Abstract

In this paper, we present a dynamic simulator that uses a proton exchange membrane fuel cell (PEMFC). This source, is used as a primary source with a supercapacitor (SC) considered as a secondary source. This simulator integrates a PEMFC’s dynamic model, validated on the Bahia bench and a semi-empirical model of SC. The developed model is implemented using the macroscopic energetic representation tool (EMR). The energy management system (EMS) is based on rule-based power management, where a low-pass filter splits the power among sources (PEMFC and SCs) using a cut-off frequency of 0.2Hz, and a controller block that regulates the bus voltage deduced by the EMR’s inversion-based control approach.

Highlights

The world consumption of fossil fuels has been growing continuously for more than half a century
The evaluation of the developed hybrid simulator performances, was conducted under the power profile calculated from the new European driving cycle (NEDC) ECE-15, and the mechanical dynamic parameters of the vehicle described in equation (12) [7]
The results show that SOCsc remains within safe operating limits, leading to higher use of SC in transient regimes

Summary

Introduction

The world consumption of fossil fuels has been growing continuously for more than half a century. Fossil fuels are becoming scarcer by the day. This scarcity is accompanied today by a feeling of duty towards nature and the environment. Science is obliged to remedy, or at least minimize, the harmful effects of the consumption of fossil fuels and to be able to partially replace them. In this context, hybrid vehicles with a fuel cell (FC) are an essential solution for the future. Hybrid vehicles with a fuel cell (FC) are an essential solution for the future These vehicles are powered by a FC assisted by a secondary energy source (SES). In order to develop hybrid system simulators, it is necessary to couple dynamic models of the sources and the power converters
