We are happy to announce the addition of 3 new series of eLearning courses:
The IEEE Transportation Electrification Community announces the availability of three new short courses on subjects of interest. Each short course is prepared and presented by a recognized subject matter expert. Each course consists of five modules. Each module runs approximately one hour.
The approach is thorough and includes materials beyond the minimum, in order to put the subject matter in context. The material is almost exclusively viewcharts, with the presenter’s comments on the audio. It is possible to stop at any point, and to repeat any part of the presentation. Mastery of the content should be easy for anyone who makes an appropriate effort.
Electric motors form an integral part of the modern automotive system. In addition to playing a central role in propulsion systems in modern hybrid, plugin hybrid and electric vehicles, they also play a significant part in auxiliary systems including pumps, power steering, power windows, etc. Thus, the development of compact, lightweight, high efficiency, and proper torque speed profile becomes crucial.
Selection of electric motor for traction is a very important step in the design of efficient drivetrain, where issues such as performance, efficiency, reliability and cost need to be critically evaluated. This emodule on electric machines and drives will discuss, constructional details, principles of operation, electromagnetic design and performance indices of various motors. Advantages and challenges in each motor in the context of automotive traction will be presented.
The fuel cell is a potential candidate for energy storage and conversion in our future energy mix. Indeed, a fuel cell is able to directly convert the chemical energy stored in fuel (e.g. hydrogen) into electricity, without undergoing different intermediary conversion steps. Among the different fuel cell types, the proton exchange membrane (PEM) fuel cell has shown great potential in automotive applications, due to its low operating temperature, solid-state electrolyte, and compactness. Many experts consider the PEM fuel cells to be one of the potential embarked energy candidates for terrestrial transportation.
This eLearning course will mainly focus on the proton exchange membrane (PEM) fuel cell technology which has been used specially in automotive applications. The PEM fuel cell fundamentals, such as its physics, structure, power characteristics, efficiency, will be presented and discussed. The fuel cell system with its key ancillary components, such as air compressor, hydrogen tank, power converter, will also be introduced. Different powertrain configurations with fuel cells in automotive applications will be discussed and shown with real examples around the world. An emphasis on the fuel cell economic aspects and a short introduction to hydrogen economy will be given at last.
Electric vehicles and plugin hybrid electric vehicles (PEVs) have attracted worldwide attentions because their capabilities to displace petroleum usage and improve energy and environment sustainability. One of the key constraints for the mass market penetration of PEVs is the inconvenience and safety concerns associated with charging. Wireless charging using Wireless Power Transfer (WPT) Technology, as an alternative to conductive charging or batteryswapping, can provide the convenience and safety requirements. Recently, EV battery wireless chargers have been realized at large power levels (>50kW) with reasonable sizes, distance in excess of 200 mm, DCtobattery efficiency of 96.5%, and a misalignment of up to 600 mm, using magneticresonance technology. This breakthrough will have strong impact on PEVs and a variety of other applications, including consumer electronics, home appliances, medical implant devices, and some industry applications.
This tutorial focuses on the key technical challenges of WPT, including coil design, system analysis using analytical methods, simulations of the WTP system; resonant topologies suitable for various applications, and power electronics topologies associated with WPT. The presentation will be mostly focused on high power applications in the kilowatts and tens of kilowatts range but other wireless power transfer technologies and applications of WPT, as well as environment safety, will be briefly discussed.
We will continue to offer the following elearning courses on the IEEE eLearning Library:
There is a great deal of interest in batteries today, particularly in lithium-ion batteries. This tutorial is one of five in a series developed by Robert Spotnitz, President of Battery Design, LLC.
In this first tutorial Dr. Spotnitz provides an overview of batteries, including a brief history of battery development. Interest in lithium ion batteries centers around their vehicular applications. and Dr. Spotnitz reviews the types of batteries currently used in hybrid electric vehicles (HEV), plug-in hybrids (PHEV) and vehicles fully powered by batteries (battery electric vehicles or BEV).
In a detailed discussion of batteries, he introduces the terminology, the battery market, types of batteries currently available, and the battery specification process. Finally, Dr. Spotnitz discusses Smart batteries and the various standards available for batteries.
There are four tutorials in this series developed by James Grover. Dr. James Gover, IEEE Life Fellow, is currently Professor Emeritus at Kettering University and teaches graduate courses on power semiconductors, advanced power electronics and fuel cell system integration and packaging.
This course focuses on the dynamics of electronic continuously variable transmissions and compound split systems, with examples of both, and on power variators.
It begins with a historical perspective of hybrids. The course then explains the fundamentals of the input split e-CVT and discusses the operation of transmissions of various car models. Energy storage systems and their cost are also covered.
IEEE Real World Engineering Projects (RWEP)- EV Focused Projects
The goal of the RWEP Program is to provide university educators of electrical engineering (EE), computer engineering (CE), computer science (CS), biomedical engineering (BE) and electrical engineering technology (EET) world-wide with a library of high-quality, tested, hands-on team-based society-focused projects for first-year students.
