MY26 software update (week 36) for MY24-25

[Petzi]

I don't have to convince you...if I set a fast charging station as my destination and my battery is cold, I can travel slowly or quickly, the battery is heated to reach the optimal temperature,...if I remove the destination, my battery doesn't heat up as much as before and obviously the available range is greater...

you should consider to read the manual:

„Battery conservation function

When the battery conservation function is activated, an overall charging limit of 80% is set for the high-voltage battery. To utilize the vehicle's full range, the charging limit for individual charging processes can be increased to 100% if necessary.

If the battery reaches an excessively high temperature due to external influences, the battery is conditioned (cooled). Depending on the parking time and the battery charge, the temperature range for conditioning is reduced.

Activating the additional battery conservation function lowers the temperature threshold for conditioning depending on the parking time. This reduces the charge level more significantly during longer parking times and at a battery temperature above 20 °C, which has a positive effect on the battery's service life.„

but belive what you want. it is just annoying to read complaints about stuff that does not exist..

i dont think so. preconditioning is always cooling. no preheating. would make no sense

This is not true, preconditioning brings the battery temp to optimal level so the charging process can begin at the fastest rate possible. In warm weather it cools the battery and in cold weather it heats the battery. Usually the driving itself is enough but in extreme conditions it's not.

In sub-zero temps and mild driving it uses a lot of energy and visibly reduces range.

no! porsche stopped to do this months ago. it is deemed not effective.

Interesting, what's the source of this info? I'm pretty sure it worked like this last time I charged my car in 0C temps which was like over the weekend but TBH driving fast also brings the battery temp up.

but @colinthebest is not writing about “extreme conditions “ he seems to believe that the battery is pre heating when a charge stop is scheduled. that is not feasible. the fast charging is heating up the battery very fast. the battery will be cooled when fast charging even in cold conditions.

I'm trying to explain that my car does this all the time, both when necessary and when not, with necessarily higher fuel consumption...

How do you know it's not necessary?

TBH it's hard to tell with Macan because it does not show that preconditioning is active. I was fast-charging the Taycan in ~0C outside and some time before reaching the charger it indicated that preconditioning has started.

I notice this because when my battery is hot (if you scroll on the left display of your dashboard to the ideal battery range graph you'll see that it's in the right range) and I enter the destination at an ionity, instead of maintaining the same range, the remaining mileage decreases significantly; the Porsche mechanics themselves noticed this and they confirmed to me that this latest update almost completely eliminates this problem... When I had the Taycan this didn't happen (there were many other problems but not this one). I conclude by reiterating that it's NOT me saying this but the Porsche charging planner, which regulates the battery temperature based on the outside temperature and the temperature needed for fast charging. If you activate with a cold battery, it charges more slowly and gets damaged more,... if I arrive and it's too hot, it has to cool it down and charges more slowly.... My car is 1 year old and hasn't undergone any other software updates, so when would they have disabled the function? Finally, if the agreement we are talking about expressly indicates the solution to the problem with some NOT necessary adjustments, did I invent it?

do the update. why don't you? why do you complain about something that has been fixed months ago?

In my mind it should works like this:
If you select a charging destination and the battery temperature is outside the optimum range it will heat/cool the battery as necessary.
The optimum range is shown on the right between the 2 brackets.
The 2 extremes of the temperature range are denoted by red on the top (hot) and cold on the bottom (cyan).
Optimum is between the brackets in the middle.
The white line inside the grey range shows you where your battery currently sits temperature wise.
In the below example outside temp is 7degC, battery is 5degC and it shows you its barely half way toward ideal temperature, it needs to be heated.

do the update. why don't you? why do you complain about something that has been fixed months ago?

Pietro,
first of all, I don't have to justify why I did or didn't do an update. I did NOT complain, please read carefully... I expressed a problem affecting my car.
Do you think I spontaneously decided not to perform an update that would solve this problem? Perhaps I didn't receive any news about it before the letter I received two days ago? I remind you that a forum is a meeting place to share experiences and passions.
I'm not here to complain, but what if I were? Do you find it annoying to read complaints about things that don't exist? And I find it rude to call someone you don't know a liar, so what? Let's do this...don't read what I write, I'll do the same to you.
Take care.

@PM4 .....GREAT

Yeah so I’m not sure why are we talking about it Do the update and be happy. It includes improvements to the charging process and range calculation.

OK. But to help you is what I am trying to do. Fact is, that the extensive preheating has been abandoned by porsche. What I do not understand is, that you complain about the preheating -which the car does not do anymore- but more or less in the same sentence argue that preheat is a must. Porsche decided months ago that preheating under normal conditions is not necessary and a waste of energy. so they agree with you?
That your dealer does not inform you properly and obviosly does not perform the scheduled updates and recalls is sad.
