If you look at the help page on the Battery model in the PSCAD library, the votlage equation is given as:
Where the exponential zone time constant inverse 'B' is definded by: B = 3.0/Qexponential.
and Qexponential is decided by the user in the edit parameters window "Capacity at Exponential Point".
Hope this helps! :)
