• Overview of Energy Storage with a Focus on Extreme Fast Charging and Behind the Meter Storage, Matthew Keyser, National Renewable Energy Laboratory (NREL) 

Abstract: An energy storage overview will detail the strengths and weaknesses of today’s lithium-ion chemistries.  The overview will include DOE’s future vision with regards to increasing the energy density of lithium ion systems by exploring lithium sulfur cathodes, lithium metal and silicon anodes, and high voltage liquid and solid-state electrolytes.  NREL will then introduce the DOE extreme fast charging program describing how the cell and module design needs to be improved to meet the lifetime expectations of the consumer. Furthermore, we will highlight the thermal limiting conditions associated with extreme fast charging while outlining where the heat is generated in a cell, the efficiencies of power and energy cells, and what type of battery thermal management solutions are available in today’s market. Finally, we will broadly outline DOE’s Behind the Meter Storage Program that considers BTMS electrochemical solutions for applications with less focus on energy density in mass and volume, in contrast to the extreme fast charging program, while instead pursuing potential novel battery solutions such as advanced lead acid, sodium-ion and zinc air battery systems.  In the end, we hope to show that energy storage systems are varied, and each application requires a unique solution to address today’s technological barriers.

Presenter:  Matthew Keyser joined NREL in 1992 and today manages the electrochemical energy storage group in the Center for Integrated Mobility Sciences. This group conducts modeling, simulation, and systems evaluation activities to assess and optimize energy storage components at the materials, cell, pack, and systems levels.  During his decades-long tenure at the lab, his research has focused on various aspects of advanced vehicle technologies and systems. He developed an assortment of finite element thermal and structural models for hybrid electric vehicle components. He also fostered the growth of NREL’s energy storage research equipment and facilities, which now span more than 9,000 square feet of laboratory space and enable electrochemical material fabrication, safety analysis and characterization, and world-class thermal characterization.  While at NREL, he played a key role in the invention of NREL’s R&D 100 Award-winning Isothermal Battery Calorimeters, which make it possible to accurately measure heat generated by electric-drive vehicle batteries, analyze the effects of temperature on battery systems, and pinpoint ways to manage temperatures to optimize performance and lifespan.

• Autonomous Vehicle Challenge, Electrifying the High School Student Pipeline, Dr. Marc Herniter, Rose-Hulman Institute of Technology, Dr. Thomas Foulkes, University of Illinois

Abstract: Over the past 5 years, the High School Autonomous Vehicle Challenge has introduced over 500 students to autonomous vehicles, real time programming, feedback control, and microcontrollers using a battery powered 1/18 th scale car. We have developed a model where the project can be easily integrated into the curriculum by teachers in several different forms, such as after school projects, robotics classes, or independent studies. A manual has been developed that allows students and teachers to learn independently. Although it was originally intended to be a local Indiana competition, schools from Texas, Illinois, Tennessee, New York, and Pennsylvania have participated.

The competition has been successful at introducing non-trivial engineering concepts to high school students and reinforces and shows applications of high school math and physics. Further, it allows students to work on a contemporary problem that has not yet been solved. One day they could be part of the solution, should they choose to enter the field. We would like to extend the scope of the competition to further introduce students to power electronics concepts such as battery chargers, energy storage, alternative energy, and inductive charging.

• Functional Safety Standards and Implications for Vehicle Power Electronics Design (ISO 262262), Andrew Ellenson, John Deere 

Abstract: In today’s vehicle marketplaces, both on- and off-highway, electronic control systems have become increasingly prevalent; taking the place of traditional mechanical systems.  These electronic systems perform many critical vehicle functions, including steering, propulsion, braking, and safety systems.  In many modern vehicles these functions are often accomplished through the use of power electronics components; inverters, converters, and electric machines.  While they may offer increased performance and efficiency, electronic systems often have very different and more complex failure modes when compared to their mechanical counterparts.  This shift in vehicle design has brought about the development of several Functional Safety standards over the last several years. Their aim is to help engineers identify and reduce unreasonable risk in their designs.  This presentation will look at several Functional Safety standards that affect vehicle design practices across multiple markets including HEV and BEV design.  Particular focus will be placed on ISO 26262, as it is the most comprehensive Functional Safety standard today and has a wide variety of on-highway applications from motorcycles to heavy trucks and buses.  An overview of ISO 26262 will be presented, including what is (and is not) included in the scope of the standard and how it affects the very core of vehicle electronic systems design. Examples of how these standards can affect power electronics system design will be presented.  In addition, the rise of connectivity and autonomy in vehicle designs has highlighted the need for state-of-the-art design regarding Cybersecurity and Safety of the Intended Functionality (SOTIF).  With this in mind; considerations for new standards currently being developed around Cybersecurity and SOTIF and their relationship to ISO 26262 will also be discussed. 

This talk will provide some practical introductory coverage of the topic as presented by an experienced practitioner in vehicle electronics design.  It is intended for a broad range of audience, with no previous exposure to functional safety required.

Presenter: Andrew Ellenson received his B.S. in Electrical Engineering from North Dakota State University in 2009 and his MBA from the University of Mary in 2016.  Andrew has been with John Deere Electronic Solutions (JDES) for over 16 years and is currently a Lead Electronic Design Engineer and a certified Functional Safety Engineer in their electronic design department.  His main area of focus has been in the design and testing of 700V power electronics for on-highway, agricultural, and construction vehicle traction drive systems.  For the past 2 years, Andrew has been the lead Hardware Functional Safety Engineer for JDES where he has led the development of Functional Safety processes and oversees the hardware development on Functional Safety related programs.

• Aircraft Power Electronics Trends, Obstacles and Opportunities, Dr. Timothy C. O’Connell, P.C. Krause & Associates
