects of each session and their keynote speakers were:
-- "Institutional Management in Times of Financial Crisis" by Kurt Kutzler, President of Berlin Institute of Technology
-- "Innovations in Education & Research" by Brian Cantor, Vice Chancellor of University of York
-- "Globalization of Institutes of Higher Learning" by Gary Schuster, Provost and Executive Vice President of Georgia Institute of Technology
-- "The Roles of Government, University and Industry in Green Technology Development" by KAIST President Nam-Pyo Suh
KAIST President Suh expressed deep gratitude to all participants for their presentations focused on how universities weathered the difficulties from the economic turmoil and how they were continuing efforts for innovation in research and education. He observed that the 2009 International Presidential Forum was again most successful and productive after the first in 2008 and offered a precious opportunity for leaders of research universities to establish effective networking among their institutions.
"The world has witnessed a global financial turmoil of unseen magnitude and many nations are still struggling under the devastating impacts. While universities were no exception in facing economic turmoil, they have realized renewed pressures and expectations from their respective communities to provide answers to the great challenges,” he said in his welcoming remarks.
"The conference I am sure will have a far-reaching influence on the course our research universities will take to shoulder greater responsibilities for building a better future of the mankind."
Some of the participants in the 2009 International Presidential Forum came to KAIST’s Daejeon campus to take part in the EEWS (energy, environment, water and sustainability) workshop which was held on Tuesday, Sept. 22.
The Chronicle of Higher Learning, the Washington-based newspaper specializing in university education, reported from Seoul that the Forum revealed that, while American universities struggle amid the harshest economic climate in a generation, institutions in much of the rest of the world are sheltered from the fallout by strong government backing.
“Delegates to a conference of university presidents (in Seoul on Monday, Sept. 22) heard that colleges in Asia and Europe are pushing ahead with expansion plans – even as their U.S. counterparts cut back.
“The 2009 International Presidential Forum… was marked by a sharp divide in the tone set by European, Asian, and U.S. college leaders. The Americans often sounded a deeply gloomy note,” The Chronicle reported. “Never before has the impact been this bad,” the paper quoted Vishwanath Prasad, vice president for research and economic development at the University of North Texas, as saying.
On the other hand, Yves Poilane, vice president of the Paris Institute of Technology, said, according to The Chronicle, “The largely state financing of most European universities has so far acted as a shelter, and higher education remains a priority for both European and French Universities.”
The Korea Herald, published in Seoul, said in its Sept. 23 editorial:
“This week in Seoul, a symposium of leaders from international and Korean research universities heard top scholars and administrators reveal how their schools have suffered through the year under reduced government subsidies and private endowments which forced them to postpone various globalization schemes and cut down on research expenditures. Applications for master"s and Ph.D. programs declined while large percentages of graduates failed to find jobs.
“With their country showing a rapid pace of recovery, universities in Korea are in a better situation than many of their overseas counterparts, especially considering the substantial government outlays for research and development in "low carbon, green growth" projects that are largely dependent on research universities. The more the government seeks their direct contributions, the harder universities should try to increase transparency and accountability in the use of taxpayer money, so as not to betray the nation"s trust in them.
“In the wake of the global economic crisis, academia, government and industry find themselves in closer ties as they share new concepts of innovation and development in a common quest for growth. The tripartite cooperation has new significance in the recovery process. To achieve any development objectives, the other two partners must prioritize the funding of universities.”

KAIST's OLEV Best Model of Creative Growth Engine
Various models of electric vehicles designed to replace the internal combustion automobiles face significant problems as they invariably failed to overcome the limitations involving lithium battery in terms of power capacity, weight, raw materal price, recharging time and preparation of charging stations. Worst of all, the limited supply of lithium will eventually raise its price sky high when all cars use lithium batteries, and the economic value of electric cars will be lost.
KAIST"s online electric vehicle project (OLEV) seeks to resolve these fundamental problems involving electric vehicles that have so far been developed. KAIST OLEV, a project to develop a new growth engine for the nation and lead the future of global automotive industry, is an entirely new concept: the electric vehicle picks up power from underground power supplier lines through the non-contact magnetic charging method, while either running or standing. This is the first eco-friendly and economic automotive system that can resolve the problems inherent to previously-developed electric vehicles, according to the KAIST OLEV Project Center.
In February 2009, KAIST researchers first proved that up to 80 percent power conveyance is possible through a gap of 1 centimeter from the power line, and in July they successfully supplied power to a bus -- up to 60 percent across a 12 cm gap from the power line embedded in the ground -- using power supply and pick-up devices they developed. In this process, KAIST has secured the core technologies for maximizing power efficiency and minimizing the cost of installing the non-contact power supply system. KAIST has established the Online Electric Vehicle Co., Ltd., to undertake business activities related to the OLEV project, including the IPR on power supply and pick-up devices, parts and accessories and commercial promotion. A demonstration event is scheduled for Aug. 13, Thursday.
The impact of the development of the OLEV technology on the energy and environment issues and the overall economy will be enormous. In case a half of the total automobiles running in Korea, or 6 million vehicles, are replaced with OLEV, electric power produced by just two of the nation"s atomic power plants will be enough to operate them all, and the nation will be able to reduce crude oil import by 35 million barrels worth U.S.$3 billion a year (supposing $80 per barrel).
Korea"s export of OLEV units will in the future surpass the present level of overseas sale of conventional cars. When nations use online electric vehicles in large numbers, their demand for CO2-free power plants will grow. Korea has cutting-edge technology in the construction of atomic power plants. As a world leader in the area of nuclear power plant, Korea will enjoy new opportunities to contribute to the global advancement of atomic power generation as well as transportation industries.
Korea still shares a small portion of the world"s automobile market estimated to worth some 2,000 trillion Korean won. But commercialization of the OLEV technology worldwide will greatly enhance Korea"s global automotive market share. Successful development of the online electric vehicle requires preemptive investment and positive support by the government for the ultimate purpose of resolving energy and environment problems.
If and when domestic enterprises secure technological supremacy in the next generation automobile market with their online electric vehicles which will replace the 100-year-old combustion engine, it will be the most desirable shortcut to raising Korea"s international competitiveness. OLEV promises to be the model of creative growth engine in the 21st century.

KAIST, CT&T Develop Multi-Energy Hybrid Electric Car
KAIST exchanged a memorandum of understanding for the development and production of a multi-energy plug-in hybrid electric car (ME-PHEV) with CT&T, an electric car maker, on Monday (June 30).
The ME-PHEV is a new vehicle model incorporating a small electric generator and solar energy as power source with conventional plug-in hybrid electric vehicle with rechargeable batteries. The new vehicle has been jointly developed by a research team led by Profs. Soon-Heung Chang and Yong-Hoon Chung, at the department of nuclear and quantum engineering, KAIST, and CT&T.
The ME-PHEV features an increased mileage, improved battery durability and better passenger convenience compared to conventional hybrid vehicles. The joint developers have applied for domestic and international patents.
Prior to the MOU signing ceremony, Prof. Chang, who is also a vice president of KAIST, had a trial ride of the vehicle for the media at the KAIST campus.
"Major car makers of the world currently focus on developing hybrid electric vehicles with battery and internal combustion engine. Compared to these cars, the ME-PHEV offers advantage in terms of reduced air pollution and lowered production costs," said Prof. Chang.
Under the agreement, CT&T will put the features of ME-PHEV into e-Zone, the company"s city-class, low-speed electric vehicle model, with a schedule go into commercial production of the car next year.
