Remote S shows 97.1 kWh on S100D?

[charliepmayer]

March ‘18 S 100D seems to not want to charge to my summertime highs.
Remote S currently shows “73.8 of 97.1 kWh” at 76% charge.

“Full” charge stops at 97%. What happened to the 100?

Any ideas?

Looks like typical capacity degradation. I believe 100kwh pack has 102kwh or so when fresh off the assembly line. Your 97kwh seems to be due to normal battery degradation.

Keep in mind battery degrades rapidly during first few months and use cycle. Then it slows down.

Do you know which parameter Remote S is pulling? Nominal Full Pack, or Usable Full Pack?

Nominal Full Pack would be 102kWh
Usable Full Pack would be 98kWh

Assuming it's pulling Usable Full Pack, you're right within tolerances.

Also, this figure can fluctuate quite a bit when below 95%.

This is quite concerning. I have a MX P90DL displaying only 77kwh on the Remote S application.

90D batteries are notorious for having small usable sizes, around 81kwh if I recall correctly. So that coupled with say 5% degradation, which is typical after 1 year would get you around 77kwh. My 100d lost 5% after year 1, but only lost another 0.5% in year 2.
