[EVDL] EVLN: Dead Teslas in Chicago

2024-01-16 Thread EV List Lackey via EV
Teslas are lined up in extreme cold, waiting for Chicago Supercharger 
stations, where charging is very slow.  Apparently some drivers have run out 
of charge trying to stay warm while waiting for a turn and had to call for a 
tow.

Not a big surprise at ~-20C I suppose, but I don't recall reading of such 
problems in the Nordic countries.  Maybe those owners are more likely to be 
educated about their vehicles, and to follow Tesla's cold weather 
recommendations.

Not much is said about other EV brands, but there's no reason I can think of 
that Teslas should have any more cold weather charging problems than Bolts,  
 Leaves, Kias, et cetera.

Dead Tesla cars pile up at Chicago Superchargers in extreme cold

A bunch of Tesla vehicles were unable to charge at Supercharger stations 
across Chicago amid an extreme cold wave. ...

Chicago is seeing an extreme cold wave at the moment. Yesterday, the windy 
city had a temperature of 2F (-19C) that felt like- 20F (-29C) after the 
wind factor.

These extreme temperatures have been blamed for issues at Tesla Supercharger 
stations across the city. ...

Most Superchargers are marked as all-in-use with wait times ...

"I've been here for over five hours at this point and I still have not 
gotten to charge my car," Tesla driver Brandon Welbourne told CBS News 
Chicago, as car horns blared nearby. "A charge that should take 45 minutes 
is taking two hours." ...

Tesla has tips for drivers in the cold ... 

maintaining a charge of at least 20% ... 

warm[ing] the battery. ... 

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 ...

"Always connect to an external, low voltage power supply before opening a 
door when the vehicle has no power," Tesla says, "to avoid breaking a 
window." [Yikes.  I take it that Teslas have no hard-key backup.]

Most news sources are reporting it straight and without bias.  A few are 
pushing the negatives.  Thanks guys.  Example:

'Don't Buy a Tesla': Chicago's EV Drivers Struggle With Sub-Zero 
Temperatures

With temperatures consistently below zero in Chicago, electric vehicle 
drivers there have struggled to keep their EVs charged over the past few 
days. ...

"I've never seen it like this before," says one driver on TikTok as she 
scrolls through her Tesla app, which shows 20- to 30-minute wait times at 
most Superchargers near her. "Don't get a Tesla," she says, unless you live 
in a warm climate. ...

When PCMag took a Tesla Model 3 on a day trip around Chicago in January 
2023, it achieved less than 100 miles of the advertised range and could not 
go more than an hour and a half without charging. ...

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

2024-01-16 Thread (-Phil-) via EV
My backup is a complete 85kWh pack from a 2014 Tesla Model S which is
hooked to a 15kW split-phase inverter made by Bel (out of production), but
with some crafty software on my controller I can go open my main breaker on
the meter and turn on that system.  It fires up the whole hose, then when
(if) the sun comes out, my SMA 7.7kW grid-tie solar inverter "thinks" that
the Bel inverter is the grid and begins pushing back into the Tesla
battery.   When the Tesla pack hits 85% SoC, my controller "burps" the AC
by switching to 50hz for one cycle, then back to 60hz.  This causes the SMA
to disconnect and wait 5 minutes.  It will keep repeating this until the
SoC is below 85%.   The controller is based on an ESP32 so it has a web
page and will send out low SoC warnings to my phone.   My house is
heated/cooled by a LG multi-zone mini-split heat pump, so it runs fine on
the off-grid system.   I also still have the house's original natural gas
furnace if needed, but I normally don't run it.

I told myself I'd automate this with a big 250A contactor on the main AC
input, but it's a lot of expense/work and the power isn't out here but
maybe a few times a year, and I can handle the manual switchover when it's
needed.   I have all my critical gear on a 2kVa off-line UPS hooked to a
48v 280Ah LFP bank, so that will stay up anyway.

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

2024-01-16 Thread Phil Hochstetler via EV
Portland Oregon area just experienced a wind/cold event that took away
power from 150,000+.
I have a new in the box 7500 watt tri-fuel generator but had not set it up
yet (of course).
My model 3 was charged, but not setup with an inverter yet due to lack of
motivation, but our Rav4 Prime
had a full tank of gas and the 1500 watt built-in inverter that runs off
the high voltage pack.
I wired a short cord on the furnace (NG furnace) so we had heat as it was
12F out and ran a cord into the house
under the garage door so we could run a light or two and the 2 burner
countertop induction stove and refrigerator.
Pretty sweet.  In on mode (with doors locked with key), the rav4 would turn
on when the battery got low and recharge the battery.
After 24 hours, it used 1/8 tank of gas but we were warm and had
light/food.  I went out and got 10 gal of gas to fire up the generator
and the power came on before I got back.  Still fun.

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

2024-01-16 Thread (-Phil-) via EV
It was a Chinese-made Pioneer, I don't recall the model, but it was the
larger of the two offered at the time (about 10 years ago), the smaller one
had an AC fan, and the larger one was BLDC.   It had a PFC boost function
to about 400VDC.   It was hooked to an 85kWh 16 module pack.   Since the
max voltage of this pack was inline with the PFC boost bus, it all worked
perfectly.  I just bypassed the PFC stage.

Even without PFC, any 240v appliance has to be rated to handle +/- 10%, so
that's 264VAC or about 350VDC when dumped into a full bridge at the filter
capacitor.   Chances are the limit is going to be the voltage rating on
those filter caps.  Usually 400VDC, though some have better headroom at
450VDC.   Some equipment targeted for industrial use is rated for 277VAC
(one wye leg of 480VAC), in which case it's designed to see up to 305VAC
which works out to about 405VDC.

If you are wanting to do this the best way is to locate the service manuals
for various units you are interested in, and then look at the wiring
diagram.  It's usually really obvious which uses AC fan motors.
For instance, here's the wiring for the indoor unit on the LG unit I have
in my shop, as you can see, it's fully capable of DC except for the
built-in condensate pump, so you'd have to do something about that:

Yes, I tried to get worst case with heat mode at 86F with the outside temp at 
17F, got 6.5A.  In cool mode with less differential I measured 5.1A

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

2024-01-16 Thread Haudy Kazemi via EV
That's pretty neat. Reminds me of what people have done with direct ties to
Prius packs (PriUPS).

Can you share any specific mini split models that you have seen, or heard
of, being used this way?

Which Tesla pack? Was this with a 350v DC (14 module) or 400v DC Tesla pack
(16 module) legacy Model S/X pack or some other Tesla pack? My napkin math
says the 350v DC packs have a better chance at compatibility.

Was the pack still in a car? If so, did you run into any problems with the
car software making things harder than necessary?

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

2024-01-16 Thread Mark Hanson via EV
Thanks Phil
Sounds like a project :-)
I also have a Schneider SW4024 that powers the well pump and fridge during a 
power outage but the LiFePO4 batts are only 7KWh tied to 1200W solar panels and 
a Bergey XL-1 (1KW rated) but at night in a storm probably only get 5KWh out.  
I just measured the 2020 EnergyStar 1ton heat pump at 6.5A 120V (about 26Seer) 
which is better than I thought.  I have a similar Klimaire that’s 2014 and 
draws 12A 120V doing the same job (about 17seer).  Maybe just put another log 
on the fire :-)
Stay warm ,
Mark

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)

2024-01-16 Thread (-Phil-) via EV
I have successfully hooked a Mini-Split (240v) up to a Tesla pack
directly.   You have to perform an analysis to make sure it can support DC,
and there are only a few that can, as most of the indoor-unit fans use AC
motors, but there are a few that use BLDC.   You would not be able to do
this with a 120v unit unless it's internally using a capacitor doubler (I
have seen a few that do this!).

Re: [EVDL] EV Digest, Vol 135, Issue 10

2024-01-16 Thread Randall Prentice via EV
I wonder if you have seen :-
Youtube "The EASIEST way to connect used EV packs to grid!" From Dala.
He shows the steps in getting the CHAdeMO 400V and then connecting to inverter.

YT   /watch?v=XHZWGLzT7gg

Regards
Randall

I was reading Otmar's inverter connection to a Tesla-3 and looks like Tesla 
makes it really difficult to run a 1500W 12V inverter from their EVs.  My Bolt 
shows 130A available from its DC-DC converter, just clamp the Harbor Fright 
inverter (have 1500W with 200A inline breaker, short aligator clamps) on the 
battery & the Leaf appears to be rated about 90A, so probably not
enough to run my mini-split at 12A, 120V.   Presently if the power goes out
- I just put another log in my wood stove, but thinking it would be nice to run 
one of my EV's as the 64KWH power source incase the power goes out for awhile.  
I have a Bergey wind turbine on LiFePO4 7KWH batteries, but that would only 
last a few hours running the Pioneer mini-split.  Has anyone done this 
successfully?  The Bolt has to be *on* in neutral or park with the key in to 
keep the DC-DC converter alive.  Would rather not have a Kerosun for backup...
