MY26 software update (week 36) for MY24-25

[TomekGnomek]

Even at just 100kW, there is no mathematical possibility that this is true. You cannot physically save more than 3 minutes in the scenario you describe due to temperature differences.

I'm doing 4-5 DC charging sessions A WEEK all during highway trips at 140-160 km/h and all using fast chargers over 300kw. At the moment we have ~0C in Poland, -5C in mornings.

What I noticed after the update is the following:
- battery on it's own in these conditions will not reach optimal charging temp even after longs stretches of driving 150 km/h (you would have to do well over 200 km/h)
- preconditioning (preheating the battery) works well and you can see the battery temp rising rapidly 20-15min before reaching the charger
- charging the battery WITHOUT preconditioning in these conditions have a very significant negative impact on overall charging time - like 50% or even more like 2x; this I tried several times after I had to start driving a frozen car in the morning with low SoC and charge it before the precondition had a chance to do it's job - the difference was not 2-3 mins longer but night and day, it took I think 2xx longer than estimated charging time

My car already has the update applied. Just checked it with the dealer. Range remaining during navigation is still off at times and indeed saving profiles under SPORT and SPORT PLUS is not possible.

Thanks for confirming what I see and indeed the charging time is not just a few minutes more, it is substantial and you need to use the PCM Nav under conditions where the battery/outside temp is low. I too can confirm that driving fast over long stretches will not heat up the battery to the point fast charging is enabled …
The new update does not change this, though I hoped it would enable a wider temperature range and better curve, however, I do not see any meaningful differences.

You're just wasting power, my guy. Burning almost 15% of the power you put in at the charging stop isn't saving you time or money just because the first number you see is higher. You only added net 19kWh on the charging stop, and even at 16C and a 120kW starting charge speed, the initial charging speed will close the gap at the charger in less than 3 minutes. So you just spent 90 seconds of extra charging just to avoid 90 seconds of delay waiting for the heat to catch up.

If you multiply all of those 3kW preheating cycles over the course of your trip, it basically adds up to the time saved...and the twice as frequent detours from the route probably means a net time loss.

No, not remotely true. 29kWh in 7 minutes is only possible (and barely, at that) from exactly 10 to 31 percent SOC. And without preconditioning, that would still only take 9 minutes. 10C is simply not enough of a temperature difference to save the kind of time you're talking about.

You're confusing the charging curve with preconditioning through wastefully short charging stops. You could artificially shorten your charging stops even further--why not 5 minutes so you can claim triple time savings?!--but even with the most cherry-picked use case, you're still at 3-4 minutes saved per charging stop. And stopping twice as often just to maximize the waste is a silly plan.

On a full standard stop (21-30 minutes), it's a maximum 10% benefit. Overall data is about a 5% difference on the whole. Contriving use cases where 3 minutes is "big savings" just won't change that.

In support of the above and against previous posters saying preconditioning isn't worth it:

If the start SOC was the same the difference would be maybe 17 minutes saved? At the cost of 2kWh, 80p. Without preconditioning the ENTIRE charging curve is derated: ideally you pre-condition and plug in at <10% SOC and hit 270kW, failing that plug in at 18% and you get 250kW. Without preconditioning? Lucky to get 160kW. So with the real world example above, thats 19 minutes!

I've observed that even if the battery comes up to temperature during the non-preconditioned charge, the charge rate never recovers and remains on the derated curve.

You only have to look at the pro's like Bjorn Nyland driving 1000km and the fastest way (other than driving an ICE car ) is to precondition and ride the >200kW wave up to 50% and then drive on to the next one.

All the more reason for Porsche to give us control - or at the very least - visibility over the preconditioning process while driving. Would be sweet if stopping for >30 minutes to choose to not pre-condition before the charge stop and save ~2kWh.

Someone in another thread said they got an OTA software update (surprised me, wondering if it's true).

Has anyone gotten this (or any other update) via OTA, or just a dealership service call?

Some of us had CarPlay issues out of the blue that seems to be an OTA in regards to the cars hotspot feature, the password policy has been strengthened and so that seemed to have come as an OTA …

Yeah, that's all I've noticed so far is some speculation that it seemed like there might have been an OTA (maybe), but I haven't seen any confirmation. Just wondered if I missed it.

...is there any car procuced from September onwards received the new software update yet?Me and some local friends got our cars with production dates after August, however when our SA entered our VIN in their system to check if any of our cars is a candidate for the update he got a negative answer,no campaign available for any of our cars.
So,is this campaign available also for recently produced cars or only the ones produced until mid summer are able to get it?
Many thanks.

yes it is for every macan of 24 and 25. i just asked the software guru at my pc. i have one 4s from march and a turbo from June. both got the update and the fixes for trunk cover and passenger seatbelt. could it be that the update has been already installed when you received the car. on the other hand there has been an update of the update in the first week of november. may be your SA does not know what he is doing?

why do you not precondition your car? “departure time”

 

[Petzi]

The following generally applies in winter:
1.) The car should have a departure time. This enables perfect (slow) charging overnight, so the car is warm when you set off. (And yes, it recharges automatically if the preconditioning consumes too much power.
2.) Please use the Porsche navigation system with charging planner. The car reliably calculates the best charging plan and prepares the battery for charging. This works perfectly on longer journeys and also provides reasonable data on range and consumption.

As far as I see that does not pre condition the battery it only pre conditions the cabin ... no? Maybe we should start a new threat on charging / pre conditioning as it seems there are different options and experiences ... for me it is clear that as soon as the ambient temp drops below 12C the behavior of fast charging drastically changes and that even long fast drives or even when the battery is heating up during charging it never recovers to the best charging curve. Moreover the theoretical small difference is way bigger then what one would guess ...

Both me and my friends here have serious doubts about our SA and if he really knows what's going on!!He told us that not a single Macan amongst the 100s they sold got the update already, that's why he didn't have the slightest clue about this.
However,for our specific cars it might be possible to have the new software already installed from the factory because some of the issues addressed by the update were already solved in our cars.Some of those issues are the 5G connectivity,the trunk cover rattle,the passenger seatbelt, the lane change assist smooth operation and possibly some other things I don't know about yet.
That's why I thought to ask in here in case there's someone who got the car about the same time we got ours or even more recently.If such a car ever existed (produced after September/udate candidate) then it would be certain ours should have been update candidates too.

my experience is that the departure setting does not preheat the battery to optimal charging temp. however the battery is always warmer than my garage after preconditioning the car for departure. but definitely the charging planer does heat up the battery for optimal charging.

The only other update I've noted is the Android app update of the Sport Chrono/Smart Lift app.

It was never in doubt - it's the cynics / ill informed on this thread whom need the education.
