Yes and no.

Anytime a li-ion battery is charging, discharging, or even just sitting there the chemistry is breaking down slowly. Charging at higher speeds, charging at higher temperatures, etc. all speed up that break down.

> Supercharging does measurable damage to batteries.

However, I'm calling bullshit on this statement, unless by "measurable" you mean you will maybe lose 1% more battery capacity (which would be maybe 3 miles of range) than someone who coddled their battery. Measurable? Barely. Meaningful? Not really.

My Model S is 5 years old and at 80,000 miles, and I supercharge regularly. My battery has gone from 265 miles to 260, which is inline with what is expected.
