Hey everyone, hope all is well. I am curious to see how I can model my battery in the single-phase battery system to model the SOC of the battery. I am seeing equivalent circuit models online, but I am not sure how to build one. I am just looking for a starting point on how to simulate that. Thanks if you can help, it’ll be much appreciated

Hi brandontm85, have a look at this application note and let me know if that is what you are looking for: [Electrical Equivalent Implementation of Lithium-Ion Batteries | Plexim](https://www.plexim.com/content/electrical-equivalent-implementation-lithium-ion-batteries)

hope this helps!
