Supposedly, Nissan does that thorough CarWings now, and if you plan a trip using their route planer, historical data will considered. I haven't used this new functionality myself and can't really say how accurate or useful it is. Elevation differences are not all that hard to consider, and it's surprising that most EV manufactures don't even make an effort.

I don't have any of that. I bought a "s" model :(

Do you have an iOS device? Just download "LEAF Energy" if you do. It will work with dash instruments. Many of us early LEAF owners did not use CarWings much, because it delivered erroneous energy readings in the past.

Is that a smartphone or a tablet? I am planning on getting one of those, but still trying to figure out which one to buy. I also need the apps to find charging stations. Right now I just have a handwritten list in the glove box!

Hm, the easiest thing would be an iPod, even an older model, which could be used on wifi. Also, a prepaid Android phone would be good too, even though "LEAF Energy" will not work on it. At least you could run Jim's battery app, which is very useful. Elevation differences are not as much of a stumble as they might appear. It just takes some getting used to. Whatever you decide to do, getting PlugShare installed could be quite helpful for finding charging stations!

when I took my trip I just used physics (Work = force times distance) to figure out the energy used to climb a hill. I figured 2000 feet cost me 25 miles. If I go down 2000 feet I get 13 miles back. I mapped out my whole trip to spokane that way using google maps terrain feature, and I was pretty much dead on with my estimated charge usage.

Right, good to hear, that makes complete sense. How do your calculations agree with Tony's estimate of 1.5 kWh per 1,000 feet of elevation gain?

mine was more conservative. I figured 4.3 miles per KWH, so my 25 miles for 2000 feet would have been more like 15 with his calculations. I'll have to look into it further the next trip I take.

I am trying to make; Hope to Merritt , I guess my first post was not clear when I said "to Merritt, BC from Hope,BC" This is starting at sea level, going up to 1,200m and ending at 600m.

Based on carwings, it is not possible... It does not have any historical data, does not look like anyone tried before.

I am going to try it once the fast chargers are installed at hope and merritt, or maybe if i have a whole weekend free...
