I kinda missed this article the first time around, then got to reading the
actual paper direct (link here:
https://onlinelibrary.wiley.com/doi/pdf/10.1002/est2.141). Their supposed
experience of the 18650 battery splitting open right down the side is
absolutely outrageous. I spoke with some

No doubt they do. Not many other EV manufacturers
Hi Willie,
When I was studying the battery technology about 10 years ago, the
assumption was that fast DC charging would only go up to 80% SoC. Above
that, you had to reduce power going into the battery significantly in
order to avoid damage. Having talked to several power engineers at my

I've thought about this while supercharging my Tesla. There are situations
where I would be ok using a supercharger a little slower than full bore with

leisurely meal while charging. I know that occupies a supercharger
For many years I've read that high current charging depreciates any battery
faster than lower current charging. The exception is lead batteries, where
some (possibly short) period of initial high current "slam" can actually
extend cycle life. Back in the 1990s, Hawker used to recommend 1C to
Yes, unfortunate and well known (as well as outrageous, IMO).
But would it have been worse if you used DC charging more than once a week, as
they warned against?

Hi All,
[The following is perhaps only of (any?) interest to Leaf owners, my apologies
for wasting everyone else's time)]:
Our 2011 Leaf (56K miles) just this week started reporting 5 (white) bars (& 2
red, which Nissan says is “7 bars”).
Prior to ending my daily 60 mile roundtrip commute ~4
