pharma5 From Elon's comments at TESLive and Twitter: "We are going to do something special for Roadster owners next year. I can�t say what that is, but I can say that it will be pretty cool."
As we enter 2014, what do you think it is?
EDIT: Please vote from the options above - thanks to all for participating!�
Dec 29, 2013
ecarfan I hope it is #3. But only some Tesla employees know for sure...�
Dec 29, 2013
bonnie #1, the 80amp pilot signal bug, is already fixed...�
Dec 29, 2013
pharma5 Absolutely, as reported here on TMC. :smile:
But do you think that will be all?�
Dec 29, 2013
bonnie I don't think that's it, no. I hope not! That wouldn't be exciting or cool or special. That would only fall under the category of 'long time coming'.
�
Dec 30, 2013
hcsharp I didn't vote. The 80A pilot bug has already been fixed and it's not 2014 yet. I can't vote for the adapter choices because it would mean all my hard work would go down the drain unless they do a crappy job like they did with the J1772 adapter. I think there will be a motor upgrade but that will also require a PEM upgrade and it won't let me vote for both. New brakes are a possibility but won't be the only thing. Improved pack with newer cells is a possibility especially if they offer a motor/PEM upgrade. I can't vote for "something else entirely" because I think the real answer is a combination of more than one item and not entirely something else.
I'm almost worried that it will, in fact, be 'pretty cool' because we have 2 kids in college and probably can't afford it.:crying:�
Dec 30, 2013
772 New battery back that can use superchargers!�
Dec 30, 2013
pharma5 Apologies HC, feel like I bungled including an option for "Some combo of PEM, motor, and/or battery pack upgrade".:redface:
Mods, is there any way you or I can edit that option in as next-to-last choice listed?
Absent a tweak to the poll options, I'd recommend voting for whichever item you think would be the primary driving force or most prominent item for such an upgrade. (I'd also note the poll is asking what we think it will be vs. what we want, although people can and will certainly vote however they want.:wink
For the adapter choices, in my head I like to consider the possibility that the design could still be sourced/licensed from you... the poll does not limit where it comes from...�
Dec 30, 2013
Vger THAT is my fervent wish, although almost certainly, it will require a new pack, new PEM, new MS-style inlet. Seems too good to be true (and probably too expensive to justify, as Henry fears above)!�
Dec 30, 2013
ChadS Yeah, I'm pretty darn confident that Supercharger capability isn't on the table. Too much has to change. Too expensive for so few cars.
My biggest hope is for an OPTION to buy a future battery pack (no need to make it now!) at far lower prices. That should help with Roadster resale values AND give Model S buyers more confidence.�
Dec 30, 2013
ggr I think it will be an announcement that there will be something cool for Roadster Owners in 2015! ;-)�
Dec 30, 2013
adiggs I think that ChadS has the right way of valuing what gets done for Roadster owners. It's not how many of the widget can be sold to Roadster owners - it's what it says to the next generation of owners about how their car can evolve later in time. We can wait several years for the initial Model S fleet to age, and then come up with something that seems straightforward like a battery upgrade, and just hope that it comes along, and learn THEN how upgradable these early Model S's are. We can all think that it's straightforward and easy to upgrade the Model S's, and I think we can agree that on the surface, it should be easier than something like that would be for the Roadster.
But if Tesla steps up in 2014 with something of that scale for the current Roadsters, the ancillary goodwill across the entire Tesla owner community will be huge. Like move-the-stock-price huge.
I'm voting battery - use the current battery box for a Roadster and "fill" it with Model S chemistry batteries. There will be firmware updates required I'm sure, but the change in chemistry takes the roadster from ~50 to 80 kW sized battery. Do that, and now its running around out there in the wild for everybody to see - it's not just theory, it's real. (Crazy notion that the Roadster battery has almost as many 18650 cells as the Model S85).
That's what would be exciting and cool to me. A new brake option - not exciting or cool.
What I really want to see is the combo talked about by others - updated battery chemistry, liquid cooling for the PEM, maybe liquid cooling for the motor, DC hardware bypass, Model S style plug, firmware that keeps everything happy, and Supercharger access. That would be a technology game-changer, not for what it does for the Roadster owners (all 2500ish of us), but what it says can be done for the Model S. I also know that it won't be easy and it won't be cheap.
The straight battery chemistry swap, which also won't be cheap, would still fall into the exciting and cool. Even if the performance doesn't change, charging to ~170*1.6 = 272 Ideal Miles for a standard charge each day; that'd be cool.�
Dec 30, 2013
Doug_G Upgraded battery pack would be my strong preference. However I expect nothing.�
Dec 30, 2013
Tesla 940 I read/seen Tesla's announcements and "confirmed" rumors for years regarding the Roadster and the Model S. I've rarely been "excited" - rather, I've been disappointed maybe because I had my hope up too high (if that is possible). Therefore from my perspective I doubt I will find the announcement to be "exciting". As for the battery - they have to do something and since the original batteries are no longer available using the Model S cells or even the next generation is simply something they HAVE TO DO. Of course Tesla could use this as their "exciting" announcement. Excitement is in the eyes of the beholder!�
Dec 31, 2013
Sparrow Upgraded battery pack and the option to use the old pack as a battery backup or UPS for your house.�
Dec 31, 2013
adiggs Ok Sparrow - you're right, the ability to reuse the old battery as a house UPS - THAT would be cool. I'm already thinking about how to pull something like that off at my house, and ~50 kWh worth of battery would provide a big assist. Very nice.�
Dec 31, 2013
bonnie Okay, now we're talking. At one point I'd talked to someone at Tesla about this. I'd LOVE to recycle my own battery pack into backup power for my solar system when it's time to replace my battery. What a great story to be able to tell.
And if that replaced battery just happened to offer greater range, BONUS!�
Dec 31, 2013
dsm363 It's fixed but was told it still hasn't rolled out yet. Should be soon though.�
Dec 31, 2013
dsm363 A 300 mile highway range pack should be possible and would be awesome.
Adding HPCs to Superchargers would be nice as well. Don't expect either though.�
Jan 1, 2014
Marius Indeed, Tesla will not develop all kind of features for 2500 Roadsters.
They will only develop something that helps sales for model S and future models. So only replacing existing battery cells with Model S cells brings an extension of range of about 125 miles. It seems to me it can easily be done with a small benefit for Tesla at a reasonable price.
Big message will be then: Buy a Model S because in 5 years time you will be able to make a 500 miles range upgrade as Tesla shows with Roadster upgrade.
Supercharging capabilities for Roadster is simply from marketing point of view not interesting.�
Jan 1, 2014
bonnie So to be clear: The majority of Roadster owners are well aware that Supercharging capabilities for the Roadster is economically challenging and most are not asking for that.
What most are asking for is simply a 70amp HPC at the Supercharging locations where we can charge our Roadsters.
I want to be clear on this because I see this getting confused from investor meeting Q&A to press questions to here on the forum.�
Jan 1, 2014
Johann Koeber Exactly. This would really help.�
Jan 1, 2014
Raffy.Roma How long does it take for a Roadster to get a standard charge with a 70amp HPC?�
Jan 1, 2014
djp It's just under four hours for a Range charge. On road trips I've found 2.5 hours is enough for a charging stop at 70A. I usually don't drive all the way to zero, so I'm already starting with a buffer, and I stop charging when the rate starts to taper.�
Jan 1, 2014
AudubonB Huh. And I thought "something special" for you Roadsterers would be to receive an external lift-inner&outer-chair for ease of cockpit entry and exit.....�
Jan 1, 2014
Doug_G About 3.5 hours, depending on source voltage and whether you're going for the last couple of percent (like the Model S it slows down). Going 0 to full is probably almost 4 hours, but you'd probably only bother with a Range charge overnight.
One advantage of the Roadster compared to the Model S without Supercharging is that you effectively charge faster. Being much smaller the car takes less power so you get more miles per hour of charging at the same power.�
Jan 1, 2014
Raffy.Roma Thank you for the information Doug. :smile:�
Jan 1, 2014
772 I totally disagree... from a user perspective, if I had to choose, I'd rather have a smaller capacity battery that can recharge faster (from a fairly large existing charging network of SCs) than a large, heavy battery that recharges slowly (from a fairly sparse charging network of HPCs). An upgrade to the charger is as good or better than a battery upgrade from a marketing standpoint IMO. 30 minutes for ~200 miles on a MS is nice... but a roadster, being more efficient in charge to miles, should do better than that. I don't disagree that an upgraded charger would likely need an upgrade to the battery chemistry as well. If Tesla can pull both of these off, it would make a great example of how the car can be upgraded to new technology as it develops. I know that it's something that some MS buyers (and owners) are concerned about (future upgrades and how the car will hold up).�
Jan 1, 2014
PokerBroker Supercharger technical documents currently include infrastructure to support 70 amp charging. I expect that this will be our surprise.�
Jan 1, 2014
bonnie That would make trip planning sooo much easier.�
Jan 1, 2014
wiztecy I had the new firmware flashed with the 80A fix in mid-dec.
- - - Updated - - -
I honestly don't believe the Roadster's pack will ever be used as a home powersource, reason being Tesla would need the original battery cage back. Without that you just have an energy source without any backbone and I'm sure Tesla will be keeping the old sheets as well.�
Jan 1, 2014
PokerBroker It might make more sense for them to install a Model S HPWC and simply have a MS to Roadster adapter available for sale. I would actually prefer this option to a Roadster specific 80 amp charger because it would open up the HPWC locations at Tesla galleries as well.�
Jan 1, 2014
bonnie While I'd like to be able to purchase the adapter, I'd rather have the Roadster-specific HPWC at the Supercharging sites. Otherwise the Model S/X/GenIII waiting for a slot would plug into the 70amp and charge there while waiting & the Roadster would never have a chance.�
Jan 1, 2014
drees Reference? Have you seen permit plans referencing them?�
Jan 1, 2014
Marius From user perspective I can agree with you but from the perspective of Tesla it is the best message to convince potential buyers of the Model S that range is not an issue anymore with battery upgrades.
Another thing you need to keep in mind is the not realistic range that Tesla claims for the Roadster. In Europe max speed on motorway is 130 km per hour which makes the real range 250km. I have done 125.000 km now and lost already more than 10% range so my practical range is about 200km. In 2 years time it will be reduced to a level that for sure I need an upgrade to keep on with electrical driving.
For replacing the battery Tesla will put something back in the car with the same weight so it does not change the telemetrie of the car. And this is the most simple way to do something for the Roadster owners.
As for the HPC charging I completely agree with you. It will cost close to nothing to put on every SC a 70A HPC charger with a Roadster connector. This would definitely be a big step forward, but the issue of degradation of the pack and the possible replacement without major changes to the Roadster brings me to the conclusion that it will be an upgrade to 80kW pack most likely.�
Jan 1, 2014
Doug_G Wow, an 80 kwh pack in the Roadster would let me do most of my longer trips without having to stop and recharge. That would be awesome.�
Jan 1, 2014
PokerBroker While an 80kwh pack is intriguing, I certainly wouldn't be shelling out $40k for it and they won't be making it free or as a loss leader.�
Jan 1, 2014
thefortunes The plans for the Madison, WI SpC included them.
However it doesn't make sense to go BACK to the SpC locations and do that work after the fact, so I doubt that will happen.
We can certainly hope, though.�
Jan 1, 2014
bonnie I'd be happy about this, since I'm one of the *foolish* ones who bought the battery replacement option.�
Jan 1, 2014
pharma5 Absent something new in the battery area, I'd say my own "$40k" is currently waiting on adding a Gen III that will hopefully have longer range and/or supercharging since my Roadster cannot get it yet. (Ok, better make that "$50k":wink
But I don't know that an 80kwh Roadster pack has to be $40k out of pocket for the customer, e.g., if you are trading in an otherwise-working 55kwh pack that passes all the service tests. Maybe it's $25-30k (???) with a trade-in, which gives Tesla a more affordable refurb pack for other owners. All hypothetical.
As bonnie said there are owners who prepaid for a replacement pack at time of purchase, modeled on ~7 year timeframe. I'd certainly want a new pack if I prepaid for it (unless the agreement said otherwise)!
I've said before that the positive PR of having the Roadster range jump would be priceless on the perception side (at 80 kwh, that's ~276 ideal miles std and ~350 range). Even at $40k a few owners would get it and show it. Put a couple of those in loaner Roadsters, akin to showing the Model S P85's, or in the CPO inventory. Allow the press to drive. Over 25,000 Model S owners then look forward to potential upgrade to ~400 mile pack, circa end of warranty. Many more non-owners decide the range issue is dead. Etc.:biggrin:
- - - Updated - - -
I should add that I don't currently expect the surprise to be a pack upgrade - the buzz for upgrades has been muted enough over the past year+ that it would genuinely be a surprise to me (albeit a very welcome one).
My very cloudy crystal ball says it's option 3 to remove the pilot signal issue and ultimately allow Roadsters to connect and 70A charge at all the same locations that Model S can charge. Applies both to certain J1772's as well as any Tesla-branded location. It would help bring the 'network' factor back to Roadsters, which is a big part of the value prop in the rest of the brand.�
Jan 1, 2014
drees Link to permit plans in the first post of this thread: Madison, WI Supercharger
I've scoured them, and can't find any reference to HPWCs - only 6 SC pedestals with possible plans for 2 more. What did I miss?�
Jan 1, 2014
ibcs I was looking at page 17 showing the spare 60 Amp 3 phase circuit. I was hoping that would be utilized for roadster charging. Apparently, I'm reading the diagram incorrectly.�
Jan 1, 2014
vfx Amen to Boonies's post!
We have been on this since day one. Literally. At the Supercharger Launch Event we hit all the accessible Tesla employees with this request. Engineers seemed optimistic (but mostly because they could see it a possible) and higher ups were crestfallen. They were so excited about the SC news when we hit them with the "What about charging our Roadster's on the side?" question it really took the excitement out of the room. We spent all night trying to get and answer on it. Since then how many Superchargers have been built? Would it have been more than $1K per location to have done it? The idea seems to have slipped into darkness.�
Jan 1, 2014
asgard I doubt the "cool" thing for 2014 is a battery pack upgrade. Not enough Roadsters have experienced degradation that necessitates an upgrade.
Longer drive distances can be achieved by the 80A fix and the ability to charge at SC stations.�
Jan 1, 2014
pharma5 All Tesla cars should be made "chargeable" at all Tesla sites. It's a brand thing.
Very odd to say I can 30A charge at nearly any Nissan dealer nearby but not Tesla's own SC network.�
Jan 2, 2014
drees Yeah, unless they are going to install a step-down transformer there (which I suppose is possible), that 60A circuit is 480/277V, not going to work for L2 charging.�
Jan 2, 2014
dhrivnak Love that and it is very sad when you put it that way. It would have been quite easy to install a 70 amp HPC or an 80 amp HPWC at each SuperCharger site.�
Jan 3, 2014
Raffy.Roma + 1�
Jan 3, 2014
AltPowr Would love to see some of the above ideas happen, but could the "pretty cool" thing just be the Roadster showing up in the Tesla mobile app along with the Model S?�
Jan 3, 2014
sethr I, too, would like to have charging at Superchargers, but more practical for all of us would be a liquid cooled PEM, or improved brakes. But my guess is that it will be something else, and probably something relatively inexpensive for both Tesla and owners... such as converting the Roadster to keyless ignition, possibly with a fob that shows some data such as SOC, charging status, maybe a locator function for parking lots (when every other car is hiding the Roadster!) Of course, there would have to be an accompanying (vast) betterment of fob range... Or maybe it's something we haven't even guessed at; Elon is a pretty creative guy.�
Jan 3, 2014
bart513 All this talk about what we would like to see but does anyone know when the announcement will be???�
Jan 3, 2014
djp I don't think Tesla themselves know what the "something cool" will be, let alone the announcement date!
Keep in mind this started as an off-the-cuff tweet from Elon after he was pestered by a Roadster owner on Twitter. I'm keeping my expectations low. :smile:
�
Jan 3, 2014
ItsNotAboutTheMoney When he mentioned it, Elon sort of played it down a bit, and has commented that he doesn't really see the Roadster as a long-trip car, so I don't think it'd be Supercharging capability.
But it's still a good business outcome to drop legacy technology, and it would be good PR to help Roadster owners with charging so:
- allow Roadster owners to use Model S HPC and fix charging bug
- plus Tesla donates a "destination HPC" for every Roadster owner: contact each owner and ask where they would like the charger to be. Tesla will try to get the destination to accept the free charger.�
Jan 3, 2014
pharma5 It could. Have to admit I thought about having it as an option in the poll, but with those rumors going so far back (and both Tattler and OVMS out there the whole time) it really seemed unlikely. But not impossible.
- - - Updated - - -
Definitely the reason for the last option.

Have seen no info on timing whatsoever. If anyone has a lead please chime in...

That's a cool wrinkle I hadn't seen before. Maybe free hardware and complementary install (Solarcity or other)...who could say no to that?�
Jan 4, 2014
JohnGarziglia For my purposes, and I suspect a lot of other Roadster owners, a very good thing that could be done would be to encourage or sponsor the addition of 70 or 80 amp. charging stations at decent non-metro-city hotels and restaurants. This would also help Model S owners. Some sort of arrangement with a Hampton Inn, or Holiday Inn Express, or similar chain, in which the charging stations are ideally located in valet or bellhop controlled areas (to keep from being ICE'd), and are reserve-able in advance by any Tesla driver.�
Jan 4, 2014
bonnie Sent a tweet to BoredElonMusk to get his take on this. He might have some good ideas!�
Jan 4, 2014
dsm363 Thanks. I called my service center last week and they said they'd look into it but didn't think it was out. Will call again.�
Jan 4, 2014
djp Ha - that's great!
I'm sure this is how it's playing out at Tesla:
Elon: hey JB, a couple of months ago I was bored on twitter and promised the Roadster owners something cool. Can you whip something up?
JB: <facepalm> Sure thing Elon, I'll get right on that..
<checks TMC forum to see if we've come up with anything easy and cheap>�
Jan 4, 2014
WarpedOne I'd say all proposed ideas are doable.
When roadster was the star the story was that when the time comes to replace the batteries there will be cheaper and better batteries available.
Tesla also offered a pay-in-advance-for-a-new-battery-in-7-years plan. Those 7 years will start expiring in 2014 - 2015 time frame hence Tesla is obliged to deliver the product customers have already payed for - a new roadster battery.
It is not a question of if - they have to deliver new batteries because they have already been payed for with a delivery date.
They may choose to use same cells as in 2008 that are half the price now and collect good margins. Such doing would certainly end in negative publicity - what happened to the story of ever better batteries?
I'd bet they will offer a bit larger and a bit lighter pack - using a bit less cells. In this way customers will get a longer range as originally and the cost will be less than a 'full' pack. A bit less weight will also improve performance a bit.
Edit: Heck, they might pull a stunt and use 4000mAh cells. They might not have same power as 3400 cells, but I bet they have at least the power of 2400 cells used in roadster.
Anyone interested in 400 mile pack?�
Jan 4, 2014
PRJIM I do not thing it will be an improvement to the battery pack as this will be cost prohibitive. The price point will probably be <$25k and I could see it as being a passive cooling improvement to the motor and a LSD. The whole motor could be brought down relatively quickly and easily and replaced with a bolt in unit without that much work. Changing the pack takes much more time and effort and will require major testing for homologation.�
Jan 4, 2014
ItsNotAboutTheMoney Absoluteky, but that would be a general benefit. Specific cool needs a specific benefit.�
Jan 4, 2014
bart513 As one who recently purchased a new/refurbished battery:
1) There was no change in the cost of the battery
2) I was specifically told that they were not working on a new/better battery for the Roadster at this time :crying:�
Jan 4, 2014
pharma5 ROFLMAO. If that were true, this poll may be helpful :wink:... as of this typing, the largest subset of the self-selected TMC members that answered, 27 of 71 (38%) are think it's some type of battery pack upgrade. This response has been surging the last few days to pull ahead of option 3 (bug fix, charging adapter, HPWC at superchargers).
- - - Updated - - -
I remember that - still possible it's something else entirely for this year.
What else could it be? Maybe an offer for straight-up trade-in for Model S P85+?!?�
Jan 4, 2014
adiggs
I wonder how many Roadster owners would take up Tesla on a generous offer like that (trade in your Roadster for a Model S!)? It's taken me less than 10s of thinking about it to realize that Tesla could make me that offer today and I wouldn't take it. I got mine used, and have only had it for 10ish months. Maybe I'll feel differently in a few years, but today, it not even much of a thought.
From others comments in this thread, of the various ideas tossed about, I have also come to realize that some sort of 70A charging option for Roadsters at the SC stations - it wouldn't be AS exciting, but that WOULD qualify as cool, useful, and interesting to me. Like others, I wouldn't make much use of those chargers, but I would make some use of them, and that would create the desired effect - of expanding the effective range of where I'll go in the Roadster.�
Jan 5, 2014
TEG Perhaps when he said "do something cool", he meant that literally... My vote would be improved PEM and/or motor cooling...
�
Jan 5, 2014
ELMIV �
Jan 5, 2014
Pantera Dude What would the improved cooling accomplish? Additional laps on the race track? Longer life of the PEM and motor? Any performance increase?�
Jan 5, 2014
TEG I would think additional track laps at full performance and when driving really hard on hot days.�
Jan 5, 2014
djp I was excited about the liquid cooled PEM and motor when the rumors first came out, but less so now after seeing that the Model S is actually more limited on the track than the Roadster, despite having liquid cooling. It's not easy to cool the rotor, and we'd probably need a significant HVAC upgrade in addition to the new plumbing.
Elon's tweet was in the context of recognizing early adopters for their support. I'm now thinking the "something cool" might be a factory party to thank the early owners, or small regional events. It might not be an upgrade for the cars at all.�
Jan 5, 2014
bonnie When Tesla decides to throw a party, a real party ... well, there's nothing like it. I was thinking it might also be something like a party with a large plaque with the names of the original owners who got them to where they are today. Be part of history. Something like that.
But I'd really like that upgraded battery, if anyone is reading this thread. And I'll even help pay for it. Just letting you know, whoever you might be.�
Jan 5, 2014
pharma5 The TESLive statement was broader and more explicit, per first post on this thread - it's something cool for Roadster owners. See 14:07, in response to direct question on the topic:http://www.youtube.com/watch?v=8n-xsEjq7pk.
(The wine was only starting to flow, and the resource caveats were: getting through Euro intro of Model S, rollout of Superchargers, and Model X design & eng).
By all means, though, throw a party for the earliest early adopters!:biggrin:�
Jan 6, 2014
smorgasbord Now's not the time to lock in the next-gen battery pack for Roadster. We should skip the Model S/X generation and go with the Model E batteries. Almost all of us can hold out that long I believe.
What is "something cool?" Well, it's not "awesome!" and it's not "meh." So, it won't be 0-60 in under 3 seconds (which would be awesome!) and it's not a Model S to Roadster charging adapter, nor Roadster HPC's at Supercharger sites (which would be "meh, why did it take them so long?").
As others have pointed out, if you're going to do something that you could sell to maybe 500-1000 owners at best and didn't want to lose a ton of money in the process, what would you do?�
Jan 6, 2014
pharma5 Most early votes in the other poll agree with you - interested in a few years, or when something goes wrong, or prepaid pack replacement is "due" (2015ish?).
Maybe it's not even a "sell"...more like a gift?�
Jan 7, 2014
Alan Perhaps after a few years of collecting data they feel confident they can push the limits of power / torque that can be delivered without damage? How about a software upgrade that takes the standard car to the sports level of performance and drops the 0 to 60 of the sports down to say 3.4 seconds.
If that was possible it would be cool and cost little to implement. If given free as a thank you it would qualify as awesome and generate some good PR�
Jan 8, 2014
pharma5 Don't know if it can be done, but that's a pretty cool thought to get a better car by "flipping a switch". :smile:
What else might fit into that category?�
Jan 9, 2014
sethr Here's a possibility; add functions like the charging level control of the Model S to the Roadster's VDS. I'd be keeping my charging level at 50% or less, since I have yet to take a trip over 50 miles total.�
Jan 9, 2014
Fluke Although more limited than the options on the Model S, the roadster does have a storage mode that allows keeping the charge level at 50% already.�
Jan 9, 2014
djp Storage mode is 25%. I find it's not hard to keep the SOC between 35% - 50% by charging once a week. A slider would be nice though.�
Jan 9, 2014
Doug_G That's one issue I have with the Roadster's storage mode. I'd rather it keep the car closer to 50%. I think that 20% is kinda low. I'd like to have more of a buffer against an extended power outage, etc.�
Jan 9, 2014
thefortunes I don't use it (I just do a standard charge every night since I drive 110-120 miles every day), but the latest version of the OVMS firmware allows you to automatically charge to any percentage if you enable ACC.�
Jan 10, 2014
Morlaixjam As a Roadster and a Model S owner in Europe (France).
I will really appreciate to have the possibility to control my roadster like the Model S via an Android or Apple cell phone application.
To have standard socket Type 2 (car side) to be able to charge at 70A with an AC 22kW charging station even using one phase (100 km per hours).
I think the nicer gift Tesla Motors could offer to the Roadster is to be able to update for some $ the PEM for accepting DC current on SuperCharger.
Hope, hope can become reality�
Jan 10, 2014
patp Bonjour du Quebec.
Great suggestions. As for controlling your Roadster from your mobile phone, there's a great inexpensive third party solution that works well:
OVMS Module for 2.x Tesla Roadsters | Open Vehicles�

wycolo Maybe not this go-around, but whenever the battery technology significantly improves, Tesla should build a replacement pack that is Supercharger capable (to the same extent the MS battery pack contains SC enabling devices). Then develop an SC module and charge port to be installed with the new pack. SC charge rate will be less than an MS of course, but the R has a smaller battery.

Denver Service showed me a new R battery in crate and they said it could be installed almost as quick as an MS. Why would replacement components need homologation??
Allowing Roadster access to SCs could be addressed in this fashion.

I have seen a Roadster pack being installed, it takes several hours to install. Unless something has changed in the past 18 mos or so with regards to the method used to change the Roadster battery it is still a labor intensive process. By 2016 chances are there will be a new Roadster available that will be technically superior to our Roadster in almost every way. I do not think Tesla would invest a tidy of sum of money improving our "old tech" Roadsters.�

PokerBroker I think 2019/2020 is a more realistic date for a new Roadster. With the Model E slated for 2017 they will have their hands very full.�

Doug_G At Teslive Elon stated quite emphatically that Supercharging is not in the cards for Roadsters.�

PRJIM The more I think about this the more I am convinced that Tesla will be offering lower capacity packs. As Roadsters come out of warranty there will be a need for a cheaper alternative to the 53kwh pack. I know a few people that have had sheets replaced out of warranty and the costs were about 30% of what a new pack would cost. If a warranted 30kwh pack was available, I would imagine the take rate would be higher compared to an equal cost repair of the 53kwh pack. A lot of Roadster owners are Model S owners and mainly use their Roadster as a weekend fun car. I am not sure if this is relevant to the cool tweet but it would make sense for Tesla to offer a lower cost alternative to the 53kwh pack.�

hcsharp I might have to disagree with that. I don't know a single person who would buy a lower capacity pack. It would also suffer from lower performance, shorter life and slower charge rates. It would take more engineering and development time for Tesla than a larger capacity pack so I'd be surprised if they could even offer it for a lower price. Remember the 40kWh pack in the Model S? Almost nobody ordered it. It was costing Tesla more to make it than a 60kWh pack.�

Doug_G I would also have to disagree. No one is going to want to reduce the capability of the vehicle. I sure wouldn't.�

dsm363 I would definitely not want a smaller pack. Even though it is a weekend car for many it would eliminate any road trips as you can't supercharge it. Bigger pack is needed actually.�

ChadS Now that I've got the Model S for road trips, I would definitely buy a cheaper, smaller pack for the Roadster. I would assume between fewer cells and more power-dense ones, they could keep the performance the same (though heck, I'd probably buy it even if performance drops a little).
However, the problem with that is (as noted here) that not everybody would want it - and they sure they heck aren't going to make a variety of replacements packs. If they make one at all (I'd rather they just sell a future replacement at reduced cost now; actual pack to be delivered later), I would think it would be a compromise to give everybody a little of something: a little cheaper, a little lighter, a little more range, a little more power.�

As WarpedOne said a bit upthread, they could offer a somewhat larger and somewhat lighter pack - so tasting great and less filling. Between more capacity and less weight the range would be better (maybe a Model S challenging 300 miles?). I don't know what limits on performance there are outside of the battery - the PEM and motor would need to be able to handle it. As a non-sport owner I hate to say it, but perhaps only the Sport model could really get the performance advantage a more powerful battery would have?
But, this isn't what Elon has in mind for Roadster owners this year.�

WarpedOne Tesla Roadster uses 6831 cells, MS85 uses 7104 cells.
Roadster has 2000mAh (53kWh/6831) usable/cell, MS85 has ~2900mAh (77kWh/7104) usable per cell.
Transplantation of MS' cells into roadster battery pack should yield about 53 kWh * 2900/2000 = 77 kWh usable, improvement of 45%. This would result in ~350 EPA mile range.
How did elon got to 400? Elon-speak?
Not necessarily:
350 miles * 1,1 = 385 EPA miles
350 miles * 1,15 = 402 EPA miles�
