Your statement is equivalent to saying that

dS/dt = f(I)

But how do you know that the rate of change of state-of-charge at a given instant in time depends only on the instantaneous current at that time?

For example, how do you know that dS/dt is a function of I only, and not, say, a function of both I and S: dS/dt = h(I,S) ?

This would make an interesting pre-season project.


What is the definition of state of charge?

I know that a "fully charged" battery should have 100% charge, but what is the criterion for a battery to be 0% charged? Would it be a terminal voltage of zero? For a given battery, is S a function of terminal voltage alone?
