X: What's your 90%?

[SageBrush]

I understand it isn't the most scientific result but it also roughly half... My day to day life isn't made up of 70mph constant speed driving and especially without AC out here

But the EPA mostly is, and it most certainly is not performed at summer temps in AZ.

The good news for your range concerns is that AC use will moderate over a long drive.

Next weekend is a 400 mile each way trip. I should get some extended highway numbers then.

The AC in the S doesn't seem to hit the range very much at all. In the X, I notice a much bigger difference. I continue to believe that's due to some issues with early AC units - replacing condensers, lines switched, coolant leaks, etc., but I could be wrong. It just doesn't make sense it would hit so hard.

I'm consuming about 335Wh/mi around town. That's generally in line with EPA, depending on how much of my pack is actually usable.

My consumption around town varies significantly, on a good day it is in the mid to high 300's, on a bad day over 400. Temps and humidity have been very high here, I think that the extra consumption is from battery cooling.

I think the biggest difference between the S and the X (pure speculation) is that the X has dual air conditioners. I often turn the back one off but when it gets really warm I use both of them to get the temp down faster.

Reasonable hypothesis. I also turn the back one off, but I haven't done any real analysis one way or another. The X also seems to gets hotter, possibly due to the windshield.

See Poor efficiency at high ambient temperatures for a very, very small amount of data which supports this hypothesis.

I have about 5000 miles on my X90 and am down to 227 miles at 90% charge. This thing keeps declining in range.

May I ask how often you supercharge, and what your charge limit is set to?

 

[ohmman]

Don't forget that the algorithm is estimating your actual range. You can recalibrate that if you're truly concerned. Plenty of threads in the Model S forum discussing this same phenomenon.

 

[jrichey]

Interesting for me that just last week (after about 1 month of ownership) my 90% has gone from 211 to 214. Like that trend a lot, just unexpected. As for super charging, I have only done it 3 times.

 

[joebob73]

@KaiserSoze, When I first got my car, I picked it up from Fremont and drove it back down to LA. On that trip, I probably supercharged 3 times. I've owned the X for about 5 months and super charged about once or twice every month. I charge to 90% typically except when going on a long trip. I've probably had it at 100% about 4 times so far.

@ohmman, I've run the car battery down to the teens (percentage wise) a couple of times and the 90% charge rate is still about the same (just declining over time).

@ohmman, I've run the car battery down to the teens (percentage wise) a couple of times and the 90% charge rate is still about the same (just declining over time).

The balance requires a range charge after running it down. Did you do that, or only charge to 90% afterwards? If you're concerned, I suggest trying to run down to the single digit % and then range charging. Just run out for a drive immediately after to keep it from sitting there.

I will give it a shot. So run it down to single digits and then a charge to 100%. Will do. I'm taking in the X for service tomorrow so will have to try this when I get it back.

Looks like someone can use a sunshade...

 

[volkerbradley]

My 90 is 225 thus far. I leave Merlin plugged in when he's in the garage so no vampire drain overnight.

Hmm, I leave mine plugged in as well. However, after the charge to 90% is completed, the system behaves as if it is no longer connected to the charger. I still get 6 -8 miles of vampire drain during the next 24 hours.

209-210

(X75D)

 

[ModelIII]

90% charge on two month old 90D that has never been charged above 90%.

 

[travwill]

I'm surprised lately how at 100%:

a 75D is 237 miles.

15kWh more for a 90D, nets you +20 miles, for 257.

just 10kWh more for 100D, new pack, nets you +32 more, for 289.

Is the weight that different or limited in the new 100D pack, very interesting overall.

 

[EVKevin]

just 10kWh more for 100D, new pack, nets you +32 more, for 289.

+39 miles for 10kWh if you do an apples to apples comparison of P90D (250) to P100D (289) range.
