This paper describes research into the definition of experimental protocols, and the development of a numerical model of a battery, associated with a parameterization assistant tool in order to follow battery ageing. This work was carried out as part of the SIMSTOCK program. The experimental characterizations (ageing cycle tests and characterization protocols) are defined in association with the different research lab partners of the project. They were performed on Lithium-ion VL6P cells supplied by Johnson Control - SAFT (J.C.S). The characterization protocols are performed at different phases of a program: initially to establish the reference value parameters and periodically, in order to follow all the changes occurring during the ageing of a Li-Ion battery. The different numerical tools presented in this paper are adapted to the LMS-Imagine Lab AMESim simulation platform. The present model makes it possible to simulate the dynamical voltage response of the battery as a function of inlet current and temperature. The identification tool associated is able to determine from a temporal experimental characterization of the battery (U and I), the data necessary for the implementation of the parameters in the model. The assistant tool identifies the parameters of the numerical model at different ages of the Li-Ion battery. Its results are used in order to quantify the influence of ageing phenomena on the performance of the battery considered.
