EV drivers struggle to keep battery charged in subzero
temperatures | NewsNation Now
Jan 16, 2024
The harsh cold sweeping across the U.S. is making the
batteries in electric vehicles drain rapidly, causing
long lines at charging stations and forcing cars to be
towed. Correspondent Alex Caprariello joins "NewsNation
Now" with tips on how to safely drive an electric
vehicle in the subzero temperatures.
"NewsNation Now" is a no fluff, no filler newscast
hosted by Nichole Berlie and Connell McShane featuring
up-to-the-minute news drawing from a network of
journalists across the U.S. Weekdays starting at
1p/12C.
NewsNation is your source for fact-based, unbiased news
for all America.

I had no problem with mine. I will admit you use up more power by heating the
seats (5 seats) and steering wheel but I love it at my age.
(minus 7.8 degrees F here the other day)
what happens to some is not unlike how many people who drove to wally world
and their gasoline car battery died while they shopped. I lost count of them.
many of the older Teslas have a 12 volt lead acid battery too.
if not changed out before the cold weather sets in temp will kill that battery first
and not the big HV battery.
the 12 volt one opens the doors, first clue to what is wrong.
the HV battery has a BMS battery Management System to keep it going.
that does not help the 12 volt lead acid one.

that these Tesla owners spend SOOO much $$ on a car
that won't work in super cold temps - which, in this
country, cold weather is pretty much a given in like
70% of the entire nation. True, not this cold, but
what good is an expensive vehicle if one can only drive
it when it is nice outside?
Plus, the not so nice side of me has to say - given
that where I live, about every 5-8th vehicle on the
road is a Tesla, these Tesla drivers around here have
proven to be the biggest 'a..H...' on the road - not
only do they think the rules do not apply to them, they
think that there ARE no rules in addition to being
inconsiderate of others.
"This week's frigid winter conditions in North America
exposed the shortcomings of certain electric vehicles,
particularly Teslas.…
In the Oak Brook suburb of Chicago, Illinois, where
temperatures have routinely dipped way below freezing,
local media reported public charging stations turning
into "car graveyards" because motorists were unable to
power their vehicles.
News story:
"Nothing. No juice. Still on zero percent, and this is
like three hours being out here after being out here
three hours yesterday," Tesla owner Tyler Beard told
Fox 32.
He wasn't alone. Dozens of cars were reportedly lined
up and abandoned at the Tesla supercharging station in
Oak Brook along with multiple charging stations around
Chicago.
"This is crazy. It's a disaster. Seriously," said
another Tesla driver, Chalis Mizelle, who had to ditch
her ride and get picked up by a friend because the car
wouldn't charge.
"We got a bunch of dead robots out here," quipped
another, while Kevin Sumrak landed at Chicago O'Hare
International Airport on Sunday night to find his Tesla
unresponsive. He had to hire a tow truck and drove
around looking for a charging station that worked in
the freezing cold.
"I want Elon Musk to do something about this, it'd
probably help us out," said another hopelessly
optimistic Tesla owner.
However, Mark Bilek of the Chicago Auto Trade
Association said that drivers were missing a trick.
"Like any new technology, there's a learning curve for
people," he told Fox 32. "It's not plug and go. You
have to precondition the battery, meaning that you have
to get the battery up to the optimal temperature to
accept a fast charge."
But it's really not that simple. Preconditioning also
drains the battery. Even looking at Tesla's own "Cold
Weather Best Practices" is like playing 4D chess if you
need to take a trip in the dead of winter.
"Tesla recommends activating climate settings at least
30-45 minutes before departure," it reads.
"Preconditioning times depend on outside temperature
and other factors. The mobile app will notify you once
your vehicle has reached the desired preconditioning
temperature."
"Tesla recommends using Trip Planner to navigate to a
charging location for at least 30-45 minutes before
arrival to ensure optimal Battery temperature and
charging conditions," the document continues. "If the
drive to the charging location is less than 30-45
minutes, consider preconditioning the Battery before
driving."
In Canada, Mark Bohaichuk made a widely read
observation on hellsite X after meeting a Tesla driver
stranded in -45°C (-49°F):
So why is this happening? The problem is that battery
basics simply do not work well in freezing conditions.
Ions inside EV batteries travel between the positive
and negative electrodes through a liquid electrolyte.
As it gets colder, that liquid, at least in most
lithium-ion batteries, thickens, meaning the ions move
more slowly. The slower the ions move, the greater the
resistance. The greater the resistance, the faster an
electric vehicle loses power.
The solution is to keep the battery warm, but the heat
comes from the battery itself, so these stricken Tesla
drivers are draining the battery just to be able to
charge the battery, and we don't need to explain why
that might be inefficient.
Scientists are working to tackle the issue. South 8
Technologies, for instance, propose a "Liquefied Gas
Electrolyte" that "liquefies under pressure, enabling
several safety and performance benefits," including a
wider operational temperature range of -60°C to 60°C.
Meanwhile, Korean company LG Chem is developing new
electrode chemistry and architectures with a view to
improve charging times and temperature performance.
Tesla is also trying to develop battery technology,
though its next-gen 4680 cells are proving difficult to
mass produce.
Tales like these remind us that it's still early days
for EV battery tech. It may take years for the
necessary improvements to come online but until then,
the answer is simply not to drive during a deep freeze.

I think EVs, or at least the current technology of EVs, is on par with a 8 track
player. They were cool, for about a blink of an eye. Before them we had vinyl
for years, and after them we had cassettes, and cds, and now it's just a
digital file. But 8 tracks.. man they were cool.. until they weren't.
I think EVs, as they are currently constructed, are a waste of time. We, the
planet, doesn't have enough raw materials to convert all our transportation
needs to them, and the vehicles that are already made are a nightmare.
They're made of toxic chemicals that once ignited burn so hot and can't be
put out. Literally, you run the risk they'll burn your house down if you charge
them in an attached garage..
They don't charge in the cold. But even in reasonable climate they are not
efficient enough to do more than a reasonably short commute. Otherwise
the user needs to have a reason for long layovers at charging stations, if
they can be found.
But it's the toxic chemicals that seal the deal for me.. why would I buy one
of those? And to boot, they're deathtraps as well. Look at the stats, EV
drivers get in way more accidents than their gas counterparts. I could go
on.. but I suspect they are already on their way out the door.
Not to say we don't need to replace fossil fuels.. but that the current
alternative isn't up to the task, and falls far short of what's going to come
around the corner.. and not that I know what that is.. just that gut feeling
what we're doing today isn't it.
And besides, I wouldn't give Elon a cent..

yep, you got it ... and the automakers were give tax
incentives to invest in production of them and got
burned ... and still the UAW (not the rank and file)
endorses Biden ... just today ... he came to their
strike ... but they would not have to strike if they had
not gotten burned by his policy ... people don't think a
lot ... or so it seems
