The INSTABAT project – an acronym in English for an innovative physical / virtual sensor platform for battery cells – is financed by approximately four million euros from the European Commission and has the University of Aveiro as one of the participants. The initiative foresees the development of a fiber optic sensor platform for electric vehicle batteries. The project is an integral part of the Battery 2030+ roadmap, a large-scale, long-term initiative to reach the sustainable batteries of the future.
The intention of this project is to monitor, in real time and in operation, essential parameters of a lithium-ion battery cell, providing with greater precision the states of certain indicators such as load, capacity, power, energy and safety, allowing to improve performance and the so-called QRL trilogy (quality, reliability and battery life).
The project, reveals the University of Aveiro in a statement, foresees the development of a proof of concept of technologies and functionalities of intelligent sensors, integrated in a battery cell. The goal is to be able to perform operational monitoring, correlate the evolution of monitored parameters with the phenomena of physical-chemical degradation, and improve battery functional performance and safety through improved algorithms, which provide more accurate indicators in real time .
The multi-sensor platform under development will be applied to electric vehicles and aims to reduce aging, improve safety and autonomy margins, trigger self-regeneration and facilitate the use as a second battery life.
The University of Aveiro team that participates in this program has the researchers Micael Nascimento, Carlos Marques, João de Lemos Pinto and the project management of Luísa Sal. INSTABAT is coordinated by the Commissioner for Atomic Energy and Alternative Energy (CEA, France ) and also has the participation of other French research centers (CNRS and INSA). and business partners, such as BMW, and Infineon Technologies (Germany), Faurecia (France) and Varta (Austria).
