Second Life Batterie for Microgrid applications

I have data on PV production and household consumption. My goal is to use this data to form a BMS system to intelligently control the power flow in a microgrid.

I am trying to develop a model of an electric car battery but I don't know how to insert the data into an equivalent circuit. What data should I take from the battery specifications to form a complete model? I know that the Equivalent circuit of a battery has three distinct time constants, internal resistance, and open circuit potential.

All the references I find show that I must take measurements on a real battery, but I don't have a battery to do the tests. How can I get an equivalent circuit from an electric car battery that I can use, for example, in a microgrid?

Best place to start when designing and simulating battery packs is Simscape Battery, a new toolbox introduced in R2022b. There are several examples from building the battery pack to designing BMS algorithms. The Battery (Table-Based) offers also pre-parametrized cells from different manufacturers.
