FWIW, if it was an option, I probably wouldn't use it. To me, it seems like a waste of energy (electrical energy from the wall) and I actually prefer a little less re-gen in the winter anyway. But options are always good.

I'm the opposite. The only reason I preheat the car is to get my normal regen back. Ii would be a good option if on the iphone app under climate control they had "battery" or "cabin".
But the energy is used either way, assuming you drive far enough to heat the battery.
Yeah, I'd like it as an option.
Took a trip this weekend, and I preheated the car for about 20mins (it was probably 40F in the morning). Maybe 5-10mins into the drive, the full regen was back. But it was hot in the car when we initially got into it...
Today in the morning it was <40F, and I didn't preheat it as I didn't need the extra regen. 30 minutes of city/traffic driving, and I get to work and still didn't have the full regen available to me.

Yes, I suppose that is true. I do pre-heat my car in winter, but it's really to heat the cabin. The battery just comes along for the ride. I cannot imagine a scenario (myself) when I'd want to just heat the battery and not the cabin... but as I say, having the option is always a good thing for those that do.
Of course if you've left range mode on (as those of us with Ds may do, because we may want the torque sleep benefits) then the battery WON'T come along for the ride when you heat the cabin, even on shore power.
So those of us with Ds who use range mode by default when we drive, because we want the full benefits of torque sleep, have to remember to turn range mode off when we get home, and back on before we depart if we want the pack to heat when we heat the cabin.

Curious why John would be coming out to a "stifling hot interior"? On Auto, the HVAC should throttle back when the interior is up to temperature and just hold it at your setpoint. At least that's how mine works.

Interesting. Now that I have v7 firmware, my RWD car is supposed to have Torque Sleep as well (according to the Release Notes). There was nothing anywhere about needing to be in Range Mode for it to work. Do you suppose I would need to be in Range Mode for it to work on my car? Based on my driving patterns, I never found Range Mode helped me at all in the winter, but I do often use it in the summer to keep the a/c compressor down to a dull roar.

I do pre-heat my cabin in the winter (usually 20 minutes or less) and yes, I find that I don't need the seat heaters at all.
There's really no way to tell, based on what we've heard about the Ds' range mode and its impact on torque sleep, and the little we've heard about torque sleep in non-Ds.
Supposedly, based on e-mail correspondence from Jerome Guillen posted here, torque sleep in the Ds works with range mode on or off, but the full benefits of torque sleep are only available with range mode on.
I don't think there's any way to make any reasonable conclusion about torque sleep and range mode in the non-Ds based on that. Sorry.
Elon Musk tweeted, seeking suggestions for version 7.1 improvements:
I don't really use Twitter, but did tweet the following:
"Option to preheat traction pack when on shore power to eliminate regenerative braking limit, independent of range mode setting."
I'll also follow up with another email message to [email protected], including a pointer to this poll / thread. Perhaps now that Tesla has added battery heating as an option with Max Battery Power, it will be easier for them to also offer battery heating to eliminate the regenerative braking limit.

I would like the option of preheating the pack even when not on shorepower.
Since I'm not on Twitter, if someone agrees with me may they request the ability to remotely activate seat and steering wheel heat as well as the rear-window defroster?
Also nice would be having the Android app catch up with the iOS one. The notifications function that is not in Android was available over three years ago in the Nissan LEAF.

In my tweet I mentioned shore power.
I didn't think I had in the letter sent last February, but checking just now, I had in that letter as well. In the letter I send this time, I'll request the ability both on and off shore power, with the idea being that if shore power is available it should, of course, be used.
I think when you enable range mode, the dialog that pops up mentions the impacts of the range mode - on the Ds it mentions something related to torque sleep (different wording). Might be worth checking what the car says when you enable it.
I just sent the following letter to [email protected]:

Dear Tesla Technical Support Specialist,
I am writing in response to Mr. Musk’s recent tweet, seeking input on desired features and functionality improvements in version 7.1 of the Tesla firmware. I trust that you will pass this along to the appropriate department.
I first wrote to Tesla requesting a battery preheating option in February of this year. Those of us that live in cold climates often have to start our drives with regenerative braking limited. If we were able to preheat the battery, we could avoid this regen limit, and the car would provide a more consistent regenerative braking experience.
One thing many owners in cold climates do is attempt to time our nightly charges such that they finish shortly before we need to leave in the morning, so that the battery is still warm from charging. There are difficulties that this presents, and sometimes it just isn’t possible, but even when it is possible, this won’t completely eliminate the regen limit in very cold climates.
Many of us will heat our cabins, in an attempt to partially heat the pack, and somewhat reduce the regen limit. But to the extent that we may not even want the cabin heated (or heated that long), this is wasteful. Also if we have range mode enabled, heating the cabin won’t heat the battery pack. Since many of us with Ds drive with range mode enabled all the time, to maximize the benefits of torque sleep, this means we need to remember to turn range mode off and on when arriving home and leaving, just so that we can preheat the pack and reduce the regen limit. Also because we will be enabling range mode again before we begin our drives, the regen limit will last for quite a while, since no energy will be wasted heating the pack.
For all these reasons an option to heat the battery pack would be very beneficial. We would use it most while on shore power, but I expect it would also be used at times while on battery power, by those that simply do not want to start a drive with regenerative braking limited. Naturally the option to preheat the traction pack would be most useful if it could be controlled remotely, via the iPhone and Android apps.
In the recently released version 7 of the firmware, Tesla introduced the Max Battery Power option, which heats the traction pack so that the car may perform at its very best, perhaps shaving a few tenths of a second off its 0-60 and quarter mile times. Providing a traction pack heating option to eliminate the regenerative braking limit would, in my opinion, most certainly have broader appeal and be of more practical use. As evidence of this, I’d like to direct you to a poll that I started on the Tesla Motors Club forums shortly after writing you about this issue in February. That poll is available here:
http://www.teslamotorsclub.com/show...-you-use-battery-heating-if-it-were-available
You will see that as of today, 186 people responded to say that they would use battery preheating if it were available, and another 20 said that while they wouldn’t use it themselves, they recognize the need for it and believe Tesla should make it available for those owners that want it. Only ten people responded to say they didn’t see a need for it at all. Of the 186 people who said they would use battery preheating if it were available, 122 of these people said they would use it very often.
It is clear that Tesla owners want this feature. Please give it to us in version 7.1
Thanks very much.

As I said in the post above this one, I have now written to [email protected], with the suggestion for battery heating, and directing them to this poll.
There's another thread where all sorts of suggestions for improvements for version 7.1 are being gathered and voted on, and last night one of the posters involved in that thread posted the following:
The battery pre-heating suggestion is already the second most popular suggestion in the battery category, but if the information is really likely to make it to someone at Tesla who can make a difference, I think the more people who have demonstrated interest in battery pre-heating, the better. So I'd suggest that if you'd like to see this feature implemented, you take a moment, click on the link below, and cast your vote for it. Thanks!

This is the thread that explains the voting process:
