    I have had practically zero capacity loss in my 8.79-kWh Panasonic NMC prismatic-cell 2021 Prius Prime Limited battery so far in four years and over 36,000 miles, still getting a BEV range of 40 miles on a full charge. I should state that I do baby my battery though—never charging it until I am ready to drive, driving gently, keeping it at no more than 70% SOC when the car is not driven, etc.

    This study confirms that even regular people see no more than about a 10% capacity loss in general.

    Biggest loss of capacity in most Lithium type batteries is from too much heat or too much charging. If you live in a place like Arizona it's going to be a problem sooner than later. Also if you have ADHD / OCD and you're constantly trying to charge your battery up as much as possible, that can create problems too, but usually the manufacture protects you from that, though that was a problem with Teslas a 1/2 dozen years ago.

    Is that German? I have no idea what that chart says... I'm sure everyone else thinks the same. Posting a chart in a foreign language without a description of the point you're trying to make with that chart ain't gonna get you many likes. Do you speak the language in the chart?

    Perhaps you might try Google translate and enter the text and seeing the equivalent in another language. I took a few minutes to look for source paper but didn't have much luck.

    Can you find the original report?

    The reason I ask is the news article suggests OBD ports were used to gather the data. But Teslas in North America lack an OBD port.
