Hill Climb in EV

From the above I conclude that speed has more of a detrimental effect on range than climbing hills.
The (static) energy needed to move the car is friction resistance plus air resistance (and these 2 don't depend on the inclination), plus gravitational potential energy from the inclination (and this doesn't depend on the speed), so the one with the most "weight" is variable ;-)

So no matter how fast you're going, you'll need 6,19kWh to climb 1520m with 1495kg (on my previous Leaf, that would represent 33% of the total capacity), and this is just the gravitational component of the total energy, you still need to add the "movement" part...

What varies a lot in mountain climbing (and that's why most people get huge consumptions in this situation) is dynamic power. When driving straight you accelerate to a given speed (dynamic power + static power) and after that you just maintain the speed (only static power). When you're mountain climbing, especially with lots of curves, you're often accelerating and decelerating, accelerating again, ... Depending on how "sporty" this driving is, you can spend a lot of additional energy in it.
You probably did it steady and smoothly, which would explain why you feel climbing is not such a big deal.
