parameterization of Simscape table-based battery model

Hi,

I am trying to create a charging profile for the simscape electrical table based battery model. I have feedback setup on the SOC and terminal voltage to control cell charging. I want to understand how do I set up the initial values of SOC and cell terminal voltage. And whats the difference between initial targets and nominal values? A video guide to setup and edit the battery model would be highly appreciated.

Hi @Haris,

Initial Target is for setting up initial conditions for a simulation. In the battery simulations, it is very typical to set up initial SOC and temperature. There is typically no need to set up initial terminal voltage because it is going to be decided by the load.

Nominal Values are for normalizing the variables to improve simulation robustness. See more details here: Use Scaling by Nominal Values to Improve Performance - MATLAB & Simulink.
