Should I read those bottom lines as “charged to 80% and then driven down to X%“? I ask because your note implies to me that was a starting soc taken to 80 and not an end soc.

Stop charging at 80% and start charging somewhere below 15%. Direction depends on whether you are starting with a low SOC or high state of charge.

Thanks for that data. Have you recorded anything similar when the battery is preheated? The one time Iooked at my data, battery starting at 48 degrees F, ambient temp high 30s F, a 125 mile trip at 75-80 mph used the equivalent of 155 miles of range.

All of my tests were done with a preheated battery. Charged to 100% overnight with a departure timer set.

Tom Moloughney did a similar test with a cold soaked battery at almost the same temperature I did ~ 16F and we both got very similar range.

Under low temperatures range will drop because of
  1. decrease in battery chemistry
  2. increase energy demands for heating and cooling of the battery and cabin
I stand to be corrected on this. A little research came up with a decrease in battery chemistry happens at very low temperatures. Below where we ran the tests, so our decrease in range was primarily due to the heating and cooling requirements.

Preheating helps some, but appears less than expected. Once the car is moving, the rush of cold air quickly starts to remove heat from the battery so battery heating turns on.

From my tests. Results are very similar to those from InsideEV but done through a range temperatures.
Would be amazing to see the data split between consumption for engine and consumption for AC/heating. I know the car does not provide this info.

The dip you get over 22°C might only be because of AC usage. Does the battery get actively cooled by the BMS if it reaches 30°C?

I would like to see a graph in Celsius and miles ? .. because that's what I use as an immigrant.

My dealership just called me back about range approvals for 2022 regarding GTS having more range. They confirmed that new approvals for MY2022 are coming for all models and all ranges will be extended on websites soon.

Same here. After all these years (decades actually), it is still harder for me to get an intuitive feel for how hot or cold a temperature is when expressed in degrees Fahrenheit (vs. Celsius) than it is to get a feel for distance in miles (vs kilometers).

I'm a dummy, but this implies that with Porsche's recommendation to use 25% as lowest battery setting when charging, the expected range will be even lower than the lowest one on the graph?

I don't think that the 25% minimum charge setting in the charging Profile has anything to do with running the SoC down to between 5% and 15% when driving on a long distance trip.

That wasn't my experience. It was 18F this morning, the battery was preheated to 62F when I departed, and it bounced between 60-64F the whole way. I had the cabin set to 68F in Eco and, if anything, I was too warm. My calculated range based on % charge lost is 255 miles.

Appreciate the comment. Honestly, this car is not going to do 255 miles at 18F ambient air temperature at 70 mph. I have 2 hours of screen shots at 2 minute intervals saying not and Tom Moloughney has a video on his channel saying the same. At that temperature you will get somewhere around 210-215+/- miles from 100% SOC to 0% SOC. My opinion is that the word "calculated" is the problem.

It could be. I know that the car read 56% SoC when I got back home, and I know the total distance traveled was 61.2 miles. But I didn't look before departing to see what my initial SoC was. It should've been 80%, but I have observed that the car sometimes over-charges by a point or two.

If I left at 82.49% and got home at 55.50%, that would mean I used 26.99% instead of the 24% I'd been assuming. That would lower my calculated range to 227 miles. Which is close enough to your number that any difference could be explained by driving style, whether it was sunny, etc.
