From what i understand, with AC it does warm the battery up a bit as a consequence of the charging and cabin pre-heating. But it's not a feature, just a by-product, and in my experience just by a few degrees - i.e. its not going to get your HV battery from 5 to 30 degrees. Maybe 5 to 10.
Basically, no it won't and would take some time to achieve it due to the low power of the input supply.
When setting timings etc only via the HV charger, can the HV charger also stop the charging, at for example 85% SOC?
No, but you can set it up as an 85% profile in the App. It will stop charging when the battery gets to 85% (although profiles can be somewhat confusing - see elsewhere on the Forum)
Jury is still out on that one. I must have a timer to control the end of a charging session otherwise I'll end up at 100%.
You need to look at the relative costs of public charging versus home charging. Home charging will be AC based (therefore slower) and lower power (therefore slower) but for overnight charging is perfect and likely to be a cheaper regular option.
Also free charging with purchase only last normally in US for 12-24-36 mos depending on when purchased and only on Electrify America network. Great if you have one nearby and also have 350 KWT charging capes at them…then it’s 20-30 mins for full 85+% SOC. So great if and when available but can be variable depending on where you live in US and travel profile. So for me home charging even at level 2 is a no brained. Can charge overnight when electrons are cheaper. One or two charges a week at about $9-15 is good for me and waay cheaper than any gas fillips for any of my ICE vehicles So for my use installed to Wallbox 48amp chargers on separate 60amp dedicated separate circuits via each charger hardwire so charging takes me about 5hrs a night and am good to go! So that’s good for daily needs. Wireless and BT capeble to monitor charging on the Wallbox and so can monitor along with Porsche’s app as needed. Overall setup works for me so can’t say why one would NOT home charge with one of these cars.
I suspect you'll end up home charging too at some stage due to the sheer convenience of it. Why queue and charge when you can sleep and charge?
Let me be first to trailblaze this. I am betting on everyone having a home charger so I can be the only one at the dealer charging using up their $300K charger after I drop off my son to school and score a free Perrier water and kick the tires of what appears to be only sold, missing amps, or used examples in the show room.
More than likely you'll be setting up your own charger as I suspect that 1) the Porsche charger will be used on their own models and keeping cars ready to go for customers (the dealer has needs too other than charging your car daily and on the regular for free I bet). Also the dealers chargers are NOT that faster than the EV network 350kw ones. I once ran my Taycan CT4 down to less than 5% SOC and had to drop by the nearby dealership to use their sole Porsche charger to recharge my car to get my buddy back to to the airport and me home and after going to get a meal and back for oh about 1.5hrs I still only have about 30-35% SOC back in my car. To get it up above 50% would have taken much longer and I suspect Porsche would NOT have appreciated me tying up their single charger that long.
