2 RC model

[Astor00]

Hi, I am trying to make a 2RC equivalent circuit model using your EKF model. What changes do I need to make in order to run the simulation successfully?. Any help would be appreciated. Thank you.

The 2RC equivalent circuit model contains another RC component than the Thevenin model. So I think you need an extra pair of RC parameters with its process noise, and to scale up the corresponding matrix P and Q in EKF.

I did all the required changes , but the output isn't as expected. But, if I change the P and Q values the results do get better but still not similar to the Coulumb counting SOC. So is there any way to tune these values or do I have to just do trial and error and check it everytime ?
