Intentional cold soak -15

[Maxx]

I am charging now at battery temp of 39.2 (ambient 17F). Coolant heater is off and no energy is going to warming battery to higher temp. So my battery does not need to be at 60F to be charged. Not sure how low it can go without heating the battery during charging. I just know during periodical battery heating process, heater shots off when battery get to 41F. It looks like after it shots off the battery temp still may go a little higher. At those temps I get 100% power.

See Dave's post in this thread, makes sense......

Thanks. Look images bellow. my truck was plugged in and battery was at 21F. so 25 may not be low limit for Lightning as it is for Mustang.

One more piece of Info: I just juiced up from 50% SOC to 70%. At 6.5 KW (charger was giving out 7.3 KW). At ambient temp of 16F battery temp went up 7.2 degrees. I assume at your charge rate it would heat up faster. This was from 39.2F to 46.4F. Heater was not used to warm up the battery. Just the process of charging. The other thing I noticed the delivery loss was at 10% but if I recall correctly, I was losing 7% during summer.

Also look at battery Temp and Energy at the same SOC

This is when almost juicing is done:

This is before I went out for a ride and used up 20%.

Hmm, I will need to look at mine but I would swear my truck is heating the battery to 60 during charging. Mine was near freezing when I started charging.

Frankly, it's frustrating, even with the -4 today my garage was just under 40 degrees. I would prefer to not heat my battery every time I charge just for that heat to bleed off everywhere.

Thursday morning low of 10°, stimulated the Lightning to run the spontaneous battery warming at
5:13 am running until it paused for 3 minutes then resumed and finished at 5:24, only 1.2 kWh of energy consumed.

15 minutes of remote start will run from 6:40 to 6:55'ish 1.9 kWh

I manually started it at 6:40 but the system decided it wanted to run for 30 minutes with one push of the button ...... this is causing issues for folks who want to do a second session or further extensions note the 7:10 ending time.

How do you get this page in your FordPass app?

I don't have the "Charging" and "Cost" options, just the "Insights"

Check to see if your phone is using accessibility enhanced display, ie. larger than standard font or higher than normal zoom, it might cause the charging & cost tabs to ~disappear~

Friday morning 1/24, no spontaneous warming of the battery. Yesterday's charging session was longer and took in a lot of energy so, heat retention might be the reason, motor energy was still at 100%

I'd have to look through my logs, but I do believe they apply different heating strategies depending on whether your ignition is on or off.

To go off topic for a moment, but this is where I hope to see AI implemented. We can sit here and figure out exactly how the heater strategies of the Lightning works, and that info will be lost in 3 days as the thread ages out, or gains 5 more pages. Some AI retrieval tool within the search that could summarize all the discussions would be awesome.

Sorry, dealing with AI at work. And I would love to figure out exactly how the heater works, but I know that I'll forget and then never be able to find the three posts somewhere in some thread when I need it. How bad is it for the new guys...

Until utopia use bookmarks & tags

I feel like TaxmanHog's inputs deserve YT style clickbait titles. "90% of Forum users don't know these 3 simple tricks"

....but what happens when I have so many bookmarks that I need to complain about a way to figure out which bookmark I need?....

Back to my hole, stay frozen folks.
