Probably not in there currently, but it would be "nice" if, when plugged in, the Prime also could charge/maintain the 12V battery. Without it you aren't going anywhere.
I believe that's one of those obscure facts about the PiP. It does charge the 12V when you charge the traction battery. I'd like to think Toyota would not change that. Not sure though about the ramifications of the Solar Roof. I know it provides a charge to the 12V when under way, but not sure until we actually get one how the 12V is affected. Unsupervised!
i can't see why they would drop that feature from the pip. but keep in mind, gen 4 has a more robust battery.
You mean the 12V is more robust. Don't forget the 12V is located in the front of the car now instead of next to the traction battery like on the PiP.
