Electricity is not measured in distance, but kWh, at the scale of an EV.

The range shown is just an estimate based on several factors. The main ones are:

• Amount of electricity in the battery: In a perfect world, the same amount of electricity would result in the same range. But all batteries degrade over time, and often faster the first year or so. Whether the range reduction shown is real capacity loss depends on how Porsche manages the buffer they built into the battery. They could be maintaining some top buffer, which means some of the range loss you see is real reduction in battery capacity
• The current environment conditions, like how cold the surroundings are, as another commenter has pointed out
• Your recent efficiency, affected by the temperate, wind, elevation gain, and your driving style

Ultimately, the range estimate is just that, an estimate.

After driving multiple electric cars, my wife's and mine, for several years, I've decided the range estimate is a guess not worth paying attention to. When it really matters like on a road trip, use the built-in trip planner, which on the Macan is pretty accurate, and charge where it suggests you charge.

For daily driving, just pay attention to the battery percentage, and charge when it gets below whatever your comfort threshold is.

You are correct, I was curious because it reflects this range based on your long term average consumption. It does not predict the weather for you next trip or how fast you'll go but it gives you an estimate for your particular driving style and conditions. I would also assume it reflects the SoH of you battery as it should calculate this based on the usable kWh and not just the %SoC.

In my case it's spot on - i'm mostly driving on highways at constant high speed, do a lot of fast DC charging, the battery is often warm. I also noticed it's slowly but surely decreases over time which makes me wonder why.

That’s why I referred to the outside temperature. In cold weather the consumption goes up > predicted range goes down.

if you’ve detected a decrease in range with the same driving profile even during the warm summer months, then that’s strange.

 

[TomekGnomek]

Yes, I detected a decrease in range with roughly the same driving profile - temps dropped but from 30C do 15C which should reduce the need for A/C to cool down without the need for running heat.

This is why I started this thread, I make 3k+ kms monthly and 80% of it on the same routes with very similar conditions. In most cases it's a roundtrip between two cities 350km apart. It usually required two stops to charge, one each way with very little reserve. Lately I need a 3rd stop which makes me think the overall range decreased somehow.

Every EV battery will lose some capacity over time. As far as I know, every manufacturer calculates SOC percentage based on the current capacity. That's what I was referring to in my first point. So, 100% of a new Macan is ~95kWh (100% =95 kWh). Maybe after a year, the battery has lost 5kWh of capacity (5.25%). The SOC on the display will still show 100% when the battery is charged as much as it can be now. (Now, 100% = 90kWh.)

So, even if all other variables are equal, 100% of a new Macan will guess the range based on 95kWh, while that hypothetical 1-year old Macan will guess the range at 100% based on 90kWh.

Natural battery degradation may be why you are noticing a downward trend in your estimated range.

I’m on my 2nd EV now (Audi e-tron the first) and have read and studied just about everything there is about EVs.

Especially in cold climates where I live. Summer +28c winter -28c.

Batteries just don’t perform as well in cold weather. That is a fact. Every other opinion is just that, an opinion, not a fact.

The AC effect you mentioned is nothing in those temps.

I might have come to a wrong forum, as the discussions here seems to be lacking a lot of facts about EVs, that are common knowledge in Europe.

So I won’t be taking part in any more discussions, since it seems quite pointless.

 

[alvaro]

375-380mi I guess, I usually only charge to 80%

 

[Freakystyle]

this roughly 582km at 100% charge, with a rwd Macan EV.

The person you are quoting is talking about 30C temps to 15C temps. That is not nearly in the temperature range to cause a dramatic, noticeable range change.

While extreme temperatures like -28C you mention are going to have a noticeable effect on your battery efficiency, you’re misapplying that to this case of 15C which is still in the operating sweet spot for NMC batteries. I would think that if you’re going to be elitist about what you consider “common knowledge” you’d be very careful to ensure you’re accurate, or bring some data.

Otherwise yes, it is pointless to come in and say something inaccurate, complain that people are stupid and state you’re not coming back.

On my fourth EV here through some harsh winters and cabin heating/cooling are the dominant factor for range variation through most of the seasonal temperature range. Maybe not at the extremes.

Here is some data on range v temperature but it is overall and doesn’t break down the components causing range drop. Point here is even all inclusive it says:

anonymized data from 5.2 million trips taken by 4,200 EVs representing 102 different make/model/year combinations, and analyzed average vehicle trip efficiency by temperature … ​

​

On average, electric vehicles will achieve 100% or more of their rated range when operating in temperatures between 50°F and 88°F (10°C to 31°C).​

Drop from +30C to +15C I mentioned is something you can consider "cold weather" and thus should not affect range.

The AC effect you mentioned is nothing in those temps.

The AC shouldn't have a big impact in the scenario I mention.

The whole point of my post was - external conditions did non change so much to cause this drop in range.

 

[TomekGnomek]

this roughly 582km at 100% charge, with a rwd Macan EV.

Impressive. Clearly one of us does not drive this car the way it was designed for

 

[de0xyrib0se]

I have not seen any noticeable drop in range at a constant outside temperature range and on a common route. Racked up 10K km already.

At this time of year (however), the colder it gets, the more kWs go into warming the car and maintaining it warm. Same with my other EVs.

One thing I would suggest is on cold mornings keep it plugged in. The benefit of having it plugged in (and at 80%) is when the pre-warmup kicks in, it's using grid electricity and not draining the battery. I only go 100% pre-departure on long routes.

Funny you mention it because I always do but the car seems to prefer using it's own batter for heat. You can easily check it - charge the battery, then turn on climate control, you'll see it does not use power from the charger to do this. One of many many many things that is wrong with this car.

Ha, interesting. At 80% or 100% charge? Or regardless of charge level? I'll give it a shot.
