Are there long-term benefits for preconditioning?

[MoonRiver]

Agree with you on that 100%.

There is no reason to set a departure time (i.e. precondition the battery) if you don't need the range. You can stop wasting money.

I set my departure time strictly for presetting the cabin temperature. Not much to do for the battery here in AZ, pretty optimal already most days! But is nice in the summer not to have to use oven mitts for the steering wheel, even though it is garaged... LOL

What do you pay per KWh there? We have off and on peak here. Following it they adjust the add on costs. It really does not matter when or how much we use it always comes down to and average 0.16/KWh.
Math edit

Wow, I guess I have it really good here in AZ, as my electricity provider (Salt River Project) has an EV time of use rate from 11p to 5a that is $0.0575 pkWh in the winter, and $0.0614 in the summer, so an average of $0.05945.
The wife has a 90 mile round trip commute, and is averaging 3.3 mpkWh religiously (way lower when I drive it!), so the average cost is $1.62 a day. We use the departure time so the cabin is cool or warm, and I can't imagine that costs me more than a few cents a day, and I lean towards battery conditioning having some positive effect on longevity, I can't see how it can really hurt.

PSE&G in NJ has an excellent discount program off of the regular rate of $.185/kwh for EV off peak charging:

Yeah, no. I got solar instead.

Any idea how many kWh are needed to precondition the battery? The outdoor temperature in the morning is about 25F. I commute 33 miles to work each way.

Last I tested it ran the heater for about 15 minutes to warm the battery, then another 15 to warm the cabin. Total was probably 2-3kwh. Heater wasn’t running the max 6 kw, and my garage temp was around 30F.

This morning the outside temp was -3F. Garage temp is 29F, and car is in the garage.

I had a departure time set and to set the cabin to warm. My Emporia charger used 8.49 kWh in 1 hour and 4 minutes.

Edit: I should state I didn't end up driving this morning, so that 1 hour and 4 minutes includes 15 minutes of pulling roughly 20 amps after my set departure time. I assume this was just keeping the cabin warm.

So it took 45 minutes to precondition the battery and warm the cabin for my departure time at 29F.

Many thanks for all your input/comments.

Does anyone know if you can precondition the battery without conditioning the cabin? In the Cool-Medium-Warm “Cabin Comfort” menu you can also set to Off. Not clear if that is telling it to not condition the cabin or if it’s turning off the whole preconditioning. I have a feeling it is everything because it grays out the time. But not sure why you wouldn’t just delete the time if you wanted it turned off.

Based on a new State of Charge video with a Ford engineer, he said a preconditioned battery only loses like 1 degree per hour so it’s worth doing every morning no matter your driving plans. If that’s the case I’d like to precondition the battery, but not waste extra energy on the cabin and just remote start a few minutes before if I go somewhere.

I know I can set to Cool, but just wondered if Off works. Tested it once and it didn’t appear to trigger my charger, but it could have been that the battery was still warm enough.

Selecting off for Cabin Temperature means exactly that. Off. No cabin conditioning. It is not everything. Set a time, then a day, then set off.

And Darren Palmer is VP of Electric Vehicles, not "a Ford engineer"...

Yes, OFF works, I've tested it: https://www.macheforum.com/site/thr...her-testing-taking-requests.24393/post-567699

However there may sometimes be issues with the FordPass server sending the command to your Mach-E. Seems like a server glitch or a lack of AT&T LTE coverage could be to blame.

I am under the impression that simply keeping the car plugged in will keep the battery from getting dangerously cold. That’s why we get the “It’s cold outside, plug me in.” Message.
If that’s true, just being plugged in is as good or better than preconditioning.

I also didn’t think it was possible to completely disable regen?

can Someone send a screenshot of this it’s cold outside plug me in message? I recently disabled PAAK but I haven’t seen any messages in the app.

I’ve only seen it in the car, not the app.

The battery is warrantied for eight years. Not sure I much point in babying it even more than Ford already does, since it's in Ford's best interest to extend the battery life for you.

That's alright if you plan on getting rid of the car between 3-8 years, but for those looking to keep this car for 20+ ... It's in your best interest to have a healthier 20yr old battery.

Imagine bringing it from 2% to 100% via fast charging for 8yrs because the battery is fully warrantied that entire time and then having a shot battery at 12yrs vs doing all the things suggested for battery longevity and not having much degradation after 18yrs.

I agree - it is a personal choice/comfort thing. Most of us (especially the working stiffs among us) travel by car locally.
It would be better if it could work via FordPass (probably a pipe dream).
It's your thing, do what you want to do.
