The only comments I can add that may be helpful are a reminder that current measurements made at the battery are observations of voltage drop across a shunt resistor. The measurement of current is used as a proxy estimation to evaluate the capacity status of the battery by making conclusions based upon expectations that the battery will present some level of resistance at some level of capacity.
With regards to the first comment, measuring voltage drop in a parallel array where the voltage in the system is constantly trending towards entropy may lead to abstractions that do not indicate the actual capacity of the battery. The current measurement will include both the effect of the primary function of the battery as well as the settling effect of the parallel array.
With regards to the second comment, as vehicle operators we tend to think in terms of cranking amps and the ability to power accessories, but an evaluation of a battery's effectiveness regards the capacity of the battery to repeatedly perform the function required. A current measurement represents an instantaneous state, while we are more often concerned with long term performance. As you suggested the IBS and BCM are capable of considering more than a single measurement. I think that seems to be a good thing.
These discussions have created a question in my mind; What is the expected benefit of the Intelligent Battery Sensor?
Is it primarily implemented to enable the charging system to be effective while the vehicle manages for maximum efficiency when harvesting the kinetic energy from the vehicle's motor, or is it primarily intended to maximize the health of the battery?
Does the system address one concern at the expense of the other or is the advent of this technology a panacea that optimizes the achievment of both goals?
Thank you for the discussion.
