| 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 |
| 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 |
| 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. The 2023 Formula SAE competition season will see two competitions hosted in North America. SAE International is excited to announce for the first time since its inception in 2013, the Formula SAE Electric Class will operate as a stand-alone competition and feature over 120 universities. | University of Texas FSAE team |
| Gauge fundamentals – beginners | Are you a battery engineer new to gauge concepts? Do you want to learn how gauges work? The humble battery cell is a complex dynamic electrochemical component that requires advanced algorithms to determine the remaining capacity available at any given time for the specific conditions present in your system. Join this session if you are a new engineer working with gauges, or if you are looking for a refresher on gauge fundamentals. | Wyatt Keller |
| Going a step beyond the hardware to make the most out of low-power chargers | With everyday devices becoming smarter and having more functionality, it’s only right that chargers (even low-power chargers) will follow suit. Engineers can adapt to varying use cases without compromising their systems through software or a simple bill-of-materials change. This presentation takes a deep look into low-power design considerations, and how to make the most out of your charger. | Anthony Pham |
| Gauge fundamentals – advanced | Have you mastered gauge fundamentals and are ready to get deeper into the concepts? This module will explain in detail how different TI gauging algorithms work based on battery cell characteristics. We will also cover the pros and cons between each of these algorithms, and how you can get to market faster. | Dominik Hartl |
| Charger fundamentals – battery charging troubleshooting, tips and tricks | Battery chargers are an excellent solution for portable devices with small batteries. They are highly integrated devices that incorporate many components and features to enhance the user experience, with protections to keep users safe. Isolating and resolving problems can sometimes be difficult and time-consuming. This presentation discusses common real-world problems and solutions and offers a troubleshooting checklist to help expedite your charger development. | Bill Johns |
| How will the new European Parliament regulations affect your battery design? | In March 2022, the European Parliament passed bill 2020/0353/COD, now COM(2020)798 regulation of the European Parliament and of the Council concerning batteries and waste batteries. This presentation highlights how this regulation affects battery management system architectures, such as the requirement for removable or replaceable battery packs, battery authentication, and labeling requirements specific to those battery packs. TI battery gauges can help you comply with these requirements, to open or service the European market for your device. | Kipp Hayes |
| Advanced charger features for single cell applications | With advancements in portable applications, requirements continue to expand in the areas of wide input voltage, high power density and long run times. This presentation discusses these requirements, and how TI charger features such as increased power density and charge efficiency, low quiescent current, flexible temperature profiles, reduced electromagnetic interference, and a wide input voltage enable the best user experience. | Khalid Bairuti |

| How does gauge accuracy affect battery pack longevity? | With batteries becoming the primary energy storage and power supply in many applications, their efficient use and run time, performance and longevity are important aspects. A field gauge can not only report battery operational status such as voltage, current and temperature, but can also perform safety diagnostics and protection. The measured conditions of battery cells are then used to calculate state of charge to ensure the safe charge and discharge of the battery. New innovations in hardware, combined with TI’s Impedance Track™ algorithm, enable high-accuracy gauging under different conditions. This presentation covers the hardware and algorithm features that help you prolong battery life and get the most out of your battery system designs. | Summer Huang |

Applications with a high cell count need appropriate considerations when implementing balancing techniques for optimal life cycles. This presentation covers cell-balancing fundamentals, different solution types, design challenges, and real application examples for automotive and industrial systems. | Luis Hernandez Salomon |
| Battery gauging technology for lithium-iron-phosphate battery chemistries | Lithium-iron-phosphate (LiFeP04) battery chemistries are becoming more popular in automotive and industrial applications because of their low material cost, long lifetimes and excellent temperature stability. These benefits are offset, however, by properties that complicate the accurate determination of state of charge, such as very low variation in open-circuit voltages. This presentation discusses techniques to optimize the accuracy of gauging results for LiFeP04 chemistries using TI’s Impedance Track™ technology. | Charles Sestok and Chen Li |
