Master Thesis Master's Programme in Industrial Management and Innovation, 60 Credits
Master Thesis Master's Programme in Industrial Management and Innovation, 60 credits Status of The Technology for Electrical Road Focusing on Wireless Charging International Outlook Thesis in Industrial Management and Innovation, 15 Credits Halmstad 2020-06-14 Padma Kumar Parameswaran Thampi, Thomas Paul Thodukulam Poulose HALMSTAD UNIVERSITY Abstract The transportation sector has a vital role in today’s society and accounts for 20 % of our global total energy consumption. It is also one of the most greenhouse gas emission intensive sectors as almost 95 % of its energy originates from petroleum-based fuels. Due to the possible harmful nature of greenhouse gases, there is a need for a transition to more sustainable transportation alternatives. A possible alternative to the conventional petroleum- based road transportation is, implementation of Electric Road Systems (ERS) in combination with electric vehicles (Evs). There are currently three proven ERS technologies, namely, conductive power transfer through overhead lines, conductive power transfer from rails in the road and inductive power transfer through the road. The wireless charging or inductive charging electric vehicles (EV) are a type of EVs with a battery which is charged from a charging infrastructure and using the wireless power transfer technology. The wireless charging EVs are classified as stationary or dynamic charging EVs. The stationary charging EVs charge wirelessly when they are parked as well as dynamic charging EVs can charge while they are in motion. Number of studies have reported that, one of the main benefits of dynamic charging is, it allows smaller as well as lighter batteries to be used due to the frequent charging using in the charging infrastructure embedded under roads. -

HAMAMCI Abstract— Electrification in urban transportation is becoming adopted in this study can be used in conversion applications to be more popular, it is also becoming a necessity due to climate made in the future. changes and sustainability issues. Trolleybuses are presenting an alternative for this purpose. Although their technology is a mature technology that has been used for decades, there are still Index Terms— Auxiliary power unit, container loading some technical problems that need to be overcome. In this study, problem, conversion, electrification, first-fit decreasing a technical method is presented for the conversion of trolleybus algorithm, trolleybus. auxiliary power units.

For forV transportation. While animals were used for this this purpose, a method is proposed and followed. At the first step purpose, a self-propelled vehicle was no more than a dream. of the implementation, real-time data has gathered from a Like with all inventions, somebody's dream came true. The trolleybus and this one round tour data is used to run on a scaled first-ever self-propelled vehicle invented by French engineer experiment. -
Sustainable Implementation of Electrified Roads: Structural and Material Analyses
Sustainable Implementation of Electrified Roads: Structural and Material Analyses Feng Chen Doctoral Thesis KTH Royal Institute of Technology Engineering Sciences Department of Civil and Architectural Engineering SE -100 44 Stockholm, Sweden TRITA-BKN. BULLETIN 144, 2016 ISSN 1103-4270 ISRN KTH/BKN/B--144--SE ISBN 978-91-7729-193-0 Feng Chen Stockholm 2016 Akademisk avhandling som med tillstånd av KTH i Stockholm framlägges till offentlig granskning för avläggande av teknisk doktorsexamen fredagen den 25 november kl. 10:00 i sal A123, KTH, Osquars backe 5, Stockholm. I Abstract In the future, roads may not only serve for vehicles mobility but could also have the capability of enabling other functions, such as Car-to-Road communication, energy harvesting, autonomous driving or on-the-road charging. These new technologies are often referred to as making the physical road infrastructure multifunctional or ‘smart’, and their applications could promote the sustainable development of society as a whole. An important feature of these smart applications is that all require an intrinsic integration of technologies into the practical roads, and their successful implementation depends significantly on a collective (system) effort. However, our current engineering and research communities do not necessarily allow for an optimal development of such integrated systems. To fill some of the knowledge gaps, this Thesis is focusing on a specific case of the electrified road (also called ‘eRoad’) that allows for on- the-road charging, in which the consequences and possible modifications of the road infrastructure are considered. Given the promise of the Inductive Power Transfer (IPT) technology for eRoad applications, the potential challenges for a successful integration of dynamic IPT technology into the physical road structure are explored extensively in this research work. -
On the Historical Development and Future Prospects of Various Types of Electric Mobility
energies Review On the Historical Development and Future Prospects of Various Types of Electric Mobility Amela Ajanovic 1,*, Reinhard Haas 1 and Manfred Schrödl 2 1 Energy Economics Group, Vienna University of Technology (TU WIEN), 1040 Vienna, Austria; [email protected] 2 Institute of Energy Systems and Electrical Drives, Vienna University of Technology (TU WIEN), 1040 Vienna, Austria; [email protected] * Correspondence: [email protected]; Tel.: +43-1-58801-370364 Abstract: Environmental problems such as air pollution and greenhouse gas emissions are caused by almost all transport modes. A potential solution to these problems could be electric mobility. Currently, efforts to increase the use of various types of electric vehicles are under way virtually worldwide. While in recent years a major focus was put on the electrification of passenger cars, electricity has already, for more than hundred years, been successfully used in some public transport modes such as tramways and metros. The core objective of this paper is to analyze the historical developments and the prospects of electric mobility in different transport modes and their potential contribution to the solution of the current environmental problems. With respect to the latter, we analyze the effect of the electricity generation mix on the environmental performance of electric vehicles. In addition, we document major policies implemented to promote various types of e- mobility. Our major conclusions are: (i) The policies implemented will have a major impact on the future development of electric mobility; (ii) The environmental benignity of electric vehicles depends to a large extent on the electricity generation mix.
