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

Sat May 15, 2021 8:12 am

Some of the below was posted Reduction gear oil change thread because I realized SOH data on the first drive after changing ATF in our 2016 Leaf SL with 37K miles.

The last charge was on 6 Nov 2020 and Spy Leaf reported State of Health as 96.08% Yesterday 14 May 2021 after a 12.4 mile to mix the Archoil AR9100 additive with the new ATF the SOH was reported to be 96.04%. The 12v battery was disconnected when it was parked. It goes to body shop 28 May.

Nissan put the 40 kWh battery February 2020 at 25K miles. SOH was 99.87 the best I remember.

How do you see your odds of still being in Warranty at the loss of the 4th bar?

So long as we don't have another pandemic and the bars drop every 11k miles like happened between my 1st and 2nd... really good (>90% odds).

Since the software update (done June 21, 2018) we've driven 29222 miles and my SOH is dropping 2.39% every 5K miles. At that rate we should drop the 4th bar at around 82K miles. This means we have to drive it ~21k miles in 34 months (617 miles/month).

Time will tell and I'll keep updating my thread with every bar drop.

If the car lives its life in the same climate, degradation is much more a function of time and not miles driven.
You LEAF battery has degraded ~ 22% since new. The warranty kicks in around 36% degradation.

So e.g. if the car is 5 years old since manufacture, you can expect to hit 36% degradation at 36/(22/5) = 8. 18 years.
Just as Nissan intended. FWIW, Nissan thinks that degradation slows down over time. That has been true in my car. So your chance of winning the battery warranty does not look good to me.

Our 2016 SL OEM 30 kWh battery pack lost 4th bar Thanksgiving 2019 at 25K miles 5 weeks after we bought it. Only history I have it lived in St Louis MO area and BMS was reset Feb 2018.

I think the 40 kWh battery SOH was 99.87% at it's installment Feb 2020 and at 96.08% when it was totalled 7 Nov 2020 after 12K miles of use.

It was fully charged 6 Nov 2020 and when it was totalled the SOH was 96.08% and SOC was 88%. Soon after it was totalled we stripped off the front end including the radiator and condenser because the van that ran the red light and sheared off the nose they impacted the inverter and charger.

We then drove it 2 miles getting up to 68 MPH before we decided to rebuild it. Before we drove it 12 miles 3 weeks ago the SOH was down to 96.06%. After the drive the SOC was down to 77%.

It seems like disconnecting the battery may stop the 0.01 daily SOH decline when parked. I am going to install a blade battery disconnect and test this out when we get it back on the road.

Hobby aside, I'm surprised you don't put the 40 kWh pack into a cheap, crap battery but otherwise in good condition leaf. It might save you countless electronic gremlins that crop up in EVs after accidents.

June 6, 2021 update. 279 GID's, SOH=76.73%, Hx=49.79%. 87863 total miles, 42934 miles on new battery, 145 L3 total, 31 on new battery, 1783 l2 total, 902 on new battery. Little late reporting this month and I'm still driving less than 1000 mi/month. That third battery is looking less and less likely. I'm just waiting to see if Congress can get it's act together and pass a new EV incentive. I'm looking more and more at the Y these days even with the price increases. I'd like to do this before the end of the year and that limits my choices.

I am surprised as well at this point in the game. :)

Due to dealing with Ankylosing Spondylitis for of over 50 years I have limited range of motion. I got both hips replaced on 1 August 1991 so I can walk so so but the arthritis has totally fused my spine many years ago. I have zero head movement so I really got use to the 4 camera surround view. In parking lots and drive thru windows it is awesome to see curbs before I feel them.

We got the 2015 Leaf SV home from Brandywine Maryland just before Christmas and was hell bent on finding out why a car with 27K miles and mint inside and outside was totalled by the insurance company. I knew it did not operate and it had been checked out due to removed fuse panel covers and glove box being in the back seat.

We were troubleshooting it outside still setting on a trailer because we couldn't get it out of park. It being winter I came up with a very bad sinus infection that put me in bed.

In hindsight it may have been Covid-19 because am still dealing serious blood clots in both legs since January. Some fragments filled both lungs so I spent Easter weekend in cardiac care unit getting tPA piped directly into each lung.

Since my 5 months of sickness and no success in getting the car to boots up we have decided to make it our parts car. :)

Somehow my son in the tangled nose saw the front camera and it still worked. Good

My hobby needs were met striping down our 2016 and trouble shooting the 2015. :)

Both are setting side-by-side at The body shop today.
