Automatic Parametrisation Procedure for Equivalent Circuit Models of Li-ion batteries

​​​The main aim of Vicentiu's research conducted in this project is to develop an effective system parametrisation process targeting Li-ion battery models and having as a prime example the Equivalent Circuit Model structure referred to as MoBat and proposed by the industrial sponsor of the project, AVL. The first segment of the project targets an automatic extraction process of information from random measurements (test bed, drive cycle) leading to model parameter values and encompasses a predefined set of instructions iteratively improving the result of the parametrisation and quantifying the accuracy of the model.

A second research element uses an evaluation of the accuracy of a prior model of the battery to devise data-effective acquisition strategies aiming to reduce system testing efforts while capturing enough information to improve the parametrisation and validate the model following a specification or targeted application defined by the user. In addition to the research conducted using MoBat, the project will also consider the parametrisation of similar models proposed for the virtualisation of the same or different systems, targeting the reconfiguration and transfer of the instructions part of the parametrisation procedure. Finally, the dissemination of project results is set to be achieved by the PhD thesis, while the impact of the research will be amplified through close collaboration with the development team integrating the results of the project into commercial software - ModelFactory
