Battery conditioning, is it worth it?

[broncoaz]

For me there is only one use-case for preconditioning, and that is when I know that I'll need all the range I can get, which is rare. Otherwise just the occasional cabin heating before leaving, here in the land of absurdly high electrical rates and relatively mild temperatures.

Due to high electricity rates I charge then unplug our EV’s when they are parked in the garage. I don’t generally need all the range I can get in the morning and don’t want to have the constant draw of the truck trying to keep its battery warm.

I've gone back and forth on this matter. I have the Chargepoint EVSE so not the best monitoring but in general by the time the dust settles it costs me an extra ~2-3kw to pre-condition. That's about $0.22-0.33 where I live so this time of year when everything is in the 20's and 30's outside I'm letting it roll. I will go back to just climate when it warms up a bit.

I did test it with the same drive over a few days and charging back to 80% put 4-5 kw back in with preconditioning and this number was like 8-9kw back in without preconditioning. Now as others have mentioned it's like 8kw to precondition but I figure I'd spend half that to just get the climate up to temp so I suppose this really comes down to how expensive one's power is. I would like to think it's talking better care of the cells but I will admit, if I was paying more for power, I'd scrutinize this process much more.
