Battery preconditioning

[Marcjacal]

I live in Arizona with many 100+ days. I leave the car plugged in, but have my charging time set to a narrow band at night when the garage is at its coolest. After a drive on a very hot day, I’ll sometimes get a message, it’s hot, plug car in when not in use, which I do. Any other time, I’ve seen it run the fan when I’m charging and it’s very hot, but never any indication of something happening any other time. Even after a drive on a 110+ day, I’ll plug it in, but don’t charge it. Nothing, no indication the car is doing anything. Am I supposed to hear the car doing any conditioning?

The charging times are set on the car rather than the EVSE right? For cooling to work the EVSE has to allow charging when you get home.

Yeah, I’m a bit confused. I program charging with FordPass. My charger has no brain of its own so charging cant be set with that. Are you saying the car won’t condition the battery unless my charger is setting the charge times? Or am I reading you wrong?

Okay, it's a dumb EVSE so never mind.

If it doesn't do anything when you plug in, then the battery wasn't actually hot enough to trigger cooling. It shows the message based on air temperature. If the car was parked long enough in that air temp, the battery would need cooling eventually.

I’m not an expert, but this is my interpretation. If you are driving your car, then the car is cooling the battery. When you arrive and park at home, your battery is not overheated, because it’s been cooling all along.

I am also in AZ and I have also never heard it cooling the battery randomly (while plugged in), and I also haven’t seen my charger log random charges.

So I am quite convinced that the car doesn’t randomly cool the vehicle while parked in a hot garage (110+). My guess is that if it was parked outside in the direct sun in AZ, while plugged in, perhaps it would cool the battery. I would test that theory, but it’s just too hot to go outside right now. ?
