You are mixing two issues; degradation and battery capping. They are different. Battery capping has NOTHING to do with degradation. Also, the miles displayed at any given State of Charge is just an algorithm consumption figure used to convert energy stored in the battery into a figure. Tesla call that figure miles, but they have only a passing relationship to statute miles, or indeed the miles you should expect from your car.Question about degradation.
I ordered the obd and dongle to test my 2015 85D’s cells, which I assume is capped.
My car is rated to charge up to 270 miles @ 100% charge, which charged up to 258 as of this past May-June. Since then it charges up to 248-250, which I assume it’s because of the software updates..
I typically charge to 80%, which should give me 216 miles. However it gives 200-203 range.
My question is...is degradation solely based on the 270 mile rated capacity only, or both the 270 mile rate capacity and 15 mile discrepancy when I charge to 80%?
All of this capping v degradation stuff is explained in easy terms on page 1 of this thread where there is a Wiki explaining it all. It will save you reading through the previous 8400+ posts.
