This paper describes the steps performed in the development of a lumped model of electrochemical battery, as well as its corresponding parameter identification assistant tool and the first results obtained. The numerical model is adapted for the LMS Imagine Lab AMESim simulation platform. This model makes it possible to simulate the dynamic voltage response of the battery as a function of current and temperature. This behavioral model uses the approach of equivalent electrical circuits to simulate the physical phenomena inside the battery. Thus, the open circuit voltage, the ohmic losses, the transfer of charge, the double layer capacitance and the diffusion of species can be represented. This model can be adapted for a large number of batteries and supercapacitors, representative of the latest generation of high power energy storage systems.
