What happens after the “departure time” is reached, but you haven’t yet departed? Does it cease battery preconditioning and cabin comforting? Or does it continue, even after the set departure time, until you unplug? (seems like this should be a toggle option, to continue preconditioning after scheduled departure time, if truck is still plugged in).
I believe everything stays active for 15 minutes and then shuts off. But the key to this theory is that the battery at some point in the morning does get to optimal which is 60°F and since it’s such a large mass, it takes quite a while for it to drop Temperature, especially if kept in a garage or better yet an insulated garage.
i’m a big fan of just let your charging be your preconditioning, so just do your charging window late in the morning before the earliest you would ever depart and if your normal target is 80% lower it to 70% and then once you know, you need to leave for somewhere quickly add the 10% as fast as you can manually. This works exceptionally good if you can charge at a higher rate than 48amps.
I would like to see an image of your wrapping work. Any chance of too much heat build-up at a DCFC with a wrapping, if the plastic is touching the plug?
When does the pre-conditioning start? 20 minutes if already on the road? I think I have seen preconditioning start about 45 minutes ahead of departure on the home L2, in 50F temperatures, only staying on about 15 minutes. Is that typical?
Your home experience is accurate, and dynamic to the pack temp's, the colder it is the further back from programmed departure time.
