“…Some papers in the literature analyze and compare different PDSs based on fuel cells and batteries [7,8,11,13], based on fuel cells and supercapacitors [9,[14][15][16][17], and, finally, based on fuel cells, batteries, and supercapacitors [10,[18][19][20][21][22]. In [23], a complete analysis and comparison of 10 different power distribution systems are presented, considering all the possibilities in powertrain implementation (fuel cell and batteries, fuel cell and batteries and supercapacitors, fuel cell and supercapacitors).…”

The design of the optimal power distribution system (PDS or powertrain) for fuel cell-based vehicles is a complex task due to PDS comprising one or more power converters, several types of secondary energy sources, a fuel cell, several control loops, and protections, among others. The optimized powertrain design tries to minimize the mass, volume, and cost, and also to improve system efficiency, fuel economy (both hydrogen and electricity), and vehicle autonomy. This paper analyzes the influence of four different factors that deeply affect the optimal powertrain design, in particular: the minimum power delivered by the fuel cell, the storage of the recovered energy from the regenerative braking periods, the battery technology, and the maximum battery state-of-charge variation. The analysis of these factors is carried out over a set of 9 different fuel cell-based architectures applied to a light vehicle, and a 10th architecture corresponding to a pure electric vehicle. This analysis provides the knowledge of how these design factors affect the mass, volume, and cost of the optimal power distribution architectures, and how they can be considered in the design.

“…In the vehicle configuration of [6], UC and FC units are connected directly together without any DC/DC converter. In [8], optimization of the battery and ultra-capacitor units are gained based on Ragone plots. The authors in [8] also considered the delay of the system in optimization algorithm.…”

Electrical energy generating (fuel cell) or energy storage device (such as battery and ultra-capacitor) are commonly used to provide the propulsion energy required in vehicles. Design of these energy generating and storing components in terms of efficiency, lifetime, cost, size, weight, and also fuel economy is highly important. In this paper the number of fuel cells, batteries, and ultra-capacitors in a fuel-cell electric vehicle are optimized. In the optimization method, the power converter and components mass and cost are considered as optimization parameters. In order to achieve this, an objective function is written based on the above-mentioned parameters. Simulation results verify the optimal design. Finally, for better understanding the results are compared with previous related works.

Abstract-This paper highlights the renewed by the cycle of nature and are controller of a bidirectional converter to considered to be practically inexhaustible [1-interface an ultra-capacitor as storage 4]. As a result, the future of these sources as a device to renewable energy systems. Ultratypical alternative for the traditional sources capacitors are typically used in renewable looks very bright energy systems to improve the system's However, the natural variability of reliability and energy conversion some renewable sources due to their strong efficiency. The controller of the converter dependence on the weather conditions result system has been designed and simulated to a high fluctuated output power, which based on the integration of both Current impacts on the local loads that are sensitive to Mode Control and Linear Quadratic pulsating power [5][6].
