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.
