The San Francisco Bay Area chapter of the IEEE Power Electronics Society (IEEE SFBAC-PELS) is interested in the development of power electronics technology. This technology encompasses the effective use of electronic components, the application of circuit theory and design techniques, and the development of analytical tools toward efficient electronic conversion, control, and conditioning of electric power.

SFBAC PELS is the winner of three awards in 2017: PELS Best Chapter, Region 6 Outstanding Chapter, and SCV Section Outstanding Chapter.

In order to tackle and solve the prediction problem of the lifetime of Li-ion batteries, it is essential to have awareness of the current state and health of the battery pack. To be able to accurately predict the future state of any system, one must possess knowledge of its current and future operations. Using derived models of the current and future system behavior, a model-based prognostics approach can be implemented as a solution to the prediction problem.

As more and more autonomous electric vehicles progressively emerge in our daily life, a very critical challenge lies in accurate prediction of remaining useful life of the systems/subsystems. Batteries, power electronics conditioning systems, and motors are integrated to form the powertrain in electric vehicles; one of the most critical systems. In the case of electric aircrafts, computing remaining flying time is critical for safety, since an aircraft that runs out of power (battery charge) while in the air will eventually lose control leading to catastrophe.

This presentation covers a physics-based modeling approach implemented for case studies in capacitor and battery prognostics which are an integral part of an electrical powertrain system. The general approach of model-based prognostics will be examined as a potential solution for safety critical problems related to battery state of charge and state of health.

About the Speaker:

Dr. Chetan S. Kulkarni is a staff researcher with SGT. Inc, at the Prognostics Center of Excellence and the Diagnostics and Prognostics Group in the Intelligent Systems Division at NASA Ames Research Center. His current research interests are in Systems Prognostics and Health Management related to modeling and simulation of hydraulic and electromechanical actuators, aircraft electrical power systems and in the area of developing component level physics-based models for prognostics applications for electronics systems, lithium based battery technology, cryogenic fueling systems, small and cube satellites.

He graduated from Department of Electrical Engineering and Computer Science, Vanderbilt University, Nashville, TN MS ('09), PhD ('12) and BE from the University of Pune ('02). Prior joining Vanderbilt University, he was a Research Fellow at the Department of Electrical Engineering, IIT-Bombay, where his research work focused on developing low cost substation automation system monitoring, control devices and partial discharge on transformers. Earlier he was technical team member of the Power Automation group at Honeywell Automation India Ltd (HAIL) for 4 years.

Dr. Kulkarni has authored more than 60 publications including journals, conferences, book chapters along with several best papers awards. the He is a SM IEEE, SM AIAA and member of SAE and PHM Society. He is associate editor of the SAE Journal of Aerospace and IEEE Access Journal on Advances in Prognostics and System Health Management. Dr. Kulkarni also chairs Professional Development and Education Outreach subcommittee within ISTC.
