I was actually surprised to see that 1 hour number, too. But that is not Rocket Science there either. It is just a parallel that double feeds the battery pack. Hardly even anything innovative. Just popped that in because you kept coming up with totally wack stupid routine -- it takes ten weeks to charge it for a one hour run type -- crap.
American homes typically get power at up to 240 volts and 200 amps and the normal three-prong outlets in the house supply it at 120 volts and 15 amps per circuit. Those standard outlets are what is known as a level 1 supply. The so-called level 2 charging stations can provide 240 volts and up to 60 amps but most homes are only wired for 30 amp, 240 volt circuits for devices like dryers and ovens. Most home level 2 stations are likely to be sitting on these 30 amp circuits. A 60 A circuit can push 14.4 kilowatts of power while a 30 A circuit does about 6.5 kW after accounting for losses in transformers. That reduced output means more than double the charging time.
However, the real bottleneck in these first EVs will be the on-board chargers that convert the AC to DC for the battery. The Nissan Leaf and Chevrolet Volt are equipped with 3.3 kW chargers which will double the charge time again. In the case of the Volt, with its smaller 16 kilowatt-hour battery (of which only 8 kWh is used), it should be able to charge in 3-4 hours on a 30 A level 2 station. The Leaf, on the other hand, uses about 90 percent of it 24 kWh capacity and will need 10-12 hours to fully charge.
In the case of the Volt, General Motors likely opted for the lower-power, lower-cost charger because the smaller battery could get by with it and slower charging will help avoid overcharging that can slash battery life. Nissan hand probably chose the 3.3 kW charger because it's a closer match for the 200 V/15 A circuits used in Japan.
Finally, because of its range extender and smaller battery, the Volt doesn't have support for DC fast charging (sometimes called, somewhat erroneously, level 3 charging). The Leaf will have optional support for 400 V DC charging, but since no AC-DC conversion is needed, this big-pipe technique simply bypasses the on-board charger and the energy goes straight to the battery.
Even at 240V the charge time for the Model S is 12 hours.
Your posts become increasingly incomprehensible. Try consolidating your thoughts into paragraphs and maybe I'll read them in more detail.
Backup FACTS for Drover:

EPA-rated power consumption for the 85 kWh model (with a starting price of $69,900 after the $7,500 federal tax credit) is 38 kWh/100 miles combined (38 kWh city, 37 kWh highway).
The battery is warrantied for 8 years, unlimited miles. Charge time at 240V according to the EPA is 12 hours. The Model S is equipped with a 10 kW capable on-board charger with the following input compatibility: 85-265 V, 45-65 Hz, 1-40 A. With a High Power Wall Connector and Twin Chargers (i.e., 20 kW capable), Model S can be recharged at the rate of 62 miles of range per hour. The 85 kWh version of the Model S is “Supercharger” equipped, allowing fast charging that will replenish 160 miles of travel in about 30 minutes when applied to the 85 kWh vehicle.
About 5 hours (hmm, not 12. Are you starting to see why I think you sound like a total bs-er?)
---------------------
But let's say I am in a hurry. Not going to sleep 5 hours tonight, only 2 or 3. So I get the High Power Wall Connector -- 240 V, 80 Amps, Twin Charger. Miles still set at 150 . . . and we get . . .

As the technology, both charging and batteries gets refined the charging times will somewhat decrease but of course that means the vehicle charging cost will come up....
And we still have that nasty problem of where these EV charging stations will be located, who will build them, who will fund them and who will repair/clean these stations once the tag artists get creative on them.
Yeah . . . and in all those (granted Texas) cities, generally poorer folks live in apartments. We used to. No shame in that, just the way things are. Next tier up tends to be rental houses -- that would be us, now. Next up is Home Owners. Those folks usually represent folks capable of actually buying bigger ticket items. Like a new EV. Do not follow your problem in this. Maybe you should check some of the wider-world?

Nope. That is why I asked you the straight simple question.

I guess you are not capable of a straight simple answer?

I can draw cartoons if that makes it simple enough for you to understand?

One can use the FUD factor and find something wrong/bad/dangerous/polluting in everything that touches our lives, seems you just have blinders on and concentrate on gasoline.....
Gasoline (and Diesel) is a/the major source of air pollution in most cities.
And generates Massive amounts of CO2 all along the production, distribution and use path.
Do you really not understand that?
Not too hard to be "Greener" than Gasoline.

So in a city you propose to place the EV charging stations where exactly? Remember, the city owns the right-of-way on the sidewalks (and Unions do the actual work)..
Yunno you would not look so dumb if you would research the topics . . . even just a little bit.

Yes, we can see from the sales figures of EV's the huge public clamor for them. After they rent these EV vehicles just where do they go to get them recharged? Do they now have to take into consideration if the hotel has 20 EV charging stations and what type they are???
A businessman flies into San Antonio International and rents an EV car to take him to Ft. Stockton. 311 miles each way and FT Stockton has no EV charging stations.... oh yeah...
You should appear on Comedy Central, your act is hilarious...
Who is renting EVs? Are you on the wrong medication or something?
The Charging Stations at the Airports are in the Parking Garages.
Folks park their car there, take a day business flight and come back and the car is charged.
The 85 kWh version of the Model S is “Supercharger” equipped, allowing fast charging that will replenish 160 miles of travel in about 30 minutes when applied to the 85 kWh vehicle.
30 Minutes. Time is shrinking faster by the post.
Holy crapola! I am barely going to have time for a Lap Dance at the Breast Tavern before the car is charged and I have to head back down the road.
You know what is comical to me on this? You have spent more time saying how long it will take to charge the car than . . . it takes to charge the car!
You gotta be retired or something, huh?
Mind if I just skip down the rest of your nonsense?

This is something.
You mean better electronic technology and equipment makes costs go up?
Glad I stuck with that $2000 Apple II PC.

And whether there will be Starbucks served at the charging station.
If so, I am betting they will be chock full of Elite Arrogant Snobs or some such cutting bidness deals.
Nasty problems abound.
