In recent years, there have been increased interests and demands on electrical vehicles (EVs) as one of the green technologies. In order to overcome the critical issues of the batteries on EV introduction, KAIST introduced the new concept of electric charging method, called OLEV<SUP>®</SUP> (On-Line Electric Vehicle). OLEV<SUP>®</SUP> technology utilizes the inductive power transfer principle, so that the EV equipped with pick-up devices can be charged while the vehicle is in motion or stationary. The charging of OLEV<SUP>®</SUP> in motion requires the powered road constructed beneath the surface of the paved road. In order to optimize the location of powered track, which affects the energy balance, it is necessary to calculate and optimize the power requirement, energy consumption and change of the battery SOC level In this paper the brief explanation of the program is introduced. This program shows the algorithm to come up the most optimized powered track installation in view of the averaged electric energy requirement and instantaneous required power for a normal vehicle operation, considering the practical road application. With the results, the proper and optimized design of vehicle electric powertrain and on-road power supply infrastructure can be achieved, which is crucially important in applying the wireless power transmission technology to future urban transportation as an eco-friendly transportation strategy.

Recently, worldwide endeavors are devoted to overcome the environmental contamination, global warming and petroleum depletion. The research and development of the eco-friendly vehicle is the one of active fields in the Industry-University-Institute Collaboration. Among the many kinds of eco-friendly vehicles, the electric vehicle is regarded as the most practical solution; however, it still has problems with its battery such weight, price and life cycle. Also, charging time, limited driving range and construction of the charging infrastructures cannot be satisfied with customers’ conveniences. OLEV<SUP>®</SUP> (On-Line Electric Vehicle) is the new concept of EV which can charge power with highly efficient pick-up device from buried power line. Based on the non-contact charging from the power line, OLEV<SUP>®</SUP> is referred as the innovative EV system to cope with the battery capacity and energy density. In this paper, OLEV<SUP>®</SUP> tram and OLEV<SUP>®</SUP> bus are introduced which have been developed by KAIST(Korea Advanced Institute of Science and Technology).
