Urgent charging question - resolved

[JohnFoxeSheets]

UPDATE: I just arrived home with 32% SoC. All’s well. (@Mach-Lee recommended that I stop the preconditioning since - paraphrasing - the priority should be getting electrons into the battery, not making the battery be in a condition to accept more.)

Thanks to all who replied!

I’m at an Airbnb with a 40A charger. Last night it should have fully charged but a bit before 1AM the circuit breaker tripped. (No idea why - the car has been charging since 9PM and the owner has used the charger many times in the past and it’s a 50A breaker.) I didn’t discover it until this morning. The car is charging again now. Checkout is at 11AM.

My question is: I have preconditioning set up for today, but I’m wondering if I should turn it off since obviously it will take away power that would otherwise go to the battery (but at the same time a warm battery chargers fast). Temps overnight we’re in the upper 30’s and I’d guess it’s in the low 40’s now.

Any thoughts?

I don't think it makes much difference. you should almost be fully charged if you've been charging for total of 8 hours. If you need additional range, just use heated seats and not the cabin heater.

If you are still plugged in to the L2 charger, and have a departure time set, it will Pre-condition without drawing from your battery. What is your state of charge right now?

SOC is now at 63%. It’s been charging this morning since about 7:10AM PST.

I think you should almost be at 100% by 11am. At 40 amps you should add 10% per hour. I would just stay on schedule.

Thanks guys. It’s at 67% and still charging; I definitely will have enough to get home. Oh, and the Airbnb host partially refunded our rental for the trouble. ?

That’s nice of Airbnb to do! Definitely not the normal there so great customer service!

The batteries like to be above 40°. And since the temps are pretty close to that already ... you can probably just skip pre-conditioning.

The refund came directly from the host - not Airbnb. But it was nice if him to do so. We didn’t ask for anything.

Even better since there are a lot of hosts that wouldn't out there. Glad to hear you found a good egg!
