| 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 | Download |
| 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 | Download |
| Battery charger overview – from the fundamental to the system challenges and | 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 | Download |
| 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 | Download |
| 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 | Download |
| 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 | Dominik Hartl |
| 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 | Tiger Zhou |
| 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 | Wyatt Keller |
| Systems consideration for monitors for high cell count industrial applications | When designing for high-cell count applications, determine the best system architecture can be time-consuming. This presentation will examine the pros and cons between basic system configuration options, including gauges, monitors and primary or secondary protectors while offering examples for different battery types. | Andria McIntyre | Jeff Falin |
| USB Type-C® PD3.1 extended power range, and the benefits of Type-C + BQ solution | This presentation targets introducing customers to USB Type-C PD and the new PD3.1 EPR PD spec which allows for up to 240 W to be supplied on a USB Type-C port. As more portable devices begin to transition to being powered via a USB Type-C port, and with the power range being raised from 100 W to 240 W, an all-inclusive USB Type-C PD + battery charger solution can be very valuable. | Adam McGaffin and Deric Waters | Jackson |
| Stacking systems for UPS/BBU/ESS applications | Many energy storage systems need for stacking AFE systems to acheive high cell counts battery packs. This presentation contains details on the stacking and non-stacking systems using Texas Instruments AFEs. We will look into the design considerations, system trade-off and how our devices can solve customers' challenging problems. | Terry Sculley | |
| Designing high cell count automotive applications with BQ79616-Q1 | The BQ79616-Q1 automotive battery monitor provides state-of-the-art technology in terms of feature-set, performance and BOM cost for designers working with various battery architectures and module sizes. This presentation will dig deeper into the design considerations for the application circuits needed to ensure proper functionality and performance in harsh automotive environments. | Taylor Vogt | |
| Optimizing monitor usage with multiple parallel FETs for high power applications | Lithium ion battery packs commonly use MOSFETs to prevent battery charge and discharge when conditions are outside a normal operating range. Design engineers have | Luis Hernandez Salomon | |
| TI gauges for rarely discharged applications | Rarely discharged applications can be difficult for gauges that rely on learning how a cell ages. This session shows how to design a rarely discharged system so that TI gauges can be used without impacting gauging accuracy too much. | Dominik Hartl | |
| The next generation: Wireless BMS using the CC2662R-Q1 | The SimpleLink™ CC2662R-Q1 automotive 2.4-GHz wireless MCU is optimized for the low-power TI Wireless BMS protocol. The TI WMBS protocol is a robust, scalable, low-latency high throughput wireless protocol that enables engineers to reduce the system cost and weight while still enabling a path for system-level functional safety communication layers up to ASIL-D. This presentation will introduce the concept of Wireless BMS and dive deeper into the advantages it brings for BMS design as well a high level overview of the wireless protocol itself. | Evan Wakefield |
