Level 1/110 charging issue

[RickLightning]

Yup. Exactly your last sentence. I use level 2 FCSP at home and Level 1 at work just because it’s there. Is it even worth it? Will it at least precondition before my departure in the afternoon?

No, it will not precondition the battery on level 1.

This brings up a question I have, in cold enough weather I'm certain it won't be enough to precondition the battery. But, will it still try (and in the process waste electricity) or will it realize it's hopeless and give up to the elements?

It doesn't seem to give up. It will keep trying to use the 1kW to warm the battery. It just won't have much impact if it is soaking out the bottom of the truck as fast as it is going in. It is all relative to how cold it is. A 1kW heater running on an open porch in -20° will only slightly warm a person sitting in front of it. Everyone else still freezes. . Once it hits an equilibrium, it will hold the slight temperature increase at best.

The HV battery likely will do most of the work from what I have read, L1 just does not provide enough energy on its own. Having the L1 won't hurt in other words.

Electricity will be not 'wasted' per se - I mean some is always 'wasted' in resistance losses in the wiring and in the on-board charger, etc.

Pretty sure I have my answer but my question about waste was specifically in cold enough weather, you plug in on level 1 for a multiday charge (it is level 1 after all) and come back to a truck with less charge than when you started.
