For EMI prediction, suppression and EMC optimization design for EVs, this book provides reference for engineers to solve EMC problems. This book is intended for senior undergraduates, postgraduates, lecturers and laboratory researchers engaged in electric vehicle and electromagnetic compatibility research.
As a part of its mission, JRC performs pre-normative research in strategically important areas, often in private-public partnership, if methodological knowledge consolidation is in reach. Specifically for road-bound electro-mobility, the JRC's European Interoperability Centre for Electric Vehicles and Smart Grids can test the electromagnetic compatibility of electric vehicles in full road simulation and in recharging, by virtue of its VeLA 9 electromagnetically semi-anechoic chamber (SAC) with integrated, filtered recharging power supplies and a shielded 4x4 roller bench. In this context, the authors accepted requests by several external vehicle manufacturers to carry out conductive and radiated emissions measurements on prototypic and series electric vehicles (EV) under charge, in accordance with national and international electromagnetic compatibility (EMC) automotive and electro-technical standards. Such measurements require the presence of dedicated EMC instrumentation and properly validated laboratory facilities, not only including the semi-anechoic chamber itself, but also antennas, shielded cablings, electromagnetic interference (EMI) receivers and line impedance stabilisation networks (LISNs) that VeLA 9 is equipped with for such purposes, all complying to the requirements of EMC regulations.
Anyone who has operated, serviced, or designed an automobile or truck in the last few years has most certainly noticed that the age of electronics in our vehicles is here! Electronic components and systems are used for everything from the traditional entertainment system to the latest in “drive by wire”, to two-way communication and navigation. The interesting fact is that the automotive industry has been based upon mechanical and materials engineering for much of its history without many of the techniques of electrical and electronic engineering. The emissions controls requirements of the 1970’s are generally recognized as the time when electronics started to make their way into the previous mechanically based systems and functions. While this revolution was going on, the electronics industry developed issues and concepts that were addressed to allow interoperation of the systems in the presence of each other and with the external environment. This included the study of electromagnetic compatibility, as systems and components started to have influence upon each other just due to their operation. EMC developed over the years, and has become a specialized area of engineering applicable to any area of systems that included electronics. Many well-understood aspects of EMC have been developed, just as many aspects of automotive systems have been developed. We are now at a point where the issues of EMC are becoming more and more integrated into the automotive industry.
This SAE Standard covers the measurement of radio frequency radiated emissions and immunity. Each part details the requirements for a specific type of electromagnetic compatibility (EMC) test and the applicable frequency range of the test method. The methods are applicable to a vehicle or device powered by an internal combustion engine or electric motor. Operation of all engines (main and auxiliary) of a vehicle or device is included. All equipment normally operating when the engine is running is included. Operator controlled equipment is included or excluded as specified in the individual document parts.The recommended levels apply only to complete vehicles in their final manufactured form. Vehicle-mounted rectifiers used for charging in electric vehicles are included in Part 2 of this series of documents when operated in their charging mode.Emissions from intentional radiators are not controlled by this document. (See applicable, appropriate regulatory documents.) The immunity of commercial mains powered equipment to overvoltages and line transients is not covered by this document.RationaleThis revision of SAE J551-1 reflects changes to existing parts of the series and the addition of a new test method.

This document specifies the general requirements, test schemes, immunity requirements and emission requirements of electromagnetic compatibility of the electric vehicle wireless power transfer system. This document is applicable to the wireless power transfer system composed of the ground devices and on-board devices, and the ground devices and electric vehicles. It is also applicable to the ground devices, on-board devices and electric vehicles (or vehicles for short) in the wireless power transfer system. The radiated emission requirements specified in this document do not apply to intentional emissions generated by radio transmitters defined by the ITU, nor do they apply to spurious emissions related to these intentional emissions.
In order to safeguard potential benefits brought by the electrification of road transport it becomes more and more important to evaluate the performance of hybrid, fully battery-powered and fuel-cell powered electric vehicles (HEVs, BEVs and FCEVs) in terms of electromagnetic emissions in charging and real-driving conditions. The present report describes the results of a test campaign conducted on a station wagon, namely a Peugeot 508 SW PHEV (hybrid plug-in vehicle) within the EC Joint Research Centre's VELA 9 laboratory, providing a semi-anechoic chamber for testing electromagnetic compatibility of all types of EVs. The vehicle was tested not only according to the UNECE Regulation n.10, but then also under more realistic driving conditions beyond the requirements of that regulation, in order to check its performance in terms of radiated emissions with regard to electromagnetic compatibility. Other tests were conducted beyond UNECE Reg. 10, in order to assess possible improvements on the current measurement procedures. The influence of different speeds, driving cycles, driving mode settings, and measurement setups on the vehicle's electromagnetic emissions was evaluated as well as a broader set of frequency ranges explored.
In recent years, power electronics have been intensely contributing to the development and evolution of new structures for the processing of energy. They can be used in a wide range of applications ranging from power systems and electrical machines to electric vehicles and robot arm drives. In conjunction with the evolution of microprocessors and advanced control theories, power electronics are playing an increasingly essential role in our society. Thus, in order to cope with the obstacles lying ahead, this book presents a collection of original studies and modeling methods which were developed and published in the field of electrical energy conditioning and control by using circuits and electronic devices, with an emphasis on power applications and industrial control. Researchers have contributed 19 selected and peer-reviewed papers covering a wide range of topics by addressing a wide variety of themes, such as motor drives, AC–DC and DC–DC converters, multilevel converters, varistors, and electromagnetic compatibility, among others. The overall result is a book that represents a cohesive collection of inter-/multidisciplinary works regarding the industrial applications of power electronics.
