40 kw-hr battery in 2016 leaf

[DaveinOlyWA]

With the 40 kW-hr battery in my 2016 Leaf, Leafspy reads erratically for the amp hours. On the 5 minute drive home it bounced around between 200 and 1500.

kW-hr remaning seems to read correctly. SOC is always crazy.

Here are some some numbers from our new 40 kWh in our 2016 SL after its second full charge.

It shows 8 DC charges and 840 L1/L2 charges which I thought would have been cleared. The complete battery pack was changed out but not the vehicle control module.

Dash shows 100% charge. LSP reads 97% now but 105% when I picked it up yesterday. SOH=99.76
38.1 kWh and 362.3 ,Ah
-2,159 Wh
491 GIDs (65.5%) perhaps because LSP defaults to 60 as the battery size.
Hx=280.00%
400.5 Volt battery pack

I still do not know why LSP only shows options for 24, 30, 40 and 60 and saves as a 60 and there is no 62 kWh battery option.

force app stop. Delete cache and user data. Uninstall and reinstall the app. All the LS stats are correct except ahr.

I wonder if this will strand the earlier 2011-2015 model owners to having to do a manual upgrade to the 40 kWH Nissan battery? I will have to call to find out myself and put any info I get here as well.

After 7 hours the 0%-100% charge was complete and charging cable computer stated it took 37.3 kWh to bring it back up to 100% again but that does seem possible because that would be 100% efficiency. The computer in the charging cable may have used some factor like 90% efficiency perhaps.

So, am I right in that you were at 48 gids for LBW and 18 gids for VLBW?

499 gids on full charges sounds about right for a 40 kWh pack (example comparison at https://www.mynissanleaf.com/viewtopic.php?p=534668#p534668).

After 7 hours the 0%-100% charge was complete and charging cable computer stated it took 37.3 kWh to bring it back up to 100% again but that does seem possible because that would be 100% efficiency. The computer in the charging cable may have used some factor like 90% efficiency perhaps.

By "charging computer cable", are you talking about your level 2 EVSE? if so, it's (likely) only going to be able to tell you the amount of energy it dispensed.

It should not go and reduce it by some factor for charging overhead as it has no idea what the overhead is for a connected vehicle. It's most definitely not the same for all EVs/PHEVs.

Thanks for the numbers, so far! (I am actually not interested in the "kWh" readings from Leaf Spy. See https://www.mynissanleaf.com/viewtopic.php?p=481577#p481577 and https://www.mynissanleaf.com/viewtopic.php?f=44&t=14285&hilit=gid+energy&start=1780#p521838. The gid values and voltages for LBW and VLBW and possibly even lower are more interesting/useful.

Today from a 100% charge I put 131.1 miles the 40 kWh battery with GOM showing 39 miles of range left with dash showing SOC = 20%. The estimated and actual driven miles of 170 miles is doable I found by limiting top speed to 45 MPH. Heat was used on the first 15 miles of today's driving. Roads with hills but drove round trip on same roads so hills averaged out going and coming.

This wraps max/min 91.5/170 miles of range per a full charge (and base line data on our new 40 kWh battery received 12 Feb 2020 that was installed in our 2016 Nissan Leaf SL after the OEM 30 kWh battery lost 4 of 12 State Of Health bars as of Nov 2019. Miles per kWh = 4.9 for this full battery usage today.

With the old battery Turtle model would occur shortly after GIDs dropping below 6 but before 4 GIDs were remaining. If Leaf Spy Pro only produced ONE result I would want it to be the GID's info. I do not plan to run the battery below 20% and most likely not below 30% so I have 40 miles of range for the next morning should I forget to charge the night before.

Look at this one:

people are now looking to put non-Nissan packs into the Leaf. How cool is that.

Looks like the openness of the platform is providing many more options now for Leaf owners.

Spending $9,000 - $12,000 for the 34 - 44 kWa option is still a lot to spend on an old Leaf but if the battery pack technology was really better than the Nissan 40 kWa battery that would be a plus. I think in countries that struggle to gain access to EV's redoing an old Leaf may be worthwhile.

I know the range gain of the 40 kWa over the 30 kWh makes a huge difference in drive ability. Nissan really does not offer any larger option than the 24 kWh until 2016 Leafs as far as I know.

 

[GaleHawkins]

Picked up our 2016 Leaf SL with new 40 kWh battery installed. SOH = 99.87%. and a range of 142 miles with 99% charge and was good for 110 actual miles. Cell voltage and QID seems valid. Most of the other Leaf Spy Pro data is garbage.
.

SOH of new battery has dropped by 0.17% per Leaf Sly Pro in the first 10 days that we have had our 2016 Leaf SL back from Nissan. It started at 99.87% and now is 99.70 . After 4-5 charges that rate of lose does not tell me much but time will tell. The OEM 30 kWh degraded at the rate of 12% per year of use. I was not aware that new Leaf batteries SOH starts at 100%. Starting out with SOH near 100% and a 33% larger battery than the OEM 30 kWk battery before our current battery range drops from 150 miles per charge to 107 miles as was the case when the car was new.

You mean the actual range was 110 miles with heat blasting? If the heat was off or the temps mild, I don't want to be a wet blanket wannabe, but is it possible that the new pack is somehow limited to about 30kwh...?

It's limited to 37/38 kWh pet SLP. A 30 kWh will not be good for 170 miles at 45 MPH. Mileage ranges from 90 - 170 miles at 100% charged.
Fully charged currently with GOM reading 151 Miles.

 

[LeftieBiker]

Ok. I didn't see the 170 miles actual max range, just the 110 actual. Great news, then!

Appears even a Nissan install cannot overcome the limitations of the BMS to immediately acknowledge change...

Just did a 140 mile trip with leaf. Still had 20% left. The new 40 kw-hr battery is very nice.

It is amazing that after 4 years they made the car better than when it was new.

Sounds like you could have made it to 170 miles. I got the same result last week but I held it to 45 MPH to make it happen.

When I picked it up on on 12 Feb 2020 SOH was 99.87 and tonight LSP reports 99.69% so I am going to monitor that rate over time. The old battery lost about 38% on 38 months of usage .

It took the Memphis TN district about a month to approve my claim after the shop confirmed my 4 bar loss was real. The service writer told me the $12,500 plus labor was a problem to some one with Nissan.

I had started my warranty claim with a National Leaf customer rep so I updated her. Not sure what she did but it was a game changer results wise. I'm glad I started the warranty claim with National vs a dealership. It's range was down to 60 miles when I got it 5 months ago so having a 150 mile range mind blowing.

Looking forward to more updates. Do you know of anyone else who went from the 30 to 40 kWh battery?

It's an inherent advantage to EVs. Too bad Nissan didn't incorporate that eventuality into the design from Day 1 and all of the fuss of changing packs could have been avoided and simply been plug&play.

What change is a new battery pack BMS is it expected to acknowledge?

2018 Nissan LEAF: 60,000 Mile Update

This was the first year of the 40 kWh Nissan Leaf and the first report on State Of Health I have seen. After 40K miles the SOH was reported to be 92.5% capacity and at 60K miles SOC was at 86.8%. Being in the southwest the temperatures were on the hot side.

"Fast charging was also used regularly, so there were many times when the battery pack’s temperature got quite hot." I wish 'quite hot' had been defined with the Temp reading from LSP.

Well at least we have some SOH data on the 40 kWh Nissan Leaf battery pack. A loss of 7.5% in the first 40K miles and another 5.7% from 40K to 60K miles in a n=1 case shows rate of %of loss ratio did increase which is not I was hoping to see.

At this time I do not plan to do any fast charging and if I do it will just be enough to get home. My goal is to keep the battery at or below 100F if possible and charge at night when air temps should be below 80F. Upper 90's are typically max and only for a few weeks.

With the 33% larger battery when it gets to 8 bars again we should still have a range of 107 miles which was all the car had new per specs in the manual. Keeping it out of an accident is my most important concern on many levels.
