This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless power transfer (WPT) technology has the potential to be a convenient and reliable charging method for the light and heavy duty electric vehicles. However, the loose coupling between the two sides results in strong near-electromagnetic fields (EMFs) around the system, which may have the possibility to impact human safety if the standard limits are exceeded. Therefore, comprehensive tests are necessary to ensure the electromagnetic fields are with in safe limits. This paper presents a test methodology for the near-field from a 25-kW WPT system from Momentum Dynamics, which is installed in a heavy-duty electric shuttle at the National Renewable Energy Laboratory (NREL). The paper describes in detail the measuring device, test setup, and conditions.

The paper describes in detail the measuring device, test setup and conditions. The misalignments between the two systems' sides are considered during the measurements. Test results for the regions of concern around and inside the bus are presented and compared with the reference levels defined by the international standards, including ICNIRP 2010 and IEEE C95.1. In addition, a finite-element model is developed for the wireless coupler and analyzed at the same conditions as the tests. Comparative analysis is presented between the simulated and experimental results. The measurements at the test points show adherence to the standard limits for the general public and occupational exposure.

This book was released on 2021-08-19 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric Vehicle Integration in a Smart Microgrid Environment The growing demand for energy in today’s world, especially in the Middle East and Southeast Asia, has been met with massive exploitation of fossil fuels, resulting in an increase in environmental pollutants. In order to mitigate the issues arising from conventional internal combustion engine-powered vehicles, there has been a considerable acceleration in the adoption of electric vehicles (EVs). Research has shown that the impact of fossil fuel use in transportation and surging demand in power owing to the growing EV charging infrastructure can potentially be minimalized by smart microgrids. As EVs find wider acceptance with major advancements in high efficiency drivetrain and vehicle design, it has become clear that there is a need for a system-level understanding of energy storage and management in a microgrid environment. Practical issues, such as fleet management, coordinated operation, repurposing of batteries, and environmental impact of recycling and disposal, need to be carefully studied in the context of an ageing grid infrastructure. This book explores such a perspective with contributions from leading experts on planning, analysis, optimization, and management of electrified transportation and the transportation infrastructure. The primary purpose of this book is to capture state-of-the-art development in smart microgrid management with EV integration and their applications. It also aims to identify potential research directions and technologies that will facilitate insight generation in various domains, from smart homes to smart cities, and within industry, business, and consumer applications. We expect the book to serve as a reference for a larger audience, including power system architects, practitioners, developers, new researchers, and graduate-level students, especially for emerging clean energy and transportation electrification sectors in the Middle East and Southeast Asia.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents assessment analysis for the human exposure to electromagnetic fields from the ground assembly (GA) of the wireless power transfer (WPT) before alignment, while the vehicle does not exist over the pad. A 25 kW WPT system from Momentum Dynamics is analyzed using finite-element software during the low power alignment operation. The same system is installed at the National Renewable Energy Laboratory (NREL) and tested at the same conditions. Good agreement is observed between the results. In addition, both results comply with standard exposure limits.

Available in PDF, EPUB and Kindle. Book excerpt: A critical review of all data relevant to the assessment of human health effects associated with exposure to electromagnetic fields in the frequency range of 300 Hz to 300 GHz. Emphasis is placed on new data that shed light on the interactions of electromagnetic fields with biological systems and on the specific biological effects and responses that result. Over 500 recent studies were rigorously assessed. Sources of exposure considered include broadcasting systems, microwave ovens, induction heating stoves, visual display units, television receivers, dielectric heaters for industrial use, radar installations, and medical devices and procedures. A chapter devoted to interaction mechanisms reviews the electrical properties of tissues and discusses direct and indirect interaction mechanisms, including the interaction of biological bodies with electrical charges induced on ungrounded or poorly grounded metallic objects such as cars, cranes, wires and fences. A review of the large body of data from cellular and animal studies considers the strength of evidence pointing to effects on the nervous, endocrine, and immune systems, on reproduction and on pre- and post-natal development. The report concludes that most of the biological effects of acute exposure are consistent with responses to induced heating. Data on human responses are assessed in the next chapter which addresses concern about the effects of locally elevated temperatures resulting from the deposition of radio frequency energy and the possible dangers, particularly for pregnancy outcome linked to the use of visual display units. The report concludes that current data provide no clear evidence of detrimental health effects in humans exposed to radiofrequency fields. The remaining chapters provide guidelines for health hazard assessment and standards for protection.

Download or read book Evaluation of Electromagnetic Measurements with Regard to Human Exposure Standards written by Sheldon Samuel Sandler and published by . This book was released on 1998 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of radio frequency (RF) and extremely low frequency (ELF) electromagnetic fields can produce biological effects that can be harmful to human health. Both thermal and field effects are possible. This report estimates the effects of human exposure to electromagnetic fields in four frequency regimes: 60 Hz. (high voltage power lines), 28 KHz. (very low frequency (VLF) communication systems extendible to 10-30 MHz range), and 900 MHz (cellular communication systems). An outline of the approach needed to analyze the 70-144 MHz communication range is given but no results were generated in this effort. The known thermal and non-thermal effects are reviewed. Hazardous exposure situations are investigated including epidemiological studies, laboratory exposure to animals and in vitro studies at the cellular level. Guidelines are suggested for the ELF, VLF and cellular telephone frequencies. The scaling of measurements is discussed along with approximate analytical results. Health standards are presented, and conclusions and recommendations are given. The report also includes an extensive bibliography. Appendix A has an evaluation of government furnished field measurements with regard to IEEE and ANSI standards. Appendix B contains one preprint and three preprints of papers supported by or related to this work.

Available in PDF, EPUB and Kindle. Book excerpt: Everyone, whether they like it or not, is exposed to electromagnetic fields, most of the time, at very low levels. In this case, they are inconsequential, but they can cause adverse health effects when they become intense enough. This topic is complex and sensitive. Covering frequencies from 0 Hz to 300 GHz, Human Exposure to Electromagnetic Fields provides an overview of this vast topic. After a reminder of the concepts of electromagnetic fields, the author presents some examples of sources of radiation in daily life and in the industrial or medical sectors. The biophysical and biological effects of these fields on the human body are detailed and the exposure limits are recalled. The exposure assessment and the implementation of the appropriate regulation within companies are also covered. Technically and practically, this book is aimed at people with a scientific background, risk prevention actors, health physicians, especially occupational doctors, and equipment designers.
