Haven't read the piece yet, but did see some of her posts on one of the Leaf FB groups. When she was screwing around w/the ice to cool the pack, she didn't have Leaf Spy to even monitor the battery temps even though we kept prodding her to do so. She kept claiming she broke her dongle (not sure how). Finally, she wised up, I guess.Evoforce wrote:Her solutions are comical. Uneven cooling of the pack is not a good thing.

I would not be as happy as she seems to be with 8.5% capacity loss in a year but in any case she really should double check that result with a charging test.Evoforce wrote:Her solutions are comical.

40,000 miles driven, 30,000 of them in Phoenix, constant rapid charging, and only 7.5% capacity loss according to Leaf Spy? Over 12,000 miles, that would only be 2.25% degradation. And imagine if she didn't rapid charge so much, and/or if she lived somewhere colder than Phoenix. Unless, of course, the 7.5% capacity loss was caused by 1.) calendar degradation in the bad AESC battery, and 2.) Phoenix, so it wouldn't really matter if she drove 40,000 miles or 1,000 miles in one year, she still would have experienced the same degradation regardless?
But how do you reconcile her Leaf's profile with say Leftie Biker's experience in his 2018?
No her solutions are not comical. I have proven that the air conditioner can be used to cool the battery in a structured test with LeafSpy monitoring the results. I don’t see anything wrong about putting ice on the pack through the service plug hole but this does seem inefficient and messy.Evoforce wrote:Her solutions are comical.

I plan to start using an ice chest cooler, in conjunction the air conditioner, to blow ice cold air through the service plug hole this summer on long trips. Even when/if we get the software upgrade that allows faster charging at higher temperatures, there is still going to be a problem with the battery overheating. Since the EV industry (Nissan and aftermarket providers) are pretty much ignoring the issue, it’s going to be up to Leaf owners to come up with creative ideas to cool the Leaf battery packs.
Saying her efforts are comical is like saying someone crawling away from falling down a flight of stairs with serious injuries is comical. I know the frustration of having to wait, many times, on a slow charge caused by high battery temperatures. The person on the website came up with creative solutions to a very serious problem borne out of desperation and I don’t see YOU doing anything to help.
This is just second hand information mind you (or maybe third or fourth) but I saw a video by Lemon-Tea Leaf where James said that one of his subscribers stated he received an email from Nissan Europe stating that a software update was available and that it would go into distribution soon. The battery management software version for the USA is different for the Europe version so I don’t know how this information applies to Leafs in the USA.DaveinOlyWA wrote: Have you heard/inquired about when 2018's will get the charge curve update?
whats worse is she was working nights driving Uber so was timing her full L2 charges to finish in the mid afternoon Sun of a Phoenix Summer (no garage, no shade, nada)Evoforce wrote:Her solutions are comical.

It is an interesting question whether she knew enough to time her charging so that the car would not sit fully charged for hours every day.DaveinOlyWA wrote:whats worse is she was working nights driving Uber so was timing her full L2 charges to finish in the mid afternoon Sun of a Phoenix Summer (no garage, no shade, nada)Evoforce wrote:Her solutions are comical.

I am quite surprised her pack is still alive.
