9:15 a.m. Guest keynote: EV and its battery control system
The automotive market is undergoing a seismic industry transformation, largely driven by lithium-ion batteries and the ascendance of electric vehicles. To provide customers with a compelling driving experience they've grown used to with internal combustion engine vehicles, e-propulsion systems need to be architected to provide more power and greater efficiency. Serving as a brain of the e-propulsion system, battery management systems are adapting to be safer and more intelligent while provide greater performance and lifetime management.
Dr. Tao Wang, vice president, Visteon 
10:00 a.m. Battery technology update This presentation gives an overview of new battery technology development during last few years. The main technology trends are diverging into pursuing higher energy cells through either capacity increase or voltage increase. Both trends have seen some break-through developments, where Si-anode batteries with higher capacity finally became available for sampling, and new high-voltage capable electrolyte results have been published which enable higher energy materials like over-lithiated (OLO) and cation-disordered oxides. At the same time battery companies are focusing on cost reduction through replacing expensive Co with cheaper and more price-consistent Ni, Mn and Fe in cathode materials. Higher discharge rate batteries (mostly around LiFePO4, and NMC) continue growth in production quantities, driven by power tools and electric vehicles. Power backup / grid management is becoming an important area where many chemistries complete. Some extreme battery life (million miles EV) has been demonstrated with single crystal NMC. Finally, futuristic technologies such as Li-air and Li-Sulphur battery are reviewed as well. Yevgen Barsukov
11:00 a.m. Charging trends in low power industrial systems Low power battery operated systems such as earbuds, smartwatches, hearing aids and medical patches are all around us and are instrumental in enabling a better and more convenient lifestyle. With many of these products in close proximity to the end consumer, battery- powered system designers have a key responsibility in ensuring the products they design are safe, reliable and provide a rich user experience.  In this presentation we will go over some of the new charging trends in low power systems and how to build a robust battery management system for your product. Arelis Guerrero
1:30 p.m. Battery charger overview – from the fundamental to the system challenges and
application solutions
This presentation explains the major differences and the technical reasons between a battery charger and a DC-DC converter. The key charger features such as power path, dynamic power management, input source detection will be introduced. The associated system challenges such as charging accuracy, power flow control, and flexible charging sources will be discussed. Different industrial application examples using different charger features will be analyzed to help the audience gain some in-depth understanding. Eric Zhao
1:30 p.m. Battery gauging fundamentals  Gauging battery state accurately is a complex challenge which requires advanced algorithms. This session explains the challenges and how TI addresses them with various gauging algorithms. Dominik Hartl
2:30 p.m.  Switching charger PCB layout tips and example PCB Layout is an important part of the switching charger design. It affects charger efficiency, thermal, regulation accuracy, ripple, EMI and even converter stability. This presentation introduces several practical tips to guide you through the layout process. It covers FET and inductor selection, components placement, ground partition, layout and size optimization. An example buck boost charger is demonstrated in the presentation. Tiger Zhou
2:30 p.m.     Using TI gauges advanced charging algorithm Several TI gauges can supply charging parameter information to a system based on various conditions.  This session discusses how to use the advanced charging algorithm feature. Wyatt Keller
3:30 p.m. Resolving battery charging common application issues To safely charge a battery pack, battery chargers have multiple internal feedback loops to control, and sensing circuits to monitor, input and output voltages and currents. The charger also monitors battery and charger die temperature.  With such complexity, battery charger issues such as collapsing the input power source, reduced or no charge current, failure to terminate charge in a timely manner or inefficient charging are not uncommon.  This presentation explores the root causes of the most common battery charger issues and not only how to resolve them but how to prevent them from occurring in the first place. Jeff Falin
3:30 p.m. Designing with TI gauges using TI's tool chain TI gauges are highly configurable for a specific battery/cell and application. To get the best performance out of TI gauges, the TI tool chain, consisting of an EVM, a PC interface and software, bqStudio, is the best tool to develop optimal configuration. Join this session to learn more about TI's tool chain and how to use it for your next design. Jackson
