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

Here's my story.

10/30/17
2016 Nissan Leaf SL Mfg 12/15 Del 1/25/16 30 Oct 2017 34172 mi Ahr 67.69 SOH 85% Hx 78.55%

According to the above chart (assuming linear progression) this is where I'm tracking:

34,000 85% CURRENT
45,333 80% BAR 1
61,200 73% BAR 2
77,067 66% BAR 3
90,667 60% BAR 4

Driving/charging Characteristics:

* I do about 50/50 L2|L3
* 95% of my driving is in-town
* I charge to 100% about 20% of the time
* I drive it hard (hey, I'm being honest here)
2016 Nissan Leaf SL Deep Blue Pearl
Mfg 12/15 Del 1/16 30 Oct 2018 50,183 mi Ahr 66.89 SOH 84% Hx 63.55% (w/Nissan sw patch)
Charging: evseupgrade L2 charging 30A circuit @ 24A shared garage heater circuit (ask me)

Looks like I have a 30KWh pack that’s losing capacity also. What point do you have to reach before the warranty kicks in?

2016 SV with build date of 10/2015

Fully charged, LeafSpy says 19.1kWh capacity. Significantly below name plate of 30 kWh. (Understand it was never 30 kWh but suspect is over 25% loss already)


AHr: 52.96
SOH: 66% 394.77V
Hx: 60.83%
odo: 27k
3 QCs
823 L1/L2s
242 GIDs

Drive habits.
75 mile a day round trip (mostly highway) and charge to 100% daily. Battery has degraded to the point I’m bearly able to drive round trip without charging.

At 66% SOH, you're pretty close! I recall someone speculated that 63% is the 4th bar cut-off. Would love to have more empirical evidence to support that.

Could you also update your location info in your profile, so we can get an idea of whether or not extreme heat is an issue in your battery loss?

I live in Birmingham Alabama so it does get warm but not extreme. In fact, the two summers I’ve had the vehicle, the summers have been on the mild side. Limited days above 95 and none above 100. Am worried about the winter and decreased range coming up. I barely make the round trip to work now.

I believe that the real pack killer is very warm days, combined with very warm nights, more than just hot days alone. I imagine that you see a lot of weather like that. As for your Winter commute, slowing down a bit and reducing the heat just slightly should help more than you expect.

Loss of 4 capacity bars on your display (just to the right of the charge bars.)
It is not yet certain what battery capacity that maps to but somewhere around 60% SOH, or about 49 Ahr

Ive only had LeafSpy for a short time and dropped from SOH of 67% to 66% in 340 miles. Trying to extrapolate when i cross 60% at this point would have a significant error. Assuming a few things like its a linear trend and the quality of these two data points is good, I could be at SOH of <60% as soon as another 2,000 miles but suspect its closer to 3,000 miles or within 3 months. Looks like my new years present in January. Making appointment with my local dealer now. Maybe its something easy to fix like a equalize charge (glass half full thought). It works good on wetted lead acid batteries when you first start seeing ICV or specific gravity issues.

For us the question isn't how much longer until it qualifies for replacement, but whether Nissan will replace the pack multiple times. I don't see where they wouldn't be obliged to do so. At current course and speed we will have only gotten 2 years and 20k miles when the fourth bar is lost. Admittedly this car purchased in June 2016 was manufactured in January 2016, so there may well have been damage if it sat for a long time at low SOC, but that time of year is mostly the more moderate temps in central Florida. That said, it had all its bars when it was purchased. The car was a little more "lightly used" for the first several months but is now tracking about 1k miles/month. Unless the time it sat on the lot was a big factor, or replacement packs are somehow improved we could be looking at new packs every 2.5 years or 20k miles at:

replacement 1: 2 years in service, 20k miles
replacement 2: 4.5 years in service, 50k miles
replacement 3: 7 years in service, 80k miles

If the time it sat on the lot wasn't a factor it could be more like:

replacement 1: 2 years in service, 20k miles
replacement 2: 4 years in service, 44k miles
replacement 3: 6 years in service, 68k miles
replacement 4: squeak in just under 8 years in service, 92k miles ?

I even wondered if Nissan would be interested in swapping the car out for an ICE; it would probably save them in the long run, but I think trying to find anyone to talk to about that would just be an exercise in futility.

IIRC, I think there's been at least 1 case of multiple pack replacements under warranty here on MNL on a 24 kWh Leaf. I agree on the latter.
