I am studying mathematical modeling of a battery in simulink and for this it is necessary to determine some parameters. I'm stuck in the part where I need to determine an alpha parameter, which would be the relation between capacity and temperature. Not all battery manufacturers provide this parameter and would like to know with the author or how I could get to the value of it to proceed with the study of the model. Below the discussion that deals with the subject and attached the paper about it.
Looking for some manufactures data I found a data sheet with some informations I think can help me. So, with this specifications what is the value of alpha ?
