Marelli Introduces Advanced Battery Management System at CTI Symposium 2024 in Berlin

Marelli's Breakthrough in Battery Management Systems

At the prestigious CTI Symposium held in Berlin on December 3, 2024, Marelli introduced a groundbreaking advancement in Battery Management Systems (BMS) aimed at revolutionizing automotive technology. This new system, which leverages Electrochemical Impedance Spectroscopy (EIS), promises to enhance the management of battery cells significantly, ensuring their optimal operation and exceptional performance.

Understanding the Importance of BMS

Battery Management Systems are critical electronic control units that oversee the performance and safety of battery packs. They monitor various parameters, including voltage, current, and temperature, to maintain safe operational limits. As lithium-ion batteries degrade over time—leading to reduced capacity and increased resistance—effective management becomes essential in determining their remaining useful life and economic value. Marelli’s recent innovations in BMS technology intend to address these challenges efficiently.

Traditionally, EIS has been a tool primarily used in laboratory settings, often seen as an expensive measurement technique. However, Marelli has developed a cost-effective application of EIS ready for mass production. This breakthrough not only enables early detection of anomalies but also operates to prevent serious issues, such as thermal runaway, thereby significantly enhancing battery safety.
