Title of speech: 

The price of degradation — The value of prognostics – Opportunities and Needs in Battery Health Estimation

Abstract of speech: 

Replacing a gasoline or diesel internal combustion engine vehicle (ICEV) with an electric vehicle (EV) will zero out the direct (tailpipe) GHG emissions and depending on where it charges can have 75% lower GHG emissions. Key barriers to EV adoption include the higher first cost of EVs compared to ICEVs and the up-front investment needed to provide charging infrastructure. The total cost of ownership and the cost of the fleet transition depends on the lower operating cost due to fuel and maintenance savings that depend on the route, utilization, and charging of the vehicle. Behind the meter, vehicle to grid and 2nd life applications can provide additional cost benefits if the battery stays healthy.

The battery state of health (SOH) is currently estimated by determining capacity (cyclable energy) and cell resistance (power capability). Unfortunately, estimating these parameters with high confidence can only be done under certain discharge patterns. Identifying the physical origin of the degradation is even more difficult but very important, because it can inform the Battery Management System (BMS) about electrode specific constraints and hence prevent further degradation. Power electronics can help identify the intrinsic “aging wrinkles” in the battery material as it ages.

Title of speech: NASA Aeronautics Strategies for Hybrid/Electric Propulsion and Transforming Aviation

Abstract of speech: 

NASA is making significant progress towards establishing the viability of Electrified Aircraft Propulsion (EAP) through a combination of aircraft conceptual design studies and advancement of key tall-pole technologies.  Partially turboelectric and parallel hybrid candidates have been shown viable for introduction into service in the mid-2030s, and a long-term vision has been established for a fully turboelectric system.  NASA is developing key powertrain technologies that are applicable for a wide variety of aircraft configurations, including electrical machines (motors/generators), converters (inverters/rectifiers), and the underlying electrical materials for EMI filters and cabling.

In the next 5 years the goal is to narrow the focus to the most viable concepts as a means to prepare for flight demonstrations of those concepts. An electric aircraft power system test facility (NASA Electric Aircraft Testbed (NEAT)) has reached operational status at and is being used to perform both industry partnership testing and in-house NASA R&D. It is believed that the correct building blocks are in place to test a viable large-plane EAP configuration in the not too distant future.

This presentation will address the strategy behind NASA’s research and development efforts to accelerate this market. It will cover the enduring electrified propulsion research needs including the development of system concepts, electric machines, converters,  innovative materials, components, tools, and methods that enable the performance, reliability and durability of these systems.

System Operations -Defenders of the Grid- Past, Present, Future

Abstract of speech:

The electric grid is vital to the customers it serves. Many events have proven the belief that the electric grid is the most critical of the critical infrastructures in the world. It has been described as the most complex machine man has ever made. Research links prosperity and education to the availability of a reliable and secure electric grid. The product (electrons) traveling at close to the speed of light and consumed almost as quick as it is generated with no scalable ability to store it (at least not yet). While the grid has undergone changes for over the past hundred years, the changes we have seen recently and expect over the next several decades accelerate that pace of change to say the least.  As a wise industry leader once told me, we are trying to re-wire our house while still living in it. Any of us who have remodeled a home while still living in It know how challenging, frustrating, and difficult this proposition is.

We are facing fundamental changes in the electric gird we have benefited from for over a century. From the decarbonization of generation, development of micro-grids, potential of new nuclear technologies, development of solar and wind resources, emerging energy storage technology, and more intelligent customer technology, the grid is undergoing and will undergo real change in coming years. But in spite of that change, or perhaps because of that change, the role of the System Operator becomes more important than ever. Throughout the history of interconnected system operations, the System Operator – the Defender of the Grid – has always been there to act on behalf of the users of the electric grid – our customers and communities. So how do we bridge between what we have now, what we will have in 5 years, and what we will have 20 years from now. At the end of the day, our customers expect for the lights (or whatever lights turn into 50 years from now) to stay on. That metaphor – keeping the lights on 24X7X365, continues to be the mission of the System Operator. It should be a wild and rewarding ride.
