Simscape Battery Block Parameterization Manager: Datasheet Derived Values for Terminal Resistance R0 of Molicel Battery Cell

Hello,

i am using the Block Parameterization Manager: Battery (Table-Based) to use pre-parameterize battery cells in my Simulink Simscape model. I am wondering where some data is coming from, specifically the values for R0 (Terminal Resistance) of the Molicel INR_21700_P45B.

In the manager, its says datasheet derived. Is it possible to view this datasheet somewhere? Is there a database for it?

Thank you very much for your help!

The datasheets can be typically found on the manufacturer website, in this case here: https://www.molicel.com/wp-content/uploads/INR21700P45B_1.2_Product-Data-Sheet-of-INR-21700-P45B-80109.pdf

Hello Fynn-Brian

Thank you for your question.

The internal resistance is calculated based on pairs of constant current discharge curves as R ~ deltaV / delta I.

Please let me know if you have any other question.

Best regards,

Javier
