looks nissan will have a all new ev platform crossover ARIYA out with 300 miles range and liquid cooling battery pack.

https://insideevs.com/news/377633/nissa ... eaf-rogue/

question is will nissan put some sort of cooling system to 2020 leaf battery? otherwise the leaf is dead

I have a 2019 Leaf. I love the car but find some of the navigation warnings (ie. narrow, road, unpaved road) as a total waste and disrupting to my driving experience. I wish I could selectively turn off these warnings. I cannot find a single documentation on this. I am disappointed that you had no luck either.

Not everyone would benefit from battery cooling. If you don't live in a place with hellishly hot summers and you don't use your Leaf for long road trips with multiple QCs, the battery doesn't overheat. Mine never went over 6 bars last summer, and spent all but a few days at 5.
On the other hand, a battery cooling system could become a more effective battery heating system in winter, which would be useful.

Lots of videos appearing today with a dual Motor Leaf

And potential Nismo edition Leaf. I don’t know if those would come to the US or not.

Big portions of the south west though really need that cooling. I had stretches this summer where my battery didn't get below 100F even late at night or early morning. Nobody really knows yet what that will do to 2018s and 2019s, but it can't be helpful.

The 2018 and 2019 cars have a completely different battery chemistry that is much more durable and heat tolerant. As long as the average temp is between the 2nd blue and 1st red bar, the battery will be fine.

Granted the current design has been going strong for almost 4 years now, (2 in hot weather testing at the Nissan Arizona proving ground) and two in the hands of customers, there is yet to be any negative reports on the durability of the new design.

The challenge is that most are still comparing the new battery's performance using the metrics from the earlier designs.

That isn't clear, longer term. There are Li-ion batteries that have full life at 100C and can be wave soldered onto boards at 270C. Sure, only tiny volumes are available, and can't be scaled to automotive sizes. Yet.

Battery technology isn't constant.

As for the 2018/2019 LEAF batteries, only time will tell.

What exactly does "fine" mean? From the data people are posting here, 2018's seem to be approaching 7-10% loss. The loss may indeed be irregardless of heat - it could be completely based on age. My battery SOH seems almost the same as other 2018's here but they have 10x the mileage. But either way, who defines what "fine" means? Tesla owners are reporting 100k miles on a model 3 with only 2.5% degradation.

Or are you saying that the numbers we are watching of Leafspy are meaningless? That our 2018 batteries SOH is actually still near 100%?

About all we can do is compare notes, make observations (e.g. readings vs. capacity bars) and run tests (e.g. range, charge/disharge) to see how closely any of them correlate w/apparent capacity loss.

I shudder when people assert that whatever SOH LeafSpy renders IS their remaining capacity given that Nissan (AFAIK) has never acknowledged nor released any documentation on the values LeafSpy can display. Even w/my 11 bar '13 Leaf's SOH of 81.xx to 83.xx%, I tell people that probably my capacity is around 81 to 83% remaining. And, if needed, I mention the same caveats/disclaimers.

OrientExpress is, for whatever reason, a shill for Nissan. He regularly writes misleading and even wildly inaccurate things here. He should be treated as he'd like you to treat LeafSpy: as entertainment only.
