Marelli Enhances Battery Management Systems with EIS Technology

Marelli Introduces Advanced Battery Management Systems

At a recent symposium, Marelli highlighted a groundbreaking approach to Battery Management Systems (BMS) for electric vehicles. This innovative solution is built on the principles of Electrochemical Impedance Spectroscopy, a technology that promises to revolutionize the way battery cells are managed. The implementation of such systems ensures batteries operate efficiently, maintaining optimal performance throughout their lifecycle.

Understanding Battery Management Systems

The primary function of a battery management system is to supervise the condition of the battery cells within a pack. By monitoring voltage, current, and temperature, the BMS guarantees that the cells operate within safe parameters. One of the significant challenges faced with lithium-ion batteries is degradation, which affects performance and longevity. Marelli's application of Electrochemical Impedance Spectroscopy (EIS) sheds light on degradation patterns, enabling precise assessments of a battery's remaining useful life (RUL).

Revolutionizing the BMS Capabilities

Marelli's existing platform known as "Marelli Energy" has already made notable advancements in measuring impedance across lower frequency ranges. Looking ahead, the next-generation BMS, dubbed "Full EIS," is intended to debut in the near future. The forthcoming release is poised to enhance the capabilities of battery management by allowing higher frequency measurements, providing a clearer picture of each cell's health. This leap forward in technology is vital for maintaining the efficiency and safety of electric vehicles.

Cloud Tracking and AI Integration

In addition to these advancements, Marelli is integrating sophisticated cloud tracking and AI applications into its BMS. These enhancements will facilitate accurate calculations of the State of Charge (SoC) and State of Power (SoP) in real-time. Consequently, the evaluation of battery health becomes not only precise but also predictive, allowing for proactive measures to extend battery life and improve vehicle performance.

Insights from Industry Leaders

Giovanni Mastrangelo, the Chief Technology Officer for Marelli's Propulsion Solutions division, remarked, "Marelli stands at the forefront of innovation in BMS technology, dedicated to addressing our clients' needs while advancing technological excellence. The integration of EIS and AI is set to significantly augment battery management safety and performance standards in the electric vehicle sector." This forward-thinking attitude showcases Marelli’s commitment to pioneering advancements in mobility technology.
