Indeed. It would be great if this were a new feature. The 12.5C/55F temperature of my garage was not lower than usual and I have not noticed this battery-heating phenomenon before.I think I saw another poster who posted some really detailed data from charging (really sorry to whomever that was for forgetting your name - with every day being exactly the same, my memory is shot). It seemed that the battery does pull power from the mains to heat up the battery if it is very cold, up to a threshold, and then starts to use mains power to charge the battery (at which point any increase in temperature is just from the heat dissipation). So, that would explain the quick increase to 60F - would be interested to see whether that temp increase now slows down? Kingske's data was the really surprising one though, since it kept on heating to 24C/75F even though the SoC had not gone up by much which suggests continued pre-heating of the battery - I've just not been able to get my car to do that without a timer so far (or even with a timer, since I do not use them). I'm seriously hoping this is a new thing, as it would be a game changer for Winter weather.
