How do i calculate the parameters (E0, K, R, A and B) in generic battery model?

Hello everyone,

how were the following parameters (E0, R, K, A and B) calculated. I know that the battery model shows this parameters directly with the plot function. But I want to know the background calculation. I look forward to your reply. Thanks.

These parameters can be derived from a datasheet. Usually, some parameters such as rated capacity and internal resistance are provided. Other parameters can be derived from the discharge characteristic.

Alternatively, a series of experiments can be performed to estimate the parameters using either Hybrid Pulse Power Characterization (HPPC) or Electrochemical Impedance Spectroscopy (EIC). To learn mor about these methods check out the Simscape Battery documentation:
