There are all sorts of non-linear properties to batteries, not to mention each battery will be different, but I think it could be interesting to see how close one could get to an accurate prediciction given just the KoP electronics.

You might be able to simplify everything and just assume that batteries plugged in when the robot is turned on are at full charge, and then just use the current monitoring to figure out remaining charge, and apply some sort of derivative to extrapolate the remaining drive time. That might work well enough for a first guess, at least?
