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.

This book introduces the electromagnetic compatibility(EMC) of electric vehicle(EV), including EMC of the whole vehicle, electromagnetic interference(EMI) prediction and suppression of motor drive system, EMI prediction and suppression of DC-DC converter, electromagnetic field safety and EMC of wireless charging system, signal integrity and EMC of the vehicle controller unit(VCU), EMC of battery management system(BMS), electromagnetic radiated emission diagnosis and suppression of the whole vehicle, etc. The analysis method, modeling and simulation method, test method and rectification method of EMC are demonstrated. The simulation and experimental results are presented as tables and figures. This book is useful as reference for graduate students, senior undergraduates and engineering technicians of vehicle engineering related majors. 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.

EMC is an indispensable process throughout the design and manufacturing cycle of any electrical and electronic product. Prior to their launch on the market, these must comply and conform to a series of applicable EMC standards and regulations that aim to protect equipment against EMI. This is more than crucial to automotive EMC as it is associated with the operation of the vehicle's modules and hence the functional safety and reliability of the system against unintentional and intentional EM disturbances. This report presents and analyses the results of EMC laboratory measurements, based on CISPR 12 and IEC 61851-21-1, of a prototype solar-charged electric race-car during driving and charging conditions. The structure of the report is as follows: Section 1 outlines fundamental aspects of EMC and EMI applicable to the electric driven vehicles. Section 2 gives a background of the current automotive EMC regulatory procedures and provides information about the maximum allowed limits. Description of the EMC test facility and the instrumentation used during the measurements is provided on Section 3. Section 4 presents the results of the EMC tests in accordance with the standards, complemented by exploratory test methods, while Section 5 concludes on the main findings of the EMC measurement activity of the prototype vehicle.

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 science for policy report discusses and analyses the electromagnetic compatibility (EMC) performance of three High-Power-Charging (HPC) columns at their standby based on IEC 61851-21-2 standard. All laboratory setups and results of the tests that are presented on this work were carried out inside VeLA 9 validated EMC semi-anechoic chamber (SAC) at the Joint Research Centre of the European Commission. The results of more than 150 different measured setups on radiated emissions, conducted emissions and radiated immunity are presented and discussed thoroughly. The applicable test methodologies and instrumentation used for the measurements are fully described. EMC troubleshooting techniques were also successfully carried out for some setups, while novel exploratory work, beyond IEC 61851-21-2 was also conducted. The findings and test data on this study can be a reference material to EMC engineers and contribute to the future policy making of the relevant EMC standards.
