The migration of nations
Each summer the same spectacle: Endless convoys of cara on the Tauern highway towards the southern beaches of Europe. Would this bee possible with exchanging batteries?
In the most extrem, it's necessary to exchange the battery 10 times from Hamburg to Sicily. But even from Munich to Istria are 2 battery exchanges necessary. The empty batteries are charged at the refill station. The stock has to be big enough to span the charging time.
When every 40 km is a big refill station and an exchange battery is for little bit more than 200 km, one from 5 cars will have to stop at the refill station. This is a complete different situation than we have now. Becaue highway gasoline stations are expensive, they are avoided as good as possible. In the dense holiday traffic, nobody can go with high speed. So they can only drive economic. Many current cars have in this driving style a range from more than 1000km. Refueled is at a cheap gasoline station at home and at a cheap gasoline station at the holiday destination.
But the exchange battery has only 20% of the range of current usual Diesel cars. With charge time, range per charge, density of the refill stations along the holiday routes and maximal traffic, it's possible to caluclate the necessary stock for exchange batteries.
The maximal stock of exchange batteries is along the holiday routes like Brenner highway or A10 Tauern highway not all the year necessary. One exchange battery could be an investment in the range of 10.000,-EUR. So the stock will be redueced during the holiday season at some locations and brought to the typicall holiday routes. A truck can only transport about 120 pieces of 200 kg heavy exchange batteries.
