Electric vehicles are increasingly being adopted due to environmental awareness and competitive technical performance and reducing prices. Their research and development has sometimes relied on the use of standard driving cycles. However, these cycles cannot reproduce the variations of traffic flow in real world. That is why in this paper we develop a software tool able to analyze real-life driving...
Energy Storage Subsystems (ESSs) are more and more used in Fuel Cell Vehicles (FCVs) to face the problem of the lifetime and cost of the fuel cell. In this paper, a FVC using supercapacitors is considered. Two different control schemes are deduced from the Energetic Macroscopic Representation (EMR) of the system. Comparisons are provided for an urban drive cycle.
Nowadays, no electrochemical energy system presents a competitive operation if compared with internal combustion engine, which is the reason for combining electrochemical energy systems to obtain a hybrid energy storage system. This paper presents a fuel cell-battery-ultracapacitor system for vehicle application. The objective of this paper is to present the Energetic Macroscopic Representation (EMR)...
Energy storage systems undergo an intense application in both stationary and vehicle applications. Supercapacitors in particular present interesting proprieties due to its high power characteristics. To study and analyze its dynamic behavior it is necessary to apply test procedures, such as electrochemical impedance spectroscopy. However, the classical way in which these tests are carried out are...
Nowadays, hybrid energy systems have a great applicability for both vehicle and stationary purposes. The design, development, and testing of these systems are not straightforward due to the high number of elements involved, the complexity, and cost. Hardware-in-the-loop (HIL) is an appropriate approach to simulate the hybrid system as it combines both physical and simulated elements. However, the...
Hardware-in-loop (HIL) is an interesting methodology for developing and testing the operation of components in a complex system. In this paper, HIL is applied to a hybrid fuel cell/battery system that can be usually found in electric vehicles or peak-loaded stationary applications. The fuel cell is modeled dynamically in Matlab/Simulink by means of current interrupt tests. The system includes a dynamic...
In this investigation a test bench for the simulation of hybrid power trains combining fuel cell and batteries is proposed. The developed test bench offers a high flexibility as different fuel cells, batteries and loads can be tested in the power train in an effective and affordable way. The fuel cell is simulated with a dynamic electric model and a power source, which enables the simulation of fuel...
