Battery heating & cooling in 2023: Parked unplugged

[GarageWarrior2023]

No. I've not set a departure time up like that even though one could. When unplugged it should only heat/cool the cabin. If I've set the cabin to OFF then it should basically do nothing when unplugged.

I want the cabin conditioned either with shore power or battery power for my departure times.

Yes I would agree, so far that's been the predominant statement about departure times and how they work plugged in or unplugged.

I agree with that. and I think I'm going to create an account on that forum to probe that user. because you're 100% correct. this person makes that claim, maybe they have proof?

Okay, I've queried that forum user. let's see if he can generate any proof of the claim. I'll report back here once I get a reply.

Who said that it does? The proof is that many people leave their cars out in very cold or very hot weather and have no parasitic drain on the battery. If active heating or cooling was occurring, the battery SOC would go down.

By the way, the owner's manual basically says that some things may not work right when it's very cold:

good general disclaimer on their part. that covers a lot of stuff in a simple statement.

That’s already a feature in the departure time menu in FordPass, I don’t get the issue.

No issue. Just saying I would not set a departure time with the cabin temperature set to off. I want heating or cooling.

so that poster states the same as everyone else in this thread so far and now says that when unplugged it does nothing for battery temperature maintenance.

Well so far no evidence that this vehicle protects the battery when parked unplugged......this seems like a MASSIVE oversight?

You could try calling Ford Canada and ask them what they recommend. Not like you’re the first one to have that question…

100% agree and on it. I'm starting by working with my dealership for a line of communication to get a definitive answer from Ford on how the system operates. From there I can pose follow-up questions.

Good luck - most dealers have no clue about these things but you might get lucky.

We'll see how it goes. the dealership itself will most likely know nothing, I have to rely on them to have a contact at Ford that's an engineer or similar to bounce this off of for a real answer, that's what I'm hoping for.....but not getting my hopes up too high.

Trust me Im NOT trying to be the "there's already a thread about that " guy but just figured you might get a faster answer from the horses mouth as it were

have you tried this unplugged? it's an interesting query.

The departure time when unplugged is exactly the same thing as a remote start, so it will only heat the cabin, not the battery.

I've tested these things myself and did not see any battery temp increase after doing an unplugged departure time.

I think the poster on the other forum assumed the battery was warming up because something was happening, but didn't actually verify with battery temps. A lot of people assume the battery gets warmed up with a remote start, but it does not.

FYI I'm the person that has probably done the most testing of this stuff with my 2022. It's possible 2023s have some slight differences (particularly with the LFP battery), but I would expect things to mostly be the same. I suggest reading though my winter topics if you are new:

I wish Ford wasn’t so ridiculously conservative or just gave us the option to take better care of our car.

Thanks for posting the link. This is awesome! I'll definitely browse this and post my questions here.

Thanks Mach-Lee, you had answered questions a while back I had posted about how the departure time preconditioning worked as well as how it behaved in relation to 120v charging. these posts had answered all my questions in the EXACT level of detail I was looking for. I really appreciate all the testing you have done and the time you spend compiling all the data for everyone in this forum.
