Project Description
Context
According to the EU long-term vision, the Europe of the future would be a low-carbon and healthy continent, based on clean energy sources and efficient transportation, thanks to full exploitation of renewable energies, electrification, smart mobility and digitalisation. The electrochemical battery, regardless of its chemical compound, is one key technology to realise the above vision. To make the battery of the future the sustainable pillar for the development of a strategic technological asset, the battery innovation has to face challenges aiming at extending the lifetime of the battery cell and at making it safer and more economically viable
Overview of the project
This project will include the design, development, deployment, and test of a cyber-physical system supporting the concept of SMART BATTERY CELL. Accordingly, a chemical neutral architecture will be researched and proposed that is able to measure, monitor and diagnose the battery cell status, in-situ and while in-operation, through real-time online electrochemical impedance spectroscopy (EIS), distributed temperature and strain measurements. This multi-parameter approach is integrated in a model-based data-processing framework that collects data and sensor information to provide knowledge about the battery cell state-of-charge, state-of-health, and state-of-safety.
A fully integrated EIS measurement system will be designed and fabricated to allow for dedicated low-power signal processing. The thermo-mechanical sensors will be based on wafer-level vacuum packaged silicon MEMS resonators to complement the set of sensors interfaced with the battery cell.
The project partnership comprehends expertise in all needed development areas, such as VLSI design and fabrication, MEMS sensor design and fabrication, signal processing, modeling, system identification, reliability, and safety testing capabilities and facilities. The strong background of the proponents in the area of instrumentation and measurement will assure that all metrological attributes of the smart battery cell will be taken into consideration to provide instrumentation-grade performance to the realized prototypes.
