Abstract:
The driving force of an electric traction vehicle depends on the vehicle's power and the amount of electricity consumed. However, a particularly important parameter in the 3 kV DC traction is the voltage on its pantograph, which closely connects the traction vehicle and the power system. In turn, the voltage level depends on the power supply parameters of the railway line and the quantity as well as quality and location of other electric traction vehicles in the considered area. The article presents a digital model of movement for electric traction vehicles in the given power supply area.

Abstract:
With the world seeking ways to cope with climate change, the interest in and demand for electric vehicles are increasing as part of the efforts to resolve the issue of fine dust, especially in South Korea. The Korean government has consistently announced plans to promote electric vehicles as a means of transportation by providing benefits such as subsidies for electric vehicle purchase and expansion of charging infrastructure. Meanwhile, as electric vehicles continue to grow in number, the energy industry has become attentive to its role as a resource for power generation through vehicle to grid technology. This study analyzes electric vehicle consumer preferences using the discrete choice experiment (DCE) and found that there exists a clear nested structure in Korean consumers’ choice of vehicle. The study also estimates the amount of vehicle to grid electricity supply in the power market and calculates not only national but also individual economic benefit of electric vehicle owners participating in vehicle to grid services based on the estimated amount of electricity supplied. The results of scenario analysis indicate that the estimated electric vehicle supply in Korea will be about 560,000 units cumulatively and that the vehicle to grid electric vehicle power supply scale will reach 1.81 GW by 2030. The estimation shows that the economic benefit of vehicle to grid at the national power market level is 50.9 billion KRW per year, while the economic benefit at an individual level (per vehicle) is 104,151 KRW.

Abstract:
Introduction. In linear traction drives of high speed vehicles moving with velocities about 350 - 450 km/h it is expedient to use synchronous motors with stator winding located on track structure and constant magnetic field sources (permanent magnets, superconducting windings or bulk superconductors) located on the vehicle. Such high speed traction system does not require the moving contact for its power supply and it means a considerable advantage of system. Lack of a moving contact on the vehicle involves also the use of contactless system for auxiliary power supply. Purpose. The purpose of the paper is to analyze the versions of contactless auxiliary energy consumers power supply of high speed maglev vehicles with synchronous traction motors. Method. Weight, size and energy parameters of maglev vehicles power supply sources for auxiliary consumers are discussed and their areas of use are analyzed. Results. For contactless power supply of auxiliary energy consumers of maglev vehicles with electrodynamic suspension it is expedient to use linear induction generators and rechargeable batteries. For maglev vehicles with electromagnetic suspension it is expedient to use linear generators, linear transformers and rechargeable batteries. Practical significance. Results may be used for creation of national commercial high speed maglev transport. Conclusion. The choice of combination of power supply sources for auxiliary consumers is determined by vehicle magnetic suspension type. For vehicles with electromagnetic suspension it is expedient to use linear transformers, linear induction generators and rechargeable batteries. For vehicles with electrodynamic suspension use superconducting magnetic systems it is expedient to use linear generators and rechargeable batteries.

Abstract:
Certified electric vehicle power converters can inject DC current into the AC grid if they fail. Verification of DC injection by electric vehicle supply equipment can be a cost-effective extra measure to ensure power quality from a variety of plugged-in electric vehicles. As electric vehicle supply equipment typically performs high-accuracy revenue energy metering, we propose that measurement of AC current and DC injection with a single sensor is the most economically efficient design. This article presents an integrated shunt current sensing system with separation of AC and DC signals for concurrent revenue metering and DC injection detection. It also shows how the combined sensor is integrated into 19.2 kW single-phase electric vehicle supply equipment, and outlines how the design would be extended to 100 kW three-phase electric vehicle supply equipment. The prototype can detect DC injection of ≥400 mA in an AC current up to 80 A in accordance with the IEEE 1547-2018 standard. The prototype can also conduct revenue metering within the 1.0 accuracy class. The prototype does not have high power dissipation at high currents typical for shunt systems. Finally, the prototype is less costly than common electric vehicle supply equipment revenue metering CT systems with the addition of the popular Hall-effect sensor.

The purpose of this thesis was to construct and seal air and containment tanks and other parts for a constant buoyancy power supply for an Autonomous Underwater Vehicle, or AUV. While multiple materials and techniques were considered for construction, the final tanks were made using lost foam molds and epoxy resin. This secondary purpose of this thesis was to provide a detailed description of how to create fiberglass parts, especially custom designs with challenging shapes. Molds were made using a variety of techniques, with best results achieved using a hot wire. Most parts were finished by sanding and using a filler coat, though one of the tanks was left unfilled for transparency. The tanks were machined, and the foam removed, and valve, sensor and rail mounts were made and attached.

Abstract:
Smart grid has been described as the Energy Internet: Where Energy Technology meets Information Technology. The incorporation of such technology into vast existing utility infrastructures offers many advantages, including possibilities for new smart appliances, energy management systems, better integration of renewable energy, value added services, and new business models, both for supply- and demand-side management. Smart grid also replaces aging utility technologies that are becoming increasingly unreliable, as the average ages for many critical components in utility systems now exceed their original design lives. However, while smart grid offers the promise of revolutionizing utility delivery systems, many questions remain about how such systems can be rolled out at the state, regional, and national levels. Many unique regulatory and market structure challenges exist, which makes it critical to pick the right technology for the right situation and to employ it in the right manner. Technology Roadmapping may be a valuable approach for helping to understand factors that could affect smart grid technology and product development, as well as key business, policy and regulatory drivers. As emerging smart grid technologies are developed and the fledgling industry matures, a critical issue will be understanding how the combination of industry drivers impact one another, what barriers exist to achieving the benefits of smart grid technologies, and how to prioritize R&D and acquisition efforts. Since the planning of power grids often relies on regional factors, it will also be important investigate linkages between smart grid deployment and regional planning goals. This can be used to develop strategies for overcoming barriers and achieving the benefits of this promising new technology. This research builds upon existing roadmapping processes by considering an integrated set of factors, including policy issues, which are specifically tuned to the needs of smart grids and have not generally been considered in other types of roadmapping efforts. It will also incorporate expert judgment quantification to prioritize factors, show the pathways for overcoming barriers and achieving benefits, and discussing the most promising strategies for achieving these goals.

Abstract:
Research and prototyping of a fuel cell stack system for micro aerial vehicles (MAVs) was conducted by Virginia Tech in collaboration with Luna Innovations, Inc, in an effort to replace the lithium battery technology currently powering these devices. Investigation of planar proton exchange membrane (PEM) and direct methanol (DM) fuel cells has shown that these sources of power are viable alternatives to batteries for electronics, computers, and automobiles. However, recent investigation about the use of microtubular fuel cells (MTFCs) suggests that, due to their geometry and active surface areas, they may be more effective as a power source where size is an issue. This research focuses on hydrogen MTFCs and how their size and construction within a stack affects the power output supplied to a MAV, a small unmanned aircraft used by the military for reconnaissance and other purposes. In order to conduct this research effectively, a prototype of a fuel cell stack was constructed given the best cell characteristics investigated, and the overall power generation system to be implemented within the MAV was modeled using a computer simulation program. The results from computer modeling indicate that the MTFC stack system and its balance of system components can eliminate the need for any batteries in the MAV while effectively supplying the power necessary for its operation. The results from the model indicate that a hydrogen storage tank, given that it uses sodium borohydride (NaBH4), can fit inside the fuselage volume of the baseline MAV considered. Results from the computer model also indicate that between 30 and 60 MTFCs are needed to power a MAV for a mission time of one hour to ninety minutes, depending on the operating conditions. In addition, the testing conducted on the MTFCs for the stack prototype has shown power densities of 1.0, an improvement of three orders of magnitude compared to the initial MTFCs fabricated for this project. Thanks to the results of MTFC testing paired with computer modeling and prototype fabrication, a MTFC stack system may be possible for implementation within an MAV in the foreseeable future.

Abstract:
Li-ion batteries have become one of the chosen energy storage devices that are used in applications such as power tools, cellular phones and electric vehicles (EV). With the demand for portable high energy density devices, the rechargeable Li-ion battery has become one of the more viable energy storage systems for large scale commercial EVs because of their higher energy density to weight or volume ratio when compared to other current commercial battery energy storage systems. Various safety procedures for the use of Li-ion batteries in both consumer and EV applications have been developed by the international associations. The test procedures studied in this dissertation demonstrated the importance of determining the true capacity of a cell at various discharge rates. For this, the well known Peukert test was demonstrated. The study also showed that cells with different battery geometries and chemistries would demonstrate different thermal heating during discharge and slightly different Ragone results if different test methods were used as reported in the literature. Accelerated ageing tests were done on different cells at different Depth-of-Discharge (DoD) regions. The different DoD regions were determined according to expected stresses the electrode material in a cell would experience when discharged to specific DoD that follows the discharge voltage profile. Electrochemical Impedance Spectroscopy (EIS) was used to measure various electrochemical changes within these cells. The EIS results showed that certain observed modelled parameters would change similarly to the ageing of the cell as it aged due to the accelerated testing. EIS was also done on cells at different State-of-Charge (SoC) and temperatures. The results showed that EIS can be used as an effective technique to observe changes within a Li-ion cell as the SoC or temperature changed. For automotive vehicles that are powered by a fuel cell or battery, a supercapacitor can be coupled to a battery in order to increase and optimize the energy and power densities of the drive systems. A test procedure in the literature that evaluated the use of capacitors with Pb-acid batteries was applied to Li-ion type cells in order to quantify the increased power due to the use of a supercapacitor with a Li-ion cell. Both a cylindrical LiCoO2 cell and a VRLA Pb-acid cell showed some additional charge acceptance and delivery when connected to the supercapacitors. A LiMn2O4 pouch cell showed significant charge acceptance and delivery when connected to supercapacitors. The amount of additional charge acceptance and delivery of the different combinations could be explained by EIS, in particular, the resistance and capacitance of the cell in comparison to the combination of the cell and supercapacitor. A large capacity LiCoO2 cell showed high charge acceptance and delivery without connection with a supercapacitor. The study proved that EIS can be used to model the changes within cells under the different conditions and using different test procedures.

Abstract:
In a smart city, it is vital to provide a clean and green environment by curbing air pollution and greenhouse gas emissions (GHGs) from transportation. As a recent action from many governments aiming to minimize transportation’s pollution upon the climate, new plans have been announced to ban cars with gas engines throughout the world. Therefore, it is anticipated that the presence of electric vehicles (EVs) will grow very fast globally. Consequently, the necessity to establish electric vehicle supply equipment (EVSE) in the smart city through public charging stations is growing incrementally year by year. However, the EV charging process via EVSE which is primarily connected to the power grid will put high pressure upon the centralized power grid, especially during peak demand periods. Increasing the power production of power grid will increase the environmental impact. Therefore, it is fundamental for the smart city to be equipped with a modern power grid to cope with the traditional power grid’s drawbacks. In this thesis, we conduct an in-depth analysis of the problem of EVs’ interaction with the modern power grid in a smart city to manage and control EV charging and discharging processes. We also present various approaches and mechanisms toward identifying and investigating these challenges and requirements to manage the power demand. We propose novel solutions, namely Decentralized-EVSE (D-EVSE), for EVs’ charging and discharging processes based on Renewable Energy Sources (RESs) and an energy storage system. We present two algorithms to manage the interaction between EVs and D-EVSE while maximizing EV drivers’ satisfaction in terms of reducing the waiting time for charging or discharging services and minimizing the stress placed on D-EVSE. We propose an optimization model based on Game Theory (GT) to manage the interaction between EVs and D-EVSE. We name this the decentralized-GT (D-GT) model. This model aims to find the optimal solution for EVs and D-EVSE based on the concept of win-win. We design a decentralized profit maximization algorithm to help D-EVSE take profit from the electricity price variation during the day when selling or buying electricity respectively to EVs or from the grid or EVs as discharging processes. We implement different scenarios to these models and show through analytical and simulation results that our proposed models help to minimize the D-EVSE stress level, increase the D-EVSE sustainability, maximize the D-EVSE profit, as well as maximize EV drivers’ satisfaction and reduce EVs’ waiting time.

Abstract:
Es werden Möglichkeiten untersucht, das Kaltstart- und Warmlaufverhalten von Ottomotoren mit Sekundärlufteinblasung zu optimieren. Das für die Untersuchungen eingesetzte, innovative Sekundärlufteinblasesystem mittels Sekundärluftlader weist aufgrund der Baugröße, des Gewichts, der Leistungsfähigkeit und insbesondere der einfachen, thermodynamischen Betätigung Potenziale auf, die bisher eingesetzte Sekundärluftpumpe zu ersetzen. Den experimentellen Untersuchungen wurde die Entwicklung der Abgasgesetzgebung sowie eine theoretische Betrachtung der Entstehungsmechanismen von Abgasemissionen vorangestellt. Mittels eines Simulationsmodells werden die Abhängigkeiten des Sekundärluftladers von den motorischen Randbedingungen abgebildet. Somit kann eine Vorauswahl für das Luftmassenförderverhalten des Sekundärluftladers bei unterschiedlichen Einsatzbereichen getroffen werden. Die im Start- und Warmlauf, ebenso im Lastwechsel, gemessenen Ergebnisse wurden zur Analyse der Emissionsverbesserungsmechanismen eingesetzt. Insbesondere der Einblasezeitpunkt der Sekundärluft und das Hochlaufverhalten des Sekundärluftsystems zeigen einen enormen Einfluss auf die Höhe der Rohemissionen. Eine Gegenüberstellung aller gemessenen Varianten mit Sekundärluftpumpe und Sekundärluftlader zeigt einen deutlichen Emissionsvorteil des Sekundärluftladersystems. Zusätzlich bewirkt der Sekundärluftlader, durch die Bordnetzentlastung eine Motorlastabsenkung bei verbessertem Ansprechverhalten und höherem Sekundärluftmassenstrom. Ergebnis ist eine Verringerung der HC-Rohemissionen zwischen 20% und 30%. Die Vorteile im Gewicht und Bauvolumen sowie der geringere Verkabelungsaufwand runden die deutlichen Vorteile des Sekundärluftladers gegenüber der Sekundärluftpumpe ab. Durchgeführte Untersuchungen bei Tieftemperatur (-7°C) und unter Höhenbedingungen haben ebenfalls Vorteile gegenüber der Sekundärluftpumpe ausgewiesen. Die theoretische Abschätzung des Einsatzfeldes für den Sekundärluftlader ist ab einem Hubraum von 1,2°l Hubraum durchgeführt und als positiv bewertet worden
The paper investigates possible ways of optimizing the cold-start and warm-up performance of gasoline engines with secondary air injection. Due to its size, weight, performance capability, and especially its simple, thermodynamic operation the innovative secondary air injection system used for the investigations and featuring a secondary air charger has the potential to replace the secondary air pump used to date. The experimental investigations are preceded by the development of exhaust emission legislation and a theoretical analysis of the process leading to exhaust emissions. A simulation model is used to illustrate the dependencies of the secondary air charger on boundary engine conditions. Consequently it is possible to make a preselection for the air mass conducting properties of the secondary air charger in various fields of application. The results obtained by measurement in starting, warm-up, and in load changes, were used to analyze the emission improvement processes. The level of raw emissions is affected enormously by the time of injection of secondary air and the acceleration performance of the secondary air system. A comparison of all the measured variants with the secondary air pump and secondary air charger indicates that the secondary air charger system has a distinct emission advantage. In addition, by relieving the vehicle power supply the secondary air charger brings about a reduction in engine load, improved response, and higher secondary air mass flow. The result is a 20% to 30% reduction in raw HC emissions. The significant advantages over the secondary air pump are rounded off by benefits in terms of weight and bulk volume and a reduction in the amount of wiring. Tests conducted at low temperature (-7°C) and under high altitude conditions have also indicated advantages over the secondary air pump

Abstract:
Cette thèse traite de la conception d’un convertisseur DC / DC destiné aux véhicules électriques et hybrides (2,5 kW, 400V/14V, 250kHz). Dérivé de la topologie LLC à résonance, ce convertisseur bénéficie des nombreux avantages propres à cette structure particulière. C’est ainsi que le prototype réalisé présente un rendement très élevé, une densité de puissance très forte avec des perturbations EMI très réduites. La première partie de cette thèse est consacrée à l’analyse théorique du circuit LLC afin de dégager un modèle de conversion et une stratégie de contrôle adaptée à l’application visée. Afin de conserver un rendement important sur une large plage de charge, une structure basée sur la mise en parallèle de deux modules LLC est proposée. Une nouvelle stratégie de contrôle à deux boucles est également proposée pour équilibrer le courant entre les deux modules. La seconde partie de la thèse fait appel à la simulation et à l’expérimentation. Il s’agit de minimiser la masse et l’encombrement tout en maximisant le rendement. Un composant magnétique spécial est conçu puis dimensionné pour intégrer le transformateur et diverses inductances de résonance. Ce convertisseur met également en œuvre un système de redressement synchrone robuste avec une compensation de phase, un module de puissance avec une résistance thermique très faible et un système de refroidissement efficace par air. Le rendement maximal mesuré est 95%. Le rendement demeure supérieur à 94% sur une plage de puissance s’étalant de 500 W à 2 kW. La densité de puissance est 1W/cm3. La CEM du convertisseur est développée dans cette thèse
In this dissertation, a 2.5kW 400V/14V, 250kHz DC/DC converter prototype is developed targeted for electric vehicle/hybrid vehicle applications. Benefiting from numerous advantages brought by LLC resonant topology, this converter is able to perform high efficiency, high power density and low EMI. A first part of this dissertation is the theoretical analysis of LLC: topology analysis, electrical parameter calculation and control strategy. To arrange high output current, this thesis proposes parallel connected LLC structure with developed novel double loop control to realize an equal current distribution. The second part concerns on the system amelioration and efficiency improvement of developed LLC. A special transformer is dimensioned to integrate all magnetic components, and various types of power losses are quantified based on different realization modes and winding geometries to improve its efficiency. This converter also implements a robust synchronous rectification system with phase compensation, a power semiconductor module, and an air-cooling system. The power conversion performance of this prototype is presented and the developed prototype has a peak efficiency of 95% and efficiency is higher than 94% from 500W to 2kW, with a power density of 1W/cm3. The CEM analysis of this converter is also developed in this thesis

Abstract:
When considering the main trends in the development of modern autonomous objects (aircraft, combat vehicles, motor vehicles, floating vehicles, agricultural machines, etc.) in recent decades, two key areas can be identified. The first direction is associated with the improvement of traditional designs of autonomous objects (AO) with an internal combustion engine (ICE) or a gas turbine engine (GTD). The second direction is connected with the creation of new types of joint-stock companies, namely electric joint-stock companies( EAO), joint-stock companies with combined power plants (AOKEU). The energy efficiency is largely determined by the power of the generator set and the battery, which is given to the electrical network in various driving modes. Most of the existing methods for calculating power supply systems use the average values of disturbing factors (generator speed, current of electric energy consumers, voltage in the on-board network) when choosing the characteristics of the generator set and the battery. At the same time, it is obvious that when operating a motor vehicle, these parameters change depending on the driving mode. Modern methods of selecting the main parameters and characteristics of the power supply system do not provide for modeling its interaction with the power unit start-up system of a motor vehicle in operation due to the lack of a systematic approach. The choice of a generator set and a battery, as well as the concept of the synthesis of the power supply system is a problem studied in the monograph. For all those interested in electrical engineering and electronics.
