+ Abstract ▼

Conventional battery management systems face important trade-offs between efficiency, reliability, and flexibility. In conventional battery packs, cells are typically connected in series, making the overall system strongly dependent on the weakest elements. A failure in a single cell or associated component can compromise the operation of the entire battery pack. This challenge becomes even more pronounced in second-life battery applications, where cells may exhibit significant differences in state of charge, capacity, and aging. Smart battery architecture offers a new approach by integrating power electronics and distributed control capabilities at the battery-module level, allowing individual battery units to operate more independently while enabling advanced functionalities at the system level. This presentation discusses the concept and development of smart battery architectures, with a focus on advanced control functionalities. The proposed approaches enable coordinated state-of-charge balancing, pulsed-current operation, fault-tolerant operation, and safe operating modes while preserving the modularity and scalability of the battery system. By moving beyond the conventional BMS paradigm, smart batteries open new possibilities for more flexible, resilient, and multifunctional battery energy storage systems.

His main research interests include switched-capacitor and hybrid converters, high-gain DC-DC converters, single-phase rectifiers, inverter paralleling, wind energy conversion systems, wide-bandgap (WBG) semiconductors, and power electronics applications in cryogenic environments.

+ Abstract ▼

Cryogenics involves achieving and using extremely low temperatures, at which material properties can change significantly. Its integration with power electronics offers opportunities to reduce losses and increase converter power density, particularly in applications that already have cryogenic infrastructure. This plenary presentation will introduce the fundamentals of this integration and its main challenges, including the characterization of semiconductors and passive components, as well as converter design. Potential applications in electric mobility, electrified aviation, and superconducting systems will be discussed. The presentation draws on the speaker’s experience as a visiting professor at Centrale Supélec, part of Université Paris-Saclay, conducting research on cryogenic power electronics at the GeePs laboratory. As an application example, it will address the development of a power converter for a 1 MW ultrafast electric vehicle charging station.

+ Abstract ▼

This talk addresses how static and dynamic wireless charging can contribute to the future of electric mobility, as well as what is still needed for their large-scale deployment. Static charging is the most mature technology and already benefits from well-established standards. The challenge lies in design and validation, as ensuring interoperability between coils from different manufacturers requires testing across a wide range of operating conditions. The solution presented involves automating test platforms, making the validation process faster and more repeatable. Dynamic charging transfers energy while the vehicle is in motion but still lacks unified standards. Its primary design challenges are coupling between coils that vary constantly with the vehicle's position, and the need to maintain system efficiency while the vehicle moves. The solutions presented address these gaps and have been validated at full scale. This talk also addresses the prospects for this technology.
