EV fast charger lead battery back-up: challenges and opportunities

Agenda for
5-9 September

Don Karner
President, Electric Applications Incorporated
With the accelerating production of electric vehicles as a means of carbon reduction, a rush to develop a comprehensive charging infrastructure is underway. With a focus on vehicle fast charging at powers of 350 kW to 600 kW, battery energy storage is required to minimize the grid power demand. Lead batteries provide an excellent solution for this application. However, the design and certification requirements for this application are both new and still evolving. This presentation provides an overview of the operational and safety challenges for lead batteries in EV fast charge demand reduction duty. Typical duty cycles and performance requirements will be discussed along with safety certification and test requirements for the North American market.


Donald Karner is President of Electric Applications Incorporated (EAI), located in Phoenix, Arizona and supporting energy storage applications and development. Prior to this, Mr. Karner founded and served as President of Electric Transportation Engineering Corporation (ETEC), specializing in fast charge infrastructure solutions for on road and off-road electric vehicle applications and development and testing of alternative fuel vehicles.

In addition to his experience at ETEC and EAI, Mr. Karner has fifteen years of experience in the electric utility industry where he served as Executive Vice President and Chief Nuclear Officer for construction and operation of the 4,100 megawatt Palo Verde Nuclear Generating Station.

Mr. Karner holds a Bachelor of Science degree in Electrical Engineering from Arizona State University and a Master of Science degree in Nuclear Engineering from the University of Arizona. He is also a graduate of the Public Utility Executive Program of the University of Michigan.
