High Temperatures - Should I plug in based on message on IPC?

[DevSecOps]

Charging schedule only applies to L1 and L2.
DCFC will cool the battery while charging for sure.

Yeah so it sounds like only "if actively charging". I wonder if it will when already at the target charge, but still within schedule.

Still haven’t seen this in Florida, curious what the temp it usually decides to activate this

I don't think it activates at a specific temp but I really need some more data to make that claim with more certainty. My previous Ford BEV would display that message at 97F ambient every time like clockwork. This car appears to have a delta between underhood and ambient and that seems to trigger the message. That delta seems like 10-15F. I will watch it a little closer this summer and see what I find.

You’ll also get a message to plug in when the temps are very low.
In both cases, plug in if you can. If you can’t, well, you can’t. Don’t overthink it.

Agree.

Usually triggers between 105 and 110 here in the desert.

Agree.

So then you could follow the advise of the IPC, but if you're outside your charge schedule, it won't even manage the thermals of the battery?!? I guess that's good, but I wouldn't think the power draw would be that exorbitant.

I don't really understand what Ford is thinking on their HVB cooling strategy. They don't allow HVB cooling when remote starting so that is quite unfortunate. They don't allow HVB cooling while parked off plug, which is an oversight now that we have a gigantic battery pack. They do allow HVB cooling when parked on plug but only inside the charge schedule, which is just plain stupid. No way to sugar coat it.

You can get around that last issue by changing your charge schedule when you park so the current time is inside your schedule. If you want the car to cool the battery but NOT charge.....then also lower your charge limit to something lower than existing. I do this every day during the summer. Not ideal, but it's the only reasonable work around that I know of. (thanks to @macchiaz-o for the tip.)

On L1 and L2, yes.
On DCFC, then it won't. At least, I don't expect it will I have never DCFC'd to 100% and even if I did, I wouldn't leave it parked there afterwards.

Thanks all for the help! I will do as the car says, if possible. I will also put back the limit to 90%. I think Ford can 1. get this HVBJB issues resolved so we don't guess around how best to charge and 2. make it a bit more seamless for regular users as they start buying EVs.

With that said, it's super hot here today (but not southwest hot). it was up in the 90s, but the inside center console said temp was 112 at one point - not sure where they are measuring that (but car was in the sun - i don't have a garage).

It had been charging and I had unplugged and then had to run to the store a mile away. Perhaps it was measuring the battery temp. I don't have a charge schedule since I can charge any time in my town for low rates.

Thanks all!

I would still recommend setting a charge schedule (from like 10PM-8AM every day) which is better for the pack than charging right away. This will allow it to cool down before charging, and will be active cooled if necessary. Ambient temps are also cooler at night which reduces the cooling load. You should also set a departure time if you leave on regular schedule each day.

That's exactly what it is measuring, the battery temp. It could care less what the interior temp in the car is.

Are you talking about this temp reading?

The sensor for that display is located under the hood, below the tub in the flow of the air coming from the radiator.

For those that are curious.....
Here is what FordPass looks like when the car is cooling the HVB without charging. It will say Preparing for Drive.

Here is what it looks like when the car is preconditioning the cabin for a departure time.

yeah that one. It was quite hot today but not that hot. It was fine on my next drive so it should be good now.

So here’s my dilemma. Since moving Maggie and Ellie to the desert 9 days ago, I’ve seen the message a half dozen times. My challenge is the garage at our new place lacks proper ventilation (something I will likely be fixing with an A/C unit for the garage). Plugging in to cool the battery is only going to exacerbate the heat problem. When this triggers the driveway is not really any cooler sitting in the midday sun. To say nothing of baking dust into the paint. My only recourse thus far is to limit day time driving. Did not properly anticipate this condition.

Hoping I’m not doing lasting damage to my battery.

This is what I'm saying. And here we have someone in New York getting it. Conspiracy!

Well…… NY and a lot of the country get higher temps in the summer than Florida.

It rarely gets over 92 here (Tampa Bay). Gotta love that afternoon sea breeze and summer showers. Highs this week are 86-91.

Just looked up NYC today….. hit 94 degrees! Yuck!

I think MME has 2 or 3 ambient temperature sensors. Car Scanner app shows three different values for ambient temperature, one is often much higher than two others (and way hotter than real ambient air).

What do I need to pull the battery temp value(s)? Lots of discussions elsewhere on not charging when battery hot from day a long trip, but yesterday I just guessed let the car sit for five hours.

People are overthinking this.

If the car wants to cool, it will display a message on the dashboard. If it doesn't, then it doesn't want to cool.

If it displays the message, and you aren't plugged in and can't plugged in, the car will be just fine.

I'm in the NY area and had the car sitting outside in direct sun for a few hours.

Ironically, my external temp said exactly 107 when I turned the car on too... wonder if it's a max setting?

I've got black interior, so I remote started the car (not plugged in) to pump some AC.... I can say, the damn thing sounded like an airplane - never heard the car so loud ever!

Even though it wasn't plugged in, i'm curious if it was doing additional cooling based on how loud it was
