tomsax Tesla has a fix for the Roadster 80A charging bug.
This will enable Roadsters to charge from unmodified Clipper Creek CS-100 charging stations.
The Roadster is still limited to 70A charging, as increasing that limit would presumably require hardware upgrades.
Update January 16, 2014 The firmware update is now available. Yesterday, I got the update and a car wash at no charge for our out-of-warranty v1.5 Roadster.
The details from Danny at the Seattle service center are:
v1.5 firmware is 3.6.12 and is just the 80A fix.
v2.x firmware is 4.6.8 which fixes the 80A bug and allows shifting from drive to reverse at up to 5 mph
dsm363 confirmed the 80A fix on a 2.x Roadster. I've confirmed the 80A fix on a v1.5 Roadster.�
Nov 7, 2013
Jackyche does it allow higher than 80amp charges or just able to handshake with high amperage charges?�
Nov 7, 2013
dsm363 Awesome news!�
Nov 7, 2013
Curt Great to hear - keep us posted.�
Nov 7, 2013
bonnie As soon as I get the fix, I'll go check it out at the same place where it was originally discovered.�
Nov 7, 2013
Doug_G That's great news! I could definitely use this.�
Nov 7, 2013
Tesla 940 Thanks for your efforts.
Don�
Nov 7, 2013
wiztecy Is there a map of where the CS-100's are installed? For me in the Bay Area? Nice to see there's still a Tesla lifeline with the Roadster.�
Nov 7, 2013
hcsharp jeez I spent a ton of time developing a solution for this over the last several months and was about to start offering it to people. That's OK, fixing the bug is a better solution. My first prototype that I had at TESLIVE in July didn't meet code apparently (I had it reviewed by an EE) so I developed another solution and just barely tested it. Well I knew it was a risk and I still have the adapter without any electronics in it - the Model S to Roadster adapter.
- - - Updated - - -
The best news here is that we will soon be able to charge from the ubiquitous Model S HPWCs.�
Nov 7, 2013
vfx Wheee! Thanks Tesla! (and Tom
�
Nov 8, 2013
VolkerP While I agree that this is good news, it is barely the minimum Tesla could do to support the Roadster.�
Nov 8, 2013
Doug_G Hard to argue. But prior to this they weren't achieving that minimum, so it's progress.�
Nov 8, 2013
Botbldr45 hcsharp: We are all very grateful for your research and development of the "Can" adapter and invaluable technique information on soundproofing and insulating the cockpit of the roadster. Please keep me on the list for the MS to Roadster adapter.
:biggrin:�
Nov 8, 2013
dsm363 Tom had been working on this for years I think.
I think with Jerome taking over that made a big difference. Thanks Tom for working on this and thanks to Jerome for finally fixing this bug.�
Nov 8, 2013
tomsax I haven't tested it, but I'm quite certain it just solves the problem reading the pilot signal to allow 70A charging at 80A-capable stations.
- - - Updated - - -
I didn't get interested in this until a few months ago when I found out that Sun Country Highway had installed 145 CS-90s rather than 80A CS-100s because of the Roadster bug. My role was just informing Tesla that this Roadster bug was having an impact on the Model S community.
Thanks to Bonnie for discovering and documenting this problem years ago. Thanks to her work, Tesla was well aware of the issue and had put enough thought into it that they were able to get the fix out pretty quickly when it became a bigger issue.
It sounds like Scott451 (now a Tesla employee) may have played a role in this as well. Thanks to everyone at Tesla who still remembers and supports the Roadster community.�
Nov 8, 2013
Doug_G FYI Sun Country Highway has now switched over to 80A stations, and won't be stocking 70A anymore, so the timing on this is perfect.
I checked with our service center and the update has not been released yet, but they promised to install it for me once it is available.�
Nov 8, 2013
bonnie Yep, it's my understanding that Scott451 had a hand in fixing this problem. As soon as I get this fix, I'll take it back to the original 'scene of the crime' and go thru the original steps that first uncovered the problem.
I'll give a quick call to my local service center and let them know I'd like the update as soon as it is available.
Thank you for alerting us all that it is soon available. And thank you for keeping this at the top of the queue with Tesla. I can't imagine how frustrated I'd be to find an 80amp J1772 in the wild and realize I couldn't charge!�
Nov 8, 2013
jory is the fix just a firmware update or does it involve hardware changes? my roadster is going in for minor service (GPS stopped working after annual service a few weeks ago) in a couple weeks so i'll ask about getting it then. thanks!�
Nov 8, 2013
dsm363 Just a firmware fix.�
Nov 8, 2013
strider Are you working on a ModelS-Roadster adapter?�
Nov 8, 2013
mknox I've got two CS-100's on order. Sun Country told me they have newer firmware that deals with the Roadster bug, and apparently one other EV model that also had problems with these larger charging stations. Sounds like the issue is being addressed from both ends...�
Nov 8, 2013
djp Hopefully they don't cross paths and break each other!�
Nov 8, 2013
mknox Seriously! I originally planned on CS-90's (out of respect for Roadster owners) until Sun Country told me of their fix.�
Nov 8, 2013
Doug_G The new CS-100 firmware is, from what I've heard, able to reduce the power the station reports to 90A through the push buttons on the front panel. I believe it's the Leaf that also has the 80A problem.�
Nov 8, 2013
hcsharp I had a prototype at TESLIVE. That's the best part of getting this bug fixed. There are way more Model S HPWC out there than there are 75 or 80A J1772 stations.
It contained electronics to overcome the Roadster bug. Then I discovered a small NEC compliance issue after discussing the design with a couple of EEs so I had to start over on the electronics. I was just about to start testing the new design - only to have Tesla eliminate the problem! It still needs electronics, but now it's very simple and I plan to send a couple of them out for testing later next week.�
Nov 8, 2013
brianman I'd really like to see if Roadster HPC->ModelSAdapter->RoadsterAdapter->ModelSAdapter->Model S works.�
Nov 8, 2013
hcsharp I tried that but the Model S got confused and started wanting to be a Roadster. Every day it began looking more and more like the Roadster. I really got worried one day when I opened the door and saw that the 17" touch screen had shrunk down to about 4", so I stopped the experiment. :tongue:
I did make a Roadster HPC to J1772 connector but it was a 1-off project and I have no plans to make any more.�
Nov 9, 2013
TonyWilliams The last CS-90 in stock at Clipper Creek was purchased by a Rav4 EV owner just a few weeks ago.�
Nov 9, 2013
pharma5 80A fix is very cool news. I wonder if this spoils our 'something cool' surprise for 2014?
Feels like a fix to connect/charge on Model S systems...�
Nov 9, 2013
djp Ha - I'm going to be very disappointed if the "something cool" is a Model S HPWC to Roadster adapter.�
Nov 9, 2013
DrComputer Cool. I have an old Tesla HPC that I converted to a J1772 end instead of the Roadster connector. I purchased the cable with the J1772 connector directly from Clipper Creek. At the time they offered to also send me the programmer so I could increase the output of the HPC from 70A to 75A but said that my Roadster wouldn't charge if I did that. I assume that I can now do this if I get the firmware update on my Roadster. This will now allow me to charge the S at 75A while the Roadster would still be limited to 70A?�
Nov 9, 2013
dsm363 Can't the Roadster charge at the full 80A?�
Nov 9, 2013
drees Did you really mean 90A there? I thought the CS-100 was always limited to 80A max since the J1772 is limited to 80A. Clipper Creek's model names are slightly confusing since the model names refer to the size of the circuit breaker that should protect the EVSE.
CS-100 = 80A
CS-90 = 72A
CS-80 = 64A
etc...
http://www.clippercreek.com/uploads/ClipperCreek%20CS%20Series%20Public%20EVSE(1).pdf�
Nov 9, 2013
djp We'll find out when the new firmware is released. The on-board charger was designed to work with the 70A HPC so they'll probably limit it to 70A to stay within the original design and to avoid new QA testing.�
Nov 9, 2013
Doug_G Sorry, I meant to say 70A.
FYI, the newer CS-100's can deliver 80A, but until recently the J cable they used was limited to 75A, so they were only delivering 75.
I'm pretty sure the Roadster will only pull 70A from a CS-100. On the bright side that is still much faster than what a Model S will do on a miles per hour basis.�
Nov 9, 2013
pharma5 I'm right with you on that one. I remember the heyday of speculation a mere two summers ago.�
Nov 9, 2013
hcsharp I've been wondering about that. Do you know who makes the 80A J connector? ITT-Cannon made the 75A version. I haven't seen one of the 80A versions but I know EVLINK (Schneider) announced that they would be coming out with an 80A charger last winter.�
Nov 9, 2013
Doug_G No, I don't know who makes it. The cables are actually branded Clipper Creek.�
Nov 10, 2013
tomsax Clipper Creek has a variant of the CS-100 which they call the CS-100/80. It supports 80A charging but normally provides a 72A pilot signal, which the Roadster recognizes as valid. If you press the Start button twice, it switches the pilot signal to 80A to allow a Model S to charge at the full 80A. So, Model S owners have to know the secret handshake to get the full charge rate.
At Plug In 2013 last month, Clipper Creek President Dave Packard told me that they are currently only selling the CS-100/80 to Sun Country Highway. So, if you've ordered a CS-100 from a Clipper Creek distributor other than Sun Country Highway, you are probably not be getting the CS-100/80 with the dual charge modes.
The Nissan Leaf is the other car that doesn't recognize an 80A pilot signal as valid. I hoping Nissan will get that fixed soon so this whole crazy issue can be reduced to an obscure footnote in the history of the modern electric vehicle.�
Nov 10, 2013
brianman Thanks for the tip, Tom!
I find it somewhat surprising that they made the double-tap work for "older tech" rather than for "newer tech". Going forward, especially now with the Roadster fix, the majority will be wanting what is now "double tap" experience so they have "the wrong default".�
Nov 11, 2013
tomsax I was traveling when I got the news, so I hadn't reached out to our service center to set up an appointment. I just called and found out the update isn't actually available yet. It's expected in the next few weeks. I updated the first post on this thread to reflect that.
- - - Updated - - -
This choice means that any EV driver, mostly likely totally oblivious to this whole issue, can plug in and charge. Only twin-charger Model S owners have any need for the double-tap and if they don't know it, they still get charging at 90% of their maximum charge rate, and 2.3x what they would get at the vast majority of public charging stations.
Defaulting the other way would mean that the Roadster and Leaf owners who don't spend the majority of their waking hours reading online forums would not be able to charge at all.
I'm incredibly appreciative that the Clipper Creek folks came up with a brilliant solution to a problem that Tesla should have fixed years ago and that Nissan should never have had to begin with.�
Nov 11, 2013
100thMonkey Thanks Tom for all your work on this! just talked to Kent/Sun Country and for the time being Sun Country will be going forward with the Dual CS 100 models, for install in WA state. They had quite a few of the original 100's in stock and have had to send them in for upgrading which has delayed things a bit. Sure wish Nissan would hurry up and create a fix for the Leaf, then the dual mode could be done away with.
The speed with which clipper creek came up with a solution was very impressive!�
Nov 12, 2013
dhrivnak I was just informed that this firmware fix is not and will not be available for the 1.5 version cars. That sure stinks.�
Nov 12, 2013
wiztecy What!? That blows. Is there a reason why this isn't available? Resources? Since there are two firmware code paths for the 1.5 vs the 2.x? Possibly Henry's engineering work may bail the 1.5 crew out of this one if Tesla doesn't give us any love.�
Nov 12, 2013
dhrivnak Will try and find out as I get serviced Thursday and hoped to get the firmware update but instead received a short email saying sorry not an option and will not be an option�
Nov 12, 2013
brianman To be clear, I'm totally appreciative of their efforts. I was/am just confused by the design choice.
I wasn't aware there was an issue in this regard for Leaf. I thought it was just Roadster. Interesting and thanks for sharing.�
Nov 12, 2013
Doug_G Well that's the reason right there. It's one thing to educate a few Roadster drivers that they need to push the Start button twice, it's altogether a different matter with many thousands of Leaf drivers.
Definitely better to default it to 90A. Everyone charges immediately upon plug-in. Model S owners with dual chargers can boost it another 10A if they know the "secret handshake". It works for everyone. Makes perfect sense.
Especially since the 1.5 Roadsters aren't getting the 80A fix...�
Nov 12, 2013
hcsharp If you are a 1.5 owner you should call or email your advocate to confirm if this is true or not. Many times we hear things from service centers that turn out not to be accurate. Tom drives a 1.5 and it's hard for me to believe they told him there's an update when there isn't one for his car.
Hope I don't have to make and stock 2 versions of the adapter.�
Nov 12, 2013
wiztecy I inquired about the firmware upgrade and specifically asked if this was for the 1.5 as well and it appears it is from my Tesla Contact:
"The FW update will be for all Roadsters, 1.5, 2.0 and 2.5."
He also said its a few weeks out still.�
Nov 12, 2013
dhrivnak Thank you for the confirmation. Looks like it will be a year out for me unfortunately as I am 300 miles from the service center�
Nov 12, 2013
Doug_G FYI, Ranger fees are now $100 a visit for Roadster too, not just Model S. So it wouldn't be crazy expensive if you really want the update...�
Nov 13, 2013
mknox My 2 CS-100's are on their way. Look forward to trying this out when we get them installed. I wonder if there is any kind of notice on the EVSE about this "feature"?�
Nov 15, 2013
asgard Will it actually charge at 80A or at 70A instead of 55A with the fix? The timing of this fix makes me suspect this is the Roadster coolness Elon referred to in his video.�
Nov 15, 2013
hcsharp It will charge at 70A. Not sure where you got 55A? Currently it won't charge at all if the pilot signal is greater than 72A.�
Nov 15, 2013
dhrivnak True, but with me also wanting Tesla to survive as a company I hate them to make a 600 mile trip for a software update. And to the last poster's comment I very much doubt this is the cool surprise for Roadster owners and even with the fix the Roadster will still only charge at 70 amps.�
Nov 25, 2013
hcsharp I just got this word from the New England Service Manager:
�
Dec 6, 2013
wiztecy I'm scheduled to have the new firmware flashed this Tuesday, does anyone know of any Clipper Creek CS-100 or any 80amp chargers I can test the fix on?�
Dec 6, 2013
asgard There are several at any of the Tesla Service centers, or free CS-100s at their Deer Creek headquarters in Palo Alto.
I charged at Deer Creek at 55A.�
Jan 9, 2014
bart513 Roadster 80 amp Bug Fix Nixed? or just not available yet?
I was disappointed when the service adviser in Queens told me that there is no such bug fix available! Does anyone have other information?
Thanks!�
Jan 9, 2014
dsm363 It is available getting it installed this weekend.�
Jan 9, 2014
bart513 Wow. Am I asking incorrectly or is the service advisor lying or not informed?�
Jan 9, 2014
hcsharp One or the other. The service adviser at the Watertown SC said he actually talked to the engineer who worked on the update. If he's not informed or doesn't understand what you're asking for, have him call Watertown or somebody at HQ in California.�
Jan 9, 2014
ChadS I had asked about this a couple of months ago; I just got email from my service center this morning saying it was available. So looks like the flashing discs from engineering are just now hitting the service centers.�
Jan 9, 2014
hcsharp I also asked at the SC after they told me last month they couldn't update my firmware because they hadn't received the updated firmware:
"Seriously, you have to have a CD in order to flash my firmware!? You can't download that???"
"Nope" he said. "Have to wait for them to mail a CD."
We both rolled our eyes in wonder.�
Jan 9, 2014
bart513 OK so I just called Cali and they are calling my local SC to send them the firmware disc�
Jan 9, 2014
Curt Mine is at the Rockville, MD SC right now for annual service, and they told me they would do the update. I won't know for sure until I get back in town on Saturday.�
Jan 11, 2014
Curt I just picked up my Roadster (1.5) from Annual Service, and the Invoice states that they did a firmware update for the 80Amp charging bug. Roadster reports that the firmware version is now 3.6.12 15.�
Jan 11, 2014
bonnie It was just installed on my Roadster approximately 2 hours ago.�
Jan 11, 2014
dsm363 Funny. I got mine done just this morning too. Glad they finally addressed this.�
Jan 11, 2014
bonnie I'm also having annual service done while there. When I get my Roadster back, I'll drive over to Clipper Creek and repeat the exercise that uncovered the bug to begin with. Just to close the loop ...�
Jan 12, 2014
dsm363 Bug fixed! Charging on CS-100 at 70A.�
Jan 15, 2014
slcasner I was told this update might include lowering the minimum cruise control speed from 30 to 25. Can anyone with the new firmware check this?�
Jan 16, 2014
markwj I've been asking for that for a while. It would be wonderful if someone had listened. 30mph is 48kph, which is too close to the dumb 50kph limits here.�
Jan 16, 2014
tomsax Unfortunately, no. I got the firmware update yesterday and tested that on the way home. 30 mph is still the slowest speed allowed on cruise control.�
Jan 16, 2014
tomsax The firmware is released. I've updated the first post on this thread with the details on the firmware update.�
Jan 16, 2014
100thMonkey Just installed the first dual amp capable Sun Country station at my house and have confirmed that the bug fix works, allowing 70A charging on an 80A capable charger! I have had several pre and post upgrade roadsters test the station (which will go on plugshare soon) and the station works for both! now, if Nissan would get its ars in gear and remove the software bug that prevents Leafs (the other half of the EV market here!) from being fully J1772 compatable, Clipper Creek could skip the whole mass production of the dual am charger, which would be great and just go with 80A. Nissan has refused to address this issue and tells me that clipper creek is not their official brand charger so they don't care, grrrrrr! This Leaf and Tesla owner may not be a Nissan customer much longer, are you listening Nissan? .picture man yelling into desolate canyon with echos reverberating :~(... the answer is of course "No", Nissan doesn't seem to give a crap.�
Jan 16, 2014
djp Did you test both with and without the secret handshake?
I understand the dual amp station defaults to a 70A pilot, which the Roadster will accept and charge at 70A, but if you hit the start button twice it'll present an 80A pilot, which the Roadster should also now recognize and charge at 70A.�
Jan 16, 2014
brianman What a horrible thing to believe and even worse to say to customers.�
Jan 16, 2014
Doug_G That's crazy! Do they really think Leaf drivers never venture farther than 1/2 their range from home???�
Jan 16, 2014
772 Sorry if this is OT, but could you explain what software bug prevents the Leafs from using J1772? Do you mean it does not charge on EVSEs above 24/30A?�
Jan 16, 2014
Doug_G It's the same bug that was just fixed for the Roadster. If the station reports that it can supply 80A, the car refuses to charge. If the station reports 70A then it charges. This is particularly silly for the Leaf as it won't ever draw anywhere near that much current.�
Jan 16, 2014
tomsax Just like the Roadster before this fix, a LEAF can't cope with a J1772 station that sends out an 80A pilot signal, even though an 80A pilot signal is totally within the J1772 spec. We can perhaps almost excuse the Roadster because it shipped long before the J1772 spec was finalized, but the LEAF has no excuse. (I'm a Roadster and LEAF owner.)�
Jan 16, 2014
asgard I am a LEAF and Roadster owner too but my Leaf can't charge at anything over 16A anyway. Are you saying the leaf won't charge at any level if the station sends a max current pilot of 80?�
Jan 16, 2014
772 Thanks for the explanation, and I agree that it's quite silly of them not to fix this. Leaf owners make up a fairly large portion of EV drivers so any public stations would have to keep this limitation in mind when installing chargers. I hope the Leaf can at least charge if the pilot sends a 70A signal.�
Jan 16, 2014
djp Exactly. It the station presents a pilot signal of 80A the Leaf cancels the charge instead of asking for 16A. This is going to be a growing problem as more 80A stations are installed.�
Jan 16, 2014
bart513 Can one set the amperage at a J1772 station? I've always just plugged my roadster in and I believe it has charged at 30A.�
Jan 16, 2014
100thMonkey that's what I'm saying. current J1772 standard includes pilot up to/including 80A, the Leaf can only speak the language up to around 70A. I spent a couple of hours today jabbering my way up the corporate tree at Nissan. the position that I find astounding is that since AV is the only official L2 charging station manufacturer for Nissan, and AV doesn't produce an 80A HAL2 station, that Nissan doesn't care if the Leaf is compatible with a clipper creek 80A station. They literally told me that officially, Nissan does not recommend charging the Leaf on anything but an AV L2 charger, even outside the home, they simply don't support it. I spelled out how ludicrous this is, given that the Leaf's success is actually the main issue right now, that there are way too may Leafs on the road around here for how infantile the charging network is, that the Leaf community is very dependent on non-Nissan official public charging and there is simply no sense in limiting support to only AV charging station since they account for a very small portion of what is available. The guy kept talking in circles and I came close to really loosing it on him. It's going to take a lot more Leaf owners making a stink and being very clear about the request, that the Leaf needs to be fully J1772 pilot signal complient, like every other EV on the road, even the Tesla Roadster, which came out before the Leaf!�
Jan 16, 2014
djp The Roadster will ask for up to 70A and the station will deliver what it's capable of. You can dial down the current in the car, but you can't exceed the max for the station.
Most US 1772 stations are 30A but in Canada we have a large network of high amp stations thanks to Sun Country Highway.�
Jan 16, 2014
100thMonkey The charging amperage for L2 stations is set by the car's charger but the car needs to be able to recognize the signal from the station to even allow charging to initiate. for the time being we are moving forward with dual amperage modified station from clipper creek, the default is 70A and can work with the Leaf, but it's a work around that will surely be outmoded relatively soon and it adds unnecessary complexity to an otherwise beautifully simple "plug and play" charging station.�
Jan 16, 2014
tomsax When a J1772 station is installed, it is programmed with the maximum amount of current it can supply. The limit is based on both the station's capabilities and what the circuit can provide. When a car connects, the station tells the car how much current it is allowed to draw. It is then the car's responsibility to draw no more than the stated current limit.
The J1772 spec released in January of 2010 defines a communication protocol that allows a station to convey a current limit as high as 80A. In the older (2000) version of the spec, the maximum current limit supported by the protocol was 40A. Tesla extended that communication specification to allow 70A charging for the Roadster and Tesla Motors founder Martin Eberhard participated in the committee to update the spec and lobbied them to adopt Tesla's extension. The extension mechanism Tesla created was adopted and defined up to 80A. So, it is a little sad that the Roadster firmware rejected an 80A pilot signal as invalid until this firmware update, but we're glad that problem is fixed now.
Most public stations have a 30A limit, but some are lower and some are higher. Blink and ChargePoint stations, among others, are all limited to delivering at most 30A regardless of circuit capacity. Clipper Creek makes J1772 stations that can deliver up to the full 80A allowed by the spec.
Similarly, when a LEAF sees a 80A pilot signal, perfectly complaint with the J1772 spec, it rejects it as invalid and will not charge at all from that station.�
Jan 16, 2014
bart513 Thank you for the information Tom.�
Jan 16, 2014
TEG http://open-evse.googlecode.com/files/J1772.pdf
Apparently some methods of trying to read the duty cycle start to get error prone as it approaches 100%, particularly if the pilot signal is noisy from the EVSE.
Some charger implementations had trouble reading the 80A signal, and had to use a different method to read the signal to get realiable results.
There are different ways you can try to detect the edges of the square wave and calculate the duty cycle.�
Jan 16, 2014
brianman For those that know more of the history...
Setting aside whether the LEAF has an excuse or not, what is the reason? Was there some collaboration with Tesla (or, um, "unofficial borrowing of technology") or did they just make remarkably similar mistakes?�
Jan 16, 2014
TEG My guess would be that they both made a similar mistake / took the same approach that didn't work properly at the 80A level. I really doubt there was any copying involved. They both might point fingers back at EVSE makers saying that the pilot signal wasn't as good as they hoped... Anyways Tesla steps up to the plate with a creative fix... Is Nissan listening?�
Jan 18, 2014
ibcs The update does not change the cruise control engage speed still 30 mph. One change is that I don't seem to get the error when switching between reverse and drive as often. Seems different, but I could have just finally caught on.
Kent�
Jan 19, 2014
slcasner Thanks, Tom and Kent, for checking the cruise control minimum speed. Too bad that was not changed.�
Jan 19, 2014
tomsax Yes, that was the only other change and only for 2.x Roadsters. It's good to have that confirmed. (I believe that's always been the behavior in 1.5 Roadsters; I frequently pop into D while slowly rolling backwards.) It's mentioned in my description of the changes in my update to the original post in this thread.�
Jan 19, 2014
markwj For people with OVMS, just a few reminders:
(a) Disconnect OVMS before you send your car in. Just unplug it. If you don't, Tesla will (because they need access to the DIAG port to do the firmware upgrade).
(b) Once you get the car back, tap the car boot (trunk) on the "Car" tab of the app, and choose "wakeup". You'll get your temperatures back updating ok after that.
(c) If you no longer have TPMS pressures & temperatures, just drive the car for a minute or so - it will come back.
No problems reported so far, with OVMS and this update.
Regards, Mark.�
Jan 20, 2014
bart513 Thanks Mark. That answers my question so ignore the email that I sent you
I just did what you recommended and the PEM, Motor and Battery temps are back up. The tire pressure and ambient temp never went away.�

tomsax Before turning our Roadster over to the Seattle service center for the update, I unplugged the OVMS. When I got it back and crawled down into the footwell to plug it back in, I found the Roadster tech had already done it. He's been around for years and is obviously used to dealing with OVMS and Tattler. Still, I agree it's a good idea to unplug before turning your car over for service.
If you keep a history of log files for your Roadster, I also recommend downloading the log file before taking it in for service. Although it wasn't an issue with our Roadster for this firmware update, sometimes part (or all) of the log gets reset while being serviced.�

Doug_G Just FYI, Scott got Tesla to agree that the Tattler was neither approved nor disapproved, but was okay to be connected. So service was instructed to leave it plugged in after service. OVMS is probably riding on those coattails, as it were.�

markwj Yes, we got something similar in the early days.
The issue is that they need to disconnect it to get access to the diag port. If they were then to plug it in again, they would be connecting a third party accessory. Some do, some don't.�

asgard I had this issue when they replaced my switchpack under warranty. They disconnected every third party accessory.�

DrComputer Just had the LA service center upgrade my 2.0 to the latest firmware. I have an OVMS. They upgraded the firmware and reconnected my OVMS without any problems. Everything seems to work fine. I now need to have Clipper Creek send me the programmer for my HPC so I can upgrade it to output 75A instead of 70 (since I replaced the Roadster connector with the 75A J1772 end).�

dhrivnak not sure I would bother as there is very little time difference in charging and I am not sure the Roadster could even use the 5 extra amps.�
Jan 28, 2014
DrComputer You're correct. The Roadster will still continue to charge at 70A but my Model S could now charge at 75A.�
Jun 2, 2014
Cottonwood Although the cable is rated at 75 Amps, isn't the HPC supposed to be installed with a 90 Amp circuit breaker. The limit for continuous draw would then be 80% of 90 Amps or 72 Amps. 72 is better than 70, but not by much; is the reprogramming worth it?�
Jun 2, 2014
DrComputer I agree. This is why I haven't bothered to have Clipper Creek send me the programmer. 70A has been fine for 5 years with the Roadster and 1.5 years for the Model S so why rock the boat and change anything.�

jaanton Never mind. Found the first post with the 4.6.8 firmware. So now I have to wonder why they haven't updated my car when it was in the shop.
Can someone who has this fix report what their firmware version is? My 2.5 Roadster is at 4.6.5 and has not been updated for over a year. I guess I do not have the fix. My car has been in for some work just a month ago and no update. (I didn't ask about it. Not high on my radar.)
The version number appears in gray shortly when the car is started.
The Tesla website has firmware release notes that mention 4.6.4 having the HID headlight support.�

wiztecy The thread has the version for the 1.5, (3.6.12 15), but not the 2.x:
Fix for Roadster 80A Charging Bug - Page 7�
Jul 9, 2014
dsm363 I'll check but if they didn't update it last month you don't have the fix yet. They'll take care of it next time the car is in but should ask to make sure they do it.�
Jul 28, 2014
tomsax I updated the first post with firmware versions for both Roadster versions when it was released in January.
Note that the fourth number, the 15, is a hardware version number that doesn't change with firmware updates. Your number may differ. To confirm you have the right firmware, just make sure you have 3.6.12 (v1.5) or 4.6.8 (v2.x).�

mknox The new SCH CS-100 chargers have a dual mode 70/80 amp pilot signal. I had a Roadster visit our office yesterday, and it seemed to work just fine with the 70 amp setting.�
Jul 29, 2014
Cottonwood Clipper Creek put in that 70A/80A mode to get around the Roadster firmware bug. The new firmware should make this mode in the the CS-100 unnecessary. A Roadster with up to date firmware should be able to charge at 70A with an 80A pilot, and the 70A mode is unneeded.�
Jul 29, 2014
bonnie I have the new Roadster firmware and have verified (at Clipper Creek) that my Roadster now can charge at 70A with an 80A pilot. Since this is the same location, car, and ClipperCreek EVSE where the bug was first discovered, I feel pretty confident in stating it is no longer an issue�
Jul 29, 2014
djp I think the 80A pilot is still an issue for the Leaf.�
Jul 29, 2014
dsm363 That is correct from what I've read.�
Jul 29, 2014
Cottonwood Will the Leaf charge with a 70A pilot, or does it need lower?�
Jul 29, 2014
TEG Yes, LEAF charges from 70A pilot.
LEAF charging at 70A (capable) Tesla/Clipper-Creek EVSE at Atascadero Rabobank:
Of course it will only be drawing 3.3kW or 6.0kW [depending on which version of LEAF charger in the car.]�
Jul 29, 2014
Doug_G I can confirm that the Leaf has the same issue, and needs the 70A option on a CS-100.�
