Bit late now, didn't see your original ...
I've driven to Alps a few times.
Chains are a legal requirement of course
Gendarmes have been happy with my Winter Tyres in the past (when the road was snow packed all the way up the mountain from Moutier). I made a lot better progress than the people with chains
We are rather concerned it is going to take a very very long time
With ICE we used to just change drivers, every couple of hours, except for e.g. lunch. Arrived knackered! Now, stopping every 2 hours-ish for 20 minute leg stretch we arrive in far better shape.
I just use
ABetterRoutePlanner (set temperature for e.g. 5C and RAIN if that is likely, and maybe wind=5MPH). On the way out we overnight (because of loss of an hour clock change), and we aim to stop by 7PM to get a decent meal. Choosing a location with a destination charger gets me from, say, 10% to 100% overnight - in practice probably equivalent to two normal stops. That said, for the single-day return journey we stop for lunch for an hour, and that's a 10% to 95+% charge too. Need to be organised enough to arrive at 10% to take advantage of that; at other Supercharger stops I charge to 80% regardless of how little I need to get to the next stop "just in case"
Travelling Flexi on the Chunnel there are a pair of Superchargers at the Calais Flexi Lounge - that is post-customs, so can linger there until shortly before departure (in fact I would skip a train to get a decent charge as the first UK charger, at Maidstone, is likely to be busy with other people coming off the crossing). Pre-customs Superchargers also available, both sides.
This is the return journey. Stop for an hour at 12 noon for lunch, and then at 17:00-ish at the Tunnel (waiting for our train anyway). That leaves the other 3 stops which were about 20 minutes each and 1h30m apart. The car would do 2h30m between stops (i.e. motorway range from, say, 80% to 10% at 130 KPH) but the Superchargers are not conveniently placed to allow that in practice.
Slope of the final leg shows that progress in UK traffic (and 70MPH) considerable slower / less "fuel" than France.
Does anybody have any tips on where to stop and any problems along the way
I've stopped at Macon charger
It is just off autobahn, 20 stalls but absolutely no services there. But there is quite a nice restaurant.
The restaurant at Châteauvillain-Orges (North ... maybe shared with South, not sure) services was fine.
I've overnighted at Chateau de Courban (between Troyes and Dijon, bit off the route); Michelin star restaurant.. They let me reserve a destination charger (3x Tesla chargers and 3-phase from memory)
I have plugged into domestic socket (I got a Tesla Schuko adaptor)
Garage was a bit tight!
I also charged in an underground carpark (Courcheval). Two green parking bays right by the entrance. Asked the Car park attendant about getting the appropriate card ... "You can get one at Carrefour, or I have one", can't remember the price he charged - EUR 10 perhaps. He got his card, walked to the car, started the charge, and then walked off with his card again
Mind you I was happy ...
Even with car in (unheated) garage, charging (240V) overnight, the battery was not warmed enough that regen was limited coming down the hill. So some friction brakes used - gained perhaps 2% charge, but if battery had been warm probably would have been more than that.
My trip-report from Feb 2020 if of interest
There were a number of public charge points in Morzine and Les Gets that you could get an overnight charge at but we were lucky enough to have a driveway/parking spot beside the chalet to run a cable out of the bathroom window to top up to 100%. The worst bit of the journey for us was making...
