New to me 2015 Leaf S owner. Recieved 4/10/17
AHr = 54.04
SOH = 87%
Hx = 80.55%
Odo 12,163
QC 67 ( before I got the car)
L1/L2 365 ( I've charged only once on L1 and once on L2 Duosida 16A 240V)
Max Voltage Diff 16mV
Build date 11/14
Georgia, off lease

6/16/17 update
AHr = 55.62
SOH = 89%
Hx = 84.08%
Odo 12,966
QC 68
L1/L2 379
Max Voltage Diff 16mV

I suspect that the car sat for awhile not be used and battery improved after being used for normal operation.

800 miles in two months is still pretty low usage but still good to see your numbers improving
 
AHr = 62.17
kWh = 22.6
SOH = 100%
Hx = 98.24%
Odo 30,334
QC 65
L1/L2 1054
Max Voltage Diff 8 mV
3 year lease, trying to extend till march 2018

looks like you have enough QCs to provide some info.

How often have you quick charged 2 or more times per day?

what is generally the highest temp you see on one QC? 2?

what is your normal ambient temp range you see in day to day driving before the QC event?
 
Very rare for me to QC more than once a day. Hardly QC at all really.

Have never seen more than 7 temperature bars.

Tend to QC more in winter, so temps are lower. Rarely in the 90s here.

Don't think I've ever gone over 200 miles in one day. At most 3 QCs in one day, maybe 4, but short sessions, 15-20 minutes mostly.

Yeah pretty much the same as me. With the quick power ramp down on the 24 kwh batteries, I too also rarely charged more than 15-20 mins as well. This meant relatively low SOCs from QCing (generally in the low 70's)

But the 30 kwh LEAF is like a completely different car. Its so easy to do 200 miles. I averaged nearly 110 miles a day in May that included 11 days where I drove less than 25 miles.
 
Took a reading last weekend on 6/18. Our Leaf is now 2 and 1/2 years old and going through it's third hot, Georgia summer. All things considered the battery is holding up well at 92% SOH. I bought the lease out in April b/c of the fairly ridiculous deal NMAC offered. As long as range holds up at 80% or more over the next 4 years the Leaf will have served us well. And who knows, maybe a replacement pack (30 kWh anyone?) will be available by then at a reasonable price!

Mileage 27,329
GIDs 270
kWh 20.9
SOC 97.3
SOH 92
Hx 87.64
AHr 57.34
Avg Temp 82.9
# QCs 51
GOM at full 96 miles

Great stats!
is the average temp just the 24/7 average for your area? Cause that is HOT!

Thanks Dave. That's the average temp from Leaf Spy, so I'm assuming it is the battery temp (not the air temp) but don't really know over what period of time. As you said though, pretty hot. I'm guessing the battery temp in your neck of the woods doesn't typically get that high. :D
 
As a general rule, accelerated degradation for Li-ion batteries occurs above 30 deg. C/86 deg. F. If they spend most of their time between 15 deg. C (59 deg. F) and 30C/86F, you can expect decent life and range.

Actually I see temps in 90's frequently when OAT is in mid to low 80's. Full Sun and open asphalt does it every time but I have the advantage of a marine climate and cool temps every morning. Olympia generally sees 100% (or very near it) humidity every morning all year long. This almost always means temps in mid 50's even during the hottest part of Summer.

Typical Summer weather says highs in upper 70's to low 80's, lows in the mid to upper 50's. I think its the nightly cool downs that save me
 
These are my stats from another 2015 "Atlanta" car.

Mileage 30,867
GIDs 265
kWh 20.5
SOC 97.4
SOH 90
Hx 85.62
AHr 56.36
Avg Temp 82.6
# QCs 32
GOM at full 102 miles

I put about 1,600 miles a month on it and it was bought primarily as a run-about and a work car. I'm looking to 100,000 miles before I replace the battery and hand the key FOB to my son to drive it to high school.
 
Here are the stats from my new to me Atlanta Area 2015 Leaf S

Mileage 12,117
SOC 93.8
SOH 98
Hx 94.59
AHr 61.24
Avg Temp 75.9
# QCs 27
L1/L2 395

Should the AHr and SOH still be that high after 2 years? The Leaf was a lease turn in and was in the Atlanta area all its life.

I drive about 60 miles per day and L2 charge it every night. How often should I check the battery condition with Leaf Spy?
 
Wow oilman, those stats look great. My guess would be that your SOH is higher than expected b/c the miles are relatively low for the age of the car. I'm no battery expert, just a guess. As far as how often you check, that depends on how much you want to obsess over it. :) I check mine every month or two.

Welcome to the "no oil changes for life" club, enjoy your Leaf!

Your numbers are pretty normal considering what appears to be very light usage. LEAFs do not thrive in the garage. The more you drive them, the higher the numbers stay.
 
My stats are better 1 month after I acquired the car. SOH from 89% to 93% !

Odo: 8525
AHr: 58
SOH: 93%
Hx: 89%
272 Gids
21.1 kWh
SOC 97.1%
8 QC 433 L1/L2

3 years on and minimal degradation

your two pictures almost seems like they represent different cars! you are still 396+ on voltage, 95+% on GIDs but then you look at the other pix and??

This is weird to me. I am guessing your ahr , SOH, etc are depressed and needs a reset?

what is your GID value set to?
