Issues with Macan battery and range

[Fly4ever]

...I wonder if anyone else had check if the kWh the car received according to a charger are the same or nearly the same with what SoC % reports the battery received.
The other day I plugged the car to a 22kW public charger and got 31kWh approx.almost the 1/3 of total battery capacity (33%). SoC however was at 20% when the charging started and went to 70% when it ended.According to SoC I received 50% of battery capacity which is 47,5kWh.Obviously the real SoC was never not even near 20% but rather at 40% which was exactly what I calculated based on the average consumption kWh/100 for the 188Kms of my trip.

You probably just need a rebalance, if you’ve not recently run it down below 20% and let it sit. I have a long thread about running it down and the car climbing in % just sitting while it rebalanced. Seemingly charging out of nowhere. If just one cell is empty it can’t use the energy in other cells.

This isn’t unique to the Macan, of course, but I wonder if it’s a bit more complicated with the way they do split pack for dual voltage. It seems it isn’t really great for range to keep the car topped off without occasionally recalibrating.

Having a similar issue. In my case it looks like the car “lost” 10kWh. It’s also paired with not getting full charge speed and being stuck at max 180kW. Anyway, going on a holiday roadtrip and seeing Porsche when coming back.

Btw: I tried to find out when this happened and I nailed it down to a road trip during Christmas when one fast charge stopped abruptly. Every charge session after that never got max speed anymore and I “lost” a lot of range. I did blame the wind and cold weather on that trip, but since then we had warmer and stable weather with no positive effect. I can only speculate that this “bad charging session” somehow left a few cells in an unevenly charged state .
I’ll keep you posted on what my dealer will find early March.

Edit:
A German youtuber had the same issue on an Audi A6 etron (also PPE).
TL;DR
A BMS/balancing issue


Problem:
Solution (from Audi):

The solution with Audi seems to be to get the factory involved!

It would be nice if Audi had a documented rebalance process you can run at home that we could use on our PPE cars rather than guessing that the Taycan one might possibly work despite being entirely different technology.

The Taycan TSB says to get down to 2% SOC displayed at the low end, which is quite an exciting number for driving around with an inaccurate SOC display!

-20C, range 300km @ 80%

Motorway (100 km/h) hikes the consumption to 26-28kwh/100km in that temp.

Not bad, and it’s such a joy to preheat the car and to also drive in a warm EV. There are cars that really can’t keep warm in these conditions.

Yes, as it should be. Last winter I had no troubles. Now with that imbalance problem I gat max 250km at 100%, and max 150kW at a charger (yes preheated, alone at a 400kW charger)

Does this known issue have a bulltin number or sth? Any details?

Mine (also October 2024) shows 150 miles (240km) at 80% but it’s winter and i drive on highways.

Yesterday. Garage is about 6 C. Drive was about -5 C, and car was parked outside for at least an hour during the drive. 3 miles/KwH implies a range of about 285 miles. 80% would be about 225 miles, which is about what the car showed at the start.

150 miles at 80% would imply a bit over 2 miles / KwH, which is worse than I've ever seen in my car, and I live in NH.

Or, there is a capacity problem. How fast do you drive? What efficiency is your car showing?

In any case, I would look at this from the efficiency pov. Use the car's reported efficiency to back into the implied capacity. E.g. if the car reports 3 miles / KWH but you can only drive 180 miles at 100%, that implies a capacity of 60 KwH instead of the 95 a new battery would have.

I am having serious issues with battery range of my Macan4 bought in October 2024. Loses about 10-15% range over a distance of about 10miles. Recently was identified as having an issue with some battery modules as total range at 80% charge was 120miles. Local dealership informed that was a known issue with Macan EVs and they had fixed 4 of these in the last week. Has anyone else had the same issues, and any advice welcome. Thanks

Hi. Sounds like your dealer needs to run tests on your battery.

Winter cold hurts range for us all.

My 2024 Macan 4 was factory ordered and Built 1st week of July; delivered Oct/2024. I had several teething issues needing to be sorted.

Miles/Charge in winter is approx:
80%-90% is 250-275mis based on sub zero or at freezing temps and how I drove and if at night with lights or daytime.
100% is ~285-290-30miles vs warm seasons more like 390-395miles

Best wishes for your dealer reviews. Warranty will protect you.

Interesting.
Not a lot of people know that
