Probably best to have the app actually load first.

I can't find the photo right now but I remember in one of the Ultium vehicles there was a warning message that would pop up about Reduced Charging performance with HVAC on. Also with the size of the Silverado Battery that's a lot of thermal mass/energy to dissipate.

I remember that too - I think it was one of Kyle's. This is kind of the opposite, though, with the cabin AC shutting off to prioritize the battery. My memory is playing it usual tricks but I seem to remember one of the EV trucks had 2 heat pumps just for this reason. Am I misremembering? If not, which one was it?

IIRC, Ford Lightning extended range w/ the max towing capacity.I think the second compressor was dedicated to just pack cooling.

Ironically, one of the worst charging EV pickups (slow but consistent curve). At least it doesn't have thermal issues.

Seems to me cooling should be sized large enough to meet cabin and pack demands.

When you get north of 100 that becomes a challenge.

Good reason to avoid dark colors and interiors.

I’ve never heard this complaint with other EVs, and have no experience fast charging, is this a common issue? I’ve never heard Kyle talking about it although he always seems to talk up Tesla thermal system and knocks the rivian. If I lived in a southern state and was fast charging regularly this would be a major consideration.

Kyle is always focused on charging optimization so he turns of heating/cooling of the cabin, seats and steering wheel.

Frankly, he cracks me up. It doesn't seem to matter if it is 10 degrees outside or 100 degrees, he wears the same hoodie/sweatshirt and shorts.

You've seen him wear shorts! Usually long pants in the desert!

I'd like to start a thread for first-hand reports of real-world towing.

First towing trip wrap-up

• 625 miles roundtrip
• 7,500 ft elevation change each way
• Load: Towing about 1,200 lbs, 3 adults (510 lbs), gear, food, drinks, and one small dog
• 2 charge stops, one each way, about 30 minutes each, at an EA 350v, but we overcharged because we were sitting down to eat.
• Charged with cabin AC on in 100° + temps
• EA still sucks!
• Average efficiency 1.5 miles/kW
• Really could have used the tonneau with the daily mountain thunderstorms
• Got the truck really dirty, inside and out. Looks like a REAL truck now.
• Turned a lot of heads, but not like a CT does. People who don't know EVs didn't notice us, but people who do were very interested.
• Left home w/ 96% SOC arrived home with 13% SOC

Side note: I ordered the rubber floor mats as soon as I got home. We got them free with our GM points!

Sorry your charge experience sucked. An all too-common experience, unfortunately. sailboats can be easy tows, relatively speaking. Good aero and hydrodynamic shapes reduce drag. Are you going to the High Sierra regatta, by chance? If so, what are you sailing? I used to race a C-15, then a Laser and a Catalina 22 up here at Whiskeytown and other local lakes. Never made it to a High Sierra regatta.

OMG! Yes, we were at High Sierra Regatta, Huntington Lake, CA. Sorry for the late reply, not much cell up there. We sail the first weekend of High Sierra, Daysailer class. I have a Laser and I crewed for years on a C-22. We missed Whiskeytown this year for the birth of grandbaby #3, but should be there next year. I bet I'd recognize you. Stop by if you are at Whiskeytown next May.

I do not think it wasn't the F-150s fault. You can't just go to the back of a numbered station and take their charging capability. And of course it's either one or the other cable.
Charging etiiquette, people

It was a weird charger. Slanted entry for a one-way parking row, as I have said. There were two cabinets. One in front one in back. So you could use either one from parking spots on either side of the cabinets. The front cabinet was labeled #1 (the one we are plugged into in the pic) and was a 350V, the cabinet closer to the parking row, was labeled #2 and was only a 150v. Each cabinet had two cables with CCS connectors. So same type, same cabinet number, but you can only use one. Kind of a waste?

Both of these cables are cabinet #1. It is not a case where they share power and split the voltage if two cars plug in. We had to back in to get to the 350v because the other cabinet, at the top of the photo, was 150v.

Something caused our charge session to stop after just a couple of minutes, when we walked the 3 blocks back from food, IN MEGA HEAT, to check on it, the Ford was plugged into our cabinet, using that white connector, (we were still plugged into the gray one) the Ford was charging just fine.
[edit] Maybe our session had terminated due to an error, so the Ford thought we were done?

I didn’t think the AC worked while charging in this truck. Please don’t trust the truck to keep the AC on for your dog, it’s not designed to do so and there is no way for you to check the temperature in the truck to confirm in the app like you can with a Tesla. Even with the “hack” I would not trust it, these early GM EVs are glitchy and unpredictable, the result could be tragic. The rest sounds like standard non Tesla supercharging normal kine stuff.

*Even in the Tesla I trust but verify, I check the app every 10 min to see the temperature in the car. In 110 a dog could die in 15 minutes.

I was able to get AC to work after that first attempt. It was something about being stuck in the "Guest" profile. But I checked CONSTANTLY. The second time we charged, while still hot, the sun was down. So the "Oven" effect wasn't as bad. I wish you could control cabin temp from the MyChevy app and check the temp inside.

 

[Grandma-EV]

Given the temperatures, it makes sense technically for the truck to devote cooling to the battery during the charging. However, Chevy should give us the option of keeping AC going and slowing down the charging. Not only might we need to keep pets cool, there are charge stations where there are no facilities for people to stay cool. I can just picture someone dying of heat stroke sitting in an un-airconditioned cab waiting for a crappy charger to do its deed. One lawsuit should change their minds pronto.

The Silverado's AC is beefy. I'm not sure what the battery temp was, but we were getting good charging speeds, in extreme heat, with cabin AC on.

 

[Grandma-EV]

I get a text message when my Bolt charger shuts down unexpectedly. That is the least that should happen. Should also be able to monitor interior temps all the time. Yes, we all know to be especially careful with creatures in the vehicle.

My husband started the charge on his phone and he is notorious for not noticing phone notifications. So we really don't know if EA sent him a charge interrupted notification. I just checked his MyChevy App, and he had charge notifications (charge interrupted, charge complete) turned off. Fixed that!

So, from what @nebula1701 said, the truck might have taken AC out of "auto", leaving just the fan on, to divert cooling to the battery? Hrmm, we thought it was something we had inadvertently done. It was a worse-case day... 110° out, noon, so the sun was directly overhead, no shade, and 350v charger.

And it's been said, but the app doesn't show any temps, or climate controls at all. It would be nice if it reported both cabin and battery temps.

Although "remote start" is supposed to precondition the cabin, I guess to the last setting used?

OHHH I just tried it!!!!!

1. I pressed "START" (and hold 2 sec.) in the app. Now, the button that said "START" says warming to 72°. (I guess it is cold in my garage)
2. If I press (and hold 2 sec.) that button again, now I can change the cabin temp or even turn off climate control!
3. Holding the button again, turns off the vehicle.
4. Remote start locks the vehicle too.

Well, that was hard to find! Like an Easter egg, I really need to read the manual.

You probably didn’t miss much this year. From what I heard, calling it “light air” was being generous. Hope you found fair winds for your Daysailer at Huntington. I’ve heard it is a great lake for high performance boats.

I didn't know what "all the things Tesla can change" are.

I'm wondering why the GM apps are so slow, especially for the vehicle updates and to change the charge settings. I want to say, when I owned a bolt about 6 years ago, the app worked great, better than the app for the Audi e-tron...it was slow and flaky. I liked GMs much more. I still do, but the vehicle update and to change the charge setting isn't as seamless as it should be. Sounds like Tesla's is great...definitely an improvement area for GM.

GM is aware of the app issues with Ultium vehicles, they have a lot of optimization to do. Lyriq has gotten a lot better since it was released.
