Estimated Resistance

Block resistance values reported by OBD are suspected to be inconclusive, or at least they show a strange behavior:

User Lesolee from the Toyota Owners Club forum, suggested to apply Ohm's law to calculate resistance of each block based on measured voltage and current.
So, for each measure of every block, current and previous voltage values are used to calculate a delta V, which is divide by delta I, obtained from current and previous battery current value.
