Hi,
I am new to batteries and I fail to understand a basic thing - Why do we need to model batteries from application point of view?
I understand there are a number of different techniques to model - based on electrochemical process, mathematical equations and equivalent circuits.
What I do not understand is how do we use the model in the real world application?
Lets say we want to measure the SoC of a battery - we can use OCV and Coulomb Counting methods.
How does a model help in finding SoC or in monitoring the battery?
The only use of a model I can find is to use for simulation purposes. Does it have any other requirement?
It would be great if someone can help me better understand the benefits of modelling.
