What's my REAL usable battery?

^^^all of the above, but really, if you're having range anxiety in Montana, I'd strongly recommend dropping down from the 80-85mph. Seriously. Even a drop to 75mph would add a significant amount to your range.

The biggest problem we have in Montana is "we have two seasons --- 'winter and construction season.'" After the new pavements are laid down, they then seal and chip them. Windshields take a real beating here. So if you don't keep up with the flow, you have those few that have to be in the lead. They fly around you - pull back in front of you - that's where the excess stone chips get flung into your windshield. I'll try to drop down to 77 or 78 and see if that helps. I'm might be and old man, but I don't drive like one...

Oh, and about anxiety and charging. There are options. There are probably level 2 chargers where you're going? You can plug there and gain a few percent, wait longer if you have to. Worst case a 120V plug works and there are billions of those everywhere. Do not just think of superchargers. Maybe abrp won't tell you but you know...
I'm saying you won't be stranded unless you do it on purpose. It might simply be slower than you'd want.

Options with level 2 chargers in my area are nil to none. The idle time that I stay at some of my destinations might be an hour or less. I also use Plug Share - it does a pretty good job of picking even the slowest of public chargers. On a recent out of state trip - I did plug into the casino's 120v over our stay and gained a free 25% charge (that was nice.)

For more range you might try a little more air in your tires. I run 46 in mine instead of the recommended 42.
I'm pretty sure the casino made enough from you to more than pay for the electricity you used charging your car.
25% of 75 kWh is about 19 kWh. I pay 9¢ per kWh so that would be $1.71

I run 45~47 psi when hot. Ya, the casino paid for the 19 kw - but I paid entertainment (aka, gambling,) room and board. The residential rate in our part of Montana is about 12¢ per kWh. The last supercharger that I used in Washington state was 36¢ per kWh. I'm glad I charge at home.

We all seem to switch from miles to %. It woks better.

It works better for some people, not for me and the wife. Just a personal choice for people. I did the opposite. Started out using % for about two months and switched. Been using it ever since. My brain is twisted differently. This debate has gone on for years.

 

[Feathermerchan]

When tire pressures are listed they are cold unless specified otherwise. The hot temperature is irrelevant.
I run 46 psi cold.

 

[Pianewman]

(Tesla recommends 42psi. I've tried 38-44. If I ran 45psi, on DFW broken highway, I'd require serious dental work, and suffer from renal failure. Chiropractic adjustments would NOT be necessary, for obvious reason.)

YMMV.

 

[Feathermerchan]

Well I have the benefit of light forged 18" wheels and tires with a sidewall. Not what came on the car.
BTW I'm in DFW and have had no special dental work.

Feathermerchan: Thanks for the clarification. As usual, we have to be careful when we discuss ride characteristics.

What tires/size? Can you drive at 45mph on Plano Pkwy w/o going airborne?

 

[Feathermerchan]

Tire size: 245/45-18 Ride was immediately improved with wheels and tires. Still fast enough to scare me.
I live in the Mid-Cities so not often in Plano.

Did you see any range impact when you went with the new tires?

 

[Feathermerchan]

Yes. Increase in range. Probably about 20 miles. Most highway I driven on one charge is Texarkana - Euless. About 195 miles at 40 degF and night. Left with close to 100% charge and had about 15% left when I got home. That's about 229 miles to 0%. Some of the way speed limit is 75 the rest 70 until you get into Dallas. Mostly drove speed limit.

 

[Geech72]

Nice range increase. I really love my 20in induction wheels but know I’m trading the look for better ride and range.
