Trip planning - elevation change

[TonyR67]

Is there a rule of thumb for miles to add to a trip for elevation gain, such as add so many miles per 1,000' of elevation? I believe I read some where else that there was such an estimate, but I forgot where. I'm brand new to all this, and I have an upcoming trip that's 188 mi long with an elevation gain of about 2,000', temp will be around 25º or so.. I think I'll be fine, but I'd like to get a better idea.

Thank you,

Tony

You can use a site like abetterrouteplanner.com or evtripplanner.com to plan your trip and see the estimated energy usage. Both will take elevation into account.

In the Model S it was calculated that it used 6 miles of range per 1000 ft. elevation. I haven’t seen anyone calculate it yet for the Model 3 but it wouldn’t be any more than that.

Thanks! That evtripplanner was a big help. The trip will be a breeze.

That was it. I remember reading that when I was thinking of getting a Model S years ago.

It’s about 1.7 kWh per 1000’ elevation gain for a 4000 lb car, which is 5-7 miles depending on Model 3 version and driving habits.

Ok. that helps.

Unless the altitude change is substantial. Don’t worry about it. The only real concern is being certain you have sufficient charge left at the top in case of unexpected happenings. An example I was sitting in Hilo with 104 miles of range showing and the car said no problem reaching my house in Kona over the Saddle road ( 6600ft higher). However, at the crest it showed 12 miles left and 40+ to go. When I got home it showed 32 miles left, exactly what it projected. However if there had been any woops I could have been in a world of hurt(no cell). After that, if the car showed less than 125 mi of range, I would get a splash first. Other than things like that, don’t worry.

I have an upcoming trip that's 188 mi long with an elevation gain of about 2,000'

I’m sure you will have no problem on that trip if you start out with a 90% charge (no need to go to 100%).

But for trip planning I highly recommend the EV Trip Optimizer app. See tesla_to | Digital Auto Guides

So what exactly is the car doing when you plan a long trip and it suggests super charger stops; are we saying it doesn't include some provisions for altitude changes? That would seem an oversight? Or are you guys 'wild westing' it and doing all the calculations yourselves?

Thank you all. Big help.

I live uphill from work. Travel down then up ~1000 vertical feet over 8 miles every day. For my trip home I typically see about double my “average Wh/mi. For example right now since May 1 my average is 227 Wh/mi. And yesterday I charged at work and my Wh/mi since last charge (on the way home) is 390. In the winter with the heat on I’ve seen 600-700 Wh/mi for my drive home.
