No matter what, it's serving it's 9+ year commuter car purpose for us: 3 years of us driving it before the kids drive it 6+ years around town for high school and extracurricular activities.


URL has been updated. Minnesota driver. Dec '15 manufacturing date.

Date: 10/4/2018
SOH: 89.3%
Mileage: 37231

The 100% charge after software upgrade was....

Date: 6/23/2018
SOH: 93.44%
Mileage: 32830

I'm losing ~0.9% SOH every 1k miles. On track for battery warranty replacement at around 84K miles (about 3 years from now at current driving habits). If that happens, I'd be totally cool with a new battery about 5.5 years into the ownership of the car to get me another 5-ish years.


That would be awesome!!

This is what I was hoping for on my 2018 but sadly after 12,000 miles, its looking like I will be around 85% @ 100,000 miles. Damn....

Just move to Phoenix. :lol:

Yeah, not likely to work. Jennifer in Phoenix is at 94% SOH and is over (probably well over by now) 30,000 miles. She likely won't make the warranty either but still a long way to go. Very interested in seeing where she is at by end of Summer 2019

just to report that my '17 leaf got a firmware update today. I don't have any leafspy data but I feel the update added about 15 - 20 miles to the remaining range reading. the longest range I saw in last summer was about 125 miles with a full charge. Today the range is around 105 with a full charge before the update, and showing 102 remaining + 22 driven right after update. The car was built 11/2016 and I got it in march 2017, now has 20250 miles on it.
2014 S; 33500 miles, returned with 12 bars.
2017 SV; 20000+ miles, 0 bar lost. sw update 10/8/18, feels like 15 miles range back,.

With all due respect, guess-o-meter values are of little value.

Short of Leaf Spy info, more helpful would be starting and ending % state of charge values.

To put it another way, the update may have been written primarily to produce the above changes in displayed estimated range and to "restore" lost capacity bars. The real questions are:

* Is the car's actual range and capacity restored?

* Is this a lasting improvement, or a temporary, illusory one?

* Does this update fix ALL of the 30kwh packs, or just some of them?

Range is restored to "normal" degraded value. This is not a battery fix, its a SW fix.

Range is temporary as batteries will degrade but should not happen immediately (except maybe in Phoenix :) ) like a BMS reset would see.

I have to think that not all packs needed the update. Mine did not seem to. Why, I dk. Could be my driving /charging habits? I did average over 100 miles per day during the short time I had it. Despite the first 3 months of mostly home only charging and 3 semi long inactive periods in 14 months, I still averaged 3-4 QCs per day for the 14 months I had it. But even at 30,000 miles I saw stats near 100% of new so??

I actually think the GOM is extremely accurate (ducking under the table now). If I see X range remaining and continue to drive at or below that speed until the car dies on the side of the road, it will have been almost spot on. I think the perception of it being unreliable is mainly due to that fact that a typical use case does NOT involve arriving at a charger with "---" on the GOM even though that technically is the capability of the car. Seeing triple digits at 100% is at least looking up I think, especially with some miles on the clock.

Because of the way it works, it will work well for some driving scenarios, like yours. Essentially, your last few minutes of driving before shutting the car off at home happen to use virtually the same KWHs per mile as your overall average. It will not, however, work well for most driving scenarios, for most people.
