Well, that is not the way I read it. I took it as a way to rate a vehicle
before you purchase it.
Not very useful IMO for that because there are so many other factors that one
needs to know in order for the vehicle to meet you needs.It is a start but
seems to me one would still need to know how many charge opportunities there
are between the start and end. In addition as already pointed out the rate of
charge depends on the current SOC in the battery. For instance, my Model S will
charge slowly if my SOC is too low until the voltage comes up and then it will
ramp down as it fills. All vehicles do this and without knowledge of the exact
algorithm the are using this simplification of Drivability may not be useful at
all.
The concept is good but the current suggestion will give you inaccurate
information that may or may not help you.

Paul, this is all about the few times you take a road trip and need fast
charging. So, let me ask you this question: for those few times, would
this kind of rating be useful to you ?
