I have "split" off; that is their new name for dual-zone climate. I think it was called sync before. (never used dual climate) Without testing it I would presume with split on both will always show?

I have split zones set. My partner prefers a warmer environment.

This turns on the PTC heater on the partners side, per SMT and CAN bus reader. Significant energy use.

For those with presbyopia this is a safety hazard to look for and put on the reading glasses just to see those small fonts while driving.

My fix? Must Not Update...

But if you can't help yourself, you can try this. Might work even better on the center screen:

TIL....a long drive on range mode to an empty 250KW station gave me 112 KW at at 29%SoC.

SoC plus Power well above 110 until about 63% SoC.

Not sure I understand this. Are you saying with the split mode there are two PTC heaters, one on each side, whereas in non-split mode only one PTC heater is used and serves both sides?

There is only one PTC heater. Alli know is it comes on if you use split mode, at least on my car.

Correct. But your earlier post which I questioned gave me the impression that by using the split mode you will use more energy than non-split mode. I think you meant the heater in any mode results in "Significant energy use", which of course is true.

I'm pretty sure you will use more energy in split mode

Would you happen to know why that is?

 

[aerodyne]

No, all I know is that the CAN bus shows the PTC heater comes on, typically at ambient temps. I tried it now, with OAT north of 90 deg, it did not come on.

On a 5k road trip, have lots of time on my hands while charging...

The biggest impact to me on the 2019 updates has been reduction in SuC speed. I can live with, or been unaffected by the other "gates"

My first and last 5k road trip in late 2018, I saw 116 Kw at about 34% SoC.

Just now, saw 114Kw at 24%. This on a unpaired, 150kw stall.

In 2018, going from 30-80% was like 30 min. After the update, more like 45 min.

slowly, over the last year, I have seen a decrease in charging time. Some due to how I charge, some due I think to software unpayed rolling back battery and charge gates.

my guess is the charge time went from 45 back down to about 35.

Timing the charge now.

39 minutes from 24- 74% Not as much as I hoped for.

There was someone here in TMC showing his fix on Model S PTC heater and on the video was clearly seen multiple sections on the heater core. So I believe if the user allows to “split” the heating on the new SW then it will turn on more sections on that heater to recoup the needed output.

Wow! Is this on an 85 pack? Amazing news if so.

Yes....see sig....BTW, saw 114 Kw at an empty 250KW charger yesterday.

Just great. Looks like about a 25% boost to the current charging curve. Can’t wait for the update.

The weirdest part of V11? When someone is in the passenger seat temp button presents itself. It is not there driving solo.

That makes sense but as usual there are unintended sidequences -- I often pre-warm the seat for my passenger (which is sometimes a pizza box . That's OK, the seats heat up fast.

PTC heater

By the way, what's "PTC"? From context I assume it's the resistive heater, but the acronym doesn't speak to me.

Should define terms. It is the resistive heater, AKA; Positive Temperature Coefficient. Not exactly something that is intuitive, acronym wise..

It's not intuitive when you spell it out.

You saw 114 at 24% though. 33% or so is the CC-CV cutover point where the pack voltage is at max but the cells can still sink max current. What was your charge rate at the 33-34%?

Previously with reasonable California temps and none of what I consider to be thermal throttling, I’ll see >100kW through 50%. Really curious to see if I can replicate your 110ish through 63. That would be amazing.
