Got it last night, installed fine this morning. Went out on a 20 mile loop and it is buttery smooth. A bit hard on accel and braking, but otherwise miles better than beta. Going on a 3k mile roadtrip next week, so very timely! I hope phantom braking on freeways is a thing of the past. MS...

So last week, I got an email from Tesla, offering to transfer both FSD and UFSC if I purchase a new in stock Y,X,3 or S by 3/31. My finances (and brain) do not work that fast, so I did not bite. Actually, I did bite a little, and asked them to give me a trade in offer for my 2017 MS...

Here is the work performed with the Tesla part numbers. Maybe someone can offer part numbers for the upgrade that cause data loss, but these parts did not cause data loss for me:

That's odd. I upgraded my 2017 MS from AP2.5 to 3 and the tag-along MCU upgrade, and I lost no trip or usage data. Hmmm.

Yup, I was there a few weeks ago and nav indicated 2 open spots also. I was the only car charging. Reported it through the app when asked to review my recent charge.

That is great news! I'm heading from MN to Vegas in 2 weeks, and I always try to charge up high enough at Green River, UT to skip the old Richfield supercharger.

My mobile technician topped off the battery coolant, which did not appear on the bill. He probably added a pint or so.

I can only offer my own observations regarding cell balancing. About 35,000 miles ago, my 90% charge limit held firmly at 294-295 RM. It was very solid for years. I rarely, if ever, charged and held it any higher than that. If I was going on a road trip, I would schedule it to finish at...

Nope. I just got 2023.44.30.6 and I'm AP3 with USS. 2017 MS

I proactively replaced my 12v battery in my 2017 MS 100D on its 6th anniversary, with no 12v battery errors. Just felt that I should. I have since repurposed the battery as a UPS backup battery for Starlink router. Battery meter says the battery is 99% healthy with low internal resistance...

I must have missed something early on in this thread. Can someone tell me where the NEC requires a GFCI-protected circuit for a hardwired EVSE. The 2023 NEC has no requirement in Art. 625.

I have discovered why my alarm is going off. NOT TESLA SOFTWARE. User error. I can recreate it. When I use summon (key fob summon--not smart summon) to back into my garage, it seems to lock and arm its security system despite "exclude home" status in the menu. I do this very rarely, but...

This happens to me every time the car gets an update. It seems to forget where home is, and sets the alarm even though I have the no lock at home setting ticked.

Do not install the ferrule. The lugs are tested, rated and designed for the THHN stranded wire you install.

92.4 kwh Sorry this is a Model 3 forum. Oops.

90 percent charging since delivery day. 413 cycles 91k miles 6 percent degradation per SMT 2017 MS-100D 40 amp charging on a 72a dual chargers

Ouch. Multiple code violations and bad install. Don't do what this guy did.

Because of Murphy's Law. It's living on borrowed time and will need to be replaced sooner rather than later. I choose sooner, and under my terms. I will see if they let me keep it and take an older battery I have for the core charge.

I have no particular rhythm with this car. It can sit for a few days at a time several times a month, and then I'll drive 500 miles.

I am proactively replacing the OEM 12V battery next week on my Aug 2017 MS100D. Can't believe it has lasted this long. No 12V alerts or warnings. I just think it is time. Plus, winter will be here soon and it can't possibly make it through another cold winter (can it?) Edit: 91,000 miles...

Wowee. He asks for the time and he gets how to built a clock! :)

Cold battery?

I don't see an issue with total overall service load on that 200 amp service, and my opinion (from 1000 miles away) is that you could replace the dryer breaker with a 50 or 60 amp breaker and install a new circuit from the panel to the EVSE. Or, if the dryer outlet is nearby the garage (and the...

Service entrance conductors appear to be #1 AWG, good for 130 amps not 150. Should measure peak demand load to see if any more load can be put on this service.

Does not apply in this case. Common mistake made by internet searchers and electricians, too. Article 625.41 states that the overcurrent protection must be sized for continuous duty. Article 90 describes how Code Chapters 1-4 can be supplemented by additional requirements in Chapters 5-7...

This is the definition of someone with 20 x ("1 year's experience")

Sorry for more bad news, but crimping a compression pin ("ferrule") over the fine stranded wire does not meet listing requirements for the termination at the HPWC lug. The lug in the HPWC does not accept a solid pin as a solution to the FSW issue at the size/ampacity wire you are using. You...

From the mobile APP, do this: --Touch the upper right profile icon (picture of yourself if you have set up your account with a picture) --Touch ACCOUNT --Touch CHARGING --Touch HISTORY --Touch the 'filter' icon in upper right corner --set the filters --download the history to wherever you want...

HPWC has line side current limiting fuses.

Running power to detached structures invokes many more NEC requirements, and they are complex. Rules are different for feeders than branch circuits. Grounding and bonding rules are different. Merely changing what you have in the pipe now might eliminate some conditions that were...

Please perform a load calc on the panel and verify you have capacity for a charging circuit. You do not know what size the feeder to this panel is yet. I would recommend repurposing the 40a range breaker to be your charging circuit, and buy a new tandem breaker for the range. This will help...

Simpull implies individual THHN wires, which is not NM-B. Please verify the conductor type. Oops. I'm wrong. Simpull is now a nm-b variant. Ignore me.

Please post a picture of your electrical panel with the cover off showing the new work you did.

If you go the Emporia route, please read up on what is required by NEC code to show your inspector the results. Refer to 220.87 which allows measurement of the service for 1 year continuously--or if you meet the exception--30 days with several qualifiers attached. "Maximum Demand" is a term...

Before you get too far along, you will need to verify that your panel accepts tandem style breakers. Not all panels do. And if they do, its possible that only at designated locations in the panel. I agree with GG above, that the higher the better for heat dissipation. The inside cover should...

"They exchanged my charger lead with another they had (not a new one) and to date the breaker has not tripped since." What does this mean?

I would feed the HPWC from the bottom to maintain the integrity of the NEMA 3R enclosure. Top mount or rear mount would be to tougher to keep raintight.

That table is not for romex.

Hard to believe it was a conduit sizing issue this late in the installation. Could be a flood plain issue. Chargers do not appear to be installed at the correct elevation above finished grade per the approved plans. Having said that, it looks like it would not be possible to install them any...

Never mind.

Wow. He got the hot and neutral wires reversed on that outlet. Not a very good electrician if he did that wrong, and also left them loose.

I am PE and an EE, and offer the following opinions to further the agitation already in progress: 1) The #3 wire is too large to be terminated at the lugs inside the HPWC, so giving it a haircut is not allowed and is not Code compliant. 2) Installing a 100A circuit to the HPWC itself is not a...

I hesitate to post this, but from UL Standard 489 and EATON (CH) test data: Most molded case circuit breakers tested are suitable for use at 40°C (104°F) ambient temperature continuous use. The terminals are endurance tested in the lab to allow a maximum temperature rise (not absolute...

My 2107 MS 100D is at 77k miles and 90% is 290 miles, and 100% charges up to 319. 90% charging every day all day since new. I recommend charging to 100% slowly once in a while, by adjusting the amps in the car down to 5 amps and letting it charge that way slowly overnight to 100%. Seems to...

If your other car will rarely be driven, then simply have a dedicated 120 volt 20 amp outlet installed wherever you want. Yes, it will experience long charge times, but it is a cheap installation without extension cords.

I hope your installation is perfect in every way. Good luck with your strategy. Also, you may want to read up on the derating requirements of conductor ampacity due to ambient heat, found in the NEC.

Most likely nothing to do with Tesla. Loose connection somewhere, cant tell for sure from pix, but probably owners outlet-to-UMC-plug was loose. How old was the receptacle? Daily plugging and unplugging? Residential grade receptacle or industrial grade? DIY install or electrician?

Need to use a red hat at the connector to eliminate sharp edges from compromising the insulation.

Did I read your first question correctly? You are going to try to use a 60A/1P breaker?
