In this picture, there are 2 subsystems in this model (simulink). For first one, I have equations to calculated all R and C values. However, in second subsystem I need to calculate a Z_eq in given values. Here Z_eq is battery equivalent internal impedance [ohm].
The catch for this task is that...
For Mathematical modeling of engineering systems course :).
Its for individual assignment. We had to find an article with some matlab/simulink model and try to simulate something with it.
All other equations are given in the article, except this.
Edit: I did not want to double post
Hello, long story short: I need to create a model of Li-Ion battery and I'm stuck on calculating the battery equivalent internal impedance. The thing is, I don't know the equation or even how to make one. However, I have a circuit drawing:
