crazy swiss drive going where no electric car was before....

Well, not really, but it sounds good, isn't it?
Yesterday I was invited to drive the "Alpenbrevet 2011". A night drive over around 14 alp passes and 900 Kilometer. Expected time: 20 hours.
50 cars, mainly oldtimers and one Tesla! Starting in two days at full moon!

Sounds impossible, and it is without proper preparation! It might be possible with a HPC on the right place, but like that I will do a shortened version. Between 600 and 800 Km with a charging stop of about 4 hours at 32 A ( and getting some sleep, too ).

Now I have to do the maths! I wil start hopefully fully loaded. The start is some 100 kilometers from my place and I'll have to work in the morning.

My plan is to go 200 Km, then charge with 32 for 90 minutes, gives me about 70 Km, then go 200 Km charge for 4 hours give me 150 to 200 Km Km then go for 200 Km and charge for 90 minutes with 32 A gives me about 70 Km.
That gives me: 400 + 70 + 200 +70 = 740 KM
Charging time: 7 hours
Driving time: 13 hours

And as I will drive the shortened version, this should be o.k. Well theoretically....

Thank you for your advice, but I did not understand the numbers?

So you would say to charge in performance mode, but to drive in range mode?

I f you would like to look at the map.

The plan is:
Start at 16.00 in Meiringen, fully charged. Sustenpass ( 2244m ), Andermatt, Oberalppass ( 2044m ), Disentis, Lukmanierpass ( 1914m ), Biasca, St. Bernardino Pass ( 2065m ), Splügen, Splügenpass ( 2113m ). Arriving at 22.00 in Motespluga for a dinner and may be a little recharge, if I find a socket!? So far around 260 Km.
Then Chiavena, Malojapass ( 1815 ), St. Moritz. Hope to arrive at around 0.30. Some 77 Km. Total 337. The EV friendly station St. Moritz should have installed a 32 A socket for the car and a nice room for me. Loading for about 4 hours.
Departing at around 5.00 to Julierpass ( 2284 ), Tiefencastel, Airolo, Sankt Gotthard Pass ( 2188 ), Furkapass ( 2481m ), Grimselpass ( 2165m ). Charging for 90 minutes with 32A and taking a breakfast. Meiringen, and the finish in Interlaken. Around 322 Km. Hope to arrive at around 14.00.
Then some more 80 Km to get home!

So, the run will have a total of about 657 Km. With the way to the start and from the finish, it will be around 830 Km! 10 Swiss alps crossings! The highest being Furka at 2481 m above sea.

so far so good.
330 Km - 6 Alp crossings - 5,5 hours.
Now Floating with 32A

Back at home! Car is charging and I'm recovering. I'll try to post the full story soon. But here the results of stage two:
St. Moritz - Julierpass - Tiefencastel - San Bernardino ( tunnel - the pass I did on stage one ) - Gotthardpass - Furkapass - Grimselpass - Interlaken - Bern - Murten:

Eberhard thank you I did as you told and charged in Performance mode and did drive in Range mode.
I'm preparing a small article I will post here with the details, it might get published, too.
