Abstract

ABSTRACT: Sizing a storage system plays an indispensable role in providing a constant energy source. However, these systems struggle with the instability of resistive parameters between cell and cell, which finally manages to vary the design forecast. This work contributes with a modeling and simulation methodology for an EV power system using the Matlab-Simulink platform. The aim is to estimate the state of charge and, therefore, the autonomy of the electrical traction system. Both internal and external conditions in which an EV works are studied and an EV prototype is built to validate the results of the simulations. The computational model proposes the use of characteristic polynomials of the work curves of an electric motor and of the RC components of the equivalent circuit of battery. The mathematical equations that represent the forces to which the traction train is subjected are modeled and the current that is extracted from the storage system (????????).
