1. ### The battery equivalent internal impedance equation

Yes, this look familiar and makes new thoughts about the solution. I will report back if this succeeded during this week. Thank you
2. ### The battery equivalent internal impedance equation

My what? You mean how much do I know about electrical "stuff"? not much. Edit. Yeah... No I see my problem. the capacitors are confusing me. So technically, resistors are in series, aren't?
3. ### The battery equivalent internal impedance equation

Did some googling again and found out that R (in this case z) should be calculated: 1/Rrc = 1/R_transient_s + 1/R_transient_L, where Rrc is tmp variable Z_eq = Rseries + Rcycle +Rrc
4. ### The battery equivalent internal impedance equation

Right.. the units.. now it makes no sense. Z_eq unit is Ohm. And in this "equation" it will be [Ohm] +[Ohm] + 1/[Ohm] +1/[Ohm]
5. ### The battery equivalent internal impedance equation

If I may, I would like to (not sure yet :-) ) add your note to presentation. So Z_eq =Rseries + Rcycle +1/R_transient_s + 1/R_transient_L then?
6. ### The battery equivalent internal impedance equation

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...
7. ### The battery equivalent internal impedance equation

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 I assume...
8. ### The battery equivalent internal impedance equation

Homework Statement 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: Homework Equations Values in...
