Intentional cold soak -15

[TMND]

No complaints here just curious if the motors temperature gauge is just a dummy gauge. Or possibly only registers overheating. I started up this morning and the motor is right on the line (always is -15 to 95) yet I didn’t lose a single percent of battery overnight so how is it at temp?

by the way, the only reason this was intentional is I would’ve had to move my wife’s car to charge and seeing I was almost at 90 didn’t bother

I'll take my 120F summers over -15F winter any day of the week. Good Lord man, that's cold. I'm kinda surprised you didn't lose any battery, it had to have done something overnight to keep the battery from going past the left hash mark. Very interesting.

I’m surprised it didn’t just show this on your screen:

you can only take so much off, but you can always add layers.

I agree about some energy usage. It was at 89% at midnight and 89% before I started the cabin from the app. That ran for five minutes and when I got in the truck and started, it was at 87 percent. So maybe a little

Speaking of gauge elements I don’t fully understand, what is the meaning of the energy guard not going to 100?

That’s showing you that the truck will only put out 66 percent of rated power. Cold temps and/or low soc. I see now that’s just a snippet of my original picture. battery is cold -15 degrees

As pointed out above power to motors is restricted with such low temp's

This is where being plugged in and using the using departure timer will improve output, truck will warm the battery to allow it to offer more potential energy to the motors.

Keep in mind that 66% of your full power is still a lot of power. Your 0-60 probably slows to a sluggish 5 seconds.

But he's at 87% Charge and in Raliegh (assuming North Carolina)! It definitely means that there's only 66% of power available, but doesn't it also happen when one motor isn't working? I thought I remembered that as an issue also. If I remember correctly cycling the truck on and off a few times will often reset that.

If there is a malfunction in the powertrain it could be reduced.

I saw my motors were cold the other day when I left work. It popped back up quickly tho. It was 30ish outside. Like within 5 seconds of turning the truck on the motor gauge went back up to the middle.

It's been rather chilly here in NC the past few days. At least by our standards. lol

I did another demonstration of the impact of departure timed preconditioning and if there is any spontaneous warming outside typical departure time frames.

After getting back from morning coffee run, I pulled the truck back into the cold garage outside & inside temps were around 30 degrees, not extreme, my SOC was at 54% and a projected range of 119 miles, the available power to motors was 88%, the battery gauge was down slightly, motor gauge normal.

The charging routine was curtailed to 50% to inhibit most charging energy from being sent to the HVB, though the energy is being made available at any moment the truck needs some, eg. unrestricted time frames.

I plugged in @ 10:13 am. hoping I might see some energy flow to warm up the battery, initially none, except a quick burst to confirm SOC was above set point then the FCSP clicked to standby. Then warming energy started to flow for 12 minutes at a sedate 0.6kW pace at 10:54 to 11:06

Full rate ~9 KW battery warming kicked on around 12:02 pm, ran for about 12 minutes then amperage went up to ~18 KW as if the battery OBCC was trying to top the battery, but note SOC only went up 1% during the entire process of 1.75 hours. Total energy used to condition the battery was 10.1 kWh. The official cabin conditioning ran from 12:45 to 1:00 pm, you see the cycling of the PTC around and under 4.5 KW during this phase, it appears the battery was at spec around 12:35.

12:18---------------------------------------------------------------12:20

1:00 pm

The FCSP recorded the energy consumed, {note that since I was not officially charging, there was no energy / charging report in Fordpass}. 10.1 kWh energy costing $3.40 to improve performance to the motors to 100% and to travel an extra ~15 miles. This is an investment that pays off for longer road trips, my usual driving pattern of minimal miles and local roads doesn't require daily battery preparation.

Excellent info Taxman! We've made our L2's cry the last few days (over current errors) which I suspect is that 18kw spike tripping them! Coming to a truck with an "error" charger at -30 is not my idea of a good time (nor the skin off my thumb resetting breakers).

I was particularly mean to two of the trucks this week leaving them unplugged, below is -26 (-15F), the day before was -31(-21F) and the truck limited me to 26% power. Interestingly the GOM has gotten smarter regarding cold it was giving me only 60 miles for 39% charge on ER battery lol.
