Okay, lets make this the e-car thread.
Quote:
Automotive expert Professor Michael Bargende, former holder of the Chair of Vehicle Drives at the Institute of Automotive Engineering in Stuttgart, believes that the effort required for the charging infrastructure is completely underestimated. This is especially true when it comes not to slow AC charging in one's own garage, but to fast DC charging on highways. There, modern electric vehicles draw electricity at 100, 150, 250 or more kilowatts. Because of the special nature of the charging process, the batteries can usually only be filled to 80 percent, as the last 20 percent takes an extremely long time. Also, the charging power does not necessarily remain constant, so that the real charging time is often longer than promised by the manufacturer.
In a calculation, Bargende compared the performance of a gasoline pump with that of a charging station and came to the conclusion that, at least at peak times, such as at a busy gas station during the vacation season, the performance of a gasoline or diesel pump could only be replaced if 50 electric charging stations were available for this purpose . The calculation, Bargende said, is based on the following assumptions:
The pumping capacity of a gasoline pump is 35 liters per minute, which corresponds to 18 megawatts of energy.
Since the efficiency of the electric car is higher than that of the combustion engine by a factor of three, six megawatts of charging power are needed to achieve the same effect.
With an average charging capacity of 120 kW, this would still mean that 50 charging stations would be needed to replace one gas pump. For a typical highway service station with twelve pumps, this would theoretically require the use of 600 charging pumps.

Good luck with charging on the Autobahn once e-cras are not just the official 2% of all traffic anymore.
Goooood luuuuck... Lots and lots of it.
Maybe taking away from people the freedom of miblity is the real urpose behind all this? Lock them not down, but lock them to their place? Like in the Middle Ages the peasants were bound to the soil of their master's farmland, were not allowed to travel or move away?
