New Firmware V 4.3

New Firmware V 4.3

Just installed V4.3 with two new features:

- you can now set the time to start charging (Yea!)
- climate control adjusted to be a bit warmer on all settings

Thanks, Tesla!

gasnomo | 13 March 2013

wow, thanks for the update!

Alex K | 13 March 2013

The charging timer lets you specify a starting time and it runs until the car is charged. I posted something like this over at TMC:

I guess this is an OK initial attempt for a charging timer. In my case, I would like to set multiple date and time ranges to make use of seasonal TOU rates. For now, I'll have to reprogram the timer every season and set the start charge time for one of the daily off-peak times and hope that the charging finishes before on-peak starts.

I've been on the same TOU plan for 20 years. There are 2 seasons: there is one summer off-peak period and two winter off-peak periods. Weekends and some holidays are also off-peak. An interface that lets you specify date ranges and charging time ranges would be nice. I know it would get more complicated with multiple locations, but hey, it's only software.

gasnomo | 13 March 2013

just called Tesla, they claim its not out...are you part of the beta program?

Aleksandyr | 13 March 2013

we are all part of the BETA program!!

reitmanr | 13 March 2013

Great!
So if I am traveling (without my S) I can be sure charging happens during the lowest rates which for us is between 6pm and noon and all weekend.
Thank You!

gasnomo | 13 March 2013

Ha! but seriously, apparently there is a subset of owners who signed up to get releases early as part of a beta program...i don't think its a wide release yet. I was told by a rep on OE if the release was public, something would popup on the 17" display indicating a firmware update is available...

ScottM | 13 March 2013

I'm not aware of being on the beta program, but would join if offered! I've noticed that sometimes I get a new version earlier than most and sometimes later. I suspect they deliberately roll it out iniitally slowly so that if there's a bug they can fix it before it goes to the masses.

gasnomo | 13 March 2013

thanks for the clarification Scott..I hope to see it soon!

DouglasR | 13 March 2013

I think the beta program was for the app, not for car software updates.

David59 | 13 March 2013

With any luck the iPhone app will be updated soon to reflect the new scheduling feature as well. That will be awesome.

jbunn | 13 March 2013

Any feedback from those running 4.3 about vampires?

Rod and Barbara | 13 March 2013

v4.3 loaded in our S today. It also contains improved range projections in cold climates. Sleep mode is not fixed so there should be no improvement in vampire energy draw.

noel.smyth | 13 March 2013

I want to be able to schedule the finish charging time! this is great for having a nice warm battery when I leave for work on a cold day!

gasnomo | 13 March 2013

Is this automatic? do i have to do something to get the update?

Pungoteague_Dave | 13 March 2013

alex and noel: Seriously? Wa wa wa

cfriedberg: It is automatic. TM says they roll it out slowly over a period of weeks (I think 4.1 took over a month), because, like all new software, unanticipated isues and bugs can emerge no matter how much testing is done, and they want to catch things before the full rollout. There is also a bandwidth limitation because it it isn't just "sent out" - it is an interactive process between the car and TM, where TM's systems anayze car status, and the download process etc., so they cannot do all cars at once. Wireless phone carriers also roll out new software o/s updates on a similar long schedule for that reason.

You will receive onscreen notice after the update download is complete, oferring to install it at the next 2:00 AM, or immediately. You can make a choice and it will go through a long process of turning stuff on/off, flashing lights, rebooting, etc. I have not seen it happen on my car, but am told it can take an 20 minutes to an hour. MIne happened at 2:00 AM and was ready to go, with an onscreen success anouncement the next morning, with the customary release notes.

Alex K | 13 March 2013

@Pungoteague_Dave | MARCH 13, 2013: alex and noel: Seriously? Wa wa wa

Yes, Seriously! Just because they put a ribbon on a turd and called it a truffle, doesn't mean we have to eat it (old Greek saying - looses something in the translation).

From the release notes:

Scheduled Charging allows owners to take advantage of time-of-use rates by delaying charging to a time when electricity rates are more economical

All I'm saying is that electrical rates are not always economical the exact time every day and I wish there were a way to specify what those times are.

jat | 13 March 2013

@AlexK - the UI gets confusing if you want to be able to handle it in the car. For my app, I am using Google Calendar -- you can create whatever calendar entries you like saying when it is acceptable for the car to charge and what you want to charge to (ie, you can say charge to at least 50% no matter what time it is, then charge to full standard during these times, etc). That hides the complexity of how to do repeating events on particular days etc, but that is complicated to implement in the car's UI.

Alex K | 13 March 2013

@jat@jaet.org | MARCH 13, 2013: For my app, I am using Google Calendar

That sounds like a great idea! I guess you could also look at the current car location and make it location based. In my case, the 3G reception is spotty in my garage. The last update that it downloaded, I had parked at a restaurant. Hopefully the Tesla WiFi support will be forthcoming and useable with the REST API. If not, I'll have to install a cellular rebroadcaster.

shop | 13 March 2013

Yeah, I upgraded my wifi in the house to make sure I had good wifi signal in the garage for the tesla.

I think a simple car interface for time of day charging and then if people want more, you can use a web based program...

weeandthewads | 13 March 2013

The scheduled charge is going to be a good addition. I did notice one thing with the TM Supercharger. The green light bar is always on, so it appears that even though the timer will restrict the charge the charger itself is still drawing power all day long. Not sure how much, but at least enough to keep the light on. Does the Supercharger need a timer?

DouglasR | 13 March 2013

@rtesta

Do you mean the HPWC?

gasnomo | 13 March 2013

@shop. How does upgraded wifi help? Car is 3G, wifi hardware is t activated yet is it?

jat | 13 March 2013

@rtesta - any EVSE draws negligible current. I leave the LEAF J1772 EVSE and the Tesla Mobile Connector plugged in (I don't have the HPWC yet), and I can't measure the draw of either of them on the TED5000 monitoring my garage, and there really isn't anything else of note on there. I can see other 100mA loads, so the combined current has to be less than that.

noel.smyth | 13 March 2013

@P..._Dave - its just software..and the requirement is not even that complex...chill...

shop | 13 March 2013

@cfriedberg - I upgraded the wifi in anticipation of wifi functionality since I too have spotty 3G in my garage. You're right, the car can't use it yet.

bfranks273 | 13 March 2013

I got my install today. I'm a sig, maybe they rollout by delivery or vin order. And all I was doing before was setting an alarm to start charging so this is great for me. Saves me from forgetting. If you want to moderate the amps over time, or shut it off, you are still in manual mode. And the app does not yet seem to know much about it. It says starting to charge, Stop charge button, so its different, but not settable from the app.

Pungoteague_Dave | 13 March 2013

Alex, a cellular rebroadcaster (Verizon calls it the Wireless Network Extender) is well worth the money and effort.

Both of our homes are in marginal zones for Verizon and AT&T. Calls were constantly being dropped, and we had to go to a certain spot in the house for best reception, or sometimes any reception at all.

We use Verizon Wireless for all of our smartphones, so I tried the Verizon exetender, which they sell for $250. We have Verizon FIOS internet service at one house and Verizon DSL internet service at the other. The extenders work equally well at both houses, so internet speed in't critical, as our DSL service is a lot slower than the FIOS service.

The extender is literally a miniature cell phone tower inside the house, and we find that it provides maximum bars anywhere in the building.

eelton | 13 March 2013

Any idea whether the rain sensing wipers work better under 4.3? They're not great in 4.2.

dortor | 13 March 2013

from one of my previous EV cars had the following features for time of use charging - and I now consider them the minimum standard:

a) chargers visited were saved by GPS co-ordinates
b) scheduling was based on charger being used, not a global setting
c) you simply entered your rate plan from your electric bill and the car did the rest
d) you set a "time" to be finished by so that the car was always charged by #:## regardless of time of use charging - but the car would maximize the amount of time on the lowest rate

if Tesla does any less than these four criteria I will look forward to future updates so that they can match the feature set of other "lesser" EV cars.

dortor | 13 March 2013

screen shots from the other forums confirms location based charging…so tesla has covered 1 of the 3 minimum requirements for a full scheduled charging system (since a & b above are basically the same thing).

gregv64 | 13 March 2013

I'm sure they will continue to improve the feature, but any scheduled charging is better than none at all, right?

dortor | 13 March 2013

agree - scheduled charging is better than nothing - but we need to hold tesla to high standards for our own satisfaction and their on-going success.

Robert22 | 13 March 2013

Agree, best of breed means hardware AND software. That said, I'd rather have the basic functionality provided early with future enhancements, rather than waiting three more months for a fully featured update.

Brian H | 14 March 2013

Also, you appreciate the improvements more if they come out one spoonful at a time. >:)

gasnomo | 14 March 2013

thanks for the clarification @shop...me too, 3G sucks in my area.

Beaker | 14 March 2013

Why make things more complicated than they need to be?

Let's take PG&E in California as an example:
PG&E off peak summer:
M-F after 9:00pm - 10:00am
Weekedns after 8:00pm - 10:00am
Holidays

Winter:
M-F 8:00pm - 5:00pm
Weekends & holidays.

Overlap the off peak times and you discover that they overlap from 9:00pm to 10:00am all year. On a NEMA 14-50 outlet you can easily get a full 300 mile charge within that window.

So until PG&E redefines off peak a 9:30pm start works every day of the year.

Nice and simple.

Pungoteague_Dave | 14 March 2013

Beaker, +1!

just set for 9:30 PM and forget it. Except for someone who will say "but I want to set it to be ready when I want it ready because my Volt could do that."

With all the premutations of things people would likeeee to have for their one unique sitation, we could have TM chasing its tail for years. Give them a break.

To put this in perspective - how many software updates does Apple issue per year for the iPhone? Two or three, until it orphans them after a few years. Apple sells more iPhones EVERY DAY (about 250,000) than Tesla will sell vehicles in at least FIVE YEARS (assuming ramp-up, Apple actually sells more iphones every day than TM will sell cars in more than 10 years at the current production pace).

So Apple has a team of software developers putting out great products and updates for hundreds of millions of end users and amortizing/allocating their costs accordingly (Apple is currently selling over 25 million iPhone units alone per quarter). Yet we expect TM to keep our systems as technlogically up to date as Apple does, with fewer than 100,000 vehicles being delivered over the next few years, by TM's own estimate. I am not saying we shouldn't expect that, but the scale of work being done for so few beneficiaries is unprecedented in mass-production software development, except for bespoke control systems for things like manufacturing, power plants and airplanes, where the software can cost millions per installation.

I am amazed at what TM has been able to do with its software interface and control systems, for so little. A skeptic software engineer friend who drove my car said "what you have here is a million dollar product for a fraction of the value."

Short of supercar manufacturers with vehicles priced over $200K, every car major manufacturer can amortize its software costs across multiple platforms and models, with the lowest volume real car companies selling at least 100,000 cars per year (Porsche will sell 140,000 cars this year and shares technology with VW, adnd Jaguar/LandRover will sell over 300,000 cars), many times the volume that TM will achieve this year.

TikiMan | 14 March 2013

Uploading it now!

weeandthewads | 14 March 2013

Yes, the TM HPWC has a light that stays on, if you goto a TOU plan the connector burns electricity all day lon.

Beaker | 14 March 2013

I can see the argument of having a finish charging just before hh:mm, for those in cold climates.

I'm sure one of us programmers can crate an app to handle this case fairly easily though.

BYT | 14 March 2013

4.3 installed at 9am today with no issues at all to report.

gasnomo | 14 March 2013

still no update here :(

joepruitt | 14 March 2013

Just updated this morning. I came to the car with and it stated a 309 ideal range. Even though I know it's the same charge, seeing the range "over" 300 just gave me a warm fuzzy. That was until I realized that the update had set the charging to "max range" mode.

The only other side-effect I could see was that it turned on the radio to the Slacker Justin Bieber station that my daughter had turned on the night before - I couldn't hit stop fast enough...

The SW pace reminds me of the earlier days of Android phones. The overall feature set and robustness was not quite up to the other mobile operating systems available but the pace of updates simply ran away with the innovation as if other platforms were standing still.

In this case you have a large, expensive mobile computer that is committed to constant improvement. This is many many times more valuable than the day 1 feature set in my opinion. When you spend this much on a car it is nice to know that you are in for major enhancements during its lifetime rather than the usual feeling of falling further behind each day, starting with the day you drive off the lot.

I think it is short sighted to hyper-focus on today's feature set against other solutions that are not being enhanced at this pace.

JZ13 | 14 March 2013

Has anyone with a higher vin (4,000+) received the upgrade yet? I'm curious if there is a pattern to the software rollouts.

TikiMan | 14 March 2013

FYI... Finished uploading, and noticed that my doors would no longer detract and lock after exiting / walking away, or pushing the fob.

Called Tesla Customer Service, and they said to do a full reboot, which solved the problem ASAP.

EcLectric | 14 March 2013

I saw a later TikiMan post, and the fix was only temporary. I would wait before upgrading if I saw the upgrade message.

skulleyb | 14 March 2013

@ rtesta@pacbell.net
I have the HPWC and that light is an LED and i watched my TOU meter and it doesn't even register movement when only the light is on.

alfafoxtrot1 | 15 March 2013

24 hours after pick up, I took a short trip in my 60kwh, roughly 80 miles from home. I arrived with 80 miles of range left (didnt go directly there) and plugged into the Chargepoint level 1 (not sure why they go to the trouble to install a charging station and don't go level 2?!). 4 hours later, range still shows 80 miles despite my Tesla and Chargepoint app showing 12 amps flowing. I have 2 days here but still feeling the anxiety. Calls to Chargepoint and Tesla lead to weather as the culprit. I didnt think 40 degrees counted for the cold weather issues. Anyway, Tesla's answer was to push 4.3 to me. End result, range steadily increasing at about 3mi/hr. i gather that I was indeed charging before and the display was simply off, but I was definitely feeling the anxiety. I didn't want to be nominated for a Broder award by departing with insufficient range showing and a hope it would magically improve. So, while most of the comments on 4.3 focus on timed charging, the improvement in cold weather applications is indeed important and appears to be working.
