DETROIT,
Dec. 3,
2024 /PRNewswire/ -- At the 2024 CTI Symposium
in Berlin, Marelli announces a new
pioneering advancement in Battery Management Systems (BMS) for
automotive applications, with a BMS based on the Electrochemical
Impedance Spectroscopy. This development is set to elevate the
standard for battery cell management by ensuring optimal operation
and enhanced performance of the battery pack.
The battery management system is an
electronic control unit that monitors the state of the cells
in a battery pack to ensure their safe operation
within specified voltage, current, and temperature ranges.
Degradation of lithium-ion batteries
results in capacity reduction and increased
resistance. The innovative application of
Electrochemical Impedance Spectroscopy (EIS) in battery management
systems provides insights specifically into the lithium-ion
batteries' degradation, and related capacity reduction and
increased resistance. Such insights are essential for accurately
determining the remaining useful life of the batteries and
therefore their residual economic value. Traditionally, EIS has
been an expensive laboratory tool, but Marelli has developed a
cost-effective solution ready for large-scale production, capable
of early anomaly detection, thus preventing thermal
runaway.
The current generation of "Marelli Energy"
BMS platform, known as "EIS ready", already brought significant
improvements related to its ability to measure impedance in lower
frequency ranges. Moving from that point, the development of the
next-generation "Full EIS" BMS, set for release in 2025, will
further enhance capabilities, enabling higher frequency
measurements and providing a comprehensive overview of each battery
cell's condition.
Further integrating cutting-edge cloud
tracking and AI applications to empower calculation algorithms, the
new "Marelli Energy" BMS platform optimizes real-time estimation of
the State of Charge (SoC) and State of Power (SoP) of the battery
pack, offering a precise evaluation of the battery's remaining
useful life (RUL) and degradation. These advancements bring longer
battery life, improved drivability, and extended driving
range.
Giovanni
Mastrangelo, CTO of Marelli's Propulsion Solutions business
said: "Marelli stands as a true pioneer in the field of
innovative applications and cutting-edge BMS technology
development, aiming to meet our customers' needs while presenting
them with new opportunities for technological excellence. The
adoption of EIS and AI in BMS technology is anticipated to grow
substantially in the coming years, enhancing safety, reliability,
and performance standards in battery management for electric
vehicles."
Marelli is sharing this new development and
its commitment to technological excellence at the CTI Symposium,
held in Berlin on December 3 and 4, where Davide Cavaliere, Battery Management Systems
Product Manager, is delivering his keynote speech "Electrochemical
Impedance Spectroscopy (EIS) implementation in Battery Management
Systems (BMS)". This session provides an in-depth look at the
development process, design challenges, and future enhancements of
Marelli's BMS technologies and innovative applications.
