So ChargePoint has released a new J1772 home charging unit: ChargePoint Home Flex | ChargePoint Overall, it looks pretty nice. Comes with 14-50 or 6-50 pigtails, or it can be hardwired. It is software settable during setup to its max charge rate (I am not sure how I feel about this, I like...

A question for our European brethren: For SR/SR+ vehicles here in the US, they only have two of the three 16a chargers, so they can only do 32a of charging. Is this similar in Europe and so one of the three phases is completely unused (so two phases on three phase charging used at 16a, and the...

I finally got close enough to one of the buck/boost transformers that I see at various supercharger locations to get specs off of it. As suspected, they added these to reduce the input voltage by about 5% using an autotransformer. My understanding is that the second generation charging...

So I have been annoyed by a bug in my car for as long as I can remember. When I get into the car I generally immediately put my foot on the brake and put the car into drive. The trick is that when you put your foot on the brake it takes it a second to "boot up" (some error warning lights...

I helped a friend install a Wall Connector tonight for his soon-to-arrive Model 3. I thought others might find the pictures and parts list useful! (and I am pretty pleased with how the conduit bending came out - five bends in one stick of EMT!) Parts list (all purchased at Home Depot locally...

So first off I have to state that this is not code compliant, not UL rated, and could be dangerous. I have this adapter which allows me to use the Tesla 5-20 adapter on a 5-15 receptacle. This allows me to crank the charge current up to a max of 16 amps...

So this may seem a bit controversial, but now that Tesla is no longer shipping the 14-50 adapters with the UMC / new vehicles, I would like to throw out there that 14-50 is perhaps no longer the logical receptacle to install for home installations. Here are the benefits of a 6-50 receptacle...

So after participating in the forums here since I got my car last year, I have a list of changes and concerns I see in the NEC that I think would be worth sending off to the code panels as they update NEC. I am curious what others think? 625.54 specifies that EV charging receptacles must be...

Wow, I thought these were a rip off when they were like $90. $127 is insane for what it is (and it is a wear item since bad public charging stations have been damaging them). It is just a hunk of plastic and metal. The cynical part in me wonders if this is to protect the Tesla ecosystem and...

Based on data from my Sense Energy Monitor it would appear that after one of the recent software updates the battery charging behavior has changed. Before my battery would drift a couple percentage points over night (perhaps in part due to cold weather), it would not recharge till it was down...

So I have noticed what I think is a new UI element in the Tesla app on my iPhone this morning. I did not drive my car in a couple days (parked outside) and so the battery drifted down to 76% from 80%. Temperatures are right around freezing (plus or minus). I have never seen the snowflake...

I just got home from a week long vacation during which time I set my car to only charge to 50% (normally set to 80%). It was parked outside all week not charging in Portland Oregon and it got down to 67%. So when I came home this evening I set it back to 80%. I have a Wall Connector on a 60a...

I know there are a lot of threads about Model 3 tires here, but I want to ask a very specific question and I am hoping someone has already figured this out. I am generally a very self sufficient person. I have never in my life needed to have a vehicle towed and I have always handled tire...

This is a public service announcement for everyone that charges in a public location. We have frequently told people seeking advice here in the forums that the Tesla keeps the UMC locked to the vehicle when charging (and even after charging is complete). Some have relied on this to keep people...

So at times folks have bashed the Leviton NEMA 14-50 receptacles as being "cheap" here in the forums and folks have often referenced the Tesla documents suggesting the use of a Hubbell or Cooper receptacle of specific models. I really don't know what to think as I have never bought all three...

I accidentally set my M3 to charge today to 90% (normally I always charge to just 80%). What is interesting is that I noticed on my Sense Energy Monitor that the charge started to taper off in speed prior to achieving 90% state of charge. I find this interesting as I had always assumed that...

So there is a lot of debate in the forums about how large a circuit to install for the UMC or whether to install a Wall Connector or not. Some folks advocate that not very much charging current is needed. Others lobby for as high power of charging options as possible. As the weather has...

I just noticed this evening that three of the four rear lights are fogging up. I love my Model 3 to death, but Tesla clearly has some serious issues with wet weather. It rains a lot here. The windshield wiper controls are an abysmal failure. Guess I have a service request to make soon...

I hope everyone was OK! Someone must have been having a little bit too much fun in their M3. Looks like the car is very intact for that far a fall and crash into a tree. Photos: Airborne driver lands in Clackamas County pond (this is outside of Portland Oregon)

A friend of mine called me last night for advice on some electrical issues with charging his two EV’s (Honda Clarity and M3). He had his NEMA 14-50r melt down that his Leviton 32 amp EVSE was plugged into (which he uses for both cars). He then changed over to charge both cars off garage 5-15...

I thought this data might be interesting to some on the forums. I was on vacation for over a week and so my M3 sat in my driveway unused. I normally charge to 80%, but I had set it to only maintain 50% while gone. Yesterday on my flight home I set it back to 80%, so yesterday afternoon it...

I have been helping enough folks with electrical work lately that I figured it was time to up my game and buy a Flir camera in order to identify potentially hazardous situations. (also it is just really cool) I got it today and of course I had to test. Here are some Flir pictures of my Wall...

I have been involved in a number of threads on the forums regarding 277v support via the Wall Connector / HPWC. There seems to be a lack of clarity in what is and is not supported and whether it will require a trip to the service center to "reset" your car if the voltage is too high. Because...

So this morning was the first “cold ish” morning in Portland Oregon. So I had the car pre warm itself for me using the Tesla app to start it. I have noticed this pattern before on my Sense monitor, but this one was such a clear graph that I figured I would post it. It would seem that the...

So yes, I admit, I may have a problem. I bought (most) all of this while waiting for my Model 3 and it was delayed for many weeks (Q3 pushback unlucky soul). I actually have used a decent amount of it already, though I should not scare off potential EV owners. You really can be a totally...

This weekend while load banking a generator using my Tesla as a load source I realized that the gas shocks on the trunk lid conflict with the gasket seal of the trunk. It is not causing any issues at the moment, but clearly over time it will abrade. Do all Model 3’s do this? I did have the...

We had the first serious rains of the seasons here in Oregon today which required major use of the windshield wipers. I have to say I am vastly underwhelmed. The auto mode was way too slow during heavy rain and too fast during low amounts of rain. The UI for selecting them sucks. I am...

I am going on a trip today and so last night I took my car up to 90% overnight. Then this morning I asked it to go to 100% and I watched how long it took (so I could plan for the future). Here are the results as indicated by my Sense Home Energy Monitor. It was about an hour and twenty...

So I know there has been a lot of discussion on the forums of how people have issues with their phone being used as the key. I wanted to provide my feedback on the topic from a positive direction and not just get lost in the noise of "my phone does not work" threads. I believe it is important...

So on at least two occasions now my car has done completely goofy things when plugged in and not attended. The pattern both times looked different, from each other, but this clearly is not right! You can see me get home and charge for the day at 6pm, and then again after going out for ice...

Was doing a Google search tonight to answer someone's forum question (for charging in a campground). This part is basically the same thing (very slightly different internal wiring): Now you could say the left one is much lower production rate than the right hand one, and you could also say...

So someone else mentioned this plug adapter in the forum the other day and so I went ahead and bought one. It allows you to get a NEMA 5-20 adapter for your UMC and plug it into this, and then plug this into a NEMA 5-15 receptacle. First of all- This is NOT UL or NEC rated for what I am going...

All of a sudden today I can't reply to comment threads. Every 10 seconds or so during writing a comment (every time it auto-saves I presume) I get a huge dialog that covers the page with a CloudFlare error. I am guessing that the frequency of the auto-save is causing CloudFlare to blacklist my...

So I was invited and ordered on 4/18. I then got the July pushback email. I have been watching the tracking spreadsheet and what was originally showing daily progress of deliveries tapered off. A friend who also was invited and ordered on 4/18 got his car (also in Portland). I did not. The...

So I am one of the poor souls that ordered my M3 on 4/18 and got the "July pushback" email. That leaves me with nothing to do but order accessories and hangout on the forums (now that I have completed my wall connector and NEMA 14-50 plug installation). I have ordered and received four...
