A Tesla can charge, including DCFC at any battery temp over 0C. Only for
FULL SPEED DCFC, does the pack need to be heated to around 50C..
The problem in Chicago was people with no home charging leaving packs
overnight to freeze and then driving to DCFC for their daily charge
expecting it would
Thanks for the info about the Tesla thermal management relating
primarily to supercharging. Good to know.
> The **2011** Leaf thermal management system sucks.
The 2011 Leaf, basically Leaf 1.0, didn't have the cold weather features
that were added in 2013.
Like Lee, we also have a 2013
Yes, that only applies to full power supercharging on Ternary (NMC). If
you don't preheat (use the nav) a Tesla can still supercharge, but if not
that hot you will get lower peak power as well as a faster taper. This is
why Tesla has integrated supercharging into the navigation system, so it

It’s been in the manual. People just don’t read it. Same for ICE car.

Thanks Phil. I had no idea they ran it that hot during charge. The Tesla guys
at the stealership were clueless.
I just have 24V , 8 cells LiFePO4 on a Bergey wind turbine 280ah.
Best regards

Yes, charging at cold temperatures damages the batteries is my understanding.

Hi Phil etc,
When Tesla says pre conditioning the battery prior to a supercharger is it
cooling the battery
No, if the battery is at 60F it's simply not going to be able to run the
reactions needed to charge. The minimum temp for full speed supercharging
is around 125F. You can enter service mode and check the battery temps
anytime if you are curious. (I have a video on service mode:
Thanks Phil for your thoughtful and informative reply (as usual :-)
I thought about moving my LiFePO4 ups backup batteries outhouse, but based on
the freezing no charge issue, I’ll just leave in the basement.
With regards to Tesla pre conditioning for fast charge - In the summer though

I suspect a lot of people just don't understand all of this. When I had my
first Tesla, I remember talking to many people at superchargers, and this
was in 2015 when most Tesla owners were still early adopters and were tech
savvy, but still the lack of understanding was rampant.

So, in general, this means there are a lot of rideshare drivers using
Teslas - who can't think ahead far enough to charge up at the END of the
work day - while the pack is still warm, rather than waiting for the
next days, when the pack is frozen.

GOOD thing!
Apparently what happened in Chicago is there is a large quantity of EV
owners that do not have home charging. Supposedly a high proportion are
rideshare operators (Lyft/Uber) that lease EVs to use for work.
