Hello,
How would I write this question in simulink using simple blocks:
V= I*R*(1 -exp(-t/(C*R)) ?
I think I am missing the feed back which decays the value over time.

I don't want to use blocks which lock values (R and C), as I want to create lookup tables which change the valuse later on. (this is for 2-RC branch battery model)
Any help would be greatly appreciated!

That is moving in the right direction. Will I always need to select a time constant? or can it be linked to the simulink time?

It depends on your design. You can either select a time constant manually or you can link it to Simulink time.

Can you use the 'Ts' block to do this?
Also, can I write my exponential function in terms of a transfer function?
