Intelligent Battery Management System
Letting Lithium-ion batteries live smarter, longer, and more sustainable lives. ...
This year, Pietro Iurilli, who completed his PhD at CSEM in collaboration with ETH Zürich, was honored for his pioneering research on leveraging Electrochemical Impedance Spectroscopy (EIS) to model and monitor the aging of lithium-ion batteries.
The Battery Young Researcher Award is one of the most prestigious distinctions in the field of batteries, presented during the Battery Innovation Days. This flagship event brings together Europe’s top researchers, industry leaders, and policymakers.
This year, Pietro Iurilli, who completed his PhD at CSEM in collaboration with ETH Zürich, was honored for his pioneering research on leveraging Electrochemical Impedance Spectroscopy (EIS) to model and monitor the aging of lithium-ion batteries.
Battery Management Systems developed at the CSEM Battery Innovation Hub
Pietro’s PhD research, conducted at CSEM’s Battery Innovation Hub between 2018 and 2022, explored how EIS, a non-invasive technique, can detect and analyze the internal degradation mechanisms of batteries with unprecedented precision. His work has paved the way for a new generation of Battery Management Systems (BMS), featuring dynamic models capable of:
🔹Accurately simulating battery behavior, taking aging into account
🔹Identifying specific degradation mechanisms, such as lithium inventory loss or cathode active material degradation
🔹Optimizing State-of-Health (SoH) estimation algorithms
By using advanced tools like Distribution of Relaxation Times (DRT) to better interpret EIS data, Pietro demonstrated how these analyses enable the configuration of precise electrical models tied to specific physical mechanisms. Validated across a wide temperature range (-10°C to 35°C), these models deliver unmatched accuracy in predicting battery performance under real-world conditions.
The Renault Twizy prototype, equipped with a Battery Management System developed at CSEM, showcased during the CSEM Business Day 2024 alongside Andreas Hutter, Group Leader of the Battery Innovation Hub; Gaël Mourouga, Battery Software & Algorithms Developer; Leon Locher, Battery BMS Software Developer at CSEM
In collaboration with initiatives like the European NEMO project, Pietro’s work resulted in:
➡️The development of advanced models and algorithms
➡️The creation of hardware prototypes integrating EIS measurements and wireless data transmission
➡️Rigorous validation up to TRL7, demonstrating their readiness for industrial adoption
With support from the Battery Innovation Hub, Pietro Iurilli’s work exemplifies how fundamental research can be transformed into practical tools for the industry.
