Kenny, thank you as that's what I was looking for. Have you given any consideration to adding the energy consumed by the vehicle itself? Whenever I turn on the car, CaniOn show the car consuming on the order of 1/2-kW (from memory), and as the car starts moving there must be additional IR and conversion losses (controller, motor), with a first approximation being that they're proportional to the current being drawn. It's these losses that force the curve to drop back down and result in range actually going down as the speed gets down below about 12mph.
