Lightning preconditioning for departure by itself.

[potato]

There is a tech on the Mach E forum that I highly respect. He says that Ford’s strategy is that the heating will initiate at -4C and heat the battery to +5C when plugged in. So 25 to 41F. I’d guess it’s the same for the Lightning. I maintain my garage at 45F, so I’ll never find out.

It is not the same for my Lightning. Mine has certainly been colder than -4 C when I get in. If it's -10 outside, I can expect about -7 battery temp for example. As reported by CarScanner via OBD.

Unfortunately I don't have any way to monitor power usage like taxman to see if it's ever really trying.

It is actually maintaining the battery temperature above 40 degrees if plugged in. I thought the same thing. So if cold (I park mine in a carport and today it was -4 degrees) the truck will attempt to maintain at least 40 degrees regularly. It will cost you about 30-40 minutes of house supplied power to the battery heaters a cold day.

uhm, I'm pretty confident that this is incorrect, unless you by "regularly" mean hours apart where it drops way below 41 inbetween.

It was covered in another forum.

There was a factory documentation stated in other forums which address this. Everyone experiences this and many have reported it. Perhaps someone can find that factory document to show us again.

Ford needs to add the "warm my truck up now" button. I'd be willing to sing it If it makes it easier to implement ...

To be fair, the other button would be "cool my truck down now"

I agree

Closest option would be hitting Start to initiate a charge above your target % (assuming you're below 100%). Would be interesting to see battery temp after 15 or 30 minutes of charging at different rates v using departure time.

The system warms (or cools) the battery to optimize charging. Presumably, it immediately starts to warm the battery. I'm guessing the rate of warming is the same on any level 2 charger.

In other words, it's not only charging current that warms the battery, it's also the heat management system.

This is my understanding of how it works based on my observations and those of other forum members. It may be inaccurate.

Possibly. My thinking was that more of that power would go to the heater to get the battery up to temp in the beginning but who knows what arbitrary temp that is without sitting and monitoring it.

I've noticed multiple times this week that it likes to maintain about 40F while plugged in and not charging from looking at Car Scanner so not sure how much it would need to warm the battery to get optimal charge. Couldn't find the exact temp that it started spontaneously warming the battery but it's ran about 2-3x/day for an hour each this week with overnight temps between 15 and 25F. And that's even while using the 120v mobile cord.

The name of the circuit for his EVSE.

I'm using the monitor & mains sensor only for $99, but you can get packages with 8 & 16 circuit Sensors.

Thanks for the info.

I don't know what that temperature is either. I suspect it's a range. It's certainly not arbitrary.
