Design of a Battery Pack for the Power System of an All-Electric Aircraft by Cell Characterization

The battery characterization and modelling of a Lithium-ion battery aimed at supporting the design of the energy storage system of an All-Electric Aircraft (AEA) is presented. Specifically, the developed model is employed to evaluate the energy and power performance of a battery pack designed for the AEA concept X- 57 Maxwell Mod.II. The preliminary battery pack sizing is performed referring to a project-flight mission-oriented to air city taxing. The evaluation of the design targets satisfaction has been verified through a simulation study based on the proposed battery modelling. The comparison between the simulation and preliminary results confirms the need of employing a battery dynamic model for designing AEA's battery pack that satisfies all targets imposed.
