Hello,
I'm currently trying to implement a batterypack in Simulink using simscape. Each cell is modeled with 2 RC elements, a serial resistance and an OCV Voltage source. I know connected 20 of those cells in parallel and 2 in serial. What i want to do now is to be able to vary the number of cells in parallel and serial connection. I thought of implementing switches that would open or shortcut not cells based on a set variable (e.g. if VarSerial=2 the battery pack would consist of to serial cells.If VarSerial=1 all serial cells should be shortcutted) but each switch comes with an internal resistance that can't be set to zero. Is there any way to implement my model? Maybe with an enable block?
Regards

I checked your model, the only useful way that I could find is using Variant Subsystem. It enables you to select any subsystem that you want and you wouldn't have to delete the cells by hand. For more information, see the link below:

No, it is. Right click your physical subsystem, go to Subsystem&Model Reference->Convert Subsystem to->Variant Subsystem. It automatically creates it for you.
