Abstract:In this study of zinc nickel single-flow batteries (ZNB), the ion concentration of the convection area and the electrode surface of the battery runner were investigated first. Then, the relationships between the electrode over-potential (or equilibrium potential) and the charge time were studied. This was based on the electrochemical reaction rate equation and the equilibrium potential equation, from which a mathematical model of the stack voltage (as affected by the internal parameters of the battery) was obtained. By comparison with experimental data, it was determined that the relative error of the simulated stack voltage of a 300 Ah battery was restricted to <0.62% while charging under the condition of 100 A constant-current charging. This shows that the mathematical model can accurately describe the dynamic characteristics of the battery stack voltage, and is very accurate for predicting the stack voltage of the battery during charging under 100 A constant-current charging conditions.

This paper intends to report and describe a variety of activities such as modeling, simulation, design, implementation, test and analysis in order to design and develop EMUBAT, a battery emulator for space applications. The first step of EMUBAT development is battery modeling which is performed by using a typical equivalent circuit. The required parameters for battery modeling are extracted by means of electrical characteristics curves which are presented in battery datasheets or obtained from battery testing. Then, the orbit parameter modeling is investigated for LEO and GEO satellites. Battery thermal conditions due to its in-orbit operations are modeled in the next step. Finally, the hardware configuration and the software structure of EMUBAT are described. Besides, a battery test setup is presented, which is established to facilitate the process of obtaining the required data and parameters, for EMUBAT modeling and simulation. This test setup also makes it possible to have an easier and more precise verification of the emulator outputs.

“…Comprehensive models have been employed to study battery cells such as lead-acid [4][5][6][7], nickel-cadmium [8][9][10][11], nickel-metal hydride [12,14,15] and lithium-ion [13,[16][17][18][19]. In designing a battery model, an appropriate model must be able to capture the species and charge transfer across the battery and the microscopic phenomena occurring inside the active material and across the electrolyte/electrode interface.…”

The concentration of lithium ions in the cathode of lithium ion cells has been obtained by solving the materials balance equation ac 1/2 D a2c ajn(l_t+ ) at ax ~ E by Laplace transform. On the assumption that the cell is fully discharged when there are zero lithium ions at the current collector of the cathode, the discharge time ta is obtained as "c = --ln +--2E1.2 J 6 which, when substituted into the equation C = ItJM, where I is the discharge current and M is the mass of the separator and positive electrode, an analytical expression for the specific capacity of the lithium cell is given as ~MDE 1/2 L-2-~. ~ ~-~-
