Your tagline overall efficiency is fantastic if that is for all 10K miles. Can I assume you are in a warm climate. Getting 5.2 is easily achievable here in Chicago May - October, but challenging in the other months when it gets cold.

Danjones, do you have a Leaf or Leaf Plus. How many GIDS does you car show with a full battery?
2018 40 kWh

I use the free version of LeafSpy, and I don't believe it shows GIDs?

I rarely drive over 60 MPH and I am generally in the far right lane on the freeways. If climbing a long grade, my speed may be as low as 45.
I rarely use the A/C even when as hot as 80, i.e. with low humidity. I frequently monitor the battery temp and avoid allowing the temp
over 85-90, which is the max temp where I live in the summer. I attempt to not contribute to increasing the battery temp over ambient
as much as possible.

Did you expect something different from a Nissan dealer, i.e. all Leaf batteries experience relatively high degradation?
Really? Seattle Facebook page has a 150,000 mile Leaf with 10 capacity bars.
An outlier! Your having bought an eTron verses a Leaf2 speaks to your real view.
I still own the LEAF, still being driven almost daily. Past 60k miles and 88% SOC.
Main reason for the eTron is non-electrical. Wife has knee and back problems, and the Leaf is too low.

Do you find the eTron gets the EPA range? I feel like stories are mixed.

LorenFB, I drive very similar to you, which is how I was able to get 220 and 240 mile runs on the highway without anxiety. I drive to the efficiency and power levels, not speed. If I get a tail wind and can do 65-70 for a bit with some traffic, great. If not, I will manage patiently at 50-55 if needed.

Yes, with the same sort of conditions that you expect to give you reasonable range. Less in cold, rain and less at higher speeds.

Your May Numbers Struck me:

May 10, 2020
15,167 miles
64.27 kWh
719 Gids
171.46 AHr
97.20% SOH
111.88% Hx
400.73 Volts

My car with 94.5X% SoH charges to 720 GIDS. SoH and GIDS should tightly align, no? Historically they were lock step. When I had 98.7% SOC, I was still above 750 GIDS. My first GID reading when I had re-enabled LeafSpy on the car was 770 GIDs (triple the highest reading on my 2013 Leaf. So either LeafSpy doesn't align fully to this battery, or SoH is representing something else. I feel like this is further evidence that the BMS is managing down usable capacity to hold down long terms degradation. The mystery deepens.

I had my battery check this morning. My battery is in perfect health according to the report. I have yet to get a battery report show anything else in the 2 (and soon to be 3...details tonight) Leafs we have owned. I asked the tech if they trained him on anything due to the BMS, or these quarterly cycles we have been seeing.... Pretty blank stare in return. I know that will be shocking for this board.


Danjones, do you have a Leaf or Leaf Plus. How many GIDS does you car show with a full battery?
I am beginning to be convinced that the BMS programming is artificially adjusting useable capacity based on use/charge patterns. Gids on my car at full charge have varied. The highest recorded was 737 and the lowest so far has been 714. Here are some key numbers with comments to consider:

730 8/11/2019 189 miles (first full charge)
722 9/02/2019 683 miles (first charge after sitting at airport for over 2 weeks)
737 9/21/2019 2,153 miles (highest reading)
737 10/27/2019 4,630 miles (after first 90-day adjustment)
736 3/06/2020 13,152 miles (start of reduced driving/charging)
735 4/19/2020 14,923 miles (before last 90-day adjustment)
720 4/29/2020 15,383 miles (after last 90-day adjustment completed)
714 6/10/2020 17,200 miles (last full charge)

The numbers were in the 720's and 730's until a downward trend started after the last 90-day adjustment. There were about 6 weeks of reduced daily driving and reduced freeway driving before the last adjustment. As you can see, the number dropped for a while after the car was parked for 2 weeks, but recovered when daily driving resumed.

Danjones, do you have a Leaf or Leaf Plus. How many GIDS does you car show with a full battery?
Yeah, I thought that was a bit strange as well. I just did my 2nd full charge last week (first was done by dealer) and had 731 GIDs. But GIDs is a measure of charge so it would be more in step with ahr.

Now, GID is what is supposed to be in the pack but ahr on your voltage screen is only your "predicted maximum ahr at full capacity" What I failed to do was compare numbers on the screen that shows current "actual" ahr.

SOH is only an overall evaluation of the pack's well, health.

To look at it another way;

Two people both in good health or... are equal in SOH.

One can bench press 300 lbs. the other can only bench press 200 lbs. Now we know that strength is only one part of health so the stronger person isn't necessarily healthier which is why both people have an equal SOH.
