Turbo - red circle of death, perhaps a fix for my car... but battery idle issue

[TurboSpain]

you can force the car to update the SoC shown in the app by using the app to change to battery charge limit %

Yes, that can work. Activating the car's turn signals/horn also works. But be careful, this will wake the car from "sleep" mode and it will consume a little more energy.

Anyway, I don't want to make a big deal out of this. 1% = 1 kWh can mean €0 if you charge with solar panels, or €0.06 x 30 = €1.80 per month with Octopus' Intelligent Go tariff


In our old ICE vehicles, although the loss was less because they had less electronics, it was also compensated for by a little more gasoline consumption to charge the 12V battery...

In summer I drove down from Manchester to Southampton and parked up for 2 weeks at 68% whilst I went on a cruise.

When I got back, the SoC was only 55% which meant I didn't quite have enough range to get to my planned lunch venue on the trip home.

So the loss does matter, although not financially.

My wife's Renault electric has been left for up to 6 weeks with only a 1% SoC loss.

As an aside, I'm on Octopus Intelligent Go too. I never charge the car from solar as it's more profitable to export any excess for 15p/KW and only charge up over night at 7p/KW

Renault may be very efficient, but I still have a doubt. The SoC that cars usually display is calculated using an algorithm (just like the range indicator), and each manufacturer/engineer does it differently. The only known way to determine the capacity of an EV battery is by charging "x" kWh and checking how many "y" kWh it can discharge; everything else is an approximation.

You're so lucky, Octopus only pays me €0.04 for the excess... At least I live in a sunny country

Even if the SoC is wrong and I accept it's possible, the loss of drive-able range is very real which does imply the loss of charge is probably real.

I’m with Petzi on this one, mine also does not loose almost any power when left idle for longer time like a week or two. Same for Taycan.

 

[Petzi]

Yes, sorry for the typo (SoC)

I don't want to start a debate. If someone thinks an EV doesn't lose energy over two weeks, good for them. That's not the case with my car, and I don't think it's the case with most others either. There's a lot of information out there about other EVs, but for Porsche in particular, there isn't much data.

For example, this article summarizes it like this:
https://chargerigs.com/do-electric-cars-lose-charge-when-parked/

It doesn't matter if the energy comes from the auxiliary battery or the main battery, since the auxiliary is charged with the main. We also don't know how the Macan calculates the SoC (because it's a calculation based on the cells, not a direct measurement), but what is certain is that there is power consumption.
The Macan user manual says that it should be left connected to a charger if it's going to be parked for a while. There must be a reason for this recommendation.

thats the point that got sidetracked (again, as always here) by a the debate how often the soc updates in the app. fact is that my car is parked for 13 days and has lost 0% soc

That's why I've said that 1% loss per day is a failure.
My car was at almost 0% per day until around September, and now, it's 1%.
The loaner is at 0%ish.
same conditions: underground, no 4g/5g, constant temperature, no key at proximity, no nothing.

We will see if Porsche find a fix.

The definition of a common problem for a specific car, in this case Macan EV, depends on the average fault rate of similar premium brands (above average).

Recent polls:
SoC >= 1% loss: 20% (common to unacceptably high)

https://www.macanevowners.com/forum...for-a-week-or-longer.23481/page-3#post-350873

Software related issues:
Serious/dangerous: 16% (at least common)
Not serious/dangerous: 65% (absolute majority)

https://www.macanevowners.com/forum...ad-with-your-vehicle.23243/page-4#post-346991

Polls here on the forum are not necessarily representative for all Macan EV users but thats the best we have currently. Manufactures are unfortunately still allowed not to publish results of customer satisfaction surveys, fault rate and road assistance (they don't show up in AAA, AA or ADAC statistics). Based on polls above, I would say it's fair to say some problems are indeed common.

are you serious ? this poll is a joke and has nothing to do with science.
the (negative ) questions are asked multiple times the whole thing has no sense and meaning. Is there no moderation here at all?

IDK this poll may not the be very scientific but it's not that hard to understand.

It also aligns with what the chief service guy at my local Porsche had told me - that given his 15 years at Porsche the new Macan has by far the most new clients returning with different problems.

It's not that hard to believe, once you drive other Porsche models it's quite obvious this one has been rushed to the market. I'm sure after a generation or two it will be improved a lot which we already see by the software updates and MY2026.

polling on a forum is never science,, the bias is always the people that are represented on the forum.
on this forum, there is a lot of people that came before having the car, so we can't say the people are here to report problems in the first place.
that was my case for instance.

You have to be fair, the polling related to the idle consumption is not negative at all, on the contrary.
actually, I was very surprised that 20% of the people on this forum were in my team, with 1% per day, as I thought my problem of over consumption, like the red circle of death/loss of power, was rare.

in the end we will see if Porsche has a way to solve that, because I'm not going to take my car before this problem is solved, and in the meantime the macan loaner is problem free which is a pleasure because it remembers me my first 10 months of ownership

 

[Petzi]

but the question „some serious issues…“ is asked 3 times. may be i am just to stupid to understand the structure of this…

fact is, this forum has several hundred members. i am checking in every other day for a year and I know of 5—6 that are seriously complaining.

Could be, this poll asks HOW MANY issues you have and thats why you have many similar answers with <3 >5 >10 etc

There are far more people affected than just a few complaining, after my thread about suspension issues I got 4 private messages from other Polish users not otherwise active on this forum asking how it got resolved because they have this issue as well.

I will be speaking to my dealer this week about my 1% problem. Hopefully I can get the car booked in for diagnosis in mid January when I'm back from next holiday and will have even more evidence of the SoC drop after another 2 weeks parked up.

I'll let you know through the forum what Porsche will tell me about this problem...
and if the red circle of death/loss of power is actually solved.
Surprise surprise!
