Cabin warming

[XLTTOM]

I should know this but how much of the battery is used when you are plugged in while warming up the cabin ?

Depending on what your EVSE is providing to your truck, none of the battery could be used.

It’s a level 2

You should be fine. I think the heater for the cabin is max 6kw might be wrong so someone can correct me. So on a level 2 I would think your battery would be untouched.

Thanks for the info

Initially the cabin heater can draw 8 or 9 kW, but that only lasts a few minutes. Once the cabin heat gets close to the set point it backs off and the steady state draw is more like 1-2 kW. I was watching the numbers just the other day as I was plugged into a level 2 waiting for the highway to open after a closure. Outside temp was just a couple of degrees below freezing so not super cold, but a good data point I think.

Speak for yourself!
The cold is good to visit, but not to live in IMHO!
You probably feel the same about the heat!

As other say, if you're plugged into level 2, all energy for heating will be replaced with the charging energy, the AC is converted to DC and most of it is consumed by the PTC and related systems while the truck is in climate / remote start mode.

If my battery has already reached its SOC goal, then I will see a brief spike to 17 KW [FCSP @ 80 amp setting], which is the OBCC testing the battery briefly to confirm no additional charge is needed, then the OBCC tappers back to around 9 KW about enough to feed the heating or cooling operations. About 5 minutes or so and the energy flow continues to tapper down the remainder of the time cycle if you have set a routine of 10 or 15 remote start duration in the truck settings.

Depending on outside temperatures and how high you set the requested warm value, you'll use 2 to 5 kWh of shore power energy.

Today, in 23 degree weather it toggled on off about 2.5 to 3 kW with cabin temperature set to 60 degrees.

Additional observation from this morning that could impact how shore power is used:

I've been scheduling my charging daily since the freezing weather started the past few weeks to get a firmer idea of how much overhead warming is occuring vs. weekly charging, so far it's proving to be more costly than necessary given my weekly drive routine. YMMV especially high mileage drivers.

After yesterday's' driving around I had depleted the the SOC from 90% to 74%, plugged in last night with a home based charging rule to begin charging at 5am and bring the SOC back to 90%, with no morning departure time programmed, I intended to use remote climate start ~15 minutes prior to leave time at 8am

6:30 am this morning I was looking at Fordpass active charging session data, it's looking normal, Fordpass projected 90% by 7:35 am, I looked at my Emporia log, it's also normal, logging several more kWh than Fordpass which is par for the course, recall that it only reports net energy to the battery.

7:27 am, Fordpass notified me with an alert that charging had completed, as per the most recent version 5.9.0 it's suspends the display of the details about the active charge session because the goal has been met, you'll only see the final details again from the history log AFTER you unplug.

I recently discovered that if you click the [START] charging button, that the data panel will reappear, I did that and pulled the stats for my spreadsheet, then immediately clicked [STOP] charging.

7:45 am I click the [FAN] icon to start the climate controls, truck started and warming commenced.

I look at the charging session data panel which is still displayed, but the kWh deposited does not change, well that s been the case since the SOC goal was already met, in older versions of FP this counter would continue to accrue kWh.

I look at the Emporia log, I'm NOT seeing any additional energy flowing to the truck, apparently interrupting the programmatic routines with a START/STOP button cause the OBCC to block any additional energy transfer, even for modest amounts to balance charge & draw from using the climate conditioning.

7:57 am, I see the SOC has dropped to 89%, so I clicked the [START] charging button, energy begins flowing, I let it run until we unplugged a minute or two after 8 am.

Lesson learned, DO NOT interfere with the programmed routine and supplemental energy will flow as long as your time frame limits allow energy to flow, tamper with the stop button and any remote start or departure timed conditioning will be interrupted and the battery will be drawn upon for warming routines.

Here is the post event logs:, traction energy 33 kWh, gross energy 44 kWh, losses 25% due to battery & cabin warming plus AC/DC conversion.
