[EVDL] EVLN: Dead Teslas in Chicago
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 ... https://electrek.co/2024/01/16/dead-tesla-cars-pile-up-chicago-superchargers- extreme-cold/ or https://cntp.me/ZF6ntkE - "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.] https://www.npr.org/2024/01/16/1224913698/teslas-chicago-charging-extreme- cold or https://cntp.me/xlCSYgo - 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. ... https://www.pcmag.com/news/dont-buy-a-tesla-chicagos-ev-drivers-struggle- with-sub-zero-temperatures or https://cntp.me/lJQ6r4T David Roden, EVDL moderator & general lackey To reach me, don't reply to this message; I won't get it.

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)
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)
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)
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: (Picture Link https://ingineerix.com/pic/?lg-heat-pump-idu ) On Tue, Jan 16, 2024 at 4:46 PM Haudy Kazemi via EV wrote: > That's pretty neat.

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)
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)
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 Sent from my iPhone On Jan 16, 2024, at 6:27 PM, (-Phil-) wrote: 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!). On Mon, Jan 15, 2024 at 5:58 PM Mark E.

Re: [EVDL] Running a 1-ton mini-split (12A, 120V) from an EV with 1500W (12V@120A inverter)
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!). On Mon, Jan 15, 2024 at 5:58 PM Mark E.

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