How can i set initial soc for battery pack module built with battery builder?

Hello Community, i have been testing with battery builder and simulation. Here i have a sample battery pack module built, and could run simulation with it, however the soc of the module always starts with 1, is there a way i can directly assign a different value to it? I noticed there is this soc estimator available, but is it the same with directly setting the initial soc of the pack? Thanks

Hi @Sebastian Michaelis,

The generated battery module block has a block parameter called "Cell state of charge" which determines the initial SOC for the battery pack. Since this defaults to 1, the SOC of the module starts at 1. You can modify this block parameter to start the module with a different SOC value.

To manage the run-time parameters of the battery pack more conveniently from a centralized location, you can use the MaskInitialTargets and MaskParameters name-value arguments of the buildBattery() function to generate a script with all the initial values for different parameters of the battery pack. To modify any parameter, you will only need to modify the script and run it.

Please refer to the following resources for more information:

Hope this helps!
