This survey investigates the state-of-the-art in operations and systems-related studies of wireless charging electric vehicles (EVs). The wireless charging EV is one of emerging transportation systems in which the EV’s battery is charged via wireless power transfer (WPT) technology. The system makes use of charging infrastructure embedded under the surface of the road that transfers electric power to the vehicle while it is in transit. The survey focuses on studies related to both dynamic and qu

We introduce a new type of electric transit bus (ETB) system that uses the innovative wireless power transfer technology developed by the Korea Advanced Institute of Technology (KAIST), which is called on-line electric vehicle (OLEV). In the ETB system, the wireless-charging infrastructure installed under the road charges the fleet of electric buses that are operative over that road. The technology is innovative in that the battery in the bus is charged while it is moving over the charging infra

This paper presents an initial investment cost analysis of public transportation systems operating with wireless charging electric vehicles (EVs). There are three different types of wireless charging systems, namely, stationary wireless charging (SWC), in which charging happens only when the vehicle is parked or idle, quasi-dynamic wireless charging (QWC), in which power is transferred when a vehicle is moving slowly or in stop-and-go mode, and dynamic wireless charging (DWC), in which power can

The On-Line Electric Vehicle (OLEV) is an electric vehicle system is that utilizes the innovative wireless charging solution developed at Korea Advanced Institute of Science and Technology (KAIST) in South Korea. The OLEV system consists of vehicles and road-embedded power transmitters. The battery in the vehicle is charged remotely from the transmitters buried under the road and the charge can be done even while the vehicle is moving. The prototype of the OLEV has been successfully developed an

In this paper, we present an analysis to identify a sensor location for an inertial measurement unit (IMU) on the body of a skier and propose the best location to capture turn motions for training. We also validate the manner in which the data from the IMU sensor on the proposed location can characterize ski turns and performance with a series of statistical analyses, including a comparison with data collected from foot pressure sensors. The goal of the study is to logically identify the ideal l

A learning-based dynamic routing algorithm is proposed for the overhead hoist transport (OHT) systems of semiconductor fabrication facilities (fabs). An OHT system, which consists of multiple vehicles moving at high speeds on guided rails, is the primary automated material-handling system (AMHS) in a fab. Modern large-scale fabs have hundreds of vehicles moving lots between multiple processing machines. The dynamic routing method is a route guidance method that dynamically selects the best vehic

This paper introduces widely used current automated material handling systems in thin-film-transistor liquid-crystal-display (TFT-LCD) panel manufacturing systems. The automated material handling system (AMHS) in this paper refers to a hardware system that transports discrete parts from one processing machine to another. The TFT-LCD panel industry has been one of the fastest growing industries in the last decade. In particular, the process equipment for the TFT-LCD has undergone significant impr

This paper introduces the system design and integration issue of the revolutionary transportation system called On-Line Electric Vehicle (OLEV) recently developed by Korea Advanced Institute of Science and Technology (KAIST). The OLEV is an electric transportation system that utilizes an innovative wireless charging solution. The OLEV system consists of vehicle units and charging units, which are the road-embedded power transmitters. The battery in the vehicle is charged remotely from the transm
