Around the world, the major automakers are developing their strategies for conductive and wireless charging technologies, with concerted efforts to establish technical standards on wireless electric vehicle charging, mainly focused on the safety considerations and inter-operability. Wireless Charging Technology and the Future of Electric Transportation covers the current status of wireless power transfer (WPT) technology and its potential applications to the future road and rail transportation systems. Focusing on the applications of WPT technology to electric vehicle charging and the future green transportation field, Wireless Charging Technology and the Future of Electric Transportation was written collaboratively by nine experts in the field, led by Dr. In-Soo Suh, a professor and researcher from the Korean Advanced Institute of Technology (KAIST). This book brings an in-depth analysis of the most important areas of interest in this new area, such as: • Working principles of wireless power transfer technology • Current technology and its projected future impact on electric vehicles • Comparison between conductive and wireless charging of electric vehicles • Introduction to dynamic wireless charging systems • Technological challenges and international technical standards activities • Applications in consumer electronics, rail, aviation, marine, and off-road transportation • Long-distance electrical energy transfer
A Power Factor Correction (PFC) converter comprises the initial stage of a grid connected on-board battery charger for electric vehicles. Generally, the control scheme for the nested PFC converter consists of two Proportional Integral (PI) controllers for maintaining the input current and the intermediate DC voltage respectively. The problem with the PI current controller is its inability to track the reference sine wave signal when there is a sudden change in load, which introduces the harmonic distortions at the input current. To overcome these issues, this paper proposes the design of a Proportional Resonant (PR) current controller for the front-end rectifier in a universal battery charger. A 1 kW PFC converter with PR controller under different load conditions is simulated and presented in this paper.
In order to capture real-time characteristics of ultracapacitors (UCs), especially for electric transportation applications, they need to be modeled dynamically. Dynamic models provide accurate estimation of UC charge/discharge responses to varied inputs. Dynamic models are useful in predicting the behavior of UCs under varied load conditions. Also, it is critical to build an accurate UC model, which can be used for tests in various power electronics/drive simulation toolboxes. This paper aims at constructing an accurate dynamic UC model, which can estimate the output voltage without the extraction of the model parameters. The critical parameters have been determined dynamically from characteristic equations. The complete dynamic model is fabricated and simulation responses to charging and discharging pulses have been presented. Finally, the results obtained from the dynamic model are compared with the output voltage estimation results obtained from the popular equivalent RC-branch model.
Over the last two decades, motor drives comprising of power electronic converters and advanced electric machines have deeply penetrated into the transportation sector, where new technologies are explored, in order to electrify various modes of transportation systems. Electric transportation puts much greater demand on power electronics than conventional fossil fuel powered automobiles. In many cases (e.g., hybrid internal combustion/electric drive vehicles), optimized power electronics suites are essential. Significant advances in power electronics and motor drives have helped reduce the cost and improve the efficiency of electric vehicles (EVs). This paper reviews on evolution and advancements of permanent magnet synchronous motor (PMSM) drive systems for EVs. The paper also discusses on multiphase PMSMs and multi-motor drive systems which can be revolutionized for future electric transportation applications.
This paper models and simulates a short-primary linear induction motor (LIM) for an electric magnetic levitation transportation system, considering LIM end effects. The three-phase LIM used in the vehicle application is modeled based on both electrical and mechanical models of a short-primary LIM. As the vehicle moves, the primary inductance of the electric LIM decreases as propulsion speed increases, which should be taken into account to achieve an accurate LIM model design. The vehicle and LIM models are implemented in Matlab/Simulink, which show the decreasing primary inductance as speed increases. A small-scale LIM drive hardware system was built using an Al rail, back iron, and permanent magnets for levitation. The simulation results and experimental results are included using the hardware prototype of the LIM drive system.
Electric transportation is the future; the role of power electronics will help achieve better performance. One of the most crucial systems in the electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) is the charging system, in which the front end ac-dc converter connects the grid and the vehicle with high power quality. In North America and Europe, all automotive companies are equipped with level I and level II residential charging for vehicles. Failure to maintain power quality will result in significant impact on customers. Therefore, the charger must achieve high efficiency, power density and low harmonic content. This paper presents a survey of different topologies of power factor correction (PFC) converters in the vehicle on-board charging system.The drawbacks for all the topologies, and their corrective actions in the PFC boost converter, are also briefly discussed.
Electric transportation systems have been one of the solutions to enhance the massive transport of passengers in large and medium size cities in developed countries. However, in some developing countries, such as Latin American countries, the electric transportation is just now searching has a solution for this problem. As a difference to the developed electric transportation systems, the introduction of electric transportation systems will be made in cities where the electric infrastructure of distribution utilities is completely developed. So, the distribution utilities of large cities without an electric transportation system require models and tools, in order to determine the electric load for the development of new massive electric transportation system in the area supplied by the utility. This paper presents a tool developed in Matlab useful to simulate urban trains systems, such as the computation of electric load as function of the type of transportation system; the train's characteristics, way path characteristics, and passengers' mobility, among other factors. The simulator estimates the electric load as function of time and computes the diversified load curves for each connection point (rectifier substations, for example) and connection point of the electric transportation system to the distribution system.
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 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 and the process of developing a commercial version is in progress. The OLEV has been considered as one of the leading green mass transportation solutions in Seoul. The OLEV solved one of the most critical barriers in the commercialization of the electric vehicle - heavy and bulky battery sizes and long charging down times - by integrating the charging system and vehicles units into one single system. This paper describes the system design and system architecture issues and presents the optimization method for design parameter selection in the integrated system. Particularly, we present the mathematical model for allocating the power transmitters and determining the battery size using mathematical optimization techniques. The goal of this paper is to present how the innovation has been created by integrating two separate systems-vehicles and charging units, as well as how the integrated system could be further enhanced with systems optimization methods.
A two-stage battery charger in battery operated electric vehicles (BEVs) and plug-in-hybrid electric vehicles (PHEVs) with wide output voltage range of 100-500 V is most suitable for all vehicle architectures. Existing battery chargers have a different limited range of output voltages of 36-48 V, 72-150 V and 200-450 V is achieved by varying the output voltage of DC/DC converters keeping a fixed voltage at DC link. A universal charger, which can address this wide range of battery pack voltages is suitable for all vehicle architectures. The most feasible way to meet this requirement of wide output voltage range is to vary the voltage at DC link with a fixed conversion voltage ratio at DC/DC converter. In this paper, we propose the use of cascaded converter in power factor correction (PFC) converters to achieve the wide DC link voltages for battery chargers. The primary focus of the paper is on the analysis and operation of boost-cascaded by buck (BoCBB) converter. The control implementation presented in the paper achieves a high input power quality, wide DC link voltages with universal input voltage ranges of 85-265 V. It also provides the degree of control freedom to operate even if the VNm (output voltage to the peak of Input) <; 0.5. Simulations of the proposed converter with 1 kW power rating are carried out in PSIM 11.0 software and the results with wide DC link voltage of 150-400 V are presented in the paper.
