When you can, just leave the car plugged in if it’s cold outside. It will keep the battery just above freezing. For the most part this is more than ‘good enough’. Heating it right up to 15C (which is what departure times do) is not really necessary unless fast charging and really is just a waste of power.

if you then drive it the battery will warm up a little bit as you drive. And when you park it (if unplugged) the battery pack will slowly drop. Unless it’s very cold the pack won’t get that cold that fast.

So, in short, I recommend plugging in when possible and just hit the climate start 10 mins or so before I leave.
it can get quite cold in Colorado and my garage faces North. I greatly enjoy PaaK and turning on climate before I leave from any location. I only use departure feature when I am taking a long trip on a cold day and I was plugged in overnight. Simple and effective for Us.

Accessory and on are different.

On energizes the 12v bus with the main battery immediately, maintaining 14.4v regardless of 12v battery state.

Accessory energizes the 12v bus with the lvb and energizes the main battery only to top up the lvb. The bus volts will be lower and power available will lower, but it is more efficient.

This is logical. It also makes it likely that hvb heating would kick in only when 'on'.

This behavior is covered under the thread about adding an inverter to the 12v bus.

Not sure why you are spending so many words trying to explain to me something it seems i know about. There is a difference, it has been covered in other threads, and my question is reasonable.

Looks like i will just measure it myself, the amount of power draw for the hbv heater is exposed as a parameter over obd2, i just thought someone else might know.
I spend the words because you seem incapable of understanding them. I said if you think it's reasonable then explain why other EVs get away without it. Instead you, AGAIN, explained how it's doing what it does now instead of explaining why it needs to be that way, since you understand it all so well.

I am essentially asking you for what purpose someone might put money away in their savings account instead of keeping it in their checking account, and you response is consistently to try and explain how checking accounts work. I didn't ask and don't need the information and you are missing the point of the conversation entirely, and it's wild that you still are.

Just because you believe it does two different things doesn't mean there isn't a better way of the car operating where it just does what it needs to when it detects a driver, like with a Tesla or Rivian. That is all I am trying to get you to realize but man you just go in a different direction every time.

I am still looking for the answer of whether starting the vehicle (using the start button in the car) on shore power in park engages the hvb warming function.

Then i am happy to delete my question and hopefully the thread.
Do the scientific thing and get an OBD reader, they are handy to have, and set a departure time and monitor the HVB temps when it triggers.

Then the next day or when conditions are similar, start the car while plugged in to the EVSE and watch the HVB temps.

In the time this thread has been open this could have been solved.

Just to clarify, PAAK isn’t required to remotely turn on climate.

Thanks ! I recall I can go to car , turn on climate and leave and lock car…not convenient for my use. I have used that if dog is left in car with a sign. And yes I could go to car , if not plugged in and set departure time and it will set climate on at the scheduled time , no battery preconditioning as car is not plugged in to a level 2 charger.
With PAAK I can turn on seat and wheel and defroster easily.from anywhere.

what ever works for you

You're not understanding.

PaaK is Phone As A Key. In other words, the phone functions like a key.

What you are referring to is FordPass, an APPLICATION on your phone that allows you to remotely do some things, including a climate start. You are NOT using PaaK to turn on seat, wheel, defroster. You are using FORDPASS.

You are correct. For my 2023 GTPE PaaK will only start the car when FordPass is open. So for us FordPass includes PaaK.
I presume you could use FordPass application to unlock, lock, set climate and all other functions. But then you must also carry your Fob to start the car.
A personal choice for sure. For us FordPass IS PaaK as the FordPass application must be open on our

For my 2023 GTPE I must have the FordPass open on iOS to start the car. So for practical usage FordPass application is PaaK for us.
FordPass includes PaaK for usage. The car will also not unlock automatically when walking up to car with out FordPass open.

I presume some owners may use FordPass and also carry their key fob. personal choice ….
