Battery modelling (lithium-ion)

Greetings,

I'm trying to model a battery for an E bike using set of known equations, which includes modelling both thermal and equivalent circuit model. now I'm having trouble in establishing relationship between them ie How should i establish a relationship between output of thermal model (Temperature) as an input for equi circuit model?? i did check few sources but nothing explained clearly. Also, i don't have simscape in my license, so i can't check how its modelled.

Any valuable input is much appreciated. thankyou
