Sudden Range Drop at 80% Charge in Macan 4S

[porschemacanev4S]

I’ve had my Macan 4S since early February and it’s been great. I regularly charge to 80%, 5,400 miles, and all-time average consumption at 2.7mi/kwh.

Earlier this week was showing approximately 230 miles of range at 80%. Suddenly today both in the car and on the app it’s showing only 188 miles of range at 80%. I noticed this in the morning when I got to my car, and again this evening after it completed charging.

I know some degradation over time is expected, but this seems like an extreme drop. Temperatures in my area have been warm and pleasant all week so conditions likely don’t have anything to do with this.

Curious if anyone else has experienced this, if there’s any way to recalibrate, or if this seems significant enough to make a service appointment.

Since March I‘m the happy owner of a Turbo and the 80% Range fluctuates all depending if I’ve been doing a lot of highway driving (going at 130-170km/ph depending on traffic) or mostly shorter trips around town or on country roads. At the moment I’ve only been doing local trips with no highway and at the moment app and car shows a range of around 380-390 km at 80% and when I’ve been doing a lot highway it shows a range of 300-330 km at 80%. Just my experience.

The range changes like that when the AC is switched to MAX. I found I was the cause of the problem, when getting in a hot parked car this time of year.

Range estimation is derived from your consumption the last few hundred miles. Image what happened to me after driving on the German autobahn with 220km/hour average

So, the range estimate doesn’t say anything about the state of your battery, but just extrapolates your recent driving. Nothing to be worried about if (!) you have driving somewhat enthusiastically recently

Hi to All -

I agree with our colleagues’ observations:

commuting at slow city speeds in rush hour traffic vs my 120 mile highway drive to the beach house, aircon or no air con, or no air con and all 4 windows open vs only front windows at highway speeds, night time in rain or dry warm daytime, heavy foot on accelerator enjoying the performance of the car. Wow. All these show variations on battery charge range At next charge.

i think we all love our cars….

hey, i recall driving my ICE 911 C4S or most recently my ICE Macan S hard vs coasting along. That wonderful mileage with Premium Gas price / gallon flashes back as a reminder my driving style in the ICE Porsche vehicles varied so why wouldn’t my Macan 4 EV battery show me my driving behavior costs more or less charging range next time behind the wheel ???

happy motoring to all

Did you ever find out anything on this issue? I think I am having the same issue - my specifics:

- New 4S (under 1k miles.) I had a 2021 Taycan 4S, lease ended, into the Macan now. So plenty of experience seeing the range change under different conditions - this is different.
- Left for a 10 day trip, with SOC at 70%
- Came back and SOC was at 60% - the Taycan would have been at 69%, so that was a surprise. Lets say range was showing ~200 mi
- As I drove it upon my return, it's like the mileage went down correctly and the SOC was not nearly enough - i.e. like they are decoupled now, SOC says 50% but range is 75 miles. But I've actually driven 100+ around town miles, there is no way the SOC only actually went down 10%
- As I mentioned, crazy part is I think the range is actually correct, and the SOC is now not - but I'm just thinking out loud as a start to troubleshoot, and this seemed like a similar situation.
- Or did the sitting do something wonky to the SOC meter... or is half the battery capacity offline... will be doing a charge tonight and checking the numbers of how much it takes and the percentage change...

it’s been weird. I went on a small road trip recently and the trip planner in the Porsche app showed that if I left with 100% charge, I’d arrive at my destination with ~70% charge. Then when I went on the trip, the car showed that I’d arrive at my destination with 80% charge, and it was correct. When I returned home from my trip I arrived with about 20% left. I charged back up to 80%, and the max range at 80% charge was showing ~230 miles and it’s stayed around there since. Seems like the app, the car battery percent, and the range all get out of sync. Good news is that the car in real life seems to be much more efficient than the app or vehicle sometimes think it is.

I started experiencing the same problem recently. IMO this is definitely wrong and must be fixed, but problem seems to be rare. Anyone else with the same issue? Are you going to call the dealer?

I’ve seen similar behavior in other cars, although not to the same degree. Since the guess-o-meter is not your real range, but an estimate based off of habits, it can change drastically when you take a trip vs your daily commute. It’s important to remember that this value isn’t your real range, but just a guess from the recent history. We don’t necessarily lose real range when the number goes down, or gain range when it goes up.

Generally speaking cars don’t seem to factor in idle time too much, but if it’s saying 75 miles range with 50% charge I’m guessing it is factoring in that it used some energy without going anywhere, skewing the guess on future range until that data ages out.

On other models I have seen preconditioning affect the range guess even if the car is plugged in and not losing or even gaining SoC, presumably because traveling 0 miles and using a few kWh will affect the average consumption rate per mile.

In general, you should forget about the range meter. That number we all look at when we get into the car is just an attempt to predict the future.

When you fasten your seatbelt, the car doesn't "know" if you're going uphill or downhill, against or with the wind, whether the heater will be on or not, whether it will be hot or cold, whether you'll use only one motor (normal), or dual motor (sport, sport+), whether your right foot is heavier than usual that day... All it knows how to do is run an algorithm with a lot of past data.

This isn't just the case with our Macan; it happens with all cars.

In my opinion, the best approach is to rely on our own experience, which will tell us how many kilometers we can travel with the percentage of battery we have and the route ahead. And yes, it's not very technical, but it's the best we have.

On the other hand, I've found that the route planner is quite/very accurate. It's capable of predicting, with a very small margin of error (and always somewhat pessimistic) the battery percentage with which we'll arrive at our destination. This is because it has much more information to try to guess the future.

I have just encountered this same 'problem' (or one similar). For the longest time, my GOM has been suggesting 100% is over 330 miles, often as much as 360 miles, despite my general consumption being 3.1-3.2 miles/kwh (294-304 miles on a full charge).

Today, I dropped to 15% SOC before doing a fast charge, and now I have 80% charge with the guessed range of 221 miles, indicating 100% at 276 miles.

This is a much more realistic number based on my driving patterns (maybe a bit low, but it's a closer guess).

I wonder if I managed to stumble into a GOM calibration process by going this low?

 

[Mavshyn]

I'm currently using my own rule of thumb of 20% getting around 100km range. I have so far monitoring my consumption is typically around 5km/kW. So I would guess using the typical consumption for your use case as guide is great. I'm only ever aware of the range when going outstation, which the Porsche charge planner is a great tool for my routes.

I'm sure we all agree on this point - this issue is something very different than the imperfect algorithm of the predicted range changing based on the historical data the system has...

I brought my car in on Friday, no info back yet...
