39A @ 232V is 9.05 kW. That's about 28 miles per hour of charge with 10 kW being 31 miles per hour, or 45 km/hr. Your car has 13 km to full standard-mode charge (I think), and is reporting 20 minutes remaining (or 1/3 of an hour). That comes out to 39 km/hr (close to the 38 it reports). Is some of the power going to other systems ?

I thought we get 31 miles per hour with NEMA14-50

That's what I see too, but that may not line up with the charging time. Subtract your current rated miles from 240, then divide by number of hours remaining. For example, 2 hours 30 minutes is 2.5. When I do the division, I always end up with the full 30-31 miles per hour of charging, although the display shows 22-26. And because the charge finishes on time (at least from the few times I've watched it), that has to be correct.
Can you give me a photo of the large screen while it's charging?

(while we are at it if Americans would kindly sign the petition to convert to the metric system it would be easier for us Canucks to compare without a calculator on hand.)
Ugh... please don't.
I didn't get home until after most of the charging was done. Nonetheless, in case it's useful here's the 17".
Random observation: I didn't notice 'til now that this UI is showing the wrong wheels for my vehicle. The rendering is also missing the spoiler.

North Americans? South Americans? Central Americans? ;-)
You're too close to a full charge, but that's reflecting 28 mi/hr if you consider 7 miles are left to charge in 15 minutes (7/0.25). 39A at 240V is 9.36 kW. 31 * .936 is 29 mi/hr of charge.
I think the charge target is 238.5 (90% of 265), and the math lands a little closer in that case.
But yah, it's pretty close to full so may not be useful for your purposes.
From your screenshots, "+2 mi" means you just started. IMO, you need at least "+20 mi" or "+30 mi" before the "mi/hr" estimation is past the "ramp up" stage.
I routinely see "20 mi/hr" (Rated) within the first few minutes of plugging it. After more time (10m?), it elevates to "26 mi/hr" (Rated).

I believe you need to change your setting to display Ideal instead of Rated, if you want to see the Ideal charging rate.
You all ignoring me? :smile:
Here's what I've said & believe: it depends on what version of software you're running and what setting you have selected. I believe it's doing the wrong thing in 4.x. In 3.x it depends on rated/projected; when set to rated it displays the proper value.

Good point - behavior is likely dependent on SW version. In my case, I am on 4.1, and the charging rate adjusts between Rated and Ideal, pending on the settings.
I agree with this too.
I said earlier in the thread that I thought they baselined it in the wrong mode. It should have been baselined in Rated mode, then the multiplier added to increase it in Ideal mode. Instead, I suspect they baselined it in Ideal mode and then applied the ratio which would give the wrong numbers for both of them. It should be 31 rmph or 37 imph of charge, roughly.

FlasherZ, I remember that you responded to me when I first posted about this after receiving my car, believing something about the baseline is incorrect. I am on v4.1 (1.19.31), and I have seen 30 MPH charge rate, pulling 239V and 39-40A using rated mode.
In other words, same as aviators99.

While I am also a pedantic SOB, I'm primarily responding to this post because it was referenced in a recent thread, and it contains much good info that folks in the future may want to review, and the above text (emphasis mine), might be a bit confusing.
Given that the 10V voltage drop in the example IS WITHIN acceptable limits, it IS something to sneeze at... that is, I believe FlasherZ was saying don't worry about it even thought that's not what the phrase above tends to mean.
That having been said, thanks FlasherZ for the great info... now back to your regularly scheduled programming.
