Second Life for Li-Ion Automotive Batteries
A strategic issue in circular economy consists in supporting new technologies, products and services related to Second Life Batteries, consisting in re-using end-of-life automotive Battery Energy Storage Systems (BESSs) in stationary applications. A key aspect for ensuring an effective reemployment of aged BESS will be the development of accurate and flexible models of electrochemical cells. Indeed, the availability of these models will be useful for performing accurate determination of the actual State of Health (SoH) of the cells, as well as accurate estimation of their State of Charge (SoC). Therefore, this project aims at developing suitable models of electrochemical cells characterized by a very flexible and accurate system identification procedure. During the project, the model will be used for performing SoC and SoH estimations, together with optimal balancing of the BESS. Moreover, it is expected to develop a Battery Management System prototype for evaluating the performances of the developed algorithms in a realistic experimental setup.
