IEEE (PI)2 Austin had a busy month to successful close out our schedule for 2019! See highlights below – and keep an eye out for our next Technical Meeting, the third Tuesday in January 2020!
October 29th Technical Meeting: Electric and Hybrid-Electric Vehicles – Similarities, Differences and Developments
Dr. Mark Ehsani, Faculty, Texas A&M Universit
Dr. Ehsani covered the following groundwork regarding EVs/HEVs: An overview of EV/HEV Power Train, vehicle performance and dynamics, available and potentially available energy and power sources for vehicle application, energy conversion (energy converters), characteristics of ICE powered vehicles and battery powered electric vehicles, regenerative braking, and examples of electric and hybrid drive train technologies being developed in my group at Texas A&M University.
A lively discussion developed when Dr. Eshani concluded that:
Three fundamental problems must be solved if all-electric cars are to become widely used in the United States:
- 1- energy density,
- 2- cost,
- 3- recharge time.
–> The energy density problem comes from the fact that electric batteries can store only about 1% of the energy per pound that gasoline can. However, electric motors are about 4 times more efficiently than the internal combustion engine used in gasoline vehicles.
–> Therefore, the equivalent energy density for batteries is about 4% that of gasoline. This means you need a lot of batteries, unless your driving range is very short.
–> Until these three key problems are resolved, EVs/HEVs will continue to be a small player in the automotive world, relegated to those who can afford the costs and operating limitations.
About the Speaker:
Dr. Ehsani is the Robert M. Kennedy Professor of Electrical Engineering at Texas A&M University. He is the co-author of more than 400 technical papers, 19 books, an IEEE standards book, and 30 US and EU granted patents and patent disclosures. He has won several prize paper awards and other awards in IEEE, including IEEE-VTS Avant Garde Award for his contributions to the hybrid electric vehicle technology and IEEE field award in Undergraduate teaching in 2003.
Dr. Ehsani has led several international conferences and has served on the governing bodies of IEEE Power Electronics Society, Industry Applications Society, and Vehicular Technology Society. He is a Life Fellow of IEEE, a Fellow of SAE, a Distinguished Speaker of several IEEE societies and a registered Professional engineer in the state of Texas.
Highlights of the October 22 & 23 NEC Workshop: 2020 Updates
This two-day workshop took a deep dive into NEC 2020 National Electrical Code changes. The NEC changes were reviewed focusing on major areas of the power distribution systems which are affected by the latest changes and not on the typical Article by Article, Section by Section methods. Attendees worked through examples to understand how these NEC changes will change how power distribution systems are engineered. This Workshop was valuable for for Electrical Designers, Estimators, and Field Engineers, was also an excellent a review supplement for those preparing to take the Electrical P. E. exam. Industry manufacturers and suppliers provided exhibits and information as well.
Attendees received a PDH certificate for sixteen hours.
Extras included breakfast tacos, breakfast beverages, break refreshments, and a spiral bound copy of the 2020 NEC, plus drawing prizes which included an AEMC model 6416 clamp-on Ground Test Meter.
Instructor: Mr. Thomas A. Domitrovich is an Electrical Engineer within Eaton Corporation’s electrical group with experience in engineering, sales & marketing, business development and product management. Domitrovich is actively involved with various electrical industry organizations and most recently has focused on the continued growth of electrical safety. Mr. Domitrovich is an author with a wide range of trade magazine articles including columns in two industry trade magazines focused on electrical safety. He sits on NFPA Code Making Panel 2 for the continued development of the National Electrical Code (NFPA 70). He is also on the NFPA committee for the continued development of NFPA 73 and chairs various committees for other electrical industry organizations. Mr. Domitrovich is a LEED® Accredited Professional, a licensed Professional Engineer and holds a Bachelor of Electrical Engineering from Gannon University.
