Lariat ER doesn't precondition while on

[Hammick]

A couple weeks ago we stayed in Wheatland, WY and were plugged into the hotel's free destination charger for about 12 hours. Truck was on and we were running a large car fridge/freezer with the bed pro power and had the cabin heat running. I set a departure time and was surprised to find it didn't precondition.

So if the Lightning is turned on is it effectively preconditioning the entire time it's on?

It was very cold and our next destination was a DCFC in Casper, WY hence my desire to have the truck preconditioned for the 109 miles of cold interstate travel.

To precondition, the truck has to be charging, and you must set a departure time in the sync interface. In the 90 min or so ahead of the departure time, the truck will start the pre-conditioning process. Note: this is only recommended for expected cold weather long hauls. Short daily commutes don't benefit from pre-conditioning, and quite a lot of shore power is used by the process.

I do not believe the preset departure time works if the vehicle is on as you had it set. I also don't know what kind of battery management it's doing in that time either - ie, whether it keeps the battery as warm as preconditioning would make it.

How do you know it didn't precondition?

I don't think it would while the truck is OK, but I'm curious how you knew. OBD2 reader?

Ford needs to make managing the battery status more transparent. It's great that they want to hide all the EV-ness, but given the limitations of current batteries, we need better information and more control.

If you're plugged into shore power, you should be able to hit a precondition button at any time and also see the current temp of the battery at all times without being hidden behind the dummy-gauge that's always in the middle except in extreme cases.

No, it is not going to precondition for a departure time when you have already departed, i.e. the truck is on.

But your logic is flawed a bit. If you want the truck to warm the battery for charging, you need to set the charger as the next destination in the Ford Navigation. 18.6 miles from the charger (30km), it will start to warm the battery.

Just driving doesn't accomplish that. In fact, if you precondition for departure, it will warm to around 60 degrees. As you drive, the battery temp will drop. Then, as you approach the charger, it will warm if you do what I described above. While DC fast charging, temp will get to the 90s (turn off cabin heat for the first 10 minutes). Then, as you drive, it will drop.

The ForPass app tells you when departure preconditioning starts.

Not flawed. My post was about departure preconditioning. I'm well aware of charging preconditioning and use it whenever I'm headed to a DCFC (assuming it's in the NAV system).

Sorry if I sound a little defensive but I just watched one of the worst Chief's performances in many years.

Merry Xmas!

I doubt Ford engineers considered a driver wanting battery preconditioning while the truck is already on, the broad assumption is that battery condition is fine until approaching a DCFC and that the cabin state is acceptable to the driver however left, even overnight while the refrigerator is being powered by PPOB.

Your scenario is a tiny fraction of what the average user is expecting.

BTW, not rub salt in the wound, but the Pat's finally pulled off a win, SMH.

The truck will use shore power to warm the battery if it's plugged in and running.
Either through manually pushing the start button, remote start or a pre-conditioning session (essentially a remote start on timer).

He had the truck already running to run PPOB and power the portable fridge.

And in that case the battery temp will be maintained as long as it's hooked up to a charger, at least that's my experience.
Granted, I have not logged mine overnight in cold temps so perhaps that's something I'll look into as soon as we get colder temps, but at least starting it (via start button in the truck) will condition battery temp while plugged in.

You using the terms "condition" and "maintained".

Yes, when the truck is running, it will keep the battery above freezing. It will NOT condition the battery to warm temps that allow faster DC charging. That requires navigating to the charger.

This can be easily observed with an OBD adapter and Carscanner.

This is the problem.
There's too many naming conventions with similar names and functionality.

My truck, when plugged in and left "running", (no one has talked about driving yet, only plugged in) will use shore (house/charger, not battery) power to condition (heat) the battery to 60-65F.

This has been logged by OBD as I have done for the better part of a year (look up black box on this forum).

My 2016 Tesla notifies me while driving when it starts to precondition before my next Supercharging stop. Surely my 2023 Lariat ER should be able to do the same, right?

This use case [OP POST} was sitting in a parking lot over night.....................

Your Lightning gives you no clues about enroute pre-conditioning to a DCFC, Trust The Truck.
