Giving a sinusoidal current and obtaining EIS

[Akila1993]

Hi,

I am trying to use simscape-battery-library to run EIS simulations, by applying a sinusoidal current and measuring the responding voltage, from which I can extract impedance measurements.

1. Suppose that I am trying to use TSPMe, and in the following code how can I input sine input "appCurr".

import BatteryLibrary.Utilities.*
simuLinkMdlStr = 'TSPMe_Prototype'; % Specify the simulink file name (without the file extension)
load_system(simuLinkMdlStr+".slx")
set_param(simuLinkMdlStr,'SimscapeUseOperatingPoints','off');
Vmax = 4.2; % Set upper cut-off voltage [V]
Vmin = 2.5; % Set lower cut-off voltage for terminating discharge [V]

modelProp = Simulink.SimulationInput(simuLinkMdlStr); % Create an instance of a Matlab SimulationInput class to simulate

appCurr = -5*timeseries(1,0,'Name',"I"); % Generate 1C input current as a timeseries object (1C := 5A) [A]
modelProp = modelProp.setExternalInput('appCurr'); % Set the external input to the model

2. In order to calculate impedance for EIS, how we can extract current and voltage entries from the Matlab code?

Hope someone will help me in this regard.
