|Registration and breakfast|
|9:00 - 9:20 a.m.||Welcome keynote||Samuel Wong, general manager of TI’s Battery Management Solutions business, will welcome attendees and give an overview of the latest BMS trends and open the seminar.||Sam Wong|
|9:20 - 10:15 a.m.||Guest keynote: Utility-scale energy storage and challenge on power electronics||As the world gets more electrified, energy storage is becoming a crucial enabler for numerous applications, such as mobile electronic devices and EVs. This presentation will examine various energy storage technologies driven by a diverse range of fast-growing applications, such as renewable energy, data centers, and microgrids. A special focus is given to utility-scale energy storage options, along with their challenges on power electronics technologies, to enable the grid of the future and a broader electrified green infrastructure.||Richard Zhang, Professor at the Center for Power Electronics Systems (CPES) at Virginia Tech|
|10:30 - 11:15 a.m.||Battery cost savings for variable load applications||Robotic vacuums, drones, electric lawn mowers and other self-propelled devices require their exact remaining run time in order to be able to return to their charging port. Predicting run time is complicated, however, by highly variable load patterns that can cover a wide power-consumption range. It’s important to account for peak current, not only to calculate total energy consumption but also to detect discharge termination, which can cause significant voltage drops. Basic gauging methods are highly inaccurate under such conditions, forcing designers to leave as much as 30% of capacity in reserve on arrival to recharge, which goes unused. A gauging method that correctly models usage patterns makes it possible to save 30% of battery costs. This presentation covers the main principles of this gauging method using a case study of a vacuum robot.||Yevgen Barsukov|
|11:15 a.m. - 12:00 p.m.||Introduction to student-led Formula SAE electric competition||The University of Texas Formula SAE (Society of Automotive Engineers) will showcase their electrified race car and highlight how they custom built it to meet FSAE competition requirements to take it out on race day. The UT team will review their car’s BMS specifications and the challenges encountered to get it fully operational and compliant.
