But those battery packs have been devoloped to be used in a driving EV. Can they also be used in a garage where the battery pack does not move at all? I mean to say that these batteries then only are used for temporary storage of electricity, so that the stored electricity can be transferred to the battery of an EV?

Benz;
You are sometimes so enthusiastically confused it's hard to grasp. A battery stores charge, whether it moves or not. Direct DC/DC battery transfer "averages" charge levels. A big battery can thus charge a small battery without losing much voltage.

"Direct DC/DC battery transfer "averages" charge levels. A big battery can thus charge a small battery without losing much voltage."

That is good.

What is the current price of such a massive battery? Does anybody have an idea?

I don´t think that todays batteries are good enough to store energy that will then charge other batteries. Batteries both "uncharge" themselves and lose capasity over time. I think a better way to store the energy would be using hydrogen. Whenever someone plugged their Tesla in, the hydrogen could be used to power a generator that would charge the car. This way you could also store more energy in less space.

So you're comfortable driving a hydrogen bomb?

Vawlkus;
No ignition A-bomb to set off the fusion reaction. Storing hydrogen is tough, though. It leaks.

If you would come up with residential, nightly park&charge garages, actually storing the energy (from a relatively small PV system) would not be beneficial or cost effective. As you would be able to sell your generated kWh at the peak (selling) price, and then charge the batteries of the cars using the off-peak (asking price). You would be able to make a pretty sustainable business out of it.

I hope they also take into account that most highways in Europe have quite high speed limits (130km/h / 80mph), which according to this blog is (in theory!) around:
- 200 miles (320km) for the 85kWh,
- 150 miles (240km) for the 60kWh.

Gentleman, driving in The Netherlands, with a 85kW Model S means that you will need definitely 4 SuperChargers.
The reason is as follows; living in the centre (say Utrecht) and driving down to the South (say Terneuzen) would mean a travel distance of 420km (2-way). Based on the fact that the speed limit on the motorway is 120 or 130km/hr it woud mean that you will need approx. 80kW as the Model S is making max. 5km at 1kW.
As the batterypack will never allow you to use 80kW you cannot even cover this distance without re-charging.
As I am driving an Ampera at this moment I KNOW that is the South West there is no possibility to charge the
batteries within less than 4-6 hours as there are no public chargers. Probably this will answer some of your queries and show that one will have to build at least four chargers in The Netherlands.

I'm assuming TM might need to put them at around 200km apart from each other. They can choose to put them in between big cities, but in the BENELUX, this becomes really odd as major cities are < 100km apart.

So here is my guestimated proposal for Belgium:
1 at the border of NL A16 (Breda)- BE E19 (A'pen)
1 at the border of FR A22 (Lille) - BE E17 (Kortrijk)
1 at the border of NL A2 (Maastricht) - BE E42(Liège)
1 at the border of LUX A3 - FR A31 (Thionville)

In NL a similar pattern around the 'Randstad' could provide the required range extension for road trips. In France and Germany the SC would more likely be positioned similar to the US pattern.

Yeah, as far apart as possible to maximize their "efficiency", but as close as necessary to make them reachable by most drivers. Of course, if the cities are really close, they're not as needed.
