I checked out my Ottawa Hydro bill carefully in prep for the ULO rates, and calculated that transmission, distribution, etc. amounted to about 2.2 c/kWh. Don't know your location, but perhaps your utility charges more for this.

Of course it's impossible to conduct a whole vehicle test at a precise single temperature in the real world. But perhaps you've noticed that the average of 68 and 86 is 77, so the NOMINAL temperature of the EPA "75˚tests" (EPA's own label) is near the midpoint of the range. One could argue that...

The EPA itself refers to these tests as 75˚F tests (to contrast with its 20˚F cold weather tests), because that's the nominal temperature. Of course, there is a temp range allowed, and my personal opinion is that this range is too broad and should be reduced to something like ±5˚F.

There are actually 4 control arms in the front, and at least 2 more in the rear suspension. If you've replaced the 4 fronts (as I have), it's still possible to have the rear ones start squeaking.

1) EPA consumption/range numbers are NOT guarantees of consumption /range for every driving condiiton. EPA consumption/range numbers are weighted averages which include SOME cold weather driving (20˚F), but more than 80% of the driving cycles are at 75˚F. These driving cycles and calculations...

Probably explained by new vs old tires. Tire rolling resistance can decrease by 20% as a tire wears. See my reply to akveluru.

It is fact that new tires have higher rolling resistance than worn tires. In fact, rolling resistance decreases about 20% as a tire wears and tread rubber is removed. So even if you put the exact same brand new tires on your car, you should not be surprised with up to 20% more rolling...

Not well known to normal people perhaps, but auto engineers know that worn tires have lower rolling resistance than new tires. It's becuase there is less tread rubber (in the crown of the tire) in worn tires, and therefore less hysteretic loss in that rubber.

Fortunately, the math has already been done in studies by people who like doing math and are good at it. So governments just need to grab some cohones and do the right thing, rather than play politics, which is what I smell going on in Saskatchewan.

Actually, it is. The sample size (number of flights) is large enough to put an upper bound on the failure rate. Such reasoning is standard practice in reliability testing. And with 4 anomalies in 100 flights, the number of anomalies is also large enough to provide a reasonable lower bound to the...

I also have such a cord (with 14-50 neutral removed, with a big label stating "for EV charging ONLY", which is only used on road trips. I've used it to connect to the stove plug in a cottage and a dryer plug under similar circumstances. Always set the car charging current to 80% of the breaker...

This is a terribly regressive taxation scheme. It's disproportional and projudicial. Fair would be to tax all vehicles based on road damage, which could be based on vehicle weight and yearly kilometers driven. That way the vehicles that caused the damage would actually pay their fair share.

Yikes! That COPD would have killed someone if it had hit them. And its all due to a failure of second stage to execute a reentry burn. It's the first S9 MVAC engine failure I'm aware of, and based on that, the probability of failure is less than ~4% ( 1 failure in ~25 LEO insertions). Not as low...

I think a similar prinicipal in generally operating in most areas that are deregulated. In a derugulated environment, things go reasonably well during normal times, but really fall apart during unusual times, precisiely because the benefits of deregulation result from cutting the corners that we...

Exactly. As an electical engineer I was shocked to learn that Texas has almost no grid interconnection out-of-state. It's a basic premise of electical grid resilience that it needs to be interconnected to other locales that have different consumption, generation, and weather patterns in order to...

Probably the lead shorts that are responsible.

I fear you may be right, although I hope you're wrong. Especially since there's been virtually no news wrt Roadster 2.0 in some time. It definitely feels like Roadster is not even on the back burner, but perhaps on "keep warm" plate.

I'm thinking the vertical tiny red lines labelled as "phantom drain"in the legend is the relevant info. And those do not appear constant... there are many intervals with no red lines.

Interesting progression. Please keep us in the loop when you receive more news from Tesla wrt root cause...

Had a closer look at your Imgur graphs: unless I don't know how to read graphs, they actually don't show a "a constant 0.2 kwh draw no matter what". There are many hours which don't show this .2kWh consumption. The fact that this .2kWh consumption is not, in fact constant, is further indication...

If there is a constant 200W (.2 kW) draw with nothing connected to the circuit, then the meter is faulty. But more likely something actually is connected to the circuit and nobody knows about it. Carefully tracing the wiring might reveal what this phantom power thief is. Electrical power...

No need to guess. Check your purchase agreement and all referenced documents. The SW license agreement will be there.

Note that the TT-30 to 13-50 adaptors are wired for RV use and will not work with Teslas. That's because the TT-30 is a 120V connector and connects the TT-30 hot and neutral to one hot and the neutral of the 14-50. The Tesla, however, does not connect to the neutral at all. So the Tesla TT-30...

Yes. A time constraint is certainly a consideration. However, I've used a TT-30 connection with a M3LR and drawn 24A @120v. Certainly twice the power of 12A@120V. However, 120V conversion is not as efficient as 240V conversion with the Tesla on board charger. That's why the same power at 120V...

The TT-30 is rated for 30A @ 120V, in comparison to a 5-15 (15 A @ 120V) or 5-20 (20A @ 120V). So the TT-30 certainly increases charging rate, but still much less than using a 240V connection through a dryer or stove receptacle. I would highly recommend a 14-50/14-30 extension cord. Mine has...

I think the pillar speakers are tweeters only, and will only reproduce the very highest frequency sounds. The high frequencies are absorbed much more than mid range and low frequencies by upholstery, clothes, and human bodies, and so the tweeters are frequently placed in the car pillars to have...

A model 3 with a hatch would be a fine vehicle variant. For those who aren't morbidly obese and get stuck in the doorway of anything smaller than a two ton truck bed. Murica.

The problem with trying to drive in 6-7 inches of heavy wet snow is that the Model 3 only has 5.5 inches of ground clearance. In deeper snow, you're essentially snowboarding on the bottom of the battery, and the wheels lose contact with the ground. No amount of studs and chains will help this...

Now that there's a SuperCharger at Polo Park, I think there will soon be many more. Hope you're having fun being an EV pioneer there!

The wall connector (HPWC) contains it's own GFI circuitry. In fact, this is mandated by the NEC, CEC, and IEC. Your electrician seems to never have installed an EVSE before, or he wouldn't be that hesitant.

Having two or more EVs drawing 80A is just silly, in my opinion. There is almost no circumstance in which you would need to charge one EV at 80A to fully charge overnight, much less multiple EVs. Even requiring a 200A service for an EV is really only sensible if plan on foolishly simultaneously...

And I get why Tesla is trying to do that. But it's not working out well. Even with the "deep rain" AI auto wiper, they are still a safety hazard. For those of you who live or drive through snowy slush, you will know that the time delay after getting your vision totally wiped out by a truck in...

I had a 100A service, which I upgraded to 200A because the load calculation with 50A circuit for EV charging came to 110A. A 300 service and panel seems like unnecessary overkill to me. Not to mention that 200A service is the largest residential service available here anyway.

That has decidedly NOT been my experience. Tesla service here has been applying the TSBs even without complaint from me. I even came across a Tesla Mobile Service Tech charging at a Supercharger, who proactively informed a third Tesla owner of the charge port improvement, and performed the...

Interesting. The second picture is definitely worse (so I'm assuming it's from you MY) and looks like the camera is looking through a wire screen. There's a superimposed mesh of tiny orange diamonds on the image. I've never seen this before, but it would definately seem to me there's a problem...

Tesla does certify body shops, which would indicate that personnel have received some form of training from Tesla. So "Tesla certified" body shops do exist. While some Tesla body work is not different from other cars, some body work is different. A "Tesla certified" body shop would seem a...

For small scale use, electrolysis can possibly be the most compact solution for hydrogen production. For larger scale use, production of hydrogen through electrolysis is about twice as expensive as production through steam reforming of natural gas. So I would guess these efficiencies of scale...

Too late. Sorry. :(

If that suggestion works, I'll buy a Volt and trade it for a Model 3 as well :)

I brought my Tesla Model3 in to the local SC yesterday for that exact problem. I was in and out in almost exactly an hour. My suggestion: bring your phone and catch up on world news during the hour. Probably the same amount of time you'd spend with a daily newspaper anyway.

Charging interruptions are not normal. There are many possible reasons for an interruption. Power glitch(es) to your house. Excessive voltage drop in your charging circuit (leading the car to believe there is a poor connection in your charging circuit. This is a safety mechanism in Tesla cars)...

Apparently not. It seems that we've got you beat on regulation intensity. Sorry to bounce you out of 1st place ;)

Really? Here, a new receptacle install requires a permit and inspection. Especially if it requires new wiring. Only a replacement of an existing receptacle with a same type does not require a permit.

Yes. My point was the last screen did not show the dash com icon, contrary to your comment.

I think that's the Sentry Mode icon, not the dashcam.

Did you get it inspected?

Interesting! Creative. I guess you could even put a lock on the exterior box if necessary.

Essentially, the notion of taking more or less power (more or less current, in reality) from the motor is correct. And the amount of current taken is infinitely variable (including going from negative to positive or "taken from" to "putting in"), so that's really why there aren't different...

The explanation involving frequency is sort of correct. In reality, in a synchronous motor, the frequency of the rotor and stator magnetic fields/voltages/currents are always identical (that's why it's called synchronous). What really happens is the "slip angle" between the rotating magnetic...
