But what do you have the LSP reserve set to?
There are options of LBW, VLBW, or an adjustable kWh Remaining?
Also what are AHr, SOH, and Hx?

But does appear from the incomplete info you gave the heat resistant battery hasn't lost a lot in one year.

Haha! Proof positive I'm not a data junkie. :D I have the reserve settings at their defaults -- I haven't changed anything. The only thing I changed was my kWh/mile, which is at 4.4kWh/mile (lifetime average; I don't reset it). I'll see about digging up the other things you asked for.

This was also after sitting one day without charging, so maybe I'll run another test immediately after charging.

I wish I could be as optimistic as some of you are. My 2011 LEAF's battery was swapped at the end of April, so I have about 5-1/2 months of data thus far. Unfortunately, I didn't have a way to track degradation on the original battery until about 2014, so I don't know how quickly it was losing capacity, but looking at my data, it appears that I've already lost about 3.8 AHr (from 66.14 when new to 62.339 now). This represents almost a 6% drop in capacity in about 5-1/2 months, or a bit over 1% per month. If extrapolated, I'd be back down to 66% of capacity in about 34 months! Granted, this will likely not be the case, since the past few months have been the hottest months of the year.

It'll be interesting to see what the degradation will be at the one-year point. Hopefully many of us with "lizard" replacement batteries will contribute their findings to the forum so that we can get a better idea of just how much better the newer chemistry is.

BTW, here's the actual numbers (about 8,000 miles of driving):
  • GIDs went from 278 to 270
  • AHr went from 66.14 to 62.339
  • SOH went from 100% to 97%
  • Hx went from a high of 102.30 (about a week after the new battery was installed) to 93.66
Ocean Blue SL-e
Per LEAF Spy as of 06/26/18: 11 bars, 222 GIDs, 53.4 AHr on new (04/30/15) Lizard battery (1st bar lost 12/22/17)
Orig. battery lost 4th bar at 177 GIDs, 43.19 AHr, 44.74 Hx, 65% SOH after 45 months

It is funny, but for someone who will likely be buying a new pack out of pocket whether the pack holds up or not is good news. But somewhere in between - not so much.

thanks for the data. did you notice this Summer being as hot? I seem to remember 2011 being a real barnburner of a Summer, even moreso than your normal inferno... Either way, this is really big since Phoenix provides a much higher bar than anywhere else in the country

drees wrote: Nissan's long capacity warranty on the new 30 kWh packs shows just how well they trust the 30 kWh chemistry over the 24 kWh lizard chemistry. You probably can still expect the lizard pack to lose 30% capacity not too long after 5 years / 60 k miles in the hottest climates.
larger capacity, longer range = less cycles so an "equal" capacity warranty would be in reality a step down. However, time degradation is a factor especially in 2011's that are barely hitting 40,000 miles in optimal climates at 9 and 10 bars so adding years to the warranty is a good sign

TickTock, I understand your original pack's BMS was reset several times and it was showing 12 CBs for a couple of months despite significant capacity was already lost at that time. Looking at the chart in the OP your Gid readings were not affected by these resets and continued to track the actual energy stored in the pack, can you please confirm the resets did not in fact affect your Gids?

Ok, I see it, is this when his BMS was reset? I was thinking about jumps to 281 as if the BMS was thinking the pack was brand new right after reset. Was anything like that observed even for a very short duration? What about AHr, was it being tracked at the time?

Per the earlier thread:
http://www.mynissanleaf.com/viewtopic.p ... ck#p394179

SOH went to 100% and capacity bars went back to twelve and it took six months for SOH and capacity bars to go back to correct values.

Although GIDS were impacted, they were not grossly wrong like SOH and capacity bars.
They jumped about 7% to 10% erroneously high, for two months or more.

Not sure about the reported AHr.

From the earlier graph it looks like the clearing of long term capacity data was done August 2012 and July 2013.
