“…In this case, a low-frequency part of the fuel cell alternating-current component, which is formed in transient modes when the load changes, is mostly compensated by battery connected in parallel with the load and with the help of a regulator that controls the voltage converter. The main high-frequency part of the fuel cell alternating-current component is caused by the operation of the voltage converter, although this fact is not found in the publications known [1,[7][8][9][10][11][12][13][14][15][16][17][18].…”

“…The equivalent scheme parameters are determined by experimental data. The difference of this circuit in comparison to the more widely used types [1,2,[16][17][18] mainly consists in the influence of dynamic losses in conductors. Obviously, this influence is present and might be quite significant if caused by rapidly changing large currents.…”

The aim of this work is to develop a dynamic equivalent scheme of the fuel cell, taking into account eddy currents in the conductive parts of the structure, to offer a practical way to determine the parameters of this circuit and also to show the adequacy of the scheme and parameters by numerical simulation and comparison with experiment. Fuel cells, as a rule, are connected to the voltage converters, which create a high-frequency component of the main fuel cell current and eddy currents in the conductive parts. The problem is that the effect of these currents on the characteristics of the fuel cell-based power plants has not been studied. To determine the parameters of the proposed equivalent scheme, we use experiments and calculations of transient modes of the fuel cell. The main result of the work is the possibility and feasibility of calculating circuits with fuel cells, taking into account the influence of eddy currents. This effect depends both on the design of the fuel cell and on the parameters of the circuit to which it is connected. From this it follows that, in general, it is necessary to take into account the influence of eddy currents of the fuel cell. The refusal of this accounting is possible, but in each specific case it must be justified.

“…The calculation formulas are tested on a computer model in the LTspice IV program (Figure 9) and demonstrate good agreement with the simulation results. The deviation of the calculated data obtained by Equations (11)(12)(13)(14)(15)(16)(17) from the data obtained by modeling the circuit in the LTspice IV software was estimated by determining the relative magnitude of the error under various operating modes. The calculation error was determined for the amplitude, mean, and effective values of currents and voltages of the circuit according to the equation…”

The issues of mathematical and numerical simulation of an electrical complex of a power plant based on hydrogen fuel cells with a voltage step-down converter were considered. The work was aimed at developing a mathematical model that would provide for determining the most loaded operation mode of the complex components. The existing mathematical models do not consider the effect of such processes as the charge and discharge of the battery backup power supply on the power plant components. They often do not consider the nonlinearity of the fuel cell output voltage. This paper offers a mathematical model of an electrical complex based on the circuit analysis. The model combines a well-known physical model of a fuel cell based on a potential difference and a model of a step-down converter with a battery backup power supply developed by the authors. A method of configuring a fuel cell model based on the experimental current–voltage characteristic by the least-squares method has been proposed. The developed model provides for determining currents and voltages in all components of the power plant both in the nominal operating mode and in the mode of limiting the power consumed from the fuel cell when the battery backup power supply is being charged. The correctness of the calculated ratios and the mathematical model has been confirmed experimentally. Using the proposed model, a 1300 W power plant with a specific power of 529.3 W∙h/kg was developed and tested.

“…The fuel cell subsystem's complexity made its dynamic response worse and was adversely affected by the surrounding work environment. A simplified model was established with reference to the models of [17], [18]. Parameter identification and data fitting are common methods to improve the accuracy of the simplified model and make its applicability easier to understand.…”

Influence and Optimization of Packet Loss on the Internet-Based Geographically Distributed Test Platform for Fuel Cell Electric Vehicle Powertrain Systems

et al. 2020

In view of recent developments in fuel cell electric vehicle powertrain systems, Internet-based geographically distributed test platforms for fuel cell electric vehicle powertrain systems become a development and validation trend. Due to the involvement of remote connection and the Internet, simulation with connected models can suffer great uncertainty because of packet loss. Such a test platform, including packet loss characteristics, was built using MATLAB/Simulink for use in this paper. The simulation analysis results show that packet loss affects the stability of the whole test system. The impact on vehicle speed is mainly concentrated in the later stage of simulation. Aiming at reducing the effect of packet loss caused by Internet, a robust model predictive compensator was designed. Under this compensator, the stability of the system is greatly improved compared to the system without a compensator. INDEX TERMS Fuel cell electric vehicle, powertrain system, Internet-based distributed test platform, packet loss, robust model prediction compensator.
