I should clarify that my theory is: charging to less than 100% yields a wider variance in batt Kapa max values. So if you're trying to do anything with batt kapa max readings the charge behavior might matter. Basically, reinforcing that when people post a single batt kapa max value and ask what it means, the answer is either "it depends" or "basically nothing."
In my experience, charging from something below 50% to 100% on L2 every night seems to yield the most consistent values. Whether those values are more accurate or useful is a different question.
Despite what this thread may suggest, I also believe it's not really worth stressing too much about degradation. If there's a charge behavior that works best for you, that's what I would recommend.
Thanks, that covers it well ... I have always done any Batt Kapp Max checks in the morning, a couple of hours after a full charge, in the hope that the main variable becomes the ambient temperature at the time.
The broad strokes.of our data collection are:
94ah battery
33kwh so "100%" somewhere around 29 depending on your understanding of the two buffers built in.
28 months
20,000 miles starting at 42,500
430 charging sessions
5,235 kwh charge
(so 12-ish kwh, or 1/3-ish capacity, per charge)
3.8 miles/kwh which is bourne out by the read out ... although the roughly 5% of miles done using the REX puts this at more like 3.6.
Batt max has crept up from just over 28, to just over 29, with about a 3 point variation along the way.
What this suggests to me is that the first 40,000 miles were driven and charged more aggressively (miles/kwh average reading was 3.2) ... and that it is possible to "condition" the battery with regular, predominantly slooooow charging to "100%".
