Re: Nissan issues software update to solve 30 kwh battery issues

It was never Nissan's claim that it cured capacity loss.


Except that what I wrote is "capacity loss problem" - NOT "capacity loss." You can choose to interpret that as "all capacity loss" but that would be silly. Just read it in context.


I think we can all agree the term capacity loss implies permanence which obviously was not the case. At least we are back to where the 24 kwh packs left off where some will do great, some will do good and others should have their heads examined for choosing a LEAF.

But is the car to blame? I know a HUGE fan of the Prius who tried for years to make it work in Phoenix and failed. He now drives a... well something (VW I think) that burns liquid fuel. So its not just Nissan. Cars in general suffer there.

You must be kidding.

When > 50% reach 10 years old and have at least 80% of new battery capacity remaining, we can say "some will do good."
For now, I'll guess that 80% are below 80% by year 3.

"just to report that my '17 leaf got a firmware update today (10/8/2018). 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."


I got a BAFX bt OBD2 scanner today (10/19/2018)(I should have had it prior to the sw update) and got my first battery stats using the leafspy lite from andriod play store. The data is:

AHr=72.72
SOH=91.50%
Hx=76.22%
4 QC and 820 L1/L2

I have never done the QC, so that must be done by dealer before I had it. is this pack in healthy state? according to the formula from this site: https://flipthefleet.org/2018/30-kwh-ni ... reporting/
SOH_post = 57 + 0.43 x SOH_pre, my SOH prior to the update would be only around 80% and should have lost 1 bar already. the calculated AHr_new = 72.72/0.915 = 79.5 was quite bit small (should be around 82?)

Looks like my pack degrades at a rate of 4.32% per 10,000 miles, that leads to the edge of missing the warranty around 64% of SOH at 100,000 miles

Any comment?
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,.

Just as Nissan intended, vomit on their collective corporate souls.
HOWEVER, the longer warranty and starting capacity compared to my 24 kWh LEAF is a marked improvement. Enjoy the silver lining, particularly if you bought the car during the fire-sale
