To break it down: 7.8% calendar aging * 1.6% cycle aging = 9.27% net degradation.
Cars with 2021 model year and 60k km, degradation will by dominated by calendar aging. Even if we improved cycle aging by 20%, and cut down cycle aging to 1.3%, then the net degradation would be 7.8% * 1.3% = 9.1% net degradation, a 0.17% degradation difference which would be an almost imperceptible difference, not even reaching 1km of range difference. This is not a good example to look at extended cycle aging.
For the bolded (by me) part:
No, it is not even trying. Actually it was supposed to show the opposite (that calendar aging takes the big bite from the battery), read this post from earlier back up:
Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health
I usually use a mantra:
Calendar aging will be the main degrador for at least the first five or eight years.
This is model s p85d, was made 2014-2016. So basically about 8 years old?
If we had 5-5.5% calendar aging the first year, and we could judge the car to have been about 4-5 years old when it passed 150K-200K km?
(it seems like it was only one car that logged this as the data is very close.
If between 4-5 years, the calendar aging would be something like 5*(square root 5) - 4*(square root 5), thats about 1.2%.
5000km would be about 0.25x5= 1.25% the sum should be about 2.45% between 150 and 200K km?
Original range for this car was 407km.
Range a 150K km was 366
Range at 200K km was 356.
10km/407km is 2.46%. Looks so close that it looks rigged but I just took numbers that seems reasonable and the clearest part of the chart.
I guess its a coincidence that it came up this close but in genereal, I have found it to match the research data very well.
After a lot of ”nice” cycles the degradation per cycle often reduce (curve bending upwards) so the degradation per 10000km might reduce.
For the part about Tesla showing 10% at 200K miles, this car had 356/407 = 12.5% at 200Kkm. I havent learned about the degradation thresholds on Model S, ie, the amount the battery can degrade before the range start to decline. It need to be added to this 12.5%.
