How does Simscape derive the state of charge, temperature, and terminal voltage from an input current in the battery models?

In the various simscape models for batteries (Lead-Acid Battery, Lithium-Ion Battery With Fault, etc.- all located under Simscape >> Physical Modeling >> Electrical Models >> Electrical Systems), the current is an input that can be adjusted manually in the Signal Builder or brought in from a file. The outputs the model gets from this are voltage, state of charge, and temperature. How is this occuring? What equation or set of equations is the model using to take the data for current and map it to the other three?

Thanks

Hi,

The Documentation for battery model mentions the equtations used in the model. You can also refer to the refrences attached in the end of the documentation.

Hope it helps !!
