November 2019 Meeting of the Technical Society of Knoxville

November 4: John Halliwell will  speak about electric vehicles with focus on the charging infrastructure.  “Where Are We On The Road To An Electric Transportation Future”
John Halliwell is team member in the Electric Transportation Group of EPRI where his focus is smart charging and infrastructure development for plug-in electric vehicles. He joined EPRI in 2007 and has been active in the electric transportation space since 2008. John is the current chair of the SAE J1772 Electric Vehicle Conductive Charge Coupler Task Force and the SAE AE-7D Aircraft Energy Storage and Charging Committee. He has broad experience in design and application of electronic circuits and electronic systems.

Mr. Halliwell received Bachelor of Science and Master of Science Degrees in electrical engineering from the University of Tennessee, Knoxville.

I, Bob Scott, Technical Society secretary, have a 2014 Ford Fusion Energi with a 5 kilowatt hour rechargeable battery. It will go about 20 miles on a charge with the power from KUB costing about 50 cents. The car is a hybrid and it gets almost 50 miles per gallon of gasoline after the rechargeable battery is depleted. My charger is plugged into a 110 volt circuit and it takes about 5 hours to charge the battery. I could get a 220 volt charger and cut the charging time in half but Ford charges about $800 for a 220 volt charger.

You may wonder why you don’t see cars plugged into charging stations- like at Cracker Barrel. In Tennessee I might pay 6 cents per minute for the time I am hooked to the charging station and it might take two hours – or $7.20- for a 5 kilowatt hour charge that would get me about 20 miles- which is less than I get with a half a gallon of gasoline. In other states they charge for the power and not the hookup time. Improved- or radically different- electric vehicle charging regulations, infrastructure and technology can make a big difference in moving our society to mostly electric vehicles.

And maybe we can do something about it. Come to our meeting and find out.

Future Technical Society programs:

December 9: Jack Dongarra, Prof., Min H. Kao Department of Electrical Engineering, UT: The fastest computers.
