It clearly means that bacon is ready, there is a compartment inside the glovebox were you can retrieve it from.
Jk aside, that icon pops up when the car is warming up the battery to ideal temperatures, it can appear if you have schedule departure turned on, or if you turn on climate, and other, Are you charging outdoors?
Once the car gets to 99% or even 100% you will notice that the charge rate goes down significantly, and I can sit there for more than 30 minutes while is the car is calculating what “full” actually is for that particular battery pack. Since it is all chemistry based. Once the car says “Ah okay I can’t add any more energy to this pack” charging will be completed. Most people just unplug the car once it gets to 99% or hits 100% since it is not worth to wait 30+ minutes for a couple of extra miles.
