I'm helping doug a bit by cleaning up this forum and making this forum more "open" to new users. Some threads are very old and contain outdated information in their startposts.
How does the 45 Minute Quickcharge work?
At the October 1st 2011 event Tesla Motors revealed that the 45 minute QuickCharge of the Model S will be done with a 90kW DC charger.
The biggest battery pack will hold about 85 to 90kWh of power. Charging from a 10% SoC (State of Charge) to 80% can be done in 45 minutes. Charging to a 100% will take a longer time.
With a 30 minute charge you will get somewhere around 150 miles of range. (Only with the 300 mile pack and maybe with the 230 mile pack)
What kind of charger will they use?
Tesla claims to have developed a new in-house charger consisting of 9 10kW chargers as found in the Model S. By placing 9 of these chargers (outside the car!) in parallel they would be able to deliver 90kW of power.
What kind of connector will they be using for this?
At the same event Tesla also showed their new connector. This "Tesla-only" connector will be able to handle up to 20kW of AC power through the HPC 2.0 EVSE or 90kW of DC power with the new charger.
At the moment we are not sure which protocol Tesla will be using, but it is almost certain that without an adapter the Model S will NOT be able to charge from existing CHAdeMO chargers like used for the Nissan Leaf.
Will I be able to install this charger at home?
No, probably not. You will need a 3-phase 480V ~120A connection, not something you will find in a regular house.
Where will I find these chargers?
Tesla will be installing these DC chargers along the major interstates throughout the US (and Europe?).
A lot of discussion about this is still going on, this can be found at: Tesla DC charging network
Tesla told that the first charger will be placed at Harris Ranch, CA along the I-5.
