Cold Cold Weather tips

Unfortunately I don't use a scanner to monitor what the temps actually are in the cold soaked pack during charging process, but I have to assume that at least 25% of the energy is initially going to the warming process, the balance is going to the battery pack.

Assuming your highest concern is to not 'force' a charge while the battery is below freezing, without putting miles on the truck & using a faux destination to a DCFC to trick the BMS to commence battery warming, stationary in the driveway process

You could also try the following

• Edit the location based charging profile (in the truck) to 50% (assuming you're current SOC is above this value) that should inhibit charging for the next step, 50% is the minimum.
• Define a departure time that commences around the time you intend to do some charging, that will execute 30-60 minutes prior to faux leave time, warming up the battery.
• Once the departure time has lapsed, go out to the truck, edit the location based charging limit to whatever value you desire, let the charging proceed.
• This sequence of events should get the pack temps up, and it'll warm further from the charging activity.

You could do all of this from the comfort of your easy chair IF you turn on connected options......

Very Clear and helpful. Thank you for taking the time.

‘This is a viable option when SOC is bellow 50% and I have to go out for something anyway. I just went out for 4 min and put a fast charger in Ford Navigation. OBD II shows battery temp to the tenth but it did not move. When you do this, does it take a long time to notice a difference? Or I am missing a step? I will go for a longer drive this afternoon for a second test.

I’ve not noticed my battery warming when navigated to a FC myself. Gauge stays the same at least, I don’t have a ODB.

I don't use a OBD2 tool, but the process is designed to work for ~20 minutes / 20 miles out from a DCFC, you need to give it a good 20 minute drive to see the impact, also the DCFC needs to be high capacity, IIRC 150KW or faster.

I guess that explains why it hasn’t done anything for me. The closest fast charger for me that’s over 120 is over 150 miles away.

Earlier this morning it was 6° at dawn, my available power was 100% at a 90% SOC, the heating of the pack from the Sunday afternoon charge barely held up overnight as we headed out to the grocery store, MAN was it packed at 6:50 am, by the time we were done shopping and a quick stop at the ATM, and returned to the house, the available energy dropped to 96%. temp gauge was halfway below mid-point

Put the groceries away, then headed out to breakfast & coffee, then back to the house ~45 minutes more cold soaking and available energy had dropped to 91%, the truck sat in the driveway until 1300 hrs, it was still COLD, but warmed up to 26°, the available energy was still at 91%, gauge was still low.

The lunch trip was short, I programmed an EA that was only 6 miles away, slow local roads with Christmas shoppers slowed the trip to 20 minutes, by the time we got to our destination, the available power had not risen much and the battery temperature gauge was still below centerline.

I let the truck continue to idle with the DCFC destination still active, turned off the 30 minute timer, had lunch and returned to the truck which now showed the gauge slightly closer to midpoint and the available power to the motors was up to 96% an hour had elapsed to get the temps higher.
