Re: 2019 Leaf battery overheating

Ok, was hoping to have more but apparently its so new, most Nissan service advisors have not heard of it but a RapidGate fix for NA now exists. Due to my tech (if you know the area you know why I will wait for him) leaving on vacation at noon today, I won't get the update until Aug 1st. The wait will be torturous.

Is or will there be a TSB for this sent out?

So in the near future, overly cooked batteries with additional degradation, right?

Hmmm, that sounds like what you said about the 30 kwh packs but I saw very little of that and I cooked my pack "a bit"

Link please.
So all the years of Leaf heat related analyzes of degradation noted on MNL resulted in misguided inferences, right?
Yes, Nissan did make some slight improvements in the Leaf's battery tolerance to heat over the years, but hardly
overwhelming or minimizing one's concern for Leaf battery heat. You've never kept any of your Leafs long enough
to really see any significant heat related degradation, besides living in the PNW provides a poor sample base location
for heat related effects.

I reached out to Nissan this morning to get more information on this, and here is the response I received from Jeff Wandell from Nissan's Product and Technology Communications:

"I can confirm that a software update that reduced the quick charging safeguards was offered to customers in Europe. We’re currently investigating offering the software in the U.S. for 2018 – 2019 40 kWh LEAFs but have nothing to announce at this time.
As things progress forward, I’ll let you know of any changes".

Sorry but no cigar, at least I got Nissan to say that they were investigating offering it to US customers, but there isn't any basis that there is an update today.

I get the feeling the battery is insulated sted, which might be awesome come January here, but makes heat dissipation slow in summer.
Battery is not insulated :lol: :lol:
The one bar increase in Temp was due to

1. Large battery thermal mass
2. A large temperature band. Bar #6 and bar #7 in my LEAF are 24 degrees (F) each !!

That was a typo. What I was trying to write was that the temp bar didn’t move all day, in spite of the heat.

Which just goes to show how useless the temp bars are.

My bar #6 starts at 75F and ends at ~ 98F
Bar #7 starts at ~ 99F and ends at ~ 122F
