Abstract
The global demand for energy and the environmental impact study of fossil fuel consumption has gained worldwide attention due to its importance and is a topic of ongoing discussion among researchers and policymakers. Proposing an alternative and environmentally friendly energy source is therefore of utmost relevance in promoting sustainable mobility. This project proposes the development of a solution for a connection and charging control system for electric vehicles range extender using sustainable hydrogen generation and fuel cell utilization. The system to be studied includes a Proton Exchange Membrane (PEM) fuel cell with 5kW of output power, powered by a sustainable aluminum-based hydrogen generator and a sodium hydroxide aqueous solution. The fuel cell generates 70A at 72V, and commonly, high-voltage systems of electric vehicles are designed above 300V and until 900V, requiring a system that can accommodate the transfer of charge between the fuel cell and the electric vehicle. The innovation of this project lies in the absence of an “off the shelf” solution available in the market and the need for control in various requests and specific operating conditions. For the study, a demonstrator electric vehicle with a range extender system is under construction, where experimental data such as power, voltage, and current will be collected to aid in the development of a Matlab Simulink model for simulation of operation and determination of control parameters. The current Simulink model includes a closed-loop PID controller driving a boost-type DCDC converter for increasing the voltage from 72V to 400V. Its sizing should cover the operating range of both the fuel cell (60V to 110V) and the vehicle (300V to 400V) simultaneously. Preliminary results of this model show a good level of conversion and stability for an output voltage range around 350V using a PI-type controller, with convergence to the calibrated reference value (output voltage) below 5s.
