I got that on my phone as a news item. Some of the "vehicles" they saw were apparently clay models. The Cadillac 'Super Wagon' EV sounds interesting.

The video does have graphics detailing the new "Ultium" battery system, but aside from that it's just a woman talking below stock footage of Mary Berra talking about and showing the Bolt. We get to see the new Cadillac(s) in April, I guess.

One of the moderators of a Bolt FB group put this up recently:
"Everything You Need To Know About Your Chevy Bolt But Were Afraid To Ask"
https://allev.info/2020/02/chevy-bolt-m ... questions/.

I've only had a chance to skim it.

I was pissed off awhile back about slow DC FCing my Bolt when it was cold out (OAT at 44 F) and using an Electrify America DC FC that charges only by the minute at viewtopic.php?p=581197#p581197.

While reading another thread, I found that someone quoted this interesting post: https://www.chevybolt.org/threads/fast- ... ost-475581 about amps and kW vs. battery temp. I wonder how accurate that is. Unfortunately, I had no (and still have no) means of reading battery temp. But, it sounds like it was likely semi-right/close.

interesting. The optimal temp for the Bolt is nearly the same optimal temp for LEAF charging. Only difference is LEAF charges full speed at the beginning but starting temp of batteries appears to control the SOC of the knee (charge rate ramp down)

Now wondering if the full rate charge on cold batteries is a cause of advanced degradation? That theory all but failed on my S 30 but then again, I charged so much due to limited range, the pack was always at a higher temperature most of the time anyway. The E Plus, I was only charging every 2-4 days so plenty of time to cool off the pack.

I have a golden opportunity of sorts to see if charging habit affect this. Up till now, most of my charging has been cold pack DC. Although its only a 4 to 1 DC/L2 charge session ratio, the actual power involved is probably well over 90% DC but that will end very soon. Then I will be mostly level 2 and with the shutdown, not looking like a lot of road trips will be happening.

FYI; my 2nd adjustment started Saturday so we shall see how far it goes. Remember my first adjustment was larger than anyone else's I have seen.

**EDIT** DC power in is 93% of total power used so far.

Chevrolet Bolt EV Sales Jump 36 Percent In Q1 2020
https://gmauthority.com/blog/2020/06/ch ... r-2020-q1/

The Leaf US numbers there are confirmed by https://usa.nissannews.com/en-US/releas ... 0-us-sales. It's interesting that Bolt is so far ahead of Leaf in US sales despite tax credit for Bolt being down to $1875 (https://www.fueleconomy.gov/feg/taxevb.shtml) that quarter vs. the full $7500 for Nissan.

I wonder what Q2 will look like w/the COVID-19 disaster.
