Re: 2016-2017 model year 30 kWh bar losers and capacity losses

That real turtle is the point where a charge test needs to start. I believe the estimations are so far out that people now won't get anywhere near that low as the indications of low GIDs, LBW, VLBW are all coming on at much higher energy still in the pack. I note in your signature your SoH was getting low in October but that may also be under-reporting. This can be highlighted by logging with Leaf Spy as the car continues to be driven at moderate load down to actual turtle and I suspect the GIDs would pause dropping even though you are consuming energy. The good news for you is the firmware update is available in the US (but we can't get it here in New Zealand).jbuntz wrote:I got it to 4 gids. Turtle showing and unable to put it in drive.

Only 2 GIDs between lowest cell at 3.426V now (6 GIDs) and 4 GIDs at 2.832V back then should have far more kWh (GIDs) difference reported which is probably still sitting in the pack.jbuntz wrote:The lowest voltage was 3.426 and turtle had not showed up yet.
From one time back in October I got down to 4 gids. The spread was 233mV and the low was 2.832. Pack at 282v I sense that once you get below 10 gids it is dropping off really fast. On this one, turtle was showing.
[EDIT] I forgot to ask if the voltages were prior to the start of charge or during the charge. Your Hx will swing voltages quite a bit when full current but still big voltage differences from your Oct 4 GIDs to June 6 GIDs.
