Your statement is equivalent to saying that

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?
