Register for David Theuerkauf’s September 20 seminar

The ECS Detroit Section invites you to an in-person seminar with David Theuerkauf, Technical Sales Specialist, AVL North America, at 1800h on September 20, 2023, at Mercedes-Benz R&D North America.


In constructed lithium ion batteries, only voltage, current, and temperature can be measured. This leads to difficulty making in situ analysis of electrochemical properties. Measuring and sourcing current at a high level of quality, 0.005% of full scale range, is considered ultra-high precision coulometry. Analysis of ultra-high precision coulometry metrics can be made by running cells at a slow 16-hour charge and discharge rate, with stable environmental control. These metrics can be used to compare degradation rates and anticipated rollover failure, quickly compare different potential chemistries or electrolytes, or detect lithium plating.

Student posters

Students are encouraged to present posters. Up to three posters will be presented at this event. The first three students to contact the event organizers via about presenting their work receive $100 and one year of free access to Detroit Section events.

David Theuerkauf

David Theuerkauf is Technical Sales Specialist at AVL North America. He graduated from the University of Prince Edward Island in 2020 with a BS in Design Engineering and a focus area of renewable energy. Theuerkauf worked with Dr. Andrew Swingler there on strategic overcharging of lead-acid batteries for desulfation and then completed an MS in 2022 with Dr. Lukas Swan at Dalhousie University. There he focused on cell level Li-ion testing and applications. With support from a Mitacs grant, Theuerkauf worked with Jaza Energy Hubs on solar batteries distributed in Sub-Saharan Africa. His thesis was on applications and modeling of voltage relaxation for state of charge and state of health estimation.
