On the theory that the BMS will allow the battery to run down to a lower voltage after the update?

More an open question rather than a theory.

Before the update turtle hit at 3.43 and after at 2.56v


hmm.... so, after the fw update, turtle more may degrades the pack faster.... :?:


:lol:

Yeah... we can assume Nissan did something that outtrumps trump's stupidity which seems to be the norm here

or

we can simply consider the outlandish thought that the BMS is still adjusting to new pack parameters.

Hi so I went to Yorktown heights Nissan and got the recall done, they also did the SOH. I have a 2017 SL Its 1 year old.

The SOH paper came back at 82% and I was a disappointed that it wasn't higher. I park in the shade and do everything I can to keep the car cool.

Anyone get such a low score ( percentage after 1 year) 82%?

Funny thing was I got 5 stars in the 3 categories.

Now with the update: It definitely seemed to be more accurate with the range. When I charged it to 98% it had a range of 111 and I did close to that.
Thankyou,
CS

if u got 111 miles on a charge, I think you are a bit more than 82% SOH

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

I am wondering if anyone has had experience over several months with the software upgrade for their 30 kWh battery. My 2017 leaf has 10K miles and SOH of about 90% according to leaf spy pro. SOH varies between 86% and 94% depending on how I have been charging and driving.

I plan to take my car into the dealer for routine service next month, and to ask for the software upgrade. I am curious if there is any real benefit to the upgrade. I am rather disappointed to see such a large degree of battery degradation in such a short time with so few miles.

By the way, I posted this on another thread and got only one response, so I am also trying here.

There's no benefit to the upgrade other than to clear the way for a future battery warranty replacement, should you need it.

First post; prompted by this request - hi, forum.

New 2017 Leaf SV, owned since 11/2017 at odo 15 mi, upgrade done on 07/28/2018 at odo 10,056 mi
Spy leaf SOH reading immediately before upgrade: 101.84%
Spy leaf SOH reading immediately after upgrade: 101.78%

Average SOH prior: approx. 103% (min/max 101.84/103.6%)
Average SOH since: approx. 102% (min/max 101.12/102.91%) Current mileage 13,000 mi.

So, yes, not much of a change worth mentioning, beyond regular degradation.

Nice numbers! I wish my regular degradation was as good as yours ;)

"beyond regular degradation"

ahhh...like say what?? :)

My 30 kwh LEAF went almost 30,000 miles with "minimal" degradation. Actually quite similar to your "degradation"
