2023 60 kWH vs 2022 62 kWH?

Is that shortening the battery life, hard to say since my wife is over +50K miles on her 2018 and she drives it dead, a lot and also charges it to 100% and forgets about it, a lot. Somehow, her battery SoH is still above +90%

Maybe we should dub that pack the "Masochist Pack" - in honor of your wife's poor car.

I just checked her Leaf today and she did finally break the 90% barrier, down to around 89% now, so I have to admire that the pack has even lasted this long. I think she is close to over +400 QC now. I don't understand how she is driving more miles than me per month as I'm averaging between 4k to 5k miles, somehow she tops that and stays ahead of me. I guess we are both in a race to break the 60k miles barrier before the end of the year.

Actually, I do know what it is. When she was driving her ICE (which was a very reliable wagon style vehicle), she had some *mental* limits due to fuel cost, maintenance (oil changes, the usually stuff that is frequent when you drive a lot of miles) in how often she would drive around. Once she got her Leaf and oil changes, belts, whatever, fuel cost goes out the window, now she drives the Leaf so much, she almost lives in it, seems like sometimes.

I have just got a late model "long range" battery pack in the workshop

It is a UK battery build. The label on the battery has a May 2022 assembly date with a stated capacity of 60kWh. Leafspy pro reports it as a 62kWh battery with 97.6% SoH 169 Ah

The car was sold new in November 2022

So it appears the "long range" battery capacity has been downgraded by Nissan, but not by leafspy. Perhaps check with Jim Pollock how leafspy pro determines the original battery capacity

My packs at 97 SoH were also exactly 169 AHr.

My belief is that Nissan started to list something closer to "usable" rather than total capacity. That's why in Europe the pack is sold as 59kWh. When my pack was new, it listed almost exactly 59 kWh on Leafspy.

What's odd is that the epa range went down, but the wltp range went up. Guessing low speeds did modestly better, and higher speeds worse efficiency wise.

While looking up something else, I found https://www.nissan.com.au/vehicles/brow ... icing.html listing 39 kWh usable on non-Plus and 59 on Plus.

That's interesting, so it's possible there is a "lab" difference between the old and new chemistry that helps the battery, but the usable capacity is still higher than my 2020 when it was new. I've never gotten more than 56.5 kWh of usable capacity with my 62 kWh pack. So if the new pack is only rated for 60 kWh but can deliver +59 kWh of power and the Leaf is more efficient than previous models, I wonder why the rated mileage went down?

[DougWantsALeaf]

It's a good question.

In the first 6 months with my Leaf Plus, I did notice it was 50/50 If my car would charge up.to the 59ish kWh or only 56ish. A re-plug to charge would generally bring it up to close to the 59, but I never understood it. I wonder if the bms software was a bit flaky and was letting me overcharge a bit. I did love having close to 800 gids on tap vs. the almost 700 I get now.

Is interesting that the Ariya window sticker says 87 "useable" kWh battery and the Leaf window sticker (2023) says just 60 kWh Lithium Ion battery
