A Tool for Vehicle Electrical Storage System Sizing and Modelling for System Simulation

Abstract

A tool for battery system virtual prototyping based on an empirical model and a database has been developed. Battery cell characteristics are gathered and correlated with specific scaling laws, then used to build a battery pack meeting a set of target requirements. The corresponding pack model is then created to be used in a system simulation platform to evaluate the vehicle behavior with prototyped virtual battery pack. The methodology has been applied and validated in two test cases: Li-ion cell sizing and EV pack sizing.
