Accidental cold soak -7

[Heliian]

110v is for emergency use and won't do anything for temps, it's a trickle charger. The lightning won't charge over 1.2ish on 110v, no matter the evse or current available.

You need 240v to keep it warm and charged and preconditioned.

I've run my fcsp for 2 years at 48a and it's fantastic.

Your other problem is letting it get down to 16% soc and cold soaking it. The 110v charge will do about 1% per hour on a good day so even if your evse was plugged in and working for 12hrs, you'd still be low soc, low temp and low power available.

As I mentioned in my original posting, I had just gotten home from a long road trip. Hence the state of charge. not wanting to cold soak. I plugged it in to 110 since I don’t have 220 at the house. I didn’t need it to charge at all. I believe I’ve said multiple times I wasn’t looking to charge. Maybe the full picture next time….

By the way, my mobile connector charges at 1.3 kW even when it’s 5° out this morning.

Ah, I see.

It's not really well documented or talked about but 110v does nothing except charge.

Your life will improve greatly with 220v.

I have to wonder if that's chemically safe at such a low temp, possibly the pack temperature was warm enough from the recent drive when you parked.

As far as the chemistry, I don’t know. got me worried a little, but one would think that Ford has taken all of this into consideration, especially with a large portion of their consumers in the north.

Actually, it wasn’t from a recent drive. Plugged it into the 110 when I got home again last night but before doing so I set my destination charge level for home to 50% and made sure I was charged above that point when I got there. That way when I plugged it in it actually didn’t try to charge at all. The lights just turned blue and that was it. This morning when I woke up, though, I hit the start charge button and adjusted it up to 60 percent to see what would happen.

My battery was maybe an 8th inch of way from the centerline and the motors were ready to go. So it appears to me that it was conditioning with the 110 although others have said it won’t. I don’t know, this is all a learning experience at this point my first winter with it.

Its more likely that the problem here is the poor mobile EVSE. While the slower charging rate may not be able to keep up, it should still be supplying power.

THIS... has been my experience. Ford's mobile charger would not work for more than a couple minutes in the cold. Tried my Rivian mobile connector and it worked fine, but was painfully slow (of course).

That's generally a cold battery. You will see less power restriction at a higher soc. When you are plugged in to 220v the temp will be on the line, when you set a departure time it will heat the battery further to optimize range but it's still on the line.
I wish it would heat on 110v as then I could keep it warm while at work. But it doesn't.

Yeah, that’s silly especially if you have it plugged in, but not charging. Maybe a software update could address this……@Ford???

or just use battery power to maintain a safe temperature! here in the frozen north there are plenty of times I will be parking this for 5 to 6 sometimes 8 hours in temps well below -20. With no power in sight, What happens then??

In the "why waste $500 if you don't have to" department: If your vehicle is still under warranty and the dealer isn't completely fly by night, you might be able to get that mobile connector replaced. I had an orange-light situation which took two trips to the dealer and some data to resolve; the thing would only fail after working OK for a while. But once the problem was made clear, I had a new one within two days. Yours seems like an obvious fail which would be visible right away. It's useful to keep the portable charger in the frunk for when...situations occur.

Hope that 240V box works as advertised right away; it will definitely make your trucking life better when it does.

Not much.

It happens but hasn't been a problem. I've cold soaked mine once for 3 days at - 25degc, no issues. I also sit at work for 8 hours a day in the winter with no issues. In the winter I stay plugged in at home and have a departure time set every morning. The truck and battery are warm to start the day.
