Mobility facts
Facts from statistics
Cars are parked 23 hours a day
Dependent on car type 10 30 kWh are needed for 100km
Reduced fuel costs: Electrical 2-6 (20ct/kWh) vs. 7,50-12,00 (5-8l/100km, 1,50/l)
Average distance a day:

Charging scenarios
1. Plugged in at home (long charging period):
orma soc et max 3 : u y c arge a ter ~10 ours
3 phase socket max 10 kW: Fully charged after ~3 hours
2. Plugged in at service provider (parking time 1 to 6 h)
3 phase socket: 3 kW to 44 kW
3. Service at electrical gas station (recharging in < 20 min)
Exchange battery
Fast Charging up to 240 kW

Lets look at the facts:
is an electrical storage system is connected 23 hours a day to the grid with 10kW. offers in average a capacity of 30 kWh
Just imagine .1.000.000 cars are connected to the grid with 10 kW: This is a power station with max 10.000.000 kW = 10 GW.
This is comparable to 8 nuclear power stations with 1.2 GW
This would give a capacity of 30.000.000 kWh = 30 GWh:
Questions: Would the car owners allow that at all?

What could we do with a vehicle based virtual power plant which is:
completely decentralized
highly available
close to the energy consumers
We could:
Support the grid in high peak times
Avoid unnecessary energy transport through the grid
Make more efficient use of renewable energy (wind and solar power)
What would it mean to the grid:
LV and MV grid has partly to be redesigned
