To charge or not to charge?

It depends on how often and how far you are driving. If you have enough charge to complete the second trip without charging, then I would not charge. But you know you will be needing more charge than what's left, then yes I would charge. The point is to try to use the fully charged battery as soon as possible, and maybe try to keep the charge cycle number minimum. The first part is clearly stated in the manual, but the second part is not. The charge cycle may or may not be a limiting factor in battery degradation.

The manual clearly recommends not to leave the charge cord plugged in after the completion of the charge. Doing so will drain the 12v battery quicker. And also that means you are leaving a fully charged traction battery for a prolonged time which is not good for the longevity of the traction battery. Try to use the charge schedule to minimize the time the traction battery is fully charged.

SoC= State of Charge The level of charge remaining in the traction battery usually displayed in %, but the display in PP's dash is not real SoC, but % of the EV mode usable charge. The real SoC is ~81% when the dash indicates 100% and ~14% when the dash indicates -- %(it never shows 0%).

 

There are two different functions of remote climate controls. One is the Remote A/C function using your key fob. For this to work, you have to be close enough to the fob range but the car does not need to be plugged in but requires a sufficient amount of traction battery charge is left. It does work while the car is plugged, but it does not have to be plugged in. The second is the Climate Prep function that is tied to the charge schedule. This is enabled on charge schedule with climate prep, and this will require the charge cord to be plugged in, But it only works 10min before the scheduled departure time after the charge has been completed. In both cases, the HVAC system uses exclusively pure electric heat pump (or air conditioner) to heat or cool the cabin using the traction battery. Thus in most cases, you will end up with a shorter EV range after the operation.

For PP Advanced models prior to 2019, there was a third remote phone app that controlled the Remote Climate function, but this has been discontinued in 2020 and I think it is also disabled in 2021 models.

As far as changing the calendar for the dash that is linked to scheduling, it is under setting on the MID and "Meter Customize" setting and you will see the Calendar setting. You need to get there by wheel button to the furthest right "Meter Customize" then all the way down to "Calendar".

 

AFAIK, the connecting charge cord ahead of the scheduled charge time is fine. The manual statement is about leaving the charge cord connected after completion of the charging. In theory, you might be right that there is some draining of the 12v battery by having the cord connected well in advance, but yeah, if you have to get up at 1 am to plug in the cord, then what the usefulness of the scheduling. I used to connect my charge cord every day after I came home around 4pm and had the charge schedule charge my car nightly for 6am departure. Now, I am working from home, I am not using the charge schedule. I only charge the night before if I know for sure I will be driving the next day. Otherwise, I try to keep a 30-40% charge in the traction battery most of the time. The manual suggests running the traction battery down to 0% before a long period of non-use, but for my current infrequent use about once a week, leaving a small amount of charge is more practical.

 

What Salamander_King said. I typically plug in every evening when I get hope from work and have the scheduler set to finish charging at about 5AM. What little gets drained from the 12V gets put back in while the traction battery charges because the charging system feeds 13V or so into the 12V system to maintain that battery during the charging process. The problem is when you charge it and leave it plugged in for days on end.
