How does battery table-based works in Simulink?

I don't know how to see the parameters of my battery when I run my model.

The problem that I have it's that Simulink asume that the SOC is 100% and I don't want this case, does anyone know how to fix it?. Sometimes the SOC is negative and this it's imposible but it works and it shouldn't.

Another question I have: how I can start the model with a nominal voltage? The model always start with SOC =1.

Thank you

Hello Sandra,

I understand that you want to customize the SOC level in the battery and introduce a nominal voltage to your model.

Simscape provides the Battery block, which implements a generic dynamic model that represents rechargeable batteries. There are several parameters like Nominal Voltage, Rated capacity, Initial state-of-charge that you can adjust according to your requirements.

To customize the SOC level, you can use the Initial state-of-charge parameter.

To start the model with a nominal voltage, you can use the Nominal voltage parameter.

You can refer to the below documentation to understand more about the parameters.

Does this mean that a "battery table-based" system can only be used in discharging mode, because we can't customize it to suit our needs?

Because if we charge it the SOC always start from 1 (100%), which is impossible.
